[0038] Example 2

[0039] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 The protection component 5 includes a protection plate 51 slidably installed at the middle of the front side of the mounting shell 3 and an n-shaped plate 52 arranged at the front side of the protection plate 51. The rear side of the n-shaped plate 52 is fixedly installed on the mounting shell 3, and a positioning rod 53 is slidably installed through the middle of the n-shaped plate 52. A pulling plate 54 is fixedly installed at the front end of the positioning rod 53, and the position of the protection plate 51 can be adjusted, thereby protecting the front side of the multi-spectral camera body 4.

[0040] Positioning grooves 511 are respectively provided near the middle and the top of the front side of the protection plate 51, and the output end of the pulling plate 54 is inserted into the inner cavity of the positioning groove 511 below, which is conducive to the positioning work.

In addition, when the L-shaped clamping plates 67 move in the opposite direction, they will drive the adjacent trapezoidal blocks 672 to move in the opposite direction through the adjacent fixed plates 671, so that they can move away from the adjacent squeezing balls 673. In addition, the connecting plate 68 and the sliding plate 69 will move upward and recover under the action of the rebound force of the reset spring C693. At this time, the sliding plate 69 will move to the inner cavity of the mounting shell 3, and then the multi-spectral camera can be installed. The multi-spectral camera body 4 is placed in the middle of the bottom of the mounting shell 3. After the placement is completed, the pushing plate 61 can be released. At this time, the L-shaped clamping plates 67 on both sides will move relatively, thereby supporting the bottom of the multi-spectral camera body 4. In addition, the sliding plate 69 will also move downward to achieve the partition of the front and rear sides of the multi-spectral camera body 4, thereby completing the clamping installation of the multi-spectral camera body 4. When the multi-spectral camera body 4 is not in use, the pulling plate 54 can be pulled forward to drive the positioning rod 53 to move forward, thereby moving away from the inner cavity of the lower positioning groove 511, and at the same time, the return springs A522 on both sides will be stretched, and then the protective plate 51 is moved downward to the front side of the multi-spectral camera body 4 to protect it. Then, the pulled pulling plate 54 can be released to restore it under the action of the rebound force of the return spring A522, thereby inserting it into the inner cavity of the upper positioning groove 511 to position the protective plate 51.
