[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the 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 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.

[0028] Reference Figure 1 , Figure 3 The utility model provides an embodiment: an angle grinder with high protection performance, including a body 10, the right side of the body 10 is fixedly connected to an organic shell 9, the bottom end of the shell 9 is fixedly connected to a connecting block 17, the bottom end of the connecting block 17 is fixedly connected to a protective shell 4, the inner wall of the protective shell 4 is fixedly connected to an electromagnet 8, the electromagnet 8 and the body 10 are electrically connected, when the body 10 is powered on, the electromagnet 8 will also generate electricity, the inner wall of the protective shell 4 is elastically connected to a protective sleeve 3 through a spring 23, and the protective shell 4 is connected through the spring. The protective shell 4 and the protective sleeve 3 are configured so that the protective sleeve 3 is fixed on the inner wall of the protective shell 4. The outer wall of the protective shell 4 is provided with a clamping block 7. The outer wall of the protective sleeve 3 is provided with a groove 6. The clamping block 7 of the protective shell 4 is used to clamp the groove 6 on the protective sleeve 3 to stabilize it. The top of the protective sleeve 3 is fixedly connected with an electromagnet 22. The opposite surfaces of the electromagnet 1 8 and the electromagnet 2 22 are opposite in polarity. When power is turned on, the electromagnet 1 8 and the electromagnet 2 22 are attracted to each other by their opposite polarities. The electromagnet 2 22 is used to utilize the mutual attraction of the electromagnet 1 8 to make the protective sleeve 3 slide upward.

[0029] Reference Figure 1 , Figure 4 A cylinder 27 is fixedly connected to the front surface of the housing 9, and a groove 28 is provided on the outer wall of the cylinder 27. The groove 28 is used for limiting. A round tube 26 is slidably connected to the inner side of the cylinder 27, so that the round tube 26 can slide to the left side of the cylinder 27. The round tube 26 is elastically connected to the inner side of the handle 1 through the spring 25. The spring 25 is stretched by the handle 1 to drive the round tube 26 to move to the left side of the cylinder 27, so that the round tube 26 is stuck in the groove 28 and reset and stabilized by the reaction force of the spring. The handle 1 slides on the outer wall of the cylinder 27.

[0030] Reference Figure 1 , Figure 2 The top of the protective shell 4 is fixedly connected with a round tube 15, the bottom of the round tube 15 is fixedly connected with a filter screen 16 for filtering and intercepting impurities for easy cleaning, the top of the round tube 15 is fixedly connected with a hose 14, the bottom end of the machine shell 9 is rotatably connected with a spiral rod 12, and the bottom end of the connecting block 17 is fixedly connected with a T-shaped tube 11.

[0031] Reference Figure 2 , Figure 3 The bottom end of the spiral rod 12 is provided with a thread 19, so that it is more stably connected to the grinding sheet 21. The outer wall of the spiral rod 12 is slidably connected with a rolling bearing 13. The outer wall of the spiral rod 12 is fixedly connected with a disc 18. The bottom end of the spiral rod 12 is threadedly connected with a thin disc 20, and the thin disc 20 is used to stabilize the grinding sheet 21. The outer wall of the spiral rod 12 is rotatably connected with the grinding sheet 21, and the bottom end of the grinding sheet 21 is rotatably connected with a screw 24. It is used to fix the grinding sheet 21 to make it stable for grinding.

[0032] Working principle: When in use, first check whether the various accessories of the device can be used normally. If they can be used normally, when the electromagnet 8 is energized, the suction force of the electromagnet 8 will suck the electromagnet 22 upward. When the electromagnet 22 moves upward, it drives the protective sleeve 3 to slide upward, squeezing the spring 23 between the protective sleeve 3 and the protective shell 4. When the power is off, the electromagnet 22 is separated from the electromagnet 8, and the reaction force of the spring 23 causes the protective sleeve 3 to slide slowly downward. When it slides to a certain position, the block 7 on the surface of the protective shell 4 will be stuck in the groove 6 on the surface of the protective sleeve 3, and the protective sleeve 3 stops sliding and is fixed, thereby protecting the blade and providing protection.

[0033] Pull the handle 1 forward, and the spring 25 in the handle 1 will separate the handle 1 from the cylinder 27. Then move the handle 1 to the left into the groove 28 on the left side of the cylinder 27, and the reaction force of the spring 25 will stabilize the handle 1 on the left side of the cylinder 27, so that the handle 1 can be stored in a small space and can be easily moved.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
