Description

Technical Field

[0001] This utility model relates to an electric tool, and more particularly to an electric tool with a position adjustment function. Background Technology

[0002] Power tools, such as angle grinders, often require cutting or grinding at different angles. Many users rotate the entire power tool to accommodate different working angles, which can become inconvenient or uncomfortable to operate over time.

[0003] Currently, one solution involves designing the housing with the tool head and the outer shell of the handheld part as two detachable components connected by screws. When the working angle of the tool head needs to be changed, the screws can be removed to rotate the housing with the tool head attached, thus altering the working posture. However, this method is cumbersome, requiring the screws to be removed and reassembled for each adjustment, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a power tool that can conveniently adjust the working angle of the tool head while ensuring operational safety, and greatly improve the user experience.

[0005] To achieve the above objectives, this utility model proposes a power tool having a housing, the housing comprising at least a first housing portion and a second housing portion. The first housing portion has a gripping area, and the gripping area is provided with a power switch button. Action of the power switch button triggers a power switch located inside the housing. The second housing portion is connected to the tool head of the power tool. The second housing portion is rotatably connected to the first housing portion. The power tool further includes:

[0006] An adjustment locking element is provided in the gripping area of ​​the first housing portion. The adjustment locking element is configured to switch between an adjustment position and a locking position. In the locking position, the adjustment locking element engages with the second housing portion to prevent the second housing portion from rotating relative to the first housing portion about a rotation axis. In the adjustment position, the adjustment locking element disengages from the second housing portion to allow the second housing portion to rotate relative to the first housing portion about a rotation axis.

[0007] An interlocking structure is provided in association with the adjustment locking element and the power switch button of the power tool, so that when the adjustment locking element is in the adjustment position, the power switch button is locked in the off position, and when the power switch button is in the power on position, the adjustment locking element is locked in the locking position.

[0008] The adjustment locking element and the power switch button are located on two mutually perpendicular surfaces of the grip area.

[0009] Furthermore, in the power tool described in this utility model, the adjustment locking element is located on the side of the grip area, and the power switch button is located on the bottom surface of the grip area.

[0010] Furthermore, in the power tool described in this utility model, the axial end face of the connecting side of the second housing portion has a radially inwardly extending stop portion, which is configured to prevent the second housing portion from continuing to rotate relative to the first housing portion.

[0011] Furthermore, the power tool of this utility model also includes a reset element, which applies an elastic force to the adjustment and locking element to reset it from the adjustment position to the locking position.

[0012] Furthermore, in the power tool described in this utility model, the first housing portion and the second housing portion are rotatably connected by a circumferentially extending circumferential groove and a matching circumferential flange.

[0013] Furthermore, in the power tool described in this utility model, the adjustment locking element includes a button, which is configured to move linearly relative to the first housing portion in a direction toward or away from the interior of the first housing portion, so as to switch between an adjustment position and a locking position.

[0014] Furthermore, in the power tool described in this utility model, the adjusting locking element is located on the side of the first housing portion.

[0015] Furthermore, the power tool of this utility model also includes a partition disposed within the first housing portion to separate at least a first cavity and a second cavity within the first housing portion. The adjustment locking element is disposed within the first cavity, and the second cavity is at least used to accommodate a cable.

[0016] Furthermore, in the power tool described in this utility model, the first side of the partition and the first housing portion form the first cavity, and the second side of the partition opposite to the first side and the first housing portion form the second cavity, and a cable tray is provided on the second side.

[0017] Furthermore, in the power tool described in this utility model, the partition is provided with a guide hole, which is configured to provide guidance for the switching action of the adjusting locking element between the adjusting position and the locking position.

[0018] Furthermore, the power tool described in this utility model also includes an interlocking structure, which is associated with the adjustment locking element and the power switch of the power tool, so that when the adjustment locking element is in the adjustment position, the power switch is locked in the off state, and when the power switch is in the power-on state, the adjustment locking element is locked in the locking position.

