In this way, when the second top plate and the first top plate are touched and squeezed externally, they can be effectively buffered and compressed by the first hydraulic buffer and the second hydraulic buffer, and can be connected and stressed with each other during compression, so as to avoid damage caused by direct impact.

[0020] 2. The utility model is provided with a third bearing plate. When a person is using the slender swing oil cylinder body and the output shaft of the swing oil cylinder body is in a working state, the third top plate is installed on the third bearing plate by means of the third hydraulic buffer. In this way, the third top plate after installation can block the output shaft of the swing oil cylinder body, so that when there is an accidental external touch, the extrusion force will be applied to the third top plate, effectively avoiding the situation that the output shaft of the swing oil cylinder body is directly touched and squeezed and damaged. In addition, when the third top plate is impacted, the third hydraulic buffer can buffer the impact force, thereby achieving the effect of anti-compression protection.
