After that, the magnet in the slide groove will adsorb the magnetic block, so that the magnetic block extends into the slide groove under the action of the spring potential energy and the magnetic attraction of the magnet, thereby clamping the connecting rod in the placement cavity. After that, the wrench device can be put on the bolt and the handle can be turned to install and remove the bolt.

[0028] 2. By designing push rods, slide plates, tension springs, etc., when encountering bolts of different types, the operator only needs to press the push rod to make the push rod slide toward the middle of the slide groove, so that the push rod will drive the slide plate to move toward the middle of the slide groove, and then the slide plate will push the magnetic block into the movable cavity. After that, the operator holds the wrench device to pull the connecting rod out of the placement cavity. Then the operator selects different wrench devices according to different types of bolts, and pushes the connecting rod on the selected wrench device into the placement cavity to complete the replacement of the wrench device, which is more time-saving and convenient.

[0029] 3. By designing a wrench device, the wrench device can be designed according to different types of bolts, including hexagonal wrenches, hexagonal wrenches and special-shaped wrenches, etc. By designing different types of wrench devices, the application occasions of the disassembly tool are expanded and the practicality of the disassembly tool is improved.
