This invention provides a fully free-degree-of-freedom motor-driven joint, relating to the field of underwater robot technology. It includes an upper robotic arm and a lower robotic arm, which are interconnected by a drive mechanism. The drive mechanism controls the angle adjustment of the upper robotic arm. In this invention, a motor drives a first rotating shaft to rotate, which in turn drives a movable block and the upper robotic arm to rotate through the engagement of a second positioning block and a second positioning groove, and a first gear and a second gear. This achieves fully free-degree-of-freedom rotation of the upper robotic arm through a single drive joint, reducing the overall size and weight of the underwater robot while improving its overall flexibility.

This utility model discloses an electric bicycle frame made of welded profiles and plates, connected by rivets. It includes a buffer protection structure, with a plate riveted to the lower end of the buffer protection structure. A support frame is riveted to the side end of the plate by a first rivet. A saddle bracket is welded to the lower end of the support frame, and a reinforcing frame is welded to the center of the support frame. The buffer protection structure provides top protection for the plate. A second support top frame is welded and fixed to the first support top frame. A vertical frame is welded to the side end of the second support top frame, and a second rivet is provided at the lower end of the vertical frame. The vertical frame is riveted to the plate by the second rivet. This utility model is an electric bicycle frame made of welded profiles and plates, connected by rivets. Through the structural design, it achieves the purpose of connecting and fixing the welded pipe electric bicycle frame.
