[0034] When the two worm gears 24 opposite to each other on both sides of the fixed slot bridge 9 rotate synchronously, the worm wheel 23 will be driven to rotate the threaded shaft A21. The rotation of the threaded shaft A21 will move the slider B22 on its surface and drive the movable slot bridge A10 and the movable slot bridge B11 to move, so that the movable slot bridge A10 and the movable slot bridge B11 are moved out from the two ends of the fixed slot bridge 9 to adjust the connection length.

[0035] The bottom of the fixed groove bridge 9 is rotatably connected to two transmission shafts 26, both ends of the two transmission shafts 26 are fixedly installed with bevel gears B27, the corresponding bevel gears B27 are meshed with bevel gears A25, and the middle of the two transmission shafts 26 are fixedly installed with rotating gears 28, and the two rotating gears 28 are staggered; the synchronous adjustment component 8 includes a through tube 29 and a cylindrical plug rod 30, the through tube 29 and the cylindrical plug rod 30 are fixedly installed at the bottom of the fixed groove bridge 9 and located between the two transmission shafts 26, and the internal movable part of the through tube 29 The rotating tube 31 is movably connected, and a limiting ring 33 is fixedly installed at one end of the rotating tube 31.

A large gear 32 is fixedly installed at one end of the limiting ring 33. The large gear 32 is meshed and connected between the two rotating gears 28. One end of the cylindrical insert rod 30 movably passes through the middle of the large gear 32 and extends to the inside of the rotating tube 31. A rotating wheel 34 is fixedly installed at one end of the surface of the rotating tube 31, so that it can be effectively adjusted.

[0036] The rotating tube 31 is rotated by the rotating wheel 34, and the rotation of the rotating tube 31 will drive the large gear 32 to rotate, and the rotation of the large gear 32 will drive the two rotating gears 28 to rotate, and the rotation of the two rotating gears 28 will drive the two transmission shafts 26 to rotate synchronously, and the rotation of the two transmission shafts 26 will drive the bevel gears B27 at both ends thereof to rotate, and the rotation of the bevel gear B27 will transmit the bevel gear A25 and drive the worm 24 to rotate and adjust.

[0037] The inside of the through-tube 29 is provided with concave groove A35, concave groove B36, concave groove C37 and concave groove D38 in sequence. Two plug blocks 39 are symmetrically installed on the surface of the rotating tube 31 located inside the through-tube 29. One end of the two plug blocks 39 is movably inserted in the concave groove C37, so that the rotating tube 31 can be rotated and adjusted stably and effectively. Two through holes 40 are symmetrically provided on the surface of the rotating tube 31. The two plug blocks 39 are respectively installed in the two concave grooves C37.

At the same time, the adjusting tube 51 is rotated to make the two local spiral transmission grooves 53 drive the two toggle blocks 54 to move. The movement of the two toggle blocks 54 will move the two inverted convex round blocks 50 to the inside of the adjusting tube 51 and compress the reset spring C52. The movement of the two inverted convex round blocks 50 will drive the ends of the two square latches 49 to move into the inside of the square socket A47.

[0045] When the square socket A47 is aligned with the square socket B48, the adjusting tube 51 is rotated in the opposite direction so that the end of the square pin 49 is inserted from the inside of the square socket A47 into the inside of the square socket B48.
