Abstract

An improved handle structure of hand tool comprises two bodies mutually pivoted. One end of each body is respectively a wrenching part which can clamp object when the two bodies are pivoted. The middle section of each body is equipped with a pivoting part for mutually pivoting. The section of each body far away from the wrenching part is equipped with a handle part. The outer edge of each handle part is provided with a sliding cover. Each sliding cover can slide on each handle part to add the length of the handle part. With the adding length of the handle part of the hand tool, the utility model causes an operation end to away from a working end, and possesses the function of slip limiting so that the utility model has practicability to achieve the effects of labor saving and narrow space inserting.

Description

Improved hand tool shank structure

Technical field

The utility model relates to a kind of hand-operated tools, relates in particular to a kind of on-slip function that has, and makes hand-held tool have more practicality, and reaches laborsaving and go deep into the improved hand tool shank structure of narrow space.

Background technology

As shown in Figure 7, be existing hand-held tool 7, it is made up of a clamping part 71, an articulated section 72 and a shank part 73.

This shank part 73 all is provided with on-slip cover 74 usually, and it is in order to prevent hand and 73 slippages of this shank part; But if when meeting narrow space, then can be, and cause the shortcoming that can't be clamped to workpiece because of shank part 73 curtailments of hand-held tool, during at this moment as with the hand-held tool of large-size, then can can't enter narrow space because of clamping part 71 increases, inconvenience is quite arranged.

In sum, existing hand tool shank structure, in the use have inconvenience more, and in addition improved necessity is arranged.

The utility model content

In order to overcome the above-mentioned shortcoming that existing hand-held tool exists, the utility model provides a kind of improved hand tool shank structure, because the shank part of hand-held tool can increase length, make the operating side away from the working end, and still has the on-slip function, make hand-held tool have more practicality, and reach laborsaving and go deep into the effect of narrow space.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of improved hand tool shank structure is articulated mutually by two bodies and to form, and an end of each body is respectively a pincers portion, when being pivoted relative to each other, two bodies can press from both sides the object of pulling, and the stage casing of each body is respectively an articulated section, and for articulating mutually, each body is a shank part away from a section of pincers portion; It is characterized in that: described each shank part outer rim is set up a sliding sleeve, and each sliding sleeve can slide on each shank part, to increase the length of shank part.

Aforesaid hand tool shank structure, wherein the two opposite outer of the contiguous described articulated section of each shank part is provided with a groove, for each sliding sleeve tenon inlay card.

Aforesaid hand tool shank structure, wherein each shank part is provided with a protuberance away from an end of described articulated section, for each sliding sleeve tenon inlay card.

Aforesaid hand tool shank structure, wherein relative two inboards of the contiguous described articulated section of each shank part are provided with a return unit.

Aforesaid hand tool shank structure, wherein return unit is a compression spring.

Aforesaid hand tool shank structure, wherein return unit is a magnetite group.

The beneficial effects of the utility model are, because the shank part of hand-held tool can increase length, make the operating side away from the working end, and still have the on-slip function, make hand-held tool have more practicality, and reach laborsaving and go deep into the effect of narrow space.

The specific embodiment

See also Fig. 1 to Fig. 3, present embodiment is a kind of improved hand tool shank structure, it is articulated mutually by two bodies 11,12 forms, one end of each body 11,12 is respectively a pincers portion 13,14, two bodies 11,12 can press from both sides the object of pulling when being pivoted relative to each other, and the stage casing of each body 11,12 is respectively an articulated section 15, and with mutual pivot joint, two bodies 13,14 are respectively a shank part 16,17 away from a section of this pincers portion 13,14.Wear a sliding sleeve 18 in the mode that can slide relatively respectively in each shank part 16,17 outer rim, each sliding sleeve 18 can be slided on each shank part 16,17, and increase the length of shank part 16,17.End in each shank part 16,17 contiguous these articulated sections 15 of this two body 11,12 wears by an alignment pin 19 respectively and articulates and make each shank part 16,17 can reach bending to adjust effect.The two opposite outer of each shank part 16,17 contiguous these articulated section 15 is provided with a groove 20, tenon 21 inlay cards for each sliding sleeve 18, and be provided with a protuberance 22 away from an end of this articulated section 15 at each shank part 16,17, the tenon 21 of each sliding sleeve 18 of confession fixes when stretching, and can not break away from each shank part 16,17.In the present embodiment, each sliding sleeve 18 is to adopt clad type, and each sliding sleeve 18 is to coat each shank part 16,17 to the bending place, and relative two inboards of each shank part 16,17 contiguous these articulated section 15 are provided with a return unit 23.In the present embodiment, this return unit 23 is a compression spring.

When the operator tool work, as run into narrow space, protuberance 22 directions of each sliding sleeve 18 of the utility model towards each shank part 16,17 can be stretched, make the tenon 21 of each sliding sleeve 18 break away from this groove 20, make each sliding sleeve 18 slide onto this protuberance 22 along each shank part 16,17, each shank part 16,17 length is increased, can go deep into the action that narrow space is done clamping.When work is finished, sliding sleeve 18 can be pushed back towards these articulated section 15 directions, make each tenon 21 be fastened in each groove 20, and make each shank part 16,17 extensive original length of covering into, so that carry and place.

If when the operator tool work, apply as need and could rotate more energetically or when cutting off workpiece, also each sliding sleeve 18 can be skidded off along each shank part 16,17, to increase force arm, so can be more laborsaving when driving workpiece.

In sum, the utility model overcomes existing hand-held tool curtailment and causes at small space and can't be clamped to workpiece, or is difficult for the shortcoming of rotating, and still has the on-slip function, reaches the practicality that promotes this product, and improves operating function.

Certainly, still there are many embodiment in the utility model, therebetween the only variation on the details.See also Fig. 4 to Fig. 6, it is second embodiment of the present utility model, wherein each sliding sleeve 18 is to adopt half clad type, and each sliding sleeve 18 is to be slidedly arranged on the set chute group 25 of each shank part 16,17 to move, and this return unit 24 is a magnetite group, so, also can reach identical effect with aforementioned first embodiment.
