Abstract
Description
Technical Field
[0001] This invention relates to the field of tool technology, and more particularly to a decorating tool. Background Technology
[0002] Currently, a type of finishing tool is widely used for leveling, scraping, or temporarily covering building walls, gardens, or courtyard floors. Existing finishing tools employ a fixed connection structure where the relative positions of the working part and the gripping part are not adjustable. This structure is not conducive to the orderly storage of finishing tools when not in use, resulting in them occupying a significant amount of storage space and limiting the maximum transport capacity of multiple sets of finishing tools in a single batch. Furthermore, this structure cannot meet the needs of adjusting the relative positions of the working part and the gripping part in certain work situations. Summary of the Invention
[0003] Therefore, it is necessary to provide an improved decorating tool.
[0004] The present invention provides a decorating tool, including a working part, a holding part, and a connecting part. The working part and the holding part are respectively connected to the two ends of the connecting part. The holding part can be rotated through the connecting part to a position relatively close to or relatively far from the working part. The holding part can be rotated to the side of the working part and does not protrude from the end of the working part.
[0005] In one embodiment, one end of the connecting portion is connected to the middle position of the side of the working portion, and the length of the grip portion is half the length of the side of the working portion.
[0006] This design allows users to rotate the grip to a position perpendicular to the working part, creating a T-shaped symmetrical structure for the decorating tools, making them more convenient to use. It also ensures that the decorating tools have a more compact and regular shape when not in use, making them easier to store in an orderly manner.
[0007] In one embodiment, the connecting part has a lock state and an unlock state that can be switched between each other. In the unlock state, the gripping part can rotate in a direction that is relatively closer to or farther away from the working part, and in the lock state, it is fixed relative to the working part.
[0008] With this configuration, the decorating tool has an adjustable shape when the connection is unlocked and a fixed shape when the connection is locked. When the user adjusts the relative position and angle between the working part and the gripping part to the desired state and locks them together, the decorating tool can be put into use immediately.
[0009] In one embodiment, the connecting part includes a first anti-rotation part, a second anti-rotation part, and a first adjustment unit. The first anti-rotation part and the second anti-rotation part are respectively connected to the working part and the gripping part. The first adjustment unit is movably connected to the first anti-rotation part and the second anti-rotation part. The first adjustment unit has at least a first adjustment position and a second adjustment position. When the first adjustment unit moves to the first adjustment position, the first anti-rotation part and the second anti-rotation part engage to form a locked state. When the first adjustment unit moves to the second adjustment position, the first anti-rotation part and the second anti-rotation part disengage to form an unlocked state.
[0010] With this configuration, when the user needs to adjust the relative position of the working part and the gripping part, simply switch the connecting part to the unlocked state and engage the first anti-rotation part with the second anti-rotation part. After the relative position of the working part and the gripping part is adjusted, switch the connecting part back to the locked state to engage the first anti-rotation part with the second anti-rotation part. The engagement and fixation between the first and second anti-rotation parts helps to ensure that the connecting part is more secure after locking, and will not fail or be damaged during long-term use, thus improving the durability of the decorating tool.
[0011] In one embodiment, a first anti-rotation part and a second anti-rotation part are disposed opposite to each other. The first anti-rotation part is provided with a first tooth set on the side of the first anti-rotation part that is closer to the second anti-rotation part, and the second anti-rotation part is provided with a second tooth set that is adapted to the first tooth set on the side of the second anti-rotation part that is closer to the first anti-rotation part. The first adjustment unit includes a first connecting shaft and a first adjusting member. The first connecting shaft passes through the first anti-rotation part and the second anti-rotation part. The first adjusting member is movably connected to the first connecting shaft and can move relative to the first connecting shaft, so that the first anti-rotation part and the second anti-rotation part are pressed together and locked through engagement, or the first anti-rotation part and the second anti-rotation part are separated from each other and disengaged to form an unlocked state.
[0012] With this configuration, the user can switch the first adjustment unit between the first adjustment position and the second adjustment position by changing the relative position of the first adjustment member and the first connecting shaft. When the first adjustment unit is in the first adjustment position, the first anti-rotation part and the second anti-rotation part approach each other along the axial direction of the first connecting shaft and are fixed by engagement. When the first adjustment unit is in the second adjustment position, the first anti-rotation part and the second anti-rotation part move away from each other along the axial direction of the first connecting shaft and the anti-rotation fixation is released.
[0013] In one embodiment, the first adjusting member is sleeved on the first connecting shaft and threadedly connected to the first connecting shaft. The first adjusting member can move along the axial direction of the first connecting shaft to press or separate the first anti-rotation part and the second anti-rotation part.
[0014] With this configuration, the structure and connection of the first adjustment unit are simple, allowing users to easily switch between the first adjustment position and the second adjustment position by tightening or loosening the first adjustment component.
[0015] In one embodiment, the first adjusting member is hinged to the first connecting shaft. The first adjusting member includes a first protrusion. The first adjusting member is rotatable relative to the first connecting shaft and drives the first protrusion to push against the first anti-rotation part or the second anti-rotation part so that the first anti-rotation part and the second anti-rotation part are pressed together; or drives the first protrusion away from the first anti-rotation part or the second anti-rotation part so that the first anti-rotation part and the second anti-rotation part are separated.
[0016] With this configuration, the adjustment process of the first adjustment unit is simpler. The user can move the first adjustment component to drive the first protrusion to apply or unload the clamping force on the first anti-rotation part and the second anti-rotation part, making the switching process of the first adjustment unit between the first adjustment position and the second adjustment position faster and more time-saving.
[0017] In one embodiment, the first adjusting unit further includes a first elastic member, and the first connecting shaft includes a plug portion and a first stop portion connected to one end of the plug portion. The outer diameter of the first stop portion is larger than the outer diameter of the plug portion. One end of the first elastic member abuts against the first stop portion, and the other end abuts against the first anti-rotation portion or the second anti-rotation portion.
[0018] With this configuration, the first elastic element and the first stop cooperate to increase the clamping force between the first anti-rotation part and the second anti-rotation part when the first adjustment unit is in the first adjustment position, thereby further improving the reliability of the engagement between the first anti-rotation part and the second anti-rotation part.
[0019] In one embodiment, the first adjusting unit further includes a shim and a second elastic element. The second elastic element has a different elastic coefficient than the first elastic element. The first elastic element, the shim, and the second elastic element are sequentially sleeved on the first connecting shaft. The end of the first elastic element that is relatively away from the second elastic element abuts against the first anti-rotation part or the second anti-rotation part, and the end of the second elastic element that is relatively away from the first elastic element abuts against the first stop part.
[0020] With this configuration, the first elastic element and the second elastic element work together to further increase the clamping force of the first anti-rotation part and the second anti-rotation part in the meshing state. The user needs to overcome a greater elastic force than the clamping force of the first anti-rotation part and the second anti-rotation part in the meshing state to move the first adjustment element to switch the first adjustment unit from the first adjustment position to the second adjustment position. This can prevent the first adjustment unit from moving due to accidental disturbance and unlocking the first anti-rotation part and the second anti-rotation part.
[0021] In one embodiment, the first anti-rotation part or the second anti-rotation part is provided with a receiving groove, and the first elastic member, the gasket, the second elastic member and the first stop part are all received in the receiving groove.
[0022] With this design, the structure of the connection part is more compact, and the first elastic element, the gasket, and the second elastic element can be better protected by the sink.
