Please consult Fig. 1 simultaneously, shown in 2, the utility model mainly is provided with a bearing 1, this bearing 1 is by last,

lower base

11,12 form, wherein this upper pedestal 11 generally is the Jiong type, its surface is provided with two vertical set bolts 111,112, and the front end sleeve of lower base 12 is equipped with a spring 121, the surface is provided with an open-work 122, the bottom then is provided with a sleeve 13, this sleeve 13 is established one and is axially cutd open hole 131, be respectively equipped with the intermediate plate 133 that wears for bolt 132 in cuing open 131 both sides, hole, and articulate a fastener 134 and a fixed bar 135 respectively in bolt 132 two ends, wear the open-work 122 that is exposed to lower base 12 after making oil hydraulic cylinder 14 be placed on this sleeve 13, on being somebody's turn to do,

lower base

11,12 with after a latch 15 mutual pivot joint combinations, one control lever 16 wears the microscler open-work 113 of the vertical plane of upper pedestal 11, with the pressing of the telescopic section 141 of controlling 161 pairs of oil hydraulic cylinders 14 of its front end plate body, constitute oil hydraulic cylinder 14 on, the following adjustment moved.

The bottom of one seat cushion 2 is provided with a base 21, the bottom of this base 21 is provided with a gear 22, and a lamellar body 31 is extended in the bottom of a chair back 3, it for example in illustrated embodiment L shaped lamellar body, these lamellar body 31 front ends are established a gear 32, the gear 22 of this base 21 and the gear 32 of lamellar body 31 are placed on the bolt 111 on upper pedestal 11 surfaces of bearing 1 respectively, after 112, constitute being meshing with each other of gear 22 and gear 32, and the both sides of the chair back 3 are respectively equipped with the handrail 33 of symmetry, and be provided with the handle 34 of bending in handrail 33 front ends, make this handle 34 be able to be clamped on behind horizontal or the stubborn folding clamp grooves 23 of seat cushion 2 both sides downwards.

The bottom of this gear 22 is provided with several balls 221 and a packing ring 222, and the upper and lower end of this gear 32 is respectively equipped with packing ring 321,322 and ball 323, makes the rotation of two

gears

22,32 comparatively smooth and easy.

Combination by aforementioned components, when the user is seated on the seat cushion 2, and when with hand-held handrail 33 health one side being twisted, will be because of the interaction of

gear

22,32, seat cushion 2 is rotated to opposite side, thereby constitute the effect of twisting body-building, and when not using twisting body-building, then can fastener 134 is lax, make oil hydraulic cylinder 14 free to rotate and drive the chair back and become ipsilateral rotation with seat cushion, recover general office chair state, and push oil hydraulic cylinder 14, to adjust the seat height by control lever 16.

See also shown in Figure 3, the utility model is after combination,

gear

22,32 is and is meshing with each other, so, when the chair back 3 or seat cushion 2 rotations, can make two gears be the rotation of different directions mutually, the seat cushion 2 and the chair back 3 are twisted in the opposite direction, and, can make whole twisting action be able to steady, smooth and easy, comfortable because the surface of

gear

22,32 is respectively equipped with ball 221,323.

See also shown in Figure 4, the front bottom end of handrail 33 of the present utility model is provided with a fixed head 331 with connecting

hole

3311,34 of the handles of its extension are provided with the steel ball 342 with spring 341 in terminal, when making handle 34 horizontal, be fastened in connecting hole 3311 by steel ball 342 and form fixing, and the clamp grooves 23 of seat cushion 2 both sides, it is a U-shaped seat, vertical plane in the U-shaped seat is provided with a bolt 231, make when handle 34 is stubborn downwards to be rolled over, set the open-work 343 of these handle 34 bending places and form fixing by bolt 231.

See also clip structure of the present utility model shown in Figure 5, end in the intermediate plate 133 of sleeve 13 is provided with a fastener 134, fastener 134 is locked in bolt 132, and make these bolt 132 1 ends be locked on fixed bar 135, when this fastener 134 is in relaxed state, the intermediate plate 133 of sleeve 13 is opened, therefore the telescopic section 141 of oil hydraulic cylinder 14 can rotate with seat, constitute the user mode of general office chair, and when fastener 134 when fixed bar 135 directions are pulled, then because of the holding of its prominent point 1341, make intermediate plate 133 lockings, oil hydraulic cylinder 14 is tightening state by sleeve 13 lockings, makes seat constitute body-building twisting effect.

As shown in Figure 6, the utility model is when practical operation, and the user is held in handle 34 to hold, and to side twisting, seat cushion 2 is rotated to opposite side because of the interaction of

gear

22,32 chair back 3, with the sway one's hips effect of body-building of formation.
