a plurality of slide rail members 300, the plurality of slide rail members 300 are arranged at intervals, the slide rail members 300 are arranged on the inner surface of the fixing sleeve 100, and are connected with both sides of the fixing sleeve 100;

The sliding member 400 is used for fixing the electrodes, and each sliding rail member 300 is slidably provided with a plurality of sliding members 400 .

Specifically, during use, the fixing sleeve 100 is fixed on the head of the human body through the sheet-shaped strap 200, and then the sliding member 400 on the sliding rail member 300 is moved so that the sliding member 400 is located at the treatment position of the electrode, and then the electrode The sliding member 400 is inserted into the sliding member 400 from the mesh gap of the mesh fixing sleeve 100 , and is pressed and fixed by the sliding member 400 .

After the electrode is installed on the sliding member 400, the sliding member 400 is squeezed through the fixing sleeve 100 and the sheet-like strap 200, and the electrode is squeezed and fixed on the top of the human head under the action of elastic force, which increases the number of electrodes and the sliding member. 400 contact area, so that the electrode fixing effect is better; and by arranging the sliding rail member 300 and the sliding member 400 that can slide on the sliding rail member 300, the sliding member 400 can be adjusted according to the position of the electrode, and the electrode can be adjusted to Various positions of the human head are more convenient for medical staff to adjust the electrode scanning points of patients.

Referring to FIG. 1 , the sheet-like strap 200 includes two sheet-shaped sub-bands, and the two sheet-shaped sub-bands can be adhered to each other through Velcro to fix the fixed sleeve without restraining the chin of the human body like an elastic rope. The user is more comfortable.

Moreover, through holes are provided on the two-part straps to place the human ear without squeezing the human ear, and the use is more comfortable.
