Description

Technical Field

[0001] The utility model relates to the field of badminton training equipment, in particular to a novel hitting training device. Background Art

[0002] Sports such as badminton and table tennis can have a good whole-body exercise effect, but badminton and table tennis are both competitive sports, and generally require two or more people to conduct competitive training. When there is only one person, you need to prepare multiple badminton or table tennis balls at the same time, collect them all after playing, and then repeat the training. Picking up the balls takes a lot of time and physical strength, which reduces the training effect. Therefore, a training device that can automatically recycle badminton has appeared in life. The principle is to set an elastic rope on the badminton, and set a motor at one end of the elastic rope. The motor pulls the badminton back to its original position, eliminating the process of manually collecting the badminton. However, when using this trainer, the elastic rope is prone to winding around the motor, causing the motor to fail to work properly, affecting the normal use of the trainer. Utility Model Content
