Embodiment

Please refer to Fig. 1 to Fig. 3, stationary installation of the present invention is used for a movable module 10 is fixed in the cabinet 20.This stationary installation comprises a fastener 30 and an operating parts 40.Movable module 10 can be server module or memory module.

This cabinet 20 comprises the two side 22 that a diapire 21 reaches perpendicular to diapire 21.Each sidewall 22 is offered two parallel draw-in grooves 221.

Movable module 10 comprises a base plate 11, vertically extends from the biside plate 12 of base plate 11 both sides and vertically extend from base plate 11 1 ends and connect the end plate 13 of biside plate 12.End plate 13 adjacent side plates 12 places offer one and wear groove 131.Side plate 12 is offered contiguous perforation 121 places, inboard that two parallel perforation 121, two fixed legs 123 are convexly set in side plate 12.Side plate 12 inwardly is convexly equipped with a boss 125 respectively in the both sides up and down of two fixed legs 123, and each boss 125 along continuous straight runs is offered two fixed orifices 126.Side plate 12 contiguous end plates 13 places inwardly are convexly equipped with a pair of flexible location division 128.

Fastener 30 generally is flexible lamellar body, and it comprises a stator 31 and the shell fragment 33 that is bent to form from an end of stator 31, and the end of shell fragment 33 is convexly equipped with the clamping part 331 of two wedge shapes.Stator 31 is offered two fixed orifices 311.

Operating parts 40 general piece shapes, it comprises a main part 41.Main part 41 is offered the chute 411 of two levels.One end of main part 41 is provided with the handle portion 45 of a ring-type.The other end of main part 41 is provided with one and presses card division 43.Main part 41 contiguous handle portion 45 places offer two pairs of pilot holes 46 respectively.Handle portion 45 is fastened the frenulum 47 of establishing a flexibility.

During assembling, fastener 30 is fixed in fixed leg 123 by two fixed orifices 311.Two clamping parts 331 are aimed at two perforation 121 respectively.The two pairs of fixtures 50 pass respectively and are locked in fixed orifice 126 behind the chute 411 of operating parts 40 operating parts 40 Slide Groups are located on the boss 125, and make the operating parts 40 can be along side plate 12 inner slide.The handle portion 45 extended grooves 131 of wearing of operating parts 40.Fixture 50 can be screw or rivet.

When installation activity module 10 arrives in the cabinet 20, movable module 10 is pushed cabinet 20, draw-in groove 221 is aimed at perforation 121 respectively.Operating parts 40 is pushed inwards, the shell fragment 33 that the pressure card division 43 of operating parts 40 compresses fastener 30 makes shell fragment 33 to side plate 12 direction generation elastic deformations, pass perforation respectively until two clamping parts 331 and snap in the draw-in groove 221 after 121, and then movable module 10 is snapped in the cabinet 20 prevents from.Two location divisions 128 snap in wherein in a pair of pilot hole 46 operating parts 40 being positioned of contiguous handle portion 45.

During dismounting activity module 10, be pulled outwardly out operating parts 40 in cabinet 20, the pressure card division 43 of operating parts 40 breaks away from shell fragment 33 presses card, and shell fragment 33 resets so that two clamping parts 331 are deviate from draw-in groove 221 respectively, and then movable module 10 can be extracted out.Two location divisions 128 snap in wherein in a pair of pilot hole 46 operating parts 40 is positioned away from handle portion 45.
