Abstract

The invention relates to ratchet wheel type bolt clippers. The ratchet wheel type bolt clippers comprise an upper clipper head, a lower clipper head, an upper handle and a lower handle, wherein the upper clipper head and the lower clipper head are movably connected together through two clamping plates and bolts; the front end of the upper handle is an upper fan-shaped portion, an upper arc groove is formed in the upper fan-shaped portion, and an upper ratchet wheel is arranged on the side of the upper fan-shaped portion; the front end of the lower handle is a lower fan-shaped portion, a lower arc groove is formed in the lower fan-shaped portion, and a lower ratchet wheel is arranged on the side of the lower fan-shaped portion; the rear end of the upper clipper head is connected with the upper handle through an upper screw, and the upper screw is formed in the lower arc groove; the rear end of the lower clipper head is connected with the lower handle through a lower screw, and the lower screw is arranged in the upper arc groove; the upper ratchet wheel is engaged with the lower ratchet wheel. The mutually engaged ratchet wheels are adopted, the two handles can be guided by teeth of the ratchet wheels during shearing, and the opening degree between the handles is large, so that more labor is saved, and higher shearing force is provided.

Description

A kind of ratchet-type bolt clipper

Technical field

The present invention relates to the technical field of hardware & tools, refer to a kind of bolt clipper especially.

Background technology

The bolt clipper used at present adopts the mode of link rod to realize the connection between binding clip and handle usually, and by the lever principle of link rod, reaches larger shearing force, realize labour-saving and cut off cable.But be directly proportional between the angle can opened between the length of the shearing force that the bolt clipper of linkage type can reach and handle and handle, when actual production, the length of handle and the angle that can open all limited, also just limit the shearing force of bolt clipper.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of ratchet-type bolt clipper that can provide larger shearing force.

For solving the problem, the technical solution used in the present invention is: a kind of ratchet-type bolt clipper, comprise upper grip head, lower pliers head, upper handle and lower handle, upper grip head and lower pliers head are movably connected by two clamping plate and bolt, the front end of described upper handle is upper scallop, deep-slotted chip breaker is provided with in upper scallop, the sidepiece of upper scallop is provided with ratchet, the front end of described lower handle is lower scallop, arc lower groove is provided with in lower scallop, the sidepiece of lower scallop is provided with bottom ratchet wheel, the rear end of upper grip head is connected with upper handle by screwing, and screwing is arranged in arc lower groove, the rear end of lower pliers head is connected with lower handle by lower screw, and lower screw is arranged in deep-slotted chip breaker, upper ratchet and bottom ratchet wheel are meshed.

Preferably, the tooth of described upper ratchet and bottom ratchet wheel is arc-shaped gear.

Preferably, opening is provided with in described upper scallop and lower scallop.

The invention has the beneficial effects as follows: above-mentioned ratchet-type bolt clipper, it adopts intermeshing ratchet, the guiding between the tooth enabling two handles obtain ratchet when shearing, and the angle can opened between handle is larger, thus more laborsaving, namely provide larger shearing force.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of upper scallop in Fig. 1;

Fig. 3 is the structural representation of lower scallop in Fig. 1;

Detailed description of the invention

Below by specific embodiment, a kind of ratchet-type bolt clipper of the present invention is described in further detail.

As shown in Figure 1, a kind of ratchet-type bolt clipper, comprise upper grip head 1, lower pliers head 2, upper handle 3 and lower handle 4, upper grip head 1 and lower pliers head 2 are movably connected by two clamping plate 5 and bolt 6, as shown in Figure 2, the front end of described upper handle 3 is upper scallop 7, deep-slotted chip breaker 8 is provided with in upper scallop 7, the sidepiece of upper scallop 7 is provided with ratchet 9, as shown in Figure 3, the front end of described lower handle 4 is lower scallop 10, arc lower groove 11 is provided with in lower scallop 10, the sidepiece of lower scallop 10 is provided with bottom ratchet wheel 12, the rear end of upper grip head 1 is connected with upper handle 3 by screwing 13, and screwing 13 is arranged in arc lower groove 11, the rear end of lower pliers head 2 is connected with lower handle 4 by lower screw 14, and lower screw 14 is arranged in deep-slotted chip breaker 8, upper ratchet 9 and bottom ratchet wheel 12 are meshed.

Preferably, the tooth of described upper ratchet 9 and bottom ratchet wheel 12 is arc-shaped gear.Arc-shaped gear can make to be more prone between ratchet 9 and bottom ratchet wheel 12 coordinate and reach engagement.

Preferably, opening 15 is provided with in described upper scallop 7 and lower scallop 10.This opening 15 plays the effect of the peep hole observing ratchet engagement situation, and can play the effect of the weight of saving material and alleviating bolt clipper.

Operation principle of the present invention is: during use, both hands grip upper handle 3 and lower handle 4 respectively, upper handle 3 and lower handle 4 is firmly made outwards to open, now screwing 13 inwardly slides in arc lower groove 11, lower screw 14 inwardly slides in upper deep-slotted chip breaker 8, and upper ratchet 9 and bottom ratchet wheel 12 relatively rotate, along with screwing 13 is drawn close with lower the relative of screw 14, the front end of upper grip head 1 and lower pliers head 2 is opened, because the stroke of upper deep-slotted chip breaker 8 and arc lower groove 11 is longer, make can open larger angle between upper handle 3 and lower handle 4, then the cable of required shearing is placed on after between upper grip head 1 and lower pliers head 2, firmly inwardly close up upper handle 3 and lower handle 4, screwing 13 outwards slides in arc lower groove 11, lower screw 14 outwards slides in upper deep-slotted chip breaker 8, upper ratchet 9 and bottom ratchet wheel 12 relatively rotate, and by the engagement of ratchet, play the guide effect of an arc, make handle more laborsaving when closing up, provide larger shearing force.

The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
