Further, the first direction is perpendicular to the second direction. The first direction is perpendicular to the second direction, so that the light source mechanism 110 can move to any position in a plane formed by the first direction and the second direction.

In some embodiments, the light source mechanism 110 is detachably disposed on the first sliding mechanism 120, and may be fixed by a screw or a clamping structure, which is not limited in this application.

As shown in fig. 2b, the other end of the first sliding mechanism 120 has a protruding portion, and the other end of the second sliding mechanism 130 has an embedded portion; the protruding portion of the first slide mechanism 120 is disposed in the embedded portion of the second slide mechanism 130.

When the second sliding mechanism 130 moves in the second direction, the first sliding mechanism 120 is driven to move in the second direction along with the second sliding mechanism 130.

The length of the protruding portion of the first sliding mechanism 120 is smaller than the length of the embedded portion of the second sliding mechanism 130, and the direction of the length of the embedded portion of the second sliding mechanism 130 is the first direction, so that the first sliding mechanism 120 can move back and forth along the first direction in the length direction of the embedded portion of the second sliding mechanism 130.

Although the second adjustment assembly 131 acts only on the second slide mechanism 130, the other end of the first slide mechanism 120 is disposed within the second slide mechanism 130, and thus, as the second slide mechanism 130 moves back and forth in the second direction, the first slide mechanism 120 also moves with the second slide mechanism 130.

When the first adjusting component 121 and the second adjusting component 131 are adjusted, the position adjustment of the second sliding mechanism 130 and the first sliding mechanism 120 in the second direction in the light source adjusting device 100, and the position adjustment of the first sliding mechanism 120 in the first direction, that is, the position adjustment of the light source mechanism 110 in the first direction and the second direction, can be realized.

The first through hole 141 has a raised first ring 141a therein, and the cross-sectional area of the first ring 141a is smaller than that of the first through hole 141. The first ring 141a restricts the screw head of the first adjusting screw 121b from passing through the first through hole 141, thereby improving the stability of the moving position of the first sliding mechanism 120.

In some embodiments, the first ring 141a may be located in the middle of the first through hole 141, or in the middle of the first through hole 141, near the outer shell of the base, or in the middle of the first through hole 141, near the inner shell of the base; reserving the positions of the first through holes 141 on the two sides of the first ring 141 a; it is realized that the side of the first ring 141a adjacent to the base inner case may restrict the other end of the first locking spring 121a, and the side of the first ring 141a adjacent to the base outer case may restrict the screw head of the first adjusting screw 121b.

The first adjusting screw 121b has a thread on a side away from the screw head, and is movably connected to the first sliding mechanism 120 through a first thread portion 122a of the first adjusting through hole 122. That is, the first screw portion 122a can extend or contract the first lock spring 121a, and thus the first slide mechanism 120 can reciprocate in the first direction.

It should be understood that since the cross-sectional area of the second fixing portion is greater than that of the second screw part, the communication position of the second fixing portion and the second screw part has a second step for restraining one end of the second locking spring 131a.

The second locking spring 131a is sleeved on one side of the second adjusting screw 131b close to the screw head, and the second locking spring 131a is located between one end of the second fixing portion and the screw head of the second adjusting screw 131b, wherein one end of the second fixing portion is connected with the second thread portion.

And the second through hole is internally provided with a raised second circular ring, and the cross section area of the second circular ring is smaller than that of the second through hole. The second ring limits the screw head of the second adjusting screw 131b not to pass through the second through hole, thereby improving the stability of the moving position of the second sliding mechanism 130.

In some embodiments, the second ring may be located in the middle of the second through hole, or in the middle of the second through hole near the outer casing of the base, or in the middle of the second through hole near the inner casing of the base; reserving a second through hole on two sides of the second ring; the other end of the second locking spring can be limited by the side of the second ring close to the base inner shell, and the screw head of the second adjusting screw 131b can be limited by the side of the second ring close to the base outer shell.

The second adjusting screw 131b has a thread on a side away from the screw head, and is movably connected to the second sliding mechanism 130 through a second thread portion of the second adjusting through hole. That is, the second locking spring 131a can be extended or shortened by the second screw portion, and the second sliding mechanism 130 can be reciprocated in the second direction.
