Embodiment Construction

[0067] In a preferred embodiment of the power tool of the present invention, the power tool is a power screwdriver, which can be divided into a pneumatic screwdriver, a hydraulic screwdriver and an electric screwdriver according to the power source, and there are also DC and AC in the electric screwdriver. Take a moving screwdriver as an example for specific description.

[0068] refer to Figure 1 to Figure 3 As shown, the DC electric screwdriver includes a casing 1 , a motor 2 , a battery 6 , a transmission mechanism 3 , a working head quick change mechanism 5 and an output shaft 4 . The casing 1 is composed of two left-right symmetrical half-shells assembled by screws (not shown), which has a horizontal part and a handle 11 part arranged at an angle K with the horizontal part. The preferred angle K of the present invention is 100 degrees Between to 130 degrees, it will be more comfortable when holding the handle 11 for operation like this. A button switch 7 is arranged on...

Abstract

The invention relates to a power tool. The power tool comprises an enclosure, a motor, a main shaft, a transmission mechanism and a storage clamp, wherein the motor is arranged in the enclosure and outputs rotation power, the main shaft is connected with one of a plurality of work heads in a matched mode and used for driving the one of the plurality of work heads to rotate, the transmission mechanism is arranged between the motor and the main shaft and can transmit the rotation power output by the motor to the main shaft, the storage clamp is partially contained in the enclosure and comprises containing bins used for containing the plurality of working heads arranged in parallel, the main shaft can move in the axial direction between the working position where the main shaft is connected with the one of the plurality of work heads in the matching mode after passing one of the containing bins and the releasing position where the main shaft is separated from the one of the plurality of work heads, the enclosure is provided with an open part, and when the main shaft is located in the releasing position, the storage clamp can be removed from the enclosure through the open part. The storage clamp of the power tool can be removed from the enclosure directly without the help of other tools, the operation is simple, and the working efficiency is high.

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 working heads, that is, batch heads, should be replaced according to different screw specifications, that is, the originally installed working head should be removed, and then a working head with another structure should be installed. . In the occasions where the working head needs to be replaced frequently, it brings great inconvenience to the operator. On the one hand, it is cumbersome to replace the working head, and on the other hand, the removed working head is easily lost wh...
