With the second positioning region 31, and the annular groove 32 of a winding bracing wire 9 should be equipped with around the radial position of becket bridle 3, in annular groove
32 are equipped with one for fixing the locating slot 33 of bracing wire 9；The bracing wire guiding mechanism 4, it includes one for being fixed on cross bar 7
The fixed ring 41 at place, the fixed ring 41 are installed with stem 42, which is equipped with the connected pathways 43 for allowing bracing wire 9 to pass through,
The connected pathways 43 is opposite with the annular groove 32 around becket bridle 3；By rotating handle 1, the annular groove around becket bridle 3 is then driven
In 32 between any fixed point and the connected pathways 43 of stem 42 spacing change.
As shown in Figure 7, it is preferable that the longitudinal cross-section around the annular groove 32 of becket bridle 3 is in cam face, the ring of cam face
The radius of connected in star 32 changes greatly, to rotate the handle 1 of low-angle, so that it may which the longer bracing wire 9 of movable length provides
It is a kind of more labor-saving to mention line apparatus.
Further, below the connected pathways 43 of stem 42 is arranged at 32 tangent line of annular groove of becket bridle, tangent line mistake
Degree is conducive to the movement of bracing wire 9, and motion profile is more smooth, in addition will mention line apparatus 100 and be installed on 200 vehicle of wheelchair, gas
Spring 8 is installed in the lower section for mentioning line apparatus 100, will pass through channel 43 and is placed at tangent line lower section and is conducive to bracing wire 9 being directed to gas
The position (as shown in figure 19) of spring 8.
Central rotating shaft 2 is fixedly set on cross bar 7, handle 1 and around becket bridle 3 be set in central rotating shaft 2 gear along 22
Two sides, it is preferable that First terrace 16 is equipped in handle 1, by the gear of the First terrace 16 and central rotating shaft 2 along 22 gaps
Cooperation, and first positioning region 12 is wave shape groove；It is described that second step face 35 is equipped in becket bridle 3, by this
The gear of two step surfaces and central rotating shaft 2 is along 22 clearance fits, and second positioning region 31 is waveform flange, the first positioning
The cooperation mutually nested with the second positioning region 31 of portion 12 so that handle 1 and around becket bridle 3 be set in central rotating shaft 2 gear along 22
Two sides, first positioning region 12 are nested using waveform with the second positioning region 31 so that part stress is uniform, and reduction is local
Stress is excessive.
Bracing wire guiding mechanism 4 is arranged in around the outside of becket bridle 3, and wherein fixed ring 41 is fixed on cross bar 7, specifically, such as
Shown in Fig. 3, fixed ring 41 is respectively equipped with first with a notch 411, the two sides of the notch 411 and the lower part for being located at fixed ring 41
Fixing seat 412 and the second fixing seat 413；It is logical that first fixing seat 412 and the second fixing seat 413 is equipped with perforative first
Hole 414, while the second through-hole 415 is equipped in the axial end of the second fixing seat 413；One pin shaft 416 is placed on second through-hole 415
Interior, one end of the pin shaft 416 is equipped with the first threaded hole 418, and first threaded hole 418 and first through hole 415 are opposite, a bolt
417 sequentially pass through first through hole 414 and are spirally connected fixation with the first threaded hole 418, so that pin shaft 416 be made to be fixed on the second fixing seat
In 413 the second through-hole 415, the other end of the pin shaft 416 is equipped with perforative second threaded hole 419 along the vertical direction；One lead
Column 42 is spirally connected with the second threaded hole 419.2 first section of central rotating shaft, endpiece all have several U-shaped notches along its length
27,41 inner wall of fixed ring is equipped with several limit raised lines 422, and the limit raised line 422 is opposite with the U-shaped notch 27 of central rotating shaft 2,
And the equivalent width of its width and U-shaped notch 27, it is fixed on fixed ring 41 on central rotating shaft 2, will not relatively rotate, together
When fixed ring 41 radial part at least provided with a third threaded hole 420, which is located at the U of central rotating shaft 2
The top of type notch 27, a fastening screw 421 are screw-coupled in third threaded hole 420, and the end of fastening screw 421 passes through U-shaped
Notch 27 and the mutual contact of cross bar 7, are fixed on fixed ring 41 and central rotating shaft 2 on cross bar 7.
As shown in figure 4, for beauty, it is preferable that the outer diameter of the sleeve 11 is in cone mouth shape；Simultaneously just for user
In rotating handle 1, several anti-skidding raised lines 13 are equipped in the outer surface of sleeve 11, or preferably inwardly solid in the lateral wall of sleeve 11
If a power assisting device, the power assisting device is thumb button 14, by rotating thumb button 14, then drives the fortune of bracing wire 9
It is dynamic；As shown in figure 5, further, the power assisting device may be force hand handle 15, which extends internally always
Rod segment 151, the end of straight bar section 151 has the grip portion 152 of arc transition, by the lever of grip portion 152 and sleeve 11
Effect, so that more labor-saving in rotating handle 1.
As shown in Figure 8, it is preferable that central rotating shaft 2 is respectively equipped with two positioning rings along the outer diameter end of 22 two sides in gear, is located at
1 side of handle is the first positioning ring 23 and the second positioning ring 24, positioned at being third positioning ring 25 and the 4th around 3 side of becket bridle
Positioning ring 26；The internal chamber wall face contact of first positioning ring 23 and the second positioning ring 24 and sleeve 11, the third positioning
Ring 25 and the 4th positioning ring 26 and the internal chamber wall face contact around becket bridle 3.Using the first positioning ring 23 and the second positioning ring 24 and hand
The inner cavity wall surface of handle 1 positions, and is positioned, is replaced with the inner cavity wall surface around becket bridle 3 using third positioning ring 25 and the 4th positioning ring 26
The entire outer end face of central rotating shaft 2 and handle 1 and the internal chamber wall face contact around becket bridle 3, present invention design reduce central rotating shaft 2
