The working principle and the using process of the invention are as follows: firstly, the limiting plate 602 is placed in the limiting groove 601, and then the limiting frame 605 is clamped in the limiting groove 601 through the clamping hole 604, so that the limiting plate 602 is limited, and when the connecting band 204 is pulled, the limiting rotating shaft 603 extrudes the connecting band 204, so that the phenomenon that the connecting band 204 is twisted in the pulling process is avoided, and the connecting band 204 is damaged;

the sleeve 401 is sleeved on the waist of an exerciser, the lantern ring 408 is slowly pulled by both hands, the embedded belt 407 drives the bandage 404 to slide in the sliding groove 403, the bandage 404 is conveniently and quickly pulled due to the action of the rolling shaft 406, so that the sleeve 401 is contracted, and then the lantern ring 408 is sleeved inside the hooks 409 at different positions, so that the bandage 404 is conveniently fixed, and the sleeve 401 is fixed on the waist of the exerciser;

second, a taller exerciser may train directly on the placement board 302, a shorter exerciser may place the board 302 on a stand and then step the pedals 308 down with their feet, thereby causing the pedal 308 to move the pressure plate 307, causing the pressure plate 307 to move at the outer end of the fixing rod 306, when the pressing plate 307 contacts the baffle plate 310, the baffle plate 310 is driven to separate from the placing plate 302, and then the baffle plate 310 is snapped inside the receiving hole 309, so that the limitation of the placing plate 302 is released, meanwhile, one end of the pressing plate 307 contacts the inner wall of the guide block 312, which drives the guide block 312 to rotate at one end of the fastening bolt 311, when the guide block 312 is perpendicular to the fastening bolt 311, the guide block 312 is made to restrict the outer end of the step 308, therefore, when a person with a short person falls down after doing exercise, due to the height of the extension spring 301, the impact force of the exerciser when falling is buffered, so that the leg muscles of the exerciser are protected;

then, when the exerciser trains, the sleeve 401 drives the connecting band 204 to move, so that the connecting band 204 drives the rotating rod 206 to rotate, thereby the connecting band 204 drives the connecting block 203 to slide at the outer end of the guide rod 202, when the exerciser is a beginner, the clamping plate 211 is clamped inside the clamping groove 210, thereby the auxiliary exerciser is convenient to pull upwards through the cooperation of the embedded plate 213 and the extension spring 212, the muscle is prevented from being pulled upwards forcibly, the support rod 215 is sleeved inside the embedded groove 214 when the exerciser does not need to be assisted, thereby the installation of the bearing frame 216 is completed, the bearing weight is put into the bearing frame 216, so that the exerciser can add proper weight according to the self condition, and the exercise effect is improved;

then, the holding rod 502 is held by the hand of the exerciser, the air bag 506 is pinched by the other hand, and then force is applied, so that the magnesium powder in the connecting pipe 505 is blown out of the conveying hole 507 through the storage chamber 504 by the air flow generated by the air bag 506, and therefore the palm of the exerciser is conveniently stained with the magnesium powder, and the phenomenon that the palm of the exerciser falls down and is injured due to sweating at a long-time exercise position is avoided;

then, after the exercise, when needing to carry out the inspection and maintenance to connecting band 204, will restrict frame 605 and take out from joint hole 604 is inside, thereby relieve the spacing of restriction board 602, make things convenient for the staff to take out restriction board 602 from limiting groove 601 is inside, so that the condition of connecting band 204 is convenient for observe, in addition, rotate holding rod 502, make holding rod 502 pass through thread groove 501 and support frame 1 separation, pull holding rod 502 afterwards, make because the effect of accomodating groove 508, shrink, so that dismantle holding rod 502, conveniently wash and pour into the magnesium powder into to connecting pipe 505 inside again.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
