[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] Referring to Figures 1-4 , tightener release and recovery device, including outer rod 1 and inner rod 2, the inside of outer rod 1 is set with the cavity 15 that passes through, and one end of outer rod 1 is fixedly set with rear claw 12, and the other end of outer rod 1 is fixedly set with outer handle 11. Inner rod 2 is adapted to move in cavity 15, and one end of inner rod 2 is fixedly set with front claw 22, and the other end of inner rod 2 is fixedly set with inner handle 21, and inner handle 21 is stretched out from cavity 15 and located in the inside of outer handle 11.

[0021] Wherein, both ends of inner rod 2 are stretched out from cavity 15, and one end of inner handle 21 set up on inner rod 2 is close to outer handle 11, and one end of front claw 22 set up on inner rod 2 is close to rear claw 12.

[0022] The outer rod 1 is fixedly provided with a reinforcing rod 14, and the other end of the reinforcing rod 14 is fixedly connected with the rear claw 12. Through the arrangement of the reinforcing rod 14, the stability of the rear claw 12 during use can be improved, so as to improve the service life of the device.

[0023] The end of the rear claw 12 is fixedly provided with an inclined rod 13, the inclined rod 13 is inclined towards the front claw 22, and the inclination angle of the inclined rod 13 is 20°. Through the arrangement of the inclined rod 13, the device can be easily taken back by the operator after the tightening is completed, so that it will not be stuck on the wire clamp, so as to reduce the requirement of the wrist strength of the operator.

[0024] The end of the front claw 22 is fixedly provided with a flat rod 23, the flat rod 23 is matched with the inclined rod 13, and the outer walls of the inclined rod 13 and the flat rod 23 are both sleeved with anti-skid sleeves.

[0025] When the inner handle 21 is pulled backward, the front claw 22 moves to the rear claw 12, and when the inner handle 21 is pushed forward, the front claw 22 moves away from the rear claw 12.

[0026] In this embodiment, when the device is used to release the wire tightener, the user needs to insert the movable front claw 22 into the upper end of the wire clamp, and the rear claw 12 is inserted into the tail end ring of the wire clamp. Then the operator pulls the inner handle 21 backward, at this time the distance between the front claw 22 and the rear claw 12 is large, the device is in an open state, and then the device is used to slide the wire clamp along the wire to the specified position.

[0027] Further, when the user needs to use the device to recycle the wire tightener, the above operation is repeated, and the device is pulled back along the wire. Through the arrangement of the inclined rod 13, the problem that the operator cannot take back the wire after tightening can be solved, so that the operator can quickly and easily release and recycle the wire tightener.

[0028] Further, since the device is a movable device, the middle section adopts a cylindrical outer rod 1 and an inner rod 2, so that the operation strength can be achieved, and the overall device is not too heavy, thereby reducing the weight of the overall device. And the device considers the length of the hands and the height of the ordinary people, and the design length of the inner rod 2 is 510mm.

[0029] Further, the main material of the device is made of steel pipe and steel bar, the outer rod 1 and the outer handle 11 are connected by welding, and the inner rod 2 and the inner handle 21 are connected by welding. The material of the device is iron, the weight is 300-350g, the maximum extension stroke is 10cm, and the device can meet the operation of various types of wire tightener.

[0030] Further, the installation time of the wire clamp is shortened from an average of 31.67 minutes to an average of 24.67 minutes, with an average reduction of 7 minutes, saving operation time. This not only greatly shortens the time for on-pole operation and fault handling, but also reduces the number of ground support personnel, reduces the risk of high-altitude operation, and increases operation efficiency.

[0031] In the utility model, the inner handle 21 is pushed and pulled to control the inner rod 2 to move inside the outer rod 1, so that the distance between the rear claw 12 and the front claw 11 can be adjusted, the device can release the tightener, the inclined rod 13 arranged at the end of the rear claw 12 can solve the problem that the tightener is not convenient for the operator to take back after being tightened, and the operation efficiency of the operator on the tightener can be improved, so that the operator can use the device conveniently.

[0032] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
