[0020] Operating principle: When using the press device to repair vehicle suspensions, the four fastening arms 2 of the spring press component are placed around the spring and their positions are adjusted so that they can firmly fix the spring.
[0021] The two safety locks 21 are hooked onto the spring, and the limit pieces 25 are advanced to lock the safety locks 21. This ensures that the spring is not ejected under tension during the repair process. The power-saving device is installed above the press component, with its gear assembly 37 connected to the drive spindle 22. This ensures that when the handle of the power-saving device is turned, the drive spindle 22 is driven to rotate. The support legs 13 of the protective frame are attached to the base of the repair tool. The hinged first protective frame 4 and the second protective frame 41 are then mounted and connected to the press component using nuts. Finally, the entire tool installation is checked to ensure that all components are reliably connected and can function properly.
