[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1-8 As shown, a multi-functional angle grinder includes an angle grinder body 1. The rear end of the angle grinder body 1 is provided with a receiving component 2. The receiving component 2 includes a first receiving cavity 21 for accommodating a start switch, a second receiving cavity 22, a third receiving cavity 23, and a fifth receiving cavity 25 for accommodating a capacitor. A rotating shaft 3 is installed inside the receiving component 2.

[0030] In this embodiment, the first accommodating cavity 21, the second accommodating cavity 22, and the third accommodating cavity 23 used to accommodate the start switch have the same internal structure and are equipped with the same components. For example, a certain distance of space is reserved on the left and right sides of the first extension portion extending from the middle of the first accommodating cavity 21, the second accommodating cavity 22, and the third accommodating cavity 23. This reserved space is used to facilitate fixing the metal spring on the start switch from the left and right sides when the start switch is placed in the accommodating cavity. The metal spring is provided with through holes.

[0031] Each of the inner walls on the right side has a second extension portion extending outwards. When the start switch is placed in the receiving cavity, the second extension portion on the right side facilitates fixing the start switch. A semi-circular receiving hole is provided on the bottom wall. This receiving hole is used to fix the switch part at the rear end of the start switch when the start switch is placed in the receiving cavity.

[0032] The two square holes on the uppermost wall serve to facilitate the connection between the start switch and the capacitor when the start switch is placed inside the accommodating cavity. In other words, the connecting wires between the start switch and the capacitor are placed inside the two square holes.

[0033] The capacitor is placed in the fifth accommodating cavity 25 of the accommodating component 3. The fifth accommodating cavity 25 is located at the top of the accommodating component 3 and is in contact with the first accommodating cavity 21, the second accommodating cavity 22, the third accommodating cavity 23 and the fourth accommodating cavity 24.

[0034] The difference is that the accommodating area of ​​the first accommodating cavity 21 is larger than that of the second accommodating cavity 22, the accommodating area of ​​the second accommodating cavity 22 is larger than that of the third accommodating cavity 23. That is, the first accommodating cavity 21 can be used to place large-sized switches, the second accommodating cavity 22 can be used to place medium or medium-sized switches, and the third accommodating cavity 23 can be used to place small-sized switches.

[0035] Furthermore, the fourth accommodating cavity 24 provided in the accommodating component 2 is different from the first accommodating cavity 21, the second accommodating cavity 22 and the third accommodating cavity 23. The fourth accommodating cavity 24 is provided with a cable pressure plate 28 at the rear end. The cable pressure plate 28 is provided with fixing holes on the left and right sides, and a receiving hole for placing the power cord is provided in the middle position. The cavity inside the fourth accommodating cavity 24 is used to place the power line of the power cord. A square hole is provided on the uppermost wall of the cavity, which is used to facilitate the connection between the power cord and the capacitor. That is, the connection line between the power cord and the capacitor is placed in the square hole.

[0036] Furthermore, the fifth accommodating cavity 25 is also provided with symmetrically arranged support frames 27, which are used to support the capacitor. The support frames 27 have through second limiting holes 26 on the left and right side walls, and are hollow at the top and bottom. The support frame 27 also has a through hole at the center hole on the wall in front of the support frame 27, which is only for the rotating shaft 3 to pass through. The second limiting holes 26 are used to fit the limiting pin.

[0037] In this embodiment, the rotating shaft 3 is placed at the center hole of the receiving component 3, and the receiving component 3 is provided with a first connecting hole at this location. The rotating shaft 3 extends along the direction of the fifth receiving cavity 25 and is connected to the angle grinder body 1. The angle grinder body 1 is provided with a second connecting hole connected to the rotating shaft 3. The second connecting hole is placed at the center hole of the angle grinder body 1, and the center holes of the first connecting hole and the second connecting hole are aligned.

[0038] Furthermore, the rotating shaft 3 is provided with a first limiting hole 31, which is used to fit a limiting pin. The center of the first limiting hole 31 on the rotating shaft 3 is aligned with the center of the second limiting hole 26 on the fifth accommodating cavity 25.

[0039] When the limiting pin is placed in the first limiting hole 31 and the second limiting hole 32, the receiving component 3 cannot be rotated and is axially limited. It can only be rotated when the limiting pin is removed from the first limiting hole 31 and the second limiting hole 32.

[0040] In addition, the housing 3 has a mounting hole at the bottom for connecting to the housing, and the switch has clear markings for starting and stopping.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