[0023] In one embodiment, the first adjusting member further includes a second protrusion located on the same side as the first protrusion. The second protrusion is used to restrict the rotation of the first adjusting member relative to the first or second anti-rotation part when the first anti-rotation part and the second anti-rotation part are pressed together.
[0024] With this configuration, both the second protrusion and the first protrusion can apply a clamping force to the first anti-rotation part or the second anti-rotation part, and improve the stability when the first adjusting member abuts against the first anti-rotation part or the second anti-rotation part. This overcomes the problem of the first protrusion sliding relative to the first anti-rotation part or the second anti-rotation part when only the first protrusion abuts against the first anti-rotation part or the second anti-rotation part, ensuring that the first anti-rotation part and the second anti-rotation part can be stably and continuously clamped and fixed to prevent rotation.
[0025] In one embodiment, the first adjusting member further includes a bend, which is located at the end of the first adjusting member that is relatively far from the first protrusion, and the bend is bent toward the side that is relatively opposite to the first protrusion.
[0026] This design allows the user to quickly grasp the first adjustment component, making it easier for the user's hand to operate the first adjustment component with less effort and convenience.
[0027] In one embodiment, the first anti-rotation part has a first through hole, and a third tooth set is provided on the inner wall of the first through hole; the second anti-rotation part has a second through hole, and a fourth tooth set is provided on the inner wall of the second through hole; the first adjustment unit includes a locking fastener passing through the first through hole and the second through hole, and a fifth tooth set is provided on the outer peripheral wall of the locking fastener. The locking fastener can move axially within the first through hole and the second through hole, so that the fifth tooth set simultaneously engages with the third tooth set and the fourth tooth set to form a locked state; or the fifth tooth set disengages from the third tooth set and / or the fourth tooth set to form an unlocked state.
[0028] With this configuration, the user can apply force to the locking fastener, causing it to move within the first and second through holes, thereby enabling the first adjustment unit to switch between the first and second adjustment positions; and by changing the position of the locking fastener relative to the first and second anti-rotation parts, the meshing between the fifth tooth group and the third and fourth tooth groups can be changed.
[0029] In one embodiment, the locking device includes an anti-rotation fitting section and an optical shaft section connected to each other. The fifth tooth group is located on the outer peripheral wall of the anti-rotation fitting section. The locking device passes through the anti-rotation fitting section and simultaneously through the first through hole and the second through hole to form a locked state; or passes through the optical shaft section and / or the first through hole and / or the second through hole to form an unlocked state.
[0030] With this configuration, when the user unlocks the connection, it is necessary to manipulate the anti-rotation engagement section of the locking fastener to completely disengage from either the first or second through hole, or to manipulate the optical shaft section to be completely fitted by at least the first or second anti-rotation part; when the user locks the connection, it is only necessary to manipulate the fifth tooth group of the anti-rotation engagement section to fully or partially mesh with the third and fourth tooth groups simultaneously.
[0031] In one embodiment, the first adjustment unit further includes a pressing member and a third elastic member. The pressing member is fixed at the end of the optical axis section that is relatively far from the anti-rotation mating section. One end of the third elastic member is connected to the first anti-rotation part or the second anti-rotation part, and the other end can act on the pressing member, so that the fifth tooth group can simultaneously mesh with the third tooth group and the fourth tooth group through elastic thrust.
[0032] With this configuration, under normal conditions where the user does not apply force to the first adjustment unit, the third elastic element and the pressing element work together to keep the first and second anti-rotation parts in a fixed anti-rotation state, ensuring that the gripping part is fixed relative to the working part during the use of the decorating tool; when it is necessary to adjust the relative position and angle between the gripping part and the working part, the user only needs to apply force to the pressing element and overcome the elastic thrust of the third elastic element to unlock the first and second anti-rotation parts.
[0033] In one embodiment, the connecting part includes a second adjustment unit, which is connected to the working part. The second adjustment unit is used to adjust the working angle of the decorating tool.
[0034] This design helps to further improve the applicability of decorating tools, allowing users to adjust the working angle of the tools to meet shape requirements in certain situations.
[0035] In one embodiment, the second adjustment unit includes a clamp, a second connecting shaft, and a second adjusting member, and the working part also includes a support part; the clamp is sleeved on the outer peripheral wall of the support part and can rotate around the support part; one of the clamp and the support part has a third through hole, and the other has an oblong hole extending circumferentially along the support part, and the second connecting shaft passes through the third through hole and the oblong hole; the second adjusting member is movably connected to the second connecting shaft and can move relative to the second connecting shaft, so that the second connecting shaft can move within the oblong hole and be fixed at different positions within the oblong hole.
[0036] With this configuration, the second adjustment unit has a locked state where the clamp is pressed and fixed to the support part, and an unlocked state where the clamp is released from pressing and fixing the support part. By switching between the locked and unlocked states between the second adjustment unit and the working part, the working angle of the decorating tool can be changed more conveniently and quickly.
[0037] In one embodiment, the support portion has a plurality of third through holes arranged along the axial direction of the support portion; or, the support portion has a plurality of oblong holes arranged along the axial direction of the support portion.
[0038] With this configuration, users can adjust the mounting position of the clamp on the axis of the support, and thus adjust the mounting position of the grip on the side of the working part to meet the needs of users in different situations.
[0039] The decorating tool provided by this invention features a connecting part, creating a structure where the relative position between the working part and the holding part is adjustable. Users can rotate the holding part to a position relatively close to the working part, allowing the decorating tool to be stored in a stowed state. This enables the decorating tool to be stored systematically when not in use and reduces its storage space occupation. This is beneficial for increasing the maximum transport capacity of multiple sets of decorating tools in a single centralized transport and can also meet the need for adjusting the relative position between the holding part and the working part in certain work situations, thus expanding the applicability of the decorating tool. The decorating tool achieves its stowed state by rotating the holding part to the side of the working part. In this stowed state, the decorating tool has a flat and compact shape, facilitating orderly storage when not in use. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0055] Please see Figures 1 to 4 . Figure 1 This is a schematic diagram showing the state changes of the decorating tool 100 according to Embodiment 1 of the present invention; Figure 2 for Figure 1 A structural schematic diagram of the decorating tool 100 shown; Figure 3 for Figure 2 An exploded diagram of the decorative tool 100 shown; Figure 4 for Figure 2 A partial exploded diagram of the decorative tool 100 shown.
[0056] This invention provides a decorating tool 100, including a working part 10 and a holding part 20. The working part 10 is used to smooth and scrape the surfaces of objects or environments such as building walls, garden or courtyard floors, for example, removing paint layers from wall surfaces or clearing weeds and fallen leaves from floors. In other applications, the working part 10 can also be used as a paint shield. For example, when spraying paint on some objects or environmental surfaces, the working part 10 can shield certain objects or surfaces to prevent paint droplets from splashing onto the shielded surface.
[0057] Existing decorating tools use a fixed connection structure where the relative positions of the working part and the holding part cannot be adjusted. This structure is not conducive to the orderly storage of decorating tools when they are not in use, resulting in them occupying a lot of storage space and limiting the maximum transport capacity of multiple sets of decorating tools in a single centralized transport. In addition, this structure cannot meet the needs of adjusting the relative positions of the working part and the holding part in some work situations.
[0058] In view of this, the decoration tool 100 provided by the present invention further includes a connecting part 30, the working part 10 and the holding part 20 are respectively connected to the two ends of the connecting part 30, and the holding part 20 can be rotated through the connecting part 30 to a position relatively close to or relatively far away from the working part 10.
