the two limiting columns (10-4) are respectively and vertically fixed on the left rear side wall and the right front side wall in the mounting groove (8); the limit post (10-4) and the toggle rod (10-3) are movably and limitedly arranged;
when the connecting column (9-12) moves to the left side of the mounting groove (8), the upper toggle rod (10-3) is in limit interference with the limit column (10-4), the limit column (10-4) drives the toggle piece (10-2) to rotate through the toggle rod (10-3), then the right end of the toggle piece (10-2) is pressed and pushed by the push switch (10-1), the push switch (10-1) closes the electric control valve (5), then the connecting column (9-12) moves rightwards and moves to the right side of the mounting groove (8), and similarly, the toggle piece (10-2) is pressed and pushed by the push switch (10-1), and the push switch (10-1) controls the electric control valve (5) to be opened;
the part of the guide rod (9-13) which is in movable contact with the hydraulic valve body (1) is fixedly provided with a sealing gasket (11), and the inner side wall of the sealing gasket (11) is in contact with the outer side wall of the guide rod (9-13); the sealing performance of the connection between the guide rods (9-13) and the inner side wall of the hydraulic valve body (1) is improved through the sealing gasket (11);
the annular groove (12) is formed in the adjusting plate (9-3) around the adjusting column (9-5); the rear end of an output shaft of the rotating motor (9-10) is movably inserted into the annular groove (12); the annular groove (12) is arranged to limit and guide the relative operation of the rotary motor (9-10) and the adjusting plate (9-3), so that the stability of movement is improved;
a cutter ring (13) is fixedly arranged on the left side wall of the rubber plug (9-15), and the peripheral wall of the cutter ring (13) is contacted with the inner side wall of the pressure oil way (3); and scraping accumulated oil on the inner side wall of the pressure oil way (3) through a cutting ring (13).
