As an optimal technical scheme of the utility model, the braking is the gear locking braking when being in on rack and the sawtooth simultaneously.
As an optimal technical scheme of the utility model, connecting axle and gear are the key-type connection, ensure that the connecting axle can drive gear revolve to gear and rack are connected for the meshing, ensure that the gear can go up and down on the rack.
As a preferred technical scheme of the utility model, the loose the modulus of gear (52) is 2, and the number of teeth is 20, and the tooth width is 16.
As a preferred technical scheme of the utility model, the modulus of sawtooth (51) is 2 on rack (3) and movable groove (5), and the tooth width is 16.
As an optimized technical scheme of the utility model, activity groove and draw runner are sliding connection, paint lubricating oil so that relative slip between the two during the use between the two.
As an optimized technical scheme of the utility model, the locating hole diameter is 0.7 centimetres, ensures that the test tube clamp can insert the hole.
The utility model has the advantages that: the fixed rod is easy to lift and adjust the height, so that the problem that the traditional device is inconvenient to adjust is solved; meanwhile, a self-locking fixing structure is designed, so that the movable groove is braked while the test tube clamp is firmly fixed; when the height of the test tube clamp is adjusted and fixed, only the knob needs to be rotated and translated, so that the test tube clamp is simple and labor-saving; the device is convenient to use, high in practicability and suitable for large-scale popularization and use.
