The fixing plates 42 are axially symmetrically provided with a sliding groove 43 on the side close to the baffle 41. The sliding plate 44 is rotatably connected to the fixing rod 46 at one end away from the sliding plate 44. The sliding groove 43 provided in the fixed plate 42 moves the sliding plate 44 laterally toward the direction close to the slot 31. The movement of the sliding plate 44 drives the baffle 41, the rotating rod 45 and the fixed rod 46 to move toward the direction close to the slot 31 until the baffle 41 is moved to directly below the slot 31.

The upward movement of the positioning block 7 will drive the fixing rod 46 to move upward, and the rotating rod 45 will also rotate accordingly, so that the baffle plate 41 moves vertically upward to block the notch 31. Similarly, when there is no need to block the notch 31, the sliding plate 44 is moved in the opposite direction, the positioning block 7 will move from the vertical groove 62 to the transverse groove 61, the rotating rod 45 will rotate in the opposite direction, and the baffle plate 41 will move vertically downward and then move horizontally to the initial position.

The rotation of the rotating shaft 10 drives the first gear 11 to rotate, thereby driving the first rack 9, the connecting plate 8 and the sliding plate 44 to move toward the slot 31. The movement of the sliding plate 44 drives the moving rod 55 and the second rack 56 to move, thereby rotating the second gear 54 and the vertical rod 51. Since the vertical rod 51 and the sleeve 52 are threadedly connected, the vertical rod 51 The rotation of the sleeve 52 and the lens 2 will drive the sleeve 52 and the lens 2 to move into the shell 3 so that the lens 2 is released from the slot 31, and the limit rod 53 will move downward accordingly.

When the lens 2 is not needed, the round rod 12 can be rotated one hundred and eighty degrees. The rotation of the round rod 12 in the groove 33 will drive the filter plate 14 and the partition 13 to exchange positions so that the partition 13 is located at the through hole 32 to block the through hole 32, thereby preventing dust from entering the shell 3 through the through hole 32. In this step, the filter plate 14 and the partition 13 are driven to exchange positions by the rotation of the round rod 12, which can dissipate heat when the lens 2 is working and block dust when the lens 2 is not working.

[0035] See also Figure 4 , Figure 8 and Fig.10 As shown, in the present embodiment, preferably, the other end of the round rod 12 movably passes through the inner wall on the other side of the groove 33 and the end of the round rod 12 on this side is located inside the shell 3, and a third gear 15 is fixedly provided at one end of the round rod 12 away from the partition 13, and a third rack 16 is fixedly provided on one side of the moving rod 55, and the third gear 15 is meshed with the third rack 16 for transmission; when the sliding plate 44 moves back and forth laterally to realize the blocking or unblocking of the notch 31 by the baffle 41, it will also drive the moving rod 55 to move back and forth laterally, and the movement of the moving rod 55 will drive the third rack 16 to move, thereby realizing the rotation of the third gear 15 in both directions, and the rotation of the third gear 15 in both directions will drive the round rod 12 to rotate in two opposite directions, thereby realizing the replacement of the partition 13 and the filter plate 14, so that the filter plate 14 is located at the through hole 32 when the lens 2 is working, and the partition 13 is located at the through hole 32 when the lens 2 is not working.

Too much dust accumulation on the filter plate 14 will affect the heat dissipation effect. The cross bar 18 can be rotated. The rotation of the cross bar 18 drives the cam 19 to rotate. The rotation of the cam 19 drives the circular groove 191 to rotate, so that the limit block 20 can reciprocate up and down. The up and down reciprocating movement of the limit block 20 will drive the push rod 21 to reciprocate up and down along the limit plate 22. During the movement of the push rod 21, the ring 17 will collide with the ring 17, causing the ring 17 to vibrate slightly. The vibration of the ring 17 can make some dust on the filter plate 14 or the partition 13 fall into the dust collecting frame 23 at the bottom of the groove 33. When a lot of dust is collected in the dust collecting frame 23, it can be concentrated and cleaned.

[0039] The working principle of the present invention is: rotate the rotating shaft 10, the rotation of the rotating shaft 10 drives the first gear 11 to rotate, the rotation of the first gear 11 will drive the first rack 9 to move horizontally, the positive and negative rotation of the first gear 11 will drive the first rack 9 to move horizontally in two directions, the horizontal movement of the first rack 9 will drive the connecting plate 8 to move horizontally, thereby driving the sliding plate 44 to move in a direction close to the slot 31 or away from the slot 31. When the slot 31 needs to be blocked, the lens 2 is located in the slot 31 at this time, and the rotating shaft 10 is rotated. The rotation of the rotating shaft 10 drives the first gear 11 to rotate, thereby driving the first rack 9, the connecting plate 8 and the sliding plate 44 to move in a direction close to the slot 31, and the movement of the sliding plate 44 drives the moving rod 55 and the second rack 56 move to rotate the second gear 54 and the vertical rod 51. Since the vertical rod 51 and the sleeve 52 are threadedly connected, the rotation of the vertical rod 51 will drive the sleeve 52 and the lens 2 to move toward the inside of the shell 3, so that the lens 2 and the slot 31 are released, and the limit rod 53 also moves downward. The limit rod 53 is slidably connected to the inside of the shell 3 to prevent the sleeve 52 from rotating with the rotation of the vertical rod 51. The sliding plate 44 is continuously moved, and the second rack 56 will continue to mesh with the second gear 54 until the sleeve 52 drives the lens 2 to move to the lowest point. The second rack 56 is no longer meshed with the second gear 54. At this time, the lens 2 no longer moves further, and the baffle 41 moves to the side of the slot 31 and the height of the baffle 41 is higher than the lens 2. Continuing to move the sliding plate 44 will drive the baffle 41 to move below the notch 31, and the baffle 41 will be driven upward to block the notch 31 under the action of the vertical slot 62 and the positioning block 7. Similarly, when it is no longer necessary to block the notch 31, the reverse rotation of the rotating shaft 10 can cause the sliding plate 44 to move in the opposite direction, thereby driving the baffle 41 to move downward and then move in the opposite direction horizontally. Subsequently, the second rack 56 engages with the second gear 54 to drive the sleeve 52 and the lens 2 to move in the direction of the notch 31 and engage with the notch 31. At this time, the lens 2 can shoot the outside world. At the same time, the sliding plate 44 moves back and forth horizontally to achieve the baffle 41 blocking or releasing the notch 31, and it will also drive the moving rod 55 to move back and forth horizontally. The movement of the moving rod 55 will drive the third rack 1 6 moves to realize the rotation of the third gear 15 in both positive and negative directions. The rotation of the third gear 15 in both positive and negative directions will drive the round rod 12 to rotate in two opposite directions to realize the replacement of the partition plate 13 and the filter plate 14. It can be realized that when the lens 2 is working, the filter plate 14 is located at the through hole 32, and when the lens 2 is not working, the partition plate 13 is located at the through hole 32. The round rod 12 will reciprocate 180 degrees driven by the third rack 16 and the third gear 15. The rotation of the round rod 12 will drive the cross bar 18, the filter plate 14, the partition plate 13 and the fourth gear 24 to reciprocate. During the rotation of the fourth gear 24, it will mesh with the fifth gear 25, so that the fourth gear 24 rotates and then drives the cross bar 18 to rotate. The rotation of the cross bar 18 can realize the reciprocating impact of the top rod 21 on the ring 17.This causes some dust on the partition plate 13 and the filter plate 14 to fall off.
