The ejector rod abuts against the wall surface of the guide rail due to self weight, the driven wheel also keeps a static state, the swing block of the driven wheel is contacted with the second ejector rod, and at the moment, the ejector rod is completely separated from the driven wheel and the driving wheel, so that the actions are not influenced mutually; if the guide rail falls, the ejector rod abuts against the wall surface of the guide rail due to the dead weight and is immediately blocked when meeting the gap of the guide rail, so that the guide rail is prevented from continuously falling; an eccentric spring is additionally arranged to improve the blocking speed of the mandril. The guide rail descends vertically downwards slowly at a constant speed to drive the driving wheel to rotate anticlockwise, the clamping blocks descend to the lowest point of the first groove under the action of self gravity, and the driven wheel keeps still at the moment.
The position of the vertical plane where the second rotating shaft is located and the base are crossed is a vertical line in the vertical direction, one end of the spring is connected to the position, corresponding to the vertical line, on the base, and the eccentric spring is in a tensioning state constantly. When the eccentric spring is arranged, the ejector rod deviates from the wall surface of the guide rail due to the tensile force of the spring and is not contacted when the guide rail descends, the driven wheel also keeps static, the swing block is contacted with the end part of the second ejector rod (or is close to a small gap), and at the moment, the ejector rod is separated from the driven wheel and the driving wheel, so that the actions are not influenced mutually.
The guide rail vertically and rapidly drops to drive the driving wheel to rotate anticlockwise, the driving wheel rotates at an accelerated speed, and under the action of centrifugal force, the clamping block extends the first groove to move outwards and is tightly attached to the inner wall of the second groove to drive the driven wheel to rotate. When the driven wheel swing block contacts the highest point of the ejector rod, the head of the ejector rod is not in complete contact with the guide rail. The swing block of the driven wheel can continue to rotate along with the driving wheel. When the push rod starts to rotate under the action of the driven wheel swing block. After rotating a certain angle, the ejector rod rotates anticlockwise at an accelerated speed under the action of self gravity and/or an eccentric spring, the head of the first ejector rod abuts against the guide rail, the guide rail continuously drops, and the head is clamped in the gap. If an over-center spring is present, it accelerates its deflection towards the guide rail.
