A conical tube 25 is fixedly connected to one end of the housing 1.

[0030] During specific implementation: by pressing the excitation handle 28 backward, the excitation handle 28 rotates and slides on the arc slide 29 through the rotating shaft 210, it is best to drive the pull rod 23 base 27 to move backward, and then drive the conical piston block 24 to move backward. The conical tube 25 helps to increase the pressure when spraying the colloid.

A front grip 31 is fixedly connected to the outer wall of the housing 1. A rubber delivery hose interface 32 is fixedly connected to one end of the outer wall of the housing 1.

[0032] During specific implementation: when the pull rod 23 moves backward, the cooperation of the spiral slide 34 and the auxiliary plate 33 will cause the pull rod 23 to rotate, and the pull rod 23 will also drive the conical piston block 24 to rotate, and then rub against the inner wall of the shell 1 to grind off some solidified materials, which helps to prevent blockage.