[0059] The decorating tool 100 provided by this invention, by providing a connecting part 30, forms a structure in which the relative position between the working part 10 and the holding part 20 is adjustable. The user can rotate the holding part 20 to a position relatively close to the working part 10 to transform the decorating tool 100 into a storage form, making the overall shape of the decorating tool 100 more compact and regular. In its storage form, the decorating tool 100 can be stored orderly, occupying less storage space; it also avoids mutual interference between the holding parts 20 of multiple sets of decorating tools 100, which is beneficial to increasing the maximum carrying capacity of multiple sets of decorating tools 100 in a single centralized transport; it can also meet the needs of adjusting the relative position and angle between the holding part 20 and the working part 10 in certain work situations, expanding the scope of application of the decorating tool 100.
[0060] The following provides a detailed description of the decorating tool 100 according to Embodiment 1 of the present invention. Please refer again. Figures 1 to 4 .
[0061] In Embodiment 1, the working part 10 includes a support part 11 for connecting the gripping part 20 and an execution part 12 mounted on the support part 11. The execution part 12 is used to directly contact the surface of the object to be processed or the environment. Preferably, the support part 11 and the execution part 12 are separately formed and fixedly connected. The support part 11 preferably adopts a tubular structure, with its outer peripheral wall protruding outward to form an outer flap extending along the generatrix of the tube. One side of the outer flap is provided with a plurality of mounting protrusions 111 evenly distributed along the axis of the tube.
[0062] The actuator 12 preferably adopts a rectangular flat plate structure, and its length dimension is adapted to the length of the support 11. The edge region of the actuator 12 along its length direction is attached to the outer flap surface of the support 11. At the position where it is attached to the outer flap, there are also a plurality of mounting grooves 121 that are adapted to the mounting protrusions 111. Through the one-to-one correspondence between the plurality of mounting protrusions 111 and the plurality of mounting grooves 121, the actuator 12 is detachably and fixedly installed on the support 11.
[0063] It is understood that the execution unit 12 can also be other shapes, such as a triangular plate or a trapezoidal plate, and is not limited to the structure of Embodiment 1.
[0064] In some other extended embodiments, the actuator 12 and the support 11 can also be connected by a series of rivets and rivet holes in a one-to-one correspondence, or by a series of fasteners; in addition, the actuator 12 and the support 11 can also be an integrally formed structure.
[0065] Furthermore, in Embodiment 1, the gripping part 20 includes a connector 21 and a gripping member 22 that are connected to each other. The gripping member 22 is preferably a hollow tubular or rod-shaped structural element. One end of the connector 21 extends into the interior of the gripping member 22 that is relatively close to the working part 10 and is fixedly connected to the gripping member 22. The end of the connector 21 that is relatively far away from the gripping member 22 forms an external threaded section for connecting the connecting part 30.
[0066] One end of the connecting portion 30 is fixedly connected to the outer peripheral wall of the support portion 11, and the other end is threadedly connected to the connector 21. The gripping portion 20 is rotatable relative to the working portion 10 in a plane parallel to the axis of the support portion 11 around the connecting portion 30. The connection between the support portion 11 and the connecting portion 30 divides the support portion 11 into two sections. The gripping portion 20 is rotatable and can be retracted to at least one side of the support portion 11, and the end of the gripping portion 20 that is relatively far from the connecting portion 30 does not protrude from the end of the working portion 10, that is, it is not higher than the end of the support portion 11.
[0067] With this configuration, the user can rotate the grip 20 to the side of the working part 10 to adjust the decorating tool 100 into a storage form. In the storage form, the decorating tool 100 has a flat and compact shape, which is conducive to orderly storage when not in use.
[0068] Preferably, the gripping part 20 can rotate within a range of 180° relative to the support part 11, such as... Figure 1 As shown, the grip 20 can rotate on one side of the connecting part 30, from parallel to the support part 11 to gradually perpendicular to the support part 11, and continue to rotate until the grip 20 rotates to the other side of the connecting part 30 and is parallel to the support part 11 again; one end of the connecting part 30 is connected to the middle position between the two ends of the support part 11, and the length of the side β of the working part 10, that is, the length dimension of the support part 11, is twice the length dimension of the grip 20, which can ensure that the grip 20 will not be higher than the two ends of the support part 11 when it is folded to the side of the support part 11.
[0069] With this configuration, the user can rotate the grip 20 to a position perpendicular to the working part 10 so that the decorating tool 100 forms a T-shaped symmetrical structure, making it more convenient to use. It also ensures that the decorating tool 100 has a more compact and regular shape when idle, which is conducive to the convenient and orderly storage of the decorating tool 100. In addition, the grip 20 can be adjusted to a position that is neither perpendicular to the support part 11 nor folded into the side of the support part 11, in order to adapt to more usage scenarios.
[0070] Furthermore, in Embodiment 1, the connecting part 30 has a lockable state and an unlocked state that can be switched between each other. When the holding part 20 is in the unlocked state, it can rotate in a direction that is relatively closer to or relatively farther away from the working part 10, so that the user can easily adjust the shape of the decorating tool 100. When the connecting part 30 is in the locked state, the holding part 20 is relatively fixed to the working part 10, so that the user can apply force to the working part 10 by gripping the holding part 20.
[0071] Specifically, the connecting part 30 includes a first connecting member 301, a second connecting member 302, and a first adjusting unit 303. The first connecting member 301 is fixedly connected to the gripping part 20 by being threaded to the connecting head 21. The second connecting member 302 is fixedly connected to the working part 10. The two ends of the connecting part 30 correspond to the end of the first connecting member 301 that is threaded to the connecting head 21, and the end of the second connecting member 302 that is fixed to the working part 10, respectively. The first connecting member 301 and the second connecting member 302 are angled through the first adjusting unit 303, thereby realizing the adjustment of the relative position and angle between the gripping part 20 and the working part 10.
[0072] The first connector 301 protrudes outward from the end furthest from the gripping part 20 to form a first anti-rotation part 31. The first anti-rotation part 31 has a first through hole 312 perpendicular to the axis of the gripping part 22, and a first tooth set 311 is formed at the opening edge on one side of the first through hole 312. The first tooth set 311 includes multiple tooth-shaped ribs, which are arranged radially around the axis of the first through hole 312.
[0073] The second connector 302 includes a second anti-rotation portion 32, which has a second through hole 322 perpendicular to the axis of the gripper 22, and a second tooth set 321 is formed at the opening edge on one side of the second through hole 322. The second tooth set 321 includes multiple tooth-shaped ribs, which are arranged radially around the axis of the second through hole 322.
[0074] The first anti-rotation part 31 and the second anti-rotation part 32 are arranged opposite to each other. When the first through hole 312 and the second through hole 322 are arranged collinearly, the first tooth group 311 and the second tooth group 321 are arranged opposite to each other. The first tooth group 311 and the second tooth group 321 are adapted to each other and can mesh with each other. When the multiple toothed ribs of the two mesh with each other, the first anti-rotation part 31 and the second anti-rotation part 32 can be locked and fixed, thereby preventing the first connector 301 and the second connector 302 from rotating and fixing them.
[0075] The first adjusting unit 303 includes a first connecting shaft 331 and a first adjusting member 332. The first connecting shaft 331 includes a first insertion portion 3312 and a first stop portion 3311 fixed to one end of the first insertion portion 3312. The first insertion portion 3312 passes through a first through hole 312 and a second through hole 322. The outer diameter of the first stop portion 3311 is larger than the outer diameter of the first insertion portion 3312 and larger than the inner diameters of the first through hole 312 and the second through hole 322. The axial length of the first insertion portion 3312 is greater than the sum of the axial lengths of the first through hole 312 and the second through hole 322.
