[0010] Preferably, a plurality of LED beads are embedded on the inner side of the mirror carrier, and each LED bead is electrically connected to a power source located inside the mirror carrier.

[0011] Compared with the prior art, the advantages of this utility model are as follows: The wearable device in this utility model uses a flexible strap, which can be tightened and fixedly connected to the user's forehead. The circumference of the wearable device can be adjusted at will with the help of the adjustment device, so that people with different head circumferences can wear it. A fixing device is fixedly connected to the wearable device to install a universal adjuster. The universal adjuster can adjust the position of one end relative to the other end, which helps to adjust the position of the reflector at the other end so that it can be adjusted at will according to the user's eye position. The reflector adopts an assembly connection and plug-in fixation, which makes it easy to disassemble and clean the reflector. A transparent glass lens is installed in the center of the reflector to isolate the user's eyes and prevent the patient's droplets from entering the user's eyes. A curved reflector surface is attached to the inner side of the mirror carrier. The reflector surface can focus light to the same side, which helps the user to observe the cavity with focused light.

[0012] Since the conical mirror carrier has a hole in the middle that allows light to pass through, the corresponding solution is to install an LED light on the inner side of the mirror carrier, with the light direction facing the wide opening of the mirror carrier. This facilitates observation while preventing light from shining through the hole into the user's eyes, making it more convenient and practical. Attached Figure Description

[0019] The following will describe specific embodiments and appendices. Figures 1-5The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0020] A forehead mirror includes a wearing component 1, which is a flexible band with a double-layer structure, except that the double layers are separated only in the middle. One end of the wearing component 1 is fixedly connected to an adjusting component 11, which includes a fixing frame 111. A pressure rod 112 is rotatably connected inside the fixing frame 111. A space 113 is provided between the pressure rod 112 and the fixing frame 111. Under the elastic force of 113, the pressure rod 112 always tends to press towards the side of the pressure rod 113. Therefore, when the other end of the wearing component 1 extends into the fixing frame 111, the free end of the wearing component 1 can be fixed relative to the fixing frame 111. The wearing piece 1 is made into a ring shape, which is convenient to wear on the user's head. A lever 115 is provided on one side of the pressure rod 112. The lever 115 extends through the fixing frame 111. An arc-shaped hole is provided on the fixing frame 111 corresponding to the movement trajectory of the lever 115. Therefore, the user can easily remove the wearing piece 1 from the fixing frame 111 by hand by levering the pressure rod 112. Several pressure blocks 114 are provided on the side of the pressure rod 112 away from 113. The pressure blocks 114 can increase the friction between the pressure rod 112 and the wearing piece 1, prevent the two from sliding relative to each other, and make the wearing piece 1 more firmly fixed on the patient's head.

[0021] A fixing member 2 is fixedly connected to a single layer in the middle of the wearing piece 1. The fixing member 2 has an insertion hole 21. The fixing member 2 is fitted onto the single layer of the wearing piece 1 through the insertion hole 21. The other layer of the wearing piece 1 isolates the fixing member 2 from the human body to prevent the fixing member 2 from directly contacting the person's forehead and causing discomfort. A slot 22 is provided vertically on the side of the fixing member 2 away from the wearing piece 1 for inserting and fixing the universal adjuster 3. The insertion function allows the universal adjuster 3 to be detachably connected, replaced when damaged, and disassembled for cleaning, increasing hygiene.
