A motor is fixedly installed inside the right-side crossbeam body. A turntable is connected to the output shaft of the motor. An extension rod is hinged to the front side of the turntable. A plug is installed inside the right-side crossbeam body. A limiting cylinder is fixedly installed inside the right-side crossbeam body. A limiting plate is installed inside the limiting cylinder. A return spring is installed at the bottom of the limiting plate. A locking block is installed at the top of the limiting plate. A pull rod is connected to the bottom of the limiting plate.
[0007] Furthermore, the extension plate extends from the side of the left crossbeam body away to the interior of the right crossbeam body, and a slot is provided inside the extension plate.
[0008] Furthermore, two limiting rods are fixedly installed inside the crossbeam body on the right side, and a limiting block is fixedly installed on the right side of the insert block, with both limiting rods penetrating the limiting block.
[0009] Furthermore, the side of the extension rod away from the turntable is connected to the right side of the limiting block, and the side of the insertion block away from the limiting block extends into the slot.
[0010] Furthermore, the card block has a card slot inside, the limiting cylinder is connected to the inner bottom wall of the crossbeam body on the right side, and there are two reset springs.
[0011] Furthermore, the two reset springs are connected to the inner bottom wall of the limiting cylinder on the side away from the limiting plate, the pull rod extends to the outside of the right crossbeam body on the side away from the limiting plate, and the top of the locking block extends into the slot.

The limiting cylinder 405 is fixedly installed inside the right crossbeam body 2. The limiting plate 406 is installed inside the limiting cylinder 405. The return spring 407 is installed at the bottom of the limiting plate 406. The locking block 408 is installed at the top of the limiting plate 406. The pull rod 409 is connected to the bottom of the limiting plate 406.
[0022] exist Figure 1 and Figure 2 In the middle, the extension plate 3 extends from the side away from the left crossbeam body 2 to the inside of the right crossbeam body 2. The inside of the extension plate 3 is provided with a slot. The crossbeam body 2 is fixed by setting the support leg 1, and the two crossbeam bodies 2 are quickly connected and fixed by the extension plate 3.
[0023] exist Figure 1 and Figure 2 In the middle, two limiting rods 5 are fixedly installed inside the right crossbeam body 2, and a limiting block 6 is fixedly installed on the right side of the insertion block 404. Both limiting rods 5 pass through the limiting block 6. By setting the limiting rods 5 and the limiting block 6, the insertion block 404 is more stable when moving.
[0024] exist Figure 1 and Figure 3In this design, by setting up a connecting mechanism 4, the various structures of the connecting mechanism 4 can cooperate with each other to achieve quick connection and fixation of the crossbeam body 2, thus saving time and manpower. The connecting mechanism 4 includes a motor 401, a turntable 402, an extension rod 403, an insert block 404, a limiting cylinder 405, a limiting plate 406, a reset spring 407, a locking block 408, and a pull rod 409. The side of the extension rod 403 away from the turntable 402 is connected to the right side of the limiting block 6, and the side of the insert block 403 away from the limiting block 6 extends into the slot.
[0025] exist Figure 2 and Figure 3 In the middle, the card block 408 has a card slot inside, the limiting cylinder 405 is connected to the inner bottom wall of the right crossbeam body 2, and there are two reset springs 407.

[0027] In summary, this splicing beam square tube connector, by setting up a motor 401, the controller drives the motor 401 to start, which drives the turntable 402 and the extension rod 403 to rotate, thereby pulling the insert block 404 to move back and forth. By setting up a limiting cylinder 405 to limit the limiting plate 406, a person can pull the pull rod 409 to make the limiting plate 406 squeeze the reset spring 407, which will cause the locking block 408 to exit the slot.
[0028] Furthermore, during use, firstly, the support leg 1 and the crossbeam body 2 are fixed and stabilized with screws. Then, push the left support leg 1 to the right so that the extension plate 3 enters the right crossbeam body 2. At this time, the controller drives the motor 401 to start, thereby driving the turntable 402 and the extension rod 403 to rotate, driving the insertion block 404 to move to the left and enter the slot. Then, a person pulls the lever 409 down to ensure that the insertion block 404 is fully inserted into the slot. Finally, a person releases the lever 409, the reset spring 407 resets, thereby allowing the locking block 408 to enter the slot, further locking the insertion block 404.
