Description

Ratchet operated screwdriver

The utility model relates to a kind of ratchet-type screwdriver.

A kind of ratchet screw is arranged in the prior art, in its handle, rotary body is housed, and symmetrical stops and spring, stops can match with rotary body, for making ratchet screw can reach to the left or to the right unidirectional rotation, the corresponding setting can be controlled the complex appts that rotary body rotates in handle and end cap, this not only make ratchet screw manufacturing, relatively difficulty is installed, and increased the cost expenditure.

The utility model is to improve on the basis of existing technology to form, and its purpose is to provide a kind of making, easy for installation, cheap ratchet-type screwdriver.

The purpose of this utility model is achieved in that it is mainly by handle, cutter hub and end cap are formed, in the groove of handle, rotary body is housed, symmetrical stops and spring are housed in the handle straight trough, rotary body matches with stops, positioning bead is housed on handle, positioning bead can be respectively matches with three little concave points on the end cap, it is characterized in that being shaped on the handle groove that communicates with straight trough, be shaped on pin-and-hole in the groove, be provided with plectrum in the groove, be shaped on the plectrum and the corresponding circular hole of pin-and-hole, an end of latch passes circular hole and is inserted in the pin-and-hole, is shaped on groove and recessed edge on end cap, the recessed edge of end cap is corresponding with the groove of handle, the other end of latch is in the groove of end cap, and the front end of plectrum is between the symmetrical stops, and its rear end is in outside the recessed edge of end cap.

The utlity model has advantages such as simple in structure, easy to carry, that result of use is good, is a kind of economic, practical ratchet-type screwdriver.

In conjunction with the accompanying drawings and embodiments, specifically describe as follows to the utility model:

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is the primary structure exploded view of end cap and handle.

Fig. 3 is one of respective outer side edges figure of rotary body, stops and plectrum.

Fig. 4 be rotary body, stops and plectrum respective outer side edges figure two.

Fig. 5 be rotary body, stops and plectrum respective outer side edges figure three.

With reference to accompanying drawing: the utility model is by cutter hub 1, end cap 2 and handle 3 be combined intos.Three little concave points 4 of system in

end cap

2,5,6 and groove 7 And and on end cap 2, also be shaped on recessed edge 8, in the groove 12 of handle 3 rotary body 9 is housed, straight trough 14 in the handle 3 communicates with groove 12, symmetrical stops 10, spring 11 is placed in the straight trough 14, be shaped on the groove 15 that communicates with straight trough 14 on the handle 3, be shaped on pin-and-hole 16 in the groove 15, be provided with plectrum 18 in the groove 16, be shaped on the plectrum 18 and pin-and-hole 16 corresponding circular holes 20, one end of latch 17 can pass circular hole 20 and be inserted in the pin-and-hole 16, positioning bead 13 is housed on the handle 3, end cap 2 is with after handle 3 cooperates, the recessed edge 8 of end cap 2 is corresponding with the groove 15 of handle 3, the upper end of latch 17 in the groove 7 of end cap 2, positioning bead 13 can be respectively with end cap 2 on three little

concave points

4,5,6 match, the front end 19 of plectrum 18 is between the symmetrical stops 10, and its rear end 21 is in outside the recessed edge 8 of end cap 2.The utility model can come rotary end cover 2 in use as required, by the recessed edge 8 of end cap 2 and the mated condition that is used for adjusting plectrum 18 front ends 19 and stops 10 of plectrum 18 rear ends 21.When the front end 19 of plectrum 18 is in middle position, symmetrical stops 10 can be clamped rotary body 9 And and utilize the engagement of the two that rotary body 9 can not be rotated under the effect of spring 11, and when the front end 19 of plectrum 18 with 10 groups of the stops in left side during from rotary body 9, rotary body 9 can be done unidirectional clockwise turn, and counterclockwise during turn, the stops 10 in left side has left rotary body 9, rotary body 9 can't be blocked, also can't make workpiece do the displacement that screws in or screw out; When the front end 19 of plectrum 18 with 10 groups of the stops on right side during from rotary body 9, then rotary body 9 can be done unidirectional counterclockwise turn.
