The working principle is as follows: when the supporting device for ophthalmic care needs to be installed, firstly, the position of the fixing frame 3 is adjusted according to the width of the installation position;
by rotating the rocking handle 6, the rocking handle 6 drives the screw rod 15 in the main frame body 1 to rotate, and the screw rod 15 drives the sliding frame 2 to slide in the main frame body 1 under the action of the threads;
when the fixing frame 3 is adjusted to a proper position, the fixing frame 3 is clamped on the mounting position, and the compression bolt 4 on one side of the fixing frame 3 is rotated, so that the compression bolt 4 drives the compression block 5 to fix the fixing frame 3;
when the front and back positions of the lifting block 14 need to be adjusted, the longitudinal slide blocks 24 on the lower sides of the two ends of the sliding beam 9 drive the limiting balls 23 in the sliding beam 9 to move by pushing or pulling the sliding beam 9;
the limiting ball body 23 moves in the longitudinal rail 7, so that the limiting ball body 23 enters the limiting grooves 25 at different positions in the longitudinal rail 7, and the front and rear positions of the lifting block 14 are adjusted and automatically limited;
when the height of the lifting block 14 needs to be adjusted, the push block 10 in the middle of the front end of the sliding beam 9 is pressed, so that the push block 10 drives the sliding plate 30 in the sliding beam 9 to move backwards;
the sliding plate 30 moves backwards to separate the clamping block 31 from the square groove on the lifting block 16, and the transverse rail 11 moves upwards under the action of the elastic force of the auxiliary adjusting spring 18;
when the transverse rail 11 is pressed downwards, the transverse rail 11 drives the lifting block 16 to move downwards, and when the lifting block 14 is adjusted to a proper position, the push block 10 is released;
under the action of the elastic force of the second return spring 32, the sliding plate 30 moves towards the front end, so that the fixture block 31 is clamped with the square groove on the lifting block 16 to limit the position of the lifting block 16;
when the horizontal position of the lifting block 14 needs to be adjusted, the push rod 21 on the horizontal sliding block 12 is pressed, and the push rod 21 drives a shaft on one side of the push rod to move in a straight notch arranged on the driving block 27;
the driving block 27 moves towards the inside of the transverse sliding block 12, and the driving block 27 moves to drive the positioning rod 28 to be separated from the positioning rack 26, so that the transverse sliding block 12 can slide on the transverse track 11, and the transverse position of the lifting block 14 can be adjusted;
when the transverse position of the lifting block 14 is adjusted to a proper position, the driving block 27 is reset under the action of the elastic force of the first return spring 29 by releasing the push rod 21;
the driving block 27 drives the positioning rod 28 to enter the positioning rack 26, so that the transverse position of the lifting block 14 is automatically limited;
after the lifting device is adjusted, the medical staff can lift the arms of the medical staff by preventing the arms from entering the grooves of the lifting block 14, so that the medical staff is prevented from shaking the treatment arms for a long time;
in the lifting process, the medical staff can rotate the arm according to the requirement, so as to drive the lifting block 14 to synchronously rotate on the transverse sliding block 12, so as to meet the operation requirement of the medical staff, and the content which is not described in detail in the specification belongs to the prior art which is well known by the professional in the field.
