Description

Technical Field

[0001] This application belongs to the field of disassembly and assembly tool technology, and specifically relates to a wrench. Background Technology

[0002] Wrenches are mainly used for removing and installing screws. Currently, to remove and install screws of different sizes, it is necessary to prepare multiple wrenches of different sizes and switch between them to remove and install the appropriate size. However, switching between multiple wrenches can easily lead to the loss of some wrenches. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a wrench that can provide connection parts of different sizes to disassemble and assemble workpieces of different specifications.

[0004] This application provides a wrench for disassembling and assembling various internal angle workpieces of different sizes, including an outer sleeve, an adjusting member, and multiple disassembly / assembly parts. The outer sleeve extends axially and has a disassembly / assembly end and a top end. The outer sleeve is provided with multiple first positioning members. Multiple disassembly / assembly parts are disposed on the outer sleeve and are movable relative to the outer sleeve axially. Each disassembly / assembly part includes a connected moving part and a connecting part. The moving part has a first positioning groove for connecting the first positioning member. Each moving part is axially spaced adjustable from adjacent moving parts. Multiple connecting parts extend axially to the disassembly / assembly end. From the disassembly / assembly end towards the top end, each connecting part is sequentially fitted onto adjacent connecting parts, and the connecting part is used for disassembling and assembling workpieces. The adjusting member is fitted onto the outer sleeve and is movable relative to the outer sleeve, used to drive one disassembly / assembly part to move axially toward the disassembly / assembly end, causing the first positioning member to disengage from the first positioning groove, and the corresponding connecting part to extend out of the disassembly / assembly end.

[0005] In the aforementioned wrench, a suitable disassembly / assembly part is selected based on the specifications of the workpiece to be disassembled or assembled. The selected part is then driven to move axially via an adjusting mechanism, causing the corresponding connecting part to extend from the disassembly / assembly end of the outer sleeve to connect with the workpiece, thereby disassembling or assembling it. When the wrench is applied to the disassembly / assembly of screws, the connecting part extending from the disassembly / assembly end is inserted into the screw, causing it to rotate and thus completing the disassembly or assembly.

[0006] In some embodiments, the outer sleeve has a through groove, and the inner side of the adjusting member is provided with a sliding groove and a retaining groove, with one end of the retaining groove communicating with the sliding groove. The sliding groove extends axially, and the retaining groove extends radially. The disassembly / assembly member also includes a protrusion connected to the moving part. The protrusion passes through the through groove and extends to the sliding groove, so that the disassembly / assembly member connects to the adjusting member. When the adjusting member rotates relative to the outer sleeve, causing the protrusion to slide from the sliding groove to the retaining groove, the axial movement of the adjusting member relative to the outer sleeve can drive the disassembly / assembly member to move, thereby causing the corresponding connecting part to extend out of the disassembly / assembly end.

[0007] In some embodiments, a guide is provided between each pair of adjacent moving parts, the guide extending axially to guide the moving parts to move axially.

[0008] In some embodiments, in each pair of adjacent moving parts, the moving part closer to the disassembly / assembly end can move relative to the guide towards the top, so that when the moving part closer to the top moves towards the disassembly / assembly end, the two adjacent moving parts are relatively close to each other, and the moving part closer to the top is fixedly connected to the guide, so that the moving part closer to the disassembly / assembly end can drive the moving part closer to the top to move towards the disassembly / assembly end.

[0009] In some embodiments, in each pair of adjacent moving parts, the moving part closer to the disassembly end has a functional hole, a first stop surface is provided in the functional hole, a second stop surface is provided at one end of the guide, and the other end of the guide passes through the functional hole and is fixedly connected to the moving part closer to the top. The second stop surface abuts against the first stop surface to limit the relative distance between the two adjacent moving parts.

[0010] In some embodiments, the wrench further includes a first elastic element and a second elastic element, the first elastic element being connected to an adjusting element and a disassembly end, respectively, and the second elastic element being connected to a top end and a moving part closest to the top end, respectively, and the first elastic element and the second elastic element being used to move the adjusting element and the moving part toward the top end.

[0011] In some embodiments, the adjusting member is connected to a second ball and a second positioning member, and the outer wall of the outer sleeve is provided with a plurality of second positioning grooves. The second ball and the second positioning member are connected to the second positioning grooves to position the adjusting member.

