The rack 1104 is pushed to slide on the third guide slide bar 1105 through the linkage rod 1110, and the position of the rack 1104 is adjusted. The rack 1104 drives the meshing gear 1103 to rotate, and the gear 1103 is rotated. The wheel 1103 drives the rotating shaft 1101 and the impeller 1102 to rotate. The impeller 1102 can turbulently stir the plating solution, which can improve the efficiency of metal ion dispersion in the plating solution, and effectively improve the efficiency of metal ion adsorption to the decorative parts of the metal products to be electroplated to form a coating. When the fixed plate 4 is reset upward, the L-shaped pressure rod 13 is separated from the movable plate 1108. At this time, the movable plate 1108 is pushed to reset under the action of the second elastic member 1109. The movable plate 1108 pulls the rack 1104 to reset through the linkage rod 1110, thereby driving the impeller 1102 to rotate again, and the plating solution is turbulently stirred again, which is highly practical.

[0031] Working principle: During the electroplating process, the metal product decorative parts to be processed are placed in a fixed position on the decorative parts electroplating hanger 7, and the horizontal position of the decorative parts electroplating hanger 7 is moved by the horizontal linear slide 2 to move it above the electroplating tank to be processed, and the vertical position of the decorative parts electroplating hanger 7 is moved by the vertical linear slide 14 to move the metal product decorative parts to be processed into the electroplating solution of the electroplating tank for electroplating, and the fixed plate 4, the horizontal moving plate 5, the vertical moving plate 6, the decorative parts electroplating hanger 7 and the drying component 8 move synchronously; When the longitudinal movable plate 6 moves down to the bottom end of the vertical plate 3, the lower matching trapezoidal block 1001 contacts the lower trapezoidal block 1002, and the longitudinal movable plate 6 continues to move down, so that the lower matching trapezoidal block 1001 and the inclined surface of the lower trapezoidal block 1002 cooperate and slide, thereby pushing the longitudinal movable plate 6 and the transverse movable plate 5 to move right synchronously, so that the roller 601 moves to the position corresponding to the position of the guide block 901, and the fourth magnetic member 405 is fixed by adsorption with the third magnetic member 404, so as to fix the position of the movable plate 5 and the longitudinal movable plate 6; After the electroplating treatment of the metal product decorative parts is completed, the longitudinal linear slide 14 moves the decorative part electroplating hanger 7 upward to reset. When the longitudinal movable plate 6 moves to the guide block 901, the roller 601 contacts the inclined surface of the guide block 901. As the longitudinal movable plate 6 continues to rise, the longitudinal movable plate 6 is pushed to move in the direction away from the vertical plate 3 and squeeze the first elastic member 503. When the roller 601 is separated from the guide block 901, the longitudinal movable plate 6 can be quickly reset under the action of the first elastic member 503, thereby realizing the rapid forward and backward shaking of the longitudinal movable plate 6 and the decorative part electroplating hanger 7, and the electroplating liquid on the metal product decorative parts can be quickly thrown off and separated, which is used to reduce the residual electroplating liquid on the metal product decorative parts. Through the setting of the shock absorber 902, when the longitudinal movable plate 6 is reset, the longitudinal movable plate 6 contacts the shock absorber 902, thereby reducing the impact force on the vertical plate 3 and improving the service life; When the longitudinal movable plate 6 moves and resets to the top of the vertical plate 3, the upper matching trapezoidal block 1003 contacts the upper trapezoidal block 1004, and continues to move upward through the longitudinal movable plate 6, so that the upper matching trapezoidal block 1003 and the inclined surface of the upper trapezoidal block 1004 cooperate and slide, thereby pushing the longitudinal movable plate 6 and the transverse movable plate 5 to move to the left synchronously, so that the avoidance groove 602 moves to the position corresponding to the guide block 901 and the shock absorber 902, and is fixed by the second magnetic member 403 and the first magnetic member 402 to fix the longitudinal movable plate 6 when it moves to the left. During the next electroplating process, when the longitudinal movable plate 6 moves downward, the longitudinal movable plate 6 can pass through the guide block 901 and the shock absorber 902 through the avoidance groove 602 to avoid obstruction to the downward movement of the longitudinal movable plate 6. During the process of the fixed plate 4 descending, when the metal product decorative parts on the decorative part electroplating hanger 7 are placed in the electroplating solution of the electroplating tank, the L-shaped pressure rod 13 contacts the movable plate 1108, and the movable plate 1108 slides downward on the fourth guide slide bar 1106, and the rack 1104 is pushed to slide on the third guide slide bar 1105 through the linkage rod 1110, and the position of the rack 1104 is adjusted, and the rack 1104 drives the meshing gear 1103 to rotate, and the gear 1103 drives the rotating shaft 1101 and the impeller 1102 to rotate, and the impeller 1102 can stir the plating solution by turbulence, which can improve the efficiency of metal ion dispersion in the plating solution, and effectively improve the efficiency of metal ion adsorption to the decorative parts of metal products to be electroplated to form a plating layer. When the fixed plate 4 is reset upward, the L-shaped pressure rod 13 is separated from the movable plate 1108. At this time, the movable plate 1108 is pushed to reset under the action of the second elastic member 1109, and the movable plate 1108 pulls the rack 1104 to reset through the linkage rod 1110, thereby driving the impeller 1102 to rotate again, and stirring the plating solution again.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
