Embodiment Construction

[0158] In the preferred first embodiment of the power tool of the present invention, the power tool is a power screwdriver, which can be divided into pneumatic screwdrivers, hydraulic screwdrivers and electric screwdrivers according to different power sources, and electric screwdrivers are also divided into DC and AC. In this embodiment Take a DC electric screwdriver as an example for specific description.

[0159] refer to Figure 1 to Figure 3As shown, the DC electric screwdriver includes a casing 1 , a motor 2 , a battery 6 , a transmission mechanism 3 , a connector 51 , a working head support mechanism and an output shaft 4 . 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 operati...

Abstract

The invention relates to a power tool which comprises a machine casing, a motor, an output shaft, a transmission mechanism, a work head supporting mechanism and a connection part. The motor is arranged in the machine casing and outputs rotary power. The output shaft is provided with an axial accommodating hole used for accommodating work heads. The transmission mechanism transmits the rotary power output by the motor to the output shaft. The work head supporting mechanism is provided with a plurality of parallel accommodating spaces used for supporting the work heads. The connection part can penetrate through one accommodating space to lead the working position where the work heads accommodated in the accommodating space and the output shaft which are connected in matched mode and the release position separated from the accommodating space when the connection part exits from the accommodating space to move axially. An operation part for controlling the connection part to move axially is arranged on the machine casing. The power tool further comprises an automatic switching device used for responding to movement of the operation part and adjusting the position of the work head supporting mechanism. The connection part axially moves to be separated from one accommodating space, and the work head supporting mechanism moves to the position where anther accommodating space axially corresponds to the accommodating hole under the effect o the automatic switching device.

Description

technical field [0001] The invention relates to a power tool, in particular to a gun drill type power tool which can realize the storage and quick replacement of working heads. Background technique [0002] Existing gun drill power tools generally include electric drills, electric screwdrivers and impact drills. [0003] An electric screwdriver is a commonly used electric tool for tightening screws to 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, drilling, etc., when...
