The Chinese patent with application number 201620594725.2 discloses a volleyball net frame for spike training. Between the volleyball posts, a counterweight is provided at the bottom of the left volleyball post and the right volleyball post, and it is characterized in that: the left volleyball post and the right volleyball post are arranged in a hollow structure, and a telescopic device is respectively arranged inside the volleyball post. The top of the telescopic device is provided with a suspension ring, and a connecting rope is arranged between the left and right suspension rings, and a training volleyball is arranged on the connecting rope. After adopting the above-mentioned structure, the training ball is just above the volleyball net, and its up, down, left and right positions can be adjusted. When practicing one-person-one-ball spiking, there is no need to pick up the ball, which saves manpower, material resources, time, and increases training time. The number of times, the practitioner can perform spiking practice from different heights and left and right positions, which is conducive to the development of volleyball.
