The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
This ratchet spiral shell that turns to is criticized, and comprises handle 6, is connected in the joint 5 of handle 6 front ends, and these joint 5 front ends are plugged with spiral shell and criticize bar 1, and spiral shell is criticized the jack that bar 1 front end has socket joint spiral shell screwdriver bit.Joint 5 is coupling in handle 6 by locating shaft 19, and this locating shaft 19 is hexagon socket head cap screws.Handle 6 front ends have mounting groove 6a, and described joint 5 one ends have the connecting portion 5a that is complementary with this mounting groove 6a, and this connecting portion 5a is positioned at mounting groove 6a, and locating shaft 19 passes this connecting portion 5a.Its bottom of connecting portion 5a is curved and be provided with square tooth 5b.But handle 6 is provided with the position-limit mechanism that limiting joint 5 rotates.This position-limit mechanism comprises locating piece 20, spring 21, and handle 6 is provided with radial groove 22 below connecting portion 5a, these radial groove 22 1 end pass-out handles 6 sidewalls; Locating piece 20 is located to be in this chute 22 and with this chute 22 and is slidingly matched; These locating piece 20 1 ends stretch out handle 6 sidewalls, and the other end peaks at chute 22 inner ends by spring 21; Locating piece 20 has the protuberance 20a that cooperates with connecting portion 5a arc bottom.Protuberance 20a blocks square tooth 5b, can it can not be rotated joint 5 location.
During use, locating piece 20 is stretched out outer one of chute press, protuberance 20a promptly breaks away from square tooth 5b, and connecting portion 5a is promptly unrestricted, and joint 5 can rotate around locating shaft 19, drives spiral shell and criticizes that bar 1 rotates, the conversion operating angle.After spiral shell criticized bar 1 and be transferred to required angle, unclamp locating piece 20, by the effect of spring 21, locating piece 20 resets, and protuberance 20a blocks square tooth 5b again, and joint 5 can not rotate promptly by spacing again.This moment, spiral shell was criticized the work of getting final product.The mounting groove 6a of handle 6 blocks connecting portion 5a, and it can not rocked, and helps the use that spiral shell is criticized.
Joint 5 front ends have installing hole, and spiral shell is criticized bar 1 and is plugged in the installing hole, and installing hole bottom is provided with first steel ball 13, and spiral shell is criticized the end face that bar 1 is positioned at installing hole one end and contacted with this first steel ball 13, is convenient to spiral shell and criticizes the bar rotation.Spiral shell is criticized the end that bar 1 is positioned at installing hole and is connected with ratchet 14, joint 5 has two radial direction through hole 17 at the installing hole sidewall, two ratchet 10 are located in the through hole 17 to be the mode that is slidingly matched with through hole 17 respectively, match with ratchet 14 in the inner of this ratchet 10, ratchet 10 is provided with return unit, return unit is the jump ring 9 that is around in joint 5 outer walls, and the end of this jump ring 9 is stuck in the outer end of two ratchet 10 respectively.Joint 5 outer walls have draw-in groove 16, and described jump ring 9 is around in this draw-in groove 16.The front end face of joint 5 is provided with ratchet shift fork 2, and the front end face of joint 5 has aperture, is provided with second steel ball 11 and stage clip 12 in this aperture, and stage clip 12 1 ends peak at the aperture bottom, and the other end peaks at second steel ball, 11 bottoms; Ratchet shift fork 2 contacts with joint 5 front end faces by second steel ball 11, is convenient to ratchet shift fork 2 and rotates.Ratchet shift fork 2 has the annular shift fork portion 15 of stretching in the installing hole, and the two ends of this shift fork portion 15 are butted on the inner of two ratchet 10 respectively.Ratchet shift fork 2 outsides are provided with turning sleeve 4, and this turning sleeve 4 is sheathed on spiral shell and criticizes on the bar 1 and with ratchet shift fork 2 and fixedly connected.Turning sleeve 4 is provided with hasp, and described ratchet shift fork 2 is provided with the bayonet socket that matches with this hasp, and this turning sleeve 4 is provided with the mark that shows ratchet shift fork 2 rotational angles, and that this mark is indicated respectively is left-handed, dextrorotation and the motionless three kinds of states of center fixed.Turning sleeve 4 is fixedly connected by cooperating of hasp, bayonet socket with ratchet shift fork 2, and turning sleeve 4 rotates and can drive 2 rotations of ratchet shift fork.Joint 5 sidewalls have locating hole, are provided with alignment pin 3 in this locating hole; Spiral shell is criticized and is had the annular positioning groove 18 that is complementary with this alignment pin 3 on the bar 1, and alignment pin 3 inserts in locating slot 18, makes spiral shell criticize bar 1 and can not come off outward.Handle 6 inside have cavity, and this cavity flap has tail-hood 8.Cavity can be saved material, can also carry things such as spiral shell screwdriver bit in it.Be with rubber handle crust 7 on the handle 6.
When two ratchet 10 all are in original position, can ratchet 14 twocoueses are spacing, spiral shell was criticized bar 1 and was maintained static this moment, and the mark on the turning sleeve 4 is shown as stationary state; Rotation turning sleeve 4 drives ratchet shift fork 2 and rotates, and a ratchet 10 can be released by its shift fork portion 15, but this moment, spiral shell is criticized bar 1 folk prescription to turn; Toward back rotation ratchet shift fork 2, another ratchet 10 is released, and previous ratchet 10 is because the effect of jump ring 16 resets, spiral shell was criticized bar 1 and was got final product opposite spin this moment again.
