Furthermore, a first sliding bar 11 is arranged in the first sleeve 7 along the length direction, a first sliding groove 12 is arranged on the first sliding bar 8 along the length direction, the first sliding bar 11 is located in the first sliding groove 12, the first sliding bar 8 can rotate in the first sleeve 7, the width of the first sliding groove 12 is larger than that of the first sliding bar 11, and therefore the first sliding bar 8 can rotate in the first sliding sleeve 7.

Furthermore, the rotation angle of the first sliding rod 8 is 0-15 degrees, so that the exercise habit of non-professional exercisers is better met, and the exercise effect is enhanced.

Further, splint 5's side still is equipped with fixture block and draw-in groove, and the fixture block on one of them splint corresponds to the draw-in groove on another splint, and when two splint 5 closed up, in the fixture block on one of them splint can insert the draw-in groove on another splint, can make two splint 5 synchronous rotations, prevents the dislocation, influences body-building experience.

Further, the support rod 3 comprises a sliding part 13 and a support part 14, the sliding part 13 is connected with the armrest 2 in a sliding manner, and the support part 14 is connected with the sliding sleeve 6 in a sliding manner.

Furthermore, a through hole 15 is vertically formed in the armrest 2, the sliding portion 13 is slidably disposed in the through hole 15, a second sliding groove 16 is formed in the through hole 15, a second sliding strip 17 matched with the second sliding groove 16 is disposed on the sliding portion 13 along the length direction, and the second sliding strip 17 is slidably disposed in the second sliding groove 16 to prevent the support rod 3 from rotating in the through hole 15.

Furthermore, a first fixing hole 18 is further formed on the armrest 2, the first fixing hole 18 is perpendicular to the through hole 15, the first fixing holes 18 are communicated with the through holes 15, a plurality of second fixing holes 19 matched with the first fixing holes 18 are uniformly arranged on the second slide bar 17 along the length direction, a fixing rod 20 is arranged in the first fixing hole 18 in a sliding manner, one end of the fixing rod 20 is inserted into one of the second fixing holes 19, the height of the protective device can be adjusted, when the fixed rod 20 is pulled, the fixed rod 20 is separated from the second fixed hole 19, the supporting rod 3 can slide up and down in the through hole 15 to adjust the height, after the adjustment is finished, the fixed rod 20 is loosened, the fixing rod 20 is reset by the reset spring and is inserted into the second fixing hole 19, so as to complete the locking and fixing of the support rod 3.

Furthermore, a stop block 21 is arranged at one end of the fixing rod 20 far away from the support rod 3, a return spring 22 is sleeved on the fixing rod 20, one end of the return spring 22 is fixedly connected with the stop block 21, and the other end of the return spring is fixedly connected with the handrail 2.

Further, a second stop ring 23 is arranged between the sliding portion 13 and the supporting portion 14, a buffer spring 24 is sleeved on the supporting portion 14, one end of the buffer spring 24 is fixedly connected with the second stop ring 23, and the other end of the buffer spring is fixedly connected with the sliding sleeve 6.

Further, be equipped with third spout 25 along length direction on the supporting part 14, be equipped with third draw runner 26 on the sliding sleeve 6, third draw runner 26 slides and sets up in third spout 25, because protection device mainly plays the guard action, so if bracing piece 3 rotates in through-hole 15 or sliding sleeve 6 rotates on supporting part 14, two splint 5 just can separate, can't play the effect of protection.

Further, the inboard of splint 5 is equipped with a plurality of buffering gasbags 27, and buffering gasbag 27 can play the effect of buffering, because splint 5 need adopt hard material to make just can play the guard action, so lie in that the comfortable sensation of human contact in-process can reduce to some extent, set up buffering gasbag 27 and can improve the comfort, still can avoid colliding with.

Further, the running device comprises a fixed plate 28, a running plate 29 and a track 30, wherein the fixed plate 28 is fixedly connected with the chassis 1, the running plate 29 is positioned above the fixed plate 28, a plurality of damping springs 31 are arranged between the fixed plate 28 and the running plate 29, and both the fixed plate 28 and the running plate 29 are covered by the track 30. The person of taking exercise runs on track 30, and fixed plate 28 plays the effect of support with chassis 1 fixed connection, runs board 29 and sets up the effect that plays support on fixed plate 28, and damping spring 31 can play the absorbing effect of buffering at the running in-process, avoids taking exercise personnel joint damage.

Further, still be equipped with shock attenuation sponge 32 between fixed plate 28 and the running board 29, shock attenuation sponge 32 can play the absorbing effect of buffering equally, can also play the effect of inhaling the sound simultaneously, can effectively reduce the noise that produces at the running in-process.

The using method comprises the following steps: the exerciser firstly adjusts the height of the supporting rod 3 according to the height of the exerciser, the fixing rod 20 is pulled outwards to separate the fixing rod 20 from the second fixing hole 19, then the supporting rod 3 is slid up and down to a proper position, after the fixing rod 20 is loosened, the fixing rod is reinserted into the second fixing hole due to the elasticity of the return spring 22 to complete the height adjustment, then the two clamping plates 5 are pushed towards two sides to separate the two clamping plates 5, the exerciser enters from the gap between the two clamping plates 5, then the two clamping plates 5 are closed by the pushing force of the clamping spring 10, the exerciser is positioned between the two clamping plates 5, then the treadmill is started, the exerciser exercises on the treadmill, the exerciser can fluctuate up and down during running, and the buffer spring 24 is arranged on the supporting part 14, so the clamping plates 5 are connected with the sliding sleeve 6 through the connecting rod 4, and the sliding sleeve 6 can slide up and down on the supporting part 14, thereby being more fit with the exerciser; the personnel of taking exercise can incline forward at the general meeting of running in-process health, first slide bar 8 can be at the internal rotation of first sliding sleeve 7, consequently splint 5 also can produce the rotation of certain range, because the ordinary personnel angle of anteversion is generally within 15 degrees in the exercise process, consequently first slide bar 8's angle of rotation is also within 15 degrees, can laminate more with the personnel of taking exercise, consequently, can make the exercise effect better, simultaneously can also play the guard action in the motion process, avoid the personnel of taking exercise to fall down on the treadmill because of the uncomfortable or break away from to lead to.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
