Screw rod when in use, is screwed in nut, meanwhile external screw thread quilt by the way of rotation by this setting
Screw in outside female thread, increased one group of screw thread outside original screw, increased the intensity of screw, so that screw is born bigger
Pulling force.
Of the present utility model it is further arranged to: securing member includes directly rod and a pitman, directly rod is located at screw
On head, directly rod is fixedly connected with screw terminal, and directly the lower end of rod is provided with two annulus interlocking, and an annulus is fixing with directly rod even
Connect, pitman is located at the lower end of directly rod, pitman is fixedly connected with another annulus, secure fit part is a groove, groove
Positioned at the plane of the bottom of screw rod, groove is adapted to pitman.
When in use, because two annulus interlock, therefore pitman is rotatable, and user rotatably connects for this setting
Take over the baton and insert it in groove, because directly excellent one end is fixed with nut, pitman passes through to fix in groove, makes two annulus relatively
Fixing, thus realize directly rod fixing with pitman, strengthening screw, enabling screw to bear bigger pulling force.
Of the present utility model it is further arranged to: screw terminal is provided with the auxiliary member for assisting screw to screw in, auxiliary member
For two casting lug thereons, respectively positioned at the both sides of screw terminal, casting lug thereon is fixedly connected casting lug thereon with screw terminal.
When in use, user can be taken and hold the casting lug thereon of both sides for this setting, make casting lug thereon become user by spiral shell
The impetus that silk screws in, thus more easily complete the fixation of screw.
Brief description
