[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-2 A grinding device for the corner of a metal part includes an adjustable telescopic rod 3. One end of the adjustable telescopic rod 3 is rotatably connected to a first support plate 9 and a second support plate 11 symmetrically arranged in a V-shape. The other end of the adjustable telescopic rod 3 is rotatably connected to a support roller 2. An annular grinding belt 15 is wrapped between the support roller 2 and the first support plate 9 and the second support plate 11. The support roller 2 is driven by a rotary power source. An adjustment mechanism is connected between the first support plate 9, the second support plate 11 and the adjustable telescopic rod 3. The adjustment mechanism can adjust the opening angle between the first support plate 9 and the second support plate 11.

[0019] When this device is working, the opening and closing angle between the first support plate 9 and the second support plate 11 is adjusted according to the angle of the workpiece by the adjustment mechanism, so that the first support plate 9 and the second support plate 11 are attached to the two grinding surfaces of the workpiece. Then, the rotary power source is started, which drives the support roller 2 to rotate, and the support roller 2 drives the grinding belt 15 to rotate, so as to realize the grinding work at the angle position. This device can freely adjust the opening and closing angle between the first support plate 9 and the second support plate 11 according to actual needs, so as to realize the grinding operation of different workpiece angles. It is highly adaptable and easy to use.

[0020] refer to Figure 1 , Figure 2 In one embodiment, the adjustment mechanism includes a sliding sleeve 5 that is slidably connected to the adjustable telescopic rod 3. The sliding sleeve 5 is fixed to the adjustable telescopic rod 3 by a first locking bolt 4. One side of the sliding sleeve 5 is rotatably connected to a first support rod 7 by a first hinge 6. The first support rod 7 is rotatably connected to a first support plate 9 by a second hinge 8. The other side of the sliding sleeve 5 is rotatably connected to a second support rod 13 by a fourth hinge 14. The second support rod 13 is rotatably connected to a second support plate 11 by a third hinge 12.

[0021] By changing the support angle of the first support rod 7 and the second support rod 13 on the first support plate 9 and the second support plate 11 through the sliding sleeve 5, the opening and closing angle of the first support plate 9 and the second support plate 11 can be adjusted. The structure is simple and the adjustment is convenient.

[0022] The adjustable telescopic rod 3 includes a first rod 18 and a second rod 21 that are slidably connected. The first rod 18 and the second rod 21 are locked by a second locking bolt 19. The sliding sleeve 5 is slidably connected to the first rod 18. The first support plate 9 and the second support plate 11 are rotatably connected to the end of the first rod 18 away from the second rod 21. The support roller 2 is rotatably connected to the end of the second rod 21 away from the first rod 18.

[0023] refer to Figure 1 When the sliding sleeve 5 is slid to the left, the opening angle of the first support plate 9 and the second support plate 11 increases, and at the same time the first rod 18 and the second rod 21 retract to adapt to the change in shape of the sanding belt 15.

[0024] Further reference Figure 1 A thrust spring 20 is installed between the first rod 18 and the second rod 21. Loosen the second locking bolt 19 so that the support roller 2 end of the adjustable telescopic rod 3 is in an elastic telescopic state. Then adjust the position of the sliding sleeve 5. After the opening and closing angles of the first support plate 9 and the second support plate 11 are adjusted, lock the first locking bolt 4 and the second locking bolt 19. Adjusting using the elasticity of the thrust spring 20 makes it simpler.

[0025] As one embodiment where the first support plate 9, the second support plate 11, and the adjustable telescopic rod 3 are rotatably connected, see reference. Figure 2 An adjustable telescopic rod 3 has a support column 10 fixedly connected to one end. The first support plate 9 includes a first cylindrical portion 16 and a first plate body 23. The first cylindrical portion 16 is fixedly connected to or integrally formed at one end of the first plate body 23, and the first cylindrical portion 16 is rotatably connected to the support column 10. The second support plate 11 includes a second cylindrical portion 17 and a second plate body 22. The second cylindrical portion 17 is fixedly connected to or integrally formed at one end of the second plate body 22, and the second cylindrical portion 17 is rotatably connected to the support column 10. The first plate body 23, the second plate body 22, and the support column 10 are rotatably connected through the first cylindrical portion 16 and the second cylindrical portion 17.

[0026] In order to enable the support roller 2 to drive the grinding belt 15 to rotate better, the first support plate 9 and the second support plate 11 are both stainless steel plates or plastic plates with smooth surfaces and low friction. The outer circumference of the support roller 2 has a friction part that can increase the friction between the support roller 2 and the grinding belt 15, resulting in high friction.

[0027] One end of the support roller 2 is coaxially fixed to a connecting part 1. The connecting part 1 can drive a rotating power source. For example, the connecting part 1 has a hexagonal hole. By installing a hexagonal column on an electric drill and inserting the hexagonal column into the connecting part 1, the device can be driven to run by the electric drill.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
