The following description of the embodiments with reference to the drawings is exemplary and intended to explain the present invention, but cannot be understood as limiting the present invention.

[0025] The preferred embodiment provided by the present invention is as follows: Figure 1 to Figure 4 As shown, a tripod ball bowl fixed quick-release handle includes a handle body 1, a ball bowl assembly 2, and a clamping assembly 3; the handle body 1 is provided with an accessory cavity 11, the clamping assembly 3 is installed in the accessory cavity 11, and the ball bowl assembly 2 is installed in the handle body 1 to encapsulate the clamping assembly 3 in the accessory cavity 11; both ends of the accessory cavity are open for button access.

[0026] The clamping assembly 3 includes a screw member 4 and a button 5. The screw member 4 includes a first screw member 41 and a second screw member 42, and the first screw member 41 and the second screw member 42 are arranged opposite to each other. The button 5 includes a first button 51 and a second button 52, and the first button 51 and the second button 52 are arranged opposite to each other. The first screw member 41, the second screw member 42, the first button 51 and the second button 52 are arranged in a surrounding manner, and the first screw member 41 and the second screw member 42 are separated so that a plug-in position 12 is formed between the first screw member 41 and the second screw member 42.

[0027] The button 5 is in contact with the screw thread 4, and the screw thread 4 is pushed by the button 5 to change the size of the plug-in position 12; the screw thread 4 is provided with a first spring 43, and the first spring 43 is in contact with the wall of the accessory cavity 11 to assist the screw thread 4 in resetting. Further, the screw thread 4 is provided with a first inclined surface 44, and the button 5 is provided with a second inclined surface 53, and the first inclined surface 44 is connected with the second inclined surface 53; the button 5 moves relative to the screw thread 4, and the position of the screw thread 4 in the accessory cavity 11 is changed by sliding and squeezing the first inclined surface 44 and the second inclined surface 53.

[0028] The bowl assembly 2 includes a lower bowl 21 and an upper fixing seat 22. The upper fixing seat is fixed to the handle body by screws. The lower bowl 21 has an axial hole 23. The upper end surface of the upper fixing seat 22 is provided with a protruding shaft column 24. The shaft column 24 is connected to the shaft hole 23 to assemble the lower bowl 21 and the upper fixing seat 22 together. The shaft column 24 is provided with an annular groove 25. The shaft column 24 is equipped with a retaining spring 26. The lower bowl 21 is connected to the upper fixing seat 22 so that the shaft column 24 protrudes from the shaft hole 23. The retaining spring 26 is connected to the annular groove 25 to limit the upper fixing seat 22 from being separated from the lower bowl 21. The shaft column 24 has a through hole. The through hole and the shaft hole 23 are located on the same axis so that the rod can pass through the bowl assembly 2 and enter the accessory cavity 11.

[0029] The structures of the first screw thread member 41 and the second screw thread member 42 are the same as the screw thread member 4, and the two are only placed in different positions. The screw thread member 4 includes a safety buckle 6 and a locking block 7, and the locking block 7 is provided with an arc position 71, and the arc position 71 is provided with a screw thread; the safety buckle 6 is respectively arranged at the upper and lower ends of the locking block 7. The safety buckle 6 is provided with a clamping position 61, and the locking block 7 is provided with a concave position 72. The button 5 extends a clamping strip 54, and the safety buckle 6 is connected to the concave position 72, so that the clamping position 61 is higher than the end surface of the locking block 7 so that the clamping strip 54 can be inserted into the clamping position 61. The safety buckle 6 is provided with a second spring 62, and the second spring 62 of the safety buckle 6 abuts against the upper fixed seat 22 to drive the safety buckle 6 to remain connected with the locking block 7 and the button 5, so as to limit the moving range of the locking block 7 and the button 5. The accessory cavity 11 is provided with a stop bar 13, and the button 5 is provided with a third spring 55, and the third spring 55 of the button 5 is connected with the stop bar 13 to assist the button 5 in resetting. The clamping strip 54 is provided with an upper inclined surface 56 , which abuts against the end surface of the clamping position 61 of the safety buckle 6 . The button 5 and the safety buckle 6 move relative to each other to change the position of the safety buckle 6 by squeezing the upper inclined surface 56 and the end surface of the clamping position 61 against each other.

[0030] Currently, most bowl fixing methods on the market use handle screws and screws. Each time the handle is fixed and loosened, it is necessary to turn the handle many times, which is inconvenient to operate. In order to improve the convenience of operation, we proposed a tripod bowl fixing quick-release handle solution.

[0031] In this solution, the accessory cavity 11 is provided with two left and right locking blocks 7, and the locking blocks 7 have screw threads corresponding to the screw rod of the ball bowl assembly. The screw threads on the left and right locking blocks 7 are asymmetrical and can just form a circle of screw thread tracks. When the ball bowl assembly is installed in the three-cut seat, the handle is aligned with the screw rod, and after pressing the buttons 5 on both sides, the inclined surface 56 on the button 5 pushes the four upper, lower, left and right safety buckles 6 to move up and down respectively. When the button 5 reaches a certain stroke, the safety buckle 6 completely disengages from the left and right screw thread locking blocks 7, and the button 5 continues to push forward. After the safety buckle 6 is 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 screw threads move backward. At this time, the screw rod can be quickly inserted. After the screw rod is in place, the button 5 is released. 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, and the screw threads clamp the screw rod teeth. The four safety buckles 6 return to their original positions and clamp the left and right locking blocks 7. At this time, the handle is slightly rotated again, and the screw threads lock the screw rod. When disassembly is required, rotate the handle counterclockwise half a turn, press and hold the buttons 5 on both sides, and repeat the above steps for each part to quickly remove the handle.

[0032] In the description of the specification, the description with reference to the terms "one embodiment", "preferably", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present invention. The schematic expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. Through the description of the above structure and principle, those skilled in the art should understand that the present invention is not limited to the above-mentioned specific embodiments, and improvements and substitutions based on the present invention using the known technology in the art fall within the scope of protection of the present invention and should be defined by the claims.
