The utility model provides a detachable semicircle head screw, including nut and screw thread portion, be formed with the screw groove at the top of nut, the welding of the bottom integral type at the nut has the bulge, be formed with the kerve towards the nut in the bottom of screw groove, the diapire in kerve rotates and is connected with the kicking block, be formed with the movable groove in the bottom of bulge, be equipped with the internal screw rod with kicking block coaxial coupling in the movable inslot, wherein the thread bush is equipped with the lifter on the internal screw rod, and the inner wall laminating of lifter and movable groove, the diapire welding at the lifter has the seat that sinks, and the diapire welding of seat has the adhesion plate, be formed with the adaptation groove on the screw thread portion, adhesion plate and the diapire adaptation of adaptation groove.
As a preferred embodiment, an external thread is formed on the outer wall of the threaded portion; thereby facilitating the thread adaptation with other parts of the outside world.
As a preferred embodiment, a straight slot is formed on the top block; thereby being convenient for using the tiny cutter head to extend into the straight groove and rotate the top block.
As a preferred embodiment, the inner screw is vertically arranged in the movable groove and is rotationally connected with the protruding part; so that the inner screw can be stably operated.
As a preferred embodiment, an internal thread is formed in the fitting groove, and the outer wall of the protruding part is formed with a thread fitted with the internal thread; so that the protruding portion can be integrally connected with the threaded portion.
In summary, the technical effects and advantages of the present utility model are:
This detachable half round head screw passes the screw groove through using external small-size flat head screw and rotates the kicking block, makes it drive interior screw rod operation, makes the seat that sinks go up and down to appointed position to change the position of nut and screw portion, make this half round head screw detachable simultaneously, with the length of adjusting this half round head screw, make it be applicable to different scenes, improve application scope.
