Abstract
The utility model discloses a test tube clamp which comprises a long handle and a short handle, wherein the long handle and the short handle are connected in a hinged mode through a spring, mutual corresponding clamping grooves are arranged in inner sides of the long handle and the short handle and close to the upper ends of the long handle and the short handle, and the clamping grooves are provided with elastic buffering cushions. An arched thumb groove is arranged close to the bottom end of the short handle on the short handle, and finger placing grooves are arranged at the lower end of the long handle side by side. According to the test tube clamp, the elastic buffering cushions can prevent a test tube from being broken caused by too big clamping force, anti-skidding grains arranged on the elastic buffering cushions can prevent the test tube from slipping, the arched thumb groove can prevent a thumb from sliding forward, and the finger placing grooves can prevent fingers from slipping. The test tube clamp is simple and reasonable in structural design and safe and reliable to use, and greatly reduces difficulty of operation.
Description
Technical field
The utility model belongs to the education experiment apparatus, is specifically related to a kind of test tube clamp.
Background technology
Biology teachers usually needs to carry out various experiments in the process of giving lessons understand the student and grasp biological knowledge, in the process of carrying out Bioexperiment, to need to use many experiment apparatuses, test tube clamp is exactly one of experiment apparatus of commonly using, and it mainly is for holding test tubes in order to invisible spectro material is heated.Existing test tube clamp is made of the long handle that is connected together by spring hinge and short handle, the inboard of long handle and short handle is provided with corresponding draw-in groove, hold long handle during use, use simultaneously the tail end of thumb press short handle, the end of long handle and short handle is opened, contact test tube in order to clamp test tube with draw-in groove, but existing draw-in groove surface is harder, hand opens the too small words of the application of force if spring force is excessive, test tube is easy to be caught broken, and not only the carrying out of impact experiment also easily hurts the operator, and when using test tube clamp, thumb will be placed on the tail end of short handle, and for unskilled operator, it is easy to thumb is delivered to the front end of short handle when operation, being easy to scald hand in the process of heating test-tube, be absolutely unsafe like this.The long handle surface of test tube clamp is more smooth now in addition, and hand easily skids under long-time the gripping, is not easy to operation.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of structural design advantages of simple, convenient operation, safe and reliable test tube clamp.
The purpose of this utility model is achieved in the following ways: this test tube clamp, comprise the long handle and the short handle that are connected together by spring hinge, long handle and short handle are provided with the draw-in groove of mutual correspondence near the inboard of upper end, described draw-in groove is provided with flexible cushion pad, described short handle is provided with the thumb grooves of arch near the bottom, the lower end of described long handle is provided with side by side puts the finger groove.
Described cushion pad, thumb grooves and put the surface that refers to groove and be equipped with anti-slip veins.
The beneficial effects of the utility model are: flexible cushion pad can prevent from being caught broken test tube because clamping force is excessive, and the anti-slip veins on it can be avoided the test tube slippage; The thumb grooves of arch can prevent forward slippage of thumb; Standing groove can prevent from pointing slippage.Its structural design advantages of simple, safe and reliable, greatly reduce the difficulty of operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, this test tube clamp, comprise the long handle 1 and the short handle 2 that are connected together by spring hinge, long handle 1 and short handle 2 are provided with the draw-in groove 3 of mutual correspondence near the inboard of upper end, described draw-in groove 3 is provided with flexible cushion pad 4, described short handle 2 is provided with the thumb grooves 5 of arch near the bottom, the lower end of described long handle 1 is provided with side by side to put and refers to groove 6.Cushion pad 4, thumb grooves 5 and put the surface that refers to groove 6 and be equipped with anti-slip veins.Elastic buffering pad 4 of the present utility model can prevent from being caught broken test tube because clamping force is excessive, and the anti-slip veins on it can be avoided the test tube slippage; The thumb grooves 5 of arch can prevent forward slippage of thumb; Standing groove 6 can prevent from pointing slippage.
