CN2231151Y - Force aid forceps for cutting wire - Google Patents

Abstract

The utility model relates to a pair of force aid forceps for cutting wires, and providing a novel manual tool for cutting wires for the wiring construction of electric power and post departments. A fixed forceps head (9) is hinged with a rotary forceps head (1) via a pin shaft (10), and the rotary forceps head can rotate around the pin shaft clockwise in order to open a jaw opening to place metallic wires or shear the metallic wires. In addition, the external teeth (A) of the rotary forceps head are provided with push ratchet pawls (6) and brake ratchet pawls (4) engaged with the external teeth (A), and the movement of the push ratchet pawls adopts eccentric structure. Therefore, the rotary forceps head (1) can move clockwise and flexibly with labor saving. The force aid forceps for cutting wires having flexible operation and labor saving can be used for shearing steel-cored aluminium wires with the section of hundreds of square millimeters.

Description

The reinforcement bolt clipper

The utility model relates to a kind of hand tools, particularly a kind of metal wire rod cutting implement.

Metal wire rod is sheared, and the most general instrument of present domestic usefulness still be that lever intersects scissors, uses shortcoming to be: weight is big, the gas of requiring great effort, efficient are low.Also have the hydraulic pressure bolt clipper in addition, easily produce oil leakage phenomenon in the use.Chinese patent application number is that 87204777 " the dual-purpose mechanical pressing plierses " introduced also can be sheared metal wire rods such as cable, and advantage is more, but the jaw stroke is little, the uncomfortable big footpath wire rod of shearing.

The purpose of this utility model is the reinforcement bolt clipper that provide a kind of simple in structure, easy to use, laborsaving, the scope of application is big.

The technical solution of the utility model such as Fig. 1, shown in Figure 2, it is by integral cast handle (8), rotate handgrip (7), rotate binding clip (1), fixed pliers head (9), bearing pin (10), eccentric shaft (5), promote ratchet (6), braking ratchet (4), blade (2), (3), left and right sides clamping plate (11), (12) composition such as, its structure is: fixed pliers head (9) and rotation binding clip (1) are hinged with bearing pin (10), fixed pliers head (9) with rotate binding clip (1) mutually in the jaw of interlock, blade (2) is housed respectively, (3), fixed pliers head (9) bottom is fixed with integral cast handle (8), also insert in the slotted eye of opening on right clamping plate (12) top (C) fixed pliers head (9) bottom, connect by eccentric shaft (5), the other end of eccentric shaft, be equipped with and promote ratchet (6), ratchet and external tooth (A) engagement of rotating binding clip (1), rotate on the external tooth (A) of binding clip (1), the braking ratchet (4) that is meshed with it also is housed, in case the moving binding clip counter-rotating of spline.The bearing pin of braking ratchet (4) is to be fixed on the fixed pliers head (9).Eccentric shaft (5) is to be fixed between left and right clamping plate, and right clamping plate bottom is fixed with rotates handgrip (7).

Rotate binding clip (1) external tooth (A) and can be sector.

Rotating binding clip (1) can turn round around bearing pin (10).

The cutting edge of blade (2), (3) can be recessed half garden arc (B).

Operation principle: the moving handgrip (7) that rotates of plate is around eccentric shaft (5) reciprocally swinging, under eccentric shaft drives, make the promotion ratchet (6) that is contained on the eccentric shaft constantly promote to rotate binding clip (1) sector (A) successively, the rotation binding clip is turned clockwise around bearing pin (10), thereby make the jaw of rotation binding clip and the jaw of fixed pliers head respect approaching, interlock mutually, the metal wire that places between the jaw blade is cut off, finishes shearing work.Continue the moving handgrip reciprocally swinging that rotates of plate, ratchet (6) promotes to rotate binding clip (1) to be continued to turn clockwise around bearing pin (19), and two jaws can be opened fully, at this moment, can pack into by the trimming material in fixed pliers head (9) jaw, begin shear history next time.

The utility model provides a kind of desirable manual cutting implement for construction, the repairing of electric power and postal and telecommunication entities, this instrument, and the scope of application is big, can cut the steel core aluminium hinge line in hundreds of square millimeter cross section, and is flexible to operation laborsaving.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is A-A cut-away view of Fig. 1.

Embodiment: fixed pliers head (9) and rotation binding clip (1) are hinged with bearing pin (10), rotating binding clip (1) can turn round around bearing pin (10), fixed pliers head (9) with rotate binding clip (1) mutually in the jaw of interlock, it is the blade (2) of half garden arc (B) that cutting edge is housed respectively, (3), fixed pliers head (9) bottom is installing integral cast handle (8), also insert in the slotted eye of opening on right clamping plate (12) top (C) bottom of fixed pliers head (9), connect by eccentric shaft (5), the other end of eccentric shaft, adorning promotion ratchet (6), ratchet is meshed with the external tooth (A) that rotates binding clip (1), can promote to rotate binding clip (1) rotates around bearing pin (10), for preventing to rotate the binding clip counter-rotating, also be provided with braking ratchet (4), the bearing pin of braking ratchet is fixed on the fixed pliers head (9), and eccentric shaft (5) is to be fixed on a left side, right clamping plate (11), (12) between, in right clamping plate bottom, also be fixed with and rotate handgrip (7).
