Embodiment Construction
[0016] Now in conjunction with the accompanying drawings, the structure of the present invention will be further described. Such as Figure 1-Figure 5 As shown, the device includes spring seat 1, roller sleeve 2, fixed hanging spring shaft 3, closing spring 4, elastic cylindrical pin 5, buffer sleeve 6, energy storage crank arm 7, guide roller 8, guide plate 9, hexagonal locking The nut 10, the guide plate and the buffer sleeve are combined into a whole through elastic cylindrical pins. The closing springs at both ends of the guide plate are respectively limited to the spring seat, and the spring seat is respectively provided with a roller sleeve and a guide roller. The spring seat at the end of the roller sleeve, the guide plate and the fixed hanger The spring shaft is connected, and the spring seat and the guide plate at the end of the guide roller are connected with one end of the energy storage arm. One end swings as the center of rotation to realize telescoping. Simulta...
