[0025] Specifically, the first card block 8 is engaged with the first card slot 4.

[0026] Furthermore, a control lever 9 is fixedly connected to the front surface of the first locking block 8, and a first handle 10 is fixedly connected to the other end of the control lever 9 for controlling the first locking block 8, thereby facilitating the adjustment of the position of the controller 13.

[0027] Furthermore, the second card block 16 engages with the second card slot 14, and the second card block 16 slides with the slider 3.

[0028] It is worth noting that a connecting rod 17 is fixedly connected to the left surface of the second locking block 16, and a second handle 18 is fixedly connected to the other end of the connecting rod 17 for controlling the second locking block 16, thereby facilitating the adjustment of the angle of the controller 13.

[0029] It is worth noting that the front surface of the slide box 2 is provided with a side slot 19, and the control rod 9 is slidably connected to the side slot 19 for sliding.

[0030] It is worth mentioning that the top surface of the sliding box 2 is provided with an upper slot 20, and the connecting bracket 12 and the second handle 18 are slidably connected to the upper slot 20.

[0031] It is worth emphasizing that both the side slot 19 and the top slot 20 are equipped with flexible plates to reduce the entry of foreign objects into the slotted box 2.

The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle: When adjusting the position of controller 13, the first handle 10 pulls the control lever 9, which in turn pulls the first locking block 8. The first locking block 8 is pulled and compresses the first spring 7, causing it to move backward. This allows the first locking block 8 to slide back from the first slot 4 into the slider 3. Then, the controller 13 can be pushed to adjust its position. When the first handle 10 is released, the first spring 7 applies elastic force to the first locking block 8, causing it to pop out and slide within the rectangular slot 5. The first locking block 8 then slides out of the slider 3 and engages with the corresponding first slot 4, thus fixing the position of the slider 3 and consequently fixing the position of the controller 13. When the angle of controller 13 needs to be adjusted, the connecting rod 17 is pulled by the second handle 18. The connecting rod 17 pulls the second locking block 16. The second locking block 16 is pulled and compresses the second spring 15, causing it to move backward and slide out of the rotating seat 11. Then, the controller 13 can be rotated to adjust the angle of controller 13. After the adjustment is completed, the second handle 18 is released. The second spring 15 applies elastic force to the second locking block 16, causing the second locking block 16 to pop out and slide into the corresponding second slot 14 in the rotating seat 11, thereby fixing the position of the rotating seat 11 so that the rotating seat 11 cannot rotate, and thus fixing the angle of controller 13.
