Should go up folder instrument and comprise conducting rod and clamp, wherein, said clamp comprises and comprises the first arm and second arm, and the front end of the said the first arm and second arm is a jaw portion, and the rear end is a handgrip, and said the first arm and second arm are each other with pivotal connection;

Said conducting rod is provided with at least one bayonet slot;

The jaw portion inboard of said clamp has a depressed part, and said depressed part can with the bayonet slot interlock of said conducting rod.

In the utility model, said conducting rod is provided with at least one tip, and the tip of said conducting rod and said bayonet slot are arranged on the both sides of said conducting rod; Preferably, said conducting rod has two bayonet slot and two tips, is arranged on the both sides of said conducting rod respectively symmetrically.

In the utility model, the depressed part of said clamp is a rectangle recess, the bayonet slot of said conducting rod be one with the rectangle recess of the depressed part of said clamp coupling.

In the utility model, the inner surface of the said second arm jaw portion is set to zigzag.

In the utility model, the said the first arm and second arm are each other with the spring pivotal connection.

In the utility model, when the handgrip of the said the first arm and second arm applied grip, said jaw portion opened.

In the utility model, the described folder instrument of going up is used for the fixing of aluminium section bar.

The utility model has following advantage compared with prior art:

1, folder mode on the clamp-type, efficient is high, and cost is low; And can guarantee that section bar is consistent with the tightness of conducting rod, avoid conducting electricity bad, to folder mode on the conventional pliers; The utility model has been developed the conducting rod structure, cooperates clamp specially, the service life that can improve conducting rod;

2, more effective clamping section bar guarantees that section bar contacts with conducting rod well;

3, conducting rod can use on both sides, promptly on conventional conductive bar basis in service life, the service time that doubles, has reduced cost.

Reference numeral:

The specific embodiment

Below will combine accompanying drawing and specific embodiment further to set forth the advantage of the utility model.

See also Fig. 1 and Fig. 2, be the structural representation of the utility model one embodiment.The above folder instrument of the utility model is that example is explained.

The last folder instrument of the utility model comprises conducting rod 10 and clamp 30.The front side of conducting rod 10 is provided with tip 102, is provided with bayonet slot 101 at the rear side of conducting rod 10, wherein; Tip 102 is used to prop up section bar 20 fixedly the time, preferably, bayonet slot 101 is set to a rectangle recess; And this conducting rod 10 is provided with two bayonet slot 101 and two tips 102; The both sides that are symmetricly set on this conducting rod 10 respectively as shown in Figure 1 are so that conducting rod 10 can both sides use, on the conventional conductive bar basis in service life; Service time about doubling, thus can significantly reduce cost.

The clamp 30 of the utility model comprises the first arm 301a and the second arm 302b; And the front end of this first arm 301a and the second arm 301b is jaw portion 303, and its rear end is handgrip 302, wherein; This first arm 301a and the second arm 301b pass through pivotal connection; To realize the rotation in its same Plane of rotation, further, jaw portion 303 inboards of the first arm 301a are provided with a depressed part 304.Preferably; This first arm 301a and the second arm 301b can pass through spring 305 pivotal connections, cross-like and parallel shape setting all can, also can adopt modes such as spring steel ball detent mechanism; Receive the inside elastic force of spring with the two jaw portions 303 that realize; Two jaw portions 303 can't open when not applying external force, have only when handgrip 302 applies enough inside grip, and jaw portion 303 just can outwards open.In addition, the depressed part 304 of jaw portion 303 and the bayonet slot 101 of conducting rod 10 are made as a rectangle recess, but or other can realize clamp 30 and the fixing matched shape of conducting rod 10 interlocks; Jaw portion 303 inboards of the second arm 301b can be made as zigzag, for fixing this section bar 20 more firmly; The handgrip 302 of the first arm 301a and the second arm 301b can be established a recess; This recess can evenly be constructed consistently; For example be set to arc, with the shape increase frictional force of coupling user hand, further; Distance between the handgrip 302 is set to the width of a finger at least, with prevent the user in use clamp 30 clip to finger.
