Abstract
The utility model discloses a center hole guiding head for a self-tapping screw, which consists of a paper tube with one conical end. The inner diameter of the paper tube is determined to be suitable for the self-tapping screw to be sleeved into the paper tube, and the length of the self-tapping screw is increased since the self-tapping screw is sleeved into the center hole guiding head of the self-tapping screw, so that an operator can manually control the root of the self-tapping screw, the tube can be easily inserted into a hole due to the conical end of the tube. The paper tube can be broken automatically, and thereby the self-tapping screw head is guided into the center hole and fastened with the same in the process of screwing the self-tapping screw or slightly pressing the root of the self-tapping screw, and meanwhile, tightness between the self-tapping screw and the center hole is enhanced.
Description
Technical field
The utility model belongs to fastening annex, more specifically to a kind of self-tapping type screw mesopore seeker.
Background technique
The hole separation distance of inserting when the mounting plate at self-tapping type screw root place and self-tapping type screw head is bigger, and the installation process mesopore is in invisible, the length of self-tapping type screw is not suitable for again holding under the situation that hand controls at self-tapping type screw root, then self-tapping type screw head mesopore is difficult to, and therefore provides a kind of self-tapping type screw mesopore seeker to have crucial meaning.
Summary of the invention
The purpose of this utility model provides a kind of self-tapping type screw mesopore seeker.
A kind of self-tapping type screw of the utility model mesopore seeker, it is made of the tapered papery body of an end.
The following beneficial effect of the utility model tool:
The utility model can guide self-tapping type screw head mesopore easily, thereby increases work efficiency, and has strengthened the tightness between self-tapping type screw and hole simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of self-tapping type screw of the utility model mesopore seeker.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of self-tapping type screw of the utility model mesopore seeker, it is made of the tapered papery body of an end.It is degree that the internal diameter of body is inserted in suitable self-tapping type screw, the self-tapping type screw is equivalent to increase self-tapping type screw length after being inserted in a kind of self-tapping type screw of the utility model mesopore seeker, so that the operator holds hand at self-tapping type screw root and controls, one end of body is because of tapered then very easy hand-hole, the operator is tightening the self-tapping type screw or is gently pressing in the self-tapping type screw root process, the papery body is broken voluntarily, thereby guiding self-tapping type screw head mesopore and fastening it, strengthened the tightness between self-tapping type screw and hole simultaneously.
Claims (1)
1. a self-tapping type screw mesopore seeker is characterized in that, it is made of the tapered papery body of an end.
