Description
[technical field]
The utility model relates to the technical field of fastening class part, the particularly technical field of screw class fastenings.
[background technique]
The kind of screw is a lot, conventional screw has fluting plain screw, interior hexagonal and interior hexagonal flower shape screw, cross recess plain screw, Cock screw, tapping screw, lifting bolt etc., existing screw, usually screw cap is only had, screw rod two-part, can not coordinate between screw with screw, screw is a kind of fastening piece conventional in daily life and industry, screw often can produce skidding because of screw cap surface smoother when hand Screw, flute profile screw may need the time that cutter head is stretched into notch when screwing with screw-driver, some notches are looser, skid when the little meeting of the degree of depth of groove makes screw-driver screw, have impact on efficiency and the quality of use, hand Screw screw may need the strength spent to become large when being screwed to screw rear end, such screw uses more inconvenient, and it is more difficult when absent-mindedness screw, removal efficiency is reduced.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of screw easy to use, and screw can be made conveniently to tighten and loose unloading, and structure is simple, and fastening effect is good, can be connected to each other between screw.
For achieving the above object, the utility model proposes a kind of screw easy to use, comprise screw cap, screw hole, screw mobile jib, threaded stem, tapering, described screw cap is hex shape, screw hole is provided with in screw cap, attachment screw mobile jib below screw cap, the face, upper hole of described screw hole and the upper-end surface of screw cap are at grade, the lower opening face of screw hole is in the inside of screw mobile jib, internal thread is provided with in screw hole, described screw mobile jib inside is provided with cross recess, the lower opening face of cross recessed upper groove surface and screw hole at grade, without screw thread on screw mobile jib, connecting thread bar below screw mobile jib, the outer surface of described threaded stem is provided with screw thread, the below of threaded stem is connected with tapering, described tapering is conical in shape.
As preferably, the center of described screw hole center, screw cap center, screw mobile jib center, cross recess center and threaded stem on the same line.
As preferably, the diameter of described screw hole is less than the diameter of screw thread mobile jib, and the diameter of screw hole equals cross recessed length, and the diameter of screw thread mobile jib equals the pitch diameter of external thread of threaded stem, and upper-end surface, tapering diameter is consistent with screw thread mobile jib diameter.
The beneficial effects of the utility model: the utility model, by screw hole being passed the inside of screw cap and screw mobile jib, is provided with screw thread in screw hole, is conducive to the cooperation between screw and screw, facilitate the use of screw; Be located at by cross recess in screw mobile jib, be provided with screw hole above cross recessed, the pine facilitating screw twists, and prevents from skidding during stubborn screw; Screw is provided with screw mobile jib, threaded stem and tapering, the pine that improve screw twists efficiency, and the using effect of screw is good.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
