Abstract
The utility model provides a screw, includes screw rod and screw head, and the screw head be circular, and screw is overhead to be equipped with axial extension, and the extension is cylindrical, and the diameter of extension is less than the first diameter of screw, is equipped with the cross recess on the extension, and the cross recess is equipped with the through -hole that runs through run through the screw head by extension one end in on the extension periphery. The beneficial effects of the utility model are that rational in infrastructure simple, the cross recess degree of depth is great, can avoid damage, can screw up through other modes moreover, and avoid extravagant.
Description
Technical field
This utility model belong to mechanical part field and in particular to be a kind of screw.
Background technology
Screw is one of the most frequently used secure component, all has in numerous areas such as mechanical engineering, electrical equipment, medical apparatus and instruments
Applied.Screw common in the art is by the metal spiral shell of a head of screw with groove and a threaded cylinder or cone
Nail rod forms, and head of screw and shank of screw are usually wholely set.It is inserted in groove using screwdriver and turns head of screw, drive spiral shell
The rotation of nail rod.The groove opening up on existing head of screw is generally cross recess or flat recess, and groove only opens up one, so
Head of screw on groove in dismounting or installation it may occur that due to groove damage, and cannot be carried out dismantle and install situation.
Utility model content
For solving above-mentioned technical problem, this utility model provides one kind to be prevented from damaging, by twisting in several ways
Tight screw.
For achieving the above object, the technical solution adopted in the utility model is, a kind of screw, including screw rod and head of screw,
Head of screw is circle, and head of screw is provided with axial extension, and extension is cylinder, and the diameter of extension is less than head of screw
Diameter, extension is provided with cross recess, and cross recess extends through in head of screw by extension one end, and extension periphery is provided with and passes through
The through hole worn.
As preferred version of the present utility model, the extended height of extension is 2 times of the thickness of head of screw.
As preferred version of the present utility model, the 1/2 of the height of a diameter of extension of the through hole on extension.
As preferred version of the present utility model, head of screw and screw rod are all made using corundum, and head of screw and screw rod are integrally
Molding.
The beneficial effects of the utility model are: rational in infrastructure simple, cross groove depth is larger, are prevented from damaging, and
Can be tightened by other means, it is to avoid waste.
