Referring to fig. 2 and 7, a sensor 24 is fixed to a side end surface of the supporting block 26 near the user's use standing position, and the sensor 24 is used for recognizing the user's posture.

In the initial state, the stop limit block 13 is intact, the emergency reaction block 12 abuts against the connecting rod 28, the pressure regulation block 22 is inserted into the hinge block 23, the protective blanket 38 is lapped on one side of the suspension limit rod 39 far away from a user, the buffer spring 45 and the elastic spring 42 are in the normal state and are not stretched or compressed, the sliding block 33 abuts against the impact block 36, the electromagnet 34 is not electrified, and the locking block 35 is inserted into the impact block 36 to limit the impact block 36 to slide.

When the user normally uses, the user inserts the bolt 21 and extracts the back from articulated block 23 according to self height, pull up supporting shoe 26, adjust to and insert the bolt 21 with the locking again in articulated block 23 and restrict pressure regulating block 22 and remove this moment after suitable height, the space that pressure regulating block 22 and articulated block 23 are constituteed increases, thereby atmospheric pressure reduces, the space that gas passes through gas communicating pipe 20 entering pressure regulating block 22 and articulated block 23 and constituteing in sealed room 29 this moment, thereby make closing plate 27 drive connecting rod 28 to remove to the direction of keeping away from emergency reaction block 12, then the user manually removes emergency reaction block 12 to the direction of being close to connecting rod 28, make it can with connecting rod 28 butt, be used for adjusting the relative user's of protection blanket 38 this moment distance.

When the user starts using the treadmill 1, the auxiliary handle 25 is held by both hands, and the auxiliary handle 25 swings the hinge block 23 via the support block 26 and the pressure adjustment block 22 in sequence.

When the user suddenly slips down by using the treadmill 1, the sensor 24 recognizes that the user rapidly falls down and inclines forwards, at this time, the electromagnet 34 is electrified, the locking block 35 is adsorbed, the locking block 35 is pulled out from the impact block 36, the impact block 36 is out of the limited state, and rapidly pops up downwards under the action of the impact spring 37, and rapidly pushes the sliding block 33 downwards, so that the sliding block 33 is accelerated in a short time, the movable extension block 32 is driven to rapidly slide in the sliding groove 31, the speed of acceleration of the sliding block 33 in a short time is enough to enable the movable extension block 32 to slide to the other end of the sliding groove 31, finally the movable extension block 32 slides to the other end of the sliding groove 31 to be stopped, at this time, the movable extension block 32 and the fixed extension block 30 jointly unfold the protection blanket 38 completely, and in the sliding process of the movable extension block 32, the buffer block 40 is pressed downwards when passing through the buffer block 40, at this time, the elastic spring 42 is compressed by the connecting block 41.

After the protection blanket 38 is unfolded, the protection blanket 38 gradually falls on the protection blanket 38, and the protection blanket 38 is squeezed, so that the protection blanket 38 blocks the upper body of the user, at this time, when the weight of the user is light, the protection blanket 38 acts on the hinged part of the emergency reaction block 12 after blocking the upper body of the user, so that the emergency reaction block 12 rotates towards the direction close to the stop limiting block 13 by taking the hinged part as an axis, but at this time, the stop limiting block 13 limits the rotation of the emergency reaction block 12, so that the stop limiting block 13 is stressed, and the stop limiting block 13 is not damaged because the weight of the user is light at this time.

When the user's weight is heavier, the locking stopper 13 is deformed and destroyed due to an excessive force, at this moment, the emergency reaction block 12 rotates towards the direction close to the locking stopper 13 by taking the hinge portion as the axis, at this moment, the trend of the sliding groove 31 is changed from approximately horizontal to vertical, at this moment, the protection blanket 38 drives the movable extension block 32 to move towards the direction close to the fixed extension block 30 under the action of the gravity of the user, at this moment, the movable extension block 32 abuts against the buffering fixture block 40, the buffering fixture block 40 drives the fixture block limiting box 43 to move towards the direction far away from the locking stopper 13 through the connecting block 41, and drives the buffering fixture block 44 to move towards the direction far away from the locking stopper 13, at this moment, the buffering spring 45 is gradually compressed, thereby further buffering the user upside down, and further protecting the safety of the user.

When the buffering fixture block 40 continuously moves in the sliding groove 31 in the direction close to the fixed extension block 30, due to the shape of the sliding groove 31, the track of the sliding groove 31 is upward, so that the buffering fixture block 40 is gradually separated from the movable extension block 32 to be abutted, after the buffering fixture block is separated from the connection, the movable extension block 32 continuously slides to the initial position close to the end of the fixed extension block 30, at the moment, the sliding block 33 is abutted to the impact block 36 and presses the impact block 36 into the initial position, at the moment, the electromagnet 34 is powered off, the locking block 35 is separated from the adsorption state and is reinserted into the impact block 36 to re-limit the impact block 36, then the protection blanket 38 is overlapped on the side, away from the user, of the suspension limiting rod 39 again, and then the damaged stop stopper 13 is replaced.
