[0021] The side wall of annular seat 2 in the embodiment is provided with screw hole II for screw rod 4 to pass through, screw rod 4 is screwed with screw hole II, and the number of screw rod 4 is two groups, which are evenly arranged on annular seat 2.

[0022] As shown in Figure 1 A circle of circular ring 11 is provided at the opening at the top of barrel 1, cover plate 12 is provided at the opening at the top of circular ring 11, bearing is provided in the side wall of circular ring 11 for fixing the end of screw rod 4, liquid inlet pipe is provided at the top of barrel 1, and liquid outlet pipe is provided at the bottom of barrel 1.

[0023] As shown in Figure 2 A plurality of accommodation grooves with arcuate cross section are provided on the upper and lower side walls of sliding slot 3, ball 13 is provided in the accommodation groove and extends to the corresponding end face of orifice plate 6 in sliding slot 3, and the side wall of the edge of orifice plate 6 in sliding slot 3 is solid structure.

[0025] The use method of the present application: the motor I5 drives the screw rod 4 to rotate in the screw hole II in the annular seat 2, and then drives the annular seat 2 to drive the hole plate 6 and the fixing mechanism 10 and other components to move upwards in the barrel body 1, so that the fixing mechanism 10, the top rod 14 and the limiting rod 15 slide out of the opening of the opened circular ring 11, and in the process, the hole plate 6 drives the vertical pipe 7 to slide upwards on the circular hole in the bottom wall of the barrel body 1 and the vertical rod 8;

[0026] Then the circuit board is inserted into the corresponding rectangular notch 102 on the two groups of vertical plates 101 for support and fixation. It should be noted that when the circuit board is installed and inserted into the rectangular notch 102, the end of the circuit board is pressed and fixed by the vertical end of the L-shaped seat 104 extending into the rectangular notch 102, and at the same time, the rear end of the circuit board abuts against the top rod 14. When a plurality of circuit boards are sequentially placed on the fixing mechanism 10, the limiting rod 15 screwed on the hole plate 6 presses the front end of the circuit board, so that the circuit board located in the two groups of fixing mechanisms 10 is fixed by the top rod 14 and the limiting rod 15, preventing the circuit board from sliding horizontally out of the rectangular notch 102. Further, rotating the screw rod 105 in the screw hole I of the L-shaped seat 104 drives the L-shaped seat 104 to move downwards in the clamping groove 103, so that the horizontal end of the L-shaped seat 104 presses on the top end surface of the circuit board in the rectangular notch 102. By rotating the screw rod 105, a plurality of L-shaped seats 104 are driven to move downwards to press and fix the ends of the circuit boards, preventing the circuit boards from swinging up and down during subsequent immersion and washing. In the above process, when the screw rod 105 rotates in the screw hole I to drive the L-shaped seat 104 to move, the clamping groove 103 clamps the side wall of the L-shaped seat 104 to prevent it from rotating with the screw rod 105, and when the L-shaped seat 104 presses and fixes the circuit board, the top end portion of the side wall of the L-shaped seat 104 is always clamped in the clamping groove 103;

[0027] Next, the motor I5 drives the annular seat 2, the hole plate 6, the fixing mechanism 10 and the circuit board to slide into the barrel body 1 and immerse in the liquid through the screw rod 4. At this time, the motor II 9 drives the vertical pipe 7 to rotate through the vertical rod 8, and the vertical pipe 7 drives the hole plate 6, the fixing mechanism 10 and the circuit board fixed thereby to rotate, so as to rotate and wash the same. When the hole plate 6 rotates, it drives the ball 13 on the sliding groove 3 to slide along the edge of the hole plate 6. The annular seat 2 can support and fix the edge of the hole plate 6 through the ball 13, without affecting the rotation of the hole plate 6. The annular seat 2 moving up and down can also drive the hole plate 6 to move in the same direction. In the above process, since the internal opening cross section of the vertical pipe 7 is polygonal and the size of the vertical rod 8 is matched with the internal opening cross section of the vertical pipe 7, when the motor II 9 drives the vertical rod 8 to rotate, the side wall of the vertical rod 8 abuts against the corresponding inner side wall of the vertical pipe 7 to drive the vertical pipe 7 to rotate together with the vertical rod 8.

[0028] The application has been described in detail, but it should be understood that the detailed description is merely intended to teach the best options for practicing the application. The best options should not be used to limit the overall scope of the application. Other options can be developed and used without departing from the overall scope of the claims.
