When disassembly is required, the fixing screw rod 115 is rotated in the opposite direction to make the L-shaped block 117 lose connection with the fixing groove 114, thereby disassembling the vacuum pump body 113, and in the vacuum pump body 113, When the pump body 113 is working, the heat dissipation fan 122 is started through the external controller, and the heat dissipation fan 122 dissipates heat for the vacuum pump body 113. When the vacuum pump body 113 vibrates during operation, the T-shaped mounting slot 100 moves, thereby driving the guide rod 214 to move under the traction of the limit rod 230. The guide rod 214 drives the piston block 212 to move through the piston rod 213, and the piston block 212 then drives the shock-absorbing spring 211 to contract. The shock-absorbing spring 211 then acts on the vacuum pump body 113. While the piston block 212 moves, the air in the cylinder 210 is pushed out and drawn in through the exhaust hole 220, thereby cooperating with the shock-absorbing spring 211 to perform shock absorption, so that the shock-absorbing spring 211 contracts and rebounds at a uniform speed, thereby improving the shock absorption effect.
