AI Technical Summary
Existing track connectors are prone to sliding and deflection during positioning, affecting the stability and smoothness of the adjustment block.
By employing a worm gear and worm meshing structure and a bidirectional screw design, and taking advantage of the fact that the worm gear and worm cannot transmit in reverse, combined with a threaded sleeve and a U-shaped connecting frame, precise positioning and stability of the adjusting block can be achieved.
This ensures the stability of the adjusting block during adjustment and use, prevents deflection, and improves the smoothness of the track movement.

Abstract
Claims
1. Rail connector comprising a rail connector body (1), an adjustment block (5) and a bidirectional screw (8), characterized in that: The main body (1) of the track connector has a mating groove (2) at both ends. A boss (3) integral with the main body (1) is provided between the two mating grooves (2). An adjusting block (5) is slidably provided at both ends of the top of the boss (3). A sliding groove (4) is provided on both sides of the top of the boss (3). A U-shaped connecting frame (6) is fixedly connected to the bottom of the adjusting block (5). A bidirectional screw (8) is spirally connected to the middle of the two U-shaped connecting frames (6). The two ends of the bidirectional screw (8) are spirally connected to the two U-shaped connecting frames (6). A worm gear (10) is fixedly installed on the outer periphery of one end of the bidirectional screw (8). A worm (11) is provided on one side of the worm gear (10). The worm (11) meshes with the worm gear (10). The worm gear (10) and the worm (11) are both located inside the boss (3).
2. The rail connector of claim 1, wherein: One end of the worm gear (11) is fixedly connected to a transmission rod (12). One end of the transmission rod (12) extends through the track connector body (1) to its outside. A cross groove (13) is provided at the end of the transmission rod (12) extending to the outside of the track connector body (1).
3. The rail connector of claim 1, wherein: A threaded sleeve (7) is fixedly embedded in the middle of the U-shaped connecting frame (6), and the U-shaped connecting frame (6) is helically connected to the bidirectional screw (8) through the threaded sleeve (7).
4. The rail connector of claim 1, wherein: The bidirectional screw (8) is located at the inner middle of the boss (3), and the two ends of the bidirectional screw (8) are movably connected to the inner wall of the boss (3) through the provided bearings (9).
5. The rail connector of claim 1, wherein: Screws (14) are provided on both sides of the outer walls of the mating grooves (2) at both ends of the main body (1) of the track connector, and the ends of the screws (14) extend into the interior of the mating grooves (2).
6. The rail connector of claim 5, wherein: A track (15) is inserted inside the docking groove (2). Screw holes (16) are provided on both sides of the end of the track (15). The screw (14) extends into the screw hole (16) and is fixedly connected by a nut.
