The present invention provides the following embodiments.

[0036] Example 1

[0037] like Figure 1 , Figure 2 As shown, it is a structural schematic diagram of the disassembly and assembly tool in this embodiment. The disassembly and assembly tool in this embodiment includes a connecting handle 100, one end of the connecting handle 100 is detachably equipped with an operating head 200, and the other end of the connecting handle 100 is equipped with a holding handle 300. In this embodiment, the holding handle 300, the connecting handle 100 and the operating head 200 together constitute a disassembly and assembly tool for removing the bolts in the holes of the printing machine.

[0038] In this embodiment, Figure 1As shown, the connecting handle 100 includes a connecting portion 101 and an adjusting portion 102. The connecting portion 101 and the adjusting portion 102 are cylindrical structures with open ends. The operating head 200 is detachably connected to the connecting portion 101 of the connecting handle 100. In this embodiment, the operating head 200 includes an operating head 201 and a fixed handle 202 integrally connected to the operating head 201. Figure 4 As shown, a plurality of telescopic buttons 202a are distributed on the fixing handle 202, and a plurality of fixing holes 101a are distributed on the connecting portion 101. The operating head 200 can be assembled on the connecting handle 100 by the mutual cooperation between the telescopic buttons 202a and the fixing holes 101a.

[0039] In order to further improve the assembly stability of the operating head 200 and the connecting handle 100, the fixed handle 202 is a hexagonal structure. The assembly of the hexagonal fixed handle 202 and the connecting portion 101 ensures the assembly stability of the operating head 200 and the connecting handle 100.

[0040] In addition, if Figure 3 As shown, the holding handle 300 in this embodiment includes a plug-in rod 301 and a holding rod 302. The holding handle 300 is assembled on the adjustment portion 102 of the connecting handle 100, and the holding handle 300 is connected to the connecting handle 100 through the plug-in rod 301. In order to ensure the stable assembly effect of the holding handle 300 and the connecting handle 100, the plug-in rod 301 is a hexagonal structure. The assembly of the hexagonal plug-in rod 301 and the connecting handle 100 ensures the stable effect between the connecting handle 100 and the holding handle 300.

[0041] In addition, in the present embodiment, the adjusting portion 102 of the connecting handle 100 is provided with a telescopic spring 104, and the plug-in rod 301 is inserted into the adjusting portion 102 and abuts against the end of the telescopic spring 104; in the present embodiment, an open groove 102a is provided on the surface of the adjusting portion 102, and a fixing column 301a is fixedly connected to the surface of the plug-in rod 301. When the plug-in rod 301 is inserted into the adjusting portion 102, the fixing column 301a is located in the open groove 102a. When the plug-in rod 301 moves along the length direction of the adjusting portion 102, the fixing column 301a slides in the open groove 102a. When the disassembly and assembly tool in the present embodiment is in use, the operating head 200 is extended into the hole of the printing press to limit the bolt to realize disassembly and assembly. When the depth of the hole is deeper, the plug-in rod 301 in the holding handle 300 moves along the length direction of the adjusting portion 102 to adapt to holes of different depths, thereby ensuring the use effect.

[0042] In this embodiment, in order to ensure the assembly stability between the plug rod 301 and the adjustment part 102, as shown in FIG. Figure 3As shown, a thread is provided on the surface of the adjusting portion 102, and an adjusting sleeve 103 is sleeved on the surface of the adjusting portion 102. The adjusting sleeve 103 is threadedly assembled with the adjusting portion 102, and the adjusting sleeve 103 can be rotated to move along the length direction of the adjusting portion 102. In this embodiment, after the plug-in rod 301 and the adjusting portion 102 are assembled, the adjusting sleeve 103 is rotated to move along the length direction of the adjusting portion 102 until it is pressed against the fixed column 301a, and the adjusting sleeve 103 moves through the fixed column 301a to drive the plug-in rod 301 to move so that the telescopic spring 104 is compressed. The telescopic spring 104 and the adjusting sleeve 103 cooperate with each other to make the plug-in rod 301 and the adjusting portion 102 relatively fixed, thereby ensuring the stability of the connecting handle 100 and the holding handle 300.

