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.

[0022] See also Figure 1-Figure 4 The utility model discloses an angle grinder with multiple dust-proof mechanisms, including a handheld end 1, a head 2 is provided at the front end of the handheld end 1, a plurality of air inlets 3 are provided at the front of the head 2, air outlets 4 are provided at both sides of the handheld end 1, slide grooves 5 are provided at the upper and lower surfaces of the handheld end 1, auxiliary mechanisms are installed inside the two slide grooves 5, and the handheld end 1 is provided with a multifunctional handheld handle;

[0023] The multifunctional hand-held handle includes a pair of hand-held handle bodies 6, and a plurality of first vents 7 are provided on the sides of the two hand-held handle bodies 6 that are away from each other. A plurality of second vents 8 are provided on the upper and lower ends of the hand-held handle bodies 6, and two adjacent second vents 8 are merged into a third vent, wherein four third vents are inlaid with matching magnetic clips 9, with marks on the front and the front facing outward, which can play a fastening role. A first filter element 10 is provided at the rear end of the two hand-held handle bodies 6, which has a good dust-proof filtering effect on the air outlet 4, and a connecting card block 11 is provided at the front end of the two hand-held handle bodies 6. A second filter element 12 is provided at the front end of the two connecting card blocks 11, which has a good dust-proof filtering effect on the air inlet 3.

[0024] Specifically, the auxiliary mechanism includes a slide plate 13 slidably connected to the slide groove 5, a plurality of first magnet pieces 14 are inlaid and fixedly connected on the top surface of the slide plate 13, a plurality of second magnet pieces 15 are inlaid and fixedly connected on the top surface of the slide plate 13, a push piece 16 is provided on the top surface of the slide plate 13, a spring 17 is fixedly connected to the slide plate 13 and the rear inner wall of the slide groove 5, the second magnet piece 15 is located between the two first magnet pieces 14, and the installation direction of the second magnet piece 15 is opposite to that of the first magnet piece 14.

[0025] In this embodiment, during installation, the first magnet piece 14 and the magnet clamp 9 are attracted by opposite polarities, and the magnet clamp 9 is firmly clamped. During disassembly, the second magnet piece 15 and the magnet clamp 9 repel each other by the same polarity, and the magnet clamp 9 is easy to remove.

[0026] Specifically, first slots 18 are provided on both sides of the head 2 , and a second slot 19 is provided on the air outlet 4 .

[0027] In this embodiment, it plays a role of positioning and clamping, and can effectively improve the stability of the two handle bodies 6 after splicing.

[0028] Specifically, the handle body 6 is a shell structure, and the inner wall of the handle body 6 is spaced apart from the outer wall of the handheld end 1 .

[0029] In this embodiment, the ventilation effect is good, the heat conduction effect is poor, and the handle body 6 is not prone to heating up.

[0030] Specifically, both sides, the top surface and the front side of the head 2 are provided with threaded circular grooves 20 , and a gripping handle 21 is threadedly connected to the threaded circular grooves 20 .

[0031] In this embodiment, the position of the grip handle 21 can be flexibly adjusted according to the user's usage habits and usage requirements, thereby improving the working efficiency of the angle grinder. It also has the function of disassembly and assembly, does not increase the size of the angle grinder, and is easy to carry.

[0032] The working principle and use process of this utility model:

[0033] The steps of installing the multifunctional hand-held handle are as follows: dock the two hand-held handle bodies 6, and make the connecting block 11 snap onto the first slot 18. At this time, the second filter 12 fits on the head 2 and blocks the air inlet 3, so as to realize dust-proof filtration of the air inlet 3, and the first filter 10 snaps onto the second slot 19, so as to realize dust-proof filtration of the air outlet 4. The magnet clamp 9 (front side facing outward) is snapped onto the third vent. At this time, the magnet clamp 9 and the first magnet sheet 14 are oppositely attracted. At this time, when holding, the heat on the surface of the hand-held end 1 is not easily introduced into the surface of the hand-held handle body 6, and the friction resistance on the surface of the hand-held handle body 6 is large, so the holding is firm.

[0034] When the multifunctional hand-held handle needs to be removed, the sliding plate 13 is slid and the spring 17 elastically contracts. At this time, the second magnet sheet 15 is switched to contact with the magnet clamp 9. Since the magnet clamp 9 and the second magnet sheet 15 repel each other with the same polarity, a repulsive force is generated at this time, and the magnet clamp 9 is easy to take out from the third vent. At this time, the two combined hand-held handle bodies 6 lose their limit and are easy to disassemble.

[0035] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
