Abstract
The utility model relates to a screw with no need for a screwdriver during screwing. The screw comprises a screwing knob and a screw body. When the screw is used, the screw body is aligned to a threaded hole and inserted into the threaded hole, and a butterfly handle of the screwing knob is turned to enable a screw rod of the screw body to be meshed with and screwed into the threaded hole. When the screw is screwed, the screwing knob is continuously turned, deformation and breakage under stress occur at the connecting position of the end portion of a hollow cylindrical body and the edge of a screw cap, so that the hollow cylindrical body on the screwing knob is separated from the screw cap, and threaded meshing is finished. The problem that screwdriver cannot be always found at any place and is not matched with the screw in size is solved, and the screw can be used at any time anywhere.
Description
Technical field
The utility model belongs to the screw means technical field, particularly a kind of screw that does not need screw-driver to twist.
Background technique
Screw on current market mostly needs screw-driver to screw, but screw-driver not necessarily can both find anywhere, and exists the unmatched inferior position of model.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of screw that does not need screw-driver to twist, not necessarily can both find anywhere to solve screw-driver, and exist the unmatched problem of model, screw can not spinned by screw-driver and not tighten with taking with usefulness.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of screw that does not need screw-driver to twist is provided, comprise and screw button and screw, one end of described screw is threaded stem, the other end is nut, described button one end that screws is rotatable handle, the end of the other end is hollow cylinder, the end of described hollow cylinder is connected with the edge of nut, the top of described nut is positioned at hollow cylinder, the diameter of described nut is identical with the diameter of hollow cylinder, the described button that screws, the medial axis counterpoise of nut and screw is combined on the same straight line.
The described rotatable handle that screws button one end is buttferfly-type, and the end of the other end is hollow cylinder, connects by the solid conical transition between the described rotatable handle that screws button and the hollow cylinder.
The end of described hollow cylinder and the edge of nut are by being welded to connect.
The sidewall wall thickness of described hollow cylinder is the 0.5-3 millimeter.
Beneficial effect
The utlity model has following advantage:
1, not needing specially to seek the screw-driver that mates with the screw model is tightened.
2, the edge of the end of hollow cylinder and nut uses repeatedly by being welded to connect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: screw button 1, hollow cylinder 2, nut 3, screw 4, threaded stem 5.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of screw that does not need screw-driver to twist, comprise and screw button 1 and screw 4, one end of described screw 4 is that threaded stem 5, the other end are nut 3, described button 1 one ends that screw are that the end of rotatable handle, the other end is hollow cylinder 2, the end of described hollow cylinder 2 is connected with the edge of nut 3, the top of described nut 3 is positioned at hollow cylinder 2, the diameter of described nut 3 is identical with the diameter of hollow cylinder 2, and the described medial axis counterpoise that screws button 1, nut 3 and screw 4 is combined on the same straight line.
The described rotatable handle that screws button 1 one ends is buttferfly-type, and the end of the other end is hollow cylinder, connects by the solid conical transition between the described rotatable handle that screws button 1 and the hollow cylinder.
The edge of the end of described hollow cylinder 2 and nut 3 is by being welded to connect.
The sidewall wall thickness of described hollow cylinder 2 is the 0.5-3 millimeter.
Be not difficult to find out, when the utility model uses screw, screw 4 is aimed at tapped hole to be inserted, screw the buttferfly-type handle of button 1, the threaded stem 5 that screw 4 is had screws in the tapped hole engagement, when screw 4 screws, continue to screw button 1, the joint at hollow cylinder 2 ends and nut 3 edges produces the stress deformation fracture, and the hollow cylinder 2 that screws on the button 1 is separated with nut 3, finishes the screw engagement.