[0012] In some embodiments, the connecting part connected to the movable part closest to the top is a polygonal column, while the other connecting parts are cylindrical polygonal columns.

[0013] In some embodiments, the wrench further includes a handle rotatably connected to a top end, the handle having a groove and the top end having a protrusion, the handle being rotated relative to the outer sleeve to engage the groove with the protrusion to position the handle.

[0014] In some embodiments, the handle includes a first rod and a second rod. The first rod is rotatably connected to the top end and has a groove. A connecting rod is provided at one end of the first rod facing the second rod. The second rod is provided with a moving groove. The connecting rod connects to the moving groove, so that the second rod can move relative to the first rod. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0068] It should be noted that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions, are merely illustrative examples and should not constitute any limitation on this application.

[0069] Wrenches are mainly used for removing and installing screws. Currently, to remove and install screws of different sizes, it is necessary to prepare multiple wrenches of different sizes and switch between them to remove and install the appropriate size. However, switching between multiple wrenches can easily lead to the loss of some wrenches.

[0070] This application provides a wrench capable of providing connecting parts of different sizes for assembling and disassembling workpieces of different specifications. The wrench includes an outer sleeve, an adjusting member, and multiple disassembly / assembly parts. The outer sleeve extends axially and has a disassembly / assembly end and a top end, and is provided with multiple first positioning members. The multiple disassembly / assembly parts are disposed on the outer sleeve and are movable relative to the outer sleeve axially. Each disassembly / assembly part includes a connected moving part and a connecting part. The moving part is provided with a first positioning groove for connecting the first positioning member. Each moving part is arranged axially at adjustable intervals from adjacent moving parts. Multiple connecting parts all extend axially to the disassembly / assembly end. From the disassembly / assembly end toward the top end, each connecting part is sequentially fitted onto adjacent connecting parts, and the connecting part is used for assembling and disassembling workpieces. The adjusting member is fitted on the outer sleeve and is movable relative to the outer sleeve, used to drive one disassembly / assembly part to move axially toward the disassembly / assembly end, causing the first positioning member to disengage from the first positioning groove, and the corresponding connecting part to extend out of the disassembly / assembly end.

[0071] In the aforementioned wrench, the adjusting component drives the disassembly / assembly part to move axially, causing the corresponding connecting part to extend from the disassembly / assembly end of the outer sleeve to connect to the workpiece, thereby disassembling and assembling the workpiece. When it is necessary to disassemble and assemble workpieces of different specifications, the adjusting component moves relative to the outer sleeve to connect the disassembly / assembly part adapted to the workpiece size, so that the connecting part at the disassembly / assembly end of the outer sleeve can adapt to the workpiece. When the wrench is applied to disassemble and assemble screws, the connecting part extending from the disassembly / assembly end is inserted into the screw and drives the screw to rotate, thus completing the disassembly and assembly of the screw.

[0072] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0073] Please see Figure 1 An embodiment of this application provides a wrench 100 that can assemble and disassemble various workpieces of different sizes by rotating a workpiece (not shown).

[0074] Please see Figure 2 The wrench 100 includes an outer sleeve 10, an adjusting member 30, and multiple disassembly / assembly parts 20. The outer sleeve 10 extends along the Z-axis. Multiple disassembly / assembly parts 20 are disposed on the outer sleeve 10 and are movable relative to the outer sleeve 10 along the Z-axis. Each disassembly / assembly part 20 includes a connected moving part 21 and a connecting part 22. Each moving part 21 is spaced apart from its adjacent moving part 21 along the Z-axis in an adjustable manner. The connecting parts 22 are all used for disassembling and assembling workpieces. The adjusting member 30 is sleeved on the outer sleeve 10 and is movable relative to the outer sleeve 10. The adjusting member 30 is used to drive the moving part 21 of one disassembly / assembly part 20 to move along the Z-axis.

