[0035] In the process of measuring the valve lift of the engine, the valve lift needs to be measured accurately. Whether this project meets the specification range is directly related to the performance of the engine test. In the process of measuring the valve lift, the hydraulic tappet and rocker arm need to be disassembled.

[0036] In the related art, when disassembling the hydraulic tappets and rocker arms of the engine, the method generally adopted is to first disassemble many parts such as the cylinder head cover and the camshaft, which is time-consuming and labor-intensive, and the efficiency of parts disassembly and recovery is low.

As the automotive industry develops towards automation and intelligence, higher requirements are placed on the accuracy, efficiency and stability of disassembly tools.