[0076] The first anti-rotation portion 31 forms a first contact surface 313 at the opening edge of the first through hole 312 on the side relatively away from the first tooth group 311, and the second anti-rotation portion 32 forms a second contact surface 323 at the opening edge of the second through hole 322 on the side relatively away from the second tooth group 321. The first stop portion 3311 abuts against the first contact surface 313, and the end of the first insertion portion 3312 that is relatively away from the first stop portion 3311 extends out of the second anti-rotation portion 32 and is higher than the second contact surface 323.
[0077] It is understood that in other embodiments, the first stop portion 3311 may also abut against the second contact surface 323, and the first insertion portion 3312 extends out of the first anti-rotation portion 31 and is higher than the first contact surface 313 at the end that is relatively away from the first stop portion 3311.
[0078] The outer peripheral wall of the end of the first insertion portion 3312 that is relatively far from the first stop portion 3311 is also provided with external threads. The first adjusting member 332 is sleeved on the end of the first insertion portion 3312 that is relatively far from the first stop portion 3311 and is threadedly connected to the first insertion portion 3312. The first adjusting member 332 can move on the first insertion portion 3312. When the first adjusting member 332 moves close to the first stop portion 3311, the first stop portion 3311 and the first adjusting member 332 cooperate to press and engage the first anti-rotation portion 31 and the second anti-rotation portion 32 to form an anti-rotation fixation.
[0079] The first adjusting member 332 can move towards the first stop portion 3311 to the first adjusting position. When the first adjusting member 332 and the first stop portion 3311 act together on the mutually opposing first contact surface 313 and second contact surface 323, and press the first anti-rotation portion 31 and the second anti-rotation portion 32 into a tight fit, so that the first tooth set 311 and the second tooth set 321 mesh with each other, the position of the first adjusting member 332 is the first adjusting position. When the first adjusting member 332 spirals to the first adjusting position, a locked anti-rotation state is formed between the first connecting member 301 and the second connecting member 302, so the connecting portion 30 locks the gripping portion 20 and the working portion 10 to prevent rotation.
[0080] The first adjusting member 332 can also move away from the first stop 3311 to a second adjusting position. When the distance between the first adjusting member 332 and the first stop 3311 increases, forming a space allowance for the first anti-rotation part 31 and the second anti-rotation part 32 to move away from each other along the axis of the first connecting shaft 331, and at the same time the first tooth set 311 and the second tooth set 321 separate and disengage, allowing the first connecting member 301 and the second connecting member 302 to rotate relative to each other, the position of the first adjusting member 332 is the second adjusting position. When the first adjusting member 332 moves to the second adjusting position, the first anti-rotation part 31 and the second anti-rotation part 32 disengage, and the anti-rotation fixation between the first connecting member 301 and the second connecting member 302 is also released. Subsequently, the gripping part 20 and the working part 10 can rotate relative to each other, so the connecting part 30 unlocks the gripping part 20 and the working part 10.
[0081] It is understood that in some other embodiments, the first connecting shaft 331 may not have a first stop 3311. In this case, the first contact surface 313 and the second contact surface 323 extend from both ends of the first connecting shaft 331, respectively, and are threadedly connected to both ends of the first connecting shaft 331 by two first adjusting members 332. By moving the two first adjusting members 332 closer to or further away from the first connecting shaft 331, the switching between engagement and disengagement between the first anti-rotation part 31 and the second anti-rotation part 32 is adjusted.
[0082] Preferably, in Embodiment 1, the first adjusting member 332 is a wing nut. The user can directly and manually clamp the wing plate of the wing nut to drive the first adjusting member 332 to move spirally on the first connecting shaft 331 without the need for other external tools, thus making the manual adjustment operation of the first adjusting unit 303 more convenient.
[0083] It is understood that the first anti-rotation part 31 and the second anti-rotation part 32 are not limited to a meshing anti-rotation fit, but can also form an anti-rotation fit through static friction to achieve locking anti-rotation of the first connecting member 301 and the second connecting member 302. When the first adjusting member 332 moves to the first adjusting position, the first adjusting member 332 and the first stop part 3311 act together on the first contact surface 313 and the second contact surface 323, thereby increasing the pressure and static friction of the contact surfaces of the first anti-rotation part 31 and the second anti-rotation part 32, and can also achieve the effect of locking the gripping part 20 and the working part 10, and is not limited to the technical solution of forming a locking state through meshing in Embodiment 1.
[0084] Please refer to it again. Figure 7 The connecting part 30 also includes a second adjustment unit 40, which connects the connecting part 30 to the support part 11. The second adjustment unit 40 is used to adjust the working angle of the decorating tool 100.
[0085] The working angle refers to the angle between the gripping part 20 and the actuating part 12 during the rotation of the gripping part 20 in a plane perpendicular to the axis of the supporting part 11 when the gripping part 20 rotates to a position perpendicular to the supporting part 11.
[0086] Specifically, the second adjustment unit 40 includes a clamp 41, a second connecting shaft 42, and a second adjusting member 43. The clamp 41 is fixedly connected to the second connecting member 302 and is sleeved or wrapped around the outer peripheral wall of the support part 11, and can rotate in a plane perpendicular to the axis of the support part 11. The second connecting shaft 42 and the second adjusting member 43 cooperate to fix the clamp 41 to the support part 11 and prevent the clamp 41 from falling off and separating from the support part 11.
[0087] The clamp 41 is formed on the second connector 302 at one end relatively away from the second anti-rotation portion 32, and is integrally formed with the second anti-rotation portion 32. The clamp 41 includes two opposing clamping plates 401, with a clamping channel 402 formed between the two clamping plates 401 for encircling or fitting the support portion 11. The clamping channel 402 is a through hole or through groove extending perpendicular to the second through hole 322. It can be understood that in other embodiments, the clamp 41 and the second anti-rotation portion 32 can also be separately formed and fixedly connected.
[0088] Preferably, a cylindrical surface is formed between the two clamping plates 401 that is adapted to the outer peripheral wall of the support portion 11. When the clamping member 41 surrounds or sleeves the support portion 11, the second connecting member 302 can rotate around the axis of the support portion 11, and drive the gripping part 20 connected to the connecting part 30 to rotate around the axis of the support portion 11.
[0089] This design helps to further improve the applicability of the decorating tool 100. Users can adjust the working angle of the decorating tool 100 to meet the shape requirements for use in certain special occasions. For example, the decorating tool 100 can be used as a shovel.
[0090] Furthermore, the clamp 41 is provided with an oblong hole 411 extending circumferentially along the support portion 11, and the support portion 11 is provided with a third through hole 412 whose inner diameter matches the width of the oblong hole 411. The second connecting shaft 42 includes a second insertion portion 422 passing through the third through hole 412 and the oblong hole 411. During the rotation of the clamp 41 around the axis of the support portion 11, the third through hole 412 can move relative to the oblong hole 411 along the extending direction of the oblong hole 411, and drive the second connecting shaft 42 to move relative to the support portion 11 within the oblong hole 411.
