A locking support mechanism 10 is provided inside the telescopic cylinder. A tension handle 14 is provided in the middle of the fixed handle 13. The sliding guide frame 7 consists of a mounting frame 71, a mounting groove 72, and a fixed... The system consists of plate 73, limiting groove 74 and limiting member 75; power supply control mechanism 22 consists of sliding cavity 221, pull rod 222, conductive head 223 and contact protrusion 224; extrusion control mechanism 20 consists of splicing plate 201, connecting plate 202, extrusion plate 203 and deformable piece 204; locking and fixing mechanism 30 consists of moving guide rail 301, connecting groove 302, locking gear 303 and locking plate 304; and locking support mechanism 10 consists of locking frame 101, auxiliary groove 102 and reset piece 103.

[0033] The sliding guide rail 7 is composed of multiple mounting frames 71 and fixing plates 73. The upper end of the mounting frame 71 is provided with a mounting groove 72. The fixing plate 73 is located between two adjacent mounting frames 71 and is inserted into the mounting groove 72. The two ends of the fixing plate 73 are fixedly connected to the mounting frame 71 by bolts. The fixing plate 73 can connect the two mounting frames 71 together, so that the sliding block 18 can move inside the sliding guide rail 7, thereby changing the position of the auxiliary light 8. During shooting, the length of the sliding guide rail 7 can be adjusted by setting different numbers of mounting frames 71.

[0034] Limiting grooves 74 are provided on both inner walls of the mounting frame 71. The bottom of the limiting groove 74 is arc-shaped. The diameter of the opening of the limiting groove 74 is smaller than the maximum diameter of the limiting groove 74.

The lower side of the limiting member 75 is columnar. The two top ends of the lower side of the limiting member 75 are arc-shaped. When the limiting member 75 slides in the limiting groove 74, it can restrict the movement of the sliding block 18. The arc-shaped structure at the front end of the limiting member 75 can ensure that the sliding block 18 passes smoothly through the connection of the two mounting frames 71 when it moves, and prevent the auxiliary lamp 8 from getting stuck when it moves.

[0035] Multiple support rings 9 are fixedly connected to the middle of the suspension column 2. The distance between two adjacent support rings 9 is the same. Multiple positioning grooves 12 are provided on the upper end face of the support rings 9. The locking frame 101 has a Z-shaped structure. The right end of the locking frame 101 is slidably connected to the inner wall of the telescopic cylinder 3. The upper end of the locking frame 101 is provided with ball bearings. The side end of the telescopic cylinder 3 is threadedly connected with a compression bolt 11. The top end of the compression bolt 11 abuts against the side end of the locking frame 101. The auxiliary groove 102 is located in the middle part of the locking frame 101. The reset plate 103 is fixedly connected to the inner wall of the telescopic cylinder 3. The left side of the reset plate 103 has a vertical structure and abuts against the side end of the locking frame 101. The reset plate 103 passes through the auxiliary groove 102 at both ends. When the position of the main lamp 6 is adjusted, the support rings 9 at different positions are inserted into the telescopic cylinder 3. By rotating the compression bolt 11, the compression bolt 11 compresses the locking frame. When the locking frame 101 moves, it causes the reset plate 103 to deform and store force, thereby pushing the locking frame 101 to move. This causes the upper end of the locking frame 101 to abut against the support ring 9, thereby hanging the telescopic cylinder 3 on the support ring 9. The ball is engaged in the positioning groove 12 to limit and fix the position of the main lamp 6. When the angle of the main lamp 6 needs to be adjusted, simply lift the mounting block 4 to disengage the ball from the positioning groove 12.

