So that the telescopic rod 200 fully utilizes the space of the top slot 1121, and the telescopic rod 200 is prevented from occupying the space outside the top slot 1121, so that the occupied space of the whole lighting fixture 10 is reduced. The maximum length of the telescopic rod 200 after extension can reach 1.8m.

Referring to fig. 4, 5, 6 and 7, in some embodiments, the telescopic rod 200 is rotatably connected to the base 110 through a first rotation mechanism 300, and a central axis of the first rotation mechanism 300 may be denoted as a first axis 310, so that the telescopic rod 200 can rotate around the first axis 310 relative to the base 110, and the first axis 310 may be perpendicular to a length direction of the base 110. The first rotating mechanism 300 includes a first rotating member 320 and a first fixing member 330, the number of the first rotating member 320 is one, the number of the first fixing members 330 is two, and the first rotating member 320 and the first fixing member 330 are coaxially disposed. The first fixing member 330 may include a first coarse fixing cylinder 331 and a first fine fixing cylinder 332, where the first coarse fixing cylinder 331 is sleeved outside the first fine fixing cylinder 332, so that an outer diameter of the first coarse fixing cylinder 331 is greater than an outer diameter of the first fine fixing cylinder 332, a first fixing tooth 3311 is disposed at an end portion of the first coarse fixing cylinder 331, and a plurality of first fixing teeth 3311 are disposed along a circumferential direction of the first coarse fixing cylinder 331 at intervals. The first rotating member 320 may be a cylindrical structure, and both ends of the first rotating member 320 are provided with first rotating teeth 321, and the first rotating teeth 321 are disposed at intervals along the circumferential direction of the first rotating member 320.

Therefore, when the first rotating member 320 rotates to stay at a certain position, since the two first fixing members 330 cannot rotate relative to the base 110 at the same time, the first rotating member 320 is effectively prevented from deflecting slightly due to the existence of the movable space at the position, and the position accuracy of the first rotating member 320 after rotation is improved.

The second fixing member 530 may include a second thick fixing cylinder 531 and a second thin fixing cylinder 532, both of which are cylindrical, the second thick fixing cylinder 531 is sleeved outside the second thin fixing cylinder 532, so that an outer diameter of the second thick fixing cylinder 531 is greater than an outer diameter of the second thin fixing cylinder 532, second fixing teeth 5311 are provided at an end portion of the second thick fixing cylinder 531, a number of the second fixing teeth 5311 is plural, and the second fixing teeth 5311 are disposed along a circumferential direction of the second thick fixing cylinder 531 at intervals.

When the adaptor 400 rotates relative to the telescopic rod 200, the second rotating member 520 rotates relative to the second fixing member 530, and the rotated second rotating member 520 stays at a desired position relative to the second fixing member 530 through the meshing force between the second rotating teeth 521 and the second fixing teeth 5311, so that the adaptor 400 rotates at a certain angle relative to the telescopic rod 200 and stays at a desired position.

Through the cooperation of the second clamping groove 5321 and the adaptor 400, a good circumferential limiting effect can be achieved on the second thin fixing cylinder 532, and the second thin fixing cylinder 532 and the whole second fixing piece 530 are prevented from rotating relative to the base 110.

After the two second fixing members 530 are assembled, the second clamping grooves 5321 on the two second thin fixing cylinders 532 are not on the same straight line, so that the two second clamping grooves 5321 are staggered along the axial direction of the second thin fixing cylinders 532, and thus the two second fixing members 530 cannot rotate within a small range relative to the adapter 400 at the same time. Therefore, when the second rotating member 520 rotates to stay at a certain position, since the two second fixing members 530 cannot rotate relative to the adaptor 400 at the same time, the second rotating member 520 is effectively prevented from deflecting slightly due to the existence of the movable space at the position, and the position accuracy of the second rotating member 520 after rotation is improved.

When the light emitting body 600 rotates around the third axis 611 with respect to the adapter 400, the light emitting body 600 may rotate at a certain angle with respect to the adapter 400 to stay at a desired position. So that the light emitting surface 621 of the light 600 can be directed to a desired position.

Then, the adaptor 400 rotates relative to the telescopic rod 200, and the light emitting body 600 rotates relative to the adaptor 400, so that the light emitting surface 621 of the light emitting body 600 faces the top slot 1121, and of course, the light emitting surface 621 may also face away from the top slot 1121, and the light emitting body 600 is stacked on the top surface 112 of the base 110 and covers the top slot 1121. The whole lighting lamp 10 is folded to form a shape similar to a cuboid, so that the occupied space of the lighting lamp 10 can be reduced, and the convenience in carrying, storing and using the lighting lamp 10 is improved.

Then, the telescopic rod 200 is rotated to the outside of the top slot 1121 with respect to the base 110, and the length of the telescopic rod 200 is adjusted, so that the illuminant 600 emits light at a reasonable height, and then the illuminant 600, the adapter 400 and the telescopic rod 200 are rotated, so that the light emitting surface 621 of the illuminant 600 faces in a desired direction.
