Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 6 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of locking machine screw, including screw body
1, screw body plays the fixed effect that is threadedly coupled, and the middle part of the screw body is run through vertically is equipped with through hole 2, the through hole
Middle part of sliding channel be equipped with internal thread, the upper end of the through hole is equipped with groove 3, and the madial wall of the groove is equipped with telescopic chute 4,
The bottom of the telescopic chute is fixedly connected with one end of retaining spring 5, and adjustable spring can be movable in telescopic chute, the positioning bullet
The other end of spring is equipped with Telescopic positioning lever 6, runs through in the through hole and is threaded with positioning screw 7, wherein when positioning screw
When position is located at the downside of Telescopic positioning lever, the elastic force of retaining spring makes Telescopic positioning lever stretch out telescopic chute, and Telescopic positioning lever makes
Positioning screw is remained unchanged with respect to the position of screw body, and the upper end of the positioning screw is equipped with hexagonal inside groove 8, hexagonal inside groove side
Just are equipped with by top cap 9, is arranged with the downside of the screw body for the torquing operations of positioning screw, the lower end of the positioning screw
Locating piece 10, when the horizontal distance of locating piece is more than the diameter of screw body lower part, locating piece is contacted with the inner wall of threaded hole
Clamping, makes screw body no longer and is loosened because of vibrations, positioning screw is outwards screwed, is made in top cap retraction through hole, and at this time two
A locating piece combines, both relative distance diminishes, and less than the diameter of screw body lower part, then screw body is screwed into screw thread
Hole, then positioning screw is screwed, top cap is stretched out through hole, top cap is contacted with two locating pieces at this time, and the side of its trapezoidal shape is with determining
The contact of incline plane of position block extrudes it, locating piece water is relatively distant from movement, slip is equipped with the upper surface of the locating piece
