Abstract

The utility model discloses a pair of arc-shaped tongs. A rod-shaped tong body is adopted; the arc-shaped tongs comprise a first tone arm, a second tong arm, a first jaw and a second jaw, wherein the first tong arm and the second tong arm are hinged through a main shaft; sector racks are arranged at the upper parts of the first tong arm and the second tong arm; the first jaw and the second jaw are movable, have dovetail groove structures, and are embedded with circular arc-shaped anti-skid fixture blocks; the first jaw and the first tong arm are fixedly connected through a first bolt; the second jaw and the second tong arm are fixedly connected through a second bolt; horizontal guide slots are formed in the rear parts of the first jaw and the second jaw; stirring wheels are placed in the guide slots; the other ends of screws fixedly connected with the stirring wheels are fixedly connected with the first jaw and the second jaw; when the stirring wheels are stirred, the first jaw and the second jaw can be moved in the guide slots in a bidirectional manner. The arc-shaped tongs are simple in structure and convenient to use, and can save more effect and has better advantages when clamping a large-sized object.

Description

Arc clamping clip

Technical field

The utility model relates to hardware & tools technical field, relates in particular to arc clamping clip.

Background technology

Hardware is conventional instrument in production and life, and wherein pliers is most widely used.But the pliers of every day use adopts V-arrangement mostly, because the component outside oriented jaw exists, can produce outside slippage power in use.When clamp cylinder type objects, the object volume being held is like this larger, and jaw opens just larger, also less for clamping the component of object, and more built on the sand.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy and convenient and clamp firm pliers.

The utility model is realized by the following technical solutions: adopt shaft-like caliper, comprise the first tong arm and the second tong arm, the first jaw and the second jaw, the first tong arm and the second tong arm are by hinged at main shaft, the first tong arm and the second tong arm top arrange sector rack, the first described jaw and the second jaw are moving jaw, and the structure that the first described jaw and the second jaw are dovetail groove is embedded with the anti-skidding fixture block of circular arc; The first jaw is fixedly connected with by the first bolt with the first tong arm, the second described jaw is fixedly connected with by the second bolt with the second tong arm, the rear portion of the first jaw and the second jaw all has horizontal guide slot, the built-in thumb wheel of gathering sill, the screw rod other end being fixedly connected with thumb wheel is fixedly connected with the first jaw and the second jaw, stir thumb wheel, can make the first jaw and the second jaw way moving in gathering sill.

As preferred technical scheme, the anti-skidding fixture block of described circular arc adopts quality of rubber materials to make.

By using the beneficial effects of the utility model: while preparing clamping cylinder class article, the rear portion of passing through be located at the first jaw and the second jaw all has horizontal guide slot and thumb wheel and screw acting, fine-tuning two jaw distances, guarantee the anti-skidding fixture block of zigzag and the complete close contact of article to be held on the first jaw and the second jaw, after picking up, be difficult for slippage.It is all constant utilizing the moving principle of tooth to make the direction size of clamp power, more has superiority clamp larger volume object is more laborsaving, and it is simple in structure, easy to use.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

In the present embodiment, with reference to adopting shaft-like caliper shown in Fig. 1, bag adopts shaft-like caliper, comprise that the first tong arm 1 and the second tong arm 2, the first jaws 3 and the second jaw 4, the first tong arms 1 and the second tong arm 2 are by hinged at main shaft 5, the first tong arm 1 and the second tong arm 2 tops arrange sector rack 11, the first jaw 3 and the second jaw 4 are moving jaw, and the structure that the first described jaw 3 and the second jaw 4 are dovetail groove, is embedded with the anti-skidding fixture block 10 of circular arc; The first jaw 3 is fixedly connected with by the first bolt 6 with the first tong arm 1, the second described jaw 4 is fixedly connected with by the second bolt 7 with the second tong arm 2, the rear portion of the first jaw 3 and the second jaw 4 all has horizontal guide slot 8, the built-in thumb wheel 9 of gathering sill, the screw rod other end being fixedly connected with thumb wheel is fixedly connected with the first jaw 3 and the second jaw 4, stir thumb wheel 9, can make the first jaw 3 and the second jaw 4 at the interior way moving of gathering sill 8.

Wherein, the anti-skidding fixture block 10 of circular arc adopts quality of rubber materials to make.

While preparing clamping cylinder class article, the rear portion of passing through be located at the first jaw and the second jaw all has horizontal guide slot and thumb wheel and screw acting, fine-tuning two jaw distances, guarantee the anti-skidding fixture block of zigzag and the complete close contact of article to be held on the first jaw and the second jaw, after picking up, be difficult for slippage.It is all constant utilizing the moving principle of tooth to make the direction size of clamp power, more has superiority clamp larger volume object is more laborsaving, and it is simple in structure, easy to use.

Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these are revised and within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
