[0028] Please refer to Figures 1-7An embodiment of this utility model provides a measuring tool for diplopia examination, including a fixed headband 3 and an adjuster 6. The adjuster 6 is movably fitted on the outer wall of the fixed headband 3. The fixed headband 3 is made of plastic. Angle scales are provided on both sides of the outer surface of the fixed headband 3 located on the adjuster 6. An installation block 1 is fixedly connected to the front end of the adjuster 6. An installation groove 2 is provided on the side of the installation block 1 away from the adjuster 6. Damping bearings 5 ​​are provided on both sides of the inner wall of the installation groove 2. A threaded sleeve 4 is rotatably connected between the damping bearings 5 ​​through a rotating rod. A screw 8 is threadedly connected to the inner wall of the threaded sleeve 4. A connecting rod 7 is fixedly connected to the end of the screw 8 away from the damping bearings 5. A diplopia reference object 11 is rotatably provided at the lower end of the connecting rod 7.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during use, when performing a diplopia test on a patient, the fixed headband 3 is placed on the patient's head. Then, rotating the connecting rod 7 adjusts the distance between the diplopia reference object 11 and the patient. With the help of the damping bearing 5, the threaded sleeve 4 can be rotated, thereby adjusting the height of the diplopia reference object 11. With the help of the damping bearing 5, the rotation can be stopped as soon as it is released, providing high flexibility. Then, the patient focuses on the diplopia reference object 11. When the diplopia reference object 11 seen by the patient's two eyes completely overlaps, the diplopia test is completed. At this time, the parameters of diplopia can be obtained by observing the rotation of the threaded sleeve 4 and the rotation of the screw 8 and comparing them with the pre-set data. The operation is simple and convenient.

[0030] The outer wall of the rear end of the double-view reference object 11 is provided with a second groove 13, and a second magnet 12 is installed inside the second groove 13. The surface of the connecting rod 7 is provided with a first groove 9 above the double-view reference object 11, and a first magnet 10 is installed inside the first groove 9. The second groove 13 and the second magnet 12 are both circular in shape, and the first groove 9 and the first magnet 10 are both circular in shape.

[0031] Specifically, such as Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, during use, when the double-view reference object 11 rotates, that is, when the first magnet 10 and the second magnet 12 come into contact, the magnetism generated by the first magnet 10 and the second magnet 12 can limit and fix the double-view reference object 11, thereby achieving the fit between the connecting rod 7 and the double-view reference object 11, and thus completing the storage of the double-view reference object 11.

[0032] Working principle: in the application, when the patient is examined for diplopia, the fixed head 3 is worn on the patient's head, and then the connecting rod 7 is rotated to adjust the distance between the diplopia reference 11 and the patient. The damping bearing 5 can be used to rotate the threaded sleeve 4, thereby adjusting the height position of the diplopia reference 11. The damping bearing 5 can be used to realize the rotation position loosening and stop, and the flexibility is strong. Then the patient gazes at the diplopia reference 11, and when the diplopia reference 11 viewed by the patient's eyes completely overlaps, the detection of diplopia is completed. At this time, the rotation of the threaded sleeve 4 and the rotation of the screw rod 8 can be observed, and the parameters of diplopia can be obtained by comparing the pre-data. The operation is simple and convenient. Secondly, when the diplopia reference 11 rotates, that is, when the first magnet 10 contacts the second magnet 12, the magnetic force generated by the first magnet 10 and the second magnet 12 can fix the limit of the diplopia reference 11, so as to realize the adhesion of the connecting rod 7 and the diplopia reference 11, and then complete the storage of the diplopia reference 11.
