Detailed Description

Various embodiments of the present invention will be described with reference to the accompanying drawings. In the specification and drawings, elements having similar structures or functions will be denoted by the same reference numerals. It is to be understood that the drawings are designed solely for the purposes of illustration and description and not as a definition of the limits of the invention. The dimensions shown in the figures are for clarity of description only and are not intended to be limiting, nor are they intended to be exhaustive or to limit the scope of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1-2, a screw column with a positioning function includes a screw column body 1, two positioning grooves 11 are disposed on an end surface of the screw column body 1, the two positioning grooves 11 are respectively distributed along a radial direction of the screw column body 1, and a central line of the two positioning grooves 11 forms an included angle. The length, width and height of the positioning slot 11 are determined according to actual use requirements.

The included angle is typically between 100 deg. and 150 deg., and in this embodiment the center lines of the two positioning slots 11 form an included angle of, in particular, 120 deg. (as shown in fig. 1).

Since the stud also needs to be engaged with the screw, a space for engaging with the screw is usually left in the center of the end face of the stud, and therefore the length of the positioning slot 11 is usually smaller than the radius of one end face of the stud body 1.

Further, the positioning groove 11 is disposed along the outer edge of the end surface of the screw column, and the positioning groove 11 has two openings, one of the two openings is located on an end surface of the screw column body 1, and the other opening is located on the side wall of the screw column body 1.
