The stop rod 1313 is connected to the fixing seat 52 via the elastic pressing component 1314 and abuts against the ratchet 1311. The gear assembly 132 includes a driving gear 1321 and a driven gear 1322 that mesh. The driving gear 1321 is sleeved on the connecting shaft 51 and connected to the ratchet 1311 through the elastic connecting assembly 134.

The elastic connection assembly 134 includes an elastic member (not shown) and a ball disposed in the receiving hole 1341. The balls are pressed between the receiving holes 1341 and the receiving slots 1342 by the elastic member, so that the driving gear 1321 is connected to the ratchet 1311 through the balls.
In some embodiments, the elastic connection assembly 134 may also adopt other mechanisms to connect the ratchet assembly 131 and the gear assembly 132, for example, the connection shaft 51 may be disposed on the elastic recovery assembly, and the connection shaft 51 may drive the driving gear 1321 to move within a small range through the elastic recovery assembly, so that after the material 300 is pushed to the position, the driving gear 1321 may support the teeth on the driven gear 1322 to be away from the driven gear 1322 while rotating, and may engage with the driven gear 1322 again under the action of the elastic recovery assembly after rotating one tooth, but is not limited thereto.
As shown in fig. 5, the base plate 50 is provided with a fixing shaft 53 and a catching groove 54. The middle of the stop rod 1313 is rotatably disposed on the fixed shaft 53, and the stop rod 1313 includes a first end 1315 and a second end 1316.

The ratchet assembly 131 further includes a fixing pin 1318, the fixing pin 1318 is disposed in the through hole 1317, and when the fixing pin 1318 is inserted into the slot 54, the first end 1315 of the stopping rod 1313 abuts against the elastic pressing assembly 1314 to separate the stopping rod 1313 from the ratchet 1311. The feeding operation is conveniently performed after the material 300 is fed, that is, when the stop rod 1313 is separated from the ratchet 1311, the material 300 is sequentially pressed down through the discharge port 112 and loaded into the material storage chamber 111, the material 300 loaded into the material storage chamber 111 pushes the material ejecting member 12 downward to drive the screw 133 to rotate reversely, so that the driven gear 1322 and the driving gear 1321 rotate reversely, the ratchet 1311 rotates reversely under the action of the elastic connecting assembly 134, after the material 300 is filled, the fixing pin 1318 is pulled out of the clamping groove 54, and the first end 1315 of the stop rod 1313 rotates to abut against the ratchet 1311 under the abutting action of the elastic pressing assembly 1314 to complete the feeding. When the fixing pin 1318 is not in the slot 54, the stop rod 1313 can swing left and right under the action of the rotating ratchet 1311 and the elastic pressing component 1314, so that the ratchet 1311 can rotate one tooth at a time, and the ratchet 1311 is prevented from rotating reversely after rotating one tooth.
In some embodiments, the transmission mechanism 13 may also use other mechanisms for converting the driving force, such as cam device or crank-link, but not limited thereto.
