Embodiment one, combine fig. 1-10, a fastening device for computer chassis jack, including jack 2 and plug 3 cooperating with jack 2 opened on chassis 1, the said jack 2 is a rectangular groove, what is shown in the figure is various cooperating relations when jack 2 is up, in the practical application, data transmission line and power cord are inserted in the rear of chassis 1, so the positional relation shown in the figure does not represent that the device must be that jack 2 is set up upwards, but describe in detail in connection with this positional relation, the jack 2 is equipped with a column pole cooperating with plug 3, both cooperate to make both carry on the transmission of electric power or data, jack 2 is a rectangular groove and is also often used in the prior art, characterized in that, there are cavities 4 between the lateral side wall of the said plug 3 and the corresponding side wall of jack 2, plug 3 and jack 2 are vertically sliding fit, in this case, the two side walls of the plug 3 in the longitudinal direction are in clearance sliding fit with the two side walls in the longitudinal direction in the insertion hole 2, the transverse side walls are provided with a cavity 4 therebetween, the size of the cavity 4 left on the two sides is the same, the insertion hole 2 is provided with accommodating grooves 5 on the two opposite inner side walls in the length direction, namely, the accommodating grooves 5 are arranged on the two side walls in the transverse direction of the insertion hole 2, the position of the accommodating grooves is determined by the parts matched with the accommodating grooves, a trapezoidal wedge block 6 with an upward inclined surface is connected in the accommodating groove 5 in the length direction in a sliding manner, a return spring 7 is connected between the wedge block and the bottom wall of the accommodating groove 5, the trapezoidal wedge block 6 is made of light plastic, because the trapezoidal wedge block 6 does not deform the return spring 7 due to dead weight when the position in the drawing, but when the insertion hole 2 is arranged towards the rear, the return spring 7 is prevented from deforming due, therefore, the material of the trapezoidal wedge block 6 needs to be selected to be lighter as much as possible;

the plug 3 is arranged on the horizontal two end faces of the bottom in the jack 2 and is longitudinally connected with a curved surface rod 8 arranged in the cavity 4, the lower end of the curved surface rod 8 is a curved surface, the upper end of the curved surface rod is provided with a chute 9 which inclines downwards towards the center direction of the two curved surface rods 8, the curved surface of the lower end of the curved surface rod 8 is in parallel and level transition with the bottom end of the plug 3, the arc bending direction of the curved surface meets the requirement that the curved surface rod 8 moves downwards, the curved surface of the lower end of the curved surface rod 8 is firstly in contact fit with the inclined surface at the upper end of the trapezoidal wedge 6, the curved surface can push the trapezoidal wedge 6 to move backwards in the accommodating groove 5 until the curved surface rod 8 crosses the trapezoidal wedge 6, a right-angled triangular limiting rod 10 which is longitudinally connected on the side wall of the plug 3 and is arranged with the inclined surface downwards is arranged above the curved surface rod 8, one right-angled edge

movement, after the curved rod 8 passes through the position of the trapezoidal wedge block 6, at this time, because the plane of the lower end of the trapezoidal wedge 6 is matched with the upper end of the curved rod 8, the plug 3 cannot be pulled out of the jack 2 under the limitation of the trapezoidal wedge 6, when the jack 2 is arranged backwards, the plug 3 is kept at the current position under the effect of no external force, but when the jack 2 is arranged upwards, the plug 3 may move downwards due to the self-weight, at this time, we only need to select the spring with larger stiffness coefficient of the return spring 7 when selecting the return spring 7, so that under the condition of self-weight of the plug 3, under the effect of the return spring 7, the trapezoidal wedge 6 acted by the return spring 7 limits the downward movement of the plug 3, so that the plug cannot move downwards continuously under the effect of no external force, at this time, the fastening effect is excellent, when the plug 3 needs to be pulled out, the plug 3 is pushed downwards to the limit position, at this time, refer to the attached drawings, after contacting the movable rod, the
