Description
Technical field
This utility model relates to the ratchet screwdriver of a kind of band activity boost bar.
Background technology
Screwdriver is a kind of conventional instrument, is used for twisting screw so that it tightens or loosens.Generally there is a thin sphenocephaly, can be inserted in the line of rabbet joint or the recess of screw cap, by rotation screw cutter and then drive screw, to reach to tighten and unclamp the purpose of screw.
Normal screws cutter in use, selects the cutter head corresponding with screw head line of rabbet joint shape, the strength pressing screwdriver shank of user hand so that driver bit and the screw line of rabbet joint coordinate.User rotation screw shank section simultaneously so that screwdriver drives screw clockwise or rotates counterclockwise.
If operating inappropriate when of using screwdriver, as not enough in pressed the strength of screwdriver handle when twisting, it is possible to produce the phenomenon skidded, the line of rabbet joint of screw is damaged, the screw that the line of rabbet joint damages is difficult to continuation screwdriver and twists, and especially causes adverse influence when screw to be unclamped.
Utility model content
In view of the deficiencies in the prior art, technical problem to be solved in the utility model is to provide the ratchet screwdriver of a kind of band activity boost bar, and not only structure design is simple, reasonable, but also can avoid skidding, the most convenient.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: the ratchet screwdriver of a kind of band activity boost bar, including click structure and through the joining knife bar of thrust ball bearing and handle of a knife, described click structure comprises the ratchet being set in outside knife bar and being fixedly connected with knife bar, it is arranged with rotating cylinder outside described ratchet, described ratchet is connected through left pawl, right ratchet and driving lever with rotating cylinder, is hinged with rotating boost bar outside described rotating cylinder.
Preferably, described left pawl is connected with right ratchet through driving lever, is additionally provided with back-moving spring between described left pawl and right ratchet, is also arranged with gland joining with rotating cylinder outside described knife bar, and described driving lever is hinged with gland.
Preferably, described boost bar is u-shaped.
Preferably, it is additionally provided with pressure ring between described knife bar and handle of a knife.
Compared with prior art, this utility model has the advantages that the design of this utility model structure is simple, rationally, can one direction work clockwise or counterclockwise, it is applicable to big torsion duty, can also work with twocouese counterclockwise clockwise, it is adaptable to little torsion duty, the suitability is good, and boost bar cooperates with thrust ball bearing, it is prevented effectively from skidding.
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.

In figure: 1-click structure, 11-ratchet, 12-rotating cylinder, 13-left pawl, the right ratchet of 14-, 15-driving lever, 16-back-moving spring, 17-gland, 2-thrust ball bearing, 3-knife bar, 4-handle of a knife, 5-boost bar, 6-pressure ring.
Detailed description of the invention
For features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing, it is described in detail below.
As shown in Fig. 1 ~ 4, a kind of ratchet screwdriver of band activity boost bar, including click structure 1 and through the joining knife bar of thrust ball bearing 23 and handle of a knife 4, described click structure 1 comprises the ratchet 11 being set in outside knife bar 3 and being fixedly connected with knife bar 3, it is arranged with rotating cylinder 12 outside described ratchet 11, described ratchet 11 is connected through left pawl 13, right ratchet 14 and driving lever 15 with rotating cylinder 12, is hinged with rotating boost bar 5 outside described rotating cylinder 12.
In this utility model embodiment, described left pawl 13 is connected with right ratchet 14 through driving lever 15, being additionally provided with back-moving spring 16 between described left pawl 13 and right ratchet 14, described knife bar 3 is outer is also arranged with gland 17 joining with rotating cylinder 12, and described driving lever 15 is hinged with gland 17.
In this utility model embodiment, described boost bar 5 is u-shaped.
In this utility model embodiment, between described knife bar 3 and handle of a knife 4, it is additionally provided with pressure ring 6.
nullSpecifically used process of the present utility model is as follows: described boost bar 5 is rotated expansion，Rotate described driving lever 15，Described left pawl 13 is meshed with ratchet 11，The clockwise direction of described boost bar 5 is operative orientation，The counter clockwise direction of described boost bar 5 is idle running direction，Opposite direction rotates described driving lever 15，Described right ratchet 14 is meshed with ratchet 11，The counter clockwise direction of described boost bar 5 is idle running direction，The clockwise direction of described boost bar 5 is idle running direction，Thus realize described boost bar 5 one direction and rotate，Now a hands of user rotates described boost bar 5，Described knife bar 3 one direction is driven to twist screw，Another hands presses described handle，Pressure is passed to knife bar 3 by thrust ball bearing 2 by described handle，Ensure there is enough pressure between described knife bar 3 and screw，Reduce the probability skidded，Increase moment of torsion，Improve the efficiency twisting screw；Rotating described driving lever 15 to middle position, the most described left pawl 13 is all meshed with ratchet 11 with right ratchet 14, the most described boost bar 5 locking, cannot rotate, directly described boost bar 5 is rotated and close, similar to normal screws cutter, it is adaptable to use in the case of little torsion.
This utility model is not limited to above-mentioned preferred forms, and anyone can draw the ratchet screwdriver of other various forms of band activity boost bars under enlightenment of the present utility model.All impartial changes done according to this utility model claim and modification, all should belong to covering scope of the present utility model.
