[0002] When the twist clamp is in use, it needs to be inspected and maintained regularly. When replacing the bearing of the hinge joint, the front and rear frames must be separated to replace the bearing. The nut is an interference fit and is very difficult to disassemble. At present, when disassembling the nut, a sledgehammer is generally used to hit the chisel to hit the locking nut positioning block for disassembly and assembly, and the locking nut is knocked loose, and then the nut is screwed out along the thread groove. This method is time-consuming and easily causes damage to the locking nut assembly positioning block during the disassembly and assembly process, resulting in the need to replace the locking nut, increasing maintenance costs. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a tool for disassembling and assembling the locking nut of a twisted hinge joint, so as to solve the problem that when disassembling and assembling the nut, a sledgehammer is generally used to hit the locking nut positioning block with a chisel to loosen the locking nut, and then the nut is screwed out along the thread groove. This method is time-consuming and can easily cause damage to the locking nut assembly positioning block during the disassembly and assembly process, resulting in the need to replace the locking nut, increasing maintenance costs.

[0007] As a further improvement of the above technical solution: the chuck is a ring body with a central through-hole, and the inner diameter of the chuck is larger than the inner diameter of the locking nut.

[0008] The beneficial effect of this improvement is that because the end of the bearing protrudes from the locking nut, the inner diameter of the chuck is larger than the inner diameter of the locking nut to accommodate the protruding part of the bearing.

[0009] In order to increase the accommodation space for the bearing protrusion;

[0010] As a further improvement of the above technical solution: a fixing rod is arranged around the slot and the chuck.

[0011] The beneficial effects of this improvement are as follows: the lengths of bearing protrusions are different, and the thickness of the chuck alone cannot meet the requirements for bearings with larger protrusions. A fixing rod is arranged around the slot and the chuck to increase the distance between the slot and the chuck, thereby greatly increasing the accommodating space for the bearing protrusion.

[0015] In order to make the chuck more stably fit on the outside of the locking nut;

[0016] As a further improvement of the above technical solution: magnet sheets are equidistantly arranged around the lower side of the chuck.

[0017] The beneficial effect of this improvement is that magnet sheets are equidistantly arranged around the lower side of the chuck to facilitate the adsorption of the locking nut, so that the chuck can be more stably sleeved on the outside of the locking nut.

[0018] In order to increase the structural strength of the connecting shell;

[0019] As a further improvement of the above technical solution: reinforcing steel plates are provided on both the upper and lower sides of the connecting shell, and the rotating shaft passes through the reinforcing steel plates to the outside.

[0020] The beneficial effect of this improvement is that reinforced steel plates are provided on both the upper and lower sides of the connecting shell. During disassembly, while the hydraulic jack generates a huge thrust, the plug block is subjected to torsional resistance, and part of the thrust will directly act on the connecting shell. The structural strength of the connecting shell is increased by reinforcing the steel plates, thereby increasing the ability to withstand strong thrust.

[0021] In order to increase the stability of the tooth plate movement;

[0022] As a further improvement of the above technical solution: stable grooves are provided on the upper and lower sides of the connecting shell corresponding to the tooth plate, and a sliding block 2 is slidably provided inside the stable groove, and the sliding block 2 is slidably connected to the tooth plate.

[0023] The beneficial effect of this improvement is that the tooth plate can be restricted by sliding the slider 2 inside the stabilizing groove, thereby increasing the stability of the tooth plate movement.

[0024] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The working principle and use process of this utility model:

[0034] When in use, when it is necessary to remove the locking nut 17, align the teeth 15 of the chuck 14 with the positioning blocks around the locking nut 17 and insert them, then pick up the connecting shell 2, insert one side of the plug block 8 into the slot 12 of the connecting disk 11, start the hydraulic jack 3, and the output end of the hydraulic jack 3 pushes the end block 4 to move the tooth plate 6 through the slider, and the tooth plate 6 drives the transmission tooth 7 to rotate, and the transmission tooth 7 drives the plug block 8 to rotate through the rotating shaft, and the upper and lower plug blocks 8 rotate at the same time. When different plug blocks 8 are inserted into the slot 12, the rotation direction is opposite, and the plug block 8 corresponding to the direction of removing the locking nut 17 is inserted into the slot 12. The connecting plate 11 is driven to rotate, and the connecting plate 11 drives the clamping teeth 15 to rotate through the chuck 14, and the clamping teeth 15 drive the locking nut 17 to twist through the positioning block. The huge hydraulic thrust of the hydraulic jack 3 can be transformed into a strong torsional force through the tooth plate 6 acting on the transmission tooth 7, thereby breaking through the interference fit friction between the locking nut 17 and the bearing, and loosening the locking nut 17. There is no need to use a sledgehammer to hit the locking nut positioning block for disassembly and assembly, thereby avoiding the positioning block from being damaged by impact, keeping the locking nut 17 intact, facilitating reuse, avoiding increasing maintenance costs, and being able to quickly disassemble the locking nut 17, increasing Maintenance efficiency. In addition, when in use, because the end of the bearing will protrude from the locking nut 17, the inner diameter of the chuck 14 is larger than the inner diameter of the locking nut 17 to accommodate the protruding part of the bearing. In addition, the protruding lengths of the bearings are different, and the thickness of the chuck 14 alone cannot meet the needs of bearings with more protrusions. A fixing rod 13 is arranged around the slot 12 and the chuck 14. The distance between the slot 12 and the chuck 14 is increased by the fixing rod 13, thereby greatly increasing the accommodating space for the protrusion of the bearing. In addition, the short rod passes through the chuck 14 to the upper side thread to set the nut, which is convenient for disassembly of the clamping tooth 15. In addition, magnet sheets 16 are equidistantly arranged around the lower side of the chuck 14 to facilitate the adsorption of the locking nut 17, so that the chuck 14 can be more stably sleeved on the outside of the locking nut 17, and reinforcing steel plates 10 are arranged on the upper and lower sides of the connecting shell 2. During disassembly, the hydraulic jack 3 generates a huge thrust while the plug 8 is subjected to torsional resistance. Part of the thrust will directly act on the connecting shell 2. The structural strength of the connecting shell 2 is increased by reinforcing the steel plate 10, thereby increasing the ability to withstand strong thrust. In addition, by sliding the slider 2 on the inner side of the stabilizing groove 9, the tooth plate 6 can be limited to increase the stability of the movement of the tooth plate 6.
