As further improvement of the utility model, the position that this axle is inserted into this pipe spring is provided with a plurality of oil storage annular grooves.
As further improvement of the utility model, this axle end and pipe reed pipe mouth are respectively equipped with ring-type chamfering and the ring-type bevel edge of being convenient to assemble.
As further improvement of the utility model, this bolster is provided with a plurality of these pipe springs side by side, open slot on these a plurality of pipe springs arranges along the same axis, and the standstill face on these a plurality of pipe springs arranges along the same axis, and this axle corresponding end stretches into and is tight with in these a plurality of pipe springs.
As further improvement of the utility model, this axle end and respective tube reed pipe mouth are respectively equipped with ring-type chamfering and the ring-type bevel edge of being convenient to assemble.
As further improvement of the utility model, the position that this axle is inserted into these a plurality of pipe springs is provided with a plurality of oil storage annular grooves.
Useful technique effect of the present utility model is: this axle one end connects liquid crystal screen, the other end stretches into and is tight with in the pipe spring on this bolster, this pipe spring is formed by rigid and is circular, this pipe spring radially is provided with open slot, this axle sidepiece and this pipe spring inside portion are respectively equipped with locating surface and the standstill face of being convenient to rotational positioning vertically, this open slot is symmetrical vertical along pipe spring end section direction with the standstill face, this axle is opened or the stressed dilatating and deformable of annulus when closed, be subjected to twisting force, can be in positioned at arbitrary angles between the liquid crystal screen that connects this axle and the motherboard that is connected bolster, locating surface on this axle coincides this liquid crystal screen and host computer plate closing with the standstill face of pipe spring inside portion.

Embodiment
One of embodiment in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, below is described in detail:
A kind of improvement structure of computer-positioning spindle, be installed between computer motherboard and the liquid crystal screen, comprise the axle 1 that connects liquid crystal screen and the bolster 2 that is connected computer motherboard, this bolster is provided with one and is formed and be circular pipe spring 21 by rigid, this pipe spring is provided with open slot 211 vertically, this axle one end connects liquid crystal screen, and the other end stretches into and be tight with in this pipe spring 21, this axle sidepiece and this pipe spring inside portion are respectively equipped with locating surface 11 and the standstill face 212 of being convenient to rotational positioning vertically, and this open slot 211 is symmetrical vertical along pipe spring end section direction with standstill face 212.
The position that this axle 1 is inserted into this pipe spring 21 is provided with a plurality of oil storage annular grooves 12, be conducive to the axle rotational positioning, this axle 1 end and pipe spring 21 mouths of pipe are respectively equipped with ring-type chamfering 13 and ring-type bevel edge 213, be convenient to assemble between axle and the pipe spring, open slot 211 on this pipe spring is symmetrical vertical with standstill face 212, is conducive to like this open closed torsion equilibrium between computer motherboard and the liquid crystal screen.
Two of embodiment, on one of embodiment basis, this bolster is provided with a plurality of these pipe springs side by side, and the open slot 211 on these a plurality of pipe springs arranges along the same axis, standstill face 212 on these a plurality of pipe springs arranges along the same axis, and this axle corresponding end stretches into and is tight with in these a plurality of pipe springs 21.
