The clamping protrusions 31 may be protrusion blocks, and the engaging parts 111 are grooves adapted to the protrusion blocks. By placing the clamping protrusions 31 in the engaging parts 111 at different positions or connecting the engaging parts 111 to the clamping protrusions 31 at different positions, the position of the pillow part 20 in the vertical direction is adjusted. The clamping protrusions 31 are fixedly arranged on the movable block 30. The movement of the movable block 30 drives the clamping protrusions 31 to be received in the groove 21 or protrude from the notch of the groove 21. The adaptation of the slider 11 to the slideway 22 makes the vertical adjustment of the pillow part 20 more stable. And the engaging parts 111 are arranged on the slider 11, the movable block 30 is movably arranged in the groove 21, and the clamping protrusions 31 are placed on the movable block 30, making its structure compact. And only by pressing the movable block 30 can the clamping protrusions 31 protrude from the groove 21 or be received in the groove 21, enabling the clamping protrusions 31 to be selectively connected or separated from the engaging parts 111 at the corresponding positions. Its adjustment structure is simple and compact, and the adjustment is more convenient and fast.

[0065] On the basis of the above embodiments, further, a support block 23 is vertically arranged at the notch of the pillow part 20 close to the groove 21.
