Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of screw disassembly and assembly, and in particular, to a screw disassembly and assembly tool. Background Art

[0002] A screw is a metal product used to fasten or connect objects, usually in a spiral shape.

[0003] The head of the screw has a slot, which is usually a slotted slot, a cross slot or a hexagonal slot, etc. When using screws to fix or connect objects, matching disassembly and assembly tools are required, such as a slotted screwdriver, a cross screwdriver or an Allen wrench, etc. Among them, there are many styles of Allen wrenches, for example, a T-shaped Allen wrench, which usually includes a handle and a hexagonal wrench. The hexagonal wrench is fixedly connected to the handle, and the hexagonal wrench and the handle cooperate to form a T-shaped structure. When using it, the user holds the handle and rotates the handle around the length direction of the hexagonal wrench, thereby driving the hexagonal wrench to rotate to tighten or loosen the screw.

[0004] However, the method of disassembling and assembling screws by holding and turning the handle of the T-shaped hexagonal wrench to drive the hexagonal wrench to rotate is not convenient to operate and has low efficiency. Utility Model Content

[0005] An embodiment of the present application provides a screw disassembling and installing tool to solve the technical problem that the method of disassembling and installing screws by holding and turning the handle of a T-shaped hexagonal wrench to drive the hexagonal wrench to rotate is not convenient to operate and has low efficiency.

[0008] The first working part is connected to the handle, and an end of the first working part facing away from the handle is configured to cooperate with a slot of a screw head;

[0009] The operating part has an operating state and a storage state, and the operating part includes a first operating rod, the first operating rod is connected to a side of the handle away from the first working part, and the first operating rod can rotate between at least a first position and a second position;

[0010] The operating part is configured such that in the operating state, the first operating lever is located at the first position, and rotating the first operating lever drives the first working part to rotate; when the operating part is transferred from the operating state to the storage state, the first operating lever rotates from the first position toward the direction close to the handle and rotates to the second position.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1

[0056] like Figure 1 and Figure 2 As shown, the screw disassembly tool provided in this embodiment includes a handle 100, a first working part 300 and an operating part. The first working part 300 is connected to the handle 100, and the end of the first working part 300 away from the handle 100 is configured to cooperate with the slot of the screw head, that is, the first working part 300 is used to cooperate with the slot of the screw head so that the screw disassembly tool tightens or loosens the bolt. Exemplarily, the structure of the end of the first working part 300 away from the handle 100 can be a straight-shaped structure, a cross-shaped structure, a plum-shaped structure, a hexagonal flat-head structure or a hexagonal round-head structure, etc., that is, the first working part 300 can be a straight-shaped screwdriver head, a cross-shaped screwdriver head, a plum-shaped screwdriver head, a hexagonal flat-head screwdriver head or a hexagonal round-head screwdriver head, etc.

[0057] Exemplarily, the first working portion 300 and the handle 100 are combined to form a T-shaped structure or an L-shaped structure.

[0058] In this embodiment, the operating part has an operating state and a storage state, and the operating part includes a first operating rod 200, the first operating rod 200 is connected to the side of the handle 100 away from the first working part 300, and the first operating rod 200 can at least rotate between a first position and a second position. That is, the first operating rod 200 can rotate from the first position to the second position, or from the second position to the first position, and when the first operating rod 200 rotates from the first position to the second position, the first operating rod 200 can also continue to rotate forward, and a first limiting mechanism (exemplarily, the first limiting mechanism can be the side wall of the accommodating groove 110 described below) can also be set to prevent the first operating rod 200 from continuing to rotate forward. Similarly, when the first operating rod 200 rotates from the second position to the first position, the first operating rod 200 can continue to rotate forward, and a second limiting mechanism (exemplarily, the second limiting mechanism can be the bottom surface of the accommodating groove 110 described below) can also be set to prevent the first operating rod 200 from continuing to rotate forward. Whether the first operating lever 200 continues to rotate after rotating from the first position to the second position, and whether the first operating lever 200 continues to rotate after rotating from the second position to the first position are not specifically limited here.

