Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0022] Embodiment:

[0023] Please refer to Figure 1 - Figure 4 The optical axis device with self-lubricating function in the embodiment comprises an optical axis shell 1, an optical axis inner core 2 is arranged on the inner side of the optical axis shell 1, a groove is formed on the inner side of the optical axis shell 1, a plurality of sliding holes are formed on the inner side of the groove, a plurality of plug blocks 3 are slidably connected to the inner side of the sliding holes, a plurality of insertion grooves matched with the plug blocks 3 are formed on the inner side of the optical axis inner core 2, the outer sides of the plurality of plug blocks 3 are movably inserted into the inner sides of the corresponding insertion grooves, a plurality of first springs 4 are fixedly connected to the other sides of the plurality of plug blocks 3, the other ends of the plurality of first springs 4 are fixedly connected to one side of the groove, and two first blocks 7 are slidably connected to the inner side of the groove.

[0024] When the optical axis inner core 2 reaches the appropriate position, the plug blocks 3 enter the inner side of the optical axis inner core 2 under the extrusion of the first springs 4, then the user no longer drives the third blocks 9, the second springs 6 are compressed at this time, the first blocks 7 are reset and abut against the outer sides of the plug blocks 3, and the fixing between the optical axis inner core 2 and the optical axis shell 1 is completed.

[0025] The other sides of the two first blocks 7 are fixedly connected with second blocks 8, the sides away from each other of the two first blocks 7 are fixedly connected with third blocks 9, the one sides of the plurality of first blocks 7 are fixedly connected with a plurality of second cylinders 13, the inner sides of the plurality of second cylinders 13 are slidably connected with a plurality of second rods 14, the one sides of the plurality of second rods 14 are fixedly connected with a plurality of connecting blocks, the one sides of the plurality of connecting blocks are fixedly connected to the inner wall of one side of the groove, the one sides of the plurality of connecting blocks are fixedly connected with a plurality of second springs 6, and the other ends of the plurality of second springs 6 are fixedly connected to the one sides of the corresponding first blocks 7, so that the first blocks 7 can be reset.

[0026] A plurality of first rods 12 are fixedly connected to one side of the groove, the outer sides of the plurality of first rods 12 are slidably connected with a plurality of first cylinders 11, the one sides of the plurality of first cylinders 11 are fixedly connected to the one sides of the corresponding plug blocks 3, two screw grooves are formed on the inner side of the optical axis shell 1, and two connecting covers 10 are threadedly connected to the inner sides of the two screw grooves, and the one sides of the two connecting covers 10 are fixedly connected with protective pads, which can protect the mechanism.

[0027] The optical axis shell 1 is internally provided with two buckle grooves, and the two buckle grooves are slidably connected to the outer side of the third block 9, and the surface of the optical axis shell 1 is sprayed with a PTFE coating, so that the device has a self-lubricating function.

[0028] The working principle of the above embodiment is as follows:

[0029] In use, the surface of the optical axis shell 1 is sprayed with a PTFE coating, and when the optical axis shell 1 is externally provided with a sliding block, the sliding block is continuously moved, which causes the inner side of the sliding block to continuously rub against the outer side of the optical axis shell 1. When the sliding block rubs, the PTFE coating slowly falls off and forms a lubricating layer on the contact surface, thereby helping the device to automatically lubricate. When installing the optical axis inner core 2, the user can first use his fingers to move the third block 9 in the buckle groove, and then directly insert the optical axis inner core 2 into the inner side of the optical axis shell 1. At this time, the outer side of the optical axis inner core 2 will extrude the insertion block 3 and the first spring 4. When the optical axis inner core 2 reaches the appropriate position, the insertion block 3 enters the inner side of the optical axis inner core 2 under the extrusion of the first spring 4. Then the user no longer moves the third block 9, and the second spring 6 is compressed at this time. At this time, the first block 7 is reset and abuts against the outer side of the insertion block 3. At this time, the fixing between the optical axis inner core 2 and the optical axis shell 1 is completed, which enables the user to quickly complete the disassembly and installation work. Then the connecting cover 10 on both sides is tightened with the optical axis shell 1.