[0036] The extrusion plate 203 is fixedly connected to the upper end of the splicing plate 201, and the connecting plate 202 is fixedly connected to the upper end of the splicing plate 201. The connecting plate 202 and the inner wall of the extrusion adjusting ball are slidably connected. The deformable piece 204 is an elastic iron sheet. The upper end of the deformable piece 204 is inserted into the inner wall of the angle adjusting ball 17. The deformable piece 204 has a V-shaped structure, and the lower end of the deformable piece 204 abuts against the splicing plate 201. There are multiple splicing plates 201, which have an arc-shaped structure. Multiple splicing plates 201 are combined to form a spherical structure. The angle adjusting ball 17 has multiple telescopic openings 21 in the middle. The extrusion plate 203 is slidably connected in the telescopic openings 21. The extrusion block 19... The lower end is provided with a fixing port 27, which is an arc-shaped structure. The inner wall of the fixing port 27 is provided with a friction layer. The upper end of the angle adjusting ball 17 is located inside the fixing port 27. The middle of the sliding block 18 is provided with a connecting groove 26, and the two ends of the connecting groove 26 pass through the sliding block 18. The angle adjusting ball 17 is located inside the connecting groove 26. The strong magnetic column 29 attracts the extrusion iron ball 24, causing the extrusion iron ball 24 to move upward and extrude the splicing plate 201 located directly below the strong magnetic column 29, causing the splicing plate 201 to move upward, thereby lifting the extrusion block 19, so that the angle adjusting ball 17 can rotate smoothly, thereby adjusting the angle and height of the auxiliary lamp 8.

[0037] Pull rod 222 and connecting rod 16 slide to connect rod 16. Both ends of pull rod 222 pass through connecting rod 16. Electromagnet 23 is fixedly connected to the top of pull rod 222. The lower end of pull rod 222 is fixedly connected to tension handle 14. A connecting spring 15 is provided between tension handle 14 and fixed handle. Sliding cavity 221 is located in the middle of connecting rod 16. Conductive head 223 is fixedly connected to the middle of pull rod 222. The side end of conductive head 223 has an inclined structure. Conductive head 223 and electromagnet 23 are electrically connected. Contact protrusion 224 is fixed. Connected to the inner wall of the sliding cavity 221, when the angle of the auxiliary lamp 8 needs to be adjusted, the pull handle 14 drives the pull rod 222 to slide in the connecting rod 16, thereby separating the conductive head 223 and the contact protrusion 224. The electromagnet 23 is de-energized, and the squeeze iron ball 24 can be attracted by the strong magnetic column 29, thereby squeezing the splicing plate 201. After the angle of the auxiliary lamp 8 is adjusted, the pull handle 14 is released, the electromagnet 23 is energized, and the squeeze iron ball 24 is attracted, thereby adsorbing the squeeze iron ball 24 onto the electromagnet 23.

[0038] The movable guide rail 301 is fixedly connected to the inner wall of the mounting frame 71. The upper end of the movable guide rail 301 is provided with a locking tooth. The connecting groove 302 is located on both sides of the lower end of the sliding block 18. The locking gear 303 is rotatably connected in the connecting groove 302. The lower end of the locking gear 303 is meshed with the movable guide rail 301. The locking plate 304 passes through the sliding block 18 at both ends. The upper end of the locking plate 304 is fixedly connected to the pressing block 19. The lower end of the locking plate 304 is located at the locking gear 303. The auxiliary lamp 8 is stopped at different positions through the meshing connection between the locking gear 303 and the locking tooth. When the angle adjustment ball 17 adjusts the angle, the locking plate 304 moves upward with the pressing block 19, thereby unlocking the locking gear 303 and allowing the sliding block 18 to move. When the angle adjustment ball 17 has finished adjusting the angle, the locking plate 304 moves downward with the pressing block 19 to lock and fix the locking gear 303. At this time, the sliding block 18 cannot move.

[0039] When the position and angle of the auxiliary lamp 8 need to be adjusted, the pull rod 222 is slid within the connecting rod 16 by pulling the handle 14. At this time, the contact protrusion 224 and the conductive head 223 separate, the magnet 23 is de-energized, and the squeezing iron ball 24 is attracted by the strong magnetic column 29, thereby squeezing the splicing plate 201 located directly below the strong magnetic column 29, extending the squeezing plate 203 out of the telescopic opening 21, and lifting the squeezing block 19, so that the angle adjustment ball 17 can rotate smoothly, thereby adjusting the angle of the auxiliary lamp 8. At this time, the squeezing block 19 and the locking plate 304 move upward together, unlocking the locking gear 303, allowing the sliding block 18 to move and adjust the position of the auxiliary lamp 8. When the height and angle of the main lamp 6 need to be adjusted, it is limited and fixed by the locking bracket 101.
