[0012] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0013] Such as Figure 1-2As shown, the utility model provides a single-leg quick-release joint, including an inner sleeve 7, the upper end of the inner sleeve 7 is connected with a steel ball sleeve 6, the interior of the steel ball sleeve 6 is provided with an axially liftable brake seat 4, the outer side of the steel ball sleeve 6 is sleeved with an axially movable movable seat 11, the upper end inner side of the movable seat 11 is axially connected with a locking sleeve 12, the upper end of the steel ball sleeve 6 is provided with a main body base 3, the upper end of the brake seat 4 is abutted against the bottom of the main body base 3, the lower outer side of the main body base 3 is provided with a clamping step 31, the upper end of the main body base 3 is connected with a mounting platform 1, the lower side wall of the steel ball sleeve 6 is passed through with a lower locking steel ball 8, the steel An upper locking steel ball 9 is provided on the upper side wall of the ball sleeve 6, and the upper locking steel ball 9 is located between the clamping step 31 and the locking sleeve 12. A safety spring 5 is installed between the lower end of the brake seat 4 and the inner sleeve 7. The inner side sleeve of the movable seat 11 is provided with a locking spring 10. The upper end of the locking spring 10 is against the locking sleeve 12, and the lower end is against the outer side wall of the steel ball sleeve 6. By setting the brake seat 4, the main base 3 can be automatically pushed out when the movable seat 11 moves downward, and disassembly is very convenient. Sometimes, installation can be achieved by simply inserting the main base 3 from the top into the upper end of the steel ball sleeve 6 and clamping it with the upper locking steel ball 9, so one-click disassembly and quick installation can be achieved.

[0014] Specifically, when the outer side of the upper locking steel ball 9 is supported by the locking sleeve 12 and the inner side is located on the upper side of the clamping step 31, the main body base 3 can be clamped and positioned to complete the installation. The upper outer side and the lower outer side of the clamping step 31 are both provided with inclined surfaces, so when the main body base 3 is inserted into the steel ball sleeve 6, the upper locking steel ball 9 can be pushed outward to achieve automatic clamping installation.

[0015] A limiting step is also provided at the bottom of the brake seat 4, and a slope is also provided at the top of the limiting step. The lower locking steel ball 8 contacts the slope. When the movable seat 11 is manually moved down, the lower locking steel ball 8 will be pushed outward by the brake seat 4, allowing the brake seat 4 to push up, thereby realizing the effect of the brake seat 4 pushing out the main base 3.

[0016] In this embodiment, if Figure 1 As shown, a conical surface is provided on the inner side wall of the locking sleeve 12, and a steel ball receiving groove 13 is provided on the upper side of the conical surface. When the movable seat 11 moves downward, the upper locking steel ball 9 is embedded in the steel ball receiving groove 13, and the conical surface can push the movable seat 11 downward when the upper locking steel ball 9 is pushed outward by the clamping step 31, so that the main base 3 is more convenient to install. When the movable seat 11 actively moves downward, the upper locking steel ball 9 can enter the steel ball receiving groove 13, and the main base 3 can be pushed out by the brake seat 4.

[0017] For convenient use, a double-headed connecting screw 2 is embedded and installed in the middle of the installation platform 1, which can be used to connect a camera.

[0018] Meanwhile, a limiting step 14 is arranged on the outer side of the steel ball bushing 6. The lower end of the locking spring 10 abuts against the upper side of the limiting step 14. A boss that abuts against the lower end of the limiting step 14 is arranged on the inner side of the lower part of the movable seat 11, which can limit the automatic rebound and upward movement of the movable seat 11.
