[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Combined with attachment Figure 1 To the attached Figure 4 , a torsional quick-release structure of a monopod, comprising a foot main body insert 2 fixedly arranged at the bottom of the monopod upright, and also comprising an upper quick-release base 10 fixedly arranged at the upper end of the monopod footrest, a quick-release shaft 3 is fixedly provided at the bottom of the foot main body insert 2, a quick-release body 6 is fixedly provided at the upper end of the upper quick-release base 10, the quick-release body 6 is externally rotatably provided with a locking knob 8, the inner wall of the locking knob 8 is fixedly provided with an arc-shaped plug-in plate 12 for locking the quick-release shaft 3, the locking knob 8 is externally fixed with a gear disc sleeve 1, the bottom surface of the quick-release body 6 is movably plugged with a quick-release screw 4, a limit pin 5 is fixed on the quick-release screw 4, the limit pin 5 passes through the side of the quick-release body 6 and is clearance-matched with the quick-release body 6, the bottom of the quick-release screw 4 is sleeved with an adjusting spring 7, and a torsion spring 9 is connected between the locking knob 8 and the upper quick-release base 10.

[0024] The quick-release shaft 3 is inserted into the inner cavity of the quick-release body 6, and a notch 13 is provided on the side of the quick-release shaft 3 for the insertion and locking of the curved insert plate 12. A through hole is provided on the side wall of the quick-release body 6 for the curved insert plate 12 to extend into. The bottom portion of the curved insert plate 12, located outside the quick-release body 6, is provided with a stop boss 14 that mates with the stop pin 5.

[0025] Specific implementation method of the present utility model: When the monopod needs to be installed, first, a toothed disc sleeve 1 is fixed to the outside of the locking knob 8 to facilitate the rotation operation. The toothed disc sleeve 1 and the locking knob 8 are rotated to drive the arc-shaped plug plate 12 to retract to the outside of the quick-release body 6. At this time, the torsion spring 9 is compressed and deformed. As the arc-shaped plug plate 12 retracts, the limiting boss 14 releases the pressure on the limiting latch 5 and the quick-release screw 4. The quick-release screw 4 is lifted up under the action of the adjusting spring 7 until the limiting latch 5 is engaged with one side of the limiting boss 14. At this time, the limiting latch 5 plays a role in limiting the arc-shaped plug plate 12 from popping out. Then the quick-release shaft 3 is aligned with the quick-release body 6, and the quick-release shaft 3 is inserted into the inner cavity of the quick-release body 6. At this time, the quick-release screw 4, which is movably connected to the bottom surface of the quick-release body 6, is in an upward position under the action of the adjustment spring 7. When the quick-release shaft 3 is inserted, the quick-release screw 4 is pressed downward, and the limit pin 5 fixed to the quick-release screw 4 moves downward with the quick-release screw 4. When the limit pin 5 disengages the limit boss 14, the arc-shaped insert plate 12 quickly rebounds under the action of the torsion spring 9, extends through the through hole in the side wall of the quick-release body 6, and inserts into the notch 13 of the quick-release shaft 3, thereby locking the quick-release shaft 3. When the monopod needs to be disassembled, the locking knob 8 is rotated in the opposite direction to make the arc-shaped insert plate 12 withdraw from the notch 13 of the quick-release shaft 3, and the quick-release shaft 3 can be easily removed. The quick-release screw 4 is then lifted up again under the action of the adjustment spring 7, and the disassembly is completed.

[0026] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
