[0021] Please see attached Figure 1 and attached Figure 2 The transmission locking assembly includes a rotating shaft 3, a threaded rod 4, a pulley mechanism and a sliding mechanism; the rotating shaft 3 is rotatably arranged in the cavity at the upper part of the support body 1 through a rotating bearing, and one end of the rotating shaft 3 extends to the outside of the support body 1 and is externally connected to a driving device; a pair of first slide grooves 8 are formed on both sides of the upper part of the support body 1, one end of a pair of threaded rods 4 is rotatably arranged in the first slide groove 8 through a rotating bearing, and the other end of the pair of threaded rods 4 is movably connected to the other end of a pair of blocks 13 through a sliding mechanism, so that the pair of blocks 13 can be slidably arranged in the first slide groove 8; a pair of pulley mechanisms are respectively arranged in the cavity at the upper part of the support body 1, and a pair of pulley mechanisms are respectively transmission-connected between a pair of threaded rods 4 and the two ends of the rotating shaft 3.

[0022] Preferably, each set of pulley mechanisms may include two pulleys and a belt, the two pulleys are coaxially fixed to the threaded rod 4 and the rotating shaft 3 respectively, and the belt is connected between the two pulleys for synchronous transmission of the two pulleys, thereby realizing synchronous rotation of the threaded rod 4 and the rotating shaft 3.

[0023] One end of the rotating shaft 3 can be connected to a hand crank, a motor or other driving device for manually or electrically controlling the rotation of the rotating shaft 3, so that the rotating shaft 3 drives the threaded rod 4 to rotate through the pulley mechanism, and a pair of symmetrically arranged threaded rods 4 rotate synchronously.
