The specific embodiment

For clearly demonstrating the technical scheme in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.

Referring to Fig. 1, comprehensive adjusting handrail is made up of loam cake 1 and armrest body 2; Armrest body 2 comprises adjustable plate main body 3 and the adjusting rack body 4 that connects loam cake 1, as shown in Figure 2.

The structure of adjustable plate main body 3 comprises as shown in Figure 3: fixed head 31, inner slider 32, outer slide plate 33.

Fixed head 31 is circular, and two elasticity fixture blocks 34 with symmetry.

Inner slider 32 is square, both sides have elasticity fixture block 34, inner slider 32 has the circular groove that matches with fixed head 31, has the draw-in groove 35 that matches with elasticity fixture block 34 in the groove, fixed head 31 is installed in the circular groove of inner slider 32, and elasticity fixture block 34 holds with draw-in groove 35, after fixed head 31 is fixed on connecting rod 47 by screw, outer slide plate 33, inner slider 32 can rotate along fixed head 31, because elasticity fixture block 34 adopts plastic material, can deform, in rotation process, can in each draw-in groove 35, snap in ejection, thus the left and right sides position adjustments of loam cake 1 that realization connects.

Outer slide plate 33 is square, has the square groove that matches with inner slider 32, has the draw-in groove 35 that matches with elasticity fixture block 34 in the groove, and elasticity fixture block 34 holds with draw-in groove 35, connecting rod 47 is in chute 36, and after fixed head 3 was fixedly connected on the connecting rod 47, outer slide plate 33 can move forward and backward, its chute 36 moves with respect to connecting rod 47, thereby the front and back position of loam cake 1 that realization connects is regulated.

Outer slide plate 33 is connected with loam cake 1, and fixed head 31 is connected on the connecting rod 47 of regulating rack body 4, and connecting rod 47 coupling hooks 41 as shown in Figure 2.

Hook 41 connects spring 411, has stuck point 412 as shown in Figure 4 on the hook 41.Hook 4 chute 36, the location-plates 44 that pass outer slide plate 33 are packed in as shown in Figure 6 the chute 45, and the stuck point 412 on the hook 41 is held in the teeth groove 46, and outer slide plate 33 and location-plate 44 are slidingly connected.

Hook 41 is installed into chute 45, and button 42 is packed on the opening of location-plate 44, and its position is pushed down by briquetting 43 on hook 41, and contacts with hook 41.

Also have C type clamp 48 on the armrest body 2, be used to install sheathing, be installed in the outside of armrest body 2, block teeth groove 46.

After armrest installs, after pressing the button 42, depress hook 41, spring 411 shrinks, hook 41 moves, and stuck point 412 shifts out from teeth groove 46, and hook 41 moves along chute 45, realize the up-down adjustment of seat, after moving to the appropriate location, release button 42, spring 411 drive hook 41 and reset, stuck point 412 snaps in the teeth groove 46, thereby realizes the up-down adjustment of seat.
