The utility model provides a technical scheme that technical problem adopted does: an electric tool for screwing an outer polygonal part mainly comprises a clamping jaw, a clamping jaw telescopic device, a rotary table device, a transmission device, a motor, a control unit and a shell. The control unit starts a motor, the motor drives the rotary table device to rotate through the transmission device, the jaw expansion device stretches out of the jaws through rotation of the rotary table device or manual operation in advance, the jaws clamp parts, the rotary table device drives the jaws to clamp polygonal parts, and after the polygonal parts rotate to a proper position, the control unit drives the motor to rotate reversely, so that the jaws retract from the parts.

The utility model has the advantages that: compared with a common spanner used manually, the spanner is labor-saving and high in efficiency; compare with electronic box spanner, the utility model relates to an outer polygon part of multiple different specifications can be twisted to instrument, and through the breach design on casing and the carousel device, can be close the part of being twisted from a plurality of angles.

Detailed Description

As shown in figures 1-4, the electric tool for screwing the outer polygonal part mainly comprises a claw (1), a claw telescopic device (2), a turntable device (3), a control unit (4), a shell (5), a transmission device (6) and a motor (7). The jaw telescoping device is provided with an adjusting column (9) and mainly comprises an inner jaw adjusting disc (11) and an outer rotating disc (10). Through the first connecting shaft part (8) and the second connecting shaft part (12) of the transmission device, the electric tool in the embodiment is divided into an operating head and a handle. The operating head (as shown in figure 2) mainly comprises a claw (1), a claw telescopic device (2), a turntable device (3), a part of transmission device (6) and a part of shell (5), and the handle (as shown in figure 4) mainly comprises a control unit (4), a motor (7), a part of transmission device (6) and a part of shell (5).

When in use, the operating head and the handle are firstly assembled through the first connecting shaft part (8) and the second connecting shaft part (12). The outer polygonal part to be screwed is approached by the gaps on the shell (5) and the turntable device (3). Then, an adjusting column (9) of the inner clamping jaw adjusting disc (11) is pushed, the inner clamping jaw adjusting disc (11) and the outer rotating disc (10) rotate relatively, and the clamping jaw (1) extends out along a clamping groove of the outer rotating disc (10) to clamp an outer polygonal part to be screwed. Then, the control unit (4) starts the motor (7), and the motor (7) drives the turntable device (3) to rotate through various gear sets and connecting shafts of the transmission device (6), so that the polygonal parts clamped by the clamping jaws (1) are driven to rotate. After the polygonal part rotates to a proper position, the control unit (4) drives the motor (7) to rotate reversely, so that the clamping jaws (1) retract along the clamping grooves of the outer rotating disc (10), the shell (5) is aligned with the notches in the rotating disc device (3), and the electric tool is taken down from the part.
