[0002] Currently, many studies have shown that intense pulsed light and laser systems are one of the most effective physical therapies for meibomian gland dysfunction and its related dry eyes. The treatment heads are divided into large and small types, which need to be switched back and forth according to different treatment needs. However, the optical head is made of sapphire material and its surface is very smooth. If medical staff simply use their fingers to disassemble it, it takes a lot of effort to clamp it and remove it from the slot. For this reason, a light guide head extractor is designed to solve the problem that medical staff currently have a lot of trouble in extracting and replacing light guide heads. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions: an optical head extractor comprises a main body 1, a movable plate 4, a rubber pad 3 and a transmission shaft 8, a transmission shaft 8 is provided through the middle of the inner wall of the main body 1, and movable plates 4 are slidably provided on both sides of the outer wall of the main body 1, the movable plate 4 is a U-shaped plate, and the rubber pad 3 is installed on the end surface of the movable plate 4, rotating disks 7 are installed at both ends of the transmission shaft 8, the rotating disk 7 is movably connected to the movable plate 4, the transmission shaft 8 is used to control the distance between the two movable plates 4, and the side wall of the rotating disk 7 is symmetrically installed with a second connecting rod 9, the movable plate 4 is movably connected to the movable plate 4, and the transmission shaft 8 is used to control the distance between the two movable plates 4. The first connecting rods 2 are symmetrically installed on the upper parts of the outer walls of the movable plate 4, and a connecting plate 6 is arranged between the movable plate 4 and the rotating disk 7. The first connecting rod 2 and the second connecting rod 9 are respectively penetrated at both ends of the connecting plate 6. A movable groove 12 is opened in the center of the top of the main body 1, and the transmission shaft 8 is penetrated inside the movable groove 12. A transmission rod 10 is arranged on one side of the middle part of the transmission shaft 8. The transmission rod 10 is inclined, and the end of the transmission rod 10 extends to the outside of the movable groove 12. A fixed rod 11 is installed on the top of the main body 1 and next to the movable groove 12.

[0020] Through the above technical solution: when in use, the distance between the fixed rod 11 and the transmission rod 10 is shortened by holding, and the rotation of the transmission rod 10 synchronously drives the transmission shaft 8 to rotate, and while the transmission shaft 8 rotates, it synchronously drives the movable plate 4 to slide inward under the main body 1 through the rotating disk 7 and the connecting plate 6, forcing the surface of the rubber pad 3 to contact with the optical head and clamp the optical head. At this time, the operator only needs to apply an upward force to force the main body 1 to move horizontally upward while clamping the optical head, and use the rubber pad 3 to increase the contact area and static friction with the optical head, so that the optical head can be pulled out while improving the force effect, thereby solving the problem that it is more laborious for medical staff to pull out and replace the optical head.

[0021] See also Figure 1-Figure 4As shown, a groove is provided on the surface of one side of the transmission rod 10 away from the fixed rod 11, and a spring is arranged inside the movable groove 12. The two ends of the spring are respectively connected to the side wall of the transmission rod 10 and the inner wall of the movable groove 12, and auxiliary strips 5 are symmetrically installed on the lower part of the outer wall of the main body 1, and positioning strips 13 are symmetrically installed on both sides of the inner wall of the movable plate 4. The positioning strips 13 are located above the auxiliary strips 5, and the surface of the positioning strips 13 is in contact with the surface of the auxiliary strips 5. A fixed plate 14 is installed on one end surface of the two movable plates 4, and the fixed plate 14 is located next to the rubber pad 3, and elastic plates are installed on the surface of the fixed plate 14 at equal intervals. A through hole is relatively opened on the end surface of the other movable plate 4, and the through hole is flush with the fixed plate 14.

[0022] The above technical scheme: during the sliding of the movable plate 4, the positioning bar 13 slides synchronously on the upper part of the auxiliary bar 5. Since the positioning bar 13 and the auxiliary bar 5 are in contact with each other and remain parallel, the movable plate 4 always remains in a vertical state with the main body 1, ensuring that the surface of the rubber pad 3 is fully in contact with the optical head, and the static friction between the rubber pad 3 and the optical head is increased to the maximum extent. At the same time, the sliding of the movable plate 4 also drives the fixed plate 14 to drive the elastic plate to pass through the through hole to penetrate another movable plate 4, and the elastic plate is used to cooperate with the optical head to limit the distance between the movable plates 4, so as to prevent the problem of the rubber pad 3 and the optical head being out of contact during the disassembly process, thereby achieving the purpose of convenient disassembly. In the clamping process, the operator's fingers are embedded in the grooves through the grooves, so as to reduce the problem of fingers slipping on the transmission rod 10 and the fixed rod 11 when pulling out. The setting of the spring enables the transmission rod 10 to reset itself under the action of elastic force after the restriction of the fixed plate 14 is released, so that the movable plate 4 remains in the open state for a long time for subsequent use.
