发明名称 Hand-held volleyball spiking trainer device
摘要 A volleyball spiking practice device positions a volleyball at a desired elevation above a surface. The device comprises a generally C-shaped head and a support pole attached to the head. The head sufficiently retains a volleyball to be knocked free. The support pole is attached with the head at an angle so that the support pole extends laterally away from the head when vertically disposed, to position the volleyball. The support pole is hand-held.
