An installation step is arranged on the lower side of the outer wall of the locking rod 10. The lower end of the locking rod 10 is provided as an inclined surface. The reset spring 12 is connected between the installation step and the inner supporting ring 11. The locking block 9 pushes the adjusting ball head 4 upward, and the adjusting ball head 4 is pressed between the locking groove and the positioning ring 6 to form a lock, so that the rotation of the adjusting ball head 4 in the locked state can be avoided.

[0029] A sliding hole is formed in the middle of the lamp holder body 1, and a guide groove extending in the same direction as the sliding hole is arranged in the middle of the lamp holder body 1. The sliding rod 7 horizontally slides through the sliding hole. A guide block is fixed to the side wall of the sliding rod 7. The guide block is slidably installed in the guide groove. An inclined sliding groove 13 is formed in the middle of the sliding rod 7. The lower end of the locking rod 10 abuts against the side wall of the inclined sliding groove 13. The inclination of the inclined sliding groove 13 is equal to the inclination of the inclined surface of the lower end of the locking rod 10.

[0030] The locking ring 8 is rotationally connected to the outer side of the lamp holder body 1. An abutting arc piece 14 is arranged on the inner wall of the locking ring 8. The abutting arc piece 14 is provided as a convex piece with gradually increasing thickness. The starting point of the abutting arc piece 14 is flush with the inner wall of the locking ring 8. An inner recessed ring groove is formed in the middle of the ring groove two 3. The end of the sliding rod 7 protrudes into the inner recessed ring groove. The abutting arc piece 14 is slidably placed in the inner recessed ring groove. The abutting arc piece 14 abuts against the outer end of the sliding rod 7. The thickness of the abutting arc piece 14 on the inner wall of the locking ring 8 is opposite to the position of the end of the sliding rod 7. The sliding rod 7 slides in and out in the sliding hole. In this way, the position of the inclined sliding groove 13 on the sliding rod 7 changes, the locking or unlocking of the adjusting ball head 4 is pushed, and the reset spring 12 pulls the locking rod assembly to slide downward and always abut against the inclined sliding groove 13 to unlock the adjusting ball head 4.

[0031] A locking ring 15 is slidably mounted on the outer wall of the lamp holder body 1. A dividing ring 16 is integrally formed in the middle of the locking ring 15, which divides the upper and lower parts of the locking ring 15 into a closed ring and an engaging ring. The inner diameter of the closed ring is equal to the outer diameter of the annular groove 2, and the closed ring is slidably fitted on the annular groove 2. The inner diameter of the dividing ring 16 is equal to the outer diameter of the annular groove 3, and the dividing ring 16 is slidably fitted on the outer wall of the annular groove 3. A base locking ring 17 is integrally formed and fixed at the lower end of the lamp holder body 1. The outer wall of the base locking ring is flush with the outer wall of the annular groove 2. The inner diameter of the engaging ring is equal to the outer diameter of the annular groove 2, and the engaging ring is slidably fitted on the outside of the annular groove 2 and the base locking ring 17.

[0032] The outer wall of the locking ring 8 has several longitudinally extending engagement grooves 18. The inner wall of the locking button ring 15 is fixed with a locking strip 20 that convexly and concavely engages with the engagement grooves 18. The locking strip 20 and the engagement grooves 18 are slidably connected in the longitudinal direction, and the locking strip 20 and the engagement grooves 18 are mutually locked in the circumferential direction. That is, rotating the locking button ring 15 can synchronously drive the locking ring 8 to rotate together. A locking spring 21 is connected between the lamp holder body 1 and the locking button ring 15, and the closing ring is covered by the locking spring 21. On the outside of 1, the locking spring 21 is prevented from being exposed to the outside and rusting. The upper end of the locking spring 21 is fixedly connected to the side wall of the annular groove 3, and the lower end of the locking spring 21 is rotatably connected to the partition ring 16. The base locking ring 17 has a locking groove 19. The locking bar 20 slides through the locking groove 19. When the locking button ring 15 slides down into the locking groove 19, it will lock the button ring 15 in the circumferential direction, which can prevent the adjusting ball head 4 from being unlocked due to the loosening of the locking button ring 15.

[0033] Working principle:

[0034] In the natural state of this invention, the locking spring 21 abuts against the locking ring 15 and is held at its lowest position. That is, the locking strip 20 on the locking ring 15 passes through both the engagement groove 18 and the locking groove 19 on the base locking ring 17. The locking groove 19 locks the locking ring 15. In this state, the locking ring 15 cannot rotate.

[0035] When adjustment is required, manually pull the locking ring 15 upwards until its upper end abuts against the upper side wall of the ring groove 2. At this point, the locking bar 20 completely disengages from the locking slide groove 19, thus unlocking the locking ring 15. The locking ring 15 can then be rotated, causing the locking ring 8 to rotate along with it via the locking bar 20. During the rotation of the locking ring 8, the contact arc plate 14 rotates relative to the end of the sliding rod 7. As the thickness of the contact arc plate 14 relative to the sliding rod 7 gradually decreases, the sliding rod 7 is supported by the return spring 12 and locked. The locking rod 10 is pressed against the inclined slide groove 13 by the inclined surface. The sliding rod 7 slides outward by sliding on the inclined surface, which can make the locking rod assembly move down and lock the adjusting ball head 4. The angle of the adjusting ball head 4 can be adjusted. After adjustment, the locking button ring 15 is rotated in the opposite direction to make the sliding rod 7 slide inward. The locking rod assembly is pressed against the adjusting ball head 4 by sliding on the inclined surface, locking the adjusting ball head 4. After locking, the locking button ring 15 is lowered to make the locking strip 20 extend into the locking slide groove 19 to form a lock and prevent loosening caused by the inclined surface pressing.

[0036] In this utility model, the locking ring 15 and locking ring 8 replace the protruding fastening bolt, making the adjustable fill light holder into a cylindrical shape, which facilitates the storage of the locking ring 15.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
