Inoculation needle

Abstract

The invention discloses an inoculation needle and belongs to a needle. The structure of the inoculation needle comprises a needle body and needle heads, wherein the needle body comprises a fixed needle body and moveable needle bodies; the fixed needle body is a cylinder; the upper ends of the moveable needle bodies are connected with the fixed needle body; the needle heads are arranged at the lower ends of the moveable needle bodies; three moveable needle bodies are uniformly arranged along the peripheral direction of the fixed needle body; each of the moveable needle bodies is arc-shaped and is gradually narrowed from top to bottom; a fastening bolt is arranged on the upper part of each of the moveable needle bodies; an external thread matched with an internal thread of the fastening bolt is arranged on the outer surface of the upper part of each of the moveable needle bodies; a positioning bolt is arranged in the middle of the fixed needle body; and the top and bottom of the positioning bolt respectively extend out of the fixed needle body. The inoculation needle has the characteristics that: a distance between the needle heads is adjusted according to the size of a bacterium sheet punched by a puncher so as to cause the size of the distance to be consistent with the size of the bacterium sheet; the depth of the needle heads inserted into cotton bolls can be adjusted, so that the damaged degree of the cotton bolls is uniform and consistent; and the inoculation effect error is small.

Description

technical field [0001] The invention relates to a needle body, in particular to an inoculation needle for inoculating fruits such as cotton bolls. Background technique [0002] Now when inoculating fruit such as cotton bolls, the cultured bacteria in the culture medium are punched with a puncher to make a plate, and then the plate is picked out and pasted on the cotton bolls that have damaged the epidermis for inoculation. When destroying the epidermis of cotton bolls, the epidermis of cotton bolls is usually needled manually, one needle, or multiple needles holding a thorn, but the distance between the needles cannot be adjusted, and it cannot be compared with the hole punched by the puncher. The size of the bacteria is the same, and the inoculation cannot be carried out well. In addition, the depth of the thorns is not easy to adjust through artificial thorns, and it is easy to cause human error in the test. At present, there is no good solution.