[0075] The outer sleeve 10 has a disassembly end 11 and a top end 12. Multiple connecting portions 22 extend axially (Z) to the disassembly end 11. From the disassembly end 11 towards the top end 12, the outer periphery of the connecting portions 22 connected to each moving part 21 decreases sequentially. Each connecting portion 22 on each moving part 21 is fitted onto the connecting portion 22 on an adjacent moving part 21 closer to the top end 12, so that each connecting portion 22 is fitted onto the adjacent connecting portion 22 in a stepwise manner. The connecting portions 22 are used for disassembling and assembling workpieces. The outer sleeve 10 is provided with multiple first positioning members 13, which face inwards towards the inner side of the outer sleeve 10. Each moving part 21 is provided with a first positioning groove 2101. The first positioning groove 2101 is used to connect to the first positioning member 13 to position the moving part 21. When the adjusting member 30 drives the moving part 21 to move toward the disassembly end 11, the first positioning member 13 disengages from the first positioning groove 2101, and the corresponding connecting part 22 extends out of the disassembly end 11. The extended connecting part 22 can connect to the workpiece to disassemble and assemble the workpiece.

[0076] In some embodiments, when the wrench 100 is placed vertically, the axial direction Z is parallel to the vertical direction. The disassembly end 11 is the bottom end of the outer sleeve 10. When the wrench 100 is not in use, a plurality of connecting parts 22 are horizontally arranged near one end of the disassembly end 11, and the other ends of the plurality of connecting parts 22 are fixedly connected to the central region of the moving part 21. From the disassembly end 11 toward the top end 12, the length of the connecting part 22 connected to each moving part 21 increases sequentially, and the length of the connecting part 22 is the dimension of the connecting part 22 along the axial direction Z.

[0077] In some embodiments, the workpiece is an internal angle workpiece. Specifically, the workpiece is a screw or bolt.

[0078] In some embodiments, the connecting part 22 is used to connect workpieces. There are multiple connecting parts 22, and each connecting part 22 has a different outer peripheral size, so that multiple connecting parts 22 with different sizes can connect workpieces of different specifications.

[0079] According to the specifications of the workpiece to be disassembled or assembled, a disassembly / assembly part 20 adapted to the workpiece size is selected. The selected disassembly / assembly part 20 is driven to move axially Z by the adjusting part 30, causing the corresponding connecting part 22 to extend from the disassembly / assembly end 11 of the outer sleeve 10 to connect to the workpiece. Once the connecting part 22 connects to the workpiece, the workpiece can be disassembled or assembled. When the wrench 100 is applied to the disassembly / assembly of screws, the connecting part 22 extends from the disassembly / assembly end 11 of the outer sleeve 10, inserts into the screw, and drives the screw to rotate, thus completing the disassembly / assembly of the screw. Similarly, when the wrench 100 is applied to the disassembly / assembly of screws, the connecting part 22 extending from the disassembly / assembly end 11 is inserted into the screw and drives the screw to rotate, thus completing the disassembly / assembly of the screw.

[0080] In some embodiments, the first positioning member 13 is a spring ball plunger. The spring ball plunger can engage with the first positioning groove 2101 within a preset force range to position the moving part 21 and prevent the moving part 21 from moving towards the disassembly end 11 without external force. When the force applied to the moving part 21 by the adjusting member 30 exceeds the preset force range, the spring ball plunger will disengage from the first positioning groove 2101, thereby canceling the positioning of the moving part 21 and allowing the moving part 21 to move relative to the outer sleeve 10 with the adjusting member 30.

[0081] In some embodiments, the wrench 100 further includes a second elastic member 25. The second elastic member 25 is connected to the top end 12 and the moving part 21 closest to the top end 12. The second elastic member 25 is used to move the moving part 21 toward the top end 12. When the adjusting member 30 rotates relative to the outer sleeve 10 to make the protrusion 23 slide from the slot 302 into the slide groove 301, the moving part 21 can elastically reset along the axial Z under the action of the second elastic member 25 until the first positioning member 13 engages with the first positioning groove 2101 to position the distance the moving part 21 moves along the axial Z under the action of the second elastic member 25, preventing the moving part 21 from moving excessively toward the top end 12 under the action of the second elastic member 25.

[0082] Please see Figure 1 and Figure 2 In some embodiments, the outer sleeve 10 has a through groove 101. The through groove 101 extends along the axial direction Z. See also Figure 3 The adjusting member 30 has a sliding groove 301 and a retaining groove 302 on its inner side, with one end of the retaining groove 302 communicating with the sliding groove 301. The sliding groove 301 extends along the axial direction Z. The retaining groove 302 extends along the axial direction X. The axial direction X is perpendicular to the axial direction Z. The disassembly / assembly member 20 also includes a protrusion 23 connected to the moving part 21. Please refer to... Figure 1 The protrusion 23 passes through the through groove 101 and extends to the slide groove 301, so that the disassembly part 20 is connected to the adjustment part 30.

