Abstract

The utility model relates to an improved structure of the multi-purpose handle of wrenches and screwdrivers. The circumference of a connecting body 4 is provided with a slide groove 40; a convex point 50 corresponding to the slide groove 40 is arranged at the inner side of a sleeve cover 5; the sleeve cover 5 can be sheathed on the connecting body 4 in a rotational mode and is positioned by that the convex point 50 is clamped into the slide groove 40. The utility model can obtain favorable positioning effect; the handle body can swimmingly rotate for obtaining the effects of convenience and labor saving.

Description

Improved structure of multi-purpose handle of wrench and screwdriver

The utility model relates to a kind of handle of hand instrument, the structure-improved of particularly a kind of multiduty spanner, Screwdriver handle.

I have disclosed a kind of multiduty spanner in Chinese patent application (application number is 94216909,3), Screwdriver handle, its structure is consulted shown in Figure 1, tie up to the affixed junctor 2 of a handle body 1 one ends, the other end of this junctor 2 then is provided with junction surface 20, like this can be on this junction surface 20 in time sheathed various bottle opener instruments, as shown in Figure 2, be beneficial to the work of carrying out.But because the location action of its structure when not having suitable member with auxiliary operation, thus when operational motion, how with one-handed performance, thus on using quite not smoothly, and also therefore can't the application of force excessive, to avoid causing screwdriver head 21 and working substance disengaging.But if again with another hand grab handle body 1 or junctor 2 one ends, during with auxiliary movement, then again because of this handle body 1 fixes as one with junctor 2, so in case grip tension then difficult the rotation, it is uncertain that too pine then still makes the location.In addition, utilize this structure to be locked or when disassembling the set screw of an object surface below, because the position of this screw is not good, the body and face upward head and see and look this screw position so most operators can squat down, mode of operation is not only uncomfortable but also be inconvenient to lock, disassemble.When carrying out work, often cause the situation of separating again with screw owing to the application of force is improper if do not squat down body in addition.So this structure is still very inconvenient in use, thereby influences service efficiency.

The purpose of this utility model is to provide a kind of locating effect stable, really, and rotate smooth and easy, easy to operate, the structure-improved of the multiduty spanner in labour-saving, Screwdriver handle.

The utility model is to realize by following technical solution: this lever structure-improved mainly sets firmly a junctor by a handle body one end and is constituted, and all side surfaces of its junctor appropriate position offers a chute; The set chute system of the corresponding junctor of one upper shield inner surface is provided with gives fixed number purpose salient point; Upper shield is installed on the junctor rotationally, and snaps in the chute with each salient point.

The utility model is the recreation to my patent application, because the improvement of structure makes it that significant progress be arranged on locating effect, and therefore impels it in locking or when disassembling the not good screw in position, more can obtain splendid operational motion effect.It is more stable, certain, easy to operate, laborsaving to have locating effect, characteristics such as service efficiency height.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Embodiment 1

Consult shown in Figure 3ly, this creation mainly is to be formed by a handle body 3, a

junctor

4 and 5 common combinations of a upper shield, and wherein, this handle body 3 is textural to be as good as with original structure, and its assembling with 4 of this junctors is also identical with original structure, so all seldom say at this and to give unnecessary details.

As for this junctor 4, its all sides appropriate location system offers a chute 40, on the inner surface of this upper shield 5 then to should junctor 4 set chutes 40, system is provided with gives fixed number purpose salient point 50, consult shown in Figure 4, so this upper shield 5 can be set on this junctor 4 rotationally, and utilize this each salient point 50 to snap in this chute 40, make this upper shield 5 must with this junctor 4 formation one of interosculating.

Consult shown in Figure 5, manipulating of this creation, be can be earlier in the set fit portion 41 of these junctor 4 front ends the suitable driving end 42 of installing one, the operator can be held on this upper shield 5 on the other hand then, another is held and is held in this handle body 3 one ends, and press mutually with a working substance (not shown) with this driving end 42 and to combine, and then give PROPEL again, at this moment, because the operator grips simultaneously with two hands, operation, so when these handle body 3 rotational action, the cause of this junctor 4 because of setting firmly mutually with this handle body 3, and rotate simultaneously thereupon, as for 5 grippings that the operator is arranged because of the outside of this upper shield, and inboard each set salient point 50 just snaps in the set chute 40 of junctor 4, so junctor 4 can see through cooperating of chute 40 and each salient point 50, and can in upper shield 5, rotate smoothly, and unlikely drive upper shield 5 rotates thereupon, in other words, this upper shield 5 is not because of participating in rotational action and being inactive state, so the kind state can help the location action when operation, make its effect more stable, really, secondly, also because this creation can have the preferred positioning effect, thus unlikelyly when the application of force break away from working substance easily, that is, can impel application of force effect more to improve by this, to reach convenient, the labour-saving effect.

Embodiment 2

Consult shown in Figure 6, it is to install a screwdriver heads 43 in this fit portion 41, so because the operator can second-handly be held on handle body 3 and the upper shield 5 respectively, so when screwdriver heads 43 and screw 44 press when combining, can make this creation be able to stable position by the hand that grips this upper shield 5, this moment, another hand then can give the application of force, impel screwdriver heads 43 to be pressed on the head of screw 44, thus, because existing advantages of good positioning effect between this creation and the screw 44, when so further application of force handler body 3 moves, also not having because of the application of force is improper causes screwdriver heads 43 to separate with screw 44, in other words, the operator if before action beginning with this creation positively with after working substance combines, can rotate swimmingly, and the body of can not must squatting down is again looked combining of screwdriver heads 43 and screw 44 with sight, the action situation, so more convenient in the use, and can improve its practical value.

Claims

A kind of multiduty spanner, Screwdriver handle structure-improved mainly set firmly a junctor 4 by a handle body 3 one ends and are constituted, and it is characterized in that junctor 4 all side surfaces appropriate positions offer a chute 40; One upper shield, 5 inner surfaces to should junctor 4 set chutes 40, system is provided with gives fixed number purpose salient point 50; Upper shield 5 is installed on the junctor 4 rotationally, and snaps in location in the chute 40 with each salient point 50.
