The use method of the semi-automatic scribing compass comprises the following steps: the marking handle 10 is held and downward force is applied, the rotating shaft 3 enters the marking cavity 1 through manual downward force application, the pressure spring 8 is compressed, the spiral guide rail 2 moves upwards, and the guide ball 12 drives the spiral guide rail 2 to rotate along with the guide ball 12, so that the spiral guide rail 2 moves upwards and rotates along with the rotation. The groove of the rotating shaft 3 is connected with the spiral guide rail 2, when the spiral guide rail 2 rotates, the rotating shaft 3 also rotates at the same time, and the movable leg 18 of the compass is driven to draw a circle around the specified leg 19 of the circle. As a downward force is applied in operation, the rotating shaft 3 is retracted back into the scribing cavity 1. After the circle is drawn, when the hand is released, the spiral guide rail 2 rotates back to the original position again because the potential energy stored by the pressure spring 8 is released upwards.
The rotating shaft fixing sleeve 4 is used for limiting the rotating shaft 3, so that the rotating shaft 3 cannot pop out of the scribing compass body. The upper bearing cover 7 contracts and rebounds along with the pressure spring 8, and does not rotate.

The guide ball fixing sleeve 11 is used for fixing the guide ball 12, so that the guide ball 12 and the scribing compass body are relatively static and are kept still. The marking gauge handle 10 and the spring fixing seat 9 are two base points of the pressure spring 8, so that the pressure spring 8 is compressed or rebounded.
The hard alloy needle 14 at the lower end of the semi-automatic marking gauge is used for centering the circle center, the hard alloy needle 14 rotates automatically, and the marking needle 1614 at the right side rotates to make a circle. The cross bar 15 is used for adjusting the size of the radius of the drawn circle, the drawing range is between 30 and 200, and the radius can be continuously enlarged when necessary. The cross rod 15 and the hard alloy needle 14 are locked with the cross rod fixing sleeve 13 through nuts. The length of the cross rod 15 can be freely adjusted after the nut is loosened, and after the radius is determined, the cross rod is locked to adjust the radius of the drawn circle. The scriber 16 is a working end and is used for scribing and forming and is fixedly connected with the cross rod 15. And the scriber fixing sleeve 21 internally contains a spring 20, and can be used for scribing a circle on a steel plate or a cylindrical surface with an uneven surface.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and the present invention is not limited to the embodiments of the present invention, and the modifications and variations of the present invention can be easily made by those skilled in the art according to the main concept and spirit of the present invention.