[0083] In one operating state, the slide groove 301 corresponds to the through groove 101 of the outer sleeve 10. The driving adjustment member 30 moves axially Z relative to the outer sleeve 10, so that the protrusion 23 of the disassembly / assembly part 20, which is adapted to the workpiece size, is located at the position where the slide groove 301 and the slot 302 communicate. The driving adjustment member 30 rotates relative to the outer sleeve 10, so that the protrusion 23 slides from the slide groove 301 to the slot 302. At this time, the adjustment member 30 engages a disassembly / assembly part 20. The axial Z movement of the adjustment member 30 relative to the outer sleeve 10 can drive the connected disassembly / assembly part 20 to move. The protrusion 23 moves axially Z within the through groove 101, so that the corresponding connecting part 22 protrudes from the disassembly / assembly end 11.

[0084] Please see Figures 1 to 3 In some embodiments, the outer sleeve 10 is cylindrical, the moving part 21 is disc-shaped, and the adjusting member 30 is annular, so that the adjusting member 30, which is sleeved on the outer periphery of the outer sleeve 10, can move relative to the outer sleeve 10 along the axial direction Z or rotate about the central axis of the outer sleeve 10. The central axis of the outer sleeve 10 is parallel to the axial direction Z.

[0085] The through groove 101 guides the protrusion 23 to move along the axial direction Z, so that the disassembly and assembly parts 20 can only move along the axial direction Z, and prevents the disassembly and assembly parts 20 from rotating relative to the outer sleeve 10. The extended connecting part 22 is connected to the workpiece, and the outer sleeve 10 is driven to rotate, so that multiple disassembly and assembly parts 20 and adjusting parts 30 rotate together with the outer sleeve 10 around the central axis. The connecting part 22 drives the workpiece to rotate to disassemble and assemble the workpiece.

[0086] In some embodiments, the outer sleeve 10 is provided with two through slots 101 spaced apart, each moving part 21 is connected with two protrusions 23 spaced apart, and each through slot 101 is provided with a protrusion 23. The inner side of the adjusting member 30 is provided with two sliding grooves 301 and two locking grooves 302, and one sliding groove 301 corresponds to one through slot 101, so that the adjusting member 30 can more stably drive the connected disassembly and assembly parts 20 to move.

[0087] Please see Figure 2 In some embodiments, a guide 24 is provided between every two adjacent moving parts 21. The guide 24 extends along the axial direction Z to guide the moving parts 21 to move along the axial direction Z, so that the moving parts 21 can only move along the axial direction Z, and to prevent relative rotation between multiple moving parts 21.

[0088] Please see Figure 4 and Figure 5 In some embodiments, two guide members 24 are provided between each pair of adjacent moving parts 21. The two guide members 24 are respectively provided on two pairs of sides of the connecting part 22 to guide the moving parts 21 to move more stably.

[0089] In some embodiments, in each pair of adjacent moving parts 21, the moving part 21 closer to the disassembly / assembly end 11 can move relative to the guide 24 toward the top end 12. Thus, when the moving part 21 closer to the top end 12 moves toward the disassembly / assembly end 11, the moving part 21 closer to the disassembly / assembly end 11 does not move, and the two adjacent moving parts 21 move closer to each other, so that the connecting part 22 connected to the moving part 21 closer to the top end 12 can extend out of the disassembly / assembly end 11.

[0090] In each pair of adjacent moving parts 21, the moving part 21 closer to the top 12 is fixedly connected to the guide member 24. Thus, when the moving part 21 closer to the disassembly end 11 moves toward the disassembly end 11, it can drive the moving part 21 closer to the top 12 to move toward the disassembly end 11 together, so that the connecting part 22 connected to the moving part 21 closer to the disassembly end 11 can protrude from the disassembly end 11, and the connecting part 22 connected to the moving part 21 closer to the top 12 can fill the connecting part 22 protruding from the disassembly end 11, thereby increasing the strength of the connecting part 22 that fits the workpiece.

[0091] Please see Figure 4 and Figure 5In some embodiments, in each pair of adjacent moving parts 21, the moving part 21 closer to the disassembly end 11 has a functional hole 2102, and a first stop surface 2103 is provided in the functional hole 2102. One end of the guide member 24 is provided with a second stop surface 2401. The other end of the guide member 24 passes through the functional hole 2102 and is fixedly connected to the moving part 21 closer to the top end 12. The second stop surface 2401 abuts against the first stop surface 2103 to limit the relative distance between adjacent moving parts 21.

