When building a house, it is inevitable to paint the walls. After the wall is painted, the base surface needs to be leveled and the wall surface needs to be polished. Most of the existing polishing tools are wall grinders, which use motors to drive the leveling grinding wheel to grind the wall surface. Most of the existing wall grinders are equipped with a single leveling grinding wheel. When grinding the internal angle position, it is necessary to grind twice to grind both sides of the internal angle, and the two walls after grinding cannot be guaranteed to be vertical.

[0013] See attached Figure 1-3The embodiment of the present invention discloses a wall leveling device, which is applied to a wall at a concave angle position, and includes a shell 2, a driving motor 22 and two leveling grinding wheels 1. The shell 2 is a hollow structure, and the driving motor 22 is arranged in the shell 2. The front ends of the two leveling grinding wheels 1 are respectively abutted against the vertical walls at the two concave angle positions, and the rear ends of the two leveling grinding wheels 1 are respectively coaxially connected with rotating rods 3, and the two rotating rods 3 are axially vertically arranged. Through holes are opened on the two vertical surfaces of the shell 2, and bearings are fixed at the positions of the through holes. The rear ends of the two rotating rods 3 are fixedly inserted in the inner rings of the bearings, and the rear ends of the two rotating rods 3 extend into the shell 2 through the through holes; a transmission assembly is arranged in the shell 2, and the driving end of the transmission assembly is connected to the output shaft of the driving motor 22, and the output end of the transmission assembly is connected to the two rotating rods 3. The two rotating rods 3 are driven to rotate synchronously perpendicular to each other through the driving motor 22 and the transmission assembly, so as to drive the two leveling grinding wheels 1 to rotate synchronously.

[0014] In this embodiment, the transmission assembly includes a main bevel gear 5 and a slave bevel gear 4, which are vertically meshed and transmitted. The main bevel gear 5 is fixedly sleeved on the output shaft of the driving motor 22, and the front end of the main bevel gear 5 is coaxially fixed with one rotating rod 3, and the front end of the slave bevel gear 4 is coaxially fixed with the other rotating rod 3. The main bevel gear 5 is driven to rotate by the output shaft of the driving motor 22, and the main bevel gear 5 synchronously drives the slave bevel gear 4 vertically meshed with it to rotate, and the main bevel gear 5 and the slave bevel gear 4 respectively drive the two rotating rods 3 to rotate synchronously, thereby driving the two leveling grinding wheels 1 to rotate vertically and synchronously.

Through holes are opened on the upper ends of the two limit plates 6. Bearings are fixed in the through holes. The two rotating rods 3 in the housing 2 are respectively fixedly inserted in the inner rings of the two bearings, so that the upper ends of the two limit plates 6 are respectively movably sleeved on the two rotating rods 3 inside the housing 2. When the driving motor 22 drives the main bevel gear 5 and the slave bevel gear 4 to rotate, the limit plates 6 and the bearings increase the stability of the two rotating rods 3 driven by the driving motor 22 to rotate.
