[0048] The inner side of the annular cylinder 72 is rotatably installed with an inner gear ring 76, the inner gear ring 76 is fixedly connected with the inner rotating piece 74, the side away from the mounting plate 5 of the fixed rod 71 is rotatably installed with a reciprocating screw rod 77, the outer side of the reciprocating screw rod 77 is fixedly connected with a gear part 78, the outer side of the reciprocating screw rod 77 is sleevedly installed with an adjusting sleeve 79, and the outer side of the adjusting sleeve 79 is fixedly connected with a side rod 710.

[0049] The top of the annular cylinder 72 is fixedly installed with a water inlet pipe 73, the impact plate 75 is arranged in an array, the inner gear ring 76 is meshingly connected with the gear part 78, four fixed rods 71 are symmetrically arranged, and the four fixed rods 71 are respectively fixed to the front, back, top and bottom surfaces of the outer side of the fixed box 6. The number of reciprocating screw rods 77 is the same as that of the fixed rods 71.

[0050] The end away from the adjusting sleeve 79 of the side rod 710 is rotatably installed with a bent rod 713, the outer side of the clamping plate 812 is slidably installed with a cleaning sleeve 714, and the bent rod 713 is clampedly installed with the cleaning sleeve 714.

[0051] The adjusting sleeve 79 is threadedly connected to the reciprocating screw 77. The side rod 710 is symmetrically arranged on the outside of the adjusting sleeve 79. The annular cylinder 72 is connected to the water inlet pipe 73. The bent rod 713 is hinged and fixed to the side rod 710.

[0052] A spray head 712 is fixedly installed on the side of the water outlet pipe 711 near the clamping plate 812. The water outlet pipe 711 is connected to the annular cylinder 72. The cleaning sleeve 714 is slidably connected to the clamping plate 812. A locking block is fixedly connected to the end of the bent rod 713 away from the side rod 710.

[0054] Example 1: As Figure 4 - Figure 11 As shown, by setting the cleaning component 7, when it is necessary to clean the clamping plate 812, the operator connects the water inlet pipe 73 to an external high-pressure water source. The high-pressure water enters the annular cylinder 72 and is sprayed out through the water outlet pipe 711 and the nozzle 712, thereby rinsing the clamping plate 812.
