It will of course be appreciated that in other embodiments the actuator 3 may be driven linearly using a linear motor or cylinder or the like.

The working principle of this embodiment is as follows:

as shown in fig. 8, at this time, the check locking protrusion 41 of the first locking member 4 cooperates with the limit slot 221 to lock the piston body 22 in the first position, the driver 3 is powered off and in the initial position, the first driving block 311 is far away from the first locking member 4, the second driving block 321 is far away from the second locking member 5, the rack 6 abuts against the pushing body 222 under the action of the third elastic member 62 and is positioned in the initial position, as shown in fig. 6, at this time, the working surface of the cam 141 is far away from the pressure reducing valve core 12, the pressure reducing valve core 12 is in the valve closing position, and the gas storage container 7 is in the sealed state;

as shown in fig. 9, after the driver 3 is powered on, the iron core is switched from an initial state to a second state through a first state, when the iron core moves to the first state, the first driving block 311 contacts with the first locking piece 4 and pushes the first locking piece 4 upwards, so that the check card protrusion 41 is withdrawn from the limit clamping groove 221, after the effect of the check card protrusion 41 is lost, the piston body 22 moves from the first position to the second position under the effect of the first elastic piece 23, in the moving process of the piston body 22, the pushing body 222 abuts against the rack 6 and pushes the rack 6 to the locking position, in the moving process of the rack 6 from the initial position to the locking position, the driven gear 13 is driven to rotate, the transmission shaft 14 synchronously rotates along with the driven gear 13, the working surface of the cam 141 acts on the pressure reducing valve core 12, so that the pressure reducing valve core 12 is in the valve opening position, and at this time, the gas storage container 7 is opened and supplies gas to the gas channel 24, as shown in fig. 7; when the iron core moves to the second state, the second driving block 321 contacts with the second locking piece 5 and pushes the second locking piece 5 upwards, so that the positioning column 51 is inserted into the locking hole 61, thereby locking the rack 6 at the locking position, and the pressure reducing valve core 12 is kept at the valve opening position;

as shown in fig. 7 and 10, when the pressure reducing valve core 12 is in the valve opening position, part of the gas in the gas storage container 7 enters the cylinder 21 through the gas channel 24, the gas pressure in the cylinder 21 is gradually increased to press the piston body 22 back to the first position, when the piston body 22 is restored to the first position, the check card protrusion 41 of the first locking piece 4 stretches into the limit card groove 221, the piston body 22 is locked in the first position through the cooperation of the check card protrusion 41 and the limit card groove 221, and at this time, the pushing body 222 moves along with the piston body 22 and is far away from the rack 6;

after the driver 3 is accidentally powered off or normally used, the driver 3 is powered off at this time, the iron core is switched from the second state to the initial state through the first state, when the iron core is separated from the second state, the second locking piece 5 makes the positioning column 51 separate from the locking hole 61 under the action of the fourth elastic piece 52, the rack 6 is reset to the initial position under the action of the third elastic piece 62 and is in contact with the pushing body 222, the rack 6 moves to drive the driven gear 13 to rotate, the transmission shaft 14 synchronously rotates with the driven gear 13, the working surface of the cam 141 is far away from the pressure reducing valve core 12, the pressure reducing valve core 12 is in the valve closing position, and the air container 7 is closed again at this time, as shown in fig. 6; when the iron core moves to the first state, the first driving block 311 makes the check card protrusion 41 separate from the limit card slot 221, but since the air pressure in the cylinder 21 is greater than the elastic force of the first elastic member 23, the piston body 22 is still at the first position, and when the iron core moves to the initial state after the first state is switched, the check card protrusion 41 stretches into the limit card slot 221 again to lock the piston body 22 at the first position, and finally the embodiment is reset to the initial state as shown in fig. 8.

In addition to the preferred embodiments described above, other embodiments of the present utility model are also contemplated as falling within the scope of the claimed utility model, as well as all other embodiments that may be made by one of ordinary skill in the art without making any inventive effort based on the embodiments of the present utility model.
