[0023] Further, in order to provide power for the movement of transmission plate 43, a driving mechanism is arranged on the traction frame 1, specifically including a limiting groove 5, the limiting groove 5 is provided on the traction frame 1, the inner wall of the limiting groove 5 is rotatably installed with a driving plate 51, the driving plate 51 is installed with an adapter block 52, the adapter block 52 is in contact with one end of the transmission plate 43, the inner wall of the limiting groove 5 is provided with a rotating groove 53 on both sides, the inner wall of the two rotating grooves 53 is rotatably installed with a rotating shaft 54, the two rotating shafts 54 are respectively installed on both sides of the driving plate 51, the rotating shaft 54 is sleeved with a torsional spring 55, one end of the torsional spring 55 is installed on the outer surface of the rotating shaft 54, the other end of the torsional spring 55 is installed on the inner wall of the rotating groove 53, in use, the driving plate 51 is manually rotated to drive the adapter block 52 to move, the adapter block 52 drives the transmission plate 43 to move to the right side, so as to provide power for the movement of the transmission plate 43, by the arrangement of the torsional spring 55, when the driving plate 51 drives the transmission plate 43 to move, the torsional spring 55 is deformed, when it is needed to release the restriction on the optical cable body 2, the elastic restoring force of the torsional spring 55 can conveniently drive the driving plate 51 to reverse rotation, so as to conveniently remove the driving effect on the transmission plate 43
