The spring 18 pulls the fixing plate 19, and the sliding rod 17 moves the footrest 15, causing the locking rod 21 to insert into the locking hole 20, preventing the footrest 15 from moving arbitrarily and affecting normal operation. When a person becomes exhausted and the barbell presses against their chest, they can push the foot pedal 15 with their feet to disengage the locking lever 21 from the locking hole 20, allowing the foot pedal 15 to unlock quickly. Moving the feet forward pushes the lever 16, and the foot pedal 15 moves the inner moving box 13 and the outer moving box 11 via the sliding lever 17. The outer moving box 11 drives the connecting gear 10 to rotate via the rack 12, and the second bevel gear 9 rotates, driving the first bevel gear 2 to rotate, causing the rotating block 3 to rotate. The connecting rod 6 rotates to the vertical direction, and the support pad 7 pushes and supports the barbell, thus protecting the person.
