[0038] In this embodiment, the reset spring 702 can drive the wedge-shaped locking block 701 to perform a reset movement, so that the wedge-shaped locking block 701 is engaged inside the locking groove 402, thereby limiting and fixing the slider 401 inside the sliding groove 304, and then connecting the first docking plate 3 and the second docking plate 4 together. The limiting block 3021 and the limiting groove 303 can limit the movable plate 302, so that the movable plate 302 will not detach from the two sides of one end of the first docking plate 3.

[0039] Example 3;

[0040] like Figure 1-7 As shown, in the pipe socket docking device according to an embodiment of the present invention, threaded rods 6 are movably connected to both sides of the first docking plate 3 via bearings. A first threaded groove 3022 is formed inside the limiting block 3021, and the threaded rod 6 is threadedly engaged within the first threaded groove 3022.

Then, the threaded rod 6 is rotated to drive the limiting block 3021 to slide inside the limiting groove 303, thereby causing the movable plate 302 to slide and clamp the first pipe 1 between the movable plate 302 and the fixed plate 301. After the clamping and fixing are stable, the fastening bolt 5 is rotated to move the fastening bolt 5 into the second threaded groove 3010 under the action of the second threaded groove 3010. This causes the first inclined surface 309 and the second inclined surface 502 to rub against each other, causing the plastic buckles 308 to move closer to each other under the thrust of friction, thereby clamping and fixing the threaded rod 6, and thus fixing the movable plate 302. At this time, the first pipe 1 is clamped and fixed. The installation operation of the first docking plate 3 is the same as that of the second pipe 2 and the second docking plate 4. After the second pipe 2 and the second docking plate 4 are installed, the slider 401 is embedded into the slide groove 304 and rotated and slid. When the slider 401 touches the wedge-shaped block 701, it will rub against it, causing the wedge-shaped block 701 to slide under the thrust of friction and drive the return spring 702 to compress. When the slot 402 moves to the position of the wedge-shaped block 701, the return spring 702 can drive the wedge-shaped block 701 to reset, so that the wedge-shaped block 701 is engaged in the slot 402, thereby limiting and fixing the slider 401 inside the slide groove 304, and then connecting the first docking plate 3 and the second docking plate 4 together, thus completing the docking installation operation of the first pipe 1 and the second pipe 2.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
