[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: an angle-adjustable angle grinder protective cover, comprising:

[0006] An annular buckle, wherein a first protective cover is fixedly connected to the outside of the annular buckle, an annular groove is formed on the outside of the annular buckle, and a second protective cover is slidably connected to the inside of the annular groove;

[0007] A limit assembly, the limit assembly comprising an elastic telescopic rod fixedly connected to the first protective cover, a clamping block fixedly connected to the telescopic end of the elastic telescopic rod, and a handle fixedly connected to the side of the clamping block;

[0008] The cleaning assembly comprises a connecting block fixedly connected inside the first protective cover, a first cleaning rod fixedly connected to the bottom end of the connecting block, and a second cleaning rod fixedly connected outside the second protective cover.

[0009] As a further solution of the utility model: a plurality of slots are provided on the top of the second protective cover, and the bottom ends of the card blocks are slidably connected in the corresponding slots.

[0010] As a further solution of the utility model: a cross groove is provided on the top of the second protective cover, and the connecting block penetrates and is slidably connected in the cross groove.

[0011] As a further solution of the utility model: the first cleaning rod abuts against the inside of the second protective cover, and the second cleaning rod abuts against the inside of the first protective cover.

[0012] As a further solution of the utility model: the shape of the connecting block is a cross, and a circular groove is formed at the front end of the annular buckle.

[0013] As a further solution of the utility model: a fastening bolt is sleeved through the circular groove, and a nut is fixedly connected to the left side of the front end of the annular buckle.

[0014] As a further solution of the utility model: the fastening bolt is threadedly connected in the nut, and a push handle is provided on the top of the second protective cover.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] The angle-adjustable angle grinder protective cover is provided with a first protective cover, a second protective cover, an elastic telescopic rod, a clamping block and a connecting block. When the second protective cover is rotated, the second cleaning rod and the first cleaning rod can respectively and synchronously clean the inner walls of the first protective cover and the second protective cover. This avoids the situation in which, after use, the worker needs to use a cleaning tool to clean the protective cover separately because a lot of debris and dust often adhere to the inside of the protective cover. This reduces the work intensity of the worker and ensures the cleaning effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 The angle-adjustable angle grinder protective cover shown comprises:

[0026] An annular buckle 1, a first protective cover 2 is fixedly connected to the outside of the annular buckle 1, an annular groove 3 is provided on the outside of the annular buckle 1, and the annular groove 3 and the second protective cover 4 cooperate with each other to avoid the misalignment of the second protective cover 4 during rotation, thereby ensuring the stable rotation of the second protective cover 4, and the second protective cover 4 is slidably connected in the annular groove 3;

[0027] The limiting assembly includes an elastic telescopic rod 5 fixedly connected to the first protective cover 2, a clamping block 6 is fixedly connected to the telescopic end of the elastic telescopic rod 5, and a handle is fixedly connected to the side of the clamping block 6;

[0028] The cleaning assembly includes a connecting block 7 fixedly connected inside the first protective cover 2, a first cleaning rod 8 fixedly connected to the bottom end of the connecting block 7, and a second cleaning rod 9 fixedly connected outside the second protective cover 4.

[0029] A plurality of card slots 10 are provided on the top of the second protective cover 4. By providing the card slots 10, the card slots 10 cooperate with the card blocks 6 to conveniently limit the rotation angle of the second protective cover 4, thereby preventing the second protective cover 4 from being offset and ensuring the stable use of the second protective cover 4.

[0030] The bottom end of the clamping block 6 is slidably connected in the corresponding clamping slot 10, and a cross slot 11 is provided on the top of the second protective cover 4. By providing the cross slot 11, the cross slot 11 and the connection block 7 cooperate with each other to prevent the connection block 7 from falling when moving, thereby ensuring the stable movement of the cross block;

[0031] The connecting block 7 is slidably connected in the cross groove 11, the first cleaning rod 8 abuts against the second protective cover 4, and the second cleaning rod 9 abuts against the first protective cover 2. The shape of the connecting block 7 is a cross, and a circular groove 12 is provided at the front end of the annular buckle 1. A fastening bolt 13 is sleeved through the circular groove 12. By setting the fastening bolt 13, the fastening bolt 13 and the nut 14 cooperate with each other, so that the protective cover can be quickly installed outside the angle grinder, and it is convenient for the tooling personnel to use the device;

[0032] A nut 14 is fixedly connected to the left side of the front end of the annular buckle 1 , and the fastening bolt 13 is threadedly connected in the nut 14 . A push handle 15 is provided at the top end of the second protective cover 4 .

[0033] The working principle of the utility model is:
