[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] Please refer to the following Figures 1 to 7 A nut disassembling tool according to an embodiment of the utility model is described.

[0028] like Figures 1 to 7 As shown, the nut disassembly and assembly tool according to the embodiment of the utility model includes: a drive assembly 1, a locking assembly 2 and a sleeve 3. The drive assembly 1 includes a drive shell 11, a drive body and a handle 12. The drive body is arranged in the drive shell 11. The drive body (not shown) has an output shaft (not shown) that can drive it to rotate. The handle 12 is two and is arranged on the drive shell 11 at intervals. The locking assembly 2 is connected to the output shaft. The locking assembly 2 has a locking cavity 24, and the inner diameter of the locking cavity 24 is adjustable. One end of the sleeve 3 has a nut hole 31, and the other end of the sleeve 3 is detachably inserted into the locking cavity 24.

[0029] According to the nut disassembly and assembly tool of the embodiment of the utility model, when the nut disassembly and assembly tool is working, the driving body can drive the output shaft to rotate, so as to drive the sleeve 3 to rotate through the locking assembly 2, and then remove or install the nut. Since two handles 12 are provided on the outside of the drive shell 11, it is convenient for the operator to hold it with both hands to adapt to the scene where the nut is difficult to disassemble and assemble. Since the locking assembly 2 has a locking cavity 24, and the inner diameter of the locking cavity 24 is adjustable, the locking assembly 2 can clamp sleeves 3 of different models to expand the application range of the nut disassembly and assembly tool. Therefore, the nut disassembly and assembly tool of the utility model can quickly disassemble and assemble nuts of different models, saving time and effort, and is conducive to improving maintenance efficiency.

[0030] It is understandable that the driving body can be a motor, and the motor drives the output shaft to rotate, so as to drive the locking assembly 2 and the sleeve 3 to rotate. Alternatively, the driving body is an air pump, and the air pump drives the output shaft to rotate, so as to drive the locking assembly 2 and the sleeve 3 to rotate. The present application does not limit the specific driving form of the driving body.

[0031] Among them, the two handles 12 are respectively a first handle 121 and a second handle 122. The first handle 121 can be set at the end of the drive shell 11, and the second handle 122 is set on the side wall of the drive shell 11, so that the operator can hold it more conveniently and the nut disassembly tool can be more stable when working.

[0032] In some embodiments, the locking assembly 2 includes a base 21, a transmission component 22 and a plurality of locking blocks 23. The base 21 is connected to the output shaft. The plurality of locking blocks 23 are arranged at intervals along the circumference of the base 21, and a locking cavity 24 is defined on one side of the axis of the base 21 adjacent to the plurality of locking blocks 23. The transmission component 22 is disposed in the base 21 and connected to the plurality of locking blocks 23. The transmission component 22 can drive the locking blocks 23 to move radially along the base 21 to clamp and release the sleeve 3.

[0033] It is understandable that when the required sleeve 3 is larger, the transmission component 22 can be used to drive the multiple locking blocks 23 away from each other to expand the inner diameter of the locking cavity 24. When the required sleeve 3 is smaller, the transmission component 22 can be used to drive the multiple locking blocks 23 closer to each other to reduce the inner diameter of the locking cavity 24.

[0034] Optionally, the base 21 includes an inner cylinder 211 and an outer cylinder 212, the inner cylinder 211 is sleeved in the outer cylinder 212 and defines an annular accommodating chamber 213 with the outer cylinder 212, the transmission component 22 includes a rotating disk 221 and a bevel gear shaft 222, the rotating disk 221 and the bevel gear shaft 222 are both installed in the accommodating chamber 213, the rotating axis of the rotating disk 221 is consistent with the axis of the inner cylinder 211, and the two ends of the bevel gear shaft 222 are rotatably connected to the inner cylinder 211 and the outer cylinder 212 respectively, and the rotating disk 221 A bevel tooth surface is provided along one side of its axial direction, and the bevel gear shaft 222 is meshed with the bevel tooth surface. An Archimedes spiral tooth 2212 is provided on the other side of the rotating disk 221 along its axial direction. The locking block 23 slides with the base 21 along the radial direction of the base 21. A matching groove 232 is provided on the locking block 23, and the Archimedes spiral tooth 2212 matches with the matching groove 232. When the bevel gear shaft 222 rotates, the bevel gear shaft 222 can drive the rotating disk 221 to rotate, so as to push the locking block 23 to slide along the radial direction of the base 21.

