[0040] Example 1

[0041] like Figure 1-Figure 10As shown, this embodiment provides a tripod device, including an upper slide 1 and a lower slide 2, the lower slide 2 including a slide rail 21, the slide rail 21 is inserted into the slide groove 11 of the upper slide 1; the slide rail 21 is connected to a movable sheet 22, and a fixed ball 23 is fixedly connected to the movable sheet 22; the upper slide 1 is provided with a plurality of positioning grooves 12, and the fixed ball 23 is adapted to the positioning groove 12; when the slide rail 21 moves relative to the slide groove 11, the movable sheet 22 is used to drive the fixed ball 23 to engage with different positioning grooves 12 to adjust the position of the lower slide 2.

[0042] The upper slide 1 is located outside the lower slide 2, and the upper slide 1 has the same or similar shape as the lower slide 2. A slide rail 21 is provided on the outer side of the lower slide 2, and a slide groove 11 is provided on the inner side of the upper slide 1, and the slide rail 21 fits with the slide groove 11. The upper slide 1 is placed first, and then the slide rail 21 of the lower slide 2 is inserted into the slide groove 11 of the upper slide 1.

[0043] A fixed ball 23 is disposed inside the movable sheet 22, and the fixed ball 23 is fixedly connected to the movable sheet 22, for example, the fixed ball 23 is embedded inside the movable sheet 22. The movable sheet 22 is pressed, and the movable sheet 22 and the fixed ball 23 move in a direction away from the upper slide 1, so that the fixed ball 23 is disengaged from the positioning groove 12. At this time, the movable sheet 22 is slid along the extension direction of the slide rail 21. When the movable sheet 22 is located at a preset position, the movable sheet 22 is released, and the movable sheet 22 and the fixed ball 23 move in a direction close to the upper slide 1, so that the fixed ball 23 is inserted into the corresponding positioning groove 12.

A plurality of positioning grooves 12 are arranged at intervals on the upper slide 1, and the spacing between adjacent positioning grooves 12 is equal to the spacing between two fixed balls 23. The relative positions of the fixed balls 23 and the movable sheet 22 remain unchanged, and the movable sheet 22 has a certain elasticity. Pressing the movable sheet 22 disengages the two fixed balls 23 from the corresponding two positioning grooves 12, and sliding the movable sheet 22 along the slide rail 21 can quickly adjust the length of the tripod. Loosening the movable sheet 22 allows the two fixed balls 23 to be inserted into the corresponding two positioning grooves 12, thereby fixing the upper slide 1 and the lower slide 2.
