Abstract

The utility model relates to a ratchet closed-end spanner. An annular sleeve is arranged in the annular hole of a dentiform spanner, the outer margin of the annular sleeve is provided with four grooves, and the inner margin of the annular sleeve is provided with a clamping angle. A jack and a spring are arranged in each groove. At the time of work, the jack is pushed in and is bounced out of the annular hole, and a spanner with the function of a one way ratchet. A screw cap can be conveniently screwed down or unscrewed on a small positions, and the spanner does not need taking out of the screw cap. The utility model avoids the defect that the existing spanner is repeatedly sheathed in or taken out of the screw cap for screwing the screw cap.

Description

The ratchet-type wrench of remaining silent
A kind of ratchet closed spanners, it belongs to hand-held tool spanner field.
Existing closed-end spanner generally is to make single solid type, and its wrench body one end is an annular termination, is shaped on the work tooth on inner edge, during use it is fastened in moving, the rotation of gusset on hex bolts or the nut, it is screwed or unclamps.But because the influence in space promptly must be taken out by nut after pulling an angle, the original angle of spanner backspace is buckled into again continue to pull rotation more in use, screw or unclamp purpose to reach.So extremely inconvenient in the use, work efficiency is low, particularly when space, nut place was narrower and small, it is more outstanding that this shortcoming seems.
The purpose of this utility model be disclose a kind of in the scallop of spanner termination, but adorn a clip hex nut, ring set, it also is equipped with very heavy and spring, become the intermittent movement ratchet closed spanners during work, needn't can carry out easily that screwing type unclamps by taking out on the nut and being inserted in, the work of bolt or nut.
The utility model is realized in the following way, on the looping pit inner edge of spanner termination, evenly be shaped on profile of tooth, putting on an outer rim in the looping pit has 4 grooves, the retaining wedge angle that grip bolt formula nut is arranged on the inner edge, the ring set that becomes to be rotatably assorted with looping pit.In 4 grooves of ring set, very heavy block and spring are housed respectively.
The advantage that this utility model has is, it can unidirectionally move nut or bolt, it is screwed or unclamp, need take out repeatedly and be inserted in when having avoided the operation of existing closed-end spanner back and forth move just can finish to hex nut or bolt screw or unclamp work it and be designed to improve this tool life by two groups of very heavy block one after the other work.
Description of drawings:
Accompanying drawing 1, the utility model axonometric exploded view
Accompanying drawing 2, the utility model stereogram
Accompanying drawing 3, the utility model front view enlarged drawing
In conjunction with the accompanying drawings a kind of ratchet closed spanners of the utility model is described in further detail below by embodiment: a looping pit 3 is arranged on the termination 2 of spanner handle 1, on the inner edge of looping pit, evenly be shaped on profile of tooth 4, putting one in the looping pit becomes the ring set 5 that is rotatably assorted with the hole, is the angle card angle 9 of mounting board nut or screw diagonal-size on the inner peripheral surface of ring set endoporus.Be shaped on the groove 6 of 4 symmetries on the cylindrical, and groove at 30 ° at two groups of angles of circumference of ring set on line position.Be equipped with one in each groove and press spring 8 with the match very heavy catch 7 of crossed belt rounded triangle and one of its shape, and the very heavy block at one group of diagonal angle is pressed in by spring 8 in the tooth paddy of looping pit in two groups, and another is organized very heavy block and is leaned on crown by the profile of tooth 4 of looping pit just.Move spanner when work when being inserted in nut or bolt, ring set 5 rotates in looping pit 3 and one group of very heavy block 7 is pressed into by spring 8 in the tooth paddy of profile of tooth 4 of looping pit force ring set to rotate with wrench body.Another organizes very heavy block 7 and spring 8 then is pressed in ring set 5 grooves 6 by the crown of profile of tooth 4, and nut or bolt head are rotated.When the spanner reversed turning, because throwing off the very heavy block that makes in the groove 6, ejected profile of tooth 4 crowns, withstanding in the looping pit profile of tooth 4 becomes the single direction ratchet effect, and nut or bolt are unclamped.Again buckle into behind the taking-up spanner handle reverse when screwing and get final product.
