that the second rotating block 801 rotates, the locking post 803 on the upper surface of the second rotating block 801 can be pushed, the locking post 803 is pushed into the through hole 804 formed on the upper surface of the limiting disc 806, the second rotating block 801 is fixed, and then the butt plate 701 and the clamping groove 807 are mutually attached, the second rotating block 801 is fixed secondarily, the clamping block 810 fixedly mounted at one end of the second rotating block 801 can be clamped in the clamping groove 807 formed in one end of the limiting disc 806, so that the second rotating block 801 can slide in the sliding cylinder 809 formed in the upper surface of the limiting disc 806, the clamping block 810 fixedly mounted on the lower surface of the second rotating block 801 can slide out of the clamping groove 807, the second rotating block 801 can be rotated, the inclination of the horizontal bar arm 9 can be adjusted through the adjusting component 4 when the single and double bars are unfolded, the adjusting component 4 can also be used for folding and storing the horizontal bar arm 9, when the single and double bars are folded integrally, the two groups of balance plates 1 and the supporting frame 3 are close to the center through the folding component 7, the locking component 6 needs to be detached from the folding component 7 and placed in the placing plate 2, the horizontal bar is convenient to store after folding, the occupied space is reduced, the horizontal bar is locked through the locking component 6, the horizontal bar is prevented from being folded, and the locking component 6 is prevented from being folded, and the locking component is prevented from being folded.

To sum up: this double-deck locking protection folding parallel bars, through the cooperation between adjusting part 4, locking part 6, folding part 7 and the control assembly 8, the parallel bars has been solved when not using, can occupy a large amount of occupation of land spaces, and inconvenient depositing, can not accomodate its quick folding operation, need store the connection when storing the parallel bars, store the part, just can accomodate it, waste time and energy, when using, still need assemble, and can appear fixed unstable condition because fixed insecure during the in-process of equipment, appear not hard up between just the parallel bars part, can not carry out the problem of quick fixation to it.
