The specific embodiment
With shown in the accompanying drawing 3, be stereogram of the present utility model, three-dimensional exploded view and cutaway view as accompanying drawing 1, accompanying drawing 2.As shown in the figure, the utility model comprises a Brake Block 1 and a holder 2.Wherein, this Brake Block 1 comprises a lamellar body 11 and a lid 12, is provided with through hole 111 and fixed leg 112 in this lamellar body 11, and this lid 12 is provided with through hole 121, and for the screw 122 that closes in fixed leg 112, the root edge of lid 12 is equipped with a bolt 13;
One air pressure rod 14, the top of the lamellar body 11 of Brake Block 1 is fixed on its top, the bottom of air pressure rod 14 is connected in a rotating shaft 15, and be provided with a fixing hole 151(present embodiment in these rotating shaft 15 centers and be made as square opening), and in rotating shaft 15 extensions one swing arm 152, and the through hole 111,121 that makes these rotating shaft 15 two ends be embedded at lamellar body 11 and lid 12 respectively constitutes the location;
This holder 2 is provided with a lamellar body 21, is provided with plural fixing hole 211 in this lamellar body 21, and is provided with a horizontal fixed bar 22(square pole corresponding to rotating shaft 15 fixing holes 151 in these lamellar body 21 middle positions);
Combination by aforementioned components, in when assembling the lid 12 of Brake Block 1 is covered be locked in lamellar body 11 after, this Brake Block 1 is locked in movable position (as the headrest of seat), again holder 2 is locked in fixed position (as the chair back of seat), make its horizontal fixed bar 22 wear the fixing hole 151 that is fixed in rotating shaft 15, to constitute concealed angular adjustment apparatus.When using,, Brake Block 1 set rotating shaft 15 is rotated, cooperate the flexible and spacing of air pressure rod 14, thereby reach the angle adjustment at movable position by the pulling of movable position.And the bolt 13 that can be worn by lid 12 bottoms of this Brake Block 1 is flexible, constitutes the holding of swing arm 152 of countershaft 15, thereby constitutes the adjustment of the rotational angle of rotating shaft 15.
