The drive assembly 32 includes a first electric push rod 321 and a second electric push rod 322. The first end of the first folding arm 311 is hinged to the movable base 2. Specifically, the movable base 2 is provided with a first support 25. The first end of the first folding arm 311 is hinged to the first support 25 via a pivot pin, allowing the first folding arm 311 to rotate toward or away from the movable base 2. The first end of the third folding arm 313 is hinged to the second end of the first folding arm 311 via a second support 26, allowing the third folding arm 313 to rotate toward or away from the first folding arm 311. The second end of the third folding arm 313 is hinged to the first end of the fourth folding arm 315, and the ball-serving machine frame 11 is mounted on the third folding arm 313. Please continue to refer to... Figure 4In the figure, the first end of the second folding arm 312 can move back and forth on the movable base 2 from left to right. Specifically, the base 21 is a hollow structure with a guide rail (not shown) inside. The first end of the second folding arm 312 is equipped with a pulley that matches the guide rail, allowing it to roll along the guide rail. Alternatively, the first end of the second folding arm 312 can be equipped with a slider, linear bearing, etc., allowing it to slide along the guide rail. A first electric push rod 321 is connected between the first end of the first folding arm 311 and the second end of the second folding arm 312. A second electric push rod 322 is connected between the second end of the fourth folding arm 315 and the second end of the first folding arm 311. It should be noted that, in order to facilitate folding and storage and save space, the first folding arm 311 includes two structural rods 311'. The two structural rods 311' are arranged side by side and rotate synchronously. A fixed gap is left between the two structural rods 311'. The first electric push rod 321 and the second electric push rod 322 are provided within this fixed gap for easy storage. It should be noted that the folding lifting mechanism 3 is also equipped with a telescopic handle 6. The telescopic handle 6 is connected to the first folding arm 311 and is temporarily fixed to the folding lifting mechanism 3 by a buckle. When it needs to be moved, the telescopic handle 6 can be released and adjusted to a suitable position as a handle for pulling the entire device.

[0032] Please combine Figure 1 , Figure 4 and Figure 5 In actual use, when the first electric push rod 321 and the second electric push rod 322 are in the reset state, refer to Figure 5 In the middle section, the third folding arm 313 is parallel to and attached to the first folding arm 311, and the second folding arm 312 and the fourth folding arm 315 are as close as possible to the first folding arm 311. The first electric push rod 321 and the second electric push rod 322 are located within a fixed distance between the two structural members, so that the lifting folding bracket 31 can be folded flat, resembling a straight structure, saving space and facilitating storage. When the device of the present invention is used for serve training, the first electric push rod 321 and the second electric push rod 322 are powered on and activated, as shown in the reference section. Figure 4In the process, the first electric push rod 321 pushes the second end of the second folding arm 312, causing the first end of the second folding arm 312 to slide onto the movable base 2. The second folding arm 312 pushes the first electric push rod 321 to rotate around the support 25 in a direction away from the movable base 2, thereby lifting it. As the first electric push rod 321 continues to push, the first folding arm 311 and the second folding arm 312 support each other in an X-shape until the height of the serving device 1 is adjusted. The second electric push rod 322 pushes and pulls the second end of the fourth folding arm 315, thereby lifting the fourth folding arm 315. The first end of arm 315 pushes and pulls the third folding arm 313. The third folding arm 313 rotates around the support 26 to rotate toward or away from the first folding arm 311, driving the ball-serving machine frame 11 to rotate synchronously until the ball-serving tilt angle of the ball-serving device 1 is adjusted. With the help of the horizontal adjustment wrench (not shown) on the ball-serving device 1, the horizontal launch angle can be adjusted. After the device is used up, the first electric push rod 321 and the second electric push rod 322 return to the reset state and are flattened into a straight structure for easy storage and space saving.

[0033] In this invention, the control system can control the overall start and stop of the device, and also control the lifting mechanism 3 to achieve automatic adjustment. That is, through the communication commands of the control system, the first electric push rod 321 and the second electric push rod 322 can reach the appropriate length, thereby automatically and accurately adjusting the height and launch tilt angle. In addition, the control system adjusts the launch ball speed by controlling the power of the motor 13.

[0034] Please continue to refer to this. Figure 1 and Figure 2 The invention also includes an electrical control box 7, which contains operating components for the control system (not shown). The electrical control box 7 has an electronic display screen showing the ball's speed and is equipped with various control buttons or knobs.
