[0006] In the above scheme, preferably, a box body is arranged along the fracture, the box body rotates on the sleeve, and telescopic expansion blocks are arranged on both sides of the hoop body at the bottom of the box body.

[0007] In the above solution, preferably, an inclined surface is provided on the opposite side of the expansion block.

[0008] In the above solution, preferably, a slider is provided in the box body, and the slider cooperates with the inclined surface to make the expansion block act on the fracture.

[0009] In the above solution, preferably, slide grooves are provided on both sides of the box body, a control board is placed in the slide groove, and the control board is connected to the slider.

[0010] In the above solution, preferably, the control panel is placed on the upper side of the connecting rod.

[0011] In the above solution, preferably, a spring is provided between the box body and the control board therein.

[0012] The beneficial effect of the utility model is that the connecting rod can be quickly and conveniently locked on the connecting rod and the matching pipe sleeve to achieve the locking of the hoop body. At the same time, the sleeve can be rotated by coordinating with the spring, the control plate, and the support block. Generally, the hoop body can be rotated on the angle grinder, which is convenient for controlling its rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 5 A protective cover for an angle grinder 1 includes a protective cover body, wherein the body includes a cover body 2 and a hoop body 3, wherein the cover body 2 is used for protecting a grinding disc, and the hoop body 3 is used for fixing on the angle grinder 1. However, since the angle grinder 1 has different postures and different uses, the cover body 2 needs to be rotated on the protective cover to adapt to a suitable position for protection.

[0019] Specifically, the hoop body 3 is not a complete circle, and a break 4 is provided on it. Connecting rods 5 are provided on both sides of the break 4, and the connecting rods 5 ensure that the main body of the cover body 2 can be sleeved on the angle grinder 1. In addition, in order to enhance the stability of the connecting rod 5, two groups of reinforcing blocks 6 are provided at the break 4, and the reinforcing blocks 6 are provided with connecting rods 5, and the connecting rods 5 are provided with sleeves 7 in cooperation.

[0020] The sleeve 7 can cover the two groups of connecting rods 5. Furthermore, the sleeve 7 and the connecting rod 5 are locked by threads. By rotating the sleeve 7 on the two groups of connecting rods 5, the hoop body 3 can be locked on the angle grinder 1, so that the cover body 2 can be fixedly used for protection.

[0021] At the same time, to unlock the hoop body 3, the sleeve 7 needs to be separated from the connecting piece as a whole, and most of the protective covers have plastic supports and have a certain ductility. Therefore, a box body 8 is arranged inside the sleeve 7. The shape of the box body 8 is just stuck in the fracture 4, and the box body 8 can be rotatably connected in the sleeve 7, that is, the rotation of the sleeve 7 does not affect the box body 8.

[0022] A support block 9 is provided at the bottom of the box body 8. When no external force acts on the support block 9, the support block 9 is located in the box body 8. A slider 11 is provided in the box body 8. At the same time, a relative inclined surface 10 is provided on the support block 9 relative to the inside of the box body 8. When the slider 11 moves the support block 9, the support block 9 can have a tendency to move outward.

[0023] At the same time, slide grooves 12 are arranged on both sides of the box body 8, and a control plate 13 is arranged in the slide grooves 12. The control plate 13 is located above the connecting rod 5. A spring 14 is arranged between the control plate 13 and the box body 8, so that the control plate 13 always rests on the connecting rod 5. When the sleeve 7 moves toward the connecting rod 5, the control plate 13 is at the top of the sleeve 7, that is, the support block 9 has no external force acting on it.

[0024] At the same time, after the sleeve 7 moves, the control plate 13 moves downward under the action of the spring 14. Under the action of the spring 14, the expansion block 9 acts under the reinforcement block 6 and slightly expands it due to the elasticity of the plastic, so that the hoop body 3 can be rotated for easy adjustment.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
