The side of the close slider-crank mechanism 302 of seat 304 is provided with grip block 305, described lifting seat 303
One end 310 contacts with the contact surface 311 of grip block 305, described grip block 305 and support platform 200
Bottom is fixing；
Wherein, described slider-crank mechanism 302 includes bent axle, motor, guide rail, slide block, connecting rod, institute
State the bottom of motor hinged by the first hinge 307 with described base 301, the output shaft of described motor with
One end of connecting rod is hinged, and the other end of connecting rod is hinged with slide block, and described slide block moves along guide rail, described in lead
Rail is fixed with frame, and the top of described slide block is hinged with the second hinge 308, described grip block 305 and folder
Holding slide block hinged by the 3rd hinge 309, described clamping slide block moves up and down along clamp rail, described act
Seat up 303 be arranged right below gag lever post 312, one end of described gag lever post 312 is connected with frame regulation,
Described grip block 305 both sides are equipped with guide plate 306.
First hinge of the present invention is passive constraint, its dismounting being mainly used to be easy to slider-crank mechanism 302,
Further, slider-crank mechanism 302 with frame as guide rail, described slider-crank mechanism 302 can only on move down
Dynamic, thus lift lifting seat 303, one end 310 of described lifting seat 303 contacts with grip slipper 304
Face 311 contacts, thus when slider-crank mechanism 302 rises, makes grip slipper 304 with circular arc, ellipse
The direction motion of arc, during decline, move in the direction with elliptic arc, circular arc, thus had both changed sand table
Angle, changes again the height of sand table, it is simple to get a bird's eye view sand table.
Seeing Fig. 3, described grip block 305 and the bottom supporting platform 200 are fixed by connecting portion 400,
Described connecting portion 400 include connecting rod 401, lever ball 402, spring, platform bolt 403, spacing ball 404,
Caging bolt 405, roating sphere 406, housing 407, antivibration pad 408, described grip block 305 clamps institute
Stating connecting rod 401, described connecting rod 401 is fixed with the lever ball 402 in housing 407, described lever
Ball 402 is hinged with described housing 407, the side at the center of the close housing 407 of described lever ball 402
Being provided with arc block 410, the arcwall face of described arc block 410 contacts with described spacing ball 404, described shell
Body 407 is provided with support platform 200 in the side away from described connecting rod 401, and described housing 407 is just to institute
State support platform 200 to go out to be provided with through hole, between described support platform 200 and described arc block 410, be provided with spring,
