[0024] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0025] [Example 1]

[0026] A rotating handle, such as Figure 1 , including a base 4, a core shaft 3 and a handle body 2, wherein the base 4 is a part of the power tool housing or is installed separately on the power tool.

[0027] The base 4 is provided with an axial hole 41, a positioning groove 43 and a connecting groove 42, wherein the connecting groove 42 is an arc groove, which is concentric with the axial hole 41, and two positioning grooves 43 are provided and are both connected to the connecting groove 42, and are respectively provided at both ends of the connecting groove 42, and the extension lines of the positioning grooves 43 pass through the center of the axial hole 41. The angle between the two positioning grooves 43 is generally less than ninety degrees, and one of the positioning grooves 43 corresponds to the vertical state of the handle body 2, and the other positioning groove 43 corresponds to the horizontal or nearly horizontal state of the handle body 2.

[0028] The core shaft 3 is installed through the shaft hole 41, and the handle body 2 includes a gripping portion 22 and a bracket portion 23. The cross-section of the gripping portion 22 is preferably circular. The bracket portion 23 is provided in two groups, which are respectively connected to the two end positions of the gripping portion 22. The bracket portion 23 is provided with a shaft mounting hole 25 for mounting the core shaft 3. The bracket portion 23 and the core shaft 3 are connected through an axial elastic circlip 1. The elastic circlip 1 is provided at both ends of the core shaft 3. The shaft mounting hole 25 is a long hole in which an elastomer 24 is provided. The bracket portion 23 is provided with a protrusion 21. When the protrusion 21 is in the positioning groove 43, the position locking effect of the handle body 2 is achieved.

[0029] Specifically, the protrusion 21 is a square-shaped step, and the positioning groove 43 matches the shape of the protrusion 21 , so that the protrusion 21 remains stable when located in the positioning groove 43 .

[0030] In other embodiments, the transition position between the positioning groove 43 and the connecting groove 42 may be configured as a bell-mouth shape to facilitate entry of the protrusion 21 .

[0031] like Figure 4 、 Figure 5, Figure 4 The middle is state 1. When the handle body 2 is in state 1, the protrusion 21 of the handle body 2 is located in the positioning groove 43 on the left side, and the handle body 2 cannot rotate and is in a stable state.

[0032] When adjustment is required, the elastic body 24 of the handle body 2 is compressed to a certain extent so that the protrusion 21 slides into the connecting groove 42 (arc groove). At this time, the handle body 2 can switch the angle at will. When the handle body 2 is rotated to the vertical state, the protrusion 21 slides into the right positioning groove 43. At this time, the elastic body 24 of the handle body 2 is in a free state, the handle body 2 cannot rotate, and is in a stable state.

[0033] Since the handle body 2 can switch its state, the tool can be used in some space-constrained areas and can also protect items such as batteries below. When the power tool needs to be lifted, the handle body 2 can be adjusted to a vertical or other posture that is conducive to lifting, thereby realizing the function of lifting objects.

[0034] Example 2, based on Example 1, Figure 3 , the base 4 is provided with a limited auxiliary surface 44, such as Figure 4 、 Figure 5 When the handle body 2 is locked in two state positions, the bracket portion 23 contacts the limiting auxiliary surface 44 and can share the force of the protrusion 21.

[0035] A tool, such as a magnetic drill, a drilling machine or other portable electric or fuel-driven tool, includes a rotating handle in any of the above embodiments, the rotating handle is preferably installed near important parts of the tool, such as a battery, a fuel tank, etc., and when the rotating handle is rotated Figure 4 When in the middle state, the battery and fuel tank below can be protected.

[0036] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations and modifications may be made to the embodiments of the present invention without departing from the principles described.
