Problems solved by technology

Due to the above structure, although the joint arm has a certain leverage and can achieve the function of saving labor, the shearing force that the bolt cutter can achieve is proportional to the length of the handle.
In actual production, if the length of the handle is too long, it will be inconvenient to carry and store

Embodiment Construction

[0013] The folding bolt cutter of the present invention will be further described in detail through specific embodiments below.

[0014] Such as figure 1 , figure 2 As shown, the folding bolt cutter is composed of a cutter head 1, a joint arm and a handle 2. The cutter head 1 and the joint arm are connected to each other by screws, the handle 2 is arranged at the end of the joint arm, and the two splints 3 are connected by bolts. The cutter head 1 is movably connected together, and the two connecting arms are also connected to each other by screws. The connecting arms include a front connecting arm 4 and a rear connecting arm 5. The rear connecting arm 5 is hinged on the front connecting arm 4, and a useful Used to lock or unlock the locking part of the rear link arm 5.

[0015] As a preferred solution, the rear end of the front connecting arm 4 is provided with a front connecting block 6, the front connecting block 6 is provided with a front through hole 7, and the front e...

Abstract

The invention relates to foldable bolt clippers. The foldable bolt clippers are composed of cutter heads, linkage arms and handles, wherein the cutter heads are connected with the linkage handles through screws; the handles are arranged at the ends of the linkage arms; the two cutter heads are movably connected together by two clamping plates through bolts; the two linkage arms are connected through screws and include the front linkage arm and the rear linkage arm, and the rear linkage arm is hinged to the front linkage arm; a locking part used for locking or opening the rear linkage arm is arranged in the hinge position. The linkage arms are foldable, so that the length of the foldable bolt clippers is reduced when the foldable bolt clippers are not used, and then the foldable bolt clippers are more convenient to carry and store.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a bolt cutter. Background technique [0002] The bolt cutter is mainly composed of a cutter head, a link arm and a handle. The cutter head and the link arm are connected to each other by screws, and the handle is set at the end of the link arm. The two arms are also connected to each other by screws. Its working principle is: when you need to cut an object, open the two handles and the joint arms, and the two cutter heads will also open, put the object between the cutting edges of the two cutter heads, and then close it forcefully, and the two cutter heads will be opened. The cutter head is also closed up, until the steel bar is cut off. Due to the above structure, although the connecting arm has a certain leverage and can achieve the function of saving labor, the shearing force that the bolt cutter can achieve is directly proportional to the length of the handle. In ac...
