Abstract
The utility model provides a kind of clamping force limitation type clamp, and it comprises jaw, the edge of a knife, limiter handle, assist handle; Described limiter handle, assist handle are symmetrical structure, and be connected as a single entity respectively by jointed shaft and jaw and the edge of a knife, described limiter handle comprises medial surface hinged handle tail, button; Described handle tail, button contact surface are respectively fitted with the relative magnetic patch of opposite pole, the contact surface of the two tension is also connected by spring by described handle tail, button.This clamp is similar with common clamp structure, use palm grip, when grip as carpopodium tail is subject to is excessive, described handle tail will rotate along described articulated position and button, the contact surface that is adjacent to of the two is separated, stressed excessive when so just can prevent this clamp from working, jaw or the edge of a knife are damaged.
Description
Art
The utility model belongs to hardware & tools technical field, especially relates to a kind of clamping force limitation type clamp.
Background technology
Pliers, be a kind of for clamping, fixing processing work or torsion, bend, cut off the hand tools of tinsel.The profile of pliers is V-shaped, generally includes handle, the pincers cheek and jaw three parts.Pliers utilizes lever principle can apply much larger than the clamping force of palm grip object in use.Like this can so that people implement to carry out various operation to clamp object, but in the productive life of reality, many objects or part can not use larger clamping force to carry out clamp, otherwise easily object is pressed from both sides bad, in addition when using the edge of a knife of pliers to cut off operation to tinsel, the intensity wiry that the edge of a knife that different materials is corresponding can be sheared is also different.If the wire be sheared is really up to the mark and carry out easily damaging the shearing edge of a knife of pliers when pinch off operates by force.
Utility model content
For above-mentioned problem, it is simple that the purpose of this utility model is to provide a kind of structure, palm grip on handle can be prevented excessive, to the clamping force limitation type clamp that jaw or the edge of a knife damage when carrying out clamp to part or shearing.
The utility model solves the technical scheme that its technical problem adopts: this clamping force limitation type clamp comprises jaw, the edge of a knife, limiter handle, assist handle; Described limiter handle, assist handle are symmetrical structure, and be connected as a single entity respectively by jointed shaft and jaw and the edge of a knife, described limiter handle comprises medial surface hinged handle tail, button; Described handle tail, button contact surface are respectively fitted with the relative magnetic patch of opposite pole, the contact surface of the two tension is also connected by spring by described handle tail, button.
As preferably, the lateral surface of described handle tail, button is also connected by connecting rod, and the two ends of described connecting rod are processed with the plug inserting handle tail, button respectively.
As preferably, described handle tail, limiter handle inner are processed with the straight hole groove from afterbody perforate respectively.
As preferably, described handle tail, assist handle overlap respectively and has Anti-slip cover.
As preferably, detachably assemble respectively between described magnetic patch and handle tail, button.
The beneficial effects of the utility model are: this clamping force limitation type clamp is similar with common clamp structure, use palm grip, in this clamp, handle tail and button two magnetic patch attract each other, and the tension of spring, make handle tail, button rely on magnetic force and elastic force as a whole, but when using limiter handle, when the common de-clamping of assist handle or shearing part, when grip as carpopodium tail is subject to is greater than the magnetic force and elastic force sum that magnetic patch and spring provide, described handle tail will rotate along described articulated position and button, the contact surface that is adjacent to of the two is separated, stressed excessive when so just can prevent this clamp from working, jaw or the edge of a knife are damaged, this clamp structure is similar to traditional clamp structure simultaneously, conveniently carry out design improvement.
Accompanying drawing explanation
Fig. 1 is the structural representation of clamping force limitation type clamp.
Fig. 2 be clamping force limitation type clamp gripping objects stressed excessive time structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in the embodiment shown in fig, this clamping force limitation type clamp, it comprises jaw 1, the edge of a knife 2, limiter handle 3, assist handle 4; Described limiter handle 3, assist handle 4 are symmetrical structure, and be connected as a single entity respectively by jointed shaft and jaw 1 and the edge of a knife 2, described limiter handle 3 comprises the hinged handle tail 31 of medial surface, button 32; Described handle tail 31, button 32 contact surface are respectively fitted with the relative magnetic patch of opposite pole 33, and the contact surface of the two tension is also connected by spring 34 by described handle tail 31, button 32.
This clamping force limitation type clamp is similar with common clamp structure, occupation mode is identical, use palm grip, in this clamp, handle tail 31 and interior two magnetic patch 33 of button 32 attract each other, and the tension of spring 34, make handle tail 31, button 32 rely on magnetic force and elastic force as a whole, but when using limiter handle 3, when the common de-clamping of assist handle 4 or shearing part, when grip as carpopodium tail 31 is subject to is greater than the magnetic force and elastic force sum that magnetic patch and spring 34 provide, described handle tail 31 will rotate along described articulated position and button 32, as shown in Figure 2, the contact surface that is adjacent to of the two is separated, stressed excessive when so just can prevent this clamp from working, jaw or the edge of a knife 2 are damaged, this clamp structure is similar to traditional clamp structure simultaneously, only there is limiter handle 3 part-structure different, describedly conveniently carry out design improvement.
As depicted in figs. 1 and 2, the lateral surface of described handle tail 31, button 32 is also connected by connecting rod 5, and the two ends of described connecting rod 5 are processed with the plug inserting handle tail 31, button 32 respectively.Described handle tail 31, button 32 can be fixedly connected with by described connecting rod 5, and it does not have limiter function to make this clamp.
As depicted in figs. 1 and 2, described handle tail 31, limiter handle 3 inside are processed with the straight hole groove 6 from afterbody perforate respectively.Described straight hole groove 6 can be used for connecting iron or other break tool of changing a job, lengthened by bar handle, make this clamp have larger clamping force, simultaneously described straight hole groove 6 makes handle tail 31, limiter handle 3 weight lighter.
On described handle tail 31, assist handle 4, cover has Anti-slip cover respectively.Anti-slip cover can be used for skidding when preventing palm grip clamp handle.
Detachably assemble respectively between described magnetic patch 33 and handle tail 31, button 32.
The foregoing is only preferred mode of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
