[0007] Preferably, the side of the mounting seat is provided with an air inlet, the mounting seat has an air inlet channel, the air inlet channel communicates the cavity one between the piston and the mounting seat with the air inlet, the cavity two formed by the piston and the cylinder body has a corresponding exhaust hole and exhaust channel, and a reset spring is arranged between the piston and the cylinder body.

[0008] Preferably, the mounting seat has a cavity three, the cavity three is communicated with the cavity one, and the side of the piston close to the mounting seat is provided with a protrusion corresponding to the cavity three.

[0009] Compared with the prior art, the utility model has the advantages that:

[0010] The air cylinder is mounted on the support through the fixed plate at the bottom end of the mounting seat, when the air cylinder is repaired, the cylinder body can be dismounted and repaired by only removing the bolt between the butt joint plate one and the butt joint plate two at the waist, so that the operation is simple and the repair is convenient.

[0020] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Unless otherwise specified, the raw materials and equipment used are commercially available or commonly used in the art. The methods in the embodiments, unless otherwise specified, are conventional methods in the art. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0021] A cylinder convenient to overhaul, comprising mutually opposite mounting seat 5 and cylinder body 2, the center of mounting seat 5 vertically through and slidingly arranged movable rod 1, the bottom end of movable rod 1 is connected sealing plug, the part of movable rod 1 in cylinder body 2 is connected piston 7, the opposite port of cylinder body 2 is outwardly folded to form butt plate one 3, the opposite port of mounting seat 5 is outwardly folded to form butt plate two 4, butt plate one 3 and butt plate two 4 are bolted, and butt plate one 3 and butt plate two 4 are located in the middle section of the whole cylinder, the end of mounting seat 5 away from cylinder body 2 is provided with fixed plate 6 for fixing the cylinder itself, and fixed plate 6 is provided with bolt hole; the side of mounting seat 5 is provided with air inlet 51, and mounting seat 5 has air inlet channel 52, air inlet channel 52 communicates cavity one between piston 7 and mounting seat 5 with air inlet 51, cavity two formed by piston 7 and cylinder body 2 has corresponding exhaust hole 121 and exhaust channel 122, reset spring is arranged between piston 7 and cylinder body 2 above piston 7; mounting seat 5 has cavity three in the inside, cavity three is communicated with cavity one, and the side of piston 7 close to mounting seat 5 is provided with protrusion corresponding to cavity three.