[0059] In this embodiment, the operating part is configured such that in the operating state, the first operating rod 200 is located at the first position, and the first operating rod 200 is rotated to drive the first working part 300 to rotate; when the operating part is transferred from the operating state to the storage state, the first operating rod 200 is rotated from the first position to the direction close to the handle 100, and rotated to the second position. That is to say, when the operating part is in the storage state, the first operating rod 200 is located at the second position, and the user can hold the handle 100 and twist it hard to loosen or tighten the screw. When the first operating rod 200 is rotated to the second position, the first operating rod 200 deflects to one side, so that when the user holds the handle 100, the end of the first operating rod 200 that is away from the handle 100 and is rotatably connected to the handle 100 will not be against the palm of the user, thereby increasing the comfort of the user when holding the handle 100.

[0060] When the screw disassembling tool provided in this embodiment is in use, since a large force is required in the initial stage of loosening the screw or the terminal stage of tightening the screw, the user can hold the handle 100 and twist it hard to loosen the screw or tighten the screw. After the screw is loosened in the initial stage, the force required to remove the screw is smaller. At this time, the first operating rod 200 is rotated to the first position to put the operating part in the operating state. At this time, the first operating rod 200 is twisted to drive the first working part 300 to rotate, so that the screw can be removed quickly, thereby improving the efficiency of screw removal. Similarly, when installing the screws, the force required to tighten the screws in the initial stage is relatively small. At this time, the first operating rod 200 can be rotated to the first position, and the first operating rod 200 can be twisted to drive the first working part 300 to rotate, so as to quickly tighten the screws and improve the tightening efficiency of the screws. In the terminal stage of tightening the screws, a larger force is required. At this time, the first operating rod 200 is rotated to the second position so that the operating part is in the storage state. The user holds the handle 100 and twists it hard to tighten the screws. The setting of the first operating rod 200 enables the user to tighten or loosen the screws quickly and conveniently, thereby improving the user's efficiency in tightening or loosening the screws.

[0061] In some embodiments of the present application, when the first operating rod 200 is rotated to the first position, the length direction of the first operating rod 200 is aligned with the axial direction of the first working portion 300 (eg, Figure 1, when the first operating rod 200 is rotated to the second position, the angle between the length direction of the first operating rod 200 and the axial direction of the first working part 300 is 45°-150°. Exemplarily, when the first operating rod 200 is rotated to the second position, the angle between the length direction of the first operating rod 200 and the axial direction of the first working part 300 is 45°, 60°, 80°, 90°, 100° or 150°. That is to say, when the first operating rod 200 is rotated to the first position, the angle between the length direction of the first operating rod 200 and the axial direction of the first working part 300 is 0°, and when the first operating rod 200 is rotated to the second position, the first operating rod 200 is rotated clockwise or counterclockwise, and the first operating rod 200 is rotated in the direction close to the handle 100, thereby causing the vertical first operating rod 200 to deflect and tilt to one side, and then when the user holds the handle 100, the end of the first operating rod 200 that is away from the end thereof that is rotatably connected to the handle 100 will not rest against the palm of the user, thereby increasing the comfort of the user when holding the handle 100.

[0062] It should be noted that the length direction of the first operating rod 200 and the axial direction of the first working part 300 are the same, which means that the length direction of the first operating rod 200 and the axial direction of the first working part 300 are in the same direction, the length direction of the first operating rod 200 and the axial direction of the first working part 300 are parallel, and the direction is defined to be the same. That is to say, if the direction of the first working part 300 is defined as from the end of the first working part 300 away from the handle 100 to the end of the handle 100, then the length direction of the first operating rod 200 is from the end of the first operating rod 200 that is rotatably connected to the handle 100 to the end of the first operating rod 200 away from the handle 100.

