When user's desire adjustment shank leans on 20, only need shank by 20 pullings (as the direction that arrow indicated among Fig. 3) forward, so that the screens groove 114 that the fin 124 at second junction surface 121 breaks away from first junction surface 111, this moment, spring 40 compressed along the microscler through hole 125 at second junction surface 121 is mobile backward because of rivet 50, therefore, shank can pivot with respect to seat board 10 by 20, and by restoring force by spring 40, make fin 124 can be fastened on the screens groove 114 of diverse location, shank is leaned on 20 can be according to user's demand, and be fixed on the diverse location, carry out the section adjustment that shank leans on.

Describe second embodiment of the present utility model in detail with reference to Fig. 6 to 8.

As shown in Fig. 6,7 and 8, according to second embodiment of the present utility model, seat board 10 comprises a pair of first junction surface 211, and shank comprises a pair of second junction surface 221 by 20.Wherein Fig. 7 shows first junction surface 211 on seat board 10 the right and second junction surface 221 that shank leans on 20 left sides respectively.

As shown in Figure 7, first junction surface 211 be the position in seat board 10 the place aheads 212 and arranged on left and right sides, and have a cylindrical pivot 213, be formed with a plurality of screens grooves 214 on the circumference of pivot 213.

Second junction surface 221 is that 20 both sides are leaned at shank in the position, and tool one is roughly the pivot accommodation section 223 of oval inner concavity.Pivot accommodation section 223 is that the position is in the position corresponding to the pivot 213 at first junction surface 211, its width is slightly larger than the width of the pivot 213 at first junction surface 211, and the place, interior perimeter surface the place ahead of pivot accommodation section 223 has the fin 224 of the screens groove 214 at an engaging first junction surface 211.221 centers, second junction surface have a microscler through hole 225, when first junction surface 211 is pivoted to second junction surface 221, and the microscler through hole 225 at a rivet 50 ' pass second junction surface 221 and the hole 215 of inserting the pivot 213 that is fixed on first junction surface 211.

As shown in Figure 7, shank is provided with a pair of lid member 230 that is used for covering second junction surface 221 by 20, lid member 230 be formed be used for holding a spring 40 ' holding tank 231, holding tank 231 has a recess 232, the width of recess 232 is substantially equal to the length of microscler through hole 225, and the position of recess 232 is the positions corresponding to microscler through hole 225.

As shown in Figure 8, after second junction surface 221 is bonded on first junction surface 211, with rivet 50 ' pass the microscler through hole 225 at second junction surface 221 and be fixed on the hole 215 at first junction surface 211, so that second junction surface 221 can slide on the length direction of microscler through hole 225 with respect to first junction surface 211, the person of connecing, with be equipped with spring 40 ' lid member 230 cover and be fixed on the below at second junction surface 221, its medi-spring 40 ' an end abut against rivet 50 ', and the other end abuts against the inside at second junction surface 221 so that spring 40 ' place the inner and rivet 50 in second junction surface 221 ' between.

By the pulling forward (as the direction that arrow indicated among Fig. 8) of leaning on 20 by shank, the screens groove 214 that the fin 224 at second junction surface 221 breaks away from first junction surface 211, therefore, shank can pivot with respect to seat board 10 by 20, and by by spring 40 ' elastic force, so that fin 224 is fastened on the screens groove 214 of diverse location, and be fixed on different sections.

But above-described only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, the variation and the replacement of every simple equivalent of doing according to the claim scope and the description of the utility model application all should still belong in the scope that the utility model patent contains.
