Description

Cable break pincers convenient for collecting

Technical field

The utility model is related to pliers field more particularly to a kind of cable break pincers convenient for collecting.

Background technology

Cable break clamps, and is a kind of tool being used for cutting cable.

Cable break pincers in traditional technology include cutter head, joint arm and handle, and cutter head and joint arm rotation connection, handle are arranged In the one end of joint arm far from cutter head, two cutter heads are movably connected by clamping plate, are rotatablely connected between two joint arms.Its work It is as principle：When needing to shear cable, two handles and joint arm are opened, two cutter heads also and then open, and put object into two It between the cutting edge of cutter head, then firmly closes, two cutter heads also and then close up, until cutting cable.

When shearing cable, joint arm has certain leverage, can reach labour-saving function, by physics knowledge, For lever principle it is found that by the longer of handle setting, the arm of force is longer, and torque output is also bigger, is more saved when shearing cable Power, in actual production, it is impossible to which handle can be generally arranged to the greatest extent may be used by the endless that handle is arranged in proper range Can be longer to play power-saving function, if but handle length it is long, and can to carry or store it is inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of cable break pincers convenient for collecting, to a certain extent, can make Still with power-saving function when must carry and store conveniently, and can make handle with certain length to ensure to shear cable.

The above-mentioned purpose of the utility model technical scheme is that：

A kind of cable break pincers convenient for collecting, including cutter head, the cutter head include knife mouth, the cutter head is far from the knife One end of mouth is connected with joint arm, and the one end of the joint arm far from the cutter head, which is arranged, is hinged with two telescopic handles, and two The handle can correspond overturning to the both sides for being located at the joint arm around the hinge joint rotation of its own；The handle includes more The casing that Duan Yici is socketed layer by layer is provided between each two adjacent casing for being oriented to casing so that casing can only be axial It slides and the guider that can not be circumferentially rotated, anti-drop device and use for preventing inner layer sleeve to be detached from from outer layer sleeve In fixed sleeving so that handle keeps the fixing device of elongation state；One end of the described sleeve pipe of innermost layer is provided with interconnecting piece, It is provided with connecting seat in the joint arm, articulated shaft is provided on the connecting seat, connecting hole is provided on the interconnecting piece, it is described Connecting hole is sheathed on the articulated shaft to realize being hinged for the handle and the joint arm；The interconnecting piece is set on connecting seat It is equipped with for making the handle and the joint arm keep folded state or the limit assembly of unfolded state.

Implement above-mentioned technical proposal, when the cable break convenient for collecting need not be used to clamp, by all inner layer sleeves according to It is secondary to shrink layer by layer until be all contracted in outermost casing so that handle is maintained at contraction state, and by handle around its from Body and the rotation of the hinge joint of joint arm are allowed to overturn to the both sides of joint arm, and by limit assembly handle are always maintained at joint arm Folded state, to reduce occupied spatial volume so that storage is more convenient；When need use the electricity convenient for collecting When cable bolt clipper, first handle is allowed to be unfolded around the hinge joint rotation of its own and joint arm, then all inner layer sleeves are complete It is all pulled out from outermost casing, handle will be fixed device and fix so that handle keeps elongation state, in shearing cable When, the longer arm of force can be provided, to ensure that larger torque is exported to play power-saving function.Therefore, this electricity convenient for collecting Cable bolt clipper can to carry and store convenient and handle is made to have certain length to ensure to shear to a certain extent Still there is power-saving function when cable.

Further, the limit assembly includes the counterbore being arranged on the interconnecting piece, and sliding is provided in the counterbore The thimble that can be slided in the counterbore is connected, is provided between the thimble and the bottom wall of the counterbore so that the thimble one The straight elastic component with the trend far from the counterbore, the one end of the thimble far from the elastic component is provided with bulb, described It is provided on connecting seat and is placed in first shrinkage pool with matched first shrinkage pool of the bulb and the second shrinkage pool, the bulb Then the handle and the joint arm keep folded state, the bulb be placed in second shrinkage pool then the handle with it is described Arm keeps unfolded state, is connected to by arc groove between first shrinkage pool and second shrinkage pool, and first shrinkage pool Depth and the depth of the second shrinkage pool are consistent with the radius of the bulb.

Implement above-mentioned technical proposal, when handle is rotated around hinge joint, thimble will be driven also and then to rotate, in this process In, thimble will slide in arc groove, and when thimble slides at the first shrinkage pool, bulb slides into the first shrinkage pool so that handle Folded state is kept with joint arm；When thimble slides at the second shrinkage pool, bulb slides into the second shrinkage pool so that handle and joint arm Unfolded state is kept, it is simple and reasonable, it is easy to implement.
