Pointing device and use method

The invention belongs to the technical field of building construction, and particularly relates to a pointing device which comprises a hopper, a limiting assembly and a vibrating assembly, a feeding port is formed in one end of the hopper, a discharging port is formed in the other end of the hopper, the discharging port is aligned to a pointing joint, and the vibrating assembly penetrates through the discharging port and then is inserted into the pointing joint. The hopper is connected with the curbstone through the limiting assembly, and a groove is defined by the pointing joint through a part of structure of the limiting assembly and the curbstone. The device has the beneficial effects that the hopper is fixed to the upper portion of the pointing seam through the limiting assembly, the pointing seam is wrapped, a discharging opening of the hopper is aligned with the pointing seam, mortar can be prevented from polluting the surface of the curbstone to the maximum extent, meanwhile, the mortar is effectively
