The edges and corners of each part are in arc transition, the structure design can avoid the eyelid hook from scratching or hurting the human body, meanwhile, the upper surface of the guide part is provided with the inclined guide surface 68, so that the eyelid hook can be conveniently inserted into the lower surface of the eyelid, and the eyelid can be unfolded to be operated more easily.

The working beam is slidably mounted between the two side beams, and the specific structure may be that a slideway 69 is correspondingly arranged on the inner sides of the left and right side beams, and two ends of the working beam are respectively slidably mounted in the slideway. For example, a feeding driving mechanism is arranged between the front frame and the working beam on the corresponding side, and between the rear frame and the corresponding working beam, and the working beam is fixed by the feeding driving mechanism 70, so that the working beam cannot move randomly in use. In general, the feed drive mechanism may be a pneumatic or electric cylinder, the cylinder rod of which is extended or retracted so that the work beam has at least two defined positions.

Generally, when the eyelid is in a state in which it is opened, the cylinder rod of the feed drive mechanism is in a retracted state, and when the eyelid needs to be appropriately released, the cylinder rod is controlled to extend. When necessary, the feed driving mechanism can be controlled to drive the working beam to move for a certain distance, and the moving distance is required to ensure that the eyelid is not separated from the eyelid hook, so that the operation can effectively relieve eye fatigue, and the feed driving mechanism also has a good relieving effect on relieving the internal stress of a patient.

It should be noted that the lid hook does not disengage from the lid when the cylinder rod is extended, only a "loose" effect, i.e. only a proper relaxation of the lid, and typically the cylinder rod travel may be 0.5-2 mm. Of course, the feed drive mechanism may also take other forms, and may be capable of positioning two determined positions. The feeding and the returning of the feeding driving mechanism can realize the adjustment of the distance between the upper eyelid hook and the lower eyelid hook and the adjustment of the opening and closing range of the upper eyelid and the lower eyelid, thereby achieving the function of relaxing eyes, and the next treatment can be continued after the feeding driving mechanism is restored to the original state.

Transition section of thick bamboo inner wall is equipped with holding tank 71, and locking Assembly includes that briquetting 72 and briquetting go up connecting draw and drag pole 73, and the briquetting is installed in the holding tank, draws the pole and wears out the one end of transition section of thick bamboo outward and is equipped with grab handle 74 to the cover is equipped with spring 75 drawing the pole on dragging, and this spring one end supports the briquetting towards the one end of grab handle, and the other end supports and holds tank bottom 76, when drawing the pole to the outside pulling, leans on the elasticity of spring to compress tightly the briquetting on the working lever, with the removal on the restriction working lever height position.

For improving stability, be equipped with a plurality of anti-skidding lines on the briquetting towards a working rod side end face, be equipped with at a working rod towards briquetting a side surface with anti-skidding line complex stria 77, during the design stria structure, can adopt the structure similar to the tooth, fix through frictional force between anti-skidding line and the stria. When the anti-skidding lines adopt horizontal lines, even mutual occlusion between the anti-skidding lines and the cross lines can be realized, and the distance between the cross lines (and the anti-skidding lines) is very small, so that the eyelid hook can be finely adjusted in height position, and the eyelid hook can be well guaranteed to be adjusted to an ideal working position. When the pulling rod is pulled outwards to enable the pressing block to release the positioning of the working rod, the working rod can slide up and down along the inner cavity of the transition cylinder to adjust the position, and the purpose of adjusting the height of the eyelid hook is achieved.

In an alternative embodiment, the brake sleeve comprises a sleeve 78 and a lifting rod 79 symmetrically arranged outside the sleeve, grooves matched with the lifting rod are respectively arranged on the upper end surface of the base seat, the tail end of the lifting rod extends out of the base seat, limiting seats 80 are arranged on two sides of the base seat corresponding to the lifting rod, the limiting seats and the lifting rod are tensioned through tensioning pieces 81, and springs are usually adopted as the tensioning pieces. Through the elastic acting force of the tensioning piece, the lifting rod is guaranteed to be stably matched with the groove on the upper end face of the base seat and cannot be separated.

It should be noted that, a transition section of thick bamboo is connected with rotating between the base seat to no displacement in the axial direction is guaranteed, as an example, can set up slider 82 on the transition section of thick bamboo outer wall, be equipped with the annular along the horizontal direction at the mounting hole inner wall of base seat, slider and annular cooperation, can guarantee transition section of thick bamboo and base seat normal running fit simultaneously, can also prevent transition section of thick bamboo axial float in the base seat.

In the use, only when pulling upward the lifting rod manually, the brake sleeve just has the ascending effort of axial direction, and in addition, the brake sleeve does not have axial effort, consequently, the tensioning piece need not to provide great effort, can be stable keep the brake sleeve position, and structural design guarantees easily. It should be noted that the specific structure of the braking sleeve can be as follows: the inner wall of the sleeve body is provided with a plurality of matching teeth along the circumferential direction, the outer wall of the upper end of the transition cylinder is provided with a tooth structure matched with the transition cylinder, and when the lifting rod is lifted, the brake sleeve is separated from the transition cylinder to remove the matching with the transition cylinder.

