Through above-mentioned technical scheme, linear actuating mechanism one end and sleeve 11 fixed connection, the other end is connected with the accent curved body 7. When the linear driving mechanism stretches and contracts, the transmission shaft 4 can be indirectly pushed to rotate relative to the ball seat 2; based on the designs of the universal joint sleeve 51 and the sliding body 52, the universal joint sleeve 51 can swing in a small amplitude relative to the sliding body 52, so that the current structure of the transmission shaft 4 can be better adapted; and the sliding between the sliding body 52 and the universal joint sleeve 51 is similar to that between the sliding body 52 and the universal joint sleeve 51, and the sliding body can be better adapted to the current position of the transmission shaft 4 by helping the distance between the universal joint sleeve 51 and the transmission shaft 4 to avoid the situation of pulling or clamping stagnation. Thus, not only is the driving force of the driver transmitted to the drill bit at the end of the drive shaft 4 via the joint sleeve 51 and the slider 52.
