In order to achieve the foregoing creative purpose, the present clip structure includes a first caliper handle, a second caliper handle, a spring and a buckle. The first caliper handle is pivotally disposed with the second caliper handle to form a a first handle, a second handle, a first cutter and a second cutter, the spring is disposed between the first handle and the second handle, and provides a first handle and a second grip The handle and the first cutting pliers and the second cutting pliers maintain a normally open elastic force, and the first pliers is formed with a hook at a position close to the inner surface of the first grip, and the second grip is formed with a hook Providing a slot for the inner side and the outer side; the buckle is pivotally disposed in the installation slot, the buckle has a lever portion extending from the slot, and a positioning portion corresponding to the inner surface of the first handle, the positioning The segment has a protruding rod that is buckled on the hook, and a normal pulling fastener is arranged between the end surface of the buckle and the surface of the second handle, so that the protruding rod is released from the release spring of the hook elastic force. When the lever is placed on the hook, the first handle and the second grip retain a reserved space for avoiding the release of the protruding rod from the hook.

In this way, when the operator uses the creation of the cutting pliers, the position of the thumb corresponds to the position of the lever portion of the buckle, so that the user can push the buckle through the thumb to make the hook and the buckle buckle to achieve the scissors. When the forceps are to be released, only the first handle and the second handle are slightly pressed to shrink the reserved space, so that the protruding rod and the hook are misaligned to obtain a release space for the release. The spring pulls out the bulge to release the positioning effect.

The buckle is formed on the lever section to form an arc curved surface.

It can be seen from the above-mentioned creation that the creation "cutting pliers structure" has a safety fastening device, and the safety fastening device corresponds to the operator's thumb portion, and has a quick and convenient operation mode, and when the operator desires When using the cutting pliers, it is only necessary to press the two grips to quickly release the operation mode for the blade to open; therefore, the novel can be said to be a quite practical and progressive creation, which is worthy of promotion by the industry and is publicized.
