The invention discloses a clamping device for a molecular biology test. The clamping device includes a clamping device body, the upper end of the clamping device body is provided with a metal tweezerhandle, a hanging hole opening groove is formed in the middle of the metal tweezer handle, and the lower end of the metal tweezer handle is connected with a tweezer clamping arm connecting hinge; manual telescopic adjusting boxes are provided with screw rods capable of movably moving, and the screw rods are connected with tweezer tip mechanisms by adjusting nuts; by rotating adjusting knobs of thescrew rods, sharp head tweezer tips and flat head tweezer tips of both sides of the tweezer tips can be freely moved in the manual telescopic adjusting boxes, therefore, when not in use, the tweezertips can be moved in the adjustable boxes to protect the tweezer tips from damage and contamination; and meanwhile movable connecting plates are movably connected with fixed bearing arms through firstlimiting bolts, therefore, the tweezer tips can be freely rotated, the clamping angle of the tweezer tips is controlled, and use is more convenient. According to the clamping device for the molecularbiology test, the structure is simple and practical, operation is convenient, and the use efficiency of the clamping device can be greatly increased.
Description
technical field [0001] The invention belongs to the technical field of test equipment, in particular to a clamping device for molecular biology tests. Background technique [0002] In molecular biology experiments, it is often necessary to use tweezers to pick up pretreated centrifuge tubes, strips, gels, NC membranes or PVDF membranes and other experimental supplies. According to different materials, use different tweezers, pointed or flat tweezers , while the structure of the existing clamping device is relatively fixed, and it cannot be adjusted for the corresponding angle, nor can it be adjusted for horizontal movement. At the same time, the tip of the tweezers is relatively sharp. The inability to do this caused a great deal of trouble for the experiment. Contents of the invention [0003] The object of the present invention is to provide a clamping device for molecular biology experiments in order to solve the above problems, which solves the current existing proble...
