Abstract
A tool head with a spiral drive part comprises a body. A groove is formed in the outer surface of the body and provided with a bottom wall, a color layer is arranged on the outer surface of the bottom wall to be used as identification, and the bottom wall does not protrude to the outer surface of the body. Due to the fact that the groove is formed in the outer surface of the body, a user can not easily touch the bottom wall of the groove when fetching the tool head, the color layer on the bottom wall of the groove can be prevented from dropping or being damaged and can be used for a long time, the drive part is of a long rod shape and provided with a spiral groove in a concave mode, the spiral groove is formed in the drive part in a surrounding mode along a long shaft of the drive part, then, the drive part has the drill-bit-shaped appearance, and therefore the tool head brings convenience for the user to work.
Description
Technical field
The utility model relates to a kind of instrument, specifically describes and relates to a kind of tool heads with the helical form drive division.
Background technology
As everyone knows, when general maintenance personal goes out to keep in repair, often because carrying too much instrument, needs make tool box quite heavy, on the other hand, the identification of the screwdriver head on tool heads easily is subject to external force factor with colour circle and produces wearing and tearing or peel off, and then cause this colour circle color to disappear, and lose the identification effect, be not easy to the operator and use.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model provides a kind of tool heads with the helical form drive division, because the outer surface of this tool heads body is provided with a chase, this chase has a diapire, and the outer surface of this diapire has a color layers, uses use as sign, this diapire does not protrude from the outer surface of this body, the diapire that is difficult for touching chase during user's fetching tool head, can prevent that the color layers of chase diapire from coming off or producing damage, and this color layers can be durable for a long time.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of tool heads with the helical form drive division, include body, chase, color layers, joint portion, drive division, external member, the outer surface of its body is provided with a chase, this chase has a diapire, the outer surface of this diapire has a color layers, use use as sign, this diapire does not protrude from the outer surface of this body, chase is located at joint portion, joint portion is concaved with a circular rabbet away from an end of drive division, circular rabbet is located on the outer surface of joint portion, circular rabbet has the outer surface of arc, circular rabbet is used for providing the nested connections of instrument such as tool bar, drive division is concaved with a helicla flute, helicla flute is located on drive division along the major axis of drive division, described chase has the first side wall and the second sidewall and diapire, the first side wall is parallel to the second sidewall, diapire is between the first side wall and the second sidewall, the girth at the arbitrary place of described diapire is all less than the girth of the first side wall outer peripheral edges and the girth of the second sidewall periphery edge, the distance of the first side wall and the second sidewall is less than the diameter of the outer peripheral edges at the arbitrary place of diapire, described diapire presents the circular-arc of indent, described color layers is the color paint vehicle.
The beneficial effects of the utility model are, a kind of tool heads with the helical form drive division, because the outer surface of this tool heads body is provided with a chase, this chase has a diapire, and the outer surface of this diapire has a color layers, uses use as sign, this diapire does not protrude from the outer surface of this body, the diapire that is difficult for touching chase during user's fetching tool head, can prevent that the color layers of chase diapire from coming off or producing damage, and this color layers can be durable for a long time.
