[0033] When using this sports volleyball interval serving device, first install the device at one end of the stadium, pour the volleyball into the serving machine 11, and have the user hold the pull member 13 to move the support platform 12 outward. The support platform 12 will then move the two guide tubes 17 outward as well, thus stretching the first multi-section telescopic rod 16 and the first telescopic member 111. Next, control the extension of the multi-section electric push rod 15 to move the support frame 151 forward, causing the front end of the second telescopic tube 18 to extend forward, stretching it to the other end of the serving machine 11. This way, when the user receives the ball, they are also positioned at the other end of the serving machine 11.
