The utility model relates to a transmission rod connecting and fastening sleeve which comprises a sleeve body and two transmission rods which can be inserted into the sleeve body and rotate, two arc-shaped column grooves which are symmetrically distributed on the two sides of the sleeve body with the circle center of the sleeve body as the axis are formed in the side wall of the sleeve body, and the transmission rod connecting and fastening sleeve further comprises semi-cylindrical positioning blocks which can be embedded into the arc-shaped column grooves. A semi-cylindrical groove is formed in the side wall of the transmission rod, the height of the semi-cylindrical groove is larger than or equal to that of the arc-shaped column groove, and two first positioning holes used for fixing the semi-cylindrical positioning blocks are formed in the arc-shaped column groove. The transmission rod connecting and fastening sleeve is faster in positioning and simpler and more convenient to install. 本实用新型涉及一种传动杆连接紧固套筒，包括