After the transition cylinder (eyelid hook orientation) is adjusted by rotation, the lifting rod is loosened slightly, the lifting rod tends to restore to the original position under the acting force of the tensioning piece, and at the moment, the matching teeth on the brake sleeve are matched with the teeth at the corresponding positions of the tooth structure of the transition cylinder until the lifting rod restores to the original position under the acting force of the tensioning piece (namely, the lifting rod is matched with the groove at the upper end of the base again), so that the rotation adjustment operation of the transition cylinder is completed. It should be noted that the eyelid hook position and orientation adjustment is usually fine adjustment, and the large adjustment is performed by moving and adjusting the main frame as a whole, so that the length of the matching part of the working rod and the transition cylinder does not need to be too long, and the adjustment and use requirements can be met.

In an optional embodiment, the working rod is provided with the recessed portion 83 towards one side of the accommodating groove, and the surface of the recessed portion is provided with anti-skid lines, so that the structural design can effectively ensure the smooth sliding fit between the main body portion of the working rod and the inner wall of the transition cylinder, and can also ensure the fixing requirement between the working rod and the pressing block, and the lines on the surface of the pressing block are matched with the cross lines in the recessed portion, so that the working rod can be fixed. The length of the concave part used for being matched with the pressing block on the working rod is smaller than that of the transition cylinder, and on the basis that the sliding fit of the working rod and the transition cylinder is guaranteed, the fixing effect of the working rod and the pressing block in a matched mode can be guaranteed.

When the eyelid retractor is used for adjusting the position of an eyelid hook, one hand can operate the lifting rod on the brake sleeve to lift the lifting rod upwards for releasing the limit of the brake sleeve on the circumferential direction of the transition cylinder, and meanwhile, the other hand synchronously operates the pulling rod on the transition cylinder for releasing the limit of the pressing block on the height direction of the working rod, so that the height and the orientation of the eyelid hook can be adjusted to meet the requirement of opening the eyelid.

According to the use requirement, the orientation or the height of the eyelid hook can be adjusted independently, and the orientation and the height of the eyelid hook can be adjusted synchronously. As an example, the operation of synchronously adjusting the orientation and height of the eyelid hook may be: the thumb of one hand presses the pressure handle 89 of work lever upper end, the forefinger holds in the palm and presses the handle lower extreme, and the third finger and the middle finger of this hand upwards hook the lifting rod of braking cover both sides respectively, and carry out the lifting action, make the lifting rod break away from basic seat upper end recess, meanwhile, the pull pole is drawn in the outside pulling of another hand, it drives the briquetting and removes to the tank bottom of holding tank to draw the pole, relieve the spacing to the vertical direction of work lever, at this moment, only need upwards or downward advantage of the gesture adjustment work lever position for that hand of operation lifting rod, adjustment eyelid hook height that can relax, because thumb and forefinger have already pinched the pressure handle, consequently, the work of adjustment work lever height realizes more easily. In conclusion, the eyelid hook orientation and height adjustment can be performed synchronously, and a doctor can perform adjustment operation, so that the labor amount of manpower is reduced, and the eyelid hook is very convenient.

The xarm can be fixed on the sliding seat by the locking subassembly, locking subassembly can be referred to the structure of locking subassembly part, namely, set up the recess in the sliding seat hole, install the briquetting in the recess, can drag through one and drag the piece and mention the briquetting, remove and press from both sides tight fixed action to the xarm, and when loosening and drag the piece, the briquetting is pushed down the xarm surface, guarantee that the xarm axial no longer moves, the xarm corresponds the briquetting and is equipped with anti-skidding line, the briquetting is lifted and can be realized breaking away from between the xarm, equally, the position that the xarm corresponds the sliding seat recess can set up the depressed part, set up the line with briquetting complex on the depressed part surface. By means of the structural design, the cross arm can be axially adjusted as required, the distance between the base seat and the sliding seat is further adjusted, and the distance between the upper eyelid hook and the lower eyelid hook is adjusted.

In an alternative embodiment, in order to improve the stability of the sliding seat, an upright plate 85 is disposed on the lower side of the sliding seat, a fixing member 86 is mounted on the upright plate, and after the sliding seat is adjusted to a desired position, the sliding seat and the working beam are fixed by the fixing member. By way of example, the fastener may be a screw, and the slide mount may be held in a desired position by tightening the screw with the end of the screw against the side wall of the work beam.

It should be pointed out again that, because the force of the eyelid of the human body is small and there is no large load in the operation of the mechanical equipment, the limit, position and fixed connection parts of the invention can meet the requirement of stability by the friction force between the parts, and the condition of failure caused by the eye closing action of the patient is avoided, and the stability of the fixed structure parts is guaranteed.
