[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 2 The utility model provides an embodiment: a rectangular fill light for making and shooting promotional films, including a support frame 1, the top of the support frame 1 is detachably connected to a base 2, the inner wall of the base 2 is rotatably connected to a rotating shaft 5, the outer wall of the rotating shaft 5 is fixedly connected to a movable block 3, the top of the movable block 3 is fixedly connected to a fill light body 4, the rotation of the rotating shaft 5 will cause the movable block 3 to change the angle of the fill light body 4, and adjust the fill light effect, the inner wall of the rotating shaft 5 is elastically connected to a buckle assembly through a reset spring a6, the buckle assembly includes a clamping block 7, one end of the reset spring a6 is in contact with the back of the clamping block 7, and the reset spring a6 The other end is fixedly connected to the inner wall of the rotating shaft 5. The block 7 can squeeze the reset spring a6 to move outward. At the same time, the elastic force generated by the deformation of the reset spring a6 gives the block 7 a thrust in the opposite direction, prompting it to reset. The outer wall of the base 2 is provided with a plurality of groups of slots 9. The outer wall of the block 7 is engaged with the inner wall of the slot 9. The block 7 is inserted into the slot 9 to fix the angle of the fill light body 4. The inner wall of the rotating shaft 5 is slidably connected with a knob 8. The inner end of the knob 8 is fixedly connected to the outer wall of the block 7. Turning the knob 8 can make the block 7 drive the rotating shaft 5 to rotate, thereby adjusting the angle of the fill light body 4.

[0030] Reference Figure 1 and Figure 3The bottom of the base 2 is provided with a circular groove 14, and the top of the support frame 1 is plugged into the circular groove 14. The support frame 1 can be inserted into the circular groove 14 to connect the support frame 1 and the base 2 together. The inner wall of the base 2 is elastically connected to the limit block 11 through the return spring b10. One end of the return spring b10 is fixedly connected to the inner wall of the base 2, and the other end of the return spring b10 is fixedly connected to the back of the limit block 11. The limit block 11 can squeeze the return spring b10 to move outward. At the same time, the return spring b10 is in the shape of The elastic force generated by the change gives the limit block 11 a thrust in the opposite direction, prompting it to reset. A limit groove 12 is provided at the top of the support frame 1, and the outer wall of the limit block 11 is engaged with the inner wall of the limit groove 12. The limit block 11 is inserted into the limit groove 12 to connect the base 2 and the support frame 1 together.
