the second motor 42 is arranged in the outer cylinder 2 and can drive the material storage cylinder 3 to rotate, so that the number and the on-off of the discharged materials are controlled. Aiming at different closures, the control of the discharging amount of the sealing grease can be realized by controlling the rotation angle of the material storage cylinder 3. The sealing block 45 is movably arranged on the storage cylinder 3 so as to keep the pressure inside the storage cylinder 3 constant.
