Abstract
The utility model relates to a screw nail capable of being wrenched by multiple manual tools. In the utility model, the first angle of a hexagon and the third angle of the hexagon are connected through an elliptical arc line; a fourth angle and a sixth angle are connected through the same elliptical arc line, and the third angle and a fifth angle are removed. The top of a screw nail head is provided with a hexagonal counterbore, and both sides of the screw nail head are extended outwards with inner counterbores for being suitable for the circular angles of a double offset ring inner hexagon spanner. The tools can be conveniently selected when the screw nail is screwed down or unscrewed. The utility model avoids the defect that inconvenience is generated because spanners and different dimensions are selected for the existing screw nails.
Description
The utility model belongs to the fastening piece category, but it relates to the moving screw of one kind of multiple instrument plates
Be connected with widely-used hex screw on the automotive industry, assemble and close fixing the use at engineering goods.Its specification is many, quantity is big and the branch of metric system and inch standard specification and size is arranged.Cause use to run into two kinds of troubles often, the first multi-formly need cooperate different spanners with the screw of specification when pulling, usually cause choose improper; It two is first range estimation screw sizes to be pulled and select identical size spanner for use, is difficult for once making an accurate selection of, and above-mentioned defective it brought loaded down with trivial details and inconvenient to the user.
But the purpose of this utility model is to propose the moving screws of one kind of multiple hand tools plates, and the screw end face make can insert in the counterbore of hexagonal and plum blossom inner hexagon spanner.Choose the loaded down with trivial details and inconvenient of spanner and overcome many bringing of existing screw sizes specification to the user.
The utility model is realized in the following way, the hexagon screw head is wherein connected with ellipse garden camber line shape between first jiao and the many third angles, the 4th jiao is connected with identical camber line with hexagonal, remove third angle and the 5th jiao, interior hexagon counterbore of screw end face system and each angle two side ends to extend out one can adapt to spanner inserts in the plum blossom fillet constitute quincunx in counterbore.
The advantage of this model utility is that this screw can be used size different within the specific limits back-up wrench and hexagon wrench, the plum blossom inner hexagon spanner pull screw it must select identical specification to cause when having avoided original screw to pull must repeatedly to choose the shortcoming that just can pull for use and, brought convenience to the user.
Accompanying drawing and drawing explanation:
Accompanying drawing 1, the utility model three-dimensional structure diagram
Accompanying drawing 2, the utility model is pulled schematic representation with different spanners
1 screw head, 2 open-end wrench, 3 ellipse garden camber line shapes, 4 hexagon counterbores, hexagonal counterbore, 6 fillets in 5 plum blossoms.
Below by embodiment in conjunction with the accompanying drawings the screw that can pull of one kind of multiple hand toolss of the utility model be described further: make profile between its first and third angle on original hexagon screw head 1, also make the camber line connection profile of same form and remove the 3rd and the 5th jiao between the 4th jiao and the hexagonal with 3 connections of ellipse garden camber line shape.The interior hexagonal counterbore 4 of hexagonal counterbore 6 in plum blossom of system on screw head 1 top, and make in its each both sides, wedge angle position and can adapt to the identical fillet 6 of plum blossom inner hexagon spanner circular arc profile, and make the gap of putting into the instrument fit by the instrument requirement, this screw head uses unclamp or screw the fixed spanner 2 of opening or inner hexagon spanner and plum blossom inner hexagon spanner pull schematic representation as shown in Figure 2.
Claims (1)
1, the screw that can pull of one kind of multiple hand toolss, it is characterized in that hexagon screw head (1), wherein connect with ellipse garden camber line shape (3) between first jiao and the third angle, the 4th jiao is connected with identical camber line with hexagonal, remove third angle and the 5th jiao, interior hexagonal counterbore of screw head end face system, and can adapt to the fillet (6) that spanner in the plum blossom inserts and constitute counterbore (5) in the plum blossom to extending out one in each angle two side ends.
