The grip 120 is circumferentially fixed to the grip 110 such that the grip 120 is not easily or rotatably movable relative to the grip 110. The grip portion 120 is capable of sliding along the axial direction relative to the shank 110, so that a user can move the grip portion 120 to different positions of the shank 110 according to actual needs, for example, the hand of the user is relatively large, and can move the grip portion 120 to a position close to the tool bit 200. The position-variable grip 120 allows the user to adjust to the position most suitable for his/her grip, as desired. The diameter of the shank 110 may be set smaller by finally rotating the tool bit 200 by the grip 120, and in the embodiment where the tool bit 200 is fixed to the shank 110, the effect of extending the distance from the tool bit 200 to the grip 120 may be achieved by moving the grip 120 upward. While the thinner shank 110 may be inserted into a smaller bore, thus corresponding to extending the tool bit 200 so that it may be used as a long bit tool.

The grip 110 or the cylindrical portion of the grip 110 is non-circular in cross-section (transverse to the axial direction of the grip 110) such that the grip 120 is not easily or rotatably movable relative to the grip 110. In the present embodiment, the implementation of the cross section is not limited, and it may be preferably polygonal, elliptical, wavy, petal-shaped, or the like. The grip 120 is fitted to the grip 110 or the outer circumferential surface of the cylindrical portion of the grip 110 so that the grip 120 is not obstructed by the grip 110 when it moves relative to the grip 110. Further, an outer surface of the grip 120 is provided with an anti-slip groove so that a user screws the grip 120.

It should be noted that, based on the technical solution that the grip portion 120 and the grip portion 110 can slide relatively along the axial direction, further, there is a technical problem of how to keep the grip portion 120 at the desired position after moving to the position.

To solve the above problems, the present application provides two preferred implementations.

Mode one.

Optionally, the grip 120 is provided as a soft material.

In this embodiment, the holding portion 120 is made of a soft material, so that a larger maximum static friction force can be generated between the holding portion 120 and the handle 110, and thus the holding portion 120 can be kept at the desired position after being moved to the desired position, and can be moved to a position which is fixed relative to the handle 110 in normal use only when a larger axial force is additionally applied.

And a second mode.

Optionally, the grip portion 120 includes an outer layer and an inner layer, and the inner layer of the grip portion 120 is made of a soft material.

In this embodiment, the inner layer of the grip portion 120 is made of a soft material, so that a large maximum static friction force can be generated between the grip portion 120 and the grip portion 110, and the grip portion 120 can be maintained at a desired position after being moved to the position. The outer layer of the holding portion 120 may be made of a hard material such as metal to obtain a better holding feeling.

It should be noted that, based on the technical scheme that the tool bit 200 is fixed to the shank 110, further, there is a technical problem how to fix the tool bit 200 to the shank 110. In order to solve the above problems, the present application provides a preferred implementation.

Referring to fig. 3, the shank 110 is configured in a cylindrical shape, a bit mounting portion 111 is provided at a lower end of the shank 110, and the bit 200 is fixed to the shank 110.

In this embodiment, the lower end of the shank 110 is provided with a bit mounting portion 111 so that the bit 200 can be fixed to the shank 110.

Further, the tool bit 200 is fixed to the lower end of the shank 110, which has a problem of how to prevent the grip 120 from sliding out of the lower end of the shank 110. In order to solve the above problems, the present application provides a preferred implementation.

Optionally, a stop portion is disposed at the lower end of the handle 110, and an outer side surface of the stop portion protrudes from an outer side surface of the handle 110 at least partially.

In this embodiment, the outer side surface of the stop portion protrudes at least partially from the outer side surface of the handle 110, so that when the grip portion 120 slides to the position of the stop portion, the grip portion 120 is blocked by the stop portion, so that the grip portion 120 cannot slide in the direction, thereby preventing the grip portion 120 from sliding out of the lower end of the handle 110. In addition, in the embodiment without the stop portion or the embodiment with the adjustable stop portion, the grip portion 120 may be integrally separated from the lower end of the handle 110, so as to facilitate replacement of the grip portion 120 with different sizes, so that the use habit of the user is more satisfied.

In addition to the above-described implementation, there are other implementations of the holding portion 120 that can be held in a desired position after the holding portion 120 is moved to the position. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, the present application provides a preferred implementation.

Optionally, the grip 120 is provided with a movable locking structure for locking the grip 120 to the grip 110 or releasing the grip 120 from the grip 110.

In this embodiment, the holding portion 120 is provided with a movable locking structure, so that the holding portion 120 can be locked to the handle 110, or released from the handle 110 to slide relative to the handle 110, so that the holding portion 120 can be kept at a desired position after being moved to the position.

In a specific scenario, when the user uses the handheld tool, the user needs to rotate the handheld tool while holding the handheld tool against the user. This method of operation is difficult and difficult for the user to perform, and thus requires a hand tool to perform the operation. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, the present application provides a preferred implementation.

Referring to fig. 1-2, an upper end of the handle 110 is provided with a supporting portion 112 capable of rotating relative to the handle 110.
