A first long side plate 5 is provided on one side of the bracket 10, and a short side plate 7 is provided on the opposite side of the first long side plate 5. A set screw 6 is installed on the short side plate 7. This positioner uses the outer shape of the assembly frame as the positioning support point to position the device and locks it with a locking nut. It uses a clamping block with a preset 8-degree angle. The two ends of the clamping block have opposite preset angles. The preset angle can be reversed by rotating it 180 degrees. A rod end spherical bearing is installed on the device support block to achieve secondary adjustment of the clamping block angle to adapt to different angles for good fit and clamping. It has the advantages of a large angle adaptation range, a large contact surface, reliable clamping, high safety, simple operation, and convenient use.
