Floor laying auxiliary device capable of solving problems of inconsistent knocking force and loud noise

The invention relates to the technical field of decoration floors, and discloses a floor laying auxiliary device capable of solving the problems of inconsistent knocking force and loud noise. Through the cooperative use of a second disc, a limiting plate, a push rod and a balancing weight, when floors are laid, the joints of the floors can be automatically knocked with the same force, so that the situation that a hammer needs to be manually used for beating when the floors are laid is avoided, time and labor are saved, meanwhile, uniform stress is guaranteed, and damage to the floors due to overexertion is avoided; through the cooperative use of a resistive silencer, an oil storage chamber, a baffle, an oil outlet and a special-shaped disc, during beating, lubricating liquid automatically overflows for lubrication, so that resistance is reduced, meanwhile, noise generated in the operation process of the device is reduced, and the purpose of reducing the noise is achieved; and through the use of a gradienter, when the floors are laid, bubbles carried by the gradienter are used for detecting or measuring the overall levelness of the installed floors, so that the situation that the levelness of the floors is consistent is guaranteed, and the attractiveness is improved.
