Embodiment
With reference to specific embodiment, the utility model is described in further detail：
Referring to accompanying drawing 1 to accompanying drawing 3, a kind of adjustable wheelchair rear wheel support member, including connector 1, the tune for connecting trailing wheel 4
Pole 2 and position-limit mechanism（Preferably, trailing wheel 4 may connect to the end of adjusting rod 2）, the wherein horizontal direction of connector 1 is provided with one
Cross through hole 11 is used to be connected with wheelchair frame, is provided with a fixing hole 12 in the radial direction of cross through hole 11, fixing hole 12 coordinates
Connector 1 is connected by hexagon socket head cap screw with wheelchair frame；An installation through-hole 13 is also provided with connector to pass through for adjusting rod 2
（Specifically, the incline direction of installation through-hole 13 is set）, adjusting rod 2 will regulation by the flexible lock pin 33 on connector 1
Bar 2 is limited in the installation through-hole 13 of connector 1, and connector 1 is provided with a screwed hole 14 axially mutually to be hung down with adjusting rod 2, spiral shell
Pit 14 and adjusting rod 2 are radial parallel；The upside of connector 1, which is provided with some anti-slip veins and slammed for people's pin, stops wheelchair.
It is spaced on adjusting rod 2 and is uniformly provided with several positioning holes 21（Six positioning holes 21 can be provided with）, and position-limit mechanism bag
Include coordinate with positioning hole 21 flexible lock pin 33, for pulling the flexible drawing article 34 of flexible lock pin 33, for guiding flexible lock
The flexible guide rod 31 of pin 33 and reset back-moving spring 35 and pole cap 36 for driving flexible lock pin 33 to stretch out, guide rod 31 is with stretching
Connected between contracting lock pin 33 by flange 32（Guide rod 31, flange 32 and flexible lock pin 33 can form integrative-structure）, and drawing article
34 be U-shaped structure, and the both side ends of drawing article 34 are extended with extension laterally, and is formed with two outsides of drawing article 34 some
Bar anti-slip veins, people are made to pull drawing article 34 by the effect of extension and anti-slip veins, while the middle part of drawing article 34 is provided with one
Through hole is for flexible lock pin 33 by the way that and coordinating with flange 32 prevents flexible lock pin from moving on, and flexible lock pin 33 may extend to
