Abstract

The utility model discloses a novel file, which mainly comprises a handle and a file body. The utility model has the constructional characteristic that the handle is fixedly connected with one end of a connecting rod, and the other end of the connecting rod is connected with the file body. Thus the file body of the utility model can extend into a concave table board of a workpiece for file finishing. The utility model has the advantage of simple structure.

Description

A kind of novel file

The utility model belongs to a kind of novel file, is particularly useful for processing the concave station face file finishing of the workpiece with concave station face.

Existing file generally connects body by handle to be formed, and is generally straight type, can not the wide-angle bending, thereby when the concave station face of filers' part, be difficult for making it file finishing, and body fixedlys connected with handle, can not change.

The purpose of this utility model provides the novel file that a kind of concave station face of changing body and making body stretch into workpiece carries out file finishing work.

The purpose of this utility model is achieved in that the novel file that comprises handle and body, and its design feature is that an end of handle and connecting rod 3 is fixedly linked, and the other end of connecting rod links to each other with body.

In addition, connecting rod of the present utility model adopts fold-type or curved, and the file face of body is arc, ball-cut shape or platybasic type.

The utility model since in adjunction between handle and the body long enough connecting rod, and body has difformity and replaceable, thereby the easy concave station face of file finishing workpiece.

Below in conjunction with accompanying drawing and example the utility model is described in detail:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the user mode figure of Fig. 1.

Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are body master among Fig. 1 left three-view diagram of bowing.

Fig. 7 is the body master vertical view among Fig. 1.

As depicted in figs. 1 and 2, connecting rod 3 inserts in the handle 1 fixing, connecting rod adopts " " type, its other end has screw thread tightly to be connected with screw thread with body, general connecting rod screws on nut 4 earlier and screws on body 2 again, then nut is made it to press body to backspin, make it tightly fixing with connecting rod, during use, curved profiled bar easily stretches into workpiece concave station face, then the body file finishing it, body can adopt Fig. 3, Fig. 4 or Fig. 5 or Fig. 6 or Fig. 7 or the like different shape such as camber, the body of ball crown type or platybasic type file face, as long as body is drilled with internal thread hole and is connected with the connecting rod external screw thread, reinforce the work that gets final product with nut 4 then.

Claims

1, a kind of novel file comprises handle (1) and body (2), it is characterized in that an end of handle and connecting rod (3) is fixedly linked, and the other end of connecting rod (3) links to each other with body.

2, novel file according to claim 1 is characterized in that the other end of connecting rod is provided with screw thread, and this end is rotary with the nut (4) that is used to tighten body and screws on body.

3, novel file according to claim 1 is characterized in that connecting rod (3) adopts fold-type or curved connecting rod.

4,, it is characterized in that the body body that to adopt its file face be camber or ball crown type or platybasic type according to claim 1 or 2 or 3 described novel files.
