Description

technical field [0001] The invention relates to the field of martial arts training equipment, in particular to a device for electrically adjusting the height of a cross bar for leg pressing. Background technique [0002] In schools such as martial arts and dancing, the leg press training is to place the feet or legs on a cross bar of a certain height for leg press training, but because the height of the cross bar is fixed, the height of the cross bar is not the same for many people. It must be suitable, because everyone's height, physical fitness, training level etc. are not the same, which affects the improvement of some people's leg press training level, and there is no electric device that can conveniently adjust the height of the leg press bar. For this reason, design a kind of device that can conveniently adjust the height of the crossbar for leg pressing, which can enable the trainer to determine the height of the crossbar according to his own conditions and level, and...