[0019] Furthermore, in the power tool described in this utility model, the interlocking structure includes:

[0020] The second protrusion extending from the self-adjusting locking element;

[0021] A lever is rotatable about its axis in a first rotational direction or in a second rotational direction opposite to the first rotational direction; rotation of the lever in the first rotational direction enables the energized switch to switch from an off state to an on state.

[0022] A push rod, which is used to connect to the power switch button of a power tool, the movement of the push rod being related to the rotation of the lever;

[0023] Specifically, when the adjusting locking element is in the adjusting position, the second protrusion interferes with the push rod to prevent the push rod from pushing the lever to rotate around its axis in the first rotation direction; when the power switch button is in the position that enables the power switch to be energized, the push rod interferes with the second protrusion to prevent the adjusting locking element from switching from the locking position to the adjusting position.

[0024] Furthermore, in the power tool described in this utility model, the lever has a first arm for contacting an energized switch and a second arm for contacting a push rod. Rotation of the lever in a first rotation direction enables the first arm to push the energized switch, thereby switching the switch contacts of the energized switch from a non-contact state to a contact state, and switching the energized switch from an off state to an on state.

[0025] Furthermore, in the power tool described in this utility model, when the adjusting locking element is in the adjusting position, the second protrusion interferes with the first part of the push rod to prevent the push rod from pushing the lever to rotate around its axis in the first rotation direction; when the power switch is in the energized state, the second part of the push rod interferes with the second protrusion to prevent the adjusting locking element from switching from the locking position to the adjusting position.

[0026] Furthermore, the power tools described in this utility model include an angle grinder.

[0027] The power tool described in this utility model allows the first housing part and the second housing part to easily rotate relative to each other or lock the relative rotation between them by switching and adjusting the position of the locking element, thereby conveniently adjusting the position or working angle of the tool head connected to the second housing part.

[0028] Furthermore, this invention further ensures safety when adjusting posture by setting an interlocking structure.

[0029] The adjustment locking element and the power switch button of the power tool described in this utility model are located on two mutually perpendicular surfaces of the grip area. This allows the thumb to naturally rest on the adjustment locking element when the operator's hand is on the grip area and all fingers except the thumb are placed on the power switch button to control the power tool's on / off state. This makes the operation more convenient, the grip more comfortable, and provides an excellent user experience. Attached Figure Description

[0046] Figure 17 The power tool is shown exemplarily in three different positions. Detailed Implementation

[0047] The electric tools described in this utility model will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, such explanation and description do not constitute an undue limitation on the technical solution of this utility model.

[0048] Power tools, such as angle grinders, often require operation at different angles, such as cutting or grinding. In such cases, many users rotate the entire power tool body to accommodate different tool head working angles, which can be inconvenient.

[0049] Currently, one solution involves designing the housing with the tool head and the outer shell with the grip as two detachable parts connected by screws. When the working angle of the tool head needs to be changed, the two housing parts can be disassembled by removing the screws, then one housing part can be rotated relative to the other by the desired angle to change the working posture. The screws are then reinstalled to secure the two housing parts together. However, this method is cumbersome, requiring screw removal and reassembly for each adjustment of the working posture, resulting in a poor user experience.

[0050] Based on this, in one embodiment of the present invention, a power tool is provided that can conveniently adjust the working angle of the tool head while ensuring operational safety, and greatly improve the user experience.

[0051] Figure 1 This diagram shows the external three-dimensional structure of the power tool according to one embodiment of the present invention.

[0052] like Figure 1 As shown, in this embodiment, the power tool can be an angle grinder. The power tool has a housing, which may include at least a first housing portion 100 and a second housing portion 200. When the operator needs to operate the power tool, their hand grips the gripping area H of the first housing portion. A power switch button 900 is provided in the gripping area of ​​the first housing portion. Action of the power switch button 900 triggers a power switch located inside the housing, turning the power tool on or off. The second housing portion 200 is connected to the tool head 400 of the power tool. The second housing portion 200 is rotatably connected to the first housing portion 100, and from the outside, the second housing portion 200 and the first housing portion 100 are joined at a seam P.

