[0039] An air compressor body 1, an air intake pipe 2 is connected to the upper part of the air compressor body 1;

[0040] The filter element housing 3 comprises a first housing 31, one end of the first housing 31 is fixedly connected to the air inlet pipe 2, the other end of the first housing 31 is plugged with the second housing 32, the inner wall of the first housing 31 is fixedly connected to the first positioning block 33, the inner wall of the second housing 32 is fixedly connected to the second positioning block 34, support blocks 35 are evenly distributed between the first positioning block 33 and the second positioning block 34, and guide cylinders 36 are fixedly connected between the first positioning block 33, the second positioning block 34 and the support block 35, and traction shafts 37 are plugged into the interiors of adjacent guide cylinders 36, and a telescopic guide shaft 38 is connected between the first housing 31 and the second housing 32.

[0041] The driving assembly 4 includes a support frame 41 and a second rack 44. The support frame 41 is fixedly connected to the bottom buffer plate of the air compressor body 1. A pad 42 is fixedly connected to the upper part of the support frame 41. A first rack 43 is arranged above the pad 42. A first gear 46 is meshed with the upper part of the first rack 43. The second rack 44 is fixedly connected to the outer wall of the second shell 32. A second gear 47 is meshed with the lower part of the second rack 44. A guide sleeve 45 is fixedly connected to the outer part of the second rack 44. Through the arrangement of this structure, the first clamping assembly 6 and the second clamping assembly 7 can be driven and controlled, so that when the second shell 32 and the first shell 31 are plugged and approached to each other, the first clamping assembly 6 and the second clamping assembly 7 are driven to work through the transmission drive of the driving assembly 4;

[0042] The first clamping assembly 6 and the second clamping assembly 7 have the same internal structure. The first clamping assembly 6 includes a first worm wheel 61. The first worm 62 is meshed on the outside of the first worm wheel 61. The first gear 46 is fixedly connected to the outside of the first worm 62. The first sliding shaft 63 is slidably inserted into the inside of the first worm wheel 61. The center of the first sliding shaft 63 is fixedly connected to the first guide plate 64. The first clamping plates 65 are fixedly connected at both ends of the first guide plate 64. The first clamping plates 65 are slidably connected to the first support plate 66 on the side close to each other, and the first support plate 66 is fixedly connected to the first worm wheel 61.

[0044] Furthermore, a guide cylinder 36 is fixedly connected to the inside of the side where the first positioning block 33 and the second positioning block 34 are close to each other, and guide cylinders 36 are provided at both ends of the support block 35. A step-type guide hole is opened inside the guide cylinder 36, and both ends of the traction shaft 37 are stepped, and both ends of the traction shaft 37 are inserted into the inside of the guide cylinder 36. The inner diameter of the first positioning block 33 is larger than the inner diameter of the first support plate 66, so that the clamping inner diameter of the first clamping assembly 6 and the second clamping assembly 7 is larger than the outer diameter of the filter element in the non-clamping state, thereby ensuring that after the first shell 31 and the second shell 32 are plugged in, the filter element can be clamped by the first clamping assembly 6 and the second clamping assembly 7.

[0045] Furthermore, the first gear 46 is respectively connected to the two ends of the first worm 62, and the second gear 47 is respectively fixedly connected to the two ends of the second worm 72. The interiors of the first gear 46 and the second gear 47 are both hollow structures, and a metal eccentric block is fixedly connected to the interior of the hollow structure. Through the setting of the metal eccentric block, the center of gravity of the first gear 46 and the second gear 47 is offset, so that when the two are in a non-meshing state, the metal eccentric block is at the lowest end, thereby ensuring the position stability of the first gear 46 and the second gear 47, thereby ensuring their mobile meshing with the first rack 43 and the second rack 44.

The displacement of the pressure plate 52 drives the traction rope 54 to move, thereby pulling the movable shaft 55, and further pulling the positioning gear 57 through the rotating shaft 56. At this time, the positioning gear 57 can be kept away from the inside of the first worm gear 62, thereby ensuring the rotation of the first worm gear 62 and the first gear 46. Conversely, through the elastic control of the second spring 58 and the first spring 53, the positioning gear 57 can be further inserted into the inside of the first worm gear 62, thereby achieving auxiliary limiting of the first worm gear 62 to prevent it from rotating. Through the setting of this structure, after the first shell 31 and the second shell 32 are plugged and sealed, the plug-in positioning of this structure ensures the stability of the plug-in between the first shell 31 and the second shell 32 to avoid loosening later.
