[0039] The tension block 2 includes a locking connection block 204 and a limiting block 205. The limiting block 205 is convexly arranged on the locking connection block 204, and a locking groove 203 with an opening is arranged between the limiting block 205 and the locking connection block 204, and the opening of the locking groove 203 faces the locking side edge 502 inside the profile 5; the locking connection block 204 is provided with two mounting holes 201 for connecting with the screw 4, and the mounting holes 201 are threaded holes. The corresponding parts of the box body 1 and the tension block 2 are provided with hollow holes for allowing the locking groove 203 to extend out, and the screw 4 passes through the hollow holes of the box body 1 and is connected with the mounting holes 201; the hollow holes of this embodiment are the ends of the sliding grooves 103. An elastic element 3 for resetting is arranged between the tension block 2 and the box body 1, and under the elastic force of the elastic element 3, the tension block 2 is urged to move to the side away from the locking side edge 502 of the profile 5.

[0040] Furthermore, a convex rib 206 is provided on one side of the locking connection block 204 close to the limit block 205, and the convex rib 206 extends into the locking groove 203; preferably, two convex ribs 206 are provided in this embodiment. In this embodiment, the edge of the limit block 205 is protruding, and forms a locking groove 203 for limiting with the side of the locking connection block 204. After installation, the locking side edge 502 of the profile 5 is located between the protruding edge of the limit block 205 and the side of the locking connection block 204. In addition, in this embodiment, the convex rib 206 is provided, and cooperates with the protruding edge of the limit block 205 to further clamp the locking side edge 502 of the profile 5, which is conducive to improving the locking stability of the entire transmission mechanism and preventing the transmission mechanism from shifting or loosening.
