TECHNICAL FIELD
[0001] The present application relates to the technical field of polishers, in particular to a polisher for polishing wall surfaces. BACKGROUND
[0002] Polishers are used to polish and polish the surface of an object, and the polishing object is generally a relatively hard object. In particular, there are wall polishers for polishing walls. The wall polisher includes a polisher body, a polishing disc, and a handle. The polisher body is provided with a motor and the like, and the motor is used to drive the polishing disc to polish the wall. The polisher body and the handle are also connected by a dust removal hose. The wall polisher needs to polish vertical walls and horizontal ceilings. In order to facilitate the user to adjust the polishing angle, the polisher body and the handle are hingedly connected in the existing wall polisher, so that the polisher body can rotate relative to the handle to facilitate the user to adjust the angle between the handle and the polisher body. When the user uses the wall polisher to polish the ceiling, the user needs to hold the polisher high and make the polishing disc adhere to the ceiling. However, since the polisher body is provided with a motor and the like, the weight of the polisher body is relatively large, and the polisher body and the handle are movably connected, so the polisher body is easy to swing and difficult to continuously adhere to the ceiling, which is a great test of the user's arm strength. Therefore, it is necessary to limit the movement of the polisher body when polishing the ceiling, and to prevent the polisher body from swinging as much as possible to assist the user. CONTENT OF THE UTILITY MODEL

When a user polishes a ceiling, the user can connect the movable end of the tension spring to the polishing machine body, so that the tension spring is in a stretched state, thereby limiting the swing of the polishing machine body. In this way, when the user polishes the ceiling, the polishing machine body is not easy to swing, and the user can more easily hold and operate the polishing machine to polish. When the user does not need to polish the ceiling, the tension spring can be accommodated in the accommodating groove of the mounting portion, that is, the tension spring is not exposed, so that the risk of injury caused by the tension spring is reduced, and the polishing machine is more beautiful.
[0006] Further, the polishing machine body is provided with a hook portion, and the other end of the tension spring is hooked to the hook portion.
[0007] Further, the accommodating groove is arranged on the top of the mounting portion and extends along the axial direction of the mounting portion.
[0008] Further, the mounting portion is a half shell, the mounting portion comprises an outer wall and an inner partition plate, two mounting portions are spliced into a cylindrical shape, the outer walls of the two mounting portions are spliced to form a top wall of the accommodating groove, and the inner partition plates of the two mounting portions are spliced to form a bottom wall of the accommodating groove.
[0009] Further, the polishing machine body comprises a pin shaft, the claw portion is rotatably connected to the pin shaft, so that the supporting arm can rotate relative to the polishing machine body.
[0010] Further, the polishing machine body comprises a polishing disc and a machine shell, a dust collection fan and a motor are accommodated in the machine shell, and an output shaft of the motor is perpendicular to the polishing disc.
[0011] Further, a dust discharge hose is additionally provided, one end of the dust discharge hose is connected to the polishing machine body, and the other end of the dust discharge hose is connected to the mounting portion of the supporting arm.
[0012] Compared with the prior art, the polishing machine has the beneficial effects that: the spring is arranged on the polishing machine, one end of the spring is fixed on the mounting portion of the supporting arm, and the other end of the spring is selectively connected to the polishing machine body. When the user polishes the ceiling, the movable connecting end of the spring is connected to the polishing machine body, so that the spring is in a stretched state, thereby limiting the swing of the polishing machine body. In this way, when the user polishes the ceiling, the polishing machine body is not easy to swing, the rotation amplitude of the polishing machine body is limited, and the user can more easily hold and operate the polishing machine to polish. When the user does not need to polish the ceiling, the spring can be accommodated in the accommodating groove of the mounting portion, that is, the spring is not exposed outside, so that the risk of the spring hurting people and the like is reduced, and the polishing machine becomes more beautiful.
