[0016] The present application will be further described in detail in combination with the drawings. These drawings are all simplified schematic views, only schematically show the basic structure of the present application, and therefore only show the components related to the present application.

[0017] The full-automatic drilling sample avoids the loss of the sample to the largest extent, can realize the accurate control of the sampling amount of the sample, is obvious in advantages for some very precious and small-amount samples, the biological drilling chuck can automatically clamp and disassemble the drill rod, so that the whole experiment process does not need manual intervention, and even the experiment environment can be controlled as vacuum, the above sample pollution risk is avoided, and the biological sample collection efficiency is improved.

[0018] Please refer to Figure 1 The present application provides a biological positioning and quantitative automatic drilling chuck, which comprises a drill rod 1, a taper clamp 2, a locking sleeve group 3 and a positioning shaft 4. The non-rotary end of the drill rod 1 is inserted into the taper clamp 2, the drill rod 1 is used for sampling, the end of the taper clamp 2 away from the drill rod 1 is inserted into the locking sleeve group 3, the locking sleeve group 3 can automatically rotate, the locking sleeve group 3 drives the taper clamp 2 to be tightened or loosened through forward rotation or reverse rotation, the taper clamp 2 clamps and fixes the drill rod 1, the end of the positioning shaft 4 is fixedly installed in the locking sleeve group 3, the end of the positioning shaft 4 towards the locking sleeve group 3 is fixedly installed on the end of the locking sleeve group 3 away from the drill rod 1, and the positioning shaft 4 is used for being installed in a rotatable device.

[0019] Specifically, the taper chuck 2 is a three-jaw chuck, and when the taper chuck 2 moves inward or outward, the center of the drill rod 1 can be automatically found and clamped, the concentricity during sampling is ensured, and the end head of the drill rod 1 is prevented from swinging during sampling; the positioning shaft 4 is provided with a positioning groove at an end away from the locking sleeve set 3, and the positioning groove of the positioning shaft 4 is convenient to install in a rotating device.
