[0027] A shaft retaining ring 2 is provided in the cylinder body 3, and the shaft retaining ring 2 is sleeved on the spline sleeve 1.

[0028] The cylinder body 3 is sleeved with a piston 5 , the piston 5 is provided with a second sealing groove, a second sealing member 7 is arranged in the second sealing groove, and the cylinder body 3 and the piston 5 are sealed by the second sealing member 7 .

[0029] The spline sleeve 1 is provided with a transmission flange 15 , a second bearing 8 is connected between the cylinder body 3 and the transmission flange 15 , a piston inner gear ring 9 is provided on the transmission flange 15 , and the piston inner gear ring 9 is matched with the second bearing 8 .

[0030] The spline sleeve 1 is provided with a second shaft retaining ring 14 , and the spline sleeve 1 is provided with a pressure plate 13 , and the pressure plate 13 is matched with the second shaft retaining ring 14 .

[0032] The working principle of the anti-pin-off type pneumatic clutch provided by the utility model is as follows:

[0033] The first step: driving air pressure enters the air cavity through the cylinder body 3 to push the piston 5 to squeeze the inner tooth friction plate 11, the outer tooth friction plate 12, the reset disc spring 10, the pressure plate 13, the shaft retaining ring 12 and the shaft retaining ring 2 14. The friction between the friction plates can drive the transmission flange 15 to realize the master and slave connection, wherein the shaft retaining ring plays an axial fixing role. When the master and slave are connected and driven, the cylinder body 3 and the piston 5 must not rotate relative to each other, otherwise the seal 1 6 and the seal 2 7 will be damaged. The utility model changes the traditional assembled stop pin into an integral stop block such as Figures 1 to 3 The structure shown in the figure has greatly increased strength, and the axial force generated by the air pressure is not enough to break the brake pad;

[0034] The second step: when the driving air pressure is released, the piston 5, the inner tooth friction plate 11 and the outer tooth friction plate 12 are released back to their original positions under the action of the return disc spring 10, and the force between the friction plate and the transmission flange 15 disappears, realizing the separation of the master and the slave.