[0053] Furthermore, an adjustment locking element 300 is provided on the gripping area H of the first housing portion. The position of the adjustment locking element 300 on the first housing portion 100 can be switched between an adjustment position and a locking position. Figure 2 and Figure 3 The locking position shown has an adjusting locking element 300 on the first housing part 100 engaging with the second housing part 200, thereby preventing the second housing part 200 from rotating relative to the first housing part 100 about the rotation axis Q.

[0054] In such Figure 4 and Figure 5The adjustment station shown allows the locking element 300 to disengage from the second housing portion 200, enabling the second housing portion 200 to rotate relative to the first housing portion 100 around the rotation axis Q, thereby adjusting the position of the tool head 400.

[0055] In addition, to further improve the safety of using power tools, such as Figure 6 As shown, the power tool may also include an interlocking structure 700 associated with the power switch button 900, such that when the adjustment locking element 300 is in the adjustment position, the power switch button 900 is locked in a position that turns the power switch off, for example, it cannot be pressed in the height direction; and when the power switch button 900 is in a position that turns the power switch on, the adjustment locking element is locked in a locking position, for example, it cannot be pressed.

[0056] The adjustment locking element 300 and the power switch button 900 are located on two mutually perpendicular surfaces of the grip area H.

[0057] It should be noted that since this utility model relates to an electric tool whose outer shell cannot be an absolute geometric cube in actual production, the above-mentioned "mutually perpendicular" is not absolute perpendicular in a geometric sense, but rather perpendicular, basically perpendicular, or approximately perpendicular. This means that the adjusting locking element 300 and the power switch button 900 are not located on two opposite surfaces of the outer shell, such as the top and bottom surfaces or two opposite sides, but are located on two basically perpendicular intersecting surfaces.

[0058] With this configuration, when the operator's hand is on the grip area H, and when all fingers except the thumb are placed on the power switch button 900 to control the power tool's on and off, the thumb will naturally be on the adjustment locking element 300, making the operator's operation convenient, the grip more comfortable, and providing an excellent user experience.

[0059] In some more specific implementations, such as Figure 1 As shown, the adjustment locking element 300 can be located on the side 101 of the first housing portion, and the power switch button 900 can be located on the bottom surface 102 of the power tool housing. In some embodiments, the side surface can be understood as the area between the output shaft of the power tool head and the motor shaft of the power tool (i.e., the axis of the machine body). Figure 1 The plane formed by Q is parallel to the plane.

[0060] In some more specific embodiments, adjusting the locking element may include, for example: Figure 1 The button shown is configured to be radially inward relative to the first housing portion toward the interior of the first housing portion (e.g., pointing to...). Figure 1The adjustment locking element 300 can be moved linearly in a radially outward direction (as shown in the paper) away from the interior of the first housing portion to switch between the adjustment position and the locking position. In this case, the operator can press the adjustment locking element 300 to switch it between the adjustment position and the locking position. In some more specific embodiments, the adjustment locking element is pressed, i.e., linear movement in a radially inward direction achieves the switch from the locking position to the adjustment position.

[0061] Of course, in other, more specific embodiments, the operator may also push the adjusting locking element 300 along the axial direction of the rotation axis Q of the power tool housing to switch it between the adjusting position and the locking position.

[0062] In some other, more specific embodiments, the operator may also cause the adjusting locking element to rotate about a pivot to switch between the adjusting position and the locking position.

[0063] Figure 7 and Figure 8 A three-dimensional structural diagram of the adjusting locking element in one embodiment is shown.

[0064] like Figure 7 and Figure 8 As shown, the adjusting locking element 300 has a first protrusion 301. Adapted thereto, such as... Figure 2 and Figure 4 As shown, a plurality of locking grooves 201 distributed along the circumferential direction are provided on the axial end face 210 of the connection side of the second housing part 200. The locking grooves 201 are used to engage with the first protrusion 301, thereby locking the rotation of the second housing part 200 relative to the first housing part 100 in the engaged state.

