[0039] In the present invention, the headrest portion 13 is placed behind the patient's ears on both sides, and the headrest portion 13 is integrally in an arc structure. The headrest portion 13 has a certain elasticity. The second adjustment joint is placed at both ends of the headrest portion 13 and is used to stretch the headrest portion 13, so that the headrest portion 13 can adapt to the anatomical morphology of different individuals here and realize the fitting with the heads of different individuals.

[0040] The part of the surface of the headrest portion 13 in the present invention that contacts the surface of the dental chair headrest has a friction material, which can form a strong static friction effect with the tissue surface of the dental chair headrest, so as to strengthen the fixation of the device and compensate for the force transmitted by the hook 3 part and strengthen the stability effect of the device. In the present invention, the friction material uses fibers with a large friction coefficient, and is not limited to using bamboo original fibers, ramie fibers or cotton fibers.

[0041] A protruding adjustment component 2 is provided on the surface of the dressing strap 11 in the present invention, and the adjustment component 2 is used to adjust the left and right positions and angles of the hook 3.

[0042] As Figure 3 shown, a schematic structural diagram of the adjustment component 2 in the present invention is shown. The present invention provides a structure of the adjustment component 2, including: a housing, a slide rail provided in the housing, an adjustment screw provided in the slide rail, an adjustment block connected to the adjustment screw, and a slider connected to the adjustment block. The adjustment block is threadedly connected to the adjustment screw and is fixedly connected to the slider. The adjustment screw is provided on a threaded seat, and a manual knob is provided on one side of the adjustment screw. Both ends of the slider are provided on the slide rail. By rotating the manual knob, the adjustment screw rotates in place on the threaded seat, and the adjustment block moves relative to the adjustment screw, so that the adjustment block reciprocates along the length direction of the adjustment screw, and further drives the slider to reciprocate on the slide rail, realizing the change of the left and right positions of the hook 3.

[0043] Limit blocks are provided on both sides of the slide rail in the present invention to limit the movement stroke of the slider and the hook 3.
