[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a multifunctional hand-held angle grinder of the utility model comprises an angle grinder 1, a connecting rod 6 and a gripping rod 8, a ring body 2 is installed on one side surface of the angle grinder 1, and a plurality of positioning openings 3 are distributed in an annular structure on the outer side surface of the ring body 2, a limiting cavity is provided inside the angle grinder 1 at the center of the ring body 2, one end of the limiting cavity is provided with a through hole connected to the ring body 2, a limiting block 12 is provided in the limiting cavity, an axle rod 10 is installed at one end of the limiting block 12, the other end of the axle rod 10 extends through the through hole into the ring body 2, and a center block 4 is installed, a positioning rod 5 is installed on the outer ring surface of the center block 4, the positioning rod 5 passes through any one of the positioning openings 3 and is fixedly connected to the connecting rod 6, a connecting plate 7 is installed at the other end of the connecting rod 6 through a hinge, and the other end of the connecting plate 7 is fixedly connected to the gripping rod 8.

[0021] In this embodiment, the inner diameter of the through hole is smaller than the inner diameter of the limiting cavity, the diameter of the limiting block 12 is larger than the inner diameter of the through hole, and the diameter of the shaft 10 matches the inner diameter of the through hole, so that the limiting block cannot be moved out of the through hole, thereby limiting the connecting rod and the grip rod and preventing them from detaching from the angle grinder.

[0022] In this embodiment, a compression spring 11 is disposed inside the ring body 2 , and the compression spring 11 is sleeved on the outside of the shaft 10 . One end of the compression spring 11 is mounted on the angle grinder 1 , and the other end is mounted on the center block 4 .

[0023] In this embodiment, a C-type clamp 9 is installed on the outer wall surface of the angle grinder 1, and the grip rod 8 is clamped and fixed by the C-type clamp 9. The C-type clamp 9 is made of elastic plastic material. The grip rod can be fixed on the angle grinder through the C-type clamp so that the grip rod can be tightly attached to the angle grinder, reducing the volume and making it convenient to carry.

[0024] In this embodiment, the connecting plate 7 is eccentrically arranged so that after the connecting plate is rotated around the hinge, the inner side surface of the connecting plate can lean against the end surface of the connecting rod.

[0025] In this embodiment, the cross section of the positioning rod 5 is arranged in a rectangular structure, and the width of the positioning rod 5 matches the width of the positioning opening 3, so that the positioning rod can be stably inserted into the interior of the positioning opening.

[0026] In this embodiment, the diameter of the center block 4 matches the inner diameter of the center hole of the ring body 2, so that the center block fits the center hole of the ring body, avoiding the deviation of the center block.

[0027] When in use, first pull the gripping rod out of the C-shaped clamp, then pull the center block outwards through the gripping rod and the connecting rod, so that the center block drives the positioning rod to move out of the positioning port. After moving out, the center block can rotate around the limiting cavity and the through hole, so that the positioning rod can be rotated to the outside of any positioning port according to the habit of the staff, and the center block can be automatically pulled back into the inside of the ring body through the rebound of the compression spring, and the positioning rod is inserted into the corresponding positioning port. The positioning rod and the connecting rod can be positioned at different angles through the positioning port to adapt to the habits of different staff;

[0028] After the above positioning, the connecting plate can be rotated around the hinge so that the inner side of the connecting plate rests on the end face of the connecting rod, so that the grip rod and the connecting rod are arranged in an "L" shape, which facilitates the holding of the grip rod. The connecting rod can also keep the angle grinder away from the staff, avoiding discomfort caused by being too close.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
