[0043] The position limiter 61 is effectively connected to the sleeve support 3 through the communication shaft 621. When the position support 62 is pressed downward, the position support 62 moves downward, thereby driving the position limiter 61 to displace along the waist-shaped hole 611 through the communication shaft 621. At this time, the taper surface at the bottom of the position limiter 61 pushes the slope 610 of the two abutting plates 601, thereby effectively separating the two abutting plates 601. The taper end of the position limiter 61 moves from the top of the two abutting plates 601 to the middle of the two abutting plates 601, thereby clamping the two abutting plates 601.

In order to facilitate the rotation of the outer locking ring 63, a convex point is provided on the outer arm of the outer locking ring 63 to increase the friction; when the outer locking ring 63 rotates, the inner end surface of the inner flange 630 presses against the upper surface of the outer flange 622, effectively driving the limiting support 62 to move downward, which is convenient to operate. The inner locking ring 64 is connected to the inner wall of the outer locking ring 63 and located at the bottom of the outer flange 622. The outer wall of the sleeve support 3 is provided with an outer threaded section 623, and the inner locking ring 64 is threadedly connected with the outer threaded section 623. When the clamping plate 600 is clamped in the clamping groove 200, the inner locking ring 64 is fixed by being threadedly connected with the sleeve support 3, thereby realizing the fixation of the limiting support 62, the connection of the clamping jaw 60 is stable and reliable, and no other tools are needed during the entire operation process, which is convenient to use.

[0046] In some embodiments, the inner end surface of the inner flange 630 refers to the end surface of the inner flange 630 facing downward.

Thus, the clamping jaw 60 is connected stably and moves reliably under the action of the connecting rod 603. An arc-shaped groove 613 adapted to the connecting rod 603 is provided at the bottom of the limiting device 61. When the clamping plate 600 is clamped in the clamping groove 200, the arc-shaped groove 613 abuts against the connecting rod 603, thereby avoiding the interference of the connecting rod 603 with the limiting device 61.

[0048] In some embodiments, the universal vehicle-mounted expansion interface can further include two return springs 7, which are respectively located between the two abutting plates 601 and the inner walls on both sides of the sleeve support 3, and the two ends of each return spring 7 abut against the outer wall of the abutting plate 601 and the inner wall on one side of the sleeve support 3.

[0049] In some embodiments, the two return springs 7 are sleeved on the connecting rod 603.