[0091] Preferably, the second connecting shaft 42 further includes a second stop 421 fixed to one end of the second insertion portion 422. The outer diameter of the second stop 421 is larger than the inner diameter of the third through hole 412 and the width of the oblong hole 411, and it can abut against the outer wall of one of the clamping plates 401; the end of the second insertion portion 422 that is relatively away from the second stop 421 extends out of the outer wall of the other clamping plate 401; the end of the second insertion portion 422 that is relatively away from the second stop 421 is provided with an external thread, and the second adjusting member 43 is sleeved on the end of the second insertion portion 422 that is relatively away from the second stop 421 and is threadedly connected to the second insertion portion 422. That is, the second stop 421 and the second adjusting member 43 are respectively provided on both sides of the two opposite outer walls of the two clamping plates 401.
[0092] The second adjusting member 43 can move towards the second stop 421 and work together with the second stop 421 to press the support 11 into the locking channel 402 between the two clamping plates 401, so that the inner sidewalls of the two clamping plates 401 are pressed tightly against the outer peripheral wall of the support 11. The second adjusting member 43 can also move away from the second stop 421 to create a space allowance for the two clamping plates 401 to move away from each other in an elastic deformation manner, thereby releasing the clamping force of the clamping member 41 on the support 11. At this time, the clamping member 41 can rotate in a plane perpendicular to the axis of the support 11, so that the third through hole 412 slides along the extension direction of the oblong hole 411, thereby changing the position of the second connecting shaft 42 in the oblong hole 411, so as to adjust the angle between the gripping part 20 and the plane where the actuating part 12 is located.
[0093] When the clamping force of the clamp 41 on the support 11 is released, the user controls the relative rotation between the support 11 and the clamp 41, readjusts the movement of the second adjusting member 43 on the second connecting shaft 42 close to the second stop 421, and presses the support 11 between the two clamping plates 401 again, thus realizing a change in the fixed position of the second connecting shaft 42 in the waist-shaped hole 411.
[0094] The second adjustment unit 40 has a locked state where the clamp 41 is pressed and fixed to the support part 11, and an unlocked state where the clamp 41 is released from pressing and fixing the support part 11. The locking and unlocking switching operation between the second adjustment unit 40 and the working part 10 allows for a more convenient and faster change of the working angle of the decorating tool 100. It is understood that when the second adjustment member 43 moves away from the second stop part 421, the support part 11 can also move between the two clamping plates 401 along the extension direction of the locking channel 402. Furthermore, it is understood that the aforementioned third through hole 412 can also be formed on the two clamping plates 401 of the clamp 41, and the oblong hole 411 can be formed on the peripheral wall of the support part 11 and extend circumferentially along the support part 11. During the rotation of the clamp 41 around the axis of the support 11, the third through hole 412 can still move relative to the waist-shaped hole 411 along the extension direction of the waist-shaped hole 411. When the second connecting shaft 42 passes through the third through hole 412 and the waist-shaped hole 411, the position of the second connecting shaft 42 in the waist-shaped hole 411 can also be changed by adjusting the clamp 41 to rotate in a plane perpendicular to the axis of the support 11, and is not limited to the structure of Embodiment 1.
[0095] In some other embodiments, the second connecting shaft 42 may not have a second stop 421. Both ends of the second connecting shaft 42 extend out from the outer walls of the two clamping plates 401, and two second adjusting members 43 are provided, fitted onto the ends of the second connecting shaft 42 and threadedly engaged with it. By moving the two second adjusting members 43 closer to or further away from the second connecting shaft 42, the clamping force applied to the clamping member 41 by the first anti-rotation part 31 and the second anti-rotation part 32 is adjusted.
[0096] Preferably, the second adjusting member 43 is a wing nut that is sleeved on and threadedly engaged with the second connecting shaft 42. It is understood that the second adjusting member 43 can also be a movable snap-fit, latch, or other type of adjusting element with a locking function.
[0097] In a preferred embodiment, the support portion 11 is provided with a plurality of third through holes 412, which are arranged and distributed along the axial direction of the support portion 11; or, the support portion 11 is provided with a plurality of oblong holes, which are arranged and distributed along the axial direction of the support portion 11.
[0098] With this configuration, the second connecting shaft 42 can be inserted into different third through holes 412 or oblong holes 411, allowing the clamp 41 to be fitted or wrapped around the support 11 at different positions along its axial direction. Users can adjust the axial installation position of the clamp 41 on the support 11 and the installation position of the grip 20 on the side of the working part 10 to further improve the applicability of the decorating tool 100 and meet the user's needs in different situations.
[0099] The decorating tool 100 provided in Embodiment 1 has a simple structure and is easy to adjust. The user manually rotates the wing nut to make it spiral on the first connecting shaft 331, changing the distance between the wing nut and the first stop 3311. This allows the first adjusting unit 303 to switch between applying or unapplying clamping force to the first anti-rotation part 31 and the second anti-rotation part 32, thereby switching the connecting part 30 between a locked and unlocked state. The user can tighten the wing nut to lock the angle and relative position between the gripping part 20 and the working part 10, or loosen the wing nut to unlock the gripping part 20 and the working part 10, thus adjusting the relative position and angle between the working part 10 and the gripping part 20.
[0100] The following is a decoration tool 100 according to Embodiment 2 of the present invention. The decoration tool 100 provided in Embodiment 2 has a basically the same structure as the decoration tool 100 provided in Embodiment 1, except that the structure of the first adjusting member 332 is different in Embodiment 2. Please refer to Figures 5 to 10 . Figure 5 This is a schematic diagram of the structure of the decoration tool 100 according to Embodiment 2 of the present invention; Figure 6 for Figure 5 An exploded diagram of the decorative tool 100 shown; Figure 7 for Figure 5 A partial exploded diagram of the decorative tool 100 shown; Figure 8 for Figure 5 A cross-sectional view of the first adjustment unit 303 of the decorative tool 100 in the first adjustment position; Figure 9 for Figure 5 A cross-sectional view of the first adjustment unit 303 of the decorative tool 100 shown in the position of the elastic compression limit. Figure 10 for Figure 5 A cross-sectional view of the first adjustment unit 303 of the decorative tool 100 in the second adjustment position.
[0101] In Embodiment 2, the first adjusting member 332 is a lever handle. The first adjusting member 332 is rotatably connected to the first connecting shaft 331. The user rotates the first adjusting member 332 and changes the angle between the first adjusting member 332 and the first connecting shaft 331 to switch the locking state and switching state of the connecting part 30.
[0102] Similar to Embodiment 1, the first connecting shaft 331 includes a first insertion portion 3312 and a first stop portion 3311 fixed to one end of the first insertion portion 3312. The outer diameter of the first stop portion 3311 is larger than the inner diameter of the first through hole 312 and the second through hole 322. The axial length of the first insertion portion 3312 is greater than the sum of the axial lengths of the first through hole 312 and the second through hole 322. The first insertion portion 3312 extends into the second through hole 322 and the first through hole 312 from the side of the second through hole 322 that connects to the second contact surface 323, extends out of the first contact surface 313, and the first stop portion 3311 abuts against the second contact surface 323.
[0103] The first insertion part 3312 extends out of the first contact surface 313 and has a first pin hole 3313 that passes through it. The axis of the first pin hole 3313 is perpendicular to the axis of the first insertion part 3312. The first adjusting member 332 includes a handle part 3324 and a first protrusion 3321 fixed to the side wall of the handle part 3324. A second pin hole 3326 passes through the first protrusion 3321.
[0104] The first adjustment unit 303 also includes a handle pin 3325 passing through the first pin hole 3313 and the second pin hole 3326, and the first adjustment member 332 is hinged to the first insertion part 3312 through the handle pin 3325.
