Hollow structure be chute 8.5, support tube 9 is arranged in the chute 8.5, and the bottom of support tube 9 is provided with foot pad 9.3,
The top of the support tube 9 is provided with positioning hole 9.2, and order is arranged with multiple support tube axles to the side wall of support tube 9 from top to bottom
Hole 9.1, two connecting tubes 8.1 horizontal direction be respectively provided with installation connecting shaft 4 axis hole 8.2, the connecting shaft 4 according to
It is secondary that contiguous block 8 and support tube 9 are fixedly mounted on the connecting portion through axis hole 8.2, support tube axis hole 9.1 and connecting hole 1.3
On 1.2, the other end of connecting shaft 4 is threadedly coupled with wing nut 3.
Preferably, the home position of described pin-and-hole 6.2 and the home position of described sleeve pipe 6.1 are located at same horizontal line
On, trapezium structure that it is boring that the connecting plate 6.3, which is, the shorter bottom surface of the connecting plate 6.3 and the phase of pin-and-hole 6.2
Connection, the longer bottom surface of the fishplate bar 6.3 are connected with described sleeve pipe 6.1, and the pin-and-hole 6.2 passes through connecting plate 6.3 and sleeve pipe
6.1 are integrally formed connection, therefore, make guide sleeve 6 is overall to have the resistance to compression non-deformability mitigated, can bear human body by helping
The pressure of the application of frame 1 is held, prevents crutch overall deformation.
Preferably, the periphery wall of support tube 9 is rectangular configuration, each side wall junction of the support tube 9 is provided with
Chamfering structure, the chute 8.5 of described contiguous block 8 is rectangular configuration, and the first baffle 8.3 connects with the second baffle 8.4
It is connected on the different end faces of two connecting tubes 8.1, the first baffle 8.3 and the width of second baffle 8.4 are equal and little
In the 1/3 of two connecting tubes 8.1 length, the distance between the first baffle 8.3 and the second baffle 8.4 are equal to branch
The distance between the width dimensions of stay tube 9, two connecting tubes 8.1 are equal to the length dimension of support tube 9, two connecting tubes
The planar structure in 8.1 faces being in contact with the support tube 9, two connecting tubes 8.1 and the first baffle 8.3, second
Baffle plate 8.4 is integrated connection, it can be seen that, support tube 9 is positioned by the chute 8.5 of rectangular configuration, support tube 9 is risen
To being fixedly connected with and position purpose.
Preferably, described sponges cover 7 is " C " type structure, it is easy to be sleeved on sleeve pipe 6.1.
Preferably, described alignment pin 5 is provided with mounting cap and the connection end being connected with the mounting cap, it is described
Connect end be arranged on pin-and-hole 6.2 inside, it is described connection end be pyramidal structure, it is described connect end cross-sectional diameter dimension by
The one end that is connected with mounting cap is gradually reduced to the other end, and the connection end is provided with screw thread, the company with mounting cap junction
Connect end to be threadedly coupled with the pin-and-hole 6.2, reduce alignment pin 5 and the fit clearance of positioning hole 9.2, improve guide sleeve 6 and support
The connection tightness of pipe 9.
Preferably, when orthogonal with the support frame 1 after adjusting the support tube 9 and being rotated by connecting shaft 4, institute
9 two side walls of support tube are stated to be in contact with the side wall of the first baffle 8.3 and the second baffle 8.4(As shown in Figure 3-4),
The alignment pin 5 extends up to alignment pin 5 by pin-and-hole 6.2 and withstood in the side wall of support tube 9, is used when as rest legs and feet portion
When, positioning is supported to support tube 9 by alignment pin 5, rocked when can prevent support tube 9 as supporting leg.
Preferably, the distance between the distance between adjacent described connecting hole 1.3 and adjacent described support tube axis hole 9.1
It is equal, therefore, as crutch in use, being easy to adjust the whole height of crutch, as rest legs and feet portion in use, being easy to adjust
Legs and feet portion placing height, there is the advantages of easy to adjust, adjustable range is wide, compatible crutch and legs and feet portion synchronous altitude regulation.
Specific work process, as crutch in use, support tube 9 is positioned in the chute 8.5 of contiguous block 8, and support
The axis of pipe 9 is set with the diameter parallel of support frame 1, is slided by guide sleeve 6 along connecting portion 1.2, makes the insertion positioning of alignment pin 5
In hole 9.2, and the vertical fixation of support tube 9 is realized by the first baffle 8.3 of contiguous block 8, make support tube 9 and support frame 1
One, and alignment pin 5 and the fit clearance of positioning hole 9.2 are realized by the connection end of alignment pin 5, improve guide sleeve 6 and branch
The connection tightness of stay tube 9, avoids support tube 9 from rocking, and realization uses as crutch;
As rest legs and feet portion in use, first, being directed to set 6 along connecting portion 1.2 to crutch top slide, alignment pin 5 is with determining
Position hole 9.2 is disconnected, and then, support tube 9 passes through the rotate counterclockwise of connecting shaft 4(As described in Figure 4), make the axis of support tube 9
With the orthogonal setting of axis of support frame 1, the anglec of rotation of support tube 9 is limited by first baffle 8.3 or second baffle 8.4,
Finally, by being directed to set 6 along connecting portion 1.2 to crutch basal sliding, one end of alignment pin 5 is made to peak at the side wall of support tube 9
On, the fixation of support tube 9 is realized, in use, foot pad 9.3 is contacted with ground and support frame 1 is parallel to ground, patient is by crutch
Top is erected on other seats, on associated support thing or non-diseased leg, and ill leg is positioned over support frame 1 by patient
On, and comfortableness is improved by sponges cover 7, therefore, realization uses as rest legs and feet portion, reduces and is filled at patient's legs and feet by traumatic part
Blood causes wound acid swollen;
During regulation, by by connecting shaft 4 from axis hole 8.2, support tube axis hole 9.1 and connecting hole 1.3 take out when, according to the body of patient
Height, select any support tube axis hole 9.1 and connecting hole 1.3 to be coaxially disposed, adjusted in short-term as crutch in use, working as crutch body,
In order to set up the horizontal placement in legs and feet portion or keep certain scaffolding height, the company positioned at connecting portion 1.2 close to top is used
Hole 1.3 is connect, using the support tube axis hole 9.1 positioned at support tube 9 close to the one end of positioning hole 9.2, therefore, has entity convenient, makees
For crutch in use, being easy to adjust the whole height of crutch, as rest legs and feet portion in use, being easy to adjust legs and feet portion placement height
Degree, there is the advantages of easy to adjust, adjustable range is wide, compatible crutch and legs and feet portion synchronous altitude regulation.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
