Cap, the upper end of the sub-screw are fixedly connected with rotation axis, and the one end of the rotation axis away from sub-screw is rotatablely connected with interior bar,
By revolute pair nut, make telescopic tube, increase the length of fixing screws entirety, and pass through again after fixing screws taking-up
Secondary nut is rotated backward, shortens telescoping tube, the length reduction of fixing screws entirety is easy to operate, and is not required to sawed-off
Fixing screws.
Preferably, the outside of the cushion pad and buffer stopper scribbles corrosion-inhibiting coating, and corrosion-inhibiting coating makes cushion pad and buffering
Block is not easy to be corroded, and influences to use.
Preferably, the surface of the telescoping tube is coated with scratch resistant layer, and scratch resistant layer makes telescoping tube be not easy to be scratched.
3. advantageous effect
Compared with the prior art, the utility model has the advantage of：
(1) this programme makes telescopic tube, increases the length of fixing screws entirety, Er Qiegu by revolute pair nut
Determine to shorten telescoping tube, the length reduction of fixing screws entirety, operation is very again by rotating backward secondary nut after screw takes out
It is convenient, and it is not required to sawed-off fixing screws.
(2) outside of cushion pad and buffer stopper scribbles corrosion-inhibiting coating, corrosion-inhibiting coating makes cushion pad and buffer stopper be not easy by
Corrosion, influences to use.
(3) surface of telescoping tube is coated with scratch resistant layer, and scratch resistant layer makes telescoping tube be not easy to be scratched.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is structure diagram when the utility model length increases.
Figure label explanation：
1 nut, screw rod, 3 sliding blocks, 4 sliding slots, 5 telescoping tubes, 6 rotation axis, 7 times screw rods, 8 cushion pads, 9 buffer stoppers, 10 on 2

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model；The technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe；Obviously；The described embodiments are only a part of the embodiments of the utility model；Rather than whole
Embodiment.Based on the embodiment in the utility model；Those of ordinary skill in the art are without making creative work
All other embodiments obtained；It shall fall within the protection scope of the present invention.
Embodiment 1：
- 2 are please referred to Fig.1, a kind of adjustable fixing screws of length, including upper screw rod 2, the upper end of upper screw rod 2 is fixedly connected with
Nut 1, the lower end of upper screw rod 2 open up fluted, sliding slot 4 are offered in a pair of sidewalls of groove, the bottom of groove, which is fixed, to be connected
Cushion pad 8 is connected to, interior bar 10 is inserted in groove, the end both sides that interior bar 10 is located in groove have been fixedly connected with buffer stopper 9,
Cushion pad 8 and buffer stopper 9 have cushioning effect when fixing screws are given a shock, their outside scribbles corrosion-inhibiting coating, prevent
Rotten coating makes cushion pad 8 and buffer stopper 9 be not easy to be corroded, and influences to use, and the one end of buffer stopper 9 away from interior bar 10 is fixedly connected with
