One side of the rotating threaded block 6 away from the fixed rod 1 is rotatably connected with an extension rod 4. One side of the extension rod 4 away from the fixed rod 1 is fixedly connected with a fixed clamping ring 14. The top of the fixed clamping ring 14 is connected with a movable clamping ring 15 through a hinge. The inner sides of the fixed clamping ring 14 and the movable clamping ring 15 are both fixedly connected with rubber shock-absorbing pads 16. Inside the rubber shock-absorbing pads 16 is arranged a copper rod 17. The fixed clamping ring 14 and the movable clamping ring 15 are internally threadedly connected with a second bolt 18. The outer side of the second bolt 18 is threadedly connected with a nut 19. By providing the threaded rod 2, the rotating threaded block 6 and the extension rod 4, it is possible to facilitate the movement of the extension rod 4 to the required position by rotating the rotating threaded block 6 on the outer side of the threaded rod 2 according to the usage needs, so as to facilitate the staff to carry out extended use, and thus make the use performance of the device more extensive; by providing the fixed clamping ring 14, the movable clamping ring 15, the rubber shock-absorbing pad 16, the copper rod 17, the second bolt 18 and the nut 19, it is possible to facilitate the clamping and fixing of the copper rod 17 by using the fixed clamping ring 14 and the movable clamping ring 15, and the second bolt 18 and the nut 19 can be used to reinforce the clamping of the copper rod 17, and the rubber shock-absorbing pad 16 can provide shock protection to prevent the shock force during knocking from causing damage to the user.
[0026] One side of the fixed rod 1 is fixedly connected with a handle 20 to facilitate the user to hold the device; the outer side of the handle 20 is fixedly connected with an anti-slip corrugated soft pad 21, which can provide friction and protection through the anti-slip corrugated soft pad 21 when the user holds the handle 20; both sides of the extension rod 4 are fixedly connected with first fixing blocks 7. Both sides of the fixed rod 1 are fixedly connected with second fixing blocks 8. One side of the first fixing block 7 and inside the second fixing block 8 is fixedly connected with a first limiting rod 9, which can guide and limit the extension rod 4; the first limiting rod 9 is slidably connected with the second fixing block 8. One end of the first limiting rod 9 away from the first fixing block 7 is fixedly connected with a second limiting block 10. Inside the fixed rod 1 is provided a limiting groove 11 that cooperates with the second limiting block 10, which can enable the second limiting block 10 to slide in the limiting groove 11 for guiding and limiting; the inside of the second limiting block 10 is threadedly connected with a first bolt 12. Inside the fixed rod 1 are provided a plurality of threaded holes 13 that cooperate with the first bolt 12. The position of the extension rod 4 can be reinforced by the cooperation of the first bolt 12 and the plurality of threaded holes 13; one side of the threaded rod 2 away from the fixed rod 1 is fixedly connected with a first limiting block 3. Inside the extension rod 4 is provided a first sliding groove 5 that cooperates with the first limiting block 3, which can play a role in guiding and limiting when moving the extension rod 4.
[0027] Specifically, when using the copper rod 17, it is placed into the fixed clamping ring 14 and the movable clamping ring 15. The rubber shock pad 16 is closely attached to the copper rod 17. Then, the movable clamping ring 15 is flipped through the hinge and combined with the fixed clamping ring 14. The second bolt 18 is used to fix the fixed clamping ring 14 and the movable clamping ring 15, and then the nut 19 is used to fix the second bolt 18. When it is necessary to extend the using position of the copper rod 17, first rotate the first bolt 12 to take it out, and then rotate the rotating threaded block 6 to rotate within the extension rod 4, so that the rotating threaded block 6 moves on the outside of the threaded rod 2, thereby driving the extension rod 4 to slide on the outside of the threaded rod 2. The first limiting block 3 can limit the extension rod 4. When the extension rod 4 moves away from the fixed rod 1, the first fixing blocks 7 on both sides of the extension rod 4 drive the first limiting rod 9, so that the first limiting rod 9 slides within the second fixing block 8. And when the first limiting rod 9 moves, it drives the second limiting block 10 to slide within the limiting groove 11. The cooperation between the limiting groove 11 and the second limiting block 10 realizes the limiting. After moving the copper rod 17 to the required position, the first bolt 12 and the threaded hole 13 are used to cooperate to fix the position of the second limiting block 10, thereby strengthening the position of the extension rod 4. After that, one can hold the outer anti-slip corrugated soft pad 21 of the grip 20. The anti-slip corrugated soft pad 21 can reduce vibration and increase the friction force, thereby providing protection for the user.
