As a further solution of the present invention: the cross-section of the inner hexagonal thread inner concave arc top nail is set to be inner concave arc shape or outer convex circle or plane or inner concave triangle.

As a further solution of the utility model: the slider nut moves up and down in the through hole of the body and is relatively fixed to the body through a positioning round pin.

As a further solution of the present utility model: the positioning round pin is provided with a spring to provide a pop-up function.

As a further solution of the utility model: the slider nut is provided with a slot for connecting workpieces, and the slot is a whole-circle slope type or a square groove type or an inner concave reverse cone type or an inner concave spherical type.

Compared with the prior art, the beneficial effect of the utility model is: the utility model has a simple structure and a reasonable design. The body is designed with a long straight section which can be clamped on a three-jaw turntable or flat-nose pliers and other workbenches. It can be connected and locked with the workpiece. The workpiece is inserted into the through hole of the body. Align the positioning square pin to fix the direction to be oriented. The positioning round pin is used to lock the locking slider nut. The spring can make the positioning round pin pop out quickly. The compression threaded sleeve can make the positioning round pin move in and out quickly through the thread, precisely tighten and lock the workpiece, and finally use the inner hexagon thread concave arc top nail to assist in locking the workpiece to prevent rotation, so as to achieve simple and fast clamping and precise orientation Purpose, it has the characteristics of simple operation, precise and stable positioning, and high equipment utilization rate, which greatly reduces the unqualified rate of workpieces and improves production efficiency and production quality.
