Field of the Invention The present invention relates to an adjustment mechanism, and more particularly to an adjustment machine for a chair that is mounted on a seat for allowing the seat to be displaced forward and backward relative to the foot of the chair. 】 In order to make the existing chair have better appetite, it is more comfortable to use. The existing chair usually has a lifting adjustment mechanism on the seat to enable the occupant to adjust the chair according to the height. The height of the seat; or the shifting of the shifting sound after the movement of the handle on the handle of the 3rd and 10th, and the τ鳘 mechanism, so that the occupant can change the position of the handrail as needed. However, since the conventional chair does not have the function of moving the body position back and forth, the occupant must move the whole (4) Μ (4) Μ (4) to the distance of the table, and the conventional zipper and the clerk have poor applicability, and there is still room for improvement. SUMMARY OF THE INVENTION The purpose of the present invention is to provide an adjustment mechanism for a chair that can be moved in the front-rear direction with respect to the leg of the chair. Another object of the present invention is to provide an adjustment mechanism for a chair that is highly versatile. ^ In order to achieve the above purpose, the present invention is not limited to a chair adjustment mechanism, and the mouth is on a seat and can be combined with a chair set, and the seat can be relative to the seat. The foot moves in the front and rear direction.杪 杪 。. The smashing mechanism includes: a pull unit, 5 1363606 - slave unit, _ adjustment sheet ^ and -m pieces. The pulling unit is slidably disposed on the bottom side of the seat in the front-rear direction, and has an obliquely extending oblique sliding groove, the oblique sliding groove has an opposite first front end and a rear end Second end. The driven unit is slidably disposed in the left-right direction between the bottom side of the seat and the pulling unit and has at least a convex portion protruding from the bottom side thereof and correspondingly protruding in the oblique sliding groove, the & The portion can slide back and forth between the first end of the oblique sliding groove and the second end. The adjusting unit comprises a first ^=and-second adjusting member 纟, the first adjusting member penetrates in the front-rear direction/month: on the seat, and has a plurality of front and rear spaced intervals recessed in the vicinity thereof: from the early side The second adjusting member is disposed on the side of the driven unit adjacent to the first adjusting member, and is capable of being separated from the one of the facing first adjusting members. The first positioning member is configured to slidably combine the first adjusting member on the seat, and ί=the foot assembly. The second adjusting member is movable relative to the first adjusting member between the locking and unlocking positions; when in the locking position, the convex portion is located at the first end of the obliquely moving groove, and the tooth of the wide 70; Pulling the pulling unit, the driven unit will be inclined to slide obliquely: while moving relative to and moving the second adjusting member, the driven unit = the second end of the oblique sliding groove, and The second adjustment will leave the place: = yuan:::: solution r position, the seat can be combined with the first, piece: foot along the front and rear::: in the first adjustment piece, [positioning piece and chair [implementation] # "The invention" ># 'j describes other technical content, features and effects, at the bottom of the 6 丄: () seat 9 ' and the first adjustment of a set of screws and nuts worn on the seat 9 The pieces 31 are grouped together to "on the first guide groove 91 of the first adjustment member 3 seat 9. In addition, in the embodiment, the first fixed #= and the first adjusting member 31 can be tilted by obliquely sliding with the leg 21 I:::/ by means of screwing, screwing, or the like. The driving member moves the fourth and second adjusting members 32 to move between the locking position and the unlocking position with respect to the first adjusting member 31 and the first positioning member 33 and the leg. See Figure 3 and Figure 4. When in the locked position, the pulling unit W limiting members 13 are respectively located at the front end 115 of the corresponding sliding groove U3. The convex portion 211 of the follower 21 protrudes from the first end m of the oblique sliding groove "4. The second adjustment member 32 is snapped onto the facing slot 311. Refer to Figure 5 and Figure 6. When the pulling force pulls the pulling member u forward, the pulling member u will slide forward, so that the pulling unit w slides the groove 3 to relatively move to abut against the stopper 13 at the rear end thereof, and the first elastic member 12 is caused Being = Shen has the power of recovery. By tilting the slot m to the mechanism "again. The tenth moving member i! moves the convex portion of the traction follower 2 i together with the follower member 21 and the second adjusting member 32 to the right; the convex portion of the follower member 21 will be shifted from the oblique direction to the month. The end 11 7 is moved to the second end 118, the second adjusting member 32 will leave the corresponding tooth groove 311, and the second elastic member 22 of the driven unit 2 is broken to have a restoring force to the left. At this time, the second adjustment member 32 is located at the unlocked position. In the unlocked position, the seat 9 can be biased to drive the pulling unit 1, the driven single opening 9, 0 i, the second adjusting member 32 relative to the first adjusting member 31 and the first fixed frame JOJCHK) Figure. Fig. 2 is a perspective view showing the combination of the preferred embodiment. Figure 3 illustrates a top plan view of the preferred embodiment illustrating that the second adjustment member is in a locked position relative to the first adjustment member. The second adjustment member is in a locked position relative to the first adjustment 35 member. Figure 5 is a plan view showing the second embodiment of the second embodiment of the preferred embodiment in an unlocked position relative to the first adjustment member. The following is a view of the bottom view of the preferred embodiment, illustrating that the two parts are in an unlocked position with respect to the first adjustment member.
