Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, a kind of embodiment provided by the utility model: a kind of fitting and high fixed screw, including
Screw terminal 1, screw terminal 1 is in cylindrical structure, and the middle position of 1 bottom of screw terminal is fixed with screw rod 2, screw rod 2
Outside is provided with screw thread threading 8, and card slot 3 is arranged in the top of screw terminal 1, and the outside of screw terminal 1 is fixed with outer sleeve 4, outer sleeve
4 inside is socketed with inner sleeve 6, and the bottom of screw terminal 1 is equipped with spring 7, and the lower section of screw terminal 1 is connected with interior by spring 7
Sleeve 6, screw rod 2 are located at the outside of inner sleeve 6, and the lower section in 6 outside of inner sleeve is provided with gear tooth line 10, outer sleeve 4 and interior
The junction of sleeve 6 is provided with annulus 11, and outer sleeve 4 is plastic material, and material is light and handy, is convenient for turn, and inner sleeve 6 is steel material
Matter can preferably protect screw rod 2, and annulus 11 is curve concave toroidal design, convenient to fit with arc hole location, with right
There is the product of cambered surface to be fixed, reinforces fixed effect.
In the present embodiment: by pressing inner sleeve 6, making 6 compressed spring 7 of inner sleeve, inner sleeve 6 is protruded into outer sleeve 4
Inside so that screw rod 2 is exposed carry out that the fastening effect of screw can be reinforced using the screw thread threading 8 in 2 outside of, screw rod,
