[0002] A planer is a tool used to plan and grind the surface to be processed, so as to achieve the purpose of flatness, dust-free, and protect the physical and mental health of workers, optimize the working environment, improve work efficiency, and enhance the quality of decoration. It can be used to process walls, floors, steps, and other surfaces.

[0003] The current planing and grinding machines use batteries or mains electricity as the energy source, and use motors to drive the grinding discs to rotate rapidly, thereby acting on the surface for planing and grinding. Among them, for environmental hygiene and to protect the health of users, a dust cover will be set on the machine head to prevent dust and impurities from spreading in the working space. The existence of the dust cover makes the size of the machine head larger, so that the surfaces to be processed, such as corners, corners of the ground, and the junction of two walls, cannot be polished well, and there are dead angles in use. These areas can only be polished by manual polishing, and the polishing effect is greatly reduced. Utility Model Content

[0018] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] This embodiment discloses a planer grinder. For the existing grinders with dust covers, the dust covers are larger than the grinding discs, which results in many dead angles that cannot be reached by the grinding discs. The grinder of the device is provided with a reversible dust cover, so that a part of the grinding disc is exposed to the outside, thereby achieving the effect of "bare disc" grinding and completely eliminating the dead angles.

[0020] like Figures 1 to 3 As shown, the planer grinder includes a housing 1 and a machine head 11 at the front end, and a grinding disc is installed under the machine head 11. A dust cover 2 is provided on the outer cover of the grinding disc. Among them, a folding portion 21 is movably provided on the dust cover 2. When grinding, the dust cover 2 can cover the dust raised by the grinding disc in the dustproof cavity surrounded by it. Then it is discharged through the suction pipe 3 connected above and through the vacuum cleaner. When it is necessary to grind a dead corner, the folding portion 21 is folded under the action of external force, so that the grinding disc in the dust cover 2 is partially exposed to grind the dead corner surface.

[0021] In order to adapt to the shape of the grinding disc, the dust cover 2 of the device is disc-shaped, or it can be square, and the square will take up more space. When it is disc-shaped, the folded portion 21 is the arcuate portion cut by the chord of the disc-shaped dust cover 2. If it is square, the folded portion 21 is rectangular. The difference in shape does not affect the function.

[0022] In addition, at least one circle of brushes 23 is arranged at the bottom of the dust cover 2 to separate the dustproof cavity surrounded by the dust cover 2 from the outside.

[0023] The folding part 21 is a part of the dust cover 2, which is installed together by rotating. The folding part 21 is rotatably arranged on the dust cover 2 by hinges; or another technical solution is adopted: the folding part 21 is provided with a rotating shaft at one end along the string, and a buckle or magnetic part is provided at the other end, so as to be connected with the dust cover 2.

[0024] In addition, the folding portion 21 can also be detachably connected by bolts, buckles or by buckles to the dust cover 2. When necessary, it can be directly disassembled.

[0025] The device is provided with a handle 4 on the machine head 11. When the grinding disc is grinding, vibration will be generated. If the grinding disc is held with one hand for a long time, the arm will become sore and unable to hold it tightly, which may cause accidents. The device can be held with both hands by providing a handle 4, and the position and posture of the grinding disc can be adjusted conveniently.

[0026] In addition, the device sets the switch of the grinder on the side wall of the front end of the housing 1, which is convenient for timely start and stop. A switch bracket is set on the side wall of the housing 1, and the switch 12 is set on the switch bracket. It is connected to the battery in the housing 1 through a lead wire, or connected to an external wire to realize power on and off control. A wind shield is set in the housing 1, and the wind shield is used to clamp the switch bracket on the housing 1 and place it off.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view. The scope of the present invention is defined by the appended claims, rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
