[0034] The base 100 is provided with a rotating cavity 110 and a movable cavity 120;

[0035] The ball head 200 is disposed in the rotating cavity 110 and has a tapered groove 210 thereon;

[0036] The movable seat 300 is disposed within the movable cavity 120 and has a tapered protrusion 310 thereon, and has a lockable position and an unlockable position that can be switched between each other;

[0037] The retaining component 400 is disposed within the movable cavity 120 and connected to the movable seat 300, for keeping the movable seat 300 in the locked or unlocked position;

[0038] The pressure plate 500 is mounted on the base 100 and connected to the movable seat 300, and is used to switch the movable seat 300 between the locked position and the unlocked position.

[0039] The tapered protrusion 310 can be inserted into the tapered groove 210 when the movable seat 300 is in the locked position to restrict the rotation of the ball head 200 in the rotating cavity 110, or the tapered protrusion 310 can disengage from the tapered groove 210 when the movable seat 300 is in the unlocked position so that the ball head 200 can rotate in the rotating cavity 110.

[0040] In this utility model, when it is necessary to lock the ball head 200, the movable seat 300 is operated to enter the locking position by the pressure plate 500. The movable seat 300 is linked to the retaining component 400, which keeps the movable seat 300 in the locking position. When the movable seat 300 is in the locking position, the conical protrusion 310 on it will be inserted into the conical groove 210 of the ball head 200. The ball head 200 is restricted from rotating in the rotating cavity 110 by the abutment between the conical protrusion 310 and the conical groove 210. When the ball head 200 needs to be unlocked, the movable seat 300 is operated to enter the unlocked position by the pressure plate 500. The movable seat 300 is linked to the retaining component 400, which keeps the movable seat 300 in the unlocked position. When the movable seat 300 is in the unlocked position, its conical protrusion 310 will disengage from the conical groove 210 of the ball head 200, and the ball head 200 can rotate within the rotating cavity 110. When the camera is mounted on the ball head 200, the shooting angle of the camera can be changed.

[0041] Reference Figures 1 to 3 In some embodiments, the retaining component 400 includes a fixed base 410, a movable block 420, and a reset member 430; the fixed base 410 is installed in the movable cavity 120, the upper end of the fixed base 410 is provided with a through groove 440 through which the conical protrusion 310 passes, and the lower end is provided with a plurality of alternately arranged first locking positions 450 and second locking positions 460; the movable base 300 is disposed in the fixed base 410; the movable block 420 abuts against the lower end of the movable base 300, and the movable block 420 is circumferentially provided with a plurality of abutment blocks 470. 70 can be switched between the first locking position 450 and the second locking position 460; the two ends of the reset member 430 abut against the movable block 420 and the base 100 respectively; the holding block 470 can abut against the first locking position 450 when the pressure plate 500 operates the movable seat 300 into the locking position, so that the movable seat 300 is inserted into the conical groove 210 through the through groove 440, or the holding block 470 can abut against the second locking position 460 when the pressure plate 500 operates the movable seat 300 into the unlocking position, so that the movable seat 300 is disengaged from the conical groove 210.

[0042] Specifically, when it is necessary to lock the ball head 200, the pressure plate 500 operates the movable seat 300 to push the movable block 420 downward. The abutment block 470 on the movable block 420 switches from the second locking position 460 to the first locking position 450. It should be noted that the depth of the first locking position 450 is greater than the depth of the second locking position 460, so that the abutment block 470 can slide to the highest point of the first locking position 450 under the action of the reset member 430. This causes the movable block 420 to push the movable seat 300 toward the ball head 200 until the tapered protrusion 310. Inserted into the conical groove 210 of the ball head 200, the ball head 200 is restricted from rotating within the rotating cavity 110. When it is necessary to unlock the ball head 200, the pressure plate 500 operates the movable seat 300 to push the movable block 420 downward. The abutment block 470 on the movable block 420 switches from the first locking position 450 to the second locking position 460, so that the movable block 420 is kept away from the ball head 200, that is, the conical protrusion 310 disengages from the conical groove 210 and remains in the disengaged state. At this time, the ball head 200 can rotate within the rotating cavity 110.

[0043] Reference Figures 1 to 3 In some embodiments, the lower end of the movable seat 300 is provided with a plurality of conical teeth 320, and the upper end of the abutment block 470 is provided with an inclined surface 471 adapted to the conical teeth 320. The inclined surface 471 can abut with different conical teeth 320 so that the abutment block 470 can switch between the first locking position 450 and the second locking position 460. The cooperation between the inclined surface 471 and the conical teeth 320 enables the abutment block 470 to transition from the first locking position 450 to the second locking position 460, or from the second locking position 460 to the first locking position 450, that is, the movable block 420 rotates within the fixed seat 410.

[0044] Reference Figures 1 to 3 In some embodiments, the movable seat 300 is provided with a plurality of limiting blocks 330, and the fixed seat 410 is provided with a plurality of limiting grooves 411, with the limiting blocks 330 extending into the limiting grooves 411; preferably, the limiting grooves 411 are formed by first locking positions 450; the cooperation between the limiting blocks 330 and the limiting grooves 411 restricts the movable seat 300 from rotating within the fixed seat 410, while not hindering the movable seat 300 from sliding vertically within the fixed seat 410.

[0045] Reference Figures 1 to 3In some embodiments, one end of the pressure plate 500 is rotatably connected to one side of the base 100, the middle section is provided with a waist-shaped groove 510, and the other end is located on the other side of the base 100. The fixed seat 410 is provided with a sliding groove 412 arranged along the height direction, and the movable seat 300 is provided with a through groove 340. It also includes a pressure rod 600 passing through the waist-shaped groove 510, the sliding groove 412 and the through groove 340. When the pressure plate 500 is operated, it will rotate around the rotation axis of the pressure plate 500 and the base 100. The waist-shaped groove 510 provides space for the downward movement of the pressure rod 600. The pressure rod 600 drives the movable seat 300 to push the movable block 420, thereby realizing the retention component 400 maintaining the state of the movable seat 300.

[0046] Reference Figures 1 to 3 In some embodiments, the base 100 is circumferentially provided with a first leg 710, a second leg 720, and a third leg 730. The first leg 710, the second leg 720, and the third leg 730 are rotatably connected to the base 100 and are used to rotate inward to fold or rotate outward to unfold. When needed, the first leg 710, the second leg 720, and the third leg 730 are rotated outward to unfold, providing stable support for the support frame and photographic equipment. When the support frame is not needed, the first leg 710, the second leg 720, and the third leg 730 are rotated inward to fold, making them easy to carry and improving ease of use.

[0047] Reference Figures 1 to 3 In some embodiments, the first leg 710, the second leg 720, and the third leg 730 are all connected to the base 100 via a locking assembly 800 to keep the first leg 710, the second leg 720, and the third leg 730 in an extended state.

[0048] Reference Figures 1 to 3 In some embodiments, a ground nail 900 is provided at the lower end of the base 100; the stability of the support frame can be further improved by the cooperation of the ground nail 900, the first leg 710, the second leg 720 and the third leg 730.

[0049] A support frame including the aforementioned quick-locking structure.

[0050] The advantage of this invention is that the movement of the ball head in the rotating cavity can be controlled by pressing the pressure plate, which improves the convenience of use and meets the needs of use.

[0051] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
