[0036] refer to Figure 3 , Figure 4 and Figure 5 The fixed block 1602 is fixedly connected to the push block 1601 on the side closest to the push block 1601. The side of the fixed block 1602 away from the push block 1601 passes through the concave groove 10 and extends into the inner cavity of the fixed groove 13, contacting the inner wall of the fixed groove 13.

[0040] The working principle of this utility model:

[0041] When the air compressor needs to be moved, first pull the lever 1704, which moves the transmission rack 1703 upward. During this upward movement, the transmission rack 1703 drives the transmission gear 1701 to rotate. The transmission gear 1701 then drives the push column 1606 to move within the extrusion groove 1702. The push column 1606 then moves the push block 1601, the fixing block 1602, the support column 1603, and the limit block 1605 synchronously, compressing the spring 1604. Once the fixing block 1602 disengages from the fixing groove 13, the adjusting lever 12 can be pressed down to make the moving wheel 15 contact the ground. Then, release the lever 1704. 704, the force released after the spring 1604 is squeezed will push the push block 1601, the fixed block 1602, the support column 1603 and the limit block 1605 to move in opposite directions synchronously. The push block 1601 will drive the push column 1606 to move in opposite directions in the inner cavity of the extrusion groove 1702, and drive the transmission gear 1701 to rotate in opposite directions. The transmission gear 1701 will drive the transmission rack 1703 and the pull rod 1704 to move downwards and reset synchronously, fixing the adjusting rod 12. Then, the positions of the remaining adjusting rods 12 are adjusted in sequence so that the moving wheel 15 contacts the ground. After the adjustment is completed, push the push rod 7 to move the position of the air compressor.

[0042] When the air compressor is in use, the main body 1 of the device vibrates. The vibration force is transmitted through the mounting plate 3 to the spring shock absorbers 6 on both sides of the top of the support frame 4. The spring shock absorbers 6 will reduce the vibration force generated by the main body 1 of the device and reduce the vibration of the main body 1 of the device.

[0043] In summary, this mobile oil-free air compressor, through the coordinated use of a support frame 4, limiting column 5, spring shock absorber 6, push rod, support block 8, concave groove 10, rectangular through hole 11, adjusting rod 12, fixing groove 13, positioning block 14, moving wheel 15, fixing device 16, and control device 17, solves the problem that most existing mobile oil-free air compressors lack the function of shock absorption for the main body of the device on top of the air tank, resulting in large stress on the air tank and the possibility of movement during use, affecting the stability of the equipment.
