The diameter of the high-pressure air outlet hole (13) is 1-2 mm.

The utility model discloses a theory of operation:

(a) the operating principle of the actuating mechanism is as follows: when the vibration mechanism works, high-pressure air enters the central rod (5) from the right air inlet (1) and reaches the air supply hole (16) of the central rod, and the piston (9) in the hollow cavity reciprocates left and right in the actuating mechanism body (8) under the action of the high-pressure air to generate vibration force. When the piston (9) is at the leftmost working position, the left air inlet channel A (15) is communicated with the air supply hole (16) of the central rod, and the right working cavity (18) is communicated with the outside through the right exhaust hole (7) without pressure; high-pressure air enters the left working chamber through the internal pipeline of the left air inlet channel A (15), and pushes the piston (9) to move rightwards along with the increase of the pressure in the left working chamber; when the left end surface of the piston (9) runs to be tangent to the left side of the left exhaust hole (10) and communicated with the atmosphere, the left working chamber finishes working, high-pressure gas in the left working chamber is sprayed out from the left exhaust hole (10), and the piston (9) continues to run rightwards for a certain distance under the action of inertia; the piston (9) continues to move rightwards, when the right end face of the piston gradually seals and closes the right exhaust hole (7), meanwhile, a right air inlet channel B (17) of the piston (9) is communicated with an air supply port (16) of the center rod, high-pressure air enters a right working chamber through an inner pipeline of the right air inlet channel B (17), and the piston (9) is pushed to move leftwards. The piston (9) reciprocates in the actuating mechanism body (8) repeatedly in this way, and high-frequency axial vibration force is generated to provide axial power for working parts arranged on the actuating mechanism body.

(b) The working principle of the auxiliary starting air passage is as follows: when the actuating mechanism is not started to work, when the piston (9) is in the middle position of the actuating mechanism body (8), the piston left air passage A (15) and the piston right air passage B (17) are not communicated with the air supply hole (16) of the central rod, so that the actuating mechanism body cannot be started to work normally when in the horizontal position; therefore, an auxiliary starting air passage is designed and consists of a left air duct (19), a marble (20), a marble working cavity (21) and a right air duct (22), and a proper gap is reserved between the marble (20) and the left air duct (19) and between the marble and the right air duct (22) to form the marble working cavity (21) which is communicated with the air supply hole (16) of the center rod; when the piston (9) is in the middle position, high-pressure gas enters the gas supply hole (16) of the central rod to the marble working cavity (21), the marble (20) is pushed to move leftwards to close the left gas guide pipe (19), the high-pressure gas enters the right working cavity (18) through the right gas guide pipe (22), the high-pressure gas pushes the piston (9) to move leftwards, when the left gas passage A (15) of the piston is communicated with the gas supply hole (16) of the central rod, the high-pressure gas enters the left working cavity to push the piston to move rightwards, and the gas passage is started to finish working in an; similarly, when the piston (9) is in the middle position, high-pressure gas enters the central rod gas supply hole (16) to the marble working cavity (21), the marble (20) is pushed to move rightwards to close the right gas guide pipe (22), the high-pressure gas enters the left working cavity (14) through the left gas guide pipe (19), the high-pressure gas pushes the piston (9) to move rightwards, when the piston right gas passage B (17) is communicated with the central rod gas supply hole (16), the high-pressure gas enters the right working cavity, the piston (9) is pushed to move leftwards, and the auxiliary starting gas passage finishes working. When the piston (9) normally works, because pressure difference exists between the left working cavity (14) and the right working cavity (18), the pressure difference is transmitted to the marble (20) through the air duct, the marble (20) can synchronously close the left air duct (19) and the right air duct (22) along with the left-right movement of the piston, and the left working cavity (14) is not communicated with the right working cavity (18).
