[0002] As an important part of the automotive industry, automobile maintenance plays a vital role in the safety and reliability of automobiles. The engine is the most critical part of the car and the most important factor in determining the performance of the car. The valve lock is a component of the engine valve mechanism. It forms a valve group with valves, valve spring seats, valve springs, valve guides and other parts to ensure that the valve can reliably move according to the designed trajectory. Its assembly affects the performance of the valve mechanism and thus affects the engine performance. In the maintenance process of automobile engines, the replacement and maintenance of valve locks is a common operation, and it is also an operation with certain difficulty and danger.

[0003] At present, the loading and unloading of valve lock plates in automobile maintenance requires the use of a bow-shaped valve spring compressor, and then manual installation and removal of the valve lock plates. Traditional manual operations are prone to errors such as falling off, flipping, and improper installation, which leads to low efficiency in valve lock plate installation. Utility Model Content

[0008] Furthermore, in the above device, both ends of the return spring are respectively fixed to the end of the push rod and the bending tube that are close to each other.

[0009] Among them, a guide cylinder is fixed to one end of the bending cylinder close to the push rod in the above device, and the guide cylinder is located between the reset spring and the magnetic rod. An annular telescopic groove is opened at one end of the push rod close to the bending cylinder. Pushing the push rod can make the telescopic groove sleeve on the guide cylinder.

[0010] Furthermore, the interior of the guiding cylinder in the above-mentioned device communicates with the inner column groove, and the inner diameter of the guiding cylinder is the same as the diameter of the inner column groove.
