When the barbell falls out of control, the spring sheet 1 and the spring sheet 2 rotate relative to each other through the hinge shaft and deform, which can effectively absorb the impact force of the falling barbell and reduce potential damage to the user. At the same time, the rebound after deformation can drive the relevant components to reset, ensure the repeated use of the buffering function, and provide a basis for the safe use of the equipment.

[0007] Furthermore, the height adjustment part includes an adjustment component, which is arranged above the base plate; and a power component, which is installed on the Smith bird fly stand.
