Bottom link block 8 is installed, the link block 8 includes two connecting tubes 8.1 and is connected with two connecting tubes 8.1
First baffle 8.3 and second baffle 8.4, two connecting tubes 8.1 formed with the first baffle 8.3, second baffle 8.4
Hollow structure for sliding slot 8.5, support tube 9 is mounted in the sliding slot 8.5, and 9 bottom of support tube is equipped with foot pad 9.3,
9 top of the support tube is equipped with location hole 9.2, and sequence is arranged with multiple support tube axis to 9 side wall of support tube 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 to pass through axis hole 8.2, support tube axis hole 9.1 and connecting hole 1.3 that link block 8 and support tube 9 are fixedly mounted on the connecting portion
On 1.2,4 other end of connecting shaft is threadedly coupled with wing nut 3.
Preferably, the center location of the pin hole 6.2 and the center location 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 6.2 phase of pin hole
Connection, the longer bottom surface of the fishplate bar 6.3 are connected with described sleeve pipe 6.1, and the pin hole 6.2 passes through connecting plate 6.3 and casing
6.1 are integrally formed connection, therefore, make guide sleeve 6 is whole 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, 9 periphery wall of support tube is rectangular configuration, each side wall junction of the support tube 9 is equipped with
Chamfering structure, the sliding slot 8.5 of the link 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 8.4 width of second baffle 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 9 width dimensions of stay tube, two connecting tubes 8.1 are equal to 9 length dimension of support tube, two connecting tubes
8.1 planar structures in face being in contact with the support tube 9, two connecting tubes 8.1 and the first baffle 8.3, second
Baffle 8.4 is integrated connection, it can be seen that, support tube 9 is positioned by the sliding slot 8.5 of rectangular configuration, support tube 9 is risen
To being fixedly connected with and position purpose.
Preferably, the sponges cover 7 is " C " type structure, convenient for being sleeved on casing 6.1.
Preferably, the positioning pin 5 is equipped with mounting cap and the connection end being connected with the mounting cap, it is described
Connect end be mounted on pin hole 6.2 inside, it is described connection end be pyramidal structure, it is described connection 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 equipped with screw thread, the company with mounting cap junction
It connects end to be threadedly coupled with the pin hole 6.2, reduces positioning pin 5 and 9.2 fit clearance of location hole, 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
The side wall that 9 two side walls of support tube are stated with the first baffle 8.3 and the second baffle 8.4 is in contact(As shown in Figure 3-4),
The positioning pin 5 extends up to positioning pin 5 by pin hole 6.2 and withstands on 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 positioning pin 5, is shaken when can prevent support tube 9 as supporting leg.
Preferably, the distance between the distance between adjacent described connecting hole 1.3 and the adjacent support tube axis hole 9.1
It is equal, therefore, as crutch in use, convenient for adjusting the whole height of crutch, as rest legs and feet portion in use, convenient for adjusting
Legs and feet portion placing height has the advantages that easy to adjust, adjustable range is wide, and compatible crutch and legs and feet portion synchronous altitude are adjusted.
Specific work process as crutch in use, support tube 9 is positioned in the sliding slot 8.5 of link block 8, and supports
The axis of pipe 9 and the axis of support frame 1 are arranged in parallel, and are slided by guide sleeve 6 along connecting portion 1.2, and positioning pin 5 is made to be inserted into positioning
In hole 9.2, and the vertical fixation for the realization support tube 9 of first baffle 8.3 for passing through link block 8, make support tube 9 and support frame 1
One, and positioning pin 5 and 9.2 fit clearance of location hole are realized by the connection end of positioning pin 5, improve guide sleeve 6 and branch
The connection tightness of stay tube 9, avoids support tube 9 from shaking, and realization is used as crutch;
As rest legs and feet portion in use, first, by guide sleeve 6 along connecting portion 1.2 to crutch top slide, positioning pin 5
It is disconnected with location hole 9.2, then, support tube 9 is rotated counterclockwise by connecting shaft 4(As described in Figure 4), make support tube 9
The orthogonal setting of axis of axis and support frame 1 limits 9 rotation angle of support tube by first baffle 8.3 or second baffle 8.4
Degree, finally, by along connecting portion 1.2 to crutch basal sliding, one end of positioning pin 5 being made to peak at the side of support tube 9 guide sleeve 6
On wall, 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 will turn
Other seats are erected at the top of cane, on associated support object or non-diseased leg, illness leg is positioned over support frame 1 by patient
On, and comfort is improved by sponges cover 7, therefore, realization is used as rest legs and feet portion, is reduced and is filled at patient's legs and feet by traumatic part
Blood causes wound acid swollen;
During adjusting, 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 patient
Height, arbitrary support tube axis hole 9.1 and connecting hole 1.3 is selected to be coaxially disposed, as crutch in use, when crutch body tune it is short
When, in order to set up the placement of legs and feet portion level or keep certain scaffolding height, using positioned at connecting portion 1.2 close to top
Connecting hole 1.3 using the support tube axis hole 9.1 positioned at support tube 9 close to 9.2 one end of location hole, therefore, has entity conveniently,
As crutch in use, convenient for adjusting the whole height of crutch, as rest legs and feet portion in use, being placed convenient for adjusting legs and feet portion
Highly, have the advantages that easy to adjust, adjustable range is wide, compatible crutch and legs and feet portion synchronous altitude are adjusted.
