Firstly, the user steps on the actuating element, i.e. steps on the pedal assembly 13, pulls the locking pin 11 to retract the sleeve 12 through the wire-pulling device 7, and compresses the return spring; at this time, the locking pin 11 no longer has a stopping function on the blocking portion 211, and under the elastic restoring force of the elastic actuating member 22, the first connecting lug 212 slides along the first abutting point 361 of the avoiding groove 36 to the second abutting point 362, so that the blocking piece 21 rotates relative to the rotating shaft 41, and the blocking portion 211 blocks the first locking hole 33. Then, the user releases the footrest assembly 13, and the locking pin 11 abuts against the blocking portion 211 by the elastic restoring force of the return spring, but does not pass through the first locking hole 33, so that the armrest column rotary plate 3 is always maintained in the unlocked state. Finally, the user can lift the treadmill handrail post 6 in the folded state so that the locking pin 11 leaves the blocking portion 211 and slides along the second side 32 of the handrail post rotating disk 3 to the second locking hole 34, and the treadmill handrail post 6 is locked in the unfolded state.

The folding process of the treadmill handrail column 6 is as follows: in the initial state, the treadmill handrail 6 is in the unfolded state, and at this time, the locking pin 11 is in locking engagement with the second locking hole 34, the blocking portion 211 of the blocking member 2 is blocked at the first locking hole 33, the first connecting lug 212 of the blocking member 2 is located at the second abutting point 362 of the abdicating groove 36 of the handrail column rotating disc 3, and the elastic actuating member 22 is in the natural state.

Firstly, the user steps on the actuating element, i.e. steps on the pedal assembly 13, pulls the locking pin 11 to retract the sleeve 12 through the wire-pulling device 7, and compresses the return spring; at this time, the user can slightly push the unfolded treadmill handle by hand, so that the handle post drives the handle post turntable 3 to rotate, and the locking pin 11 is dislocated with the second locking hole 34; then, the user can release the pedal assembly 13, and the locking pin 11 abuts against the second side surface 32 of the armrest column rotary disc 3 under the elastic restoring force of the return spring; then, the user can continue to rotate the handrail column from the convenient orientation so that locking pin 11 slides on second side 32 of handrail column rotating disk 3 to abut against the edge of blocking portion 211 of blocking piece 21, and during the user continues to rotate treadmill handrail column 6, locking pin 11 will push blocking portion 211 to gradually open first locking hole 33 until locking pin 11 is fully inserted into first locking hole 33, during which the rotation of blocking portion 211 causes first connecting lug 212 to slide along second abutting point 362 of avoiding groove 36 to first abutting point 361, so that resilient actuating member 22 is again in the stretched state.
