[0032] Working principle:
[0033] When in use, first turn on the power supply, the motor 22 starts, and drives the rotating shaft 21 connected thereto to rotate, and drives the rotating pin 1 321 to perform a circular motion through the turntable 2, thereby driving the connecting rod 32 to reciprocate up and down.

During the operation of the device, the shock-absorbing rubber block 4, the rubber seat 421 and the anti-skid pad 42 work together to provide stable support for the inner shell 11 of the acupuncture machine, and have anti-skid and certain shock-absorbing effects, thereby reducing the vibration of the inner shell 11 of the acupuncture machine during the pile-raising process of the needle plate 3. In addition, the shock-absorbing rubber block 4, the rubber seat 421 and the anti-skid pad 4 2 can also greatly reduce the noise generated during the operation of the device and transmit it downward to the ground. The arrangement of the damping spring 5 and the damping rod 51 can provide a buffer between the inner shell 11 and the outer shell 1 of the needling machine, thereby reducing the influence of the vibration generated by the needle plate 3 during the raising process. At the same time, the porous sound-absorbing layer 12, the low-frequency sound-absorbing layer 13 and the high-frequency sound-absorbing layer 14 are used in combination to expand the sound absorption range and improve the sound absorption coefficient, which can effectively absorb and reduce the noise generated during the operation of the device. In addition, the rubber plate 24 and the support seat 23 are used in combination to provide support for the left rotating shaft 21 and reduce the noise generation to a certain extent. The silent bearing 33 provided in the through-holes opened on the turntable 2 and the hinge block can reduce the noise generated during the transmission process. The entire device has a simple structure, is easy to operate, has a good vibration reduction and noise reduction effect, and is highly practical.
