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., 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 Quick fastening screw, and screw can be made conveniently to tighten and loose unloading, and structure is simple, and fastening effect is good.
For achieving the above object, the utility model proposes a kind of Quick fastening screw, comprise screw cap, screw mobile jib, threaded stem, tapering, described screw cap is cylindrical shape, the side of screw cap is provided with the first hole, the below of screw cap is screw mobile jib, described screw mobile jib outer surface is without screw thread, in succession threaded stem in the lower end of screw mobile jib, there is outside thread on described threaded stem surface, the second hole is provided with in threaded stem, second hole is provided with internal thread, the lower end of threaded stem is connected with tapering, in conical in shape bottom described tapering, tapering is provided with thread spindle, thread spindle surface is provided with outside thread.
As preferably, the side of screw cap is run through in described first hole, and the center of screw cap is consistent with the center in the first hole, and threaded stem inside is not run through in the second hole, and the center in the second hole and the center of threaded stem are on the same line.
As preferably, the diameter of described screw mobile jib is the same with the pitch diameter of external thread size of threaded stem.
As preferably, described tapering and threaded stem removably connect, and the outside thread of thread spindle and the internal thread in the second hole cooperatively interact, and thread spindle diameter is less than the diameter in the second hole.
As preferably, described thread spindle is exposed the same with the depth size in hole in the height size of tapering exterior portion.
The beneficial effects of the utility model: the utility model, by screw cap side is provided with the first hole, can tighten screw by instrument, facilitates the use of round head bolt, avoid skidding when thread; Be threaded threaded stem and threadless screw mobile jib by screw rod part, facilitate tightening and relaxing of screw; Be provided with screw thread by thread spindle and the second hole, achieve the function that tapering and threaded stem removably connect, tapering apex area is little, thus not only laborsaving but also quick when making stubborn screw.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