[0063] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present application, a receiving groove 110 is provided on the side of the handle 100 away from the first working portion 300. The first end of the first operating rod 200 is rotatably connected to the side wall of the receiving groove 110, and when the first operating rod 200 is rotated to the second position, the first operating rod 200 sinks into the receiving groove 110. In other words, Figure 1 As shown, when the first operating rod 200 rotates to the first position, the first operating rod 200 is vertically upward, that is, the length direction of the first operating rod 200 is the same as the axial direction of the first working part 300; Figure 2 As shown, when the first operating rod 200 rotates to the second position, the first operating rod 200 rotates to one side and enters the accommodating groove 110, so that when the user holds the handle 100, the first operating rod 200 will not interfere with the user's holding of the handle 100, thereby increasing the comfort of the user when holding the handle 100.

[0064] For example, when the first operating rod 200 is sunk into the receiving groove 110 and the first operating rod 200 is rotated to the second position, the angle between the length direction of the first operating rod 200 and the axial direction of the first working part 300 is about 90°.

[0065] It should be noted that the receiving groove 110 of the embodiment of the present application is not limited to Figure 3 The structure in Figure 3 On the basis of the structure shown, the receiving groove 110 extends to the left, that is, the first end of the first operating rod 200 is rotatably connected to the side wall of the middle part of the receiving groove 110. When the first operating rod 200 is in a vertical state, the first operating rod 200 is in the first position, that is, the operating part is in the operating state, and the first operating rod 200 can be rotated to the right from the first position to sink into the receiving groove 110 at the right part of the rotation connection between the first operating rod 200 and the side wall of the receiving groove 110. The first operating rod 200 can also be rotated to the left from the first position to sink into the receiving groove 110 at the left part of the rotation connection between the first operating rod 200 and the side wall of the receiving groove 110. The second position can be the position where the first operating rod 200 is rotated to the right and sunk into the receiving groove 110, or it can be the position where the first operating rod 200 is rotated to the left and sunk into the receiving groove 110.

[0066] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present application, the accommodating groove 110 includes a connected transverse groove 111 and a longitudinal groove 112, the transverse groove 111 and the longitudinal groove 112 form a T-shaped structure, and the longitudinal groove 112 is in the length direction of the handle 100 (such as Figure 1 The first operating rod 200 includes a connecting edge 210 and an operating edge 220 connected to each other, and the operating edge 220 and the connecting edge 210 form a T-shaped structure. The connecting edge 210 is located in the transverse groove 111 and is rotatably connected to the side wall of the transverse groove 111. When the first operating rod 200 rotates to the second position, the operating edge 220 rotates into the longitudinal groove 112. In this embodiment, the length direction of the first operating rod 200 is the length direction of the operating edge.

[0067] In order to prevent slipping when rotating the operating edge 220, an anti-slip structure is provided on the side of the operating edge 220. For example, in the direction around the length direction of the operating edge, the side of the operating edge 220 is provided with multiple raised edges at intervals, and the multiple raised edges form an anti-slip structure. Of course, the anti-slip structure can also be other structures, which are not specifically limited here.

[0068] In some embodiments of the present application, in order to facilitate the rotation out of the first operating rod 200 rotated into the receiving groove 110, a clearance groove connected to the receiving groove 110 is provided on the side of the handle 100 away from the first working part 300, and the clearance groove is located at the end of the receiving groove 110 away from the rotational connection with the first operating rod 200, and the clearance groove is configured to make way for the user's finger when the first operating rod 200 is rotated into the receiving groove 110, so that the user can pull the first operating rod 200 out of the receiving groove 110. In other words, the clearance groove provides a clearance space for the user to insert his finger to press the first operating rod 200, so that the user can pull the first operating rod 200 out of the receiving groove 110.

[0069] like Figure 4 As shown, in some embodiments of the present application, in order to facilitate the user to pick the first operating rod 200 out of the accommodating groove 110, the end face of the second end of the first operating rod 200 is provided with a hand-picking protrusion 221, and the second end of the first operating rod 200 and the first end of the first operating rod 200 are two opposite ends of the first operating rod 200.

