When an element is referred to as being "connected" to another element, it can be directly connected to the other element or can have a middle element.

[0040] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description and cannot be understood as indicating or implying the relative importance of the technical features or implying the number of the technical features indicated. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor in the protection scope required by the present application.

[0041] Please refer to Figures 1 to 9 The utility model provides a four corner crutch, including handle 1, main rod 2, main frame 3 and foot pipe 4. Among them, main rod 2 is detachably connected with handle 1. Main frame 3 is sleeved on main rod 2, and main frame 3 has four sleeve pipes 31, and main frame 3 is detachably connected with main rod 2 through first bolt 5. Foot pipe 4 is provided with four, namely four supporting parts of four corner crutch, four foot pipes 4 are respectively inserted in four sleeve pipes 31, and foot pipe 4 is detachably connected with sleeve pipe 31 through second bolt.

[0042] It can be seen that the utility model discloses four corner crutch is split into handle 1, main rod 2, main frame 3 and foot pipe 4 etc. parts, and main frame 3 is connected with main rod 2 with the help of first bolt 5 and main frame 3 is connected with foot pipe 4 with the help of second bolt, so that the disassembly of main frame 3 and main rod 2 and the disassembly of main frame 3 and foot pipe 4 are more convenient, when first bolt 5 and second bolt are removed, main frame 3 can be separated from main rod 2 and sleeve pipe 31 on main frame 3 can be separated from foot pipe 4, so that four corner crutch parts can be split and stored in the place with small space, which is convenient to carry.

[0043] As Figures 1 to 6 It is shown that optionally, a plurality of height adjusting holes 201 are distributed on main rod 2 along the height direction of main rod 2, and first insertion hole 301 is arranged on main frame 3 and matched with height adjusting hole 201, so that when main frame 3 is connected with foot pipe 4, the height of handle 1 of four corner crutch can be adjusted.

[0044] It can be understood that in order to make main frame 3 and main rod 2 can be connected through first bolt 5, height adjusting hole 201 should be relatively provided with at least two rows, and first insertion hole 301 should be relatively provided with at least two, so that first bolt 5 can penetrate main frame 3 and main rod 2 at the same time, so that first bolt 5 plays the role of connecting main frame 3 and main rod 2.

[0045] As Figure 8 And Figure 9As shown, optionally, the sleeve 31 is provided with a second insertion hole 311 for the second insertion pin to pass through, and the foot pipe 4 is provided with a third insertion hole 401 for the second insertion pin to pass through. The second insertion hole 311 should be oppositely provided with at least two, and similarly, the third insertion hole 401 should be oppositely provided with at least two. Thus, when the second insertion pin passes through the second insertion hole 311 and the third insertion hole 401, the second insertion pin can simultaneously penetrate the sleeve 31 and the foot pipe 4, and the second insertion pin can play a role in connecting the sleeve 31 and the foot pipe 4.

[0046] As shown, Figures 4 to 6 As shown, optionally, the first insertion pin 5 and the second insertion pin (not shown in the figure) are the same in structure, and both the first insertion pin 5 and the second insertion pin comprise a C-shaped limiting piece 51 and a pin rod 52 arranged on the inner side of the C-shaped limiting piece 51. The pin rod 52 is arranged in two first insertion holes 301 or two second insertion holes 311. When the pin rod 52 simultaneously penetrates the main frame 3 and the main rod 2, or simultaneously penetrates the sleeve 31 and the foot pipe 4, the C-shaped limiting piece 51 is wrapped on the outer wall of the main frame 3 and the outer wall of the sleeve 31. At this time, the C-shaped limiting piece 51 can limit the movement of the pin rod 52, so that the connection of the main frame 3 and the main rod 2 and the connection of the sleeve 31 and the foot pipe 4 are more reliable.

[0047] Optionally, the C-shaped limiting piece 51 is a flexible limiting piece. Under the action of an external force, the C-shaped limiting piece 51 can be opened, so that the pin rod 52 can be removed from the inside of the main rod 2 and the inside of the foot pipe 4, and the first insertion pin 5 and the second insertion pin can be conveniently taken off from the main frame 3 and the sleeve 31 respectively. Therefore, the quadrilateral crutch is convenient to disassemble.

[0048] As shown, Figure 8 and Figure 9 As shown, optionally, the upper end of the foot pipe 4 is oppositely provided with two U-shaped holes 402, and the inside of the sleeve 31 is provided with a positioning rod 6 connected with the inner wall of the sleeve 31. The positioning rod 6 cooperates with the two U-shaped holes 402 to prevent the upper end of the foot pipe 4 from moving upward in the inside of the sleeve 31. When the positioning rod 6 is simultaneously located in the two U-shaped holes 402, the second insertion hole 311 on the sleeve 31 and the third insertion hole 401 on the foot pipe 4 are communicated. Therefore, the cooperation of the positioning rod 6 and the two U-shaped holes 402 can quickly realize the positioning of the foot pipe 4, so that the installer can quickly assemble the foot pipe 4 and the sleeve 31.

[0049] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation made according to the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
