Description

The ratchet spanner instrument of convertible hand, electric operating pattern

Technical field

The utility model relates to Wrench, is meant that especially a kind of being available for users to select to carry out the dismounting operation with manual or electrically operated mode driven tool head, and then reaches the convertible hand that is easy to map function, the ratchet spanner instrument of electric operating pattern.

Background technology

See also Fig. 1, the ratchet spanner instrument of available dynamic, it is to set firmly a ratchet lever 20 at lever 10 1 ends, the front end of ratchet lever 20 then is a pawl seat 21, has a motor by drive power source in the lever 10, to drive the assembly start in the pawl seat 21; See also Fig. 2, offer profile groove 210 in the middle of the pawl seat 21, and make both sides form a left side, right folder frame 211,212, left side folder frame 211 offers path perforation 213, right 212 of frames of folder offer big footpath perforation 214, one rotating shaft, 22 1 ends are attached at motor, the other end then has eccentric shaft 221, rotate to drive a drive block 222, one pulling piece 23 is provided with pod 231 and interior ring ratchet 232, utilize pod 231 sheathed drive blocks 222, make rotating shaft 22 when rotating, can drive pulling piece 23 by eccentric shaft 221 and make reciprocal rotary oscillation, one ratchet head 24, the one end has start post 241, the other end then has direction button 242, described direction button 242 can be controlled the brake 243 in the ratchet head 24, with the stopper direction of control brake 243 with the interior ring ratchet 232 of pulling piece 23, and the operation that selection is just being changeed or reversed, after ratchet head 24 has the sheathed spring shim 25 of direction button 242 ends, be located in the path perforation 213 of left side folder frame 211, behind the then sheathed pad 26 of start post 241 ends, be fastened on C in the right folder frame big footpath perforation 214 ring side grooves 215 with one and buckle 27 spacingly, and finish the assembling location; See also Fig. 3, when making pulling piece 23 make the rotary oscillation of forward when rotating shaft 22 rotations, because brake 243 and interior ring ratchet 232 clips, and the start post 241 that can drive ratchet head 24 rotates, only when pulling piece 23 is done reverse backswing, interior ring ratchet 232 is can push in the brake 243 to contract, and the stroke that work oppositely dallies, when making the rotary oscillation of forward once more in order to do profit, the start post 241 that drives ratchet head 24 again rotates, it should be noted that, when the idle running stroke is made in pulling piece 23 reverse backswing, ratchet head 24 must maintain static, otherwise in company with pulling piece 23 reverse backswing, can't unscrew or screw the operation of workpiece, yet, make ratchet head 24 fixed modes, be to rely on the elastic force of spring shim 25 to be shored, come to buckle 27 frictional force that produce with C with the internal face 216 of left side folder frame 211, make ratchet head 24 maintain static, but when pulling piece 23 is done the swing work done of forward, pulling piece 23 because of again with brake 243 clips, and be easy to overcome described frictional force, and then the start post 241 rotation works done of drive ratchet head 24, anyway, frictional force is essential, do the forward work done in when swing but can not excessively have influence on pulling piece 23, therefore moderate frictional force is extremely important.

Yet the Wrench of described kind of power still has following shortcoming on transmission or use kenel:

Its rotating shaft 22 that is driven by motor is to drive pulling piece 23 with eccentric shaft 221 to do reciprocal forward and reverse swing, again by the ratchet clip effect of brake 243 with interior ring ratchet 232, and drive and idle running driving pawl head 24 starts that hocket that reset with clip, the action that described idle running resets promptly causes the consume on the motor power.

Drive the motor that rotating shaft 22 is rotated, be to be easy to very much control do forward and reverse rotation and change, so that switching, ratchet head 24 turns to start, the only design of described power operated wrench instrument, it is the ratchet clip effect of ring ratchet 232 in cooperating with brake 243 with direction button 242, reach switching and turn to start, cause the complexity on the switching controls on the contrary.

The design of described power operated wrench instrument, be only can drive start with motor, in the time of only can't making revolution when being short of power, described power operated wrench instrument will can't use fully in start, and only be useful in the operator scheme of power, so still be apparent not enough on the utilization benefit.

In view of this, the utility model people then is engaged in the research and development and the making experience of relevant industries for many years with it, at the present problem further investigation that faces, through the research of long-term endeavour with study, grind the ratchet spanner instrument of creating a kind of convertible hand, electric operating pattern eventually, significantly to improve existing scarce fraud, this is design aim of the present utility model.