[0070] In some embodiments of the present application, the bottom surface of the recess is an inclined surface 120, and the inclined surface 120 is inclined toward the bottom of the receiving groove 110. Exemplarily, one end of the inclined surface 120 close to the receiving groove 110 is located in the middle of the side wall of the receiving groove 110, and the angle between the inclined surface 120 and the plane where the side wall of the receiving groove 110 is located is 45°-85°.

[0071] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the screw disassembly tool also includes a second working part 400, the second working part 400 is connected to the handle 100, and the second working part 400 extends from one end of the handle 100 in the length direction, and the end of the second working part 400 extending from the handle 100 is configured to cooperate with the slot of the screw head. The provision of the second working part 400 makes the screw disassembly tool more flexible to use. Exemplarily, the length of the portion of the second working part 400 extending from the handle 100 is less than the length of the portion of the first working part 300 extending from the handle 100. The smaller length of the portion of the second working part 400 extending from the handle 100 can apply more force, can make the screw tightened more tightly, and can more easily loosen the screw in the initial stage.

[0072] In some embodiments of the present application, illustratively, the structure of the end of the first working part 300 away from the handle 100 is different from the structure of the end of the second working part 400 away from the handle 100. Exemplarily, the end of the first working part 300 away from the handle 100 is a cross-shaped structure, and the end of the second working part 400 away from the handle 100 is a hexagonal flat head structure, or the end of the first working part 300 away from the handle 100 is a hexagonal round head structure, and the end of the second working part 400 away from the handle 100 is a hexagonal flat head structure, etc. Of course, the structure of the end of the first working part 300 away from the handle 100 and the structure of the end of the second working part 400 away from the handle 100 can also be the same. Embodiment 2

[0073] like Figure 5 As shown, in this embodiment, the operating portion includes a first operating rod 200 and a second operating rod 500. The first operating rod 200 is connected to the side of the handle 100 away from the first working portion 300, and the first operating rod 200 can at least rotate between a first position and a second position. The second operating rod 500 is connected to the side of the handle 100 away from the first working portion 300, and the second operating rod 500 can at least rotate between a third position and a fourth position. The operating portion is configured such that in the operating state, the first operating rod 200 is located at the first position, and the second operating rod 500 is located at the third position. The first operating rod 200 and the second operating rod 500 are rotated to drive the first working portion 300 to rotate; when the operating portion is transferred from the operating state to the storage state, the second operating rod 500 rotates from the third position to the direction close to the handle 100, and rotates to the fourth position. The direction in which the first operating rod 200 rotates from the first position to the second position is different from the direction in which the second operating rod 500 rotates from the third position to the fourth position. In other words, Figure 5 As shown, when the operating part is in the operating state, the first operating rod 200 is located at the first position, and the second operating rod 500 is located at the third position. The first operating rod 200 and the second operating rod 500 serve as the operating part of the screw disassembling tool. When the force required for disassembling the screw is small, the operating part can be rotated to drive the first working part 300 to rotate. At the initial stage of loosening the screw or the terminal stage of tightening the screw, the force required for disassembling the screw is large. At this time, the first operating rod 200 is rotated to the second position, and the second operating rod 500 is rotated to the fourth position. As a result, the first operating rod 200 and the second operating rod 500 are deflected to both sides, and the user holds the handle 100 and twists it hard to tighten the screw, thereby increasing the comfort of the user when holding the handle 100.

