Detailed Description

The utility model is described in detail below with reference to the accompanying drawings:

in the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "top", "bottom", "upper", "lower", "left", "right", and the like are based on the directions or positional relationships shown in the drawings, or the directions or positional relationships which are usually placed when the products of the present invention are used, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or the element to be referred to must have a specific direction, a specific direction configuration and operation, and thus, the present invention is not to be construed as being limited.

As shown in fig. 1-2, the PCR eight-row tube single-row tube capping device comprises a base 1, a row tube placing groove 2, a roller capping device 3, a notch 4, a sliding groove 5 and an anti-skid pad 6, wherein the base 1 is inverted T-shaped, is narrow at the top and wide at the bottom, and is provided with the anti-skid pad 6 at the bottom surface to increase the static friction force between the bottom surface and an experimental table top. An eight-row pipe placing groove 2 is transversely arranged at the central position of the top surface of the base 1. The eight-row pipe placing groove 2 comprises a groove and 8 PCR pipe holes, and the 8 PCR pipe holes are positioned in the middle of the groove. The PCR tube hole can be designed into a through hole, so that the phenomenon that the eight-connected-row tube cannot be placed at the same height to influence the sealing effect of the gland due to the fact that falling foreign matters are deposited at the bottom of the tube is avoided. 8 PCR tube holes correspond 8 PCR tubes on the eight-linked calandria respectively, cover eight-linked calandria pipe lid back, and the upper surface of pipe lid is less than the top surface of base 1, plays the limit for height effect to the pipe lid, also makes things convenient for subsequent roll extrusion closing cap.