[0035] It can be understood that the rotating disk 221 is sleeved between the outer cylinder 212 and the inner cylinder 211, and the accommodating chamber 213 can radially limit the rotating disk 221 to improve the accuracy of the rotation of the rotating disk 221. Since the bevel gear shaft 222 is meshed with the bevel gear surface, when the bevel gear rotates, it can drive the rotating disk 221 to rotate around the axial direction of the inner cylinder 211. Since the rotating disk 221 is provided with Archimedean spiral teeth 2212 (equidistant spiral teeth) on the other side of the axial direction, the rotating disk 221 can drive the locking block 23 to slide relative to the base 21 along the radial direction of the base 21. The nut disassembly tool of the embodiment of the utility model can improve the stability of the clamping of the sleeve 3 by setting the locking assembly 2 as the above structure, and the structural design is simple, the sleeve 3 is not easy to loosen, and the safety during use is high.

[0036] Optionally, there are multiple bevel gear shafts 222, which are arranged at intervals along the circumference of the base 21, and a rotating port 2221 is provided at one end of the bevel gear shaft 222 away from the inner cylinder 211, and the nut disassembly tool also includes a wrench 4, which can be matched with the rotating port 2221 to rotate in a non-rotatable manner to screw the bevel gear shaft 222. For example, the cross section of the rotating port 2221 is square, and the plug-in portion of the wrench 4 is also square, so that the bevel gear shaft 222 can be driven to rotate by the wrench 4. In addition, since there are multiple bevel gear shafts 222, the stability of the rotating disk 221 when it is subjected to force can be improved, and the problem of jamming when the rotating disk 221 rotates can be reduced.

[0037] In one example, three slide grooves 214 are arranged at intervals along the circumference of the base 21, and the slide grooves 214 extend along the radial direction of the base 21, and the angle between two adjacent slide grooves 214 is 120 degrees. There are three locking blocks 23, and the three locking blocks 23 correspond to the slide grooves 214 one by one. Each locking block 23 is provided with a slide rail 231, and the slide rail 231 is slidably matched with the slide groove 214. The inventor of the present application found through experimental research that when the number of locking blocks 23 is three, the stability of the sleeve 3 when clamped can be ensured, and the production cost of the locking assembly 2 can be reduced.

[0038] Optionally, the locking assembly 2 further includes a connecting flange 25, one side of the connecting flange 25 is detachably connected to the base 21, and the other end of the connecting flange 25 is detachably connected to the output shaft. For example, one side of the connecting flange 25 is detachably connected to the base 21 by bolts, and the other side of the connecting flange 25 is detachably connected to the output shaft by bolts, thereby facilitating the disassembly and replacement of the locking assembly 2, and the disassembly and assembly method is simple, and the processing and manufacturing are convenient.

[0039] Optionally, the locking block 23 has a protrusion 233, and the protrusion 233 protrudes in a direction away from the output shaft. It can be understood that the locking assembly 2 can not only clamp the sleeve 3 through the locking cavity 24, but also extend the protrusion 233 into the sleeve 3 and move the multiple locking blocks 23 away from each other to tighten the sleeve 3, thereby achieving the purpose of locking the sleeve 3, thereby expanding the application range of the locking assembly 2.

[0040] In some embodiments, the nut disassembly and assembly tool further includes a magnetic member (not shown), which is installed in the nut hole 31. For example, the magnetic member is a sheet-like structure, and the magnetic member can be bonded in the nut hole 31, thereby being able to adsorb the nut that is removed or to be installed, so as to facilitate the operator to disassemble and assemble the nut.
