Abstract
The utility model relates to a tool grab handle without a coupling part. The tool grab handle is an integrated structure and is provided with a tool combination part. The flange of the grab handle is equipped with at least one groove extending along the direction of the long shaft of the grab handle. The groove of the grab handle is connected with the flange of the grab handle by an arc chord angle. The utility model has the efficacy of enabling the user to steadily grasp the grab handle and operate the tool.
Description
Technical field
The utility model relates to a kind of hand-operated tools, relates in particular to a kind of tool handle of not having a cover portion that firmly grips the lever operation tool for the user.
Background technology
As shown in Figure 3, be existing a kind of tool handle structure, it has a holding rod 81 of being made by metal material usually, has an inserting part 82 in the holding rod 81, for plant set of tools 9A or 9B, and holding rod 81 is provided with a spring 83 in inserting part 82, and inserting part 82 front ends are provided with stopper 84, ends set of tools 9 for card.Holding rod 81 outer rims wear holding of plastics or rubber material and overlap 85, for user's hand gripping.
When using the set of tools 9A of spanner form, when the user is gripped on cover 85 operation tool group 9A, be to hold cover 85 and holding rod 81 with the mode application of force drive of reciprocally swinging, at this moment, has suitable length formation force arm owing to hold cover 85 with holding rod 81, therefore, even if user's hand attaches a little oil stain, can not make hand yet and hold cover 85 generation slippages.But when using the set of tools 9B of bottle opener form, the user holds the action of cover 85 application of force operation tool group 9A, just can become is to rotate the form of holding cover 85 and holding rod 81, in the case, because it is rounded holding the section configuration of cover 85, therefore, when user's hand attaches oil stain, just make hand easily and hold 85 generations of cover and skid, and be unfavorable for application of force operation tool group 9B.
Moreover, because holding rod 81 overlaps 85 combining form with holding, be two kinds of forms that unlike material wears mutually, therefore, after using a period of time, holding rod 81 with hold the conjugation that overlaps 85 just can variation, in such cases, the user firmly holds cover 85 when coming operation tool group 9A or 9B, holds cover 85 and 81 of holding rods and just can produce slippage, and be unfavorable for manipulating.
The utility model content
Can produce slippage in order to overcome holding between cover and holding rod that existing tool handle exists, and be unfavorable for that the shortcoming manipulated, the utility model provide a kind of tool handle of not having a cover portion, it has the effect that firmly grips the lever operation tool for the user.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of tool handle of not having a cover portion is characterized in that, the structure that is formed in one, and it has an instrument joint portion, and its outer rim is concaved with at least one groove that extends along the long axis direction of lever.
Aforesaid tool handle of not having a cover portion, wherein the groove of lever and this lever outer rim are with the arc chord angle intersection.
The utlity model has the effect that firmly grips the lever operation tool for the user.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an exploded perspective schematic diagram of the present utility model
Fig. 2 is a lever cutaway view of the present utility model
The schematic appearance of the existing instrument of Fig. 3
The specific embodiment
See also Figure 1 and Figure 2, the utility model is not had a tool handle of cover portion, the structure that this lever 1 is formed in one, this lever 1 has an instrument joint portion 11, for set of tools 2,3 combinations, and a spring 12 is set in this instrument joint portion 11, and instrument joint portion 11 front ends are arranged with two stoppers 13, end set of tools 2,3 for card.The outer rim of this lever 1 is concaved with at least one groove 14 that extends along the long axis direction of this lever 1.In the present embodiment, be to be arranged with a groove 14 respectively in the position of corresponding two stoppers 13 of lever 1 outer rim, each groove 14 is with arc chord angle 15 intersections with this lever 1 outer rim.
When the set of tools 2 of using the spanner form, when the user is gripped on lever 1 operation tool group 2, it is mode application of force drive lever 1 with reciprocally swinging, can form force arm owing to lever 1 has suitable length this moment, therefore, even if user's hand attaches a little oil stain, can not make between hand and the lever 1 yet and produce slippage.
And grip lever 1 application of force when operating another set of tools 3 as the user, and the action of its application of force, just can become is the form of rotating lever 1, under this situation, because lever 1 outer rim has the frictional force of groove 14 can increase user's hand and hold lever 1 time.Therefore,, can not produce 1 problem of slip of user's hand and lever yet, make the user can firmly grip lever 1 and come application of force operation tool group 3 even if user's hand attaches some oil stains.
Moreover, lever 1 of the present utility model is the structure of integral type, uses for a long time again, also can not take place as existing handle structure because of holding rod and the conjugation variation of holding cover, and holding rod produces the situation of slippage with holding cover when causing the application of force, and all consistent from start to finish good grip steadiness can be provided.
In sum, the utility model is arranged with the structure of groove 14 in integrated lever 1 outer rim, can increase users by groove 14 and grip the frictional force of lever 1 when rotating, and firmly grips the effect that lever comes operation tool to reach the user.
