barrel are of an integrated structure, but the
tail end of a mouse is positioned at the joint of the mounting plate and the transparent fixing
barrel during injection; the mouse is easily frightened to excrete in the device during injection, and the part is difficult to clean after injection is completed. A transparent fixing
barrel is mounted in the middle of one side of the mounting plate, a plugging mechanism is movably mounted in the transparent fixing barrel, locking hooks are symmetrically and fixedly arranged on the upper portion and the lower portion of the side, close to the mounting plate, of the transparent fixing barrel, and locking hook grooves are symmetrically formed in the mounting plate; the locking hook groove and the locking hook are correspondingly arranged, a sliding groove is formed in the front side of the transparent fixing barrel, a locking bolt groove is formed in the rear side of the transparent fixing barrel, and a mouse
tail through groove directly communicated with the edge is formed in the center of one side of the mounting plate.
