Description of the invention (1) [This invention belongs to those who provide mechanical structural devices. [Previous technology] In order to make wheelchair occupants comfortable to lean and have many types, if it is a structural adjustment that controls the mechanical, pneumatic, or electric adjustment methods and is on a private wheelchair, it cannot be outside. Type of adjustment on a wheelchair, but the danger of pneumatic cylinders will also increase. Therefore, it belongs to 1 326 1 9 (US4, 968, 0 5 1). The most important thing is that the telescopic support rod is pivoted on the backrest. (Strut) in the sleeve on the back of the guard, and then the block 'and then on the backrest buckle (trigger means') is by the snap device can be snapped in or out of the branch to be in the sleeve Technical field of free telescoping] The backrest of a wheelchair can be adjusted by 1 degree of tilt. The back of the machine has an operation that can adjust the tilt sound. At present, it can be seen that the second structure is provided to distinguish the structure. There are two adjustment controls for the sophomore structure. The structure is most convenient to operate with a knife. However, it is used in general ordinary machinery & wheel = system application, although it can be applied to :: ^; after long-term use, it is easy to occur = pass machinery Wheelchair overall Weight. Mechanical adjustment structure type that is ineffective, such as Yasunori 374017 (US6,224,156) No. 1 a surface with threads or a plurality of one can be 'and the support post is placed on a pivot on the chair at On the side of the casing pipe, a spring is pushed = a lever installed at the upper grip (handgrip), and the steel cable of the trigger device is connected to the inlay, and the cable is pulled or relaxed to make the inlay Threads or notches on the struts allow positioning of the supporting poles, which in turn can adjust the tilt of the backrest

Description of the invention (2) However, although the above-mentioned adjustment structure is simple, except that the backrest cannot be adjusted steplessly, the angle of the backrest is tilted backwards. The embedded depth between the end and the notch of the support rod is insufficient, which causes the failure to appear when it is too late to be caught in the notch, thereby causing danger to the occupant. · In addition, there is a patent such as Announcement No. 1 3 559, which is provided with a free end of a connecting rod 20 pivoted on the backrest and passed through a clip provided in a fixed seat 62 fixed on the armrest. The engine mount 64 and the through hole on the embedded plate 67, and the lower end of the clip engine seat 因 is fixed, and the lower end of the embedded plate 67 is abutted on the clip engine seat 64, and then the support rod 20 An elastic spring 6 8 ′ is set between the clamp base 6 4 and the embedded plate 6 7, and the elastic rod of the embedded plate 6 7 is pushed by the spring w, so that the connecting rod 20 is penetrated by the embedded plate 67. The skew of the hole is blocked, thereby preventing the connecting rod 20 from being telescopically moved. However, if the cable 71 is pulled or the connecting rod 78 is pulled by the embedded plate 67 to be squared two, the through hole of the embedded plate 67 and the clamping engine The through hole of the seat 64 is the same inch on the centerline, that is, the connecting rod 20 can be freely extended and retracted to tilt the backrest. However, because the connecting rod 20 is extended in the armrest, it is extremely easy for the occupant's elbow to be The force of the collision and the pushing of the embedded plate 67 by the spring 68 only: the clamping force generated by the connecting rod 20 is really insufficient and there is a risk of slippage ' Occupant dangerous. [Summary of the Invention] It is necessary to improve the stability, safety and operation of the aforementioned conventional method.

Description of the invention (4) 321 makes the steel cable 41 with narrow upper and lower wide buckle device 4 The end cable 41 passes through the upper end of the slider 32 and is provided with a convex portion 323, so that the convex 3 1 b corresponds to The up-and-down linear movement set on the inner wall surface, at the same time, creates a downward addition to the slider 32, and the slider 32 is mounted on the slider 3, and the two inserts 3 4 are mounted on the space 3 1 3, The space 3 11 of the two insert pieces 34 at the lower end of the two insert pieces 34 and the lower end of the outer piece 34 of the two insert pieces 34 are provided with a perforation 315 that is engaged with a and penetrated through the housing 31a. At the same time, after the pole sleeve 2 1 fixed on the back is put on, the screw 4 is used to pass through the sleeve at the back of the skeleton 1 at the same time. Secondly, the latching devices 4 which are embedded in the upper ends of the sliders 3 2 and the backs of the two sides are turned backwards so that the steel can make the sliders 3 2 up and down. Therefore, please refer to the third ladder shape. The inserting hole 322 into which the other body 42 can be inserted is to make the steel 'then the convex portions 32 3 on the front and back sides of the slider 32 can be guided in the sliding groove 314 of the housing 31a and the cover body, so Therefore, the slider 32 can be used as the elastic element 331 installed in the space 31 2 to elastically push. On both sides of the inclined surface 321, two embedded upper cymbals are arranged next to each other and lean against the inclined surface 321, and a bow το member 33 is provided. The tops of the upper ends of the two pairs of embedded pieces 34 are relatively outwardly inclined, and correspondingly The abutting convex part 3 1 6 is convexly protruded on the two side walls, and the middle part of the surface is supported, and then two insert holes 341 ′ are provided, and a supporting rod 35 is provided by the housing 31 = through two ridges 3 4 After the locking holes 3 4 j are formed, the upper end of the support rod 35 is pivoted to the backrest 2 and the two outer shells 31b are pivoted to the upper wire 4 after the shell 31a covers the dagger 31b and the shell 3la. The other end of 1 is connected to the trigger device 4 provided on the handle, so when the cable 4 1 cooperates with the elastic element 3 3 1, it moves.
