[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 4 A multifunctional AC angle grinder comprises an angle grinder body 1, wherein the angle grinder body 1 is provided with a handle 2, and the handle 2 is used for supporting force.

[0017] In order to adapt to the use in different directions or when people are used to using different hands, mounting holes 3 are provided on both sides of the main body 1, and the handles 2 can be installed in the mounting holes 3. In the prior art, the handles 2 are mostly installed into the mounting holes 3 by threaded connection. During use, the handles 2 will gradually become loose and cannot be detected, which poses a safety hazard. At the same time, the threaded rotation installation method is more troublesome.

[0018] Therefore, a plurality of first inclined blocks 4 are arranged in the mounting hole 3. The first inclined blocks 4 are embedded in the mounting hole 3 through the first spring 5, and the first inclined blocks 4 slide in the mounting hole 3. The two inclined surfaces of the first inclined blocks 4 are arranged toward the outside of the mounting hole 3, and cooperate with the handle 2 to achieve fast, firm and flexible installation.

[0019] The handle 2 includes a sliding part 6 and a control part 7, wherein the sliding part 6 has a larger diameter than the control part 7 and is located at the front end of the handle 2. The sliding part 6 matches the mounting hole 3. When the sliding part 6 moves between the first inclined blocks 4, the first inclined blocks 4 overcome the first spring 5 and retract into the mounting hole 3, and the sliding part 6 can move freely.

[0020] The opposite side of the inclined surface of the first inclined block 4 is a vertical surface, so the sliding member can be locked, that is, the first inclined block 4 is locked in the mounting hole 3, which can support the angle grinder and facilitate operation. The sliding portion 6 can be tightly embedded in the specific area formed by the inclined block in the mounting hole 3 of the main body 1, and has a locking function, ensuring that it is stable during work and easy to adjust the position according to different operating postures.

[0021] In order to unlock the first inclined block 4, the control part 7 has several second inclined blocks 8 built in. The second inclined blocks 8 slide at the end of the sliding control part 7. The second inclined blocks 8 have limited movement in the control part 7, that is, the second inclined blocks 8 have limited upward and downward movement. The above problems can be solved by installing a limit block on the second limit block or connecting the second inclined blocks 8 with elastic ropes.

[0022] A pull rod 9 is disposed in the center of the control portion 7. When the operator pushes the pull rod 9, the pull rod 9 acts on the second inclined block 8, and the second inclined block 8 moves outwards and presses against the first inclined block 4, so that the handle 2 can be taken out.

[0023] The pull rod 9 is connected to the bottom of the control part 7 via a second spring 10. When the second spring 10 is not acted upon by an external force, the pull rod 9 will not contact the second inclined block 8, so that the two will not affect each other, thereby avoiding accidental contact during operation.

[0024] Furthermore, pulling is more difficult to trigger than pushing, therefore, the other end of the pull rod 9 that is not a spring is connected to a pull rope 12, and two sets of through holes are arranged in parallel at the end of the control part 7. The pull rope 12 passes through the control part 7 through the first through hole, rotates 180 degrees, passes through the other through hole, and passes through the second spring 10 and the outside of the handle 2. A cap 11 is arranged at the end of the handle 2. The cap 11 is in the groove of the handle 2. When the cap 11 is pulled, the pull rod 9 moves toward the second inclined block 8 under the reaction force, that is, the second inclined block 8 squeezes the first inclined block 4, so that the handle 2 can be separated from the mounting hole 3.

[0025] Furthermore, an electromagnet 13 assembly is added inside the mounting hole 3 and is electrically connected to the angle grinder body 1. This design enables the sliding portion 6 to be made of a magnetic adsorption material or a covering layer, and after power is turned on, the handle 2 is fixed on the electromagnet 13, thereby enhancing the fixing effect of the handle 2.

[0026] 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.
