[0023] Refer to Figures 1 - 4 , an optical imaging lens with good fixing effect, including a housing 1 and an optical imaging lens body 2. One end of the optical imaging lens body 2 is fixed with a plurality of first clamping blocks 4 by bolts. A first clamping groove 3 is formed on one side of the first clamping block 4. A circular ring 8 is rotatably connected to the outer wall of one side of the housing 1. One end of the optical imaging lens body 2 is butted against the housing 1, so that the first clamping block 4 enters the gap formed between a plurality of protrusions inside the circular ring 8. A plurality of third sliding grooves 12 are formed on the outer wall of one side of the housing 1. A second clamping block 10 is slidably connected in the third sliding groove 12, and the second clamping block 10 is clamped with the first clamping groove 3. A first spring 11 is welded to one side of the second clamping block 10, and the first spring 11 is fixed to the second clamping block 10. Continue to push the optical imaging lens body 2 inward, so that the first clamping block 4 contacts the housing 1, and then rotate the optical imaging lens body 2 to move the first clamping block 4, so that the inclined surface of the first clamping block 4 squeezes the second clamping block 10 to move along the third sliding groove 12, and the first spring 11 contracts until the positions of the first clamping groove 3 and the second clamping block 10 correspond to each other. At this time, the first spring 11 rebounds and elongates, so that the second clamping block 10 is clamped with the first clamping groove 3. A fixing component for restricting the rotation of the circular ring 8 is provided at the bottom of the housing 1.

[0024] In the present utility model, it should be noted that the fixing component includes a fourth chute 13 which is opened on the outer side of one side of the housing 1. A limiting ring is fixed inside the fourth chute 13 by bolts. A round rod 17 is arranged inside the limiting ring. A second spring 18 is sleeved on the outer side of the round rod 17, and both ends of the second spring 18 are fixed to the round rod 17 and the bottom of the fourth chute 13 respectively. An insertion opening 15 is opened at the bottom of the ring 8, and the round rod 17 is inserted into the insertion opening 15. A lever 16 is adhered to the outer side of the round rod 17. A sliding sleeve 14 is fixed to one side of the fourth chute 13 by bolts. A clamping groove is opened on one side of the sliding sleeve 14, and the position of the lever 16 is restricted by the clamping groove, so that the position of the round rod 17 after moving downward is fixed, and the lever 16 can be clamped with the clamping groove. Rotate the lever 16 to move it out of the clamping groove, and then push the lever 16 upward to move it upward along the fourth chute 13. The second spring 18 rebounds and elongates until the round rod 17 is inserted into the insertion opening 15, so that the position of the ring 8 is fixed. A plurality of second chutes 9 are opened on the outer wall of one side of the housing 1. A fixing rod 6 is slidably connected inside the second chutes 9. A plurality of first chutes 7 are opened inside the ring 8, and the fixing rod 6 passes through the first chutes 7. The first chutes 7 can guide the fixing rod 6 to move stably. One end of the optical imaging lens body 2 is rotatably connected with a protective cover 5. The protective cover 5 can protect the lens of the optical imaging lens body 2 to prevent it from being easily worn when exposed. A knob is adhered to one side of the ring 8.

[0025] Working principle: When the optical imaging lens body 2 needs to be installed, first dock one end of the optical imaging lens body 2 with the housing 1, so that the first clamping block 4 enters the gap formed between a plurality of protrusions inside the ring 8, and continue to push the optical imaging lens body 2 inward, so that the first clamping block 4 contacts the housing 1, and then rotate the optical imaging lens body 2 to move the first clamping block 4, so that the inclined surface of the first clamping block 4 squeezes the second clamping block 10 to move along the third chute 12, and the first spring 11 contracts until the position of the first clamping groove 3 corresponds to that of the second clamping block 10. At this time, the first spring 11 rebounds and elongates, so that the second clamping block 10 is clamped with the first clamping groove 3. Then rotate the lever 16 to move it out of the clamping groove, and then push the lever 16 upward to move it upward along the fourth chute 13. The second spring 18 rebounds and elongates until the round rod 17 is inserted into the insertion opening 15, so that the position of the ring 8 is fixed.

[0026] In addition, the terms "installation", "setting", "connection" and "sleeving" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present application according to specific situations.