[0043] like Figure 5 As shown, in order to further ensure the stability of the holding handle 300 and the connecting handle 100, two adjusting sleeves 103 are provided in this embodiment, and the adjusting sleeves 103 are sleeved on the adjusting part 102 and threadedly assembled with the adjusting part 102. In this embodiment, the adjusting sleeve 103 can be rotated to move along the length direction of the adjusting part 102, and the two adjusting sleeves 103 cooperate with each other to clamp and fix the fixing column 301a, thereby further ensuring the stability of the holding handle 300 and the connecting handle 100.

[0044] In addition, if Figure 5 As shown, in this embodiment, a fixing groove 103a is provided at the end of the adjusting sleeve 103 near the fixing column 301a. When the adjusting sleeve 103 moves along the length direction of the adjusting part 102 and presses against the fixing column 301a, the fixing column 301a is located in the fixing groove 103a at the end of the adjusting sleeve 103, further ensuring the stability between the plug-in rod 301 and the adjusting part 102. It is worth noting that in this embodiment, when the number of the adjusting sleeve 103 is one, the mutual cooperation between the fixing groove 103a on the adjusting sleeve 103 and the fixing column 301a ensures the stability of the holding handle 300 and the connecting handle 100 through the elastic force of the telescopic spring 104. When the number of the adjusting sleeve 103 is two, the relatively arranged adjusting sleeves 103 move so that the fixing groove 103a is aligned to form a limiting hole for limiting the fixing column 301a, thereby ensuring the stability of the holding handle 300 and the connecting handle 100.

[0045] It is worth noting that in this embodiment, the adjustment sleeve 103 is used to limit the fixing column 301a so as to ensure the stability between the holding handle 300 and the connecting handle 100.

[0046] When the disassembly and assembly tool in this embodiment is in operation, the operating head 200 is assembled on the connecting handle 100 through the mutual cooperation between the connecting part 101 and the fixing handle 202, and the operating head 200 limits the bolts in the hole of the printing machine. The connecting handle 100 and the operating head 200 are driven to rotate by the rotation of the holding rod 302 on the holding handle 300 to rotate, so as to disassemble the bolts. When the depth of the hole is deeper, the adjusting sleeve 103 is rotated to move along the length direction of the adjusting part 102, so that the plug-in rod 301 can move along the length direction of the adjusting part 102, and the adjusting sleeve 103 is cooperated with the fixing column 301a to make the plug-in rod 301 and the adjusting part 102 relatively fixed, so that the holding handle 300 and the connecting handle 100 are relatively fixed to achieve the purpose of disassembly and assembly.

The amplifying handle 400 includes a curved transition portion 401 and a fixing portion 402 fixedly connected to the end of the transition portion 401. In this embodiment, the transition portion 401 is detachably connected to the grip rod 302 in the holding handle 300, so that a certain angle is formed between the amplifying handle 400 and the holding handle 300. The operator drives the connecting handle 100 and the operating head 200 to rotate through the fixing portion 402 to achieve the purpose of saving effort.

[0049] In this embodiment, a mounting groove 401a is provided on the transition portion 401. In addition, a fixing ear 302a is fixedly connected to the grip rod 302 in the holding handle 300. When the transition portion 401 is plugged into the grip rod 302, the fixing ear 302a is plugged into the mounting groove 401a, so that the amplifying handle 400 and the holding handle 300 are detachably connected. In this embodiment, a certain angle is formed between the amplifying handle 400 and the holding handle 300. When the operating head 200 is driven to rotate by the amplifying handle 400, a certain labor-saving effect is achieved, thereby ensuring the efficient use of the disassembly and assembly tools.
