[0005] To further refine the above technical solution, the inner wall of the ball head sleeve is provided with several circular pits.

[0006] Further refining the above technical solution, each push rod is a spring push rod, and a slider cavity is provided inside the ball head. Each push rod extends into the slider cavity, and a slider is placed inside the slider cavity with its front end facing each push rod and the contact surface being a wedge surface. The round-headed slider moves axially, causing each push rod to extend out of or retract from the ball head.

[0007] Further refining the above technical solution, a rod is installed on the ball head, the rear end of the slider is opposite to the rod and the contact surface is a wedge surface, and a return spring A is installed at the front end of the slider; the rod moves radially and cooperates with the return spring A to make the slider move axially.

[0008] Further refining the above technical solution, the rod is shaped like a tall goblet, on which a return spring B and upper and lower limits are installed. The rod, return spring B, and upper and lower limits together form a button.

[0009] Further refining the above technical solution, the button is rotary, with a rotary handle installed on it.

[0010] Further refining the above technical solution, the ball head sleeve is composed of two hemispherical ball head sleeves connected together.

[0011] The advantages of this utility model are that it has a reasonable design, simple structure, and can achieve multi-directional and large-angle adjustment. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the ball head sleeve structure.

[0014] The figure includes: ball head sleeve 1, circular recess 1-1, hemispherical sleeve 1-2, ball head connecting part 2, ball head 3, push rod 4, slider cavity 5, slider 6, rod 7, return spring A 8, return spring B 9, upper and lower limit 10, and rotating handle 11. Detailed Implementation

[0015] like Figure 1-2 As shown, a fixed connection device with a large rotation angle is provided. The fixed connection device consists of a ball head sleeve 1 and a ball head connecting component 2. A ball head 3 is provided on the ball head connecting component 2. The ball head 3 is placed inside the ball head sleeve 1. Several push rods 4 are installed inside the ball head 3. Each push rod 4 is centered and evenly distributed around the central axis of the ball head 3. Each push rod 4 is a spring push rod. A slider cavity 5 is provided inside the ball head 3. Each push rod 4 extends into the slider cavity 5. A slider 6 is placed inside the slider cavity 5. Its front end is opposite to each push rod 4 and the contact surface is a wedge surface. A rod 7 is installed on the ball head 3. The rear end of the slider 6 is opposite to the rod 7 and the contact surface is a wedge surface. A return spring A 8 is installed at the front end of the slider 6. The rod 7 is cup-shaped. A return spring B 9 and upper and lower limiters 10 are installed on it. The rod 7 and the return spring B 9 are... 9. The upper and lower limit switches 10 form a button; the button is rotary and a rotary handle 11 is installed on it; the inner wall of the ball head sleeve 1 is provided with several circular pits 1-1; the ball head sleeve 1 is composed of two hemispherical head sleeves 1-2 connected together. When fixing the ball head 3: Press the rotating handle 11, the rod 7 moves radially, causing the slider 6 to move axially; the slider 6 moves axially, causing each push rod 4 to extend out of the ball head and tighten on the inner wall of the ball head sleeve 1; rotate the rotating handle 11 to lock; When the ball head is released: rotate the handle 11 to release the lock; under the action of the return spring B 9, the rod 7 moves radially; under the action of the return spring A 8, the slider 6 moves axially; each push rod 4 retracts into the ball head 1 under the action of its spring.
