Abstract
The invention discloses a domestic screw screwing and unscrewing tool which comprises a screwdriver. The screwdriver is in a rod-shaped structure with one end provided with a tool bit, and a through hole with a square section is further formed in the rod-shaped structure. The tool further comprises a U-shaped rod and a rotary handle, the U-shaped rod is used for allowing the screwdriver to pass, and the rotary handle is fixed to the open end of the U-shaped rod. The section of the U-shaped rod is rectangular, the two free ends of the U-shaped rod are fixedly connected with the rotary handle, the screwdriver is arranged on the U-shaped rod in a penetrating mode, and the screwdriver can slide along the U-shaped rod. The U-shaped rod is further sleeved with a rubber ring in a tensioned state. The two ends of the screwdriver are both provided with a rubber ring. By means of the tool, the tool bit on the screwdriver faces different directions by matching different faces of the through hole with different faces of the U-shaped rod. The screwdriver can be conveniently moved to the position where operation is easy. Accordingly, by means of the rotary shaft and/or the U-shaped rod, enough torque can be conveniently applied to a self-tapping screw to screw the self-tapping screw. Meanwhile, the tool is convenient to use.
Description
Technical field
The present invention relates to mechanical fastener Experiment platform technology field, particularly relate to a kind of family expenses mounting/dismounting screw tool utensil.
Background technology
Bolt is a kind of machine components, is generally the cylindrical threaded securing member of adapted nut.Bolt is made up of head and screw rod (with externally threaded cylinder) two parts, and need and nut screw connection during use, for being fastenedly connected two parts with through hole, this type of attachment claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.Divide by the force way connected: point common and have articulation hole.Divide by nose shape: have turret head, round end, square spigot, countersunk head etc.Wherein turret head is the most frequently used.At present, the bolt applying to different field or purposes emerges in an endless stream, and such as requires case hardness high and heart portion has flexible self-tapping screw, for preventing the anticorrosive bolt, high temperature bolt etc. of flow-induced corrosion.But the basic purposes of bolt is the fastening needs being required to meet connector, therefore bolt has, and to meet the tensile strength used be basic demand to bolt.
In prior art, particularly at furniture, in affaires, usually adopt self-tapping screw as connector, in prior art, self-tapping screw cutter is of a great variety, but the general self-tapping screw cutter adopting hand-turning, due to the muscle power of people and tolerance limited, all can easily not apply enough torques to tighten or to relax self-tapping screw to self-tapping screw cutter, like this, just easily cause human muscle and skin to come to harm.
Summary of the invention
For in above-mentioned prior art, particularly at furniture, in affaires, usually adopt self-tapping screw as connector, in prior art, self-tapping screw cutter is of a great variety, but the general self-tapping screw cutter adopting hand-turning, due to the muscle power of people and tolerance limited, all can easily not apply enough torques to tighten or to relax self-tapping screw to self-tapping screw cutter, like this, with regard to the problem easily causing human muscle and skin to come to harm, the invention provides a kind of family expenses mounting/dismounting screw tool utensil.
A kind of family expenses mounting/dismounting screw tool utensil provided by the invention solves problem by following technical essential: a kind of family expenses mounting/dismounting screw tool utensil, comprise screwdriver, described screwdriver is the rod-like structure that one end is provided with cutter head, and in rod-like structure, be also provided with cross section be foursquare through hole;
Also comprise for wearing the U-shaped bar of screwdriver, being fixed on the turning handle of U-shaped bar openend;
The rectangular in cross-section of described U-shaped bar, two free ends of U-shaped bar are all fixedly connected with turning handle;
Described screwdriver is arranged on U-shaped bar, and screwdriver can slide along U-shaped bar; Described U-shaped bar is also arranged with the rubber ring being in tensioning state, and the two ends of screwdriver are provided with rubber ring.
Concrete, adopt cross section to be the form in foursquare through hole and square U-shaped bar cross section, be convenient to realize by through hole not coplanar and U-shaped bar not coplanar coordinate, realize cutter head on screwdriver different towards; Slided along U-shaped bar by screwdriver simultaneously, be convenient to position screwdriver being moved to convenient operation, like this, be convenient to, by turning handle and/or U-shaped bar, apply enough torques to self-tapping screw, take from tapping to fill.Because rubber ring can produce elastic deformation, namely the rubber ring being in tensioning state not only can slide along U-shaped bar, also there is larger frictional force between the two simultaneously, like this, by arranging rubber ring in this instrument, carry out spacing, particularly when this instrument uses to the tighten up a screw two ends of cutter of U-shaped bar, above position-limiting action significantly can improve the stability of driver bit and cap nut relative position relation, is beneficial to the convenience that this instrument uses.
Further technical scheme is:
For the handling making this instrument be suitable for different self-tapping screw, more than one of the quantity of described screwdriver, and different screwdriver has different cutter head forms.
For ease of when this instrument small volume, be convenient on screwdriver, apply torque by turning handle, described turning handle is flat, and two free ends of U-shaped bar are fixedly connected with any side of turning handle.
For ease of changing screwdriver, changing the installment state of screwdriver on this instrument, the type of attachment of turning handle and U-shaped bar is the form of removably connecting.
The present invention has following beneficial effect:
In this structure, adopt cross section to be the form in foursquare through hole and square U-shaped bar cross section, be convenient to realize by through hole not coplanar and U-shaped bar not coplanar coordinate, realize cutter head on screwdriver different towards; Slided along U-shaped bar by screwdriver simultaneously, be convenient to position screwdriver being moved to convenient operation, like this, be convenient to, by turning handle and/or U-shaped bar, apply enough torques to self-tapping screw, take from tapping to fill.
Because rubber ring can produce elastic deformation, namely the rubber ring being in tensioning state not only can slide along U-shaped bar, also there is larger frictional force between the two simultaneously, like this, by arranging rubber ring in this instrument, carry out spacing, particularly when this instrument uses to the tighten up a screw two ends of cutter of U-shaped bar, above position-limiting action significantly can improve the stability of driver bit and cap nut relative position relation, is beneficial to the convenience that this instrument uses.
