Furthermore, a gap is formed between the lower end face of the arc-shaped through hole and the upper end face of the cross arm, and the height of the gap is smaller than that of the upper rotating shaft.

The invention has the beneficial effects that:

1. the rise card is accepted to rise module support upper end, internally mounted PCIE card, and rise module support provides the support for the installation of mount, and the PCIE support relies on the mount setting, and the buckle has the fastening state and opens and shuts the state

2. The buckle supports and leans on the PCIE support during the straining state, can improve the fastness of PCIE card installation, and when the buckle state of opening and shutting, be convenient for assemble or dismantle the PCIE card, it is more convenient to assemble or dismantle.

3. The profile is bent and is separated PCIE with upper end riser and lower extreme, and the arc through-hole has spacing and function of direction simultaneously, and the arc through-hole provides the mounted position for the last pivot of buckle, and square spacing hole has spacing function.

4. The effect that mount perpendicular to riser module support set up is guaranteeing the accurate installation of PCIE card, and the shaft hole on the fixed bolster sole provides the mounted position for the lower pivot of buckle, and the buckle rotation can be guaranteed in the shaft hole on arc through-hole and the sole.

5. The buckle body plays the effect of support, and the cross arm provides the mounted position for last pivot, sets up spacing subassembly on the connecting plate, and the connecting plate is supplemented with spacing subassembly function mutually, and spacing subassembly moves along with the up-and-down motion of connecting plate, and sunken effect is in order to form the gag lever post on the buckle body, and the effect of gag lever post is the height that the restriction connecting plate pushed down, and the effect of lower pivot is guaranteed that the buckle can rotate.

6. When the buckle is in a fastening state, the protrusion abuts against the PCIE support and is in point contact, so that the contact area is small, the pressure intensity is high, and the buckle is prevented from continuously rotating.

7. The connecting plate has elasticity and can be pressed downwards.

8. When the buckle will be in the fastening state, the connecting plate is pushed down, when square spacing platform on the connecting plate corresponds with the square spacing hole on the riser module support, the connecting plate is released, the square spacing platform is spacing with the buckle, and square spacing platform also has spacing effect, can prevent effectively that buckle and riser module support front end edge from producing and interfering.

9. The lower rotating shaft is arranged in the shaft hole of the foot plate of the fixing frame, the foot plate provides a place for mounting the lower rotating shaft, and the rotation of the axis of the lower rotating shaft as a center under the buckle can be ensured.

10. The clearance between terminal surface and the cross arm up end is greater than the height of last pivot under the arc through-hole, during the installation buckle, installs the pivot earlier, makes the pivot run through the arc through-hole completely to guarantee that the up end of cross arm and the lower terminal surface laminating of arc through-hole, the pivot is down in the installation of being convenient for, after the pivot is installed in the axle hole under will, releases the buckle, the pivot card is in the arc through-hole on going up of buckle, the pivot card is in the axle hole down.
