The present invention will be described in detail below.

The utility model discloses a be equipped with attenuator body 5, attenuator tailstock 6 in the card arm 4, the appearance of attenuator tailstock 6 is the cylinder, and one end is equipped with one-way open-ended cylindrical cavity, and the one end of attenuator body 5 is inserted and is fixed in the cylindrical cavity of attenuator tailstock 6, both interference fit. As shown in fig. 5, the other end of the damper tailstock 6 comprises an inner concave surface 63 and a tail hook 61 protruding from the tailstock 6, the inner concave surface 63 and the tail hook 61 together form a notched circular shape, and the inner concave surface 63 is actually a cylindrical surface which smoothly extends and transitions towards the tail hook 61. The damper tailstock 6 and the tail hook 61 are integrated, are made of plastic and are suitable for mass injection production.

The tail hook 61 is buckled on the first fixing hinge pin 71, the tail hook 61 is hinged with the first fixing hinge pin 71, namely the cylindrical surface of the tail hook is matched and assembled with the cylindrical surface of the first fixing hinge pin 71, two ends of the first fixing hinge pin 71 penetrate through the clamping arm 4, holes larger than the first fixing hinge pin 71 are formed in two sides of the clamping arm 4, the first fixing hinge pin 71 can easily penetrate through the holes, and two ends of the first fixing hinge pin 71 are fixedly installed on the fixing arm 2.

The other end of the damper body 5 is provided with a piston rod 51 for providing damping when being pressed toward the damper body 5, and particularly, when the piston rod 51 is pulled out, the resistance is very small, the internal structure of the piston is the conventional art which has been disclosed so far, and the description thereof will not be described in detail. The front end of the piston rod 51 is sleeved with a plastic hook head 52 in an interference fit manner, the hook head 52 is buckled on a first hinge pin 91 of the pressure arm mounted on the pressure arm 9, and the hook head 52 is hinged with the first hinge pin 91 of the pressure arm, that is, the hook head 52 can rotate around the first hinge pin 91 of the pressure arm.
