Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

A die guiding tool comprises a die wrench 2, a pressing plate 3 and a limiting mechanism.

As shown in fig. 1 and 2, the die wrench 2 includes a cylindrical body, a handle 22 horizontally disposed is installed on a side of the body, preferably, the handle 22 is symmetrically disposed on two sides of the die wrench 2 and coaxially disposed, a sunken cylindrical hole is formed in the middle of the upper surface of the die wrench 2 to serve as a die slot body, the die slot body is used for placing a die 100, a guide hole 21 penetrating through the die wrench 2 is formed in the bottom of the die slot body, an axis of the guide hole 21 is perpendicular to the bottom surface of the die slot body, when the die 100 is placed in the die slot body, a threaded hole 101 in the die 100 corresponds to the guide hole, and the diameter of the guide hole is the same as that of a threaded hole 101 of the die 100.

As shown in fig. 1 and 2, when the die 100 is placed in the die slot, the die 100 is pressed in the die slot through the pressing plate 3, and the threaded hole 101 of the die 100 is not shielded, specifically, the pressing plate 3 covers the top of the die wrench 2, the plate body of the pressing plate 3 is connected with the top surface of the die wrench 2 through the bolt 31, the middle part of the pressing plate 3 is provided with a through hole, and the diameter of the through hole on the pressing plate is larger than the inner diameter of the die 100 and smaller than the outer diameter of the die 100; in one embodiment, the pressing plate 3 is an annular plate, and the annular portion of the pressing plate 3 is fixed to the top of the die wrench 2, it should be understood that the pressing plate 3 is not limited to the above structure, and in some embodiments, the pressing plate 3 may be a strip-shaped plate body pressed on both sides of the threaded hole 101 of the die 100, or a square plate with an opening in the middle.
