At this time, the spring 51 resets, and the test tube 4 is separated from the test tube cap 40. The control unit controls the electric telescopic cylinder to contract, and the staff takes the test tube 4, solving the technical problem that hand tremors in the prior art will cause the position of the test tube 4 to be inaccurate, thereby affecting the screwing effect of the test tube cap 40. Anti-slip patterns are provided at the bottom of the support base 12, improving the overall stability of the device.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
