For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the invention.

[0025] The preferred embodiments provided by the present invention are as follows: Figures 1-4 As shown, a quick-release handle for fixing a ball cup on a tripod includes a handle body 1, a ball cup assembly 2, and a snap-fit ​​assembly 3. The handle body 1 has an accessory cavity 11, the snap-fit ​​assembly 3 is installed in the accessory cavity 11, and the ball cup assembly 2 is installed in the handle body 1 to encapsulate the snap-fit ​​assembly 3 in the accessory cavity 11. The two ends of the accessory cavity are open for button access.

[0026] The snap-fit ​​assembly 3 includes a threaded component 4 and a button 5. The threaded component 4 includes a first threaded component 41 and a second threaded component 42, which are arranged opposite to each other. The button 5 includes a first button 51 and a second button 52, which are also arranged opposite to each other. The first threaded component 41, the second threaded component 42, the first button 51, and the second button 52 are arranged in a ring-like manner. The first threaded component 41 and the second threaded component 42 are spaced apart to form a plug-in position 12 between them.

[0027] Button 5 abuts against threaded component 4, and threaded component 4 is pushed by button 5 to change the size of insertion position 12; threaded component 4 is provided with a first spring 43, and the first spring 43 abuts against the wall of accessory cavity 11 to assist threaded component 4 in resetting. Further, threaded component 4 is provided with a first inclined surface 44, and button 5 is provided with a second inclined surface 53, the first inclined surface 44 and the second inclined surface 53 are in contact; button 5 moves relative to threaded component 4, and changes the position of threaded component 4 in accessory cavity 11 by sliding and pressing the first inclined surface 44 and the second inclined surface 53.

[0028] The ball cup assembly 2 includes a lower ball cup 21 and an upper fixing seat 22. The upper fixing seat is fixed to the handle body by screws. The lower ball cup 21 has a shaft hole 23. The upper end face of the upper fixing seat 22 is provided with a protruding shaft post 24. The shaft post 24 is connected to the shaft hole 23 to assemble the lower ball cup 21 and the upper fixing seat 22 together. The shaft post 24 is provided with an annular groove 25 and a retaining spring 26. When the lower ball cup 21 is connected to the upper fixing seat 22, the shaft post 24 protrudes out of the shaft hole 23. The retaining spring 26 is connected to the annular groove 25 to prevent the upper fixing seat 22 from disengaging from the lower ball cup 21. The shaft post 24 has a through hole, which is located on the same axis as the shaft hole 23 to allow the insertion rod to pass through the ball cup assembly 2 and enter the accessory cavity 11.

[0029] The first threaded component 41 and the second threaded component 42 have the same structure as the threaded component 4, only their placement differs. The threaded component 4 includes a safety buckle 6 and a locking block 7. The locking block 7 has an arc 71 with threads. The safety buckle 6 is located at the upper and lower ends of the locking block 7. The safety buckle 6 has a locking position 61, and the locking block 7 has a recess 72. The button 5 extends a locking strip 54, and the safety buckle 6 connects to the recess 72, so that the locking position 61 is higher than the end face of the locking block 7 for the locking strip 54 to be inserted into the locking position 61. The safety buckle 6 has a second spring 62, which abuts against the upper fixing seat 22 to keep the safety buckle 6 connected to the locking block 7 and the button 5, thereby limiting the range of movement of the locking block 7 and the button 5. The accessory cavity 11 has a stop bar 13, and the button 5 has a third spring 55, which connects to the stop bar 13 to assist the button 5 in resetting. The locking strip 54 has an upper inclined surface 56, which abuts against the end face of the locking position 61 of the safety buckle 6. The button 5 moves relative to the safety buckle 6 so as to change the position of the safety buckle 6 by pressing the upper inclined surface 56 against the end face of the locking position 61.

[0030] Most ball-handle cup fixing methods on the market currently use handle screws and bolts, which require turning the handle many times each time to fix or loosen the cup, making operation inconvenient. To improve ease of use, we propose a quick-release handle solution for tripod ball-handle cup fixing.

[0031] In this design, the accessory cavity 11 is equipped with two locking blocks 7, one on the left and one on the right. The locking blocks 7 have threads corresponding to the screw of the ball cup assembly. The threads on the left and right locking blocks 7 are asymmetrical, forming a complete thread track. After the ball cup assembly is installed into the three-section seat, align the handle with the screw and press the buttons 5 on both sides. The inclined surface 56 on the button 5 pushes the four safety latches 6 to move up and down respectively. When the button 5 reaches a certain travel distance, the safety latches 6 completely disengage from the left and right thread locking blocks 7. The button 5 continues to push forward. After the safety latches 6 are unlocked, the inclined surfaces on the left and right buttons 5 begin to push the left and right locking blocks 7 to move to the left and right respectively, and the threads move backward. At this time, the screw can be quickly inserted. After the screw is in place, release the button 5. Due to the action of the spring, the button 5 returns to its original position, the left and right locking blocks 7 return to their original position, the threads lock the screw threads, and the four safety latches 6 return to their original position, locking the left and right locking blocks 7. Then, rotate the handle slightly to lock the screw threads. When disassembly is required, rotate the handle counterclockwise half a turn, press and hold buttons 5 on both sides, and repeat the above actions for each part to quickly remove the handle.
