[0025] The supporting component 52 comprises three bearings, the outer surfaces of the three bearings being fixedly connected with the inner peripheral wall of the clamp base 1, and the inner peripheral walls of the three bearings being fixedly connected with the outer surface of the cylindrical bin 51, so as to facilitate the rotation of the cylindrical bin 51 in the clamp base 1.
[0026] In addition, a supporting rod is fixedly installed between the front and rear sidewalls of the inner cavity of the cylindrical bin 51, one end of the supporting rod penetrating the ball 2, and the ball 2 being rotatably installed on the outer surface of the supporting rod, so as to facilitate the rotation of the ball 2 around the supporting rod.
[0027] The above technical scheme makes the multi-stage electric push rod in the feeding component 57 work, and the telescopic end of the multi-stage electric push rod drives the rack 54 to move left and right in the support frame 53 through the connecting piece. Since the rack 54 is engaged with the special gear 55 on the ball 2, the movement of the rack 54 drives the ball 2 to rotate around the support rod.

[0034] The multi-stage electric push rod in the feeding component 57 works, the telescopic end drives the rack 54 to move left and right in the support frame 53 through the connecting piece, since the rack 54 is meshed with the special gear 55 on the ball 2, the movement of the rack 54 drives the ball 2 to rotate around the support rod, the ball 2 is connected with the tool holder 3 and the turning tool 4 at the bottom, so that the rotation of the ball 2 changes the angle of the turning tool 4 in the vertical direction, the angle fine adjustment of the turning tool 4 in the vertical direction is realized, and the connecting plate in the anti-falling component 56 slides in the through groove of the support frame 53, so that the rack 54 is prevented from falling off from the support frame 53, and the stability of the fine adjustment structure is ensured.
