It can be understood that when the lens holder 52 needs to be adjusted to move along the length direction of the first side wall 522, the third bolt 543 can be firstly unscrewed from the second threaded hole 5232, at this time, the third bolt 543 is unscrewed from the second threaded hole 5232 by a certain distance, the third bolt 543 can move in the fourth threaded hole 5321, and then the fourth bolt 544 can only rotate in the second threaded hole 5231 and cannot move, so that the moving distance of the lens holder 52 can be adjusted by adjusting the locking depth of the fourth bolt 544 in the fourth threaded hole 5322, at this time, the first waist hole 5313 slides along the fifth bolt 60; if the moving distance of the lens holder 52 is too long, the fourth bolt 544 can be loosened from the fourth threaded hole 5322 to drive the lens holder 52 to move in the opposite direction, so that the lens holder 52 returns; in the process of adjusting the lens holder 52 to move along the length direction of the first side wall 522, the length of the first waist hole 5313 limits the moving distance of the lens holder 52, and the fifth bolts 60 located at the two sides of the lens holder 52 can prevent the lens holder 52 from shaking when moving.
When the lens fixing frame 52 is adjusted to move along the length direction of the second side wall 523, the first bolt 541 is firstly loosened from the first threaded hole 5222, at this time, the first bolt 541 is loosened a distance from the first threaded hole 5222, the first bolt 541 can move in the third through hole 5311, then, because the second bolt 542 can only rotate and can not move in the first through hole 5221, the moving distance of the lens fixing frame 52 can be adjusted by adjusting the locking depth of the second bolt 542 in the third threaded hole 5312, and at this time, the second waist hole 5323 slides along the sixth bolt 70; if the moving distance of the lens fixing frame 52 is adjusted to be too long, the second bolt 542 can be loosened from the third threaded hole 5312 to drive the lens fixing frame 52 to move in the opposite direction, so that the lens fixing frame 52 returns; in the process of adjusting the lens holder 52 to move along the length direction of the second side wall 523, the length of the second waist hole 5323 limits the moving distance of the lens holder 52, and the sixth bolts 70 located at the two sides of the lens holder 52 can prevent the lens holder 52 from shaking when moving.
