The dispensing structure of claim 1, characterized in that the dispensing structure further comprises: The three-way joint is arranged on the pump body and is provided with a first port, a second port and a third port which are mutually communicated, and the first port is in butt joint with the outlet of the pump cavity.
  9. 9. The dispensing structure of claim 8, characterized in that the dispensing structure further comprises: the first one-way valve is arranged on the three-way joint and is in butt joint with the second port, and is used for supplying semen to be input into the pump cavity in a one-way and/or, The second one-way valve is arranged on the three-way joint and is in butt joint with the third port, and the second one-way valve is used for one-way discharge of semen in the pump cavity.
  10. 10. An insemination gun comprising a dispensing structure as described in any of claims 1-9.

Description

Dispensing structure and insemination rifle Technical Field The application relates to the technical field of artificial insemination of domestic animals and birds, in particular to a delivery structure and an insemination gun. Background In the cultivation of poultry and livestock, the artificial insemination technology is adopted to improve the reproduction efficiency and genetic quality of the poultry and livestock. Artificial insemination operations (such as collection, dilution, preservation, transfer, insemination and other operations) are usually performed manually, and operators usually use a pipette during the semen transfer operation, so that the pipette is easy to wear during the use process, the efficiency of the artificial semen transfer operation is low, and the cost and the efficiency of large-scale cultivation are limited. Disclosure of utility model The present application aims to solve at least one of the technical problems existing in the prior art. Therefore, the main purpose of the application is to provide a delivery structure and a semen delivery gun, which aim to solve the problem of low semen transfer operation efficiency in artificial insemination of poultry and livestock. To achieve the above object, the present application provides a dispensing structure for an insemination gun for poultry or livestock, the dispensing structure comprising: The pump body is provided with a pump cavity for accommodating semen and an outlet communicated with the pump cavity; The first end of the piston rod is matched and slides in the pump cavity so as to suck or pump semen with preset volume through the outlet of the pump cavity; And the adjusting piece is arranged on the pump body or the piston rod and is used for adjusting the length of the sliding stroke of the piston rod in the pump cavity. Optionally, the piston rod has a second end protruding outside the pump body; the adjusting member includes: The first limiting block is connected with the second end, the relative distance between the first limiting block and the pump body is adjustable, and the first limiting block is driven by the piston rod to approach and abut against the pump body so as to limit the piston rod to continuously extend into the pump body. Optionally, the piston rod has a second end protruding outside the pump body; the adjusting member includes: The second limiting block is connected with the pump body, the relative distance between the second limiting block and the end part of the second end of the piston rod is adjustable, and when the second end of the piston rod moves in the direction away from the pump body, the end part of the second end of the piston rod is close to and abuts against the second limiting block.