[0105] A first protrusion 3321 is formed on the side of the handle portion 3324, is cam-shaped, and protrudes toward the first contact surface 313. During the rotation of the first adjusting member 332 relative to the first connecting shaft 331, the first protrusion 3321 abuts against the first contact surface 313 and pushes the first anti-rotation portion 31 closer to the second anti-rotation portion 32. That is, the first protrusion 3321 and the first stop portion 3311 work together to apply a clamping force to the first anti-rotation portion 31 and the second anti-rotation portion 32, while causing the first tooth set 311 and the second tooth set 321 to approach each other and mesh, so as to achieve the anti-rotation fixed connection between the first anti-rotation portion 31 and the second anti-rotation portion 32.
[0106] In addition, the first protrusion 3321 can also move away from the first contact surface 313 as the first adjusting member 332 rotates relative to the first connecting shaft 331, thereby increasing the distance between the first protrusion 3321 and the first stop portion 3311. This creates a space allowance for the first anti-rotation portion 31 and the second anti-rotation portion 32 to move away from each other along the axial direction of the first connecting shaft 331, so that the first tooth set 311 and the second tooth set 321 can be separated and disengaged.
[0107] Specifically, there are two first protrusions 3321, and a gap is formed between the two first protrusions 3321 to allow the first insertion part 3312 to pass through. It can be understood that there can also be only one first protrusion 3321, as long as it can abut against and apply a pushing force to the first contact surface 313.
[0108] Furthermore, the first adjusting member 332 also includes a second protrusion 3322 and a bent portion 3323. The second protrusion 3322 and the first protrusion 3321 are both fixed on the same side of the handle portion 3324. The second protrusion 3322 and the first protrusion 3321 can both abut against and push the first contact surface 313. The bent portion 3323 is located at the end of the handle portion 3324 that is relatively far away from the first protrusion 3321, and bends in a direction away from the first protrusion 3321 and the second protrusion 3322, so that it can be easily grasped and turned by the user.
[0109] Furthermore, the first adjustment unit 303 also includes a first elastic element 333, a gasket 334, and a second elastic element 335. The first elastic element 333 and the second elastic element 335 have different elastic coefficients, and the deformation they produce when subjected to external forces of different magnitudes is different.
[0110] Preferably, the first elastic element 333 is a telescopic spring with a small elastic coefficient, and the second elastic element 335 is an elastic washer with a large elastic coefficient. The first elastic element 333, the washer 334, and the second elastic element 335 are sequentially fitted onto the first insertion portion 3312 of the first connecting shaft 331. The two sides of the washer 334 respectively abut against the first elastic element 333 and the second elastic element 335, which can prevent the first elastic element 333 and the second elastic element 335 from intruding into or nesting under pressure, thus forming a reliable series arrangement on the first connecting shaft 331.
[0111] The difference in elastic modulus between the first elastic element 333 and the second elastic element 335 means that they can be made of materials with different elastic moduli, or they can be made of the same material but with different cross-sectional dimensions, or they can have different materials and different cross-sectional dimensions.
[0112] The second anti-rotation portion 32 also has a receiving groove 34 communicating with the second through hole 322, for accommodating the first elastic member 333, the gasket 334, and the second elastic member 335. The end of the first elastic member 333 that is relatively away from the second elastic member 335 abuts against the bottom wall of the receiving groove 34, and the end of the second elastic member 335 that is relatively away from the first elastic member 333 abuts against the first stop portion 3311. It can be understood that the receiving groove 34 can also be formed in the first anti-rotation portion 31 and communicate with the first through hole 312. In this case, the first stop portion 3311 abuts against the first contact surface 313, and the first protrusion 3321 abuts against the second contact surface 323.
[0113] Under the action of the first protrusion 3321 and the first stop 3311 abutting against the first anti-rotation part 31 and the second anti-rotation part 32 and applying a pressing force, the first elastic member 333 and the second elastic member 335 are compressed in the receiving groove 34 and produce elastic contraction deformation, and apply elastic thrust to the first connecting shaft 331.
[0114] When the user rotates the first adjusting member 332 and moves the first protrusion 3321 and the second protrusion 3322 away from the first contact surface 313, the space between the first protrusion 3321 and the first stop 3311, which causes the first anti-rotation portion 31 and the second anti-rotation portion 32 to move away from each other along the axial direction of the first connecting shaft 331, can assist the first adjusting unit 303 in releasing the elastic contraction potential energy accumulated in the first elastic member 333 and the second elastic member 335. The first connecting shaft 331 is pushed by the first elastic member 333 and the second elastic member 335 in a direction away from the first adjusting member 332. That is to say, the first elastic member 333 and the second elastic member 335 have a tendency to push the first connecting shaft 331 away from the first through hole 312 and the second through hole 322 in a direction away from the first adjusting member 332.
[0115] It is understood that in other embodiments, only one of the first elastic member 333 and the second elastic member 335 may be provided. The two ends of the elastic member are respectively connected to the bottom of the receiving groove 34 and the first stop 3311. As long as an elastic thrust can be applied to the first connecting shaft 331, it can have the tendency to push the first connecting shaft 331 away from the first through hole 312 and the second through hole 322 in a direction away from the first adjusting member 332.
[0116] The first adjustment unit 303 has at least three position states: a first adjustment position, a second adjustment position, and a compression limit position of the elastic element. Please refer again. Figures 8 to 10The first adjusting member 332 can rotate relative to the first connecting shaft 331 in a plane parallel to the axis of the first connecting shaft 331 and move to the first adjusting position, so that the connecting part 30 reaches the locked state. It can also rotate to the compression limit position of the elastic member, so that the first adjusting unit 303 generates the instantaneous maximum clamping force on the first anti-rotation part 31 and the second anti-rotation part 32. It can also rotate to the second adjusting position, so that the connecting part 30 reaches the unlocked state.
[0117] The state of the first adjustment unit 303 corresponding to the first adjustment position is as follows: the first protrusion 3321 and the second protrusion 3322 simultaneously abut against the first contact surface 313, the first stop portion 3311 abuts against the second contact surface 323, the first anti-rotation portion 31 and the second anti-rotation portion 32 are pressed tightly together under the combined action of the first adjustment member 332 and the first stop portion 3311, and at the same time, the first tooth set 311 and the second tooth set 321 mesh with each other. The position of the first adjustment member 332 relative to the first connecting shaft 331. At this time, the first connecting member 301 and the second connecting member 302 are fixed in place, the first elastic member 333 is in a state of extreme compression, and the second elastic member 335 is in a free state or a state of incomplete compression. The first elastic member 333 and the second elastic member 335 jointly apply an elastic thrust to the first stop portion 3311, and have a tendency to push the first connecting shaft 331 to move away from the first adjustment member 332. Under this movement trend, both the first protrusion 3321 and the second protrusion 3322 apply a pressing force to the first contact surface 313, so that the first adjusting member 332 reaches a balanced state of stable contact with the first anti-rotation part 31. The first protrusion 3321 and the second protrusion 3322 jointly abut against the first contact surface 313, which can improve the stability of the pressing contact between the first adjusting member 332 and the first anti-rotation part 31 and the second anti-rotation part 32, and can prevent the first adjusting member 332 from rotating due to accidental disturbance, prevent the first adjusting member 332 from sliding relative to the first contact surface 313, and thus prevent the first anti-rotation part 31 and the second anti-rotation part 32 from being released from the pressing state.
