Abstract

The utility model discloses an anti-skew self-tapping screw cape, which is characterized by comprising a screwdriver head rod and a sleeve, wherein the sleeve is a hollow cylinder which is through from front to back, the size of an inner hole at the upper end of the sleeve is matched with the outer diameter of the screwdriver head rod, the inner wall at the upper end is provided with an opening for installing a spherical alloy steel ball, and the spherical alloy steel ball is movably matched with the sleeve; the utility model discloses simple structure makes the screw along telescopic axial displacement through setting up the sleeve, and at the during operation, telescopic lower extreme plane supports in target object's surface, and it is rotatory to drive the screw when criticizing the bull stick and rotate, bores into the object inside, and this process sleeve keeps perpendicular with target object, avoids appearing the problem that the screw slope bored into, and the activity of spherical alloy steel ball sets up, not only nimble lifting efficiency, and the dismouting of being convenient for is changed.

Description

Anti-tilting self-tapping screw cape

Technical Field

The present invention relates to a fastener, and more particularly to a self-tapping screw related tool.

Background

A screwdriver, also known as a screwdriver, is a tool used to turn a screw to force it into position, usually comprising a shank and a handle, the tip of the shank carrying a head that fits into the screw and can be inserted into a coupling groove or recess of the screw, the most common of which are mainly crossed (plus) and straight (minus).

The conventional tapping screw generally includes a threaded shaft body having a head formed at one end thereof, and a coupling groove formed at an upper end surface of the head. When the screw needs to be disassembled or fastened, the screw can be driven to rotate only by adopting a corresponding wrench. When the self-tapping screw is used, the problem that the screw is not drilled into the surface of a target object or a wall body or the material is solved, and the screw is difficult to correct once the angle is not correct for the first time, so that the self-tapping screw cannot be completely fixed.

SUMMERY OF THE UTILITY MODEL

To the problem that exists, the utility model discloses a prevent askew self tapping screw and drape over one's shoulders, its mode through possessing the subassembly of usefulness of correcting solves the self tapping screw and often installs improper problem when using.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a prevent askew self tapping screw and drape over one's shoulders which characterized in that, includes criticize first pole and sleeve, the sleeve is the hollow cylinder penetrating from beginning to end, telescopic upper end hole size and criticize the external diameter phase-match of first pole, and the upper end inner wall is provided with the opening for install spherical alloy steel ball, spherical alloy steel ball and sleeve clearance fit.

In a further arrangement of the above scheme, the batch head rod is provided with a strong magnet or a strong magnet is embedded in the batch head rod.

As a further arrangement of the scheme, the sleeve is further in threaded connection with a steel ball fixing ring for mounting the spherical alloy steel ball.

As a further arrangement of the scheme, the middle part of the screwdriver head rod is provided with a sliding groove for the movement of the spherical alloy steel balls.

Has the advantages that:

the utility model discloses simple structure makes the screw along telescopic axial displacement through setting up the sleeve, and at the during operation, telescopic lower extreme plane supports in target object's surface, and it is rotatory to drive the screw when criticizing the bull stick and rotate, bores into the object inside, and this process sleeve keeps perpendicular with target object, avoids appearing the problem that the screw slope bored into, and the activity of spherical alloy steel ball sets up, not only nimble lifting efficiency, and the dismouting of being convenient for is changed.

Detailed Description

The following detailed description describes embodiments of the invention, examples of which are intended to explain the invention, and the terms "upper", "lower", "top", "bottom", and the like in the embodiments indicate positional or orientational relationships and are merely for convenience in describing the invention and to simplify the description, and do not indicate or imply that the components or elements so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be construed as limiting the invention.

As shown in fig. 1-3, the utility model provides a prevent askew self tapping screw and drape over one's shoulders, a serial communication port, including criticizing first pole 1 and sleeve 2, sleeve 2 is the penetrating hollow cylinder in front and back, the upper end hole size of sleeve 2 and the external diameter phase-match of criticizing first pole 1, and the upper end inner wall is provided with opening 3 for install spherical alloy steel ball 21, spherical alloy steel ball 21 and sleeve 2 clearance fit.

In a further arrangement of the above arrangement, the bit rod 1 is provided with a strong magnet or a strong magnet fitted thereto.

As a further arrangement of the above scheme, the sleeve 2 is further in threaded connection with a steel ball fixing ring 23 for mounting the spherical alloy steel ball 21.

As a further arrangement of the scheme, the middle part of the batch head rod 1 is provided with a chute 11 for the movement of the spherical alloy steel balls 21.

Example (b): the utility model discloses a criticize first pole 1 and sleeve 2 split that can be very convenient, can install according to the demand during use or not, if need install sleeve 2, as long as aim at sleeve 2's upper end and criticize first pole 1's afterbody, impel gently hard, spherical alloy steel ball 21 is in the spout 11 at middle part of 1 thick part back gomphosis of first pole afterbody through criticizing, spherical alloy steel ball 21 with criticizing first pole 1 interference fit, need exert hard gently when having guaranteed sleeve 2 installation, spherical alloy steel ball 21 impels along the inclined plane of criticizing first pole 1 and just can fall into spout 11 interior completion assembly, and draw outward gently during the use again and be difficult to drop.

During the use, adsorb self-tapping screw at criticizing first pole 1 afterbody, slide down sleeve 2 along criticizing first pole 1 again and surpass the self-tapping screw point and put, aim at the target object position with the self-tapping screw point again, support sleeve 2 on the object surface, let sleeve 2's plane and object surface offset, hold up sleeve 2 a little, criticize first pole 1 and rotate and can be with behind the perpendicular income object of self-tapping screw.
