Problems solved by technology

[0003] In the prior art, the screwdriver has a button part. The button part generally uses a rocker switch button, and there is a reset spring between the rocker button and the control switch. Long-term use of the rocker button will cause the reset spring to be strained and cause the button part to fail. Moreover, the prompting of the rocker button is low. When one end of the rocker button is pressed down, the user cannot be prompted, and the pressing force is easy to be excessive, resulting in damage to the button parts and affecting the use of the screwdriver.

Embodiment Construction

[0021] The invention provides an electric screwdriver, such as figure 1 and figure 2 As shown, it includes a screwdriver head 1 and a casing 2, the screwdriver head 1 is located in front of the casing 2, and the casing 2 is provided with a deceleration motor 3, a switch assembly 4 and a battery 5, and the screwdriver head 1 is connected to the On the output shaft that the motor shaft of motor 3 extends. The shell 2 is an integral sleeve shell or a split shell formed by joining two halves of the shell.

[0022] The switch assembly 4 includes a button 41 and a reversing switch 42. A dome 6 for bridging conduction is arranged between the button 41 and the reversing switch 42. The dome 6 is formed of a central convex metal sheet and an evenly distributed It is composed of four supporting ends 61 around the center concave metal sheet, and the supporting ends 61 are plugged into the slots 21 of the casing 2, and the dome 6 can also be arranged between the casing and the button. ...

Abstract

The invention discloses an electric screwdriver, which comprises a shell and a screwdriver bit arranged at the front end of the shell, wherein a switch assembly comprises a button and a reversing switch, the button is arranged on the outer wall of the shell, the reversing switch is arranged in the shell, metal domes which are used for bridging conduction are arranged between the button and the reversing switch, each metal dome consists of a central convex metal sheet and four supporting ends, and the supporting ends are evenly distributed on the circumference of the central convex metal sheet, and are inserted into slots of the shell. Since the button structure with the metal domes is adopted by the electric screwdriver, the metal domes can produce a prompting sound when deformation is restored, the prompting sound can feed the operating state information of the screwdriver back to a user, meanwhile, the experience of the user is optimized, and pressing experience is improved; because the shell is of a spliced structure, the structure is simple, production and assembly are convenient and portable, and the cost is low; because the electric screwdriver is provided with a combined structure, the manual-automatic screwdriver has a manual mode and an automatic mode which can be switched from each other, so the application range of the screwdriver is broadened.

Description

technical field [0001] The invention relates to a screwdriver, in particular to an electric screwdriver.
