As shown in fig. 2 to 6, one side of the base plate 21 is provided with a plurality of reference stoppers 25, and the other side of the base plate 21 is provided with a plurality of adjustment blocking mechanisms 26, and the reference stoppers 25 have an L-shaped structure and include an upwardly facing supporting surface 251 and a laterally facing abutting surface 252. The reference stopper 25 is used for positioning the base plate 111 of the bucket rod, the base plate 111 is placed above the supporting surface 251 in a vertical posture, one surface of the base plate 111 is abutted against the abutting surface 252, the other surface of the base plate is abutted against the U-shaped plate 112, one side surface of the U-shaped plate 112 is positioned on the reference supporting table 22, the transition surface of the U-shaped plate 112 is abutted against the base plate 111 by the adjusting blocking mechanism 26, and the opening direction of the U-shaped plate 112 is tightly attached to the base plate 111, so that the base plate 111 and the U-shaped plate 112 can be welded.

As shown in fig. 3, the adjustment blocking mechanism 26 includes a first swing block 261 rotatably connected to the base plate 21 about a horizontal axis, and a first screw rod 262 rotatably connected to the end of the first swing block 261 about the horizontal axis, a side pressing block 263 is provided at the front of the first screw rod 262, and a third assist handle 264 is provided at the rear of the first screw rod 262. With the reference stop 25 supported on the opposite side, the adjustment blocking mechanism 26 is clamped by adjusting the position of the first screw 262 relative to the first pendulum mass 261. Before assembly, the first swing block 261 can fall down, so that the U-shaped plate 112 can be horizontally arranged on the reference saddle 22, and the first swing block 261 can be erected when clamping is performed. The side press blocks 263 generate horizontal forces on the transition surface of the U-shaped plate 112.
