Shown in Fig. 9 and Figure 10, the inner cavity of pipe clamp 12 can be arranged to horizontal narrow, length up and down straight notch-like, the top of 12 inner cavity of pipe clamp
End arcuation be set as wave groove, it is corresponding, crossbeam corresponding with pipe clamp 12 be it is cylindric, the top of cylinder is arranged to wave groove
Shape, when fixed block 11 is by upward power, position as shown in Figure 9, the wave groove on 12 top of pipe clamp and the wave groove of crossbeam divide
It opens, pipe clamp 12 can slide on crossbeam, when sliding into suitable position, draw fixed block 11, position as shown in Figure 10 still further below
It sets, so that pipe clamp 12 is fixed on crossbeam.
As shown in Figure 1, Figure 2 and Figure 7, fixed block 11 can be arranged on pipe clamp 12 by connectors such as bolts, or pass through
The mode of welding.The top of switch block 13 is connect with 11 ball of fixed block, and fixed block 11 is equipped with a ball groove, and the top of switch block 13 is ball
Shape is simultaneously arranged in the ball groove of fixed block 11.The bottom end of switch block 13 is equipped with opening, and the sliding block 33 being located above is set by elastic component 4
It sets in the opening of switch block 13, when the sliding block 33 in switch block 13 shakes, the top of switch block 13 is swung in fixed block 11.About bullet
Property part 4, can be tension spring, drawstring or other flexible objects.
About component 2 is pulled, this application provides three sets of plan, first, pulling component 2 as shown in Figure 1, Figure 2 and shown in Figure 11
Including 21 and the pulling block 22 of trying to stop people from fighting each other, 21 lower sections for being fixed at pulling block 22 of trying to stop people from fighting each other, the top of pulling block 22 is equipped with fluting, is located below
33 rotary setting pulling block 22 of sliding block fluting in, underlying sliding block 33 is connected with the rotation of component 2 is pulled.Pulling block 22 can be with
Rotary motion is generated with sliding block 33, sliding block 33 can also generate rotary motion with component 2 is pulled, that is, pulling component 2 can be even
Rotation when connected components 3 can not shake.
Second, as shown in figure 12, pulling component 2 includes trying to stop people from fighting each other 21, pulling block 22 and finger frame 23, trying to stop people from fighting each other 21 is fixed at
The lower section of pulling block 22, pulling block 22 and underlying middle sleeve 32 are fixedly installed, and finger frame 23, which is slidably arranged in, tries to stop people from fighting each other in 21, hand
Refer to that frame 23 and underlying sliding block 33 are fixedly installed.When in use, finger is placed on finger frame 23, is started when pulling at
When referring to frame 23, sliding block 33 can slide downward, it can directly with the finger control connection component being placed on finger frame 23
3,。
Third, pulling component 2 includes trying to stop people from fighting each other 21 and pulling block 22,21 lower sections for being fixed at pulling block 22 of trying to stop people from fighting each other, such as Figure 13
Shown, the lateral surface of underlying sliding block 33 is equipped with several longitudinal groove 331, be equipped on the inside of the fluting of pulling block 22 it is several with it is vertical
To the convex block 221 of the sliding setting of groove 331.It pulls downward on and tries to stop people from fighting each other 21,21 rotations of trying to stop people from fighting each other drive pulling block 22 to rotate, then pulling block 22
On convex block 221 rotated with movable slider 33, become the entirety that can not be rotated, therefore entirely connection group due to 3 groups of connection component
Part 3 can rotate in mounting assembly 1.On this basis, as shown in figure 14, it is several fixed to be equipped in the side of longitudinal groove 331
The secondary slot 332 in position, underlying sliding block 33 are connected with the rotation of component 2 is pulled.It, can be with when passenger, which can not access, pulls component
The help of request people from side, pulls downward on pulling block 22, whole at this time then by the rotation of convex block 221 of pulling block 22 to the secondary slot 332 of positioning
The length of a arm-rest frame increases.
It should be understood that above embodiments are only to illustrate the technical solution of the utility model, it is rather than its limitations, right
For those skilled in the art, as long as structural conflict is not present, technical solution illustrated in the above embodiments can be repaired
Change or equivalent replacement of some of the technical features；And all such modifications and replacement, it all should belong to the utility model