[0065] Under the adjustment of workstation, such as Figure 4 and Figure 5 As shown, the first protrusion 301 moves radially inward linearly, thereby disengaging from the locking groove 201. At this time, the operator can apply force to make the second housing part 200 rotate around the rotation axis Q of the first housing part 100 by the required angle. Since the adjusting locking element 300 is provided on the first housing part 100, the second housing part 200 also rotates around the adjusting locking element 300 by the required angle during this process. At this time, the first protrusion 301 falls into another locking groove 201 again, thereby locking the second housing part 200 relative to the first housing part 100 at the current position angle.

[0066] In some more specific embodiments, the angle by which the second housing portion 200 rotates relative to the first housing portion 100 about the rotation axis Q can be controlled by setting the number of locking slots distributed along the circumferential direction.

[0067] like Figure 2 , Figure 4 and Figure 9 As shown, in some embodiments, in order to limit the travel of the second housing portion relative to the first housing portion by the angle of rotation, a radially inwardly extending stop portion 202 is also provided on the axial end face 210 of the connecting side of the second housing portion.

[0068] In some more specific embodiments, two stops are provided to limit the travel of the second housing portion 200 relative to the first housing portion 100 in both rotational directions. In some more specific embodiments, when the stop portion 202 interferes with the first protrusion 301, it prevents the second housing portion from continuing to rotate relative to the first housing portion.

[0069] In a more specific implementation, such as Figure 9 As shown, three locking slots 201 are evenly distributed along a 180° arc in the circumferential direction. If the locking element is defined to be located at... Figure 8 When the power tool (e.g., an angle grinder) is in the locking slot at the bottom, its position is 0°. When it rotates clockwise to the left locking slot, its position can be considered -90°, and the left stop limits the further rotation of the adjusting locking element. Similarly, when the adjusting locking element rotates counterclockwise from the power tool's 0° position to the right locking slot, its position can be considered 90°, and the right stop limits the further rotation of the adjusting locking element.

[0070] like Figure 6 As shown, in some embodiments, the first housing portion 100 and the second housing portion 200 are rotatably connected by a circumferentially extending circumferential groove 501 and a matching circumferential flange 502, thereby achieving a relatively fixed connection in the axial direction and a relatively movable connection in the circumferential direction.

[0071] like Figure 6 As shown, in some embodiments, a reset element 600 may also be provided, which applies an elastic force to the adjustment locking element to reset it from the adjustment position to the locking position or applies a reset force to reset it from the locking position to the adjustment position.

[0072] In some more specific embodiments, when the operator presses the adjusting locking element, causing it to move linearly in the radially inward direction to switch from the locking position to the adjusting position, the elastic force applied by the reset element 600 resets the adjusting locking element from the adjusting position to the locking position. With the cooperation of the reset element 600, when the working angle of the tool head needs to be adjusted, the operator presses the adjusting locking element, and its first protrusion 301 moves linearly in the radially inward direction, thereby disengaging from the locking groove 201. At this time, the operator can apply force to make the second housing part 200 rotate relative to the first housing part 100 around the rotation axis Q by the required angle. During this process, the operator can release the adjusting locking element. Under the pre-tightening force of the reset element, during the angle adjustment process, the first protrusion abuts against the inner wall of the connecting side of the second housing part and rotates relative to the second housing part until it rotates to another locking groove. Then, under the elastic force of the reset element, the first protrusion 301 falls into the other locking groove 201.

[0073] In some more specific embodiments, the reset element 600 may include a helical spring.

[0074] Figures 10-13 The interlocking structure of the power tool described in this utility model is shown in one embodiment.

[0075] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in some specific embodiments, the interlocking structure may include: a second protrusion 302 extending from the self-adjusting locking element 300; a lever 701, which is rotatable about its axis 702 in a first rotation direction R1 or in a second rotation direction opposite to the first rotation direction; the rotation of the lever 701 in the first rotation direction R1 enables the energizer switch 800 to switch from an off state to an on state; and a push rod 703, which is connected to the energizer switch button 900 of the power tool, and the action of the push rod 703 is associated with the rotation of the lever 701.

