[0010] A core shaft column is also installed on the upper surface of the magazine at one side of the guide rod, and an eccentric wheel is mounted on the core shaft column. Two lift arm pins are rotatably mounted on the eccentric wheel through rolling bearings, and one end of the core shaft column is mounted with a driven gear that is meshed with one of the gears in the speed gear set.

[0011] Preferably, the speed change gear set comprises a plurality of gears, and the plurality of gears are meshed and connected in pairs.

[0012] Preferably, the top of the neutral frame is in a U-shaped structure, the striking arch rod is in an L-shaped structure, and the bending part of the striking arch rod is engaged between the two vertical ends of the neutral frame.

[0013] Preferably, a sliding groove is provided on the surface of the striking arch rod, and the sliding groove is provided along the length direction of the striking arch rod. The lift block pin is engaged in the sliding groove and can slide in the sliding groove.

[0049] The driving mechanism includes a motor 1 and a speed-changing gear set 2, wherein the output shaft of the motor 1 is connected to one of the gears in the speed-changing gear set 2;

[0050] A core shaft column 10 is also installed on the upper surface of the magazine 14 at one side of the guide rod 5. An eccentric wheel 17 is provided on the core shaft column 10. Two lift arm pins 9 are rotatably installed on the eccentric wheel 17 through a rolling bearing 18. One end of the core shaft column 10 is provided with a driven gear that is meshed with one of the gears in the speed gear set 2. The speed gear set 2 is located inside the gearbox case.

[0051] The speed change gear set 2 comprises a plurality of gears, and the gears are meshed and connected in pairs.

[0052] The neutral frame 15 has a T-shaped structure, and the bottom of the power spring 11 is mounted on the horizontal end of the neutral frame 15 .

[0053] The top of the neutral frame 15 is in a U-shaped structure, and the striking arch rod 4 adopts an L-shaped structure. The bending part of the striking arch rod 4 is engaged between the two vertical ends of the neutral frame 15.

[0054] A sliding groove is provided on the surface of the striking arch rod 4 , and the sliding groove is provided along the length direction of the striking arch rod 4 . The lift block pin 7 is engaged in the sliding groove and can slide in the sliding groove.

[0055] A sliding groove 16 is provided on the top of the firing pin seat 3 along the width direction, and a sliding pin 6 is installed on the side of one end of the striking arch rod 4, and the sliding pin 6 is engaged in the sliding groove 16.

[0056] Motor 1 is a DC18V motor.

[0057] In combination with Examples 1 to 4, it can be seen that in the present invention, the lift arm pin 9 is installed with a rolling bearing 18. Such a structural arrangement enables the eccentric wheel 17 to rotate synchronously around the core shaft column 10 when the speed gear set 2 is rotating, so that the lift arm pin 9 rotates around the core shaft column 10. When the lift arm pin 9 rotates to the bottom of the lift block 8, the lift arm pin 9 can drive the lift block 8 to rise. When the eccentric wheel 17 continues to rotate until the lift arm pin 9 moves out from under the lift block 8, the lift arm pin 9 and the lift block 8, that is, the striking arch rod 4, are disengaged. Such a structural arrangement ensures that the striking arch rod 4 will not produce a collision and energy loss when it is disengaged, thereby ensuring the striking force.

[0058] In the present invention, a sliding groove 16 is provided on the top of the firing pin seat 3 along the width direction, and a sliding pin 6 is installed on the side of one end of the striking arch rod 4. The sliding pin 6 is engaged in the sliding groove 16. Such a structural arrangement allows the sliding pin 6 to slide in the sliding groove 16 during the rising and falling striking process of the striking arch rod 4, so that the firing pin seat 3 can always be vertically downward, thereby ensuring the firing pin effect.

[0059] In the present invention, the working spring 11 is set as a rear-mounted structure, that is, the striking arch rod 4 is set as an L-shaped structure, the bending part of the striking arch rod 4 is rotatably installed on the top of the neutral frame 15, the working spring 11 is located at one end of the striking arch rod 4, and the firing pin seat 3 is located at the other end of the striking arch rod 4. Such a lever structure enables the striking arch rod 4 to increase the stroke of the firing pin seat 3 when driving the firing pin seat 3 to inject, thereby greatly improving the injection force and ensuring the high efficiency of the strike. Moreover, this rear-mounted working spring 11 structure setting prevents the eccentric wheel 17 from colliding and causing energy loss when it is disengaged, thereby ensuring the striking force.

[0060] Working principle, see Figure 1-5When the device is in use, the motor 1 starts to run, driving the speed change gear set 2 to rotate. Since the speed change gear set 2 is meshed with the driven gear on the core shaft column 10, the eccentric wheel 17 can rotate synchronously around the core shaft column 10, and the lifting arm pin 9 also rotates around the core shaft column 10. When the lifting arm pin 9 rotates to the bottom of the lifting block 8, the lifting arm pin 9 can drive the lifting block 8 to rise. At this time, the end of the striking arch rod 4 close to the firing pin seat 3 is lifted upward, and the working spring 11 is compressed. When one end of the striking arch rod 4 reaches the maximum height, the lifting arm pin 9 moves out from under the lifting block 8, and the lifting arm pin 9 is separated from the lifting block 8. At this time, the striking arch rod 4 is lifted away from one end of the firing pin seat 3 by the elastic force of the working spring 11, and the lever is moved away, and the firing pin seat 3 is moved downward to complete the firing pin. The above steps are repeated to achieve a continuous firing pin process.

[0061] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
