A rotating plate 7 is movably sleeved on the outer surface of the sealing ring 5. The rotating plate 7 can rotate on the mounting shaft 11 according to the tightness of the sealing ring 5 to ensure that the sealing ring 5 does not fall off and to ensure the sealing between the sealing ring 5 and the inner wall of the electroplating protective sleeve.

[0040] The lower end of the fixing rod 18 is fixed to the end of the sealing ring 5 without the first through groove 19, and the fixing rod 18 is inserted into the first through groove 19 and the second through groove 20. The outer surface of the driving ring 3 is provided with a limiting groove 33, and the inner and outer diameters of the connecting sleeve 2, the driving ring 3 and the positioning sleeve 4 are the same.

[0041] A receiving groove 22 is provided on the inner wall of the connecting sleeve 2, a positioning groove 23 is provided on the inner wall of the receiving groove 22, a connecting groove 8 is provided on the lower end surface of the connecting sleeve 2, an annular groove 9 is provided on the inner wall of the connecting groove 8, a rotating shaft 24 is fixed on the outer surface of the upper end of the connecting sleeve 2, and the support plate 6 can rotate on the outer surface of the rotating shaft 24, thereby playing a transmission role.

[0043] A notch 30 is provided at the end of the telescopic slot 31, a baffle 32 is provided on the inner wall of the telescopic slot 31, a spring 27 is provided between the baffle 32 and the telescopic slot 31, a positioning block 28 is fixed to the side surface of the baffle 32 near the notch 30, the positioning block 28 corresponds to the positioning slot 23 and is clamped, and is movably connected, which plays a positioning role in the movement of the telescopic sleeve 1 in the storage slot 22 to prevent the telescopic sleeve 1 from rotating.

[0044] In actual use, the telescopic sleeve 1, the connecting sleeve 2, the driving ring 3 and the positioning sleeve 4 constitute an electroplating protective sleeve. When protecting the cylindrical electroplated object, the positioning block 28 is pressed to be stored in the telescopic groove 31, so that the positioning block 28 no longer hinders the stopper 21. The stopper 21 loses its limit. At this time, the connecting sleeve 2 can be pulled to move along the outer surface of the electroplated object, so that the telescopic sleeve 1 moves out of the storage groove 22, thereby changing the length of the electroplating protective sleeve.

The rotation of the driving ring 3 will pull one end of the sealing ring 5 into the other end of the sealing ring 5 through the fixing rod 18, so that the sealing ring 5 is tightened on the surface of the electroplated object. When the sealing ring 5 is tightened, it will pull the rotating plate 7 through the lower ring 13. It rotates on the mounting shaft 11, and the telescopic plate 14 will shrink inside the rotating plate 7 to ensure sealing between the multiple groups of rotating plates 7, thereby ensuring that the sealing ring 5 seals the lower port of the positioning sleeve 4, so that the electrolyte cannot enter the electroplating protective sleeve. Finally, stop pressing the positioning block 28, and at the same time make the upper surface of the positioning block 28 stick to the lower surface of the stopper 21, and the bottom surface of the inner wall of the telescopic sleeve 1 stick to the end of the electroplating object. Under the restriction of the stopper 21 and the positioning block 28, the support plate 6 cannot rotate, and the limit block 26 will be stuck in the limit groove 33, so that the drive ring 3 cannot rotate, so that the electroplating protective sleeve is fixed on the electroplating object. At this time, the adjustment function of the sealing diameter of the electroplating protective sleeve port is realized, so that the electroplating protective sleeve can adjust its own size according to the diameter of the cylindrical electroplating object and the length to be protected.
