Referring to fig. 2, for the present invention provides a high strength connection structure of lens cone and lens base, including lens cone 1, lens base 2, and screens dish 3, lens base 2 includes upper cover 21 and lower cover 22. The clamping disk 3 is arranged in the lens base 2 and on the inner wall of the upper cover 21. The clamping plate 3 shown in fig. 3 is provided with a plurality of clamping legs, each clamping leg comprises a first clamping leg 31 and two second clamping legs 32, and the first clamping leg 31 and the second clamping leg 32 are respectively arranged at two ends with longer length on the same side of the clamping plate 3, and can also be arranged at two ends with shorter length. The lengths of the first clamping leg 31 and the second clamping leg 32 are both larger than the lengths of the first clamping leg 31 and the second clamping leg 32 in the background technology, and the length of the excess length is equal to the thickness of the upper cover 21. The upper cover 21 is provided with a first hole site 211 and a second hole site 212 for the first clamping pin 31 and the second clamping pin 32 to pass through. The bottom end of the lens barrel 1 is provided with a first clamping hole 11 and a second clamping hole 12 corresponding to the first clamping pin 31 and the second clamping pin 32.

With reference to fig. 2 and 3, one first clamping leg 31 and two clamping legs are arranged according to three vertexes of an isosceles triangle, and the first clamping leg 31 is a vertex. The side surfaces of the first clamping pin 31 and the second clamping pin 32, which are deviated from each other, are respectively provided with a first clamping hook 311 and a second clamping hook 321. The top surface of the first clamping hook 311 is arranged downwards along the direction far away from the first clamping pin 31. The second hook 321 is divided into two parts, namely a straight end 3211 connected with the second hook 32, and an inclined end 3212 connected with the straight end 3211 and far away from the second hook 32, wherein the top surface of the inclined end 3212 is arranged in a downward inclination manner along the direction far away from the straight end 3211. Because of the straight end 3211, the second clip 32 and the second clip hole 12 can be pre-installed before use, and then aligned with the first clip 31 and the first clip hole 11, and the first clip 31 is clipped on the first hole 211 by the inclined surface of the first clip 31, thereby completing the assembly of the lens barrel 1 and the upper cover 21. The advantage is that the two pre-installed clamping feet 32 are beneficial to improving the stability of the lens barrel 1 during installation. And the straight end 3211 enables the lens barrel 1 to be mounted only in the above-described manner.
