Abstract

The utility model relates to a universal clamp, which belongs to a lab tool component and is mainly used for clamping vessels in chemical experiments. The utility model can solve the problems of complicated operation and unreasonable structure of existing universal clamps and has the advantages of simple operation and reasonable structure. The utility model comprises a bushing and has the technical proposal that a hand wheel at the back part of the bushing is connected with a screw nut in a clamping jaw base in the front part of the bushing via a screw thread on a connecting rod. A sharp part at the front end of the screw thread on the connecting rod is respectively contacted with a tail short arm of the clamping jaw on a shaft which is fixed in the clamping jaw base, and a spring is arranged between the long arms of the clamping jaw.

Description

A kind of extension clamp

Technical field:

The utility model is to belong to breadboard tool piece, is mainly used in holding vessels in the chemical test.

Background technology:

Existing be used to test omnipotent accompanies multiplely, and structure is that rod member is provided with two jaws usually, and jaw is provided with one or two and adjusts bolt; Therefore during use, the turn bolt makes the jaw on the bolt move, clamp container one by one, operates cumbersomely, and operating efficiency is not high; In addition,, pressed from both sides container not necessarily on the center line of rod member, influenced the stability of container because structure is unreasonable.

Summary of the invention:

The utility model solves present extension clamp troublesome poeration exactly, and the problem that structure is unreasonable provides a kind of extension clamp simple to operate, rational in infrastructure.

The purpose of this utility model is achieved in that the utility model comprises sleeve pipe, its structural feature is that the handwheel at sleeve pipe rear portion links to each other with the nut in the jaw seat of the front portion of sleeve pipe by the screw thread on the connecting rod, the tip of the front end of the screw thread on the connecting rod contacts with the afterbody galianconism that is fixed in the axle upper gripper jaw in the jaw seat respectively, has spring between jaw long-armed.

The beneficial effects of the utility model:

1, simple to operate:

When using extension clamp of the present utility model, with the rotation precession connecting rod of handwheel or screw out connecting rod, jaw is opened simultaneously or close, i.e. grip containers or decontrol container, operation extremely makes things convenient for, high efficiency;

2, rational in infrastructure:

Jaw of the present utility model is to be that the center is provided with the connecting rod in the sleeve pipe, and controls opening of jaw simultaneously or close with connecting rod, has just guaranteed the uniformity of the center of the container that is held with the center of connecting rod, has promptly guaranteed to be held the stability of container.

Description of drawings:

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

Fig. 2 is the structural representation of jaw and associated components.

The specific embodiment:

The utility model comprises sleeve pipe 12, the handwheel 14 at sleeve pipe 12 rear portions links to each other with the nut in the jaw seat 8 of the front portion of sleeve pipe 12 10 by the screw thread 9 on the connecting rod 11, and the tip 6 of the front end of the screw thread 9 on the connecting rod 11 contacts with the afterbody galianconism 7 of the jaw 2 on the axle 5 that is fixed in the jaw seat 8 respectively; Jaw 2 long-armed 4 between have spring 3.

For gripped object is had better neutrality, the clip 1 of long-armed 4 front ends is respectively triangle.

During making, jaw seat 8 can be welded in one with sleeve pipe 12; Handwheel 14 is fixed in one with connecting rod 11 with pin 13.

Below in conjunction with a description of drawings course of action of the present utility model:

When using the utility model extension clamp holding vessels, at first, container is placed the centre of the clip 1 of jaw 2, turn is in wheel 14, when connecting rod 11 is advanced, push the galianconism 7 of jaw 2 open the tip 6 of screw thread 9 front ends of connecting rod 11 to both sides, jaw 2 rotates around its axle 5, and jaw 2 overcomes the tension force move toward one another of the spring 3 on long-armed 4, produce and clamp action, container is clamped, fixes; When unclamping holding vessels, turn handwheel 14, connecting rod 11 is retreated, the tip 6 of screw thread 9 front ends of connecting rod 11 is no longer to galianconism 7 application of forces of jaw 2, and under the effect of spring 3, clip 1 opens thereupon, holding vessels no longer.

Claims

1, a kind of extension clamp comprises sleeve pipe (12), the handwheel (14) that it is characterized in that sleeve pipe (12) rear portion links to each other by the nut (10) in the jaw seat (8) of the front portion of the same sleeve pipe of screw thread (9) (12) on the connecting rod (11), and the tip (6) of the front end of the screw thread (9) on the connecting rod (11) contacts with the afterbody galianconism (7) of the jaw (2) on the axle (5) that is fixed in the jaw seat (8) respectively; Has spring (3) between long-armed (4) of jaw (2).

2, a kind of extension clamp according to claim 1 is characterized in that the clip (1) of long-armed (4) front end is respectively triangle.
