[0016] With the provided electric cylinder, when the user needs to clamp a screw, the user turns on the electric cylinder through the electric cylinder switch, causing the output shaft of the electric cylinder to drive the auxiliary box to move. Subsequently, the components inside the auxiliary box move, causing the push rod to drive the clamping plate to clamp the bottom of the screw. The anti-slip pad is used to prevent slipping. When the clamping plate clamps the screw, the push rod will be stressed. The stressed push rod will then transmit the force to the stress rod. The stressed stress rod will move downward, causing the damping rod spring to contract. At the same time, the connecting rod is driven by the second hinge seat to deflect downward through the first hinge seat. And the downward movement of the first hinge seat will cause the tension spring to unfold and store energy, giving the push rod a reverse force. Then, this force is transmitted to the clamping plate to achieve the purpose of elastic clamping, thereby helping to enhance the clamping force, ensuring that the screw will not loosen or fall off during processing or assembly, and being able to disperse the pressure during clamping, reducing the direct contact and wear with the screw, thus extending the service life of the fixture and the screw.
