Since the movable sleeve plate 18 is slidably installed in the movable groove through the movable slider 17, the movable sleeve plate 18 is guided, and then the movable insertion strip 19 on the movable sleeve plate 18 is connected or separated from one of the movable sockets.

[0031] Working principle: When in use, first pull or push the installation L-shaped support rod 2 to make the installation L-shaped support rod 2 move in the direction away from or close to the installation hollow rod 1, so that it can be adjusted to a suitable length as needed, and the assembly recess 11 on the installation L-shaped support rod 2 is engaged with the external desktop, and at the same time, the two assembly bolts on the assembly recess 11 are rotated so that the two assembly bolts contact and tighten toward the position close to the desktop, and then the installation rotating block 6 is rotated to make the installation rotating block 6 drive the installation screw rod 5 to rotate, and then the installation sleeve block 4 moves along the direction of the installation screw rod 5, and then the installation sleeve block 4 is movably engaged with the installation guide rod 3, thereby guiding the installation sleeve block 4 and the installation strip 7, and then the installation strip 7 passes through the installation hollow rod 1 and is plugged into a mounting socket on the installation L-shaped support rod 2 to limit the position, so that it will not move or retract inside the installation hollow rod 1, thereby ensuring the adjustment and positioning effect.

[0032] Then, the positioning pull plate 16 is pulled, so that the positioning pull plate 16 drives the positioning insert 14 and the positioning spring 15 to move along the direction on the movable ring 13, and then the positioning insert 14 is separated from its corresponding positioning socket, and then the installation hollow rod 1 is pulled upward, so that the installation hollow rod 1 drives the installation L-shaped support rod 2 to move, and then the mobile extension rod 8 also slides inside the installation L-shaped support rod 2, followed by the mobile slider 12 on the mobile extension rod 8 sliding inside the mobile groove, and at the same time, the mobile slider 12 also drives the mobile ring 13 to slide along the direction on the installation L-shaped support rod 2, thereby driving the installation hollow rod 1 and the sponge cover to be adjusted to a suitable height according to the height of the human body as needed, and then the positioning pull plate 16 is released, so that the positioning spring 15 gives the positioning insert 14 a restoring force, so that the positioning insert 14 and its corresponding positioning socket are movably plugged into the limit, thereby adjusting the positioning of the installed L-shaped support rod 2 to ensure further adjustment and positioning effect.

[0033] Then bend and rotate the hollow rod 1, so that the hollow rod 1 drives the movable extension rod 8 and the movable rotating shaft 10 on the L-shaped support rod 2 to rotate along the direction of the assembly recess 11, so as to adjust to a suitable angle according to the needs of different people and contact the student's chest, and at the same time rotate the movable rotating block 22, so that the movable rotating block 22 drives the movable bidirectional screw 21 to rotate, and then the two movable sleeve plates 18 move on the movable bidirectional screw 21, so that the two movable sleeve plates 18 are close to or away from each other, because the movable sleeve plates 18 are slidably installed inside the movable groove through the movable slider 17, the movable sleeve plates 18 are guided, and then the movable insertion strip 19 on the movable sleeve plate 18 is connected or separated from one of the movable sockets, so as to limit the movable rotating shaft 10 after adjustment, and ensure the adjustment limit effect.
