At this time, the connecting plate 4 will drive the mounting rod 15 to move synchronously, and the mounting rod 15 will drive the contact plate 16 to move synchronously. During the movement of the contact plate 16, the return spring 17 will be squeezed. At this time, the fixing rod 5 is inserted into the inside of the fixing block 2, and then the connecting plate 4 is released. At this time, the return spring 17 is reset, driving the contact plate 16 and the mounting rod 15 to move synchronously. When the mounting rod 15 is inserted into the guide groove inside the fixing rod 5, the fixing rod 5 can be fixedly installed with the fixing block 2. At this time, the fixing rod 5 can be fixedly installed with the fixed base 1.

[0038] Taking into account the need to fix and install the top rod 8 when the pin shaft is disassembled and assembled, the fixing assembly includes mounting blocks 12 respectively arranged on the outside of the fixing rod 5, the connecting shaft 6 and the extension rod 7.

The interiors of the multiple positioning frames 23 are provided with guide grooves for the movement of the positioning plates 11. The interiors of the multiple positioning plates 11 are provided with guide grooves for the movement of the L-shaped plug plates 22. When it is necessary to disassemble the pin shaft of a smaller mechanical equipment, you only need to pull the pull ring first. At this time, the pull ring The ring will drive the connecting rod 21 to move synchronously, and the connecting rod 21 will drive the contact plate 19 to move synchronously on the outside of the sliding rod 18. During the movement of the contact plate 19, the contact spring 20 will be squeezed, and the contact plate 19 will also drive the L-shaped plug plate 22 to move synchronously. At this time, the top rod 8 is directly inserted into the inside of the fixed rod 5, and the top rod 8 will drive the positioning plate 11 to move synchronously.

At this time, the top rod 8 and the fixing rod 5 can be fixed and installed, so that the pin shaft of the smaller mechanical equipment can be disassembled by cooperating with the top rod 8 through the power of the forklift. When the pin shaft of the larger mechanical equipment needs to be disassembled, it is only necessary to fix the fixing rod 5, the connecting shaft 6, the extension rod 7 and the top rod 8 in turn through the fixing components (the internal structures of multiple fixing components are the same), without the need for staff to manually use tools such as sledgehammers, which effectively improves the disassembly and assembly efficiency of the pin shaft and reduces the workload of the staff.

[0040] In order to further improve the fixing effect between the fixed base 1 and the fork of the forklift, the upper surfaces of the two fixing straps 10 are bonded with wear-resistant and anti-slip pads 25. Through the provision of the wear-resistant and anti-slip pads 25, the friction between the fixing straps 10 and the forklift forks can be effectively increased, thereby further improving the fixing effect of the fixing straps 10, and further improving the stability of the device during use. In addition, the wear-resistant and anti-slip pads 25 can also effectively play a wear-resistant role on the fixing straps 10, thereby effectively extending the service life of the fixing straps 10.

[0041] In addition, in order to effectively extend the service life of the fixed base 1, a rubber protective pad 14 is bonded to the inner wall of the fixed base 1. During the operation of the forklift, a large impact force will be generated. At this time, the impact force may cause damage to the fixed base 1. Through the setting of the rubber protective pad 14, the impact force can be effectively buffered, thereby effectively protecting the fixed base 1 and effectively extending the service life of the fixed base 1.