[0118] The state of the first adjustment unit 303 corresponding to the compression limit position of the elastic element is as follows: the user rotates the first adjustment member 332 by a preset angle, the handle part 3324 drives the second protrusion 3322 to disengage from the first contact surface 313, and at the same time drives the first protrusion 3321 to rotate, so that the distance between the point on the first contact surface 313 that contacts the first protrusion 3321 and the first pin hole 3313 in the axial direction of the first connecting shaft 331 is slightly increased, the first protrusion 3321 still abuts against the first contact surface 313 and applies a pressing force to the first contact surface 313; at the same time, the first adjustment member 332 drives the first connecting shaft 331 to move a certain distance in the direction close to the first adjustment member 332, and the second elastic element 335 is further compressed.
[0119] In this position, the combined compressive deformation of the first elastic element 333 and the second elastic element 335 reaches its maximum value, and the compressive deformation of both reaches their respective limit values. The elastic thrust acting on the first stop part 3311 by both reaches its peak value, and the first adjustment unit 303 reaches a critical equilibrium state, applying the maximum instantaneous clamping force to the first anti-rotation part 31 and the second anti-rotation part 32. This clamping force is greater than the clamping force of the first adjustment element 332 on the first anti-rotation part 31 and the second anti-rotation part 32 in the first adjustment position.
[0120] On the one hand, when the user moves the first adjusting member 332 to the state corresponding to the compression limit position of the elastic member, the maximum instantaneous clamping force must be overcome in order for the first adjusting unit 303 to cross the compression limit position of the elastic member and drive the first protrusion 3321 and the second protrusion 3322 to leave the first contact surface 313, thereby releasing the anti-rotation fixed state of the first anti-rotation part 31 and the second anti-rotation part 32. On the other hand, the user must overcome the maximum instantaneous clamping force in order for the first adjusting unit 303 to cross the compression limit position of the elastic member and drive the first protrusion 3321 and the second protrusion 3322 to abut against the first contact surface 313, thereby working together with the first stop part 3311 to apply clamping force to the first anti-rotation part 31 and the second anti-rotation part 32, thereby achieving the anti-rotation fixed state of the first anti-rotation part 31 and the second anti-rotation part 32.
[0121] The state of the first adjustment unit 303 corresponding to the second adjustment position is as follows: After the user continues to rotate the first adjustment member 332 in the aforementioned elastic member compression limit position, both the first protrusion 3321 and the second protrusion 3322 disengage from the first contact surface 313, and a space margin is generated between the first adjustment member 332 and the first stop 3311, which allows the first anti-rotation part 31 and the second anti-rotation part 32 to move away from each other along the axial direction of the first connecting shaft 331. In the aforementioned elastic member compression limit position state, the elastic compression potential energy accumulated by the first elastic member 333 and the second elastic member 335 is quickly released and pushes the first connecting shaft 331 to move away from the first adjustment member 332. At this time, a space margin is formed between the first tooth set 311 and the second tooth set 321, which allows them to separate and disengage. The second adjustment position releases the anti-rotation fixed engagement state between the first connecting member 301 and the second connecting member 302, allowing the connecting part 30 to switch to the unlocked state. In this state, the user can rotate the grip part 20 to adjust the angle and relative position between the grip part 20 and the support part 11.
[0122] When the first adjusting unit 303 is in the first adjusting position and the elastic element compression limit position, the first stop portion 3311 is always located within the receiving groove 34 and is not higher than the opening edge of the receiving groove 34. This configuration can prevent external objects from accidentally touching the first connecting shaft 331, causing the first connecting shaft 331 to deflect or loosen within the first through hole 312 or the second through hole 322, and can better protect the first elastic element 333 and the second elastic element 335 located within the receiving groove 34.
[0123] In some other embodiments, the first elastic element 333 and the second elastic element 335 may not be provided. The first adjusting element 332 and the first stop part 3311 can jointly apply a clamping force to the first anti-rotation part 31 and the second anti-rotation part 32, which can also achieve the clamping and anti-rotation cooperation between the two.
[0124] The decorating tool 100 provided in Embodiment 2 allows for quick and easy adjustment. Users can rotate the lever handle to make it rotate in a plane parallel to the axis of the first connecting shaft 331, changing the distance between the first protrusion 3321, the second protrusion 3322, and the first stop 3311. This allows the first adjusting unit 303 to switch between applying and unapplying clamping force to the first anti-rotation part 31 and the second anti-rotation part 32. The first elastic element 333 and the second elastic element 335 have a tendency to push the first connecting shaft 331 away from the first adjusting element 332, providing assistance and ensuring that the first adjusting unit 303, in the first adjusting position, maintains a stable and reliable anti-rotation fixed fit between the first anti-rotation part 31 and the second anti-rotation part 32.
[0125] Please see Figure 11 , Figure 11 This is a partially exploded view of the decorating tool 100 according to Embodiment 3 of the present invention. The following is a description of the decorating tool 100 according to Embodiment 3 of the present invention. The difference from Embodiment 1 lies in the structure of the first adjusting unit 303 in Embodiment 3, and the different methods of fixing and unlocking the first anti-rotation part 31 and the second anti-rotation part 32.
[0126] In Embodiment 3, there are two first anti-rotation parts 31, and a rotation gap 3122 is formed between the two first anti-rotation parts 31 to accommodate the second anti-rotation part 32. Each first anti-rotation part 31 has a first through hole 312, and a third tooth group 3121 is provided on the inner wall of each first through hole 312, that is, there are two third tooth groups 3121. Each third tooth group 3121 is composed of multiple tooth-shaped ribs extending along the axial direction of the first through hole 312, and the multiple tooth-shaped ribs are arranged around the axis of the first through hole 312. The second anti-rotation part 32 has a second through hole 322, and a fourth tooth group 3221 is provided on the inner wall of the second through hole 322. The fourth tooth group 3221 is composed of multiple tooth-shaped ribs extending along the axial direction of the second through hole 322, and the multiple tooth-shaped ribs are arranged around the axis of the second through hole 322.
[0127] The third tooth group 3121 and the fourth tooth group 3221 have the same number of tooth-shaped ribs. When the second anti-rotation part 32 is placed in the rotation gap 3122 between the two first anti-rotation parts 31 and the first through hole 312 and the second through hole 322 are coaxially arranged, the fourth tooth group 3221 is located between the two third tooth groups 3121.
[0128] Furthermore, in Embodiment 3, the first adjustment unit 303 includes a locking fastener 336 passing through the first through hole 312 and the second through hole 322. The locking fastener 336 preferably has a shaft-shaped structure, including an anti-rotation fitting section 3362 and a smooth shaft section 3363 connected to each other, capable of axial movement within the first through hole 312 and the second through hole 322. The outer diameter of the anti-rotation fitting section 3362 is adapted to the inner diameter of the first through hole 312 and the second through hole 322. A fifth tooth set 3361 is provided on the outer peripheral wall of the anti-rotation fitting section 3362. The fifth tooth set 3361 consists of multiple tooth-shaped ribs arranged around the axis of the locking fastener 336 and extending along the axial direction of the locking fastener 336.
[0129] Specifically, the number of tooth-shaped ribs in the fifth tooth group 3361 is the same as the number of tooth-shaped ribs in the third tooth group 3121 and the fourth tooth group 3221. Moreover, the shape of any tooth-shaped rib in the fifth tooth group 3361 is adapted to the shape of the groove between any two tooth-shaped ribs in the third tooth group 3121 and the fourth tooth group 3221. That is, any tooth-shaped rib in the fifth tooth group 3361 can be embedded in the groove between any two tooth-shaped ribs in the third tooth group 3121, and can also be embedded in the groove between any two tooth-shaped ribs in the fourth tooth group 3221. The fifth tooth group 3361 can mesh with the third tooth group 3121 and the fourth tooth group 3221.
