Abstract

The utility model relates to multi-purpose press-cutting pliers which is composed of a cutting part and a handle part, wherein the cutting part is pivoted into a shear shape by two symmetrical blades which are crossed and overlapped with each other. The cutting part is provided with a bent cutting edge, a circular cutting edge and a flat cutting edge; a ratchet wheel and a brake block capable of being engaged with the ratchet wheel are arranged in a right handle of the handle part, the handle can be carried out with idle rotation by a rotating sleeve barrel through a connecting rod to enlarge or reduce an angle, therefore the utility model adapts to the requirement of the force application when thick or thin workpieces are cut off. Compared with the existing cable pliers, the utility model has the characteristics of more functions. The circular cutting edge is used for peeling conducting wires, the flat cutting edge is used for cutting off rivets and screws, and the bent cutting edge is used for cutting off cables.

Description

Multipurpose breaks pincers

A kind of multipurpose breaks pincers, and it relates to the hand-held tool wire nipper of daily use.

The present existing stronger cable wire pincers of rigidity that are used for cutting off, generally all design is made the scissors form as shown in Figure 1.Its front end is the blade 11 of symmetry, and the rear end is two long handles 12 of symmetry, can make backward rotation by pivot 13.With cutting off work through heat treated blade.In order to reach laborsaving its shank is made longer handle, when shearing the big workpiece of diameter, just blade portion must open than wide-angle and can carry out, long except that handle than the heaviness, and cause operation to be difficult for the application of force.When shearing than fine workmanship's part, clamp angle too small, also cause operation inconvenience, the application of force can not get laborsaving state.And cable wire pincers function singleness is not suitable for replacing other instruments to use.

The purpose of this utility model be propose a kind ofly to cut off, cable wire, rivet screw and be used for the electric wire peeling, have three edge of a knife forms of multiple function, and its angle of handle idle running during operation.It is big or hour to have avoided cutting off external diameter, uses the defective that effort can not be in preferable states.

The utility model realizes that in the following way it is made up of blade and shank: blade intersects symmetrically by two takes the blade of putting, and articulates with axle to become to cut the shape body.Front end is the sickleshaped edge of a knife, the centre is the dise knife mouth, the rear end is the flat edge of a knife, about two blade rear ends fix a handle respectively, and on right handle, articulate the abaculus of being with ratchet wheel body with minor axis, its rear end with pivot articulate one up and down respectively with a double wedge can with the brake block of ratchet wheel block engagement, the brake block bottom articulates a connecting rod, be shaped on the stop ring sheet on the connecting rod, be installed with stage clip on the connecting rod, the stage clip other end is blocked in the L shaped stop block front end that passes connecting rod on the sleeve, and the pin key on the connecting rod tail end interts in the inclined hole on sleeve.

The advantage that this utility model has is:

1, function is many, and the tulwar mouth of its front end can be sheared cable wire, steel wire, and the middle circle edge of a knife can be used for the lead peeling, and the flat edge of a knife partly can be used to cut off rivet or screw uses

Can utilize the engagement of ratchet and brake block when 2, it cuts off the work application of force, make angle of handle idle running, make the work of cutting off be in application of force optimum state, adapt to cut off slightly or and be convenient to application of force state than fine workmanship's part.

In conjunction with the accompanying drawings the utility model multipurpose being broken pincers below by embodiment is described in further detail: in accompanying drawing 2, it is made up of blade 20 and shank 30, blade by about two profile symmetries intersect mutually, take and put, articulate with spools 23 and become to cut the shape body.Its front end is the sickleshaped edge of a knife, 211,221, the centre is a circular knife edge 212,222, the back be the flat edge of a knife 213,223 about two blades, its rear end fix a handle respectively, two bolts of wherein left handle 31 usefulness 224,225 are fixing, right handle 32 usefulness minor axises 214,215 are embedded on the stops with axle 34 pivot joint ratchet wheel bodies 33, its rear end with pivot 321 articulate tops, a front side upper and lower have double wedge 351,352 can with the brake block 35 of ratchet wheel block 33 profiles of tooth engagement, brake block lower end and connecting rod 36 pivot joints.Adorn a stop ring sheet 362 on the rod rear end external diameter, stage clip of serial connection before the stop ring sheet, adorn a stop ring sheet 362 on the rod rear end external diameter, stage clip 361 of serial connection behind the stop ring sheet, the stage clip other end is stuck in by before the L shaped stop block 322 that passes in the handle on handle sleeve 37.The connecting rod tail end is equipped with a pin key 371, and it interts in the inclined hole 323 on right handle upper bush 37.Be with plastic wrapper 38 on sleeve 37 external diameters.Their operation principle is referring to accompanying drawing 4 and accompanying drawing 5, in accompanying drawing 4, when desiring holding workpiece and open the edge of a knife 211,221, plastic wrapper 38 on the right handle 32 is clockwise rotated, pin key 371 is tiltedly gone up along inclined hole 323 and is moved, connecting rod 36 moves forward, and brake block 35 is rotated counterclockwise, tooth 352 and ratchet 33 engagements.But the edge of a knife keeps original position, and angle of the inside idle running of handle, can reduce operation opens angle of handle, and it adapts to diameter of work situation work greatly.In accompanying drawing 5, when desiring to cut off workpiece, make pin key 371 do tiltedly to move down the 38 inhour rotations of handle overcoat after the holding workpiece along inclined hole, connecting rod 36 moves backward brake block 35 is clockwise rotated, tooth 351 makes outwards angle of idle running of handle with ratchet 33 engagements, and cutting edge 211,221 keeps original positions can strengthen handle opening an angle, its adapt to shear diameter less or when having cut to low-angle the easy application of force use.
