Problems solved by technology
When the machine tool is working, the operating slider is offset against the tail of the tool chuck, the tool chuck rotates but the operating slider cannot rotate, so the sliding friction between the operating slider and the tool chuck is very large, which affects the work efficiency, while the tool wears out faster, reducing tool life

Embodiment Construction
[0079] In the preferred embodiment of the hand-held tool of the present invention, the hand-held tool is a hand-held multifunctional electric drill that can realize the functions of a drill and a screwdriver. There are also DC and AC in the electric drill. This embodiment preferably takes the DC multifunctional electric drill as an example. Be specific.
[0080] refer to figure 1 and figure 2 As shown, the DC multifunctional electric drill includes a casing 1, a motor 2, a battery 6, a transmission mechanism 3a, a connecting piece 51a, a working head support mechanism and an output shaft 4a. The casing 1 is composed of two symmetrical half shells assembled by screws (not shown). It has a horizontal part and a handle 11 part which is set at an obtuse angle with the horizontal part. The preferred angle of the present invention is 100 degrees to 130 degrees. Between degrees, it will be more comfortable when holding the handle 11 for operation. A button switch 7 is arranged on...

The invention relates to a handheld tool. The handheld tool comprises a case, an output shaft, a work head supporting mechanism and a connecting piece. The output shaft is supported on the case and provided with an accommodating hole arranged axially and used for accommodating a work head. At least part of the work head supporting mechanism is arranged in the case, the work head supporting mechanism is provided with a plurality of accommodating spaces arranged side and side and used for supporting the work head, and the work head supporting mechanism can be adjusted to the position where at least one accommodating space axially corresponds to the accommodating hole. The connecting piece is arranged in the case and is capable of driving the work head to be located in a work position in the accommodating hole or in an accommodating position of the work head supporting mechanism. One end, close to the output shaft, of the connecting piece is provided with a supporting device, and the supporting device can be in abutting joint with or be separated from the work head. The supporting device comprises a plurality of rolling pieces. When the supporting device is in abutting joint with the work head and is pressed by the work head, the rolling pieces can rotate relative to the connecting piece under the rotation effect of the work head.
Description
technical field [0001] The invention relates to a hand-held tool, in particular to a gun-drill hand-held tool which can realize the storage and quick replacement of working heads. Background technique [0002] Among the existing gun drill type hand-held tools, electric drills, screwdrivers, impact drills and the like are usually included. [0003] A screwdriver is a commonly used power tool for tightening screws onto workpieces. When screws with different specifications need to be tightened during use, different screwdriver bits should be replaced according to the different screw specifications, that is, the originally installed screwdriver bits should be removed, and then a screwdriver bit of another specification should be installed. [0004] The electric drill is used to drill holes on the workpiece. During the operation, the chuck clamps the drill bit and rotates continuously. [0005] Usually, users need to perform different types of operations, such as screwing, dril...
