[0039] The elastic member 25 is a torsion spring, which is sleeved outside the fixing pin 117. The first end of the torsion spring abuts against the unlocking button 2, and the second end of the torsion spring abuts against the seat body 11. The hinged portion 22 of the unlocking button 2 is hinged to the fixing pin 117 and rotates around the fixing pin 117. The hinged portion 22 and the winding portion of the torsion spring are coaxially arranged. The quick-release seat 1 includes a bottom cover 26, which is fixedly connected to the lower end surface, and the bottom cover 26 covers part of the rotating slide groove 114. The bottom cover 26 is provided with a supporting protrusion 261 on the rotating slide groove 114, and the unlocking button 2 is provided with an avoidance groove 248. The first end of the torsion spring abuts against the avoidance groove 248, and the supporting protrusion 261 is located in the avoidance groove 248.

[0040] Reference Figure 5 , and combined with Figure 1 In the locked state, the fixed card slot 112 and the movable card slot 21 are respectively engaged with the card block 31 on the corresponding side, the unlocking toggle end 242 protrudes from the unlocking slide slot 23, the locking toggle end 241 moves into the unlocking slide slot 23, and the unlocking toggle end 242 cooperates with the locking block 118 to limit the unlocking button 2 from rotating downward, thereby realizing the locking of the quick release plate 3 and the unlocking button 2.

[0041] Reference Figure 6 , and combined with Figure 1 In the unlocked state, the locking column 24 is moved horizontally by toggling the unlocking toggle end 242, and the unlocking toggle end 242 moves into the unlocking slot 23, and the locking toggle end 241 protrudes out of the unlocking slot 23, and then the unlocking toggle end 242 is separated from the locking block 118, so that the unlocking button 2 can be rotated downward.

[0042] As the unlocking button 2 is pressed, the movable card slot 21 is driven to separate from the card block 31 on the corresponding side, so that the quick-release plate 3 can be easily taken out.

[0043] The pan-tilt mechanism includes a support structure and a quick clamp seat 1 as in the above-mentioned solution, the support structure is connected to the fixing part 113, and the support structure can be a support frame, a tripod, a universal adjustment table, a fixed rocker arm or a rocker arm of an electric pan-tilt, etc.

[0044] As can be seen from the above, through the elastic rotation of the unlocking button, the movable card slot can be quickly and detachably engaged with the card block, which is convenient for the quick installation and removal of the quick release plate. In addition, the locking column is arranged in the pull part, and the locking column and the locking block are detachably limited to cooperate, so as to achieve the locking of the pull part, and the unlocking can be achieved by simply moving the locking column horizontally, which not only effectively locks the position of the pull part to avoid accidental touching, but also facilitates the unlocking operation of the pull part.
