Abstract
This utility model discloses a lever-type bolt removal tool, relating to the field of vehicle maintenance technology. It includes: a support platform with movable rollers at its bottom; a balance lever with a hook for attaching a pneumatic wrench at one end and a counterweight at the other end; and a support rod with one end vertically mounted on the upper surface of the support platform and the other end hinged to the balance lever. The distance from the support rod to the hook end of the balance lever is less than the distance from the support rod to the counterweight end of the balance lever. This lever-type bolt removal tool can be moved to the wheel bolt to be removed via the rollers. The height of the pneumatic wrench at the other end of the balance lever can be adjusted by changing the weight of the counterweight, thus adapting the height of the pneumatic wrench to the height of the wheel bolt. Therefore, only one person is needed to remove the wheel bolt, significantly improving the efficiency of the removal and assembly work. Simultaneously, the operator does not need to climb to a height, greatly improving the safety of the removal and assembly work.
