[0012] Furthermore, connecting springs are provided at both the front and rear ends of the left side of the movable plate, and the left side of the connecting springs is connected to the inner side of the fixed frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. When the patient sits down, the support frame can be flipped open and the affected limb placed on top of the support frame. By raising the affected limb, the swelling of the affected limb can be prevented from worsening. The mounting rod is connected to the support frame with bolts. The mounting rod can be installed in a suitable position according to the specific condition of the patient's affected limb.
[0015] Furthermore, when it is necessary to flip the mounting rod and the placement frame, the fastening bolts are separated from the threaded groove, and then the placement frame is flipped. When the affected limb needs to be placed, the placement frame is flipped to a horizontal position, so that the affected limb can be placed more comfortably. When the support frame is needed to assist walking, the placement frame is flipped to a vertical position to complete the folding and storage.
[0016] Furthermore, after the patient places the affected limb on top of the placement frame, the limb can be bound and fixed by the elastic limiting strap to prevent the limb from shifting during placement. After the angle of the placement frame is adjusted, the angle of the placement frame can be fixed by the threaded connection between the fastening bolt and the threaded groove, increasing its applicability during use.
[0017] 2. The threaded connection between the support frame and the fixed base allows for the replacement of the fixed base, enabling timely replacement after wear and tear from prolonged use, thus ensuring the safety of the walker during use. The anti-slip protrusions at the bottom of the fixed base enhance its anti-slip and wear-resistant properties, preventing slippage and increasing the walker's versatility.
[0018] Furthermore, the user needs to hold the outer side of the rubber anti-slip layer with their hand. The side of the fingers will apply a certain pressure to the moving plate, causing the moving plate to move away from the rubber anti-slip layer. The elastic airbag on the side of the moving plate is subjected to force and the gas is delivered to the inside of the inflatable soft bag, which increases the gas inside the inflatable soft bag and makes it fit better with the outside of the fingers, thereby increasing the anti-slip stability of the walker when used.

The support mechanism includes a placement frame 12, which is located on the right side of the mounting rod 11. On the side, an elastic limiting band 13 is provided on the outer side of the placement frame 12; a limiting plate 14 is provided on the side of the support frame 1, and the limiting plate 14 is located on the right side of the mounting rod 11, and a locking mechanism for fixing the limiting plate 14 is provided on the left side of the mounting rod 11; the locking mechanism includes a fastening bolt 15, and the fastening bolt 15 is threadedly connected to the outer side of the mounting rod 11, and the mounting rod 11 is provided with threaded grooves 16 in different directions, and the fastening bolt 15 is threadedly connected to the threaded grooves 16; the placement frame 12 is located on the right side of the limiting plate 14, and the length of the placement frame 12 is less than the length of one end of the support frame 1.
[0028] In this example, when using the walking aid, the patient grips the rubber anti-slip layer 4, utilizing the coordination between upper limb strength and the walking aid to assist walking, making walking more stable. For patients with unilateral fractures, when the patient sits down, the placement frame 12 can be flipped open, placing the affected limb on top of the placement frame 12. By elevating the affected limb, it prevents further swelling. The mounting rod 11 is connected to the support frame 1 by bolts, allowing the mounting rod 11 to be installed in a suitable position according to the specific condition of the patient's affected limb. After the patient places the affected limb on top of the placement frame 12, the elastic limiting strap 13 can bind and fix the affected limb, preventing... To prevent the affected limb from shifting during placement; the support frame 1 is connected to the limiting plate 14. When it is necessary to flip the mounting rod 11 and the placement frame 12, the fastening bolt 15 is separated from the threaded groove 16, and then the placement frame 12 is flipped. When the affected limb needs to be placed, the placement frame 12 is flipped to a horizontal position, so that the affected limb can be placed more comfortably. When the support frame 1 is needed to assist walking, the placement frame 12 is flipped to a vertical position and folded for storage. After the angle of the placement frame 12 is adjusted, the angle of the placement frame 12 can be fixed by the threaded connection between the fastening bolt 15 and the threaded groove 16, increasing its applicability during use.

[0032] In this example, when using the walker, the user needs to hold the outer side of the rubber anti-slip layer 4 with their hand. The side of the fingers will apply a certain pressure to the movable plate 5, causing the movable plate 5 to move away from the rubber anti-slip layer 4. The elastic airbag 8 on the side of the movable plate 5 is subjected to force and the gas is delivered to the inside of the inflatable soft bag 9, which increases the gas inside the inflatable soft bag 9 and makes it fit better with the outside of the fingers, thereby increasing the anti-slip stability of the walker when it is in use.
