[0024] The eye tracker body 1 is provided with fixing belts 2 on both sides of the eye tracker body 1. The fixing belts 2 are made of plastic material and have a certain elasticity, so that when the two pull ropes 4 loosen the two fixing belts 2, the two fixing belts 2 can be reset under the action of their own elastic force. When the two pull ropes 4 are tightened and the two fixing belts 2 are reset, the two pull ropes 4 are also stretched to the longest to avoid being scattered. A connecting component is provided between the two fixing belts 2 and the eye tracker body 1. The connecting component includes a mounting block 14 and a T-block 16. The mounting block 14 is fixedly arranged on one side of the eye tracker body 1. A T-slot 15 is arranged on the mounting block 14. One end of the fixing belt 2 is fixedly arranged on one side of the T-block 16. The T-block 16 is matched with the T-slot 15 so that the T-block 16 can be inserted into the T-slot 15. A clamping ball 17 is fixedly arranged on the outer side of the T-block 16. A clamping hole 18 is arranged in the T-slot 15. The clamping ball 17 is matched with the clamping hole 18.
[0025] Insert the T-block 16 into the T-slot 15, and insert the locking ball 17 into the locking hole 18, so that the T-block 16 can be locked, thereby fixing the fixing belt 2, and the fixing belt 2 is pulled outward to drive the T-block 16 to move outward, so that the locking ball 17 is separated from the locking hole 18, and the fixing belt 2 can be removed;
[0026] The adjustment component includes an adjustment box 3, a rotating column 5 and a double-groove pulley 6. A support plate 19 is hingedly provided on the inner side of the adjustment box 3. A torsion spring is provided at the connection between the support plate 19 and the adjustment box 3. The torsion spring can drive the support plate 19 to reset. The support plate 19 is arranged in an arc shape, so that the support plate 19 can better fit the back of the user's head, press the eye tracker body 1 tightly, and make the wearing more stable;
[0027] The outer ends of the two fixing belts 2 are respectively penetrated through the two ends of the adjusting box 3 for sliding arrangement, and the outer ends of the two fixing belts 2 are fixedly provided with a pull rope 4, and the rotating column 5 is rotatably arranged on the inner wall of the adjusting box 3, and the other end of the rotating column 5 penetrates the adjusting box 3 for rotation, and the double-groove pulley 6 is fixedly sleeved on the rotating column 5, and the other ends of the two pull ropes 4 are respectively fixedly arranged in the two grooves of the double-groove pulley 6, and the two pull ropes 4 are respectively wound in the two grooves of the double-groove pulley 6, and the winding directions of the two pull ropes 4 are the same, so that when the double-groove pulley 6 rotates, the two pull ropes 4 can be tightened and loosened at the same time, and a turning handle 7 is fixedly arranged on the outer side of the outer end of the rotating column 5, and the rotating column 5 can be driven to rotate by rotating the turning handle 7, and a slide groove 8 is arranged in the rotating column 5, and a positioning component is arranged in the slide groove 8;
[0028] The positioning assembly includes a pressing column 9, a movable plate 10, a spring 11 and two clamping columns 12. The pressing column 9 is slidably arranged in the slide groove 8. Adjustment holes are provided on both sides of the slide groove 8. The movable plate 10 is slidably arranged through the two adjustment holes. The inner end of the pressing column 9 is rotatably arranged on the movable plate 10. The two ends of the spring 11 are respectively fixedly arranged on the inner bottom of the slide groove 8 and one side of the movable plate 10. The two clamping columns 12 are respectively fixedly arranged at both ends of one side of the movable plate 10. A plurality of through holes 13 are provided through one side of the adjustment box 3.
[0029] The bottoms of the two clamping columns 12 are both arranged in an inclined surface, and the inclined surfaces of the bottoms of the two clamping columns 12 are arranged oppositely. A plurality of through holes 13 are evenly distributed on the circumference. The two clamping columns 12 and the plurality of through holes 13 are arranged in coordination, so that when the rotating column 5 rotates, the plurality of through holes 13 can squeeze the inclined surfaces of the two clamping columns 12 and push the two clamping columns 12 to one side. The spring 11 can drive the two clamping columns 12 to reset through the movable plate 10 and snap into the corresponding through holes 13.
[0030] The detailed working process of the utility model is as follows:
[0031] When wearing, the user first wears the eye tracker body 1 on the eyes, passes the head through the two fixing belts 2, and then turns the handle 7 to drive the double-groove pulley 6 to rotate through the rotating column 5. The double-groove pulley 6 rotates to shrink the two pull ropes 4, drive the two fixing belts 2 to be tightened, and at the same time drive the support plate 19 to be tightly fixed to the back of the user's head; at the same time, the rotating column 5 drives the two clamping columns 12 to rotate through the movable plate 10, and the plurality of through holes 13 can squeeze the inclined surfaces of the two clamping columns 12 to push the two clamping columns 12 outward, so that the two clamping columns 12 can circulate in the plurality of through holes 13, and when the two clamping columns 12 are reversed, the corresponding through holes 13 can hold the two clamping columns 12 for positioning, thereby preventing the rotating column 5 from reversing, thereby preventing the two fixing belts 2 from loosening;
[0032] When taking off, the user pushes the pressing column 9 inward, and drives the two clamping columns 12 to move outward through the movable plate 10 and separate from the corresponding through holes 13, so that the two fixing belts 2 are reset under the action of their own elastic force. The two fixing belts 2 drive the double-groove pulley 6 to rotate in the opposite direction through the two pull ropes 4, and the user's belt can be released.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
