The specific embodiment

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1 to Figure 3, a kind of clamping device of use for laboratory instrument, be used for clamping the laboratory apparatus such as flask, beaker, test tube, comprise base 10 and be vertically set on the pole 20 on base 10, pole 20 is provided with Height Adjustable flask holder 30 and test tube clamp 40, the circle footpath size of flask holder 30 is adjustable, and the openings of sizes of test tube clamp 40 is adjustable, and the support bar 50 that flask holder 30 and test tube clamp 40 are movably arranged on pole 20 by connection respectively regulates height along pole 20.

Concrete, flask holder 30 comprises and is mutually socketed into the first bow 31, the second bow 32 and the 3rd bow 33 that annular radian equates, the first bow 31 and the second bow 32 are two, two first bows 31 are socketed on respectively in the second bow 32, and two second bows 32 are socketed respectively the two ends of the 3rd bow 33.The second bow 32 is fixed on support bar 50, by adjust the first bow 31 and or the 3rd bow 33 be inserted in the circle footpath that the interior degree of depth of the second bow 32 is adjusted flask holder 30, simple in structure, operate more convenient.
