Abstract
The utility model provides a screw convenient to mount. The screw comprises a first stud, a screw head arranged on the first stud, and screwing teeth arranged on the top of the screw head. Screw holes are formed in the two sides of the screw head and provided with screwing heads. The screw has the advantages of being convenient to mount and dismount, space saving, sliding resistant, reasonable in design, simple in structure, simple and convenient to manufacture and the like.
Description
Technical field
The utility model relates to mechanical engineering technical field, is specifically related to install screw easily.
Background technique
Screw is to utilize the inclined-plane circular rotating of physics and physics and the mathematical principle of frictional force, the instrument of fastening implements parts by easy stages, it is industrial necessity indispensable in daily life, application is very extensive, little of the wrist-watch glasses, large to the train steamer, space shuttle, screw is the common invention in people's productive life over the past thousands of years, according to application, it is the mankind's first invention, screw is mainly by screw-driver or crosshead precession implements, the shape that screws tooth depending on the screw top, existing screw material differs, the screw that material is softer or in the situation that implements hardness is larger, sliding tooth easily occurs in screwing operation, multi-pass operation easily will screw tooth and polish, thereby cause screw to cancel, wasted material, and there is no corresponding solution in prior art.
Summary of the invention
Technical problem to be solved in the utility model is to provide installs screw easily, reasonable in design, simple in structure, manufacture easyly, can make screw means by twisting head after the screw means tooth screws operation failure, can avoid screw to cancel, save material, make screw install more convenient simultaneously, and, twist the dismounting facility of head, the space-saving good nature that can keep screw, simultaneously, can avoid operator's sliding hand when tightening the screw.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: screw easily is installed, comprise the first double-screw bolt, be located at spiral shell head on the first double-screw bolt, be located at the tooth that screws of spiral shell crown section, described spiral shell head both sides are provided with screw, and described screw is provided with stubborn head.
As preferably, described stubborn head comprises for coordinate the second double-screw bolt spun, the acting surface that is screwed in the second double-screw bolt other end with screw, after screwing tooth and screwing operation failure, the operator screws in the second double-screw bolt in screw, and hand is acted on two acting surfaces, thereby can easily screw means be arrived to specified position, avoided screw to scrap because screwing the tooth damage simultaneously, saved material, will twist head after screwing screw and unload, thereby keep the space-saving good nature of screw.
As preferably, described acting surface is provided with butterfly shape extended surface, thereby has increased the active area of hand, makes to screw operation more convenient.
As preferably, the center of described acting surface adopts hollow structure, thus sliding hand while having avoided the operator to operate.
Beneficial effect:
The installation that the utility model adopts technique scheme to provide is screw easily, reasonable in design, simple in structure, manufacture easyly, can make screw means by twisting head after the screw means tooth screws operation failure, can avoid screw to cancel, saved material, made screw install more convenient simultaneously, and, twist the dismounting facility of head, the space-saving good nature that can keep screw, simultaneously, can avoid operator's sliding hand when tightening the screw.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is left view of the present utility model.
In figure, the first double-screw bolt 1, spiral shell head 2, screw 21, screw tooth 3, twist 4, second double-screw bolt 41, acting surface 42, center 421, butterfly shape extended surface 5.
Embodiment
As shown in Figure 1-2, screw easily is installed, comprise the first double-screw bolt 1, be located at spiral shell head 2 on the first double-screw bolt 1, be located at spiral shell head 2 tops screw tooth 3, described spiral shell head 2 both sides are provided with screw 21, described screw 21 is provided with stubborn 4, described stubborn 4 comprises that described acting surface 42 is provided with butterfly shape extended surface 5 for coordinate the second double-screw bolt 41 spun, the acting surface 42 that is screwed in the second double-screw bolt 41 other ends with screw 21, and described acting surface 42De center 421 adopts hollow structures.
During real work, after screwing tooth 3 and screwing operation failure, the operator screws in the second double-screw bolt 41 in screw 21, and hand is acted on two acting surfaces 42, thereby can easily screw means be arrived to specified position, avoid screw to scrap because screwing tooth 3 damages simultaneously, save material, to twist 4 after screwing screw and unload, thereby keep the space-saving good nature of screw.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used the first double-screw bolt 1, spiral shell head 2, screw 21, screws tooth 3, twisted the terms such as the 4, second double-screw bolt 41, acting surface 42, center 421, butterfly shape extended surface 5, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
