Problems solved by technology

[0003] The barbell bar of the prior art has the following disadvantages: there is a gap between the barbell plate and the barbell bar, and the barbell plate needs to be fixed by a clamp in advance. , falling from a higher place, the belayer's inattention, the belayer's strength is small, etc.), it must be carried out in cooperation between the trainer and the belayer, so that the barbell cannot be used alone

[0004] And most of the existing barbells need to be used with the help of barbell plates, but there is no corresponding magnetic resistance to realize the function of replacing the barbell plates, and in the existing equipment, if the barbell falls due to lack of physical strength, it still needs The surrounding personnel manually remove the barbell plate, which cannot realize the function that a single person can push the barbell plate out of the barbell
