Description
Technical field [0001] The invention relates to a kind of throwing equipment of special sports equipment, especially a table tennis ball serving device. Background technique [0002] At present, the table tennis ball serving device on the market has multiple structures, and the most representative one is a kind of ball serving device disclosed by CN86101172A. There is a ball inlet at the other end, and the inlet is connected with the conveying path. The feeding device sends the ball entering the conveying path into the head structure, and throws the ball from the outlet in the head through the throwing device. The throwing device It includes a friction wheel rotatably installed on the shell and an elastic friction block supporting the ball. The ball storage mechanism of this ball serving device is a grasping structure, which often breaks the ball. The manufacturing process of the friction wheel is complicated. The wheel hub and the friction rubber in the friction system are...
