[0024] A power rod 10 is rotatably arranged in the housing 3, and the upper end of the power rod 10 is meshed with the power output end of the motor 4, and the power rod 10 is driven to rotate by the motor 4. A matching rod 11 is also arranged in the housing 3, and a special-shaped opening is arranged on the matching rod 11. The power rod 10 is movably inserted into the matching rod 11 through the special-shaped opening. The special-shaped opening includes but is not limited to a straight opening, a cross opening, and a star-shaped opening. The power rod 10 can drive the matching rod 11 to rotate together, and a pressure plate 12 is rotatably arranged on the surface of the matching rod 11;

A spring is provided at the upper end of the twisting end 14, and a stop plate is fixedly provided in the distributing rod 11, and the stop plate is located above the spring. Under normal conditions, the twisting end 14 is located at the lowest point of the strip groove. When the twisting end 14 is subjected to an upward force, the twisting end 14 transmits the force to the spring, and the upper and lower ends of the spring are in contact with the twisting end 14 and the stop plate respectively. The spring deforms and contracts, so that a part of the twisting end 14 contracts in the distributing rod 11. When the force disappears, the twisting end 14 is reset;

[0026] Specifically, gas is injected through the gas injection channel 15, and the pressure plate 12 is moved downward together with the displacing rod 11 by the action of the gas. During the movement, the power rod 10 is always in the displacing rod 11, so that it is convenient for the motor 4 to adjust the power rod 10 to rotate with the displacing rod 11. When the displacing rod 11 moves, the twisting end 14 on the displacing rod 11 will contact the screw on the clamp 9 and exert a downward force on the screw, so that the clamp 9 is opened.
