[embodiment]
The utility model is made below in conjunction with the accompanying drawings further explained below：
As shown in drawings, the utility model includes：Wire frame 1, tension disc 2, spring 3, cam lever 4 and support 5, connect
Wire frame 1, tension disc 2, cam lever 4 are installed in support 5, and the top of support 5 offers groove 501, and groove 501 is longitudinally arranged,
The top of tension disc 2 is inserted into groove 501, and the bottom of support 5 is provided with axial trough 502, and axial trough 502 is arranged along the horizontal, the bottom of cam lever 4
Portion is in axial trough 502, and cam lever 4 is arranged on the bottom of wire frame 1, wire frame 1 under the drive of cam lever 4 upwards or to
Lower motion, the bottom of tension disc 2 are arranged in wire frame 1, linked between the bottom of tension disc 2 and the top of wire frame 1 by spring 3
Together.
Wherein, the bottom of tension disc 2 is provided with the line-ball tongue for being used for pushing down wire, and line-ball tongue is in the inside of wire frame 1, and
And small range rotation can be done by the top of tension disc 2, it is linked together between tension disc 2 and wire frame 1 by spring 3, and
And it be able to can be done relative motion between wire frame 1 and tension disc 2 in the case of with the active force of spring force is overcome；It is convex
Cam 401, salient angle 402 and lever spanner 403 are provided with turbine/lever 4, cam 401 is arranged on the bottom of lever spanner 403, convex
On the cam 401, cam lever 4 is arranged on the bottom of wire frame 1 at angle 402, and the lower surface 101 of wire frame 1 directly withstands on convex
On wheel 401, the bottom of wire frame 1 is additionally provided with the hook 102 and elongated square hole 103 of " L " shape, and hook 102 coordinates with salient angle 402
Connection, cam 401, salient angle 402 rotate with lever spanner 403 drives wire frame 1 to be moved upwardly or downwardly respectively, is specially：It is convex
The rotation of turbine/lever 4 can up be pushed up wire frame 1 by cam 401, can also opposite direction rotate, driven by salient angle 402
Wire frame 1 moves downward.
Operation principle of the present utility model is：During wiring, as long as being intended to the wire insertion wire frame 1 and tension disc 2 of connection
Between, then, cam lever 4 is rotated using lever spanner 403 so that wire frame 1 is up raised, and compresses wire, and
Cam lever 4 is pinned；Because the line-ball tongue on tension disc 2 is in the inside of wire frame 1, and tension disc 2 can lead to
Cross top and do small range rotation；Therefore, after external wire is compacted, if firmly pullling wire outward, now, wire and pressure
The rotation of a low-angle can be formed between line plate 2 and wire frame 1, so, wire is instead drawn tighter.
The utility model is simultaneously not limited to the embodiments described above limitation, other any real without departing from spirit of the present utility model
Matter with made under principle change, modification, replacement, combine, simplification, should be equivalent substitute mode, be included in this practicality
Within new protection domain.