[0092] In the movable part 21 with the functional hole 2102, the second stop surface 2401 abuts against the first stop surface 2103 to restrict the movement of the movable part 21 relative to the guide 24 toward the disassembly end 11, so that the movable part 21 can only move toward the top end 12 relative to the guide 24.

[0093] In some embodiments, the guide 24 is a high-grade screw, which passes through the functional hole 2102 and is threaded to the moving part 21 closer to the top end 12.

[0094] In some embodiments, the connecting portion 22 connected to the moving portion 21 closest to the top 12 is a polygonal column, while the other connecting portions 22 are cylindrical polygonal columns.

[0095] Understandably, the connecting part 22 connected to the moving part 21 closest to the top 12 is solid, while the other connecting parts 22 are hollow. This allows the connecting part 22 on each moving part 21 to fit onto the connecting part 22 on the adjacent moving part 21 closer to the top 12, moving from the disassembly end 11 towards the top 12. When the moving part 21 closest to the top 12 moves towards the disassembly end 11, the connecting part 22 connected to it extends out of the disassembly end 11. The solid connecting part 22 has higher strength and can complete the disassembly and assembly of the workpiece.

[0096] In some embodiments, the cross-section of the connecting portion 22 along the axial X direction is polygonal. Those skilled in the art can set the cross-section of the connecting portion 22 along the axial X direction to hexagonal, pentagonal, or quadrilateral according to actual needs, and no limitation is made here.

[0097] In some embodiments, the wrench 100 has five disassembly parts 20, each of which includes a moving part 21 and a connecting part 22. The five connecting parts 22 have different outer peripheral dimensions, making them suitable for five different workpiece sizes. However, this is not a limitation; the number of disassembly parts 20 can be set according to the type of workpiece and the needs of use.

[0098] Five movable parts 21 are arranged sequentially at a preset distance along the Z-axis, and the length of the connecting part 22 connected to each movable part 21 increases sequentially at a preset distance.

[0099] Please see Figure 4For ease of distinction, viewed from the detachment end 11 towards the top end 12, the five moving parts 21 are respectively defined as the first moving part 211, the second moving part 212, the third moving part 213, the fourth moving part 214, and the fifth moving part 215. Correspondingly, the connecting parts 22 connected to the five moving parts 21 are respectively defined as the first connecting part 221, the second connecting part 222, the third connecting part 223, the fourth connecting part 224, and the fifth connecting part 225.

[0100] In one usage state, the wrench 100 is placed vertically. When the adjusting member 30 drives the fifth moving part 215 to move downward, the fifth connecting part 225 extends out of the disassembly / assembly end 11. The fifth connecting part 225 is a solid connecting part 22 with high strength, and can be inserted into a workpiece for disassembly / assembly. When the adjusting member 30 drives the fourth moving part 214 to move downward, the fourth connecting part 224 and the fifth connecting part 225 extend out of the disassembly / assembly end 11 together. The fourth connecting part 224 is fitted around the outer periphery of the fifth connecting part 225, and the fifth connecting part 225 fills the fourth connecting part 224 to increase the strength of the fourth connecting part 224. At this time, the fourth connecting part 224 can be inserted into a workpiece for disassembly / assembly. Similarly, when the adjusting member 30 drives the first disassembly / assembly member 20 to move downward, the first connecting part 221, the second connecting part 222, the third connecting part 223, the fourth connecting part 224 and the fifth connecting part 225 extend out of the disassembly / assembly end 11 together. The second connecting part 222, the third connecting part 223, the fourth connecting part 224 and the fifth connecting part 225 are sequentially fitted around the outer periphery of the first connecting part 221 to increase the strength of the first connecting part 221. The first connecting part 221 can be inserted into the workpiece to disassemble / assemble the workpiece.

[0101] In some embodiments, when the adjusting member 30 drives the first disassembly member 20 to move downward, the second elastic member 25 provides a pulling force toward the top end 12 to the fifth connecting part 225, the fifth connecting part 225 provides a pulling force toward the top end 12 to the fourth connecting part 224 via the guide member 24, the fourth connecting part 224 provides a pulling force toward the top end 12 to the third connecting part 223 via the guide member 24, the third connecting part 223 provides a pulling force toward the top end 12 to the second connecting part 222 via the guide member 24, and the second connecting part 222 provides a pulling force toward the top end 12 to the first connecting part 221 via the guide member 24, so that the distance between adjacent moving parts 21 remains unchanged.

