[0031] Please refer to Figure 2In order to improve the flexibility and cleaning effect during operation, the dismounting mechanism 3 in the embodiment comprises a fixed seat 31, a driving motor 32, two fixed boxes 33, a rotating rod 34, four rotating spur gears 35, four toothed plates 36 and two clamping plates 37. The fixed seat 31 is arranged outside the high-pressure water jet head 2. The driving motor 32 is fixed to the left side of the fixed seat 31. The two fixed boxes 33 are rotatably connected to the opposite sides of the left and right side walls in the inner cavity of the fixed seat 31 through bearings. The rotating rod 34 is rotatably connected between the opposite sides of the top wall and the bottom wall in the fixed box 33 through a bearing. The four rotating spur gears 35 are fixed to the upper and lower ends of the outer surface of the rotating rod 34. The rotating spur gears 35 are in meshing connection with the toothed plates 36. By rotating the rotating rod 34 on the two sides, the rotating of the rotating rod 34 drives the rotating of the rotating spur gears 35. The rotating of the rotating spur gears 35 drives the movement of the toothed plates 36 in meshing connection with the rotating spur gears 35. The two clamping plates 37 are fixed to the opposite sides of the toothed plates 36 on the left and right ends. The movement of the toothed plates 36 can drive the movement of the clamping plates 37. The opposite sides of the two clamping plates 37 are each provided with a shock-absorbing plate 38. The opposite sides of the two shock-absorbing plates 38 are each fixed with a plurality of spring shock-absorbing rods 39. The opposite movement of the two clamping plates 37 can drive the movement of the spring shock-absorbing rods 39 and the shock-absorbing plates 38, thereby releasing the high-pressure water jet head 2 from the limiting, and then the high-pressure water jet head 2 is held to flush the narrow space and complex pipeline on the surface of the workpiece. The shock-absorbing plates 38 and the plurality of spring shock-absorbing rods 39 can absorb the shock of the high-pressure water jet head 2 when the water flow from the high-pressure water jet head 2 is large, thereby preventing the fixing effect of the high-pressure water jet head 2 from being affected.

The shock-absorbing plate 38 is a rubber plate. The opposite sides of the two clamping plates 37 are each fixed with a rubber pad. The other end of the spring shock-absorbing rod 39 is fixed with the rubber pad.

[0034] In addition, when the angle of the high-pressure water jet nozzle 2 needs to be adjusted, the driving motor 32 is started to rotate the output shaft of the driving motor 32 to drive the left fixed box 33 to rotate. The rotation of the left fixed box 33 can drive the rotation of the rotating rod 34, the rotating straight gear 35, the toothed plate 36, and the left end clamping plate 37, thereby changing the angle of the high-pressure water jet nozzle 2. At this time, the right end clamping plate 37 drives the right fixed box 33, the rotating rod 34, the rotating straight gear 35, and the toothed plate 36 to rotate with the change of the angle of the high-pressure water jet nozzle 2.

The outside of the moving rod is fixedly connected with a limiting block located in the inside of the fixed rod. One side of the fixed rod is provided with a penetrating hole matched with the moving rod. By arranging the limiting block, the moving rod is prevented from being separated from the fixed rod during movement.

The lifting table 45 is fixed on the upper surface of the lifting plate 44. The movement of the screw sleeve 43 drives the hinged seat fixed on the surface of the screw sleeve 43 to move, thereby driving one end of the hinged rod to move the other end of the hinged rod. The movement of the other end of the hinged rod drives the hinged seat at the upper end to move, so that the lifting plate 44 moves upward, thereby moving the lifting table 45, and the height of the high-pressure water jet nozzle 2 can be raised. The positioning plate 46 is fixed on the right end of the upper surface of the lifting table 45, and the electric push rod 47 is fixed on the right side of the positioning plate 46.
