[0008] Preferably, the inner surfaces of the two groups of magnet blocks are both arranged to fit the outer surface of the handheld part and are fixedly arranged by being adsorbed on each other.
[0009] Preferably, the arc groove is arranged below the transmission shaft.
[0010] Preferably, the baffle is arranged on the inner side of the grinding disc.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] By installing the sleeve, slider, heat insulation plate, mounting block, screw, magnet block, extension plate, baffle, arc groove and other components, the problem that the existing hand-held grinder has no corresponding heat insulation operation can be effectively solved. In actual use, the user will directly hold the handheld part of the hand-held grinder, and the motor in the hand-held grinder will generate a lot of heat during use, which will inevitably cause burns to the user's hands.
[0013] The hands of the user will be separated from the motor by the installation sleeve and two sets of heat insulation plates, thereby preventing the motor from generating a large amount of heat during use, which may cause burns to the hands of the user. The baffle and the arc groove can separate the hands of the user from the grinding disc, thereby preventing sparks generated by grinding the grinding disc from contacting the hands of the user and causing burns.

[0017] 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.
[0018] according to Figure 1-Figure 2 As shown in the figure, it includes a hand-held part 1, and the outer surface of the hand-held part 1 is provided with slide grooves 11 on both sides, and a motor 12 is installed on the top of the hand-held part 1, one end of the two sets of slide grooves 11 are both open, and the output end of the motor 12 is connected to the grinding disc 13 through a transmission shaft.
[0019] Slide blocks 21 are slidably arranged inside the two groups of slide grooves 11, and one ends of the two groups of slide blocks 21 are installed on the inner wall of the mounting sleeve 2. Heat insulation plates 22 are installed on the left and right sides of the side surface of the mounting sleeve 2, and an extension plate 26 is installed on the end of the heat insulation plate 22 on the left side, and a baffle 27 is installed on the top of the extension plate 26, and an arc groove 28 is opened on the top surface of the baffle 27. The baffle 27 is arranged on the inner side of the grinding disc 13, and the arc groove 28 is arranged below the transmission shaft. Mounting blocks 23 are installed on the front and rear sides of the mounting sleeve 2, and screws 24 are movably screwed inside the two groups of mounting blocks 23. One ends of the two groups of screws 24 are installed on the outer surface of the magnet block 25 through bearings, and the inner surfaces of the two groups of magnet blocks 25 are fitted with the outer surface of the handheld part 1 and are fixed by mutual adsorption.
[0020] The user can first align the two sets of sliders 21 with the inside of the corresponding slide grooves 11 and move them upward, so that the installation sleeve 2 can move upward accordingly. When the top surfaces of the two sets of sliders 21 are respectively in contact with the top inner walls of the corresponding slide grooves 11, the installation sleeve 2 can be stopped from moving upward. After that, the user can rotate the two sets of screws 24 accordingly, so that the two sets of magnet blocks 25 can be moved to the corresponding side accordingly, so that the inner walls of the two sets of magnet blocks 25 can finally be in contact with the outer surface of the handheld part 1 and be adsorbed and fixed accordingly. At this time, the installation sleeve 2 and the handheld part 1 can be installed. At this time, the baffle 27 will be located on the inner side of the grinding disc 13, and the arc groove 28 will be located below the transmission shaft, so that The user can start the motor 12 first, so that the grinding disc 13 can be rotated through the transmission shaft under the operation of the motor 12.
