To provide a device for filling joints with ready mixed cement, which can apply pressure on the ready mixed cement for pressing into the joints and can freely change the angle of pressing the ready mixed cement with high adaptability.
In a joint mortar injection device, a battery 3 and a screw 8 driven by a motor 5 are built in a case 6, and a case 15 is provided with a rotatable tip of a nozzle 13 and an inflow entrance 10 of ready mixed cement above the screw 8. Alternatively, a separate cylinder provided with a motor driving switch 2, a nozzle 13, and a grip part 1 is connected to a cylindrical case 15 provided with the screw 8, the inflow entrance 10, and the motor 5 through a flexible tube 16, so as to constitute a device which can perform joint mortar injection at a site remote from a ready mixed cement reservoir site 11. A motor case of a drill driver having a cylindrical outer surface with a male thread or ribs is screwed into the cylindrical case 15 with a threaded inner surface (female thread) at one end and a built-in coupling joint 24 connected to the screw 8, so as to constitute the joint mortar injection device.