[0130] The fifth tooth group 3361 is not provided on the outer peripheral wall of the optical axis segment 3363. Preferably, the outer diameter of the optical axis segment 3363 is smaller than the minimum outer diameter of the anti-rotation fitting segment 3362. The fifth tooth group 3361 will not engage with the third tooth group 3121 or the fourth tooth group 3221 if and only if the optical axis segment 3363 passes through the first through hole 312 or the second through hole 322, and the anti-rotation fitting segment 3362 does not pass through the first through hole 312 or the second through hole 322. At this time, the locking fastener 336 can rotate in the first through hole 312 or the second through hole 322.
[0131] It is understood that in other embodiments, two second anti-rotation portions 32 may be provided, and one first anti-rotation portion 31 may be provided. A rotational gap 3122 is formed between the two second anti-rotation portions 32 to accommodate the first anti-rotation portion 31, and the first anti-rotation portion 31 is clamped within the rotational gap 3122 between the two second anti-rotation portions 32; or, there may be only one first anti-rotation portion 31 and one second anti-rotation portion 32, as long as the locking fastener 336 can move within the first through hole 312 and the second through hole 322, driving the fifth tooth group 3361 to switch between a state in which it is simultaneously engaged and fixed with the third tooth group 3121 and the fourth tooth group 3221, and a state in which it is completely disengaged from the third tooth group 3121 or the fourth tooth group 3221.
[0132] In Embodiment 3, the first adjustment unit 303 has a first adjustment position and a second adjustment position. The first adjustment position corresponds to the state of the first adjustment unit 303 where the anti-rotation mating section 3362 is simultaneously inserted into the first through hole 312 and the second through hole 322. At this time, the fifth tooth group 3361 forms an engagement connection with the third tooth group 3121 and the fourth tooth group 3221, and the locking fastener 336 locks the first anti-rotation part 31 and the second anti-rotation part 32 together, so that the connecting part 30 is in a locked state.
[0133] The second adjustment position corresponds to the state of the first adjustment unit 303 as follows: the anti-rotation engagement section 3362 is completely disengaged from at least one of the first through hole 312 and the second through hole 322, or the optical shaft section 3363 is completely inserted into at least one of the first through hole 312 and the second through hole 322. At this time, the fifth tooth group 3361 is completely disengaged from at least one of the third tooth group 3121 and the fourth tooth group 3221, and the first anti-rotation part 31 and the second anti-rotation part 32 are no longer simultaneously locked by the anti-rotation engagement section 3362, and the two are in an unlocked state. When the locking fastener 336 is in the second adjustment position, the first connecting member 301 and the second connecting member 302 can rotate relative to each other, and the connecting part 30 is in an unlocked state.
[0134] Furthermore, in Embodiment 3, the locking fastener 336 also forms a first stop portion 3311 at the end of the anti-rotation mating section 3362 that is relatively far from the optical axis section 3363. The outer diameter of the first stop portion 3311 is larger than the inner diameter of the first through hole 312, and it can abut against the first stop portion 3311. The first adjusting unit 303 also includes a pressing member 337, which is a disc-shaped element and is fixed to the end of the optical axis section 3363 that is relatively far from the anti-rotation mating section 3362 by the locking connector 339. The outer diameter of the pressing member 337 is larger than the inner diameter of the first through hole 312.
[0135] With this configuration, the pressing member 337 can cooperate with the first stop part 3311 to ensure that the locking member 336 is always in the state of passing through the first through hole 312 and the second through hole 322, thus preventing the locking member 336 from detaching from the first connector 301 and the second connector 302 and being lost.
[0136] Furthermore, the first adjustment unit 303 also includes a third elastic element 338. One end of the third elastic element 338 abuts against the inner side wall of the pressing member 337 facing the locking member 336, and the other end abuts against the first anti-rotation part 31. When the first adjustment member 332 is in the first adjustment position, the third elastic element 338 is in a state of compression deformation. Therefore, the third elastic element 338 can store elastic potential energy and has the tendency to apply an elastic thrust to the pressing member 337, driving the locking member 336 to move, so that the anti-rotation mating section 3362 simultaneously passes through the first through hole 312 and the second through hole 322, and the fifth tooth group 3361 tends to engage with the third tooth group 3121 and the fourth tooth group 3221 simultaneously.
[0137] Preferably, in Embodiment 3, the third elastic element 338 is a telescopic spring sleeved on the locking connector 339, or sleeved on the locking connector 339 and the optical shaft section 3363. Furthermore, one of the first anti-rotation portions 31 is provided with a pressing groove 314 for accommodating the pressing element 337 and the third elastic element 338. The pressing groove 314 also forms a pressing movement space in the axial direction of the locking element 336, so that after the user applies pressure to the pressing element 337, the pressing element 337 is entirely accommodated within the pressing groove 314, and the third elastic element 338 remains within the pressing groove 314 during the pressing process. When the locking element 336 is in the first adjustment position, the first stop portion 3311 abuts against the other first anti-rotation portion 31, and the pressing element 337 is not higher than the opening edge of the pressing groove 314.
[0138] It is understood that in other embodiments, the anti-rotation fitting section 3362 can also be configured as an external prism structure, and the inner walls of the first through hole 312 and the second through hole 322 can be configured as internal prism surfaces adapted to the anti-rotation fitting section 3362. The movement of the locking fastener 336 within the first through hole 312 and the second through hole 322 can also fix or unlock the anti-rotation of the first anti-rotation part 31 and the second anti-rotation part 32. In this case, the edge of the anti-rotation fitting section 3362 is equivalent to the tooth-shaped rib of the fifth tooth group 3361.
[0139] The decoration tool 100 provided in Embodiment 3 allows the user to drive the locking fastener 336 axially by pressing, thereby releasing the anti-rotation engagement state between the anti-rotation engagement section 3362 and the first anti-rotation part 31 or the second anti-rotation part 32. By releasing the pressure applied to the pressing member 337, the locking fastener 336 is reset under the action of the third elastic member 338, and the anti-rotation engagement section 3362 is fixed to the first anti-rotation part 31 and the second anti-rotation part 32 again, so as to switch the locking and unlocking states of the connecting part 30. In addition, the anti-rotation engagement section 3362 is engaged with the first through hole 312 and the second through hole 322 by teeth, which significantly improves the load-bearing performance of the gripping part 20 and the working part 10 in the mutually locked state, and the first connecting member 301 and the second connecting member 302 are not easy to slip off relative to each other.
[0140] The decorating tool 100 provided by this invention forms an adjustable structure between the working part 10 and the holding part 20 by providing a connecting part 30. The user can rotate the holding part 20 to a position relatively close to the working part 10 to transform the decorating tool 100 into a storage form, making the overall shape of the decorating tool 100 more compact and regular. In its storage form, the decorating tool 100 can be stored orderly, occupying less storage space; it also avoids interference between the holding parts 20 of multiple sets of decorating tools 100, which is beneficial for increasing the maximum carrying capacity of multiple sets of decorating tools 100 in a single centralized transport. Furthermore, it can meet the needs of adjusting the relative position and angle between the holding part 20 and the working part 10 in certain work situations, expanding the applicability of the decorating tool 100.
[0141] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0142] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