[0074] In some embodiments, when the second operating rod 500 is rotated to the third position, the length direction of the second operating rod 500 is the same as the axial direction of the first working part 300, that is, when the operating part is in the operating state, the first operating rod 200 is located at the first position, the second operating rod 500 is located at the second position, and the length direction of the first operating rod 200 (for example, Figure 5 ) and the length direction of the second operating rod 500 (eg, Figure 5 The first operating rod 200 and the second operating rod 500 are the same as the Y direction in the figure. This setting facilitates the user to quickly twist the first operating rod 200 and the second operating rod 500, thereby improving the efficiency of screw disassembly and installation. When the second operating rod 500 is rotated to the second position, the angle between the length direction of the second operating rod 500 and the axial direction of the first working part 300 is 45°-150°. Exemplarily, when the second operating rod 500 is rotated to the fourth position, the angle between the length direction of the second operating rod 500 and the axial direction of the first working part 300 is 45°, 60°, 80°, 90°, 100° or 150°. That is to say, when the second operating rod 500 is rotated to the fourth position, the angle between the length direction of the second operating rod 500 and the axial direction of the first working part 300 is 0°. When the second operating rod 500 is rotated to the fourth position, the second operating rod 500 is rotated in the direction away from the first operating rod 200, thereby causing the vertical second operating rod 500 to deflect and tilt to one side. Therefore, when the user holds the handle 100, the end of the second operating rod 500 that is away from the end that is rotatably connected to the handle 100 will not rest against the palm of the user, thereby increasing the comfort of the user when holding the handle 100.

[0075] When the screw disassembly tool provided in this embodiment is used, the user can hold the handle 100 and twist it hard to loosen or tighten the screw in the initial stage of loosening the screw or the terminal stage of tightening the screw. After the screw is loosened in the initial stage, the force required for removing the screw is small. At this time, the first operating rod 200 is rotated to the first position, and the second operating rod 50 is rotated to the third position, so that the operating part is in an operating state. At this time, the operating part composed of the first operating rod 200 and the second operating rod 500 is twisted to drive the first working part 300 to rotate, thereby quickly removing the screw and improving the removal efficiency of the screw. Similarly, when installing the screw, the force required to twist the screw in the initial stage is small. At this time, the first operating rod 200 can be rotated to the first position, the second operating rod 500 can be rotated to the third position, and the operating part composed of the first operating rod 200 and the second operating rod 500 can be twisted to drive the first working part 300 to rotate, so as to quickly tighten the screw and improve the tightening efficiency of the screw. At the beginning stage of loosening the screw or the end stage of tightening the screw, a large force is required. At this time, the first operating rod 200 is rotated to the second position, and the second operating rod 500 is rotated to the fourth position, so that the operating part is in the storage state. The user holds the handle 100 and twists it hard to tighten or loosen the screw.

[0076] In some embodiments, when the first operating rod 200 is in the first position and the second operating rod 500 is in the third position, the first operating rod 200 is in contact with the second operating rod 500. This position setting enables the user to more quickly and conveniently twist the operating part composed of the first operating rod 200 and the second operating rod 500, thereby driving the first working part 300 to rotate, so as to quickly disassemble and assemble the screws and improve the efficiency of disassembly and assembly of the screws.

[0077] Of course, in other embodiments, when the first operating rod 200 is in the first position and the second operating rod 500 is in the third position, the first operating rod 200 and the second operating rod 500 may be opposite to each other with a gap therebetween, or the first operating rod 200 and the second operating rod 500 may form a V-shaped structure, etc.

[0078] like Figure 5 As shown, in this embodiment, a receiving groove 110 is provided on the side of the handle 100 away from the first working part 300. The first end of the first operating rod 200 is rotatably connected to the side wall of the receiving groove 110 in the middle of the length direction. When the first operating rod 200 is rotated to the second position, the first operating rod 200 sinks into the receiving groove 110 located on the side of the first operating rod 200 away from the second operating rod 500. The first end of the second operating rod 500 is rotatably connected to the side wall of the receiving groove 110 in the middle of the length direction. When the second operating rod 500 is rotated to the fourth position, the second operating rod 500 sinks into the receiving groove 110 located on the side of the second operating rod 500 away from the first operating rod 200. In other words, Figure 5 As shown, in the storage state, the first operating rod 200 and the second operating rod 500 rotate to the two sides to the corresponding side of the receiving groove 110 and sink into the receiving groove 110. The operating part is divided into two parts, which are rotated to the two sides and sunk into the receiving groove 110. This setting can reduce the depth of the receiving groove 110.
