Abstract

The invention discloses a table tennis ball launcher, comprising a base, a first motor, a support and a ball storage box which is fixedly arranged on the support. The base is provided with a launching tube and a ball admission tube which are communicated with each other, and the ball admission tube is communicated with the ball storage box by a connection hose. The table tennis ball launcher is characterized in that the base is provided with a first inner chamber, the first inner chamber is intercommunicated with the ball admission tube by a falling hole, an output shaft of the motor extends into the first inner chamber and is provided with a launching bat for beating table tennis balls; the base is provided with at least one roller, and the roller is provided with a depth regulating device. The table tennis ball launcher has the advantage that as the output shaft of the first motor is provided with the launching bat and the base is provided with the roller, when the launching bat passes through the roller in a rotation manner, the launching bat is pressed backwards, and when the launching bat is separated from the roller, and he table tennis balls falling into the falling hole are bounced by rebounding of the launching bat, and the roller is provided with the depth regulating device which can regulate the depth of the roller extending into the first inner chamber, so as to regulate force of launching the table tennis balls by controlling bound force of the launching bat.

Description

technical field [0001] The invention relates to a table tennis auxiliary exercise device, in particular to a table tennis launcher. Background technique [0002] Table tennis is our national sport in China, and it is very popular in national sports, but athletes can achieve impressive results in international competitions and their usual training is inseparable. Athletes basically rely on two people to practice against each other in training. The strength of the two sides is different. Athletes with good skills may not be able to achieve the training effect they want, and the training time needs to be arranged by two people. Not free in time either. In order to solve this problem, people have invented a table tennis launcher, which can be used to practice catching the ball by oneself, which is more convenient and free, but the existing table tennis launcher has a complicated structure, and the direction of serving is single, and the variability is not good. powerful. Con...
