[0045] Working principle of this utility model:

[0046] When the first switch 1 is pressed, the output gear 10 rotates clockwise, as... Figure 5 As shown, due to the resistance between the drive shaft 14 and the elastic rubber sleeve 16, the output gear 10 and the drive shaft 14 will not rotate synchronously at first. At this time, the first spiral groove 22 on the first guide member 11 will force the bearing 19 with the shaft pin 13 to the high limit part 24 (in the initial state, the bearing 19 is located in the low limit part 23, and when the output gear 10 drives the first guide member 11 to rotate, the first spiral groove 22 and the bearing 19 slide). At this time, after the bearing 19 reaches the high limit part 24, it is limited and blocked by the limit post 25. During the sliding movement of the first spiral groove 22 and the bearing 19, the bearing 19 will rotate relative to the shaft pin 13, making the sliding smoother and preventing jamming. After the bearing 19 with the shaft pin 13 slides from the low limit part 23 to the high limit part 24, the drive shaft 14 drives the roller 5 to approach the cutter wheel 8 to clamp the can. Figure 6 As shown, the first guide 11 is continuously driven to rotate without changing the direction of rotation of the output gear 10. The limit post 25 pushes the bearing 19 and the shaft pin 13 to rotate. The shaft pin 13 drives the transmission shaft 14 and the roller 5 to rotate synchronously, thereby driving the can to rotate and complete the opening of the can.

[0047] When the second switch 2 is pressed, the output gear 10 rotates counterclockwise, as shown. Figure 7As shown, due to the certain resistance between the transmission shaft 14 and the elastic rubber sleeve 16, the output gear 10 and the transmission shaft 14 do not rotate synchronously at the beginning, at this time, the first helical groove 22 on the first guide piece 11 forcibly pushes the bearing 19 with the shaft pin 13 to the low position limiting part 23 (in the state of opening the can, the bearing 19 is located at the high position limiting part 24, when the output gear 10 drives the first guide piece 11 to rotate, the first helical groove 22 and the bearing 19 slide), at this time, the bearing 19 is limited by the limiting column 25 after reaching the low position limiting part 23, the first helical groove 22 and the bearing 19 slide, the bearing 19 rotates relative to the shaft pin 13, the sliding is smoother, and the bearing 19 does not appear to be stuck, and after the bearing 19 with the shaft pin 13 slides from the high position limiting part 24 to the low position limiting part 23, the transmission shaft 14 drives the roller 5 to move away from the knife wheel 8, and the can is released.

[0048] It should be noted that the first guide piece 11 and the second guide piece 12 are assembled, the second helical groove 26 and the first helical groove 22 cooperate to form a spiral track, and the bearing 19 must maintain a certain activity gap in the closed spiral track, otherwise it will not work normally.

[0049] The embodiments of the utility model are described above in combination with the drawings, but the utility model is not limited to the above-mentioned specific embodiments, the above-mentioned specific embodiments are only illustrative, but not restrictive, and the person skilled in the art can make many forms under the inspiration of the utility model without departing from the purpose of the utility model and the scope protected by the claims, which all belong to the protection scope of the utility model.
