In addition, in other embodiments, the handle may only include a handle that is swingably disposed at the first end of the body, and the user swings the handle to a predetermined angle (eg, relative to the body) 90° or other angles), the handle can also be used for the user to ride, or with a support structure, the support structure can be abutted against the handle when the handle swings to a preset angle Between the main bodies, the handle is firmly placed in a horizontal position for the user to ride.

The frame body 3 includes a plurality of brackets 31 (in this embodiment, three brackets are provided), and the brackets 31 are swingably disposed at the second end of the body 1 , and the brackets 31 are selectively unfolded or relatively folded; Each bracket is provided with a card slot for pushing against the top member 13 so that when the brackets 31 are relatively unfolded (as shown in FIGS. 3 and 6 ), the abutting member 13 can be used to abut the card slot of the bracket 31 . The bracket 31 is positioned, and then the handle 21 is relatively unfolded, so that the present invention can be turned into a seat (as shown in FIG. 4); and after the brackets 31 are relatively folded, the handles 21 are folded again. You can The invention is turned into a cane (as shown in FIG. 2); and when the brackets 31 are relatively folded, the sleeve 12 adjacent to the second end of the main body 1 can be nested into one end of the brackets 31 (as shown in FIG. 2). In order to limit the brackets 31 from being unfolded relative to each other; each of the brackets 31 has a hollow tubular structure and a first through hole 311 and a second through hole 312 are disposed adjacent to the end.

Referring to FIG. 1 , FIG. 5 and FIG. 6 , the limiting mechanism 4 includes a plurality of wire take-up devices and a plurality of wires 42 (the wires are in the present embodiment, and may be replaced with other wires or wires of different materials or types). The wire-receiving device is disposed in each of the brackets 31, and includes a wire-receiving body 411, an elastic member 412 and a fixing portion 413. Each of the wire-receiving bodies 411 is slidably disposed on each of the brackets 31, and each of the elastic members The 412 is disposed on each of the brackets 31 and the wire receiving body 411 is connected to one end of the elastic member 412. Each of the fixing portions 413 is fixed to each of the brackets 31. Each of the elastic members 412 is disposed on each of the fixing portions 413 and each of the fixing portions 413. Between the retracting bodies 411, and the fixing portion 413 is located on one side of the end of the bracket 31 (as shown in FIG. 5), and is fixed by the elastic member 412 against the fixing portion 413 and the retracting body 411. Both the portion 413 and the wire take-up body 411 can be separated from each other without applying an external force; one end of each of the wires 42 is provided on each of the brackets 31 and connected to the wire take-up body 411 of the bracket 31, more specifically The end is inserted through the second through hole 312 of the bracket 31 and sequentially passes through the fixing portion 413, the bullet The body 412 and the wire take-up body 411; the other end of the wire 42 is disposed on another adjacent bracket, and the end is disposed through each of the first through holes 311 and formed with a larger outer diameter stop portion 421, the wire 42 The bracket 31 is locked by the stopping portion 421; the wire 42 can limit the The angle of deployment of the brackets 31, more specifically, when the two brackets 31 to which the wires 42 are attached are deployed in a relatively far direction, since the wires 42 are stretched, the stoppers 421 at one end of the wires 42 are blocked in one of them. The other end of the bracket drives the connected wire take-up main body 411 to move toward the fixing portion 413 (as shown in FIG. 5 to FIG. 6), so that the wire take-up main body 411 compresses the elastic member 412, and is restricted by the fixing portion 413. The wire 42 can be blocked, so that the deployment angle of each bracket 31 is restricted by the tension of the wire 42. For the same reason, as long as the brackets 31 are folded together, the elastic body 412 elastically drives the wire to take over the body. The 411 will drive the wire 42 to be automatically received into the bracket 31 so that the user can quickly fold the brackets together. Therefore, the two ends of the wire 42 are respectively disposed on the two brackets 31, and the two brackets 31 are connected to the two wires 42. In this embodiment, three wires 42 are provided to correspond to the three brackets 31, so that the wires are respectively Each bracket is surrounded, of course, the number of wires can also be increased or decreased, as long as the wire is disposed at least in the two brackets and one end is connected with the wire take-up body, such as a single wire to pass through the brackets, or each bracket Form a limit effect. In addition, the fixing portion and the wire take-up body may be reversed, so that the elastic member may be stretched and deformed when the bracket is in the unfolded state, or the wire take-up device may be used as a cord reel structure in other embodiments. It is also impossible to use the spring to roll the wire into the bracket.

Thereby, when the user wants to change the invention into a chair ride, the brackets 31 can be directly unfolded to abut against the ground (as shown in FIG. 3), and the grips 2 are further unfolded to form a seat portion. (as shown in Figure 4), that can be used as a chair use. When the brackets are deployed, the deployment angles of the brackets 31 are restricted by the respective wires 42 so that the brackets 31 cannot be fully deployed, and when the brackets 31 are moved in the relative deployment direction, the wires 42 are unfolded by the brackets 31. And stretching, thereby driving the wire take-up body 411 to which it is connected, moving the wire take-up body 411 toward each of the fixing portions 413 to press the elastic member 412, and allowing more wires 42 to protrude out of the bracket, waiting for the wire When the stretching length of 42 reaches the limit, each bracket 31 is restrained by the wire 42 and maintained at a predetermined deployment angle (as shown in FIGS. 4 and 6); and although the elastic member 412 is compressed, by the user The weight is pressed to keep the brackets 31 in a relatively unfolded state for the user to ride smoothly; and when the user folds the brackets after use, the compression elastic force of the elastic members 412 can drive the collection. The wire body 411 allows the wire 42 to be automatically received into the bracket as the bracket is folded (the force of the wire meshing can be designed according to the elastic force of the elastic member), and the user only needs to fold the handle again. , you can change back to the account structure (as shown 2)).

Therefore, the present invention allows the user to easily change the use of the chair or the cane, and simply swings the folding handle and the bracket; and, in addition, the effect of the elastic member on the wire is achieved while the brackets are folded. The wire will also be recycled to the bracket in synchronization, so that the user can quickly carry out the cooperation of the bracket, which is quite convenient, and the wire is not directly exposed and hung on the outside, so as to have both external appearance and ease of use; The conventional structure needs to have a complicated structural difference in that the structure of the invention is more compact and convenient to use, and the wire design can greatly reduce the overall weight, so as to improve the convenience of carrying and using, and further, the components are placed in the bracket, so will not have The use of accidental contact or collision damage occurs to achieve both stability of use and external beauty.
