[0030] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing mechanism 4 includes a shell 41 fixedly connected to the upper surface of the frame 1, the inner surface of the shell 41 is rotatably connected to a worm 42, one end of the worm 42 is fixedly connected to a handwheel 43, the outer surface of the worm 42 is meshingly connected to a worm wheel 44, the inner surface of the worm wheel 44 is fixedly connected to a rotating rod 45, the outer surface of the rotating rod 45 is symmetrically rotatably connected to two fixed blocks 46, the two fixed blocks 46 are fixedly connected to one of the frames 1, the outer surface of the rotating rod 45 located between the fixed blocks 46 is fixedly connected to a connecting plate 47, a fixing plate 48 is provided on one side of the connecting plate 47, and the fixing plate 48 is fixedly connected to the connecting plate 47 via an adjusting mechanism 49.

[0031] When in use, the hand wheel 43 is turned, and the worm 42 is driven to rotate by the hand wheel 43, and the worm gear 44 is driven to rotate by the worm 42, and then the rotating rod 45 is driven to rotate, and then the connecting plate 47 and the fixing plate 48 are driven to rotate to a suitable position by the rotating rod 45, and the fixed state of the folded frame 1 is released, and the frame 1 can be unfolded for use. After use, the frame 1 is folded, and then the hand wheel 43 is reversed, and the worm 42 is reversed by the hand wheel 43, and the worm gear 44 is reversed by the worm 42, and then the rotating rod 45 is reversed, and then the connecting plate 47 and the fixing plate 48 are reversed and restored to their original positions by the rotating rod 45. At this time, the fixing plate 48 contacts the farthest frame 1 to fix the folded frame 1, and then the device can be placed in a carriage for transportation;

[0032] The function of quickly fixing and releasing the fixed state of the frame 1 after folding is realized. Through the cooperation of the shell 41, the worm 42, the hand wheel 43, the worm gear 44, the rotating rod 45, the fixing block 46, the connecting plate 47 and the fixing plate 48, the folded frame 1 can be quickly fixed and released from the fixed state, which saves time and labor, and facilitates the folding, fixing and use of the frame 1.

[0033] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the adjustment mechanism 49 includes a threaded rod 491 fixedly connected to the surface of one side of the connecting plate 47, the outer surface of the threaded rod 491 is threadedly connected with a sleeve 492, the sleeve 492 is rotatably connected to the fixed plate 48, one end of the sleeve 492 is fixedly connected to a rotating block 493, and one side surface of the fixed plate 48 is symmetrically fixedly connected with two limit rods 494, and the two limit rods 494 are both slidably connected to the connecting plate 47.

[0034] When in use, according to the actual number of the frame 1, the rotating block 493 is rotated, and the sleeve 492 is driven to rotate by the rotating block 493. Since the sleeve 492 is threadedly connected with the threaded rod 491, the sleeve 492 moves when it rotates, and then the fixed plate 48 is driven to move to a suitable position by the movement of the sleeve 492. In this process, the fixed plate 48 moves stably through the limiting rod 494;

[0035] The function of adjusting the position of the fixing plate 48 is realized. Through the cooperation of the threaded rod 491, the sleeve 492, the rotating block 493 and the limiting rod 494, when the number of folding frames 1 increases, the position of the fixing plate 48 can be adjusted to meet the fixing requirements of different numbers of folding frames 1, thereby improving the adaptability of the device.

[0036] Specifically, Figure 1 , Figure 2 and Figure 3As shown, the outer surface of the rotating block 493 is provided with anti-slip grooves to increase the contact friction with the fingers, thereby facilitating the rotation of the rotating block 493.

[0037] Specifically, Figure 2 and Figure 3 As shown, a protective shell 11 is fixedly connected to a surface of one side of the connecting plate 47 located outside the threaded rod 491 , and the protective shell 11 is slidably connected to the sleeve 492 , and the threaded rod 491 is protected by the protective shell 11 .

[0039] Working principle: when in use, turn the hand wheel 43, and the worm 42 is driven to rotate by the hand wheel 43, and the worm wheel 44 is driven to rotate by the worm 42, and then the rotating rod 45 is driven to rotate, and then the connecting plate 47 and the fixing plate 48 are driven to rotate to a suitable position by the rotating rod 45, and the fixed state of the folded frame 1 is released, and the frame 1 can be unfolded for use. After use, the frame 1 is folded, and then the hand wheel 43 is reversed, and the worm 42 is reversed by the reversal of the hand wheel 43, and then the worm wheel 44 is reversed by the reversal of the worm 42, and then the rotating rod 45 is reversed, and then the connecting plate 47 and the fixing plate 48 are reversed and restored to their original positions by the reversal of the rotating rod 45. At this time, the fixing plate 48 contacts the farthest frame 1, fixes the folded frame 1, and then the device can be placed in the carriage for transportation;

[0040] When the number of folded frames 1 increases, the rotating block 493 is rotated, and the sleeve 492 is driven to rotate by the rotating block 493. Since the sleeve 492 is threadedly connected to the threaded rod 491, the sleeve 492 moves when it rotates, and then the fixed plate 48 is driven to move to the appropriate position by the movement of the sleeve 492. In this process, the movement of the fixed plate 48 is stable through the limit rod 494.
