A handle 407 is installed on the right side of the bidirectional screw 404 at the extended end. In the present embodiment, when in use, the clamping parts in the fixing mechanism 4 are first replaced according to the shape of the mechanical pump. When the clamping parts are replaced, the mechanical pump is placed on the fixing plate 3, and the handle 407 is rotated to drive the bidirectional screw 404 to rotate, so that the two sliders 204 slide close to each other on the bidirectional screw 404 and in the rectangular shell 402, and the two connecting plates 406 move accordingly. The clamping parts in the fixing mechanism 4 clamp the mechanical pump on the fixing plate 3.

The clamping parts in the fixing mechanism 4 clamp the mechanical pump on the fixing plate 3. When the mechanical pump is running, the vibration generated will be absorbed by the shock absorbing mechanism 2 to reduce the vibration, thereby facilitating the installation and fixation of the mechanical pump, with a wide range of applications and strong practicality, thereby reducing the vibration of the mechanical pump. When the two connecting plates 406 move close to each other, the two connecting splints 409 are driven to move accordingly, and the rubber pad is in close contact with the mechanical pump, and the sliding setting between the mounting notch 408 and the connecting splint 409 can facilitate the shape of the connecting splint 409 to be replaced according to the shape of the mechanical pump, thereby improving practicality. By pulling the connecting block 414, The cylinder 411 and the limit block 413 move upward and compress the spring three 412, and then the connecting splint 409 is inserted into the installation notch 408, and the connecting block 414 is released. Under the resetting elastic force of the spring three 412, the cylinder 411, the limit block 413 and the connecting block 414 are driven to reset, and the cylinder 411 is inserted into the circular groove 415 to fix the connecting splint 409, thereby realizing the installation and fixation of the connecting splint 409. By setting the friction pad, the friction resistance in contact with the connecting splint 409 is increased. To improve the stability of fixation, the rectangular shell 402 is stably supported by setting the number and position of the support rods 403. When the mechanical pump is in operation, the vibration generated will press the damping rod 209 and the spring 2 210 downwardly by the fixed plate 3. The two double-ring rods 206 rotate on the shaft column 1 205 and the shaft column 2 207 and produce an angle change, pushing the two sliders 204 to slide in the slide groove 201 and compressing the spring 1 203. With their mutual cooperation, the vibration amplitude is reduced, thereby playing a role in shock absorbing the mechanical pump.
