[0047] like Figure 8 As shown, the adjusting member 7 includes a heat dissipation strip 71, a connecting plate 72, a through groove 73, and a connecting block 74. The connecting plate 72 is provided with two pieces and is respectively connected to the two sides of the heat dissipation strip 71. A hexagonal hole is provided on the connecting plate 72. The connecting block 74 is provided at one end of the connecting plate 72 away from the heat dissipation strip 71. A through groove 73 is provided in the middle of the connecting block 74.

[0053] Working principle:

[0054] The staff fixes the first end cover 3 and the second end cover 5 to the two ends of the body 4 with hexagonal nuts, aligns the annular portion 61 with the shaft hole 33, and puts the positioning piece 6 into the notch 32. At this time, the hexagonal thread on the first end cover 3 falls into the hexagonal hole in the positioning piece 6 and contacts the anti-slip pad.

[0055] Put the adjusting member 7 on the positioning member 6, align the side of the connecting plate 72 with the hexagonal hole with the second end cover 5, and the extension strip 62 passes through the through groove 73 on the connecting block 74.

At this time, the positioning member 6 and the adjusting member 7 are respectively close to the first end cover 3 and the second end cover 5.

[0056] Put the collar 83 near the positioning block 63, and the collar 83 rotates around the connecting shaft 822. Lift the handle 821 slightly, and the handle 82 rotates around the front end of the boss 812, which drives the collar 83 to move forward. Put the collar 83 into the arc portion 631 of the positioning block 63 closest to the front, and then press the handle 821. At this time, the anti-skid pad and the hexagonal nut are pressed tightly, and the first end cover 3 and the second end cover 5 are tightly buckled on the body 4. The hexagonal holes and anti-skid pads on the positioning member 6 and the adjusting member 7 limit the hexagonal nut, and the hexagonal nut is not easy to loosen.

[0057] The device is provided with a locking member 8 that cooperates with the positioning member 6 to clamp the first end cover 3 and the second end cover 5, which can prevent the hexagonal nut from loosening when the air compressor vibrates, and solves the technical problem that the air compressor will vibrate during operation, and long-term use will cause the end cover screws in the air compressor to loosen. Since the air compressor casing is not often opened, the staff cannot discover the problem in time, resulting in reduced performance of the air compressor and easy damage to the air compressor.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
