The main pole 1 extends up and down on a ground and includes a main erecting portion 11 at the bottom end and contacting the ground, a mounting portion 12 extending upward from the main struts 11 , and a mounting portion The extending portion 13 of the portion 12 extends upward, and a grip portion 14 that is curved by the extending portion 13 to one side. The main struts 11 can be made of a material having a retardation such as rubber to avoid slippage with the ground. The mounting portion 12 has two mounting grooves 121 that are spaced apart from each other on the left and right sides and that are recessed upward and downward, and two support shafts 122 that are respectively mounted in the mounting grooves 121. Each of the support shafts 122 extends laterally across the opposite inner side walls of the respective mounting slots 121. The extension of the extension portion 13 can be designed to match the height of the user. In the embodiment, the extension portion 13 is designed to have a fixed length, but the implementation can also be designed to have a variable length for the user to adjust and use. The grip portion 14 has an inverted U shape for easy access and hooking, but may be other curved shapes or upright extensions, which is not limited to the embodiment.

The stand 2 includes two legs 20 that are pivotally pivotally coupled to the mounting portion 12, respectively. Each of the legs 20 has a straight rod shape and can be inserted into each of the mounting slots 121, and has a separate support shaft 122 for allowing the legs 20 to pivotally pivotally connect to the mounting portion 12. The pivoting portion 21, a pressure receiving portion 22 located above the pivoting portion 21, and an auxiliary supporting portion 23 at the bottom end.

Referring to Figures 2, 3 and 4, the stand 2 can be pushed and pulled by a user with respect to the main bar 1 in a folded position as shown in Figure 2, and a Move between the deployed positions as shown in Figure 4. When the stand 2 is in the folded position, the auxiliary support portion 23 of each leg 20 is located in the mounting groove 121, so that the legs 20 are completely loaded into the mounting slots 121, and The mounting portion 12 cooperates to present a complete cylinder to achieve the advantages of being neat and tidy, and does not occupy space when walking or carrying, and when the user walks with the present invention, the main support is retarded. The stand 11 can also avoid slipping when standing on the ground. It should be noted that, in this embodiment, each of the legs 20 is pivotally disposed on the respective support shafts 122, so that the legs 20 cannot pivot independently on the support shafts 122, respectively. The user can push and pull the legs 20 with a little force, so when the stand 2 is in the folded position, each leg 20 will not be different because the user shakes the new type. The slot 121 is mounted.

Referring to FIG. 3, FIG. 4 and FIG. 5, when the user is finished, the user can pull the auxiliary supporting portion 23 of the leg 20 located in the mounting groove 121 to the imaginary line position as shown in FIG. The leg 20 is at an angle θ with the main rod 1 and the pressure receiving portion 22 of the leg 20 abuts against the inner wall of the mounting groove 121, and two recesses are respectively disposed on the bottom sides of each of the mounting slots 121. A groove (not shown) is provided for the user to grasp and pull the auxiliary support portion 23 with a thumb. Then, the user pulls out another leg 20 in the above manner, and swings the stand 2 to the deployed position. At this time, the main support 11 and the auxiliary support 23 can be not in line. The ground support is supported on the ground. In this embodiment, the main support portion 11 is used as a top angle and cooperates with the auxiliary support portions 23 to present an isosceles triangle as shown in FIG. 5, but the implementation is not limit. In this way, the present invention can be placed directly on the ground To facilitate the next take. It should be noted that the angle θ of each leg 20 and the main rod 1 cannot be too large, and must be matched with the position of the center of gravity of the main rod 1. In the embodiment, the angle θ is 15°-20°. If the angle is too large, the position of the center of gravity of the crutches will be excessively offset and cause dumping. If the angle is too small, the center of gravity of the crutches will be unstable and easy to dump, but the implementation is not limited thereto.

In summary, the new cane can be used to take the tripod 2 to the folding position during use, so as to facilitate walking and carrying without taking up space, the legs 20 can be pulled out after use. The tripod 2 is deployed to the deployed position, so that the present invention can be directly placed on the ground for convenient access, so that the purpose of the present invention can be achieved.

Referring to FIG. 6 and FIG. 7, a second embodiment of the walking stick with a folding stand according to the present invention is different from the first embodiment in that the walking stick further comprises a main rod 1 disposed thereon and constantly generating one The tripod 2 returns to the elastic biasing force resetting unit 3 of the deployed position, and a sliding sleeve 4 slidable along the main rod 1. The resetting unit 3 includes two torsion springs 31, each of which is mounted between the respective leg 20 and the inner wall of the corresponding mounting groove 121, and has a supporting end that connects the inner wall of the mounting groove 121. 32, and a force applying end 33 that connects the leg 20 and is displaceable as the leg 20 swings. The mounting portion 12 further has a sliding slot 123 extending upwardly and upwardly. The sliding sleeve 4 is sleeve-shaped and includes a slider 41 corresponding to the sliding slot 123. The sliding slot 123 and the slider 41 cooperate with each other. The sliding sleeve 4 can be restrained from sliding between the extending portion 13 and the mounting portion 12.

When in use, the sliding sleeve 4 can be slid downward from the extension portion 13 And pressing the legs 20 to the outside of the legs 20, respectively, and pressing the legs 20 into the mounting slots 121, respectively, until the sliding sleeve 4 moves to the mounting portion 12, the legs 20 will The biasing end 33 of the torsion springs 31 is biased inwardly, so that the torsion springs 31 accumulate the elastic restoring force, and the tripod 2 is received in the folded position. When the use is completed, the sliding sleeve 4 can be slid upward to the extending portion 13. At this time, the torsion springs 31 respectively release the accumulated elastic restoring force, and the legs 20 are respectively turned by the force applying ends 33.
