However, after the rotation and displacement adjustments are completed, the adjustment members cannot be fixed, so that the adjustment members rotate and move on their own, making it difficult to maintain the position state of the lenses after adjustment, affecting the maintenance of the light spot effect, inconvenient to use, and having certain limitations.

[0028] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: through the provided housing 1, when the user needs to illuminate and needs to adjust the shape and size of the emitted light spot, it should be noted that the fixed lens 2 and the movable lens 3 are the same as the first lens and the second lens in the reference document (in the reference document: the positional relationship of the wavy stripes on the opposite side of the first lens and the second lens is adjusted so that the wavy stripes are changed from the original corresponding complementary relationship to a vertically dislocated relationship, so that the light spot is changed from a circle to a square, and the size of the square light spot can be further adjusted by the displacement adjustment member), and then the user turns on the control The control switch 24 enables the battery 21 to power the LED lamp 22, so that the light emitted by the LED lamp 22 passes through the fixed lens 2 and the movable lens 3 and is emitted. When the movable lens 3 needs to be rotated, the rotating bin 4 is manually rotated clockwise, so that the rotating bin 4 drives the internal several first limiting grooves 6 to squeeze the elastic plate 5, so that the elastic plate 5 is compressed and deformed into the inside of the next first limiting groove 6, thereby continuously rotating to drive the fixed block 8 to push the second limiting groove 7 and the movable bin 14 to drive the top surface fixed ring 15 and the movable lens 3 to rotate, thereby changing the shape of the emitted light. After the rotation is completed, the elastic plate 5 enters the inside of the first limiting groove 6, so that the rotating bin 4 The rotating bin 4 will not rotate by itself, and when the rotating bin 4 is rotated, the limiting plate 13 is inserted into the third limiting groove 16 to vertically limit the rotating bin 4, so that the rotating bin 4 will not move up and down. Then, when it is necessary to adjust the distance between the fixed lens 2 and the movable lens 3, the movable bin 14 is pulled to move inside the rotating bin 4. At this time, the moving movable bin 14 drives several tooth grooves 11 to move, so that the teeth on one side of the tooth plate 23 slide with the tooth groove 11, and compresses the spring 10. Therefore, after adjusting to the appropriate height, the two tooth plates 23 engage with the tooth groove 11 under the push of the spring 10, so that the movable bin 14 will not move. It moves up and down, thereby keeping the movable lens 3 at this height, thereby completing the height adjustment of the movable lens 3, and then adjusting the size of the light spot. Moreover, when it is necessary to disassemble the rotating bin 4, the threaded column 18 is twisted to release the fixation of the limit plate 13, and the limit plate 13 is taken out from the inside of the second fixing hole 12, and then it can be pulled out from the inside of the shell 1, thereby achieving the comprehensive effect of rotating and adjusting the height of the movable lens 3, so that the shape (circular and square) and size of the emitted light spot can be adjusted, and after the adjustment is completed, the movable lens 3 can be kept at a fixed height without rotating or moving, thereby ensuring that the light spot effect is maintained, facilitating use, and being more practical.
