Furthermore, the number of teeth of the first gear 261 is half of the number of teeth of the second gear 262, the number of teeth of the second gear 262 is half of the number of teeth of the third gear 263, when the driving motor 251 drives the gear box 253 to rotate, and further drives the first gear 261, the second gear 262 and the third gear 263 to rotate, if the driving motor 251 drives the first gear 261 to rotate for 4n, then the number of rotation turns of the second gear 262 is driven to be 2n, and the number of rotation turns of the third gear 263 is driven to be n, and the length of the circumference through which the third gear 263 rotates can be calculated through the number of rotation turns n of the third gear 263 and the angle through which the third gear 263 rotates, which is the displacement through which the pushing piece 200 slides linearly, so that the movement stroke of the pushing piece 200 can be calculated more accurately, and because the pushing piece 200 and the locking bolt 150 are in a linkage relationship, the expansion amount of the locking bolt 150 can be obtained more accurately, and the accurate control of the displacement of the bolt 150 is realized. With this shift design, moreover, the root circle diameters of first gear 261, second gear 262 and third gear 263 are gradually increased, the difficulty of controlling the driving motor 251 can be reduced, specifically, when the driving motor 251 controls the gear box 253 to rotate, so as to drive the first gear 261 to rotate, the number of rotations of first gear 261 is greater than that of second gear 262, and the number of rotations of second gear 262 is greater than that of third gear 263, so that, by controlling first gear 261 to have a rotation for a longer period of time, the defect of the control precision of the driving motor 251 can be overcome, at the moment, the defect of the precision can be overcome by adopting the driving motor 251 with lower precision to rotate for a long time, and the problem that the accumulated error for controlling the movement of the push sheet 200 is increased due to the low precision of the driving motor 251, and then the control on the lock tongue 150 is inaccurate is solved.

Specifically, in the present embodiment, the transmission assembly 252 includes a first transmission gear 254, a second transmission gear 255, a third transmission gear 256 and a fourth transmission gear 257, the second transmission gear 255 and the third transmission gear 256 are coaxially disposed, the first transmission gear 254 is meshed with the second transmission gear 255, the third transmission gear 256 is meshed with the fourth transmission gear 257, and a root circle diameter of the first transmission gear 254 is smaller than a root circle diameter of the third transmission gear 256. In one embodiment, the diameter of the root circle of the first transfer gear 254 is equal to the diameter of the root circle of the second transfer gear 255, the diameter of the root circle of the second transfer gear 255 is one third of the diameter of the root circle of the third transfer gear 256, and the diameter of the root circle of the third transfer gear 256 is one third of the diameter of the root circle of the fourth transfer gear 257. Because the diameter of the root circle of the first transmission gear 254 is consistent with the diameter of the root circle of the second transmission gear 255, the first transmission gear 254 is partially accommodated in the gear box 253, and it is not convenient to directly measure the transmission condition of the first transmission gear 254, therefore, it can be determined whether the transmission connection between the driving motor 251 and the gear box 253 is normal by detecting the number of rotation turns of the second transmission gear 255, that is, the transmission condition in the gear box 253 is led out to the outside of the gear box 253 to be measured, it can be determined whether the power transmission between the driving motor 251 and the gear box 253 has similar errors, if an error occurs, the error can be fed back to the strategy of adjusting and controlling the driving motor 251, so that the closed-loop control with feedback is realized, and the control precision of the driving motor 251 is improved. In the present embodiment, the first transmission gear 254 is rotatably mounted to the gear housing 253, the second transmission gear 255 and the third transmission gear 256 are coaxially disposed and rotatably mounted to the housing 100, and the fourth transmission gear 257 is rotatably mounted to the housing 100. The fourth transmission gear 257 is in transmission connection with the meshing teeth on the pushing piece 200, and the root circle of the fourth transmission gear 257 is directly and relatively large, so that large-area meshing can be formed between the fourth transmission gear 257 and the pushing piece 200, and the stability of connection between the fourth transmission gear 257 and the pushing piece 200 is improved.
With continued reference to fig. 7 and 8, further, the driving motor 251 and the gear box 253 are both installed inside the driving box 270, the driving box 270 is fixedly installed on the housing 100, and a mounting hole is opened on a side wall of the driving box 270 to expose a portion of the gear box 253 for forming a driving fit with the driving assembly 252 outside the driving box 270. The driving box 270 and the housing 100 are detachably connected, and in particular, may be connected by screws. A buffer portion 275 is provided at a connection portion of the driving case 270 and the housing 100 to absorb shock to the driving case 270. Specifically, the buffering portion 275 includes a plurality of first buffering members 276 distributed in a strip shape and a plurality of second buffering members 277 distributed in a circular shape, wherein the plurality of first buffering members 276 distributed in a strip shape are located at the edge of the driving case 270 and the housing 100, the adjacent first buffering members 276 are spaced apart from each other, the spaced distance is smaller than the length of the first buffering members 276, and the size of the plurality of first buffering members 276 is consistent. By arranging a plurality of first buffering members 276 with the same size and dimension at the edge part where the driving case 270 is connected with the casing 100, the effect of balancing stress between the driving case 270 and the casing 100 can be achieved, and the buffering effect on the working process of the driving motor 251 can be achieved. The area size that a plurality of is the second bolster 277 of circular distribution is different, and a plurality of is the middle part that second bolster 277 of circular distribution is located drive box 270 and casing 100 and is connected, and be close to the central point that drive box 270 and casing 100 are connected more, the area that is the second bolster 277 of circular distribution is big more, keep away from the central point that drive box 270 and casing 100 are connected more, the area that is the second bolster 277 of circular distribution is little less, through set up the different second bolster 277 of a plurality of areas in the middle part of drive box 270 and casing 100, and the area that is close to the second bolster 277 that the middle part set up that drive box 270 and casing 100 are connected is greater than the area of keeping away from the second bolster 277 that the middle part set up, can be better play the shock attenuation effect to driving motor 251.
