Refer to Figure 2 and Figure 3 for its cross-sectional structure and disassembled views of its internal structure.

The specific function realization part includes the knocking unit and the feeding unit.

The knocking unit includes a knocking rod and a driving part that drives the knocking rod to strike forward. The knocking rod is connected with a spring, and the driving part is used to drive the knocking rod to slide backward to compress the spring. After the compression reaches the limit, the driving part is released The sliding limit of the knocking bar releases the potential energy of the spring, so that the knocking bar is knocked forward.

Referring to Fig. 2, Fig. 4 and shown in Fig. 5; the driving part is the rotating column 31 driven by the motor 3, the rotating column 31 is a hollow structure, the rotating column 31 is provided with a slide bar 310, and the knocking bar is slidably connected on the slide bar 310 , and the rotating column 31 is sleeved on the outer peripheral surface of the knocking rod, the outer peripheral surface of the knocking rod is provided with a cam groove and a straight groove communicating with the cam groove, and the inner wall of the rotating column 31 is provided with a boss 311, the boss When 311 is accommodated in the cam groove, the rotating column rotates. Under the limit of the cam groove, the knock rod is driven to slide back and forth. At the end of a stroke, the convex post 311 enters the straight groove, and the straight groove is arranged along the elastic direction of the spring.

Referring to Fig. 2, the knocking rod is made up of two separate parts of the knocking column 34 and the power column 33, the cam groove 330 and the straight groove 331 are arranged on the power column, the power column 33 is driven, and the knocking column 34 is arranged on the power column. The front end of the column 33, when the power column 33 is impacted by the potential energy of the spring, will transmit the impact force to the knocking column 34, and the knocking column 34 will push the gasket out.

Referring to Fig. 5 and Fig. 6, both ends of the straight groove 331 and the cam groove 330 are connected. In the initial state, the protruding post 311 of the power post 33 is located at one end of the two slots, the rotating post 31 rotates, and the protruding post 311 Entering into the cam groove 330, under the limitation of the cam groove 330, push the power column 33 to slide. When the rotation limit is reached, that is, when the protruding post 311 reaches the other end hinge of the two grooves, the protruding post 311 enters the straight groove 331. The limit is released, and under the action of the spring (the elastic direction of the spring is consistent with the extending direction of the straight groove 331), the power column 33 slides back to the initial state.

Further, a conical spring 300 is provided at the connection of the knocking post 34 , one end of the conical spring 300 is in contact with the casing, and the other end of the conical spring 300 is in contact with the striking post 34 .

Then add a spring 302 to help the balance post 35 reset at the rear end of the balance post 35 .

During specific work, the rotating column 31 rotates, the power column 33 retracts, and the balance column 35 advances, and the two compress the middle cylindrical spring 301. Both enter the straight groove, and the two columns slide towards each other;

The function of the balance column 35 is to maintain the running balance of the driving system of the rotating column 31 . Because the rotating column 31 is installed in the housing, if only one end of the rotating column 31 is stressed, its structure will inevitably deviate after a long time of use. And increase balance column 35, make its two ends adopt convex column drive, carry out force, bear force and keep balance. At the same time, the movement of the balance column 35 can also neutralize the impact of the power column 33 on the shell as much as possible.
