then, each support frame 300 is mounted on the connecting rod 200; inverting the fabric sheet, aligning the left clamping part 7 with the left connecting rod 200, and clamping the left connecting rod 200 into the left clamping part 7; then, the right-side clamping portion 7 is installed, the cap 821 is pressed inwards, the cap 821 pushes the middle sliding column 822 to move inwards, the middle sliding column 822 pushes the second head portion 141 of the second elastic pin 14 to move inwards, the second head portion 141 of the second elastic pin 14 is far away from the sixth through hole 831 of the fixing sleeve 83, the locking mechanism 8 is unlocked, the handle 81 is rotated (at this time, the second elastic pin 14 is not limited by the handle 81 and returns to the state of extending outwards out of the right ejector rod 12), and the movable clamping portion 71 and the fixed clamping portion 72 are far away from each other; abutting the movable half-clamping portion 71 against the right connecting rod 200 (see fig. 11, 12); then the handle 81 is rotated, in the rotating process of the handle 81, the guiding portion 812 (see fig. 11 and 12) on the inner wall of the handle 81 can abut against the second head portion 141 of the second elastic pin 14, the handle 81 continues to rotate, so that after the second head portion 141 of the second elastic pin 14 retreats inwards into the right top rod 12, the second head portion 141 of the second elastic pin 14 springs outwards again to extend into the sixth through hole 831 of the fixing sleeve 83, the locking mechanism 8 is locked, in the process, the movable clamping portion 71 pulls the corresponding connecting rod 200 to move outwards, so that the fabric piece connected to the connecting rod 200 is unfolded, and thus the step of mounting the clamping portion 7 on the right side on the connecting rod 200 on the right side is completed; at this time, the left clamping portion 7 plays a role of supporting and clamping the left connecting rod 200, the right fixed clamping portion 72 plays a role of supporting the right connecting rod 200, and the right movable clamping portion 71 plays a role of clamping the right connecting rod 200;

then the supporting frame 300 and the fabric piece are turned over to be in a use state;

when the camp bed needs to be stored, the button 82 of the locking mechanism 8 is acted inwards to release the locking of the locking mechanism 8, so that the movable clamping part 72 on the right side is separated from the connecting rod 200 on the right side, then the clamping part 7 on the left side is separated from the connecting rod 200 on the left side, and the seat body 70 of each support frame 300 is pulled outwards (see fig. 10), so that the corresponding seat body 70 and the corresponding ejector rod 1 can be bent towards the middle of the cross rod 2 under the action of the first elastic rope 5; the two adjacent connecting sections 201 are separated (see fig. 17), and under the action of the second elastic rope 203, each connecting rod 200 can be bent; and (5) stacking the fabric pieces in order.

Referring to fig. 18-19, a frame of a camp bed is shown at a second height;

when the camp bed is required to be used in a state where the frame has the second height,

after the bed frame is in the first height state, the elastic pins 40 are removed from the pin insertion holes 30 after the flange 403 is pressed inward, and the pins 3 are inserted into the pin insertion holes 30 to act on the pins 3 upward, so that the first heads 321 of the first elastic pins 32 can extend outward from the first through holes 50 of the seat body 70, and the position of the pins 3 is fixed; similarly, the second height specification of the support frame 300 can be obtained by installing other foot rods 3;

when the camp bed needs to be stored, all the foot rods 3 are detached; similarly, the button 82 of the locking mechanism 8 is acted inward to release the locking of the locking mechanism 8, so that the movable clamping portion 72 on the right side is separated from the connecting rod 200 on the right side, the clamping portion 7 on the left side is separated from the connecting rod 200 on the left side, and the seat body 70 of each support frame 300 is pulled outward (see fig. 10), so that the corresponding seat body 70 and the corresponding top rod 1 can be bent toward the middle of the cross rod 2 under the action of the first elastic rope 5; the two adjacent connecting sections 201 are separated (see fig. 17), and each connecting rod 200 can be bent under the action of the second elastic rope 203; the fabric pieces are stacked in order; and (4) finishing.
