Referring to fig. 1 to 2, in an embodiment of the present utility model;

example 1: the self-adjusting hydraulic power unit comprises a mounting seat 1, a shell 2 and a hydraulic power unit main body 3, wherein the mounting seat 1 is of a box type structure with one side open, the shell 2 is of a closed box type structure, the shell 2 is embedded and arranged on the inner side of an opening of the mounting seat 1, and the hydraulic power unit main body 3 is assembled at the inner bottom end of the shell 2;

the inner side of the hydraulic power unit main body 3 is attached with a rubber pad 301, the rubber pad 301 is provided with a vertical part and a horizontal part, the size of the vertical part of the rubber pad 301 is larger than that of the end face of the shell 2, the horizontal part of the rubber pad 301 is in a hollowed-out arrangement, and the lower side face of the hydraulic power unit main body 3 is in a hollowed-out arrangement;

through holes are formed between the rubber pad 301 and the mounting seat 1, and the through holes are overlapped, so that air can be directly contacted with the shell 2, and heat on the shell 2 can be quickly dissipated to the outside, and the normal use of the hydraulic power unit main body 3 is ensured.

Example 2: as can be seen by referring to fig. 2 to 4 of the specification, embodiment 2 differs from embodiment 1 in that:

the fixed subassembly is installed at the top of mount pad 1, and fixed subassembly includes: the device comprises a limiting frame 4, a spring 401 and a positioning column 402, wherein the limiting frame 4 is anchored on the upper end face of a mounting seat 1 through bolts, the spring 401 is fixedly connected to the inner top end of the limiting frame 4, the positioning column 402 is fixedly connected to the bottom of the spring 401, and the positioning column 402 penetrates through the mounting seat 1;
