[0032] The working principle and use process of the utility model are as follows: when the spring 10 needs to be disassembled during use, the bolt 132 on the mounting plate 131 is rotated so that the bolt 132 can be separated from the mounting seat 12 and the mounting plate 131 after rotation, so that the disassembly block 11 can be disassembled from the mounting seat 12, and then the limiting frame 74 is pulled so that the limiting frame 74 can be moved outwardly and separated from the limiting groove 75 on the assembling block 9, and then the assembling block 9 is moved to the right side so that the assembling block 9 can drive the positioning block 82 to separate from the positioning groove 81, so that the assembling block 9 is disassembled from the fixing plate 6, and the disassembly of the spring 10 is completed. When installing the spring 10, the disassembly block 11 is installed on the mounting seat 12 through the bolts 132 on the mounting plate 131, and then the positioning block 82 on the assembling block 9 is aligned with the positioning groove 81 on the fixing plate 6. At the same time, the tension spring 72 inside the mounting groove 71 will drive the connecting rod 73 to move inward through the tension force, so that after the connecting rod 73 moves inward, it can drive the limiting frame 74 to move inward, so that after the limiting frame 74 moves inward, it can be inserted into the limiting groove 75 on the assembling block 9, thereby limiting the assembling block 9 on the right side of the fixing plate 6, completing the installation of the spring 10, and achieving the effect of auxiliary replacement.

However, the spring is a consumable item and is in high-frequency operation, which will quickly shorten the service life of the spring. The fixed connection of the spring in the device does not facilitate the replacement of the spring, so there are certain limitations.