[0102] Please see Figure 1 and Figure 2In some embodiments, the wrench 100 further includes a first elastic element 15. The first elastic element 15 is connected to the adjusting element 30 and the disassembly end 11. The first elastic element 15 is used to move the adjusting element 30 toward the top end 12. When the adjusting element 30 rotates relative to the outer sleeve 10, causing the protrusion 23 to slide from the slot 302 into the slide groove 301, the adjusting element 30 can elastically reset along the Z-axis under the action of the first elastic element 15.

[0103] Please see Figure 3 The adjusting member 30 is connected to the second positioning member 31. (See also...) Figure 2 The outer wall of the outer sleeve 10 is provided with a plurality of second positioning grooves 102. When the connecting part 22 extends out of the disassembly end 11, the second positioning member 31 connects with the second positioning groove 102 to position the adjusting member 30.

[0104] In some embodiments, the second positioning member 31 is a spring ball plunger. When the adjusting member 30 rotates relative to the outer sleeve 10, causing the protrusion 23 to slide from the slot 302 into the slide groove 301, and the force on the adjusting member 30 exceeds the range of the preset force, the spring ball plunger will disengage from the second positioning groove 102, and the adjusting member 30 can move relative to the outer sleeve 10.

[0105] When the adjusting member 30 rotates relative to the outer sleeve 10, causing the protrusion 23 to slide from the slot 302 into the groove 301, and the adjusting member 30 is not subjected to external force, the adjusting member 30 can elastically reset along the axial Z under the action of the first elastic member 15 until the second positioning member 31 engages with the second positioning groove 102 to position the distance the adjusting member 30 moves along the axial Z under the action of the first elastic member 15, preventing the adjusting member 30 from moving excessively towards the top 12 under the action of the first elastic member 15.

[0106] Please see Figure 1 and Figure 2 In some embodiments, the wrench 100 also includes a handle 40. The handle 40 is rotatably connected to the tip 12. See also Figure 6 The handle 40 has a groove 4101. The top 12 has a protrusion 14. The handle 40 rotates relative to the outer sleeve 10 so that the groove 4101 connects with the protrusion 14 to position the handle 40, making it easy to adjust the angle between the handle 40 and the outer sleeve 10 for convenient use and storage.

[0107] Please see Figure 6 In some embodiments, the handle 40 includes a first rod portion 41 and a second rod portion 42. The first rod portion 41 is rotatably connected to the top end 12, and a groove 4101 is provided in the first rod portion 41. A connecting rod 43 is provided at one end of the first rod portion 41 facing the second rod portion 42, and the connecting rod 43 is used to connect the first rod portion 41 and the second rod portion 42. The second rod portion 42 is provided with a moving groove 4201. The connecting rod 43 connects to the moving groove 4201, so that the second rod portion 42 can move relative to the first rod portion 41.

[0108] Please see Figure 6 In some embodiments, the first rod portion 41 is provided with two grooves 4101. When one of the grooves 4101 is connected to the protrusion 14, the first rod portion 41 is parallel to the axial direction X. Rotating the second rod portion 42 causes the second rod portion 42 to rotate relative to the first rod portion 41 and the connecting rod 43 through the moving groove 4201, thereby folding the handle 40 to prevent the handle 40 from taking up too much space and to facilitate the storage of the wrench 100.

[0109] Please see Figure 7 In some embodiments, when another groove 4101 connects to the protrusion 14, the first rod portion 41 is parallel to the axial direction Z. Rotating the second rod portion 42 and moving it relative to the first rod portion 41 and the connecting rod 43 via the moving groove 4201 causes the second rod portion 42 to be parallel to the axial direction X, or to be non-parallel to the first rod portion 41. At this time, torque can be transmitted through the second rod portion 42 and the first rod portion 41, causing the outer sleeve 10, multiple disassembly / assembly parts 20, and the workpiece connected to the protruding connecting part 22 to rotate together, completing the disassembly / assembly of the workpiece. The second rod portion 42 is convenient for user operation and gripping.

[0110] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of disclosure of this application.
