Abstract

The utility model discloses a rotary filter spanner, comprising a clamping band which adopts single material and is provided with a plurality of small convex columns formed on the inner surface. The convex columns can be smooth conical, cylindrical, or square cylindrical, and the arrangement of the columns can be regular or irregular. Compared with the previous products of the same category, the clamping band of the product can produce more friction force under the same given force, and the articles can be held more firmly without the phenomenon of slipping even under the situation of oil stain. At the same time, as the convex columns used for increasing friction force are directly formed on the clamping band, an extra anti-skid layer is omitted in order to save raw material and reduce cost, and thus the structure is much simpler.

Description

Spinning filter spanner

Technical field

The utility model relates to a kind of hand tools, specifically, relates to a kind of spanner that uses on the pipe workpiece.

Background technology

Utility model patent 93224160.3 discloses a kind of spinning filter spanner, as shown in Figure 1, it comprise handle 1, inner surface be provided with the clamp 2 of rubber antiskid piece 5, clamp be with 3 '; The inner surface of non-slipping block 5 is a circular arc, which is provided with parallel convex tooth strips, and the frictional force when holding with a firm grip to increase spanner makes the spanner can slippage when work; Clamping has the skid resistant course of rubber mass with 3 ' upward hoops, and the inner surface of skid resistant course also is provided with parallel convex tooth strips, the frictional force when order ground also is increase work, and the outside of skid resistant course is smooth; Handle 1 is a hollow structure, and its back side offers several draw-in grooves 4, and non-skid band 3 ' one ends are coupling at the inner face of handle, and the other end can be fixed on the different draw-in grooves according to the size of grasping object; The shape approximation of clamp is in triangle, and its top is coupling in the upper end of handle back side draw-in groove.This spinning filter spanner can be put into suitable draw-in groove with the free end that clamps band according to the size of grasping object in use, and clamp 2 also can rotate to be suitable for the size of object simultaneously, and is easy to use, high efficiency.But since this spanner what add that the taut band inner surface adopts is the convex tooth strips structure, this structure applies same power with bigger by the contact-making surface of grasping object, the pressure that produces on the unit are is less, therefore skids easily; Simultaneously because spinning filter spanner is the dismounting that is used for oil filter, cleaner on the various motor vehicles basically, therefore clamp band and inevitably can touch greasy dirt, greasy dirt is infected with on the skid resistant course of rubber material, has quickened the aging of skid resistant course, makes the service life of product impaired.

Summary of the invention

Technical problem to be solved in the utility model be provide a kind of at above-mentioned prior art present situation and increased clamping force, more anti-skidding spinning filter spanner when using.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of spinning filter spanner, comprise adding taut band, and it is characterized in that the described inner surface that adds taut band is provided with several small convex pillars.

Described small convex pillar can also can be a rectangle or foursquare for the taper shape of slyness, cylindrical or its cross section.

Described small convex pillar can be regularly arranged, also can irregular alignment.

Compared with prior art, advantage of the present utility model is:

1, because to clamp the anti-skidding of band is to have adopted small convex pillar, rather than convex tooth strips, so during spanner work, it is bigger to clamp the frictional force that band produces, even having under the situation of greasy dirt, also skidding can not occur.

2, because small convex pillar is to be molded directly within the inner surface that stainless steel clamps band, the ageing of rubber phenomenon that is produced in the time of therefore can not occurring adopting the rubber ferrule layer has increased service life of spanner.

3, saved the skid resistant course that adds on the taut band, saved raw material, reduced cost, structure is simpler.

Fig. 2 is the side view of Fig. 2.

Fig. 3 is the structural representation of the utility model background technology.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing, but the utility model is not limited in following embodiment.

As shown in Figure 3, spinning filter spanner comprises that handle 1, clamp 2 and clamping be with 3, and wherein the back side of handle 1 is provided with 3 draw-in grooves 4 that are similar to down " V " shape, and the number of draw-in groove also can be provided with one or more as required; The shape of clamp 2 is similar to triangle, and its top is coupling on the top of handle 1, and corresponding sides are provided with the non-slipping block 5 of rubber mass; The inner surface of non-slipping block 5 is circular-arc, is operated object so that can better be adjacent to when work, and the shape of non-slipping block 5 inner surfaces can change according to the difference of being grabbed body surface, is not limited in circular arc; Also be provided with parallel convex tooth strips on the inner surface of non-slipping block, the frictional force of grasping when working to increase spanner.

Add taut band 3 for having the stainless steel band of certain width, certainly, also can use the material of other quality as required; Form slick and sly conical small convex pillar on its inner surface, as depicted in figs. 1 and 2, the shape of small convex pillar also can be used cylindrical or square column type or other irregular shape, all is to get; The present embodiment small convex pillar is the matrix of rule to be arranged, certainly according to the needs that use, and also can be with they irregular alignments; An end that adds taut band 3 is connected on the inner face of handle by bearing pin, and the other end is a free end, can be buckled in different falling in " V " shape draw-in groove as required.

During use, insert clamping in the cavity of handle upper end with 3 free end, and according to the suitable draw-in groove of diameter selection of being grabbed object, the free end buckle that will add taut band wherein, adjust the angle of clamp, the annulus that the three is formed tightly is enclosed within by on the dismounting thing, at this moment, turning handle firmly can reach the purpose of dismounting article.

Claims

1, a kind of spinning filter spanner comprises adding taut band, it is characterized in that the described inner surface that adds taut band is provided with several small convex pillars.

2, spinning filter spanner according to claim 1 is characterized in that described small convex pillar is slick and sly taper shape.
