[0029] Specifically, the outlet 102 is connected to the interior of the oil storage tank 109, the circular hole 104 is located on the top center surface of the second mounting block 103, and its inner bottom end extends to the top inner wall of the oil storage tank 109, the inner wall of the oil filling hole 106 is provided with an internal thread, and the outer top surface of the oil filling screw plug 107 is provided with an external thread, wherein the external thread is threadedly connected with the internal thread in a sealing manner, and the outer surface of the rotating block 108 is provided with a plurality of anti-skid grooves, the inner central axis of the oil filling screw plug 107 coincides with the inner central axis of the circular hole 104, and its bottom end extends to the interior of the oil storage tank 109;

[0030] In this embodiment, the rotating block 108 is mainly used to drive the oil filling screw plug 107 to rotate. Under the threaded cooperation between the oil filling screw plug 107 and the oil filling hole 106, the vertical movement of the oil filling screw plug 107 is achieved, which is convenient for subsequent staff to perform oil filling operations.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 A sealing mechanism 2 is provided between the oil filling valve cover 105 and the second mounting block 103, and the sealing mechanism 2 includes an annular groove 201, a threaded hole 202, a sealing ring 203, an annular block 204 and a plum screw 205.
