Abstract

A thimble displaced ratchet wrench essentially comprises a wrench body which includes two ratchets, a control rod, a forced block, a rocked piece, and a thimble. The ratchets are mutually restricted properly with the thimble via the control rod and the rocked piece, thereby achieving multi-purpose effect. Furthermore, the two ratchets actuate with the pyramidal face of the forced block to disengage forcedly the resisted portion of the ratchet from the thimble, thereby being capable of displacing thimbles of different sizes. The thimbles with different sizes and modes are adaptable via the wrench body, and the displacement of the thimble is rather fast and simple, which can improve the adaptability of the ratchet wrench.

The specific embodiment

Relevant the utility model is for reaching above-mentioned purpose, the technology that is adopted, means and other effect, lift a preferable possible embodiments below and cooperate graphic detailed description as after, believe the above-mentioned purpose of the utility model, feature and other advantage, when can by one deeply specifically understand;

At first see also Fig. 1, Fig. 2, Fig. 5, shown in Figure 8, the anti-skid structure of a kind of closed hand-held tool that the utility model provides, force piece 40, a pendulum 50 and a sleeve 60 to be assembled by a wrench body 10, two ratchets 20, a control lever 30,, wherein:

This wrench body 10, have a head 11 and shank 12, wherein this head 11 has a combined hole 111 by a cover plate 13 cappings, and be communicated in the accommodation chamber 112 of combined hole 111, and being provided with the flexible latch closure body 113 of a tool in the wall of combined hole 111, this shank 12 is for the usefulness of user's gripping;

This two ratchet 20, the one end is a fastening part 21, and end is pivoting part 22 in addition, two ratchets 20 are hubbed in the accommodation chamber 112 of wrench body 10 accordingly by pivoting part 22, and be provided with elastic parts 23 (as spring) between the lateral surface of two ratchets 20 and accommodation chamber 112 walls, what these ratchet 20 controlled back fastening parts 21 can be in good time is protruding in the combined hole 111 of wrench body 10;

This control lever 30, its shaft section is the hexagonal shape, and the one end is press section 31, this control lever 30 is hubbed in the accommodation chamber 112 of wrench body 10, and between two ratchets 20, and its press section 31 is exposed to outside the head 11 of wrench body 10, is provided with an elastic parts 32 (as spring) and a dialing part 33 between press section 31 and wrench body 10 heads 11, wherein this elastic parts 32 can restore to the original state after making press section 31 pressurizeds automatically, and this dialing part 33 produces with moving control lever 30;

This forces piece 40, has a conical surface 41, this pressure piece 40 is fixedly arranged on the control lever 30, and it is moving together with this control lever 30, and its conical surface 41 corresponding two ratchets, 20 end faces, push this control lever 30, make of the gradient start of two ratchets 20, force in the accommodation chamber 112 of fastening part 21 dislocation wrench body 10 of two ratchets 20 along with the conical surface 41;

This pendulum 50, it is a waney lamellar body, this pendulum 50 is fixedly arranged on the control lever 30 and with control lever 30 and moves together, and between 20 corresponding 24 on two ratchets, and the periphery of ratchet 20 fits with 20 corresponding 24 on ratchet, rotate this control lever 30, this two ratchet 20 is pushed by pendulum 50, makes in good time protruding in the combined hole 111 of wrench body 10 of its fastening part 21;

This sleeve 60, form the locking holes 61 of different size in biend, and form ratchet 62 in all sides, and to ring cutting groove 63 that should latch closure body 113, this sleeve 60 is mounted on the combined hole 111 of wrench body 10 replaceablely, and the fastening part 21 and the ratchet 62 of this ratchet 20 are fastened, and are fastened on ring cutting groove 63 by flexible latch closure body 113, and it is more firm that wrench body 10 is combined with sleeve 60.The above is each main member correlation position of the utility model embodiment.

In order to clearly demonstrate flowing mode and the effect done of the present utility model, please cooperate Fig. 2 again, shown in Figure 3, because this two ratchet 20 is pushed by elastic parts 23, make its corresponding 24 periphery fit with pendulum 50, therefore, the user can with this dialing part 33 (as Fig. 8) to the right or left to pulling, make pendulum 50 along with dialing part 33 is pulled and start, 20 on this two ratchet is pushed by pendulum 50 outer rims and produces displacement, make in good time protruding of the fastening part 21 of two ratchets 20 at last in the combined hole 111 of wrench body 10, in other words, the fastening part 21 of this two ratchet 20 is along with dialing part 33 left sides, pull and in good time being fastened with sleeve 60 ratchets 62 on the right side, and sleeve 60 is just had, the use effect that backwards rotation changes.

Moreover, as shown in Figure 4, when user such as desire are changed the sleeve 60 of different size, form, only need dialing part 33 (as Fig. 8) is pulled to original position, by pushing of goods of furniture for display rather than for use 33 outer rims, the fastening part 21 that makes two ratchets 20 is in the accommodation chamber 112 of wrench body 10, and this moment, 21 ratchets 62 with sleeve 60 of fastening part of this ratchet 20 broke away from the sleeve 62 that displacement is suitable for so can comply with required.

Secondly, as Fig. 5, Fig. 6, shown in Figure 7, the user more can push the press section 31 of this control lever 30, make the pressure piece 40 on it produce interlock, this two ratchet 20 produces displacement along forcing piece 40 conical surfaces, 41 pushing of gradient, force the fastening part 21 of two ratchets 20 to be positioned at the accommodation chamber 112 of wrench body 10, and break away from the ratchet 62 of sleeve 60, can change the operation of sleeve 60, be with, only the press section 31 that need push this control lever 30 can be changed sleeve 60 immediately, to simplify the step of changing sleeve 60.

To sum up brief summary, the utility model be in order to simplify explanation, and with the unified explanation of the mode of two kinds of replaceable sleeves, and on actual fabrication, can intercept one of them displacement sleeve mode separately and make.

At last, as shown in Figure 8, the utility model is offered a locating slot 121 in shank 12 1 ends of this wrench body 10, establish in 121 groups of locating slots to connect a syllogic ratchet 70, and this syllogic ratchet 70 is made of jointly a core bar 71, two clamping blocks 72, a control loop 73 and 74 in ratchet cover; It is formed with two storage tanks 711 by this core bar 71, and this clamping block 72 that is pivoted respectively in this storage tank 711, and utilize the pendulum angle of this control loop 73 these clamping blocks 72 of control makes that it just has, the effect of backwards rotation or two-way stop; The principle spirit of above-mentioned syllogic ratchet be No. the 92202827th, referenced patent application case " improvement of syllogic ratchet device ", and its former patent also is all the utility model applicant and has.

In sum, the utility model can cooperate the sleeve of multiple different size, pattern by a wrench body, and the displacement of sleeve is considerably quick, simple and easy, really can improve the applicability of this ratchet spanner.
