Preferably, the bite of described conducting rod is multiple buckle steps, and the inner side in the second jaw portion of described second arm is provided with the multiple grooves be engaged mutually with described buckle step.

Preferably, described buckle step is rectangular lug boss, and described groove is rectangular depressed part.

Preferably, the inner surface of described first arm is set to zigzag.

Preferably, the first grip part of described first arm is outward extending arc shape.

After have employed technique scheme, compared with prior art, there is following beneficial effect:

1. by meeting the clamp assemblies of the utility model preferred embodiment, can convenient, efficiently, securely by conducting rod and section bar clamping, conducting rod is contacted with section bar well, keeps section bar consistent with the tightness of conducting rod, there will not be the situation of loose contact.

2. the clamp assemblies of the utility model preferred embodiment has carried out specialized designs to the concrete structure of conducting rod, and coordinates corresponding fixture, drastically increases the holding capability of clamp assemblies, and clamping effect is more remarkable compared with general setting tool.

3. the clamp assemblies of the utility model preferred embodiment only needs to apply grip to the grip part of fixture, just can easily fixture be opened, thus remove the sandwich relationship of conducting rod and section bar, or as required conducting rod and section bar are clamped again, occupation mode is flexible.

4. the clamp assemblies of the utility model preferred embodiment can repeatedly use, and has saved resource, has reduced cost.

Detailed description of the invention

Advantage of the present utility model is set forth further below in conjunction with accompanying drawing and specific embodiment.

The clamp assemblies meeting the utility model preferred embodiment comprises conducting rod 1 and fixture 2, and it is applied on section bar 3, and such as can be applied to cross section is on square aluminium alloy extrusions 3.

As shown in Figure 1, Fig. 1 shows the structure of the conducting rod meeting the utility model preferred embodiment.Specifically, conducting rod 1 comprises main part 11, protuberance 12 and bite 13, and wherein protuberance 12 extends from the side of main part 11 towards the direction vertically away from main part 11, and bite 13 is arranged on the relative opposite side of main part.

As shown in Figure 2, the fixture 2 meeting the utility model preferred embodiment comprises the first arm 21 and the second arm 22, between first arm 21 and the second arm 22 by resilient pivot portion 23 connect make the first arm 21 and the second arm 22 round resilient pivot portion 23 in a plane open and close, first arm 21 comprise the first jaw portion 211 for clamping section 3 being positioned at front end and the first grip part 212, second arm 22 being positioned at rear end comprise be positioned at front end for clamping and being engaged the second jaw portion 221 of the bite 13 of conducting rod 1 and being positioned at the second grip part 222 of rear end.

The operation principle of the clamp assemblies of the utility model preferred embodiment is: the first grip part 212 and the second grip part 222 of pressing fixture 2, first arm 21 and the second arm 22 are outwards opened round resilient pivot portion 23, by the outer surface of the protuberance 12 of conducting rod 1 against some sides (such as side A) of section bar 3, then the first grip part 212 and the second grip part 222 is discharged, the second jaw portion 221 of the second arm 22 is made to be engaged and to clamp the bite 13 of conducting rod 1 by the elastic clamping power of fixture 2, first jaw portion 211 of the first arm 21 clamps the inner surface of side A simultaneously, thus realize by conducting rod 1 and section bar 3 mutually fastening.

By adopting the clamp assemblies of the utility model preferred embodiment, can convenient, efficiently, firmly conducting rod 1 and section bar 3 are clamped, conducting rod 1 is contacted with section bar 3 well, keeps section bar 1 consistent with the tightness of conducting rod 3, there will not be the situation of loose contact; Only need to apply grip to the first grip part 212 of fixture 4 and the second grip part 222, just can easily fixture 4 be opened, thus remove the sandwich relationship of conducting rod 1 and section bar 3, or as required conducting rod 1 and section bar 3 are gripped again, occupation mode is flexible; Repeatedly can also use, save resource, reduced cost.

Preferably, as shown in Figure 1, the bite 13 of conducting rod 1 is multiple buckle steps, and as shown in Figure 2, the inner side in the second jaw portion 221 of the second arm 22 is provided with the multiple grooves be engaged mutually with buckle step.Further, this buckle step is rectangular lug boss, and groove is rectangular depressed part.Certainly, other also can be adopted conducting rod 1 and fixture 2 can be realized to be engaged the shape of fixing mutual coupling.The clamp assemblies of the utility model preferred embodiment has carried out specialized designs to the concrete structure of conducting rod 1, and coordinates corresponding fixture 2, and drastically increase the holding capability of clamp assemblies, clamping effect is more remarkable compared with general setting tool.

Preferably, the inner surface of described first arm is set to zigzag, thus can more firmly fix section bar 3.

Preferably, the first grip part of described first arm is outward extending arc shape, thus the hand-type of coupling user increases frictional force, and what it is such that fixture 2 can be convenient opens, and makes the use hommization more of fixture 2.

Should be noted that, embodiment of the present utility model has preferably implementation, and not any type of restriction is done to the utility model, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solutions of the utility model is not departed from, the any amendment done above embodiment according to technical spirit of the present utility model or equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
