[0033] Specifically, the limit slider 15 plays a fixing role on the pull rod 13, so that the limit slider 15 plays a limiting role in the limit groove 14 through the pull rod 13, so that the limit slider 15 moves along the inner wall of the limit groove 14, so that the other end of the pull rod 13 moves out of the inner wall of the card slot 17, and the connecting block 5 plays a fixing role on the rotating block 4. In this way, by moving the connecting block 5 and limiting the rotating block 4 in the circular rotating groove 6, the rotating block 4 can be driven to move along the inner wall of the circular rotating groove 6, so that the lens 3 in the lens barrel 2 is exposed, so that the lens 3 inside the lens barrel 2 can be disassembled and assembled, so that the lens 3 is conveniently cleaned.

[0034] Reference Figure 2 Figure 3 The defogger assembly includes a fixing groove 8, which is opened inside the sub-frame 7. A support rod 18 is fixedly connected to the inner wall of the fixing groove 8, and a heating wire 10 is fixedly connected to the other end of the support rod 18. A power source 11 is fixedly connected to the bottom of the sub-frame 7, and the top of the power source 11 is fixedly connected to the bottom end of the heating wire 10. A lens 3 is fixedly connected to the inside of the sub-frame 7, and a plurality of air outlet holes 9 are opened on the inner wall of the sub-frame 7.

[0035] Specifically, the bottom end of the heating wire 10 is connected to the power supply 11, so that by starting the power supply 11, the heating wire 10 generates heat and generates thermal energy, and the support rod 18 fixes the heating wire 10, so that the heating wire 10 is more stable when heating, and then under the action of the air outlet 9, the heat in the fixing groove 8 is transferred to the inside of the sub-frame 7, and then the heat is transferred into the lens barrel 2, so that the fog on the lens 3 in the lens barrel 2 is removed, so that the efficiency of the lens is improved when it is working.

[0036] Reference Figure 1 , Figure 3 and Figure 5 One end of the lens barrel 2 is fixedly connected to the main frame 1, and a window piece 19 is fixedly connected inside the main frame 1.

By providing anti-slip grooves on the side of the pull rod 13 away from the limit slider 15, the pull rod 13 can be more stable when being pulled.

[0038] Working principle: When it is necessary to defog the lens 3, the power supply 11 is turned on to make the heating wire 10 generate heat and generate thermal energy. Under the action of the support rod 18, the heating wire 10 is more stable when heating. Then, under the action of the air outlet 9, the heat is transferred to the inside of the sub-frame 7, and then the heat is transferred into the lens barrel 2. In this way, the lens 3 can be defogged for better shooting.

[0039] When the lens 3 needs to be replaced, the limit slider 15 is moved along the inner wall of the limit groove 14 through the pull rod 13, thereby squeezing or stretching the spring 16, so that the other end of the pull rod 13 moves on the inner wall of the card groove 17, and then by moving the connecting block 5, the rotating block 4 is synchronously driven to move along the inner wall of the circular rotating groove 6, so that the lens 3 inside the lens barrel 2 can be disassembled and assembled, so that the lens 3 can be cleaned or replaced more conveniently.