[0076] When the adjusting locking element 300 switches from the locking position to the adjusting position, the second protrusion 302 is pressed radially inward along with the adjusting locking element 300 (e.g., Figure 12 and 13 The middle finger extends outwards from the paper, thus... Figure 12 and Figure 13As shown, interference with push rod 703 blocks its further movement path, thus preventing push rod 703 from pushing lever 701 to rotate around its axis 702 in the first rotation direction R1. With this configuration, when the power tool enters the position adjustment state, the power switch button 900 cannot be pressed, preventing the power switch from being energized, thereby avoiding accidental triggering and ensuring the safety of the power tool.

[0077] like Figure 10 and Figure 11 As shown, when the power switch 800 is energized, the push rod 703 interferes with the second protrusion 302, blocking the movement path of the adjustment locking element from the locking position to the adjustment position, thus preventing the adjustment locking element from switching from the locking position to the adjustment position. With this setting, when the power tool is energized, the adjustment locking element 300 cannot be pressed, ensuring the safety of using the power tool.

[0078] In some more specific implementations, such as Figure 11 and Figure 13 As shown, the lever 701 has a first arm 7011 for contacting the energized switch 800 and a second arm 7012 for contacting the push rod. With this arrangement, rotation of the lever in the first rotation direction R1 causes the first arm 7011 to push the energized switch 800, particularly the end of the axially telescopic portion 801 of the energized switch having a bellows-like structure, so that the switch contacts of the energized switch (hidden within the axially telescopic portion 801 and not visible in the figure) switch from a non-contact state to a contact state, thus switching the energized switch from an off state to an on state. For example, as... Figure 10 and Figure 11 As shown, the axial telescopic part 801 is in a compressed state, and its internal switch contacts are in contact, so the energized switch is in an energized state. Figure 12 and Figure 13 As shown, when the axial telescopic part 801 is in a stretched state, the switch contacts inside it are in a non-contact state, and the energized switch is in a closed state.

[0079] In some more specific implementations, such as Figure 12 and Figure 13As shown, when the adjustment locking element 300 is in the adjustment position, the radially inwardly extending second protrusion 302 interferes with the first part 7031 of the push rod, for example, at the top. With this configuration, even if the operator applies an upward pressing force to the power switch button 900, the second protrusion 302 blocks the upward movement path of the push rod 703, preventing the push rod 703 from moving along that path. Therefore, the push rod cannot be pushed to rotate around its axis in the first rotation direction R1, thus locking the power switch 800 in the off state.

[0080] On the other hand, when the power switch 800 is in the energized state, such as Figure 10 and Figure 11 As shown, the second part 7032 of the push rod 703, for example the side, interferes with the second protrusion 302, blocking the movement path of the second protrusion 302 being pressed radially inward, so as to prevent the adjustment locking element from switching from the locking position to the adjustment position.

[0081] In some more specific embodiments, the power switch button 900 can be as follows: Figure 1 The paddle-type button is shown. Of course, in other embodiments, it can also be constructed as a switch with other structures, such as a push-pull switch.

[0082] like Figure 14 As shown, in some embodiments, the power tool may further include a partition 910 disposed within the first housing portion 100 to at least separate a first cavity (obscured by the partition and not visible in the figure) and a second cavity within the first housing portion, an adjustment locking element 300 (obscured by the partition and not visible in the figure) disposed within the first cavity, and the second cavity may be used at least for accommodating cables.

[0083] The cables of power tools, such as stator cables, rotate with the motor housing and cannot be completely fixed like those of ordinary tools. Allowing the cables to move freely within the housing would affect other mechanical mechanisms and pose safety risks. Considering these issues, in some preferred embodiments of this invention, the aforementioned partition 910 is provided, placing the cables and at least the mechanical structure including adjustment and locking elements in two separate cavities to prevent them from interfering with each other.

