In summary, the capillary support transfer device can clamp the capillary support 100 by arranging the connecting piece and the linear motion mechanism; on the other hand, the movement of the capillary holder 100 and the operation of covering the end cap 103 of the capillary holder 100 can be realized.

EXAMPLE five
The fifth embodiment is an improvement on the fifth embodiment, technical contents disclosed in the fifth embodiment are not described repeatedly, and the contents disclosed in the fifth embodiment also belong to the contents disclosed in the fifth embodiment.
In connection with fig. 6, when the capillary tube holder 100 is clamped and the cap 103 is capped, the fixed cylinder 115 is subjected to a large force in the vertical direction, and once the self-locking force of the first motor 116 is insufficient to support the force, the fixed cylinder 115 may tilt, and in order to overcome such a problem, the capillary tube holder transfer device further includes a limiting member; when the clamping jaw 104 and the supporting plate 106 clamp the member to be clamped, the stop member can prevent the fixed cylinder 115 from rotating.
Specifically, the limiting member is a limiting pin 129; the limit pin 129 is disposed below the fixed cylinder 115, and a limit hole is formed in the fixed cylinder 115 at a position corresponding to the limit pin 129.
