With the rotation of the fixed column, The fixed column will drive the triangular block to rotate around the axis of the fixed column. When the triangular block rotates to the bottom of the fixed pipe, the triangular block will squeeze the fixed pipe and raise the fixed pipe. When the triangular block moves to the fixed pipe After the side of the fixed pipe is lowered and returned to the original height by the action of gravity, the fixed pipe will have volatility, so that the fixed pipe will increase the spray range of the fixed pipe due to the swing.

To sum up, the utility model has the following beneficial effects:

After the two extruding hydraulic cylinders drive the two extruding plates to move toward each other, the two extruding plates can be clamped. In addition, the arc-shaped extruding plates can increase the working range of the extruding plates. , that is, gripping workpieces with more shapes. The setting of the rubber block increases the frictional force of the pressing plate, and the sliding motor can drive the gear to rotate around its own axis. Since the gear is in the fixed frame, it is restricted by the fixed frame and can only move along the length of the fixed frame. After the sliding motor is started, the sliding plate will move along the length direction of the fixed frame, so that the sliding plate has the ability to move and realize the purpose of adjusting the hydraulic fixture station.
