Problems solved by technology

[0004] The table tennis exerciser on the market mainly is by two kinds of forms, and the first is to be connected successively by a table tennis ball, an elastic soft rod and a base and forms, and this table tennis exerciser is owing to not needing table tennis table, occupies It is small in size, light and flexible, and cheap in price. Thousands of individuals and families who like to practice table tennis want to own it. However, after many individuals and families buy this kind of table tennis training device, their interest will be greatly reduced after playing for a few days. , basically idle on one side, because there are two shortcomings in the current table tennis training device, the one is because the table tennis ball is only connected with a very thin elastic soft rod. Under the traction of the soft rod, in addition to moving forward, it also shakes irregularly in the left and right directions, which makes it difficult for the practitioner to control and cannot continue to swing and hit the ball, especially for those beginners and the elderly who play table tennis at home for entertainment and fitness People are even more difficult to control this table tennis that shakes from side to side, so it is easy to make buyers lose interest in practice and entertainment; the second is that when the elastic soft rod bends under the action of force, it will produce its own elastic force to return to a straight line, and, The greater the bending deformation, the greater the elastic force to restore the straight line, so when the user hits the ball vigorously, the rebound force is also greater, so the greater the force of the impact, the faster the rebound speed of the table tennis ball. It is too late to hit the rebounding ball. To put it simply, the table tennis ball is too fast to hit the ball.

[0005] Since the second type is composed of a rotatable ball head, a small section of spring (or other elastic material), a relatively fixed rod or shaft and base (or things like suction cups or clips), the table tennis ball of this structure The exercise device, the distance of the table tennis back and forth is very short, and the table tennis is basically in a fixed position. It feels very rigid to practice, and it does not simulate the feeling of actually playing table tennis. Therefore, it is easy for the practitioners and entertainers to lose interest.
