Description

technical field [0001] The invention relates to the technical field of crutches, in particular to a folding crutch. Background technique [0002] Known crutches generally have different types such as hand canes that can be held by hands, forearm crutches or underarm crutches that can support armpits, such as Figure 13 Shown is one of the known underarm crutch structures, which has a support rod 1', a connecting frame 2', a cushion 3', and a handle 4'. A soft cover that can touch the ground is arranged under the support rod 1'. Body 11', and the connecting frame 2' has two rods 21', the lower part of the two rods 21' is fixedly connected to the support rod 1', the upper part is connected to the cushion 3', and the center is connected to the handle 4', so that the user's armpit is placed on the backrest 3 When the palm of the hand can hold the handle 4', the sleeve body 11' below the support rod 1' can touch the ground to form a support point. [0003] However, the aforement...

AI Technical Summary

Problems solved by technology

[0004] 1. The armpit crutches must have a relatively long length from the armpit to the ground. It is inconvenient to store and store when not in use, and it is not easy to carry in the car

[0005] 2. The soft sleeve 11' under the support rod 1' has poor shock absorption effect, which makes walking with the crutch uncomfortable and lacking

[0006] 3. The combined height of back cushion 3' and handle 4' is not easy to adjust and cannot be used by different users

[0008] In order to improve the above-mentioned deficiency, such as the crutches of Taiwan TWM266902, detachable upper and lower lever sets are designed. The upper and lower lever sets are respectively provided with a jacket and an insertion rod, and a ring that can be rotated to tighten the jacket, so that the insertion rod can be detached. The jacket allows the upper and lower rods to be separated and folded, and the insertion rod can be inserted into the jacket and then tightened to tighten the buckle so that the upper and lower rods can be combined stably. However, this combinat
