As depicted in figs. 1 and 2, Fig. 1 is the stereogram of the locking screw fixed mechanism of locking described in the utility model；Figure
2 be the sectional view of fixture described in the utility model.A kind of screw fixed mechanism that locking is locking, including fixed seat 1, quilt
Fixing piece 2 and locking screw 3；The fixed seat 1 offers the threaded hole coordinated with the locking screw 3, the fixture 2
Including a fixed column 21, the fixed column 21 is provided in the axial direction with through-hole of the diameter more than the head of screw of the locking screw 3,
One end is screw insertion end, and the other end is screw fixing end, and the opening diameter of screw insertion end is more than the spiral shell of the locking screw
The opening diameter of ailhead, screw fixing end is more than the head of screw that locking screw is less than locking screw 3；Two couple of the fixed column 21
Side is claimed to offer the straight slot led to inside fixed column, respectively extending width from screw insertion end in two straight slot is less than described lead to
The elastic locking rod 22 of slot, elasticity 22 end of locking rod are detached with the screw fixing end of fixed column, described two elastic lockings
The radial distance of bar 22 is gradually reduced along screw direction of insertion, and end distance is less than the head of screw 3 of locking screw, and offers
Head of screw screens.
Specifically, as shown in figure 3, Fig. 3 is the enlarged diagram of A in the utility model Fig. 2.Described two elastic locking rods 22
The middle part relative axis direction of opposite flank is inclined-plane, and the angle of the inclined-plane and axis direction is guide angle a, 0 ° of a≤90 ° ＜.
The setting structure plays screw into fashionable guiding role.
The head of screw screens is the groove that described two elastic 22 end symmetricals of locking rod open up, and the groove includes and axis
The spiral shell is clamped in the first parallel face 221 of line and vertical with the first face or obtuse-angulate second face 222, described two first faces 221
Screw top surface is supported in ailhead both sides, described two second faces 222.
Second face and axis direction angle are angle of lock b, 60 ° of b≤90 ° ＜.If angle of lock b angles are too small, locking
It can be easy to exit from the through-hole of fixed column 21 after screw loosening, therefore the angle of angle of lock b is arranged at 60 ° to 90 ° more
Properly, and lockup capacity is positively correlated with angular dimension in the range.
Preferably, guide angle a ＜ angle of lock b, the setting relatively can smoothly enter into through-hole when screw being made to install, and while exiting needs
Large force can just exit through-hole.
The screw fixing end of the fixed column 21 is additionally provided with the recess 211 coordinated with the screw head shapes of locking screw 3,
When locking screw 3 enters screw fixing end, which is bonded completely with the side of head of screw, increases screw and fixation