[0084] like Figure 15 and Figure 16As shown, in some more specific embodiments, the first side 911 of the partition 910 forms a first cavity with the first housing portion 100, and the second side 912 of the partition opposite to the first side forms a second cavity with the first housing portion. A cable tray 913 is provided on the second side 912 via spaced ribs protruding from the second side. In this embodiment, the cable tray 913 further facilitates the orderly arrangement of cables.

[0085] In some more specific embodiments, the partition 910 may also be provided with a guide hole 914 to guide the switching action of the adjusting locking element between the adjusting position and the locking position.

[0086] In addition, the partition can also be used to set the reset element 600.

[0087] Figure 17 The power tool is illustrated in three different positions. It can be seen that the power tool described in this invention allows for convenient adjustment of the tool head's position, and regardless of the tool head's working angle, the adjustment locking element 300 and the power switch button 900 are located on two mutually perpendicular surfaces of the grip area H, thereby significantly improving the user experience.

[0088] In some more specific embodiments, the power tool may include an angle grinder. Of course, in other embodiments, the power tool may also be any other device that requires adjustment of the tool head angle.

[0089] This utility model does not involve improvements to other components of power tools; therefore, the specific structure and usage of power tools will not be described in detail here.

6. The power tool as claimed in claim 1, characterized in that, The first housing portion and the second housing portion are rotatably connected by a circumferentially extending circumferential groove (501) and a matching circumferential flange (502).

7. The power tool as claimed in claim 1, characterized in that, The adjustment locking element includes a button configured to move linearly relative to the first housing portion in a direction toward or away from the interior of the first housing portion, to switch between an adjustment position and a locking position.

8. The power tool as described in any one of claims 1-7, characterized in that, It also includes a partition (910) disposed within the first housing portion to separate at least a first cavity and a second cavity within the first housing portion, wherein the adjustment locking element is disposed within the first cavity and the second cavity is at least used to accommodate a cable.

9. The power tool as claimed in claim 8, characterized in that, The first side (911) of the partition and the first housing portion form the first cavity, and the second side (912) of the partition opposite to the first side and the first housing portion form the second cavity, and a cable tray (913) is provided on the second side.

10. The power tool as claimed in claim 8, characterized in that, The partition plate is provided with a guide hole (914), which is configured to provide guidance for the switching action of the adjusting locking element between the adjusting position and the locking position.

11. The power tool as described in any one of claims 1-7, characterized in that, The interlocking structure includes: The second protrusion (302) extending from the self-adjusting locking element; A lever (701) is rotatable about its axis (702) in a first rotational direction or in a second rotational direction opposite to the first rotational direction; rotation of the lever in the first rotational direction enables the energized switch to switch from an off state to an on state. A push rod (703) is connected to the power switch button (900) of a power tool, and the action of the push rod is related to the rotation of the lever; Specifically, when the adjusting locking element is in the adjusting position, the second protrusion interferes with the push rod to prevent the push rod from pushing the lever to rotate around its axis in the first rotation direction; when the power switch button is in the position that enables the power switch to be energized, the push rod interferes with the second protrusion to prevent the adjusting locking element from switching from the locking position to the adjusting position.

12. The power tool as claimed in claim 11, characterized in that, The lever has a first arm (7011) for contacting an energized switch and a second arm (7012) for contacting a push rod. Rotation of the lever in a first rotation direction causes the first arm to push the energized switch, thereby switching the switch contacts of the energized switch from a non-contact state to a contact state, and switching the energized switch from an off state to an on state.

13. The power tool as claimed in claim 11, characterized in that, When the adjusting locking element is in the adjusting position, the second protrusion interferes with the first part of the push rod to prevent the push rod from pushing the lever to rotate around its axis in the first rotation direction; when the power switch is in the energized state, the second part of the push rod interferes with the second protrusion to prevent the adjusting locking element from switching from the locking position to the adjusting position.

14. The power tool as claimed in claim 1, characterized in that, The power tools include an angle grinder.
