[0032] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0033] Referring to Figures 1-7 , a crutch element includes an element body 10, and a first mounting hole 120 and a second mounting hole 101 are integrated on the element body 10; the lower end of the first mounting hole 120 is open for connecting a first support rod 30; the upper end of the second mounting hole 101 is open for connecting a second support rod 410. During assembly, by inserting and fixing the first support rod in the first mounting hole and the second support rod in the second mounting hole, this structure can solve the problem in the prior art that the first support rod and the second support rod need to be bolted to each other, which is not only convenient for assembly, but also the element body is integrally injection-molded, and the precision of the first mounting hole and the second mounting hole can be accurately controlled. The insertion and assembly of the mounting hole and the support rod can solve the problem of the precision of the bolt insertion and hole opening.

[0034] Referring to Figure 2 and Figure 3 , a housing 110 is provided at the upper end of the element body 10, and a hollow storage space 111 for storage is formed inside the housing 110. The provision of the storage space 111 can be used to store some daily medications and items carried with the user to enhance the user experience.

[0035] Furthermore, the housing 110 and the element body 10 are an integrated structure. The integrated structure can be formed by injection molding, and the apertures of the first mounting hole 120 and the second mounting hole can be precisely controlled by injection molding to ensure the installation stability with the first support rod 30 and the second support rod 410 .

[0036] See also Figure 3 The storage space 111 is provided with an opening on one side, and a storage box 20 is inserted into the storage space 111 on the side of the opening of the storage space 111. The storage box 20 is further provided to store items, and when taking or placing items, the storage box can be pulled out for easy taking or placing.

[0037] Furthermore, a panel 220 is provided on the outward side of the storage box 20, and a limiting groove 112 is provided at the opening of the shell 110; a positioning portion 240 is provided on the side wall of the panel 220, and a positioning groove 113 is provided in the limiting groove 112; when the panel 220 is embedded in the limiting groove 112, the positioning portion 240 can be snapped into the positioning groove 113.

[0038] The function of the panel 220 is to restrict the depth of the storage box 20 inserted into the storage space 111. At the same time, the positioning portion 240 can be inserted into the positioning groove 113 to constrain the position of the storage box 20, thereby preventing the storage box 20 from moving freely relative to the storage space 111 without the action of external force and slipping out of the storage space 111.

[0039] See also Figure 3 and Figure 4 The panel 220 is provided with a toggle block 230 for driving the storage box 20 to move outward;

[0040] The storage box 20 is provided with a notch 114 for accommodating the shifting block 230 .

[0041] The function of the toggle block 230 is to facilitate the user to press the finger on the toggle block 230 so that the user can apply a force to move the storage box 20 outward, and the setting of the groove 114 allows the toggle block 230 to be embedded therein, so that the toggle block 230 will not bulge outward, avoiding the bulge that affects the appearance or collides with the human body.

[0042] See also Figure 2 and Figure 3 The inner wall of the storage space 111 is provided with a slide groove 115, and the outer wall of the storage box 20 is provided with a slide rail 210 movably inserted into the slide groove 115. The cooperation between the slide groove 115 and the slide rail 210 can make the storage box 20 more stable during opening or closing, and enhance the stability of its movement.

[0043] See alsoFigures 1 to 3 An installation joint 100 is integrated on the housing 110, the second installation hole 101 is arranged in the installation joint 100, and the second support rod 410 can be inserted into the second installation hole 101 of the installation joint 100 from top to bottom to form an insertion assembly.

[0044] See Figures 2 to 4 A first pin hole 102 communicating with the second installation hole 101 is arranged on the installation joint 100;

[0045] A plurality of second pin holes 130 communicating with the first installation hole 120 are longitudinally arranged on the component body 10;

[0046] The component body 10, the housing 110 and the installation joint 100 are of an integral structure.

[0047] Furthermore, in the present utility model, a first elastic pin 310 is arranged on the first support rod 30, and a second elastic pin 430 is arranged on the second support rod 410.

[0048] When the first support rod 30 is inserted and assembled with the first installation hole 120, the first elastic pin 310 can be inserted into any one of the second pin holes 130. This connection can restrict the up and down position of the first support rod 30 relative to the component body 10. According to the first elastic pin 310 being inserted into different second pin holes 130, the up and down position of the first support rod 30 can be adjusted to realize the height support adjustment of the walking stick.

[0049] When the second support rod 410 is inserted and assembled with the second installation hole 102, the second elastic pin 430 is inserted into the first pin hole 102, and this connection can restrict the up and down position of the second support rod 410 relative to the component body 10.

[0050] Furthermore, a plurality of clamping pieces 103 that can be attached to the outer wall of the second support rod 410 are arranged on the installation joint 100 in a circumferential arrangement. A threaded locking sleeve 50 threadedly connected to the plurality of clamping pieces 103 is sleeved on the second support rod 410. A conical surface 510 is arranged on the inner wall of the threaded locking sleeve 50, and an inclined surface 104 matching with the conical surface 510 is arranged on the upper part of the clamping piece 103. When the threaded locking sleeve 50 is gradually screwed down, the conical surface 510 and the inclined surface 104 squeeze the clamping piece 103 inward, so that the clamping piece 103 clamps the second support rod 410 inward.

[0051] See Figures 4 to 7 A walking stick, comprising a first support rod 30 and a support assembly 40, further comprising a component body 10, and a first installation hole 120 and a second installation hole 101 are integrated on the component body 10;

[0052] The first support rod 30 is detachably installed in the first mounting hole 120;

[0053] The support assembly 40 includes a second support rod 410, and a hand support element 440 and an axillary support element 420 are arranged on the second support rod 410;

[0054] The lower end of the second support rod 410 is detachably installed in the second mounting hole 101.

[0055] Furthermore, there are two second support rods 410 which are arranged at intervals left and right. The left and right ends of the hand support element 440 and the left and right ends of the axillary support element 420 are both connected to the two second support rods 410 on the left and right. In this embodiment, the second mounting hole 101 is arranged corresponding to the number of the second support rods 410.
