[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors. Internal combustion engines, for example, typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine including the power unit. For a long time, repair technicians have used screw pullers to remove engine pulley shock absorbers. When there are quality problems or assembly issues with engine peripheral components, removing the engine pulley shock absorber to replace gear chambers, shims, camshafts, gears, crankshafts, etc., is a headache for repair technicians (especially for six-cylinder engines). This is because the screw pullers currently used are very inefficient and labor-intensive; removing the pulley of a six-cylinder engine takes at least twenty minutes, significantly consuming the technician's physical strength and time. Summary of the Invention

[0003] To address the shortcomings of the aforementioned technologies, this application provides a pulley shock absorber disassembly device. Its essence lies in improving upon the fact that traditionally, repair workers have used spiral pullers to disassemble engine pulley shock absorbers. When there are quality issues or assembly problems with engine peripheral components, disassembling the pulley shock absorber is a headache for repair workers (especially for six-cylinder engines) because the currently used spiral pullers are inefficient and labor-intensive, taking at least twenty minutes to disassemble the pulley of a six-cylinder engine.

[0026] Assembly component 200 is set on power supply component 100. According to the model of pulley or shock absorber, the corresponding model of connecting plate 211 is selected. Then, the internal threaded ring 220 on the connecting plate 211 is threaded onto the external threaded ring 120. The repairman holds the handle 113 and pushes the piston end of the jack 111 against the engine. Then, the screw 213 is passed through the square hole 212 and the end of the screw 213 is threaded into the threaded hole on the pulley or shock absorber. The repairman operates the operating lever 112 with his other hand to extend the piston of the jack 111. Under the combined action of the piston of the jack 111 and the screw 213, the pulley or shock absorber is pulled out of the engine. This pulley and shock absorber disassembly equipment is easy to operate and the pulley or shock absorber can be easily pulled out, which reduces the labor intensity of the repairman and improves work efficiency, bringing a better user experience.

[0027] Please see Figure 1 and Figure 2The power supply assembly 100 includes a pull-out part 110 and an external threaded ring 120. The pull-out part 110 includes a jack 111 and an operating rod 112. The operating rod 112 is fixed to the jack 111, and the external threaded ring 120 is fixed to the jack 111. The piston of the jack 111 passes through the external threaded ring 120. The operating rod 112 facilitates the extension and retraction of the piston rod of the jack 111. The pull-out part 110 also includes a handle 113, which is fixed to the outer wall of the jack 111. The holding part 113 is designed to facilitate lifting the jack 111. In this embodiment, the holding part 113 is a handle. The pulling part 110 also includes an anti-slip sleeve 114, which is fitted onto the operating rod 112.
