When the rotating disc 23 continuously drives the driving arm 24 to move in a circular manner, the pressurizing piston 25 at the other end of the driving arm 24 is pushed to move reciprocally. When the pressurizing piston 25 moves upward, the one-way valve on the air inlet 26 can guide the external air into the pressurizing box 22. When the pressurizing piston 25 continuously moves downward, the air pressure in the pressurizing box 22 can be guided from the air outlet 27 into the quantitative box 2, so that the mortar in the quantitative box 2 can be efficiently discharged from the grouting pipe, and the mortar can be effectively prevented from being blocked in the inner wall of the grouting pipe.
