In view of this, the creator has improved it by thinking positively, and provides a wheelchair system consisting of a chair body, a group pillar and a group of crawler wheels. The chair body is provided with a lever and a rear An axle shaft; the pillar is formed by the upper pillar and the lower pillar being connected by the fifth tip member, the top end of the upper pillar is pivotally connected to the crossbar, and the bottom end of the lower pillar is pivotally connected to the crossbar of the crawler wheel; The front wheel of the track wheel is pivotally connected to the second hole of a plate, and the first hole of the plate is pivotally connected to the rear wheel shaft, so that the wheelchair of the present invention can also travel on the stairs. [Embodiment] The foregoing and other objects, features and advantages of the present invention will become more apparent from the claims. Please refer to the figure-picture, which is a modification of the wheelchair, which consists of a chair body 1, a group of pillars 2 and a set of crawler wheels 3. Please refer to the second ® as shown in the second ®, the frequency 1 second-year wealth - support correction, a front foot 12, a rear foot 13 and a seat 14 between the two front feet 12 and the second rear legs 13, two support 4 M286664 hand 11 The first end piece 111 is pivotally connected to the closed end 1131 of the inverted C-shaped connecting base 113 and the outer side of the rear (four) 13 respectively, so that the armrest η and the connecting base 113 can be the first The tip ill is pivoted for the axis, and the open end 1132 of the two connecting seats 113 is respectively connected to the appropriate position of the forefoot 12 by the second tip member 112, so that the forefoot 12 can pivot with the second tip member 112 as the axis. In order to facilitate folding into a smaller volume, as shown in the third figure. Referring to the second figure, the bottom side of the top end of the front leg 12 is abutted against the first tip piece 111. The upper side of the top end of the front leg 12 is appropriately abutted by the bottom side of the joint portion 11 to position the front leg 12, and The front side of the bottom end of the front leg 12 has a front wheel 121. The top ends of the two rear legs 13 respectively have an extension rod 131 for extending the length of the rear leg 13. The two extension rods 131 are respectively constrained by a buckle 132 disposed on the rear leg 13. The structure of the buckle 132 is as shown in the fourth figure. And detailed later, in addition, a second seat 133 is respectively fixed at the middle of the second rear leg 13 respectively, and the ear seat 133 is respectively provided with a third tip piece 141 for pivoting the rear end of the seat 14 to the middle of the seat 14 at the fourth place. The tip member 142 is pivotally connected to the front leg 12, and a cross bar 134 is fixed between the two ear seats 133. The rear ends of the rear legs 13 are respectively connected with a rear wheel 136 by a rear wheel shaft 135, and the rear ends of the rear wheel shafts 135 are respectively fixed to A first hole 151 of a plate 15 and a second hole 152 of the plate 15 are axially coupled to the front wheel 31 of the track wheel 3. The set of pillars 2 is composed of two pillars 2, and each pillar 2 is formed by a top pillar 21 and a lower pillar 22 being framed by a fifth tip member 23. Referring to the first and fourth figures, the upper pillar 21 is shown. The top end is connected to the crossbar 134, so that the upper strut 21 can pivot about the crossbar 134. The inner side of the upper strut 21 is fixed with a buckle 132. The buckle 132 has an elastic member 1321 and a bolt 1322. The end of the element 1321 abuts against the blocking portion 1323 of the bolt 1322, and the other end of the elastic member 1321 abuts against the inner wall of the buckle 132, so that the bolt 1322 has the ability to be reset due to the elastic member M286664 1321, the bolt 1322-end In the first hole 1324, the other end of the bolt 1322 protrudes from the second hole 1325 and is pivotally connected to a pull block 1327 by a sixth tip member 1326; the bottom end of the lower post 22 is pivotally connected to the cross bar 33 of the track wheel 3, The lower pillar 22 can be pivoted by the crossbar 33 as an axis. The lower pillar 22 is provided with a first bolt hole 221 and a second bolt hole 222. The first bolt hole 221 is located on the inner wall surface of the lower pillar 22, and the lower pillar 22 is provided. The first bolt hole 221 corresponds to the first hole 1324 when the upper pillar 21 is in line; the second bolt hole 222 is located on the upper wall of the lower pillar 22 When the lower pillar 22 and the upper pillar 21 are bent at an appropriate angle, the second bolt hole 222 corresponds to the first hole 1324. Therefore, the first bolt hole 221 and the second bolt hole 222 can be connected to the upper pillar 21 The pivoting of the lower strut 22 corresponds to the first hole 1324 for the bolt 1322 to pass through, and the upper strut 21 and the lower strut 22 are fixed. Referring again to the fifth figure, the pull block 1327 is pulled so that the bottom portion 1328 of the pull block 1327 abuts against the outer turn of the buckle 132, and the bolt 1322 is disengaged from the first bolt hole 221 by movement. The set of crawler wheels 3 is composed of two crawler wheels 3, and each of the crawler wheels 3 is respectively located at the rear side of the rear leg 13, as shown in the first and sixth figures, which has a front wheel 31, a rear wheel 32, and a front wheel 31. The rear wheel 32 is respectively axially connected to a C: font ear block 311, 321 , and a screw block 34 is arranged between the ear block 311 and 321 for adjusting the tightness of the crawler belt 35 between the front wheel 31 and the rear wheel 32. A cross bar 33 is fixed between the two ear blocks 311. The effect of this creation will be described in detail later. Please refer to the first figure. The front wheel 121 and the rear wheel 136 of the present invention can be used to land on the ground; if it needs to travel on the stairs, please Referring to the sixth figure, the bolt 1322 is detached from the second bolt hole 222, and the lower pillar 22 and the upper pillar 21 can be aligned, so that the first bolt hole 221 corresponds to the first hole 1324. The upper pillar 21 and the lower pillar 22 are fixed. 6 M286664 This group of pillars 2 can spur the set of crawler wheels 3 to travel on the stairs.
