Abstract

The invention discloses a novel fastener and relates to a fastener. The novel fastener comprises a handle part (1), a screw head (2), a bolt (3), a thread (4) and a nut, one end of the screw head (2) is connected with the handle part (1), the other end of the screw head (2) is connected with the bolt (3) provided with the thread (4), and the bolt (3) is connected with the nut (5) through the thread (4). The novel fastener is simple in structure, novel and unique in design, convenient to mount and use and free of slipping during use. The novel fastener which can be not only connected in a manual screwing way but screwed by a screw driver is good in fastening effect, and cost is saved.

Description

A kind of novel fastener

Technical field:

The present invention relates to a kind of fastening piece, be specifically related to a kind of novel fastener.

Background technique:

The general name of the class mechanical parts that fastening piece adopts when as a whole for two or more parts are fastenedly connected into, on various machinery, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous.Existing fastening piece description is various, need in use special tightening tool, for example bottle opener or spanner are tightened fastening piece or unscrew, it on the screw head of general screw fastener, is all the groove that is provided with cross or yi word pattern, when using bottle opener to tighten, easily crosshead or flat head are polished, and easily occur the situation of stripped thread, cause cost waste.

Summary of the invention:

The object of this invention is to provide a kind of novel fastener, it is simple in structure, novel in design unique, easy to install, the phenomenon that in use there will not be stripped thread, not only can adopt manual tightening way that fastening piece is connected, and can also tighten with bottle opener, fastening effective, saved cost.

In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it comprises handle member 1, screw terminal 2, double-screw bolt 3, screw thread 4 and nut 5, one end of screw terminal 2 is connected with handle member 1, the other end of screw terminal 2 is connected with double-screw bolt 3, on double-screw bolt 3, be provided with screw thread 4, double-screw bolt 3 is connected with nut 5 by screw thread 4.

On described screw terminal 2, be provided with cruciform groove 2-1.

When the present invention uses, operator can pass through handle with sleeve part 1, and double-screw bolt 3 is screwed into or is screwed out in nut 5, also can be by using bottle opener that double-screw bolt 3 is screwed into or is screwed out in nut 5.

The present invention has following beneficial effect: it is simple in structure, novel in design unique, easy to install, the phenomenon that in use there will not be stripped thread, not only can adopt manual tightening way that fastening piece is connected, and can also tighten with bottle opener, fastening effective, saved cost.

Accompanying drawing explanation:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of screw terminal in the present invention;

Fig. 3 is the structural representation of screw terminal in embodiment two in the present invention.

Embodiment one:

With reference to Fig. 1-2, this embodiment is taked following technological scheme: it comprises handle member 1, screw terminal 2, double-screw bolt 3, screw thread 4 and nut 5, one end of screw terminal 2 is connected with handle member 1, the other end of screw terminal 2 is connected with double-screw bolt 3, on double-screw bolt 3, be provided with screw thread 4, double-screw bolt 3 is connected with nut 5 by screw thread 4.

On described screw terminal 2, be provided with cruciform groove 2-1.

When this embodiment is used, operator can pass through handle with sleeve part 1, and double-screw bolt 3 is screwed into or is screwed out in nut 5, also can be by using bottle opener that double-screw bolt 3 is screwed into or is screwed out in nut 5.

This embodiment has following beneficial effect: it is simple in structure, novel in design unique, easy to install, the phenomenon that in use there will not be stripped thread, not only can adopt manual tightening way that fastening piece is connected, can also tighten with bottle opener, fastening effective, saved cost.

Embodiment two: with reference to Fig. 3, this embodiment is to be provided with yi word pattern groove 2-2 on described screw terminal 2 with the difference of embodiment one, and other composition and annexation are identical with embodiment one.
