[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1-6As shown, the valve body of the electric tool of the utility model comprises a threaded connection part 1 and a valve body part 2, one end of the threaded connection part 1 is fixedly welded with the valve body part 2, a plurality of limit slots 3 are equidistantly provided on the outer wall of the valve body part 2, a rotating ring 6 is rotatably connected to the end face of the threaded connection part 1, a plurality of installation slots 8 are equidistantly provided on the inner wall of the threaded connection part 1, and retractable positioning clamping columns 7 are provided inside the plurality of installation slots 8.

[0021] Specifically, through the cooperation of the rotating ring 6 on the surface of the threaded connection part 1 and the internal positioning clamp 7, the threaded connection part 1 can be threadedly connected to the connecting part and then locked, thereby avoiding loosening of the threaded connection part, improving the firmness of the connection of the power tool valve body, and avoiding the problem of loosening.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the valve body of the electric tool of the utility model, the positioning column 7 is connected with both sides of the inner wall of the installation groove 8 by insertion, the middle part of the positioning column 7 is fixedly provided with a limit ring 9, one end of the positioning column 7 is nested and connected with a return spring 10, one end of the return spring 10 is fixedly connected to the groove wall of the installation groove 8, and the other end of the return spring 10 is fixedly connected to the side of the limit ring 9.

[0023] Specifically, the cooperation between the return spring 10 and the limit ring 9 facilitates the control of the extension and retraction of the positioning clamping column 7 .

[0024] One end face of the positioning clamping column 7 is an inclined surface, and the inner wall of the rotating ring 6 is provided with a wedge-shaped groove 11 adapted to the inclined surface.

[0025] The other end of the positioning clamping column 7 is nested and connected with a positioning hole provided on the surface of a threaded connection column matched with the threaded connection part 1 .

[0026] Specifically, by nesting the positioning clamping column 7 with the threaded hole on the surface of the connecting threaded column, the threaded connection of the threaded connection part 1 is locked, thereby avoiding the problem of the threaded connection part 1 being loosened due to vibration.

[0027] An annular slideway 12 is provided at the connection between the threaded connection part 1 and the rotating ring 6 . Slide blocks 13 matching the annular slideway 12 are fixedly provided on both sides of the side of the rotating ring 6 . The slide blocks 13 are slidably connected to the annular slideway 12 .

[0028] Specifically, the cross section of the annular slideway 12 is T-shaped, and the slider 13 slides inside the annular slideway 12 , thereby preventing the rotating ring 6 from being separated from the threaded connection part 1 while ensuring the rotation of the rotating ring 6 .

[0029] A plurality of anti-skid grooves 4 are equidistantly formed on the outer wall of the threaded connection part 1 , and a plurality of reinforcement strips 5 fixedly connected to the threaded connection part 1 are provided between two adjacent anti-skid grooves 4 .

[0030] Specifically, the structural strength of the threaded connection part 1 is increased by the provision of the reinforcement strip 5, and the stability of the rotation of the threaded connection part 1 is improved by the provision of the anti-slip groove 4 when the threaded connection part 1 is threadedly connected to the connecting part.

[0031] Specifically, when assembling the valve body of the electric tool, the threaded connection part 1 of the electric tool valve body is firstly threadedly connected with the threaded column of the electric tool. When the threaded column is completely threadedly connected with the threaded connection part 1, the positioning hole on the surface of the threaded column is aligned with the position of the positioning clamping column 7. Then, the rotating ring 6 on the outer surface of the threaded connection part 1 is manually rotated, and the positioning clamping column 7 is moved by the rotation of the rotating ring 6, so that one end of the positioning clamping column 7 passes through the installation groove 8 and is nested with the positioning hole, thereby locking the threaded column inside the threaded connection part 1, thereby improving the firmness of the connection between the electric tool valve body and the threaded connection column, and avoiding the loosening of the threaded connection due to the vibration of the electric tool operation, thereby affecting its use.
