Novel clamp facilitating workpiece posture adjustment

The utility model relates to a novel clamp facilitating workpiece posture adjustment. The novel clamp comprises a transverse inner movable ring, an outer fixed ring coaxial with the inner movable ring and a base fixed to the outer fixed ring. The inner movable ring is rotationally connected with the outer fixed ring; the outer circular surface of the inner movable ring is rotationally connected with a clamping arm; one end of the outer fixing ring is provided with a plurality of clamping grooves which are evenly distributed in the circumferential direction and a plurality of rotation angle values which correspond to the clamping grooves in a one-to-one mode. The clamping groove is matched with the clamping arm; the novel clamp further comprises three sets of abutting bolts used for clamping a workpiece in a matched mode. The inner movable ring is provided with three sets of first threaded through holes in one-to-one correspondence with the three sets of abutting bolts. After improvement, the angle or posture
