In addition, the plurality of positioning grooves 2261 need not be arranged at equal intervals, for example, when the second positioning structure 226 is configured to include a plurality of positioning grooves 2261 at unequal intervals, one of the bolts 1152 for positioning in cooperation with the first positioning structure 115 can be selectively inserted into a different one of the positioning grooves 2261 by one of the bolts 1152, so that the second positioning structure 226 of the tool head 20 can be selectively engaged with the first positioning structure 115 at a plurality of different angular positions with respect to the linear axis CL as a rotation center, thereby achieving the positioning effect of changing the angle of the tool head 20 with respect to the machine body 10.

In this preferred embodiment, the pipe portion 2211 is provided with the plurality of pins of the first positioning structure, and the plurality of positioning grooves of the second positioning structure are formed on the surface of the base 111. Therefore, the positioning groove on the machine body can provide the plug pin insertion positioning of the opposite tool head, and as the first positioning structure and the second positioning structure can still be in concave-convex fit with a plurality of rotation angles, the positioning effect of fixing the tool head after the concave-convex fit with the machine body after the relative rotation angle can be achieved.
