Description
Technical field
The utility model relates to a kind of five metals apparatus, especially, is a kind of pliers.
Background technology
Common pliers is made up of jaw, pincers plug and handle, according to lever principle, holds handle when cutting out object, jaw is closed, use less power object can be cut off, but when cutting out the larger object of hardness, user possibly easily cannot cut off object; In addition, the spacing between handle is very little, if any accidentally overexerting, can cause the excessive occlusal at jaw place, being damaged by object.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of roller type pliers, and this roller type pliers can cut out the larger object of hardness like a cork, and can effectively prevent because of the firmly excessive damage caused object.
For solving the problem, the technical solution of the utility model is: this roller type pliers comprises jaw, the pincers cheek, handle, and surrounds the housing of described handle; Described handle two-arm end connects a Compress Spring; The through hole that the two-arm of described handle respectively has a row evenly to arrange vertically, between the two-arm of described handle, there is metal wire, described metal wire forms spiral form successively through each described through hole, and described metal wire one end is fixed on handle, and the other end is connected to one with on the wire spool of winding slot; Described wire spool is connected on the housing by wire coil shaft, and freely can rotate around described wire coil shaft; There is ratchet wire spool periphery, and the ratchet on described ratchet and described housing matches; Described ratchet can turn connection on the housing by pawl axis; Have the window that can be exposed wire spool on the housing.
The beneficial effects of the utility model are: when using this roller type pliers, object is put into jaw, wire spool is rotated at the window place that described housing is outputed, wire spool is wound around and strains metal wire, the metal wire be wrapped in handle two-arm shortens, handle is closed up, due to handle two-arm between the less distance of relative displacement, each circle of the helical of the formation of described metal wire all will shorten corresponding distance, therefore, whole piece metal wire will produce larger displacement, and wire spool will turn over larger angle, therefore, according to conservation of mechanical energy principle, as long as apply less revolving force to wire spool, jaw can be made to produce very large snap-in force, after finger unclamps, the ratchet on housing blocks the ratchet of wire spool, and now wire spool can not reverse, and jaw is still in interlocking pattern, after use terminates, mentioned by ratchet, handle separately, around the wire drawing on handle, drives wire spool reversing, realizes the reset of pliers under the promotion of spring.This roller type pliers applies less revolving force to wire spool can produce very large snap-in force at jaw place, easy to use; When slowly rotating wire spool, can finely tune jaw, effectively preventing because of the firmly excessive damage to object.
This roller type pliers is simple to operate, easily can cut off the larger object of hardness, can realize accurate operation simultaneously, and fine setting wire spool can allow jaw slowly be engaged, and not easily causes object to damage.
As preferably, the number of turn of the helical that described metal wire is formed is 4-6 circle, so that quick adjustment, uses less power can realize jaw occlusion simultaneously.
As preferably, described pawl axis interior arrangement has a clockwork spring be connected with ratchet, prevents pliers to be inverted ratchet when using and leaves from ratchet, effectively prevent the reversing of wire spool.
As preferably, the edge of described through hole is rounding shape, can effectively reduce frictional force when metal wire slides in through hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the sectional view of ratchet and pawl axis in an embodiment of the present utility model.
Detailed description of the invention:
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, this roller type pliers comprises jaw 1, the pincers cheek 2, handle 3, and surrounds the housing 4 of described handle; Described handle 3 two-arm end connects a Compress Spring 5; The two ends of spring 5 are connected in the two-arm of handle 3; The through hole 31 that the two-arm of described handle 3 respectively has a row evenly to arrange vertically, between the two-arm of described handle 3, there is metal wire 8, described metal wire 8 forms spiral form successively through each described through hole 31, the edge of described through hole 31 is rounding shape, wire coil is wound around 5 circles on the handle 3, and described rounding shape can effectively reduce the frictional force that metal wire 8 slides at through hole 31 place; Described metal wire 8 one end is fixing on the handle 3, and the other end is connected to one with on the wire spool 6 of winding slot 61; Described wire spool 6 is connected on described housing 4 by wire coil shaft 60, and freely can rotate around described wire coil shaft 60; There is ratchet 62 wire spool 6 periphery, and described ratchet 62 matches with the ratchet 7 on described housing 4, and ratchet 7 can stop wire spool 6 to rotate counterclockwise; Described ratchet 7 can be turned by pawl axis 71 and is connected on housing 4; In the sectional view of the ratchet shown in Fig. 2 and pawl axis, described pawl axis 71 interior arrangement has a clockwork spring 9 be connected with ratchet 7, and after ratchet 7 is raised, clockwork spring 9 pushes back by ratchet 7, and wire spool 6 can be made to reverse; Decontrol ratchet 7, clockwork spring 9 turns round, and promotes ratchet 7, is stuck in by ratchet 7 in ratchet 62, stops wire spool reversing; Described housing 4 has the window that can be exposed wire spool 6.
When using this roller type pliers, object is put into jaw 1, the window place outputed at described housing 1 rotates clockwise wire spool 6, now wire spool 6 is wound around and strains metal wire 8, the metal wire 8 be wrapped in handle 3 two-arm shortens, handle 3 is closed up, due to handle 3 two-arm between the less distance of relative displacement, each circle of the helical of the formation of described metal wire 8 all will shorten corresponding distance, therefore, whole piece metal wire 8 will produce larger displacement, and wire spool 6 will turn over larger angle, therefore, according to conservation of mechanical energy principle, as long as apply less revolving force to wire spool 6, jaw 1 can be made to produce very large snap-in force, after finger unclamps, the ratchet 7 on housing 4 blocks the ratchet 62 of wire spool 6, and now wire spool 6 can not reverse, and jaw 1 is still in interlocking pattern, after use terminates, mentioned by ratchet 7, handle 3 separately, elongates around metal wire 8 on the handle 3 under the promotion of spring 5, drives wire spool 6 to reverse, realizes the reset of pliers.This roller type pliers applies less revolving force to wire spool can produce very large snap-in force at jaw 1 place, easy to use, when slowly rotating wire spool 6, can finely tune jaw 1, effectively preventing because of the firmly excessive damage to object.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
