Description

Small file handle and small file

Technical Field

The utility model relates to a handle of a small file and the small file, and belongs to the technical field of manual filing tools.

Background

The file is a hand tool for filing work piece, and can be used for micro-machining the surface layers of metal, timber, leather and the like. Because the shapes of the tips of the files are different when the files process different processed workpieces, the files are of various types, such as common flat files, round files, half round files, triangular files and the like, and a plurality of files are required to be stock.

In the prior art, each file is provided with a file handle independently to become an independent file, so that the cost is high; in addition, in order to facilitate holding and applying force, the file handles are often made larger, so that when each file is provided with one file handle, the occupied space is larger, and the file is inconvenient to store and transport. Especially for small files with the length of 100-150 mm and the outline diameter of usually less than 6mm, the small files are usually sold in sets, and when each file is provided with one file handle, the contradiction of space occupation of the handle is more prominent.

The chinese patent with publication number CN218799576U discloses a combined file, which can be used after the file tongue is inserted into the file handle and fixed by the cooperation of the bump and the notch, and when another file body needs to be replaced, the file tongue is driven to move by pressing the button to separate the bump from the notch, and then the file body can be pulled out. However, since the rasp does not require much force, the structure of the combined rasp is complicated, and the structure is not suitable for the rasp having a small size, but is simple in structure and convenient to install and use, which is more important for the rasp.

Detailed Description

The present embodiment, shown in fig. 1-4, relates to a rasp handle and rasp using the same, the rasp including a rasp handle and a rasp body 3.

The rasper handle is shown in fig. 2 and 3, and comprises a handle body 1, one end of the handle body 1 is provided with a connecting portion, the connecting portion is provided with a cavity extending along the length direction, one end of the cavity, which is far away from the handle body 1, is provided with an opening, the periphery of the connecting portion is provided with an external thread 8 and a screw cap 2 matched with the external thread 8, the handle body 1 is provided with a blind hole 9 extending along the length direction of the blind hole 9, and an orifice of the blind hole 9 is positioned at the bottom of the cavity. As shown in fig. 2-4, a plurality of elastic sheets 5 are arranged in the cavity of the connecting part along the circumferential direction of the orifice, the elastic sheets 5 extend from the orifice to the opening direction, and the elastic sheets 5 are enclosed together to form a hollow clamping structure; the top cover plate of the spiral cover 2 is provided with a through hole coaxial with the blind hole 9, a cone barrel 6 is arranged in the spiral cover 2 along the circumferential direction of the through hole, one end of the cone barrel 6 is fixedly connected with the top cover plate of the spiral cover 2, and the elastic piece 5 is inserted into the cone barrel 6. As shown in fig. 2 and 3, the closer to the top cover plate, the smaller the inner diameter of the cone 6 is, so that a splayed inclined surface is formed in the cone 6, and the elastic piece 5 is convenient to clamp.

As shown in fig. 1-3, one end of the file body 3 is provided with a file handle 4, and the file handle 4 is inserted into a blind hole 9 along a clamping structure from a through hole of the screw cap 2 and is fixed on a small file handle through the cooperation of the cone 6 of the screw cap 2 and the clamping structure. The cross section of the file handle 4 is preferably polygonal or circular, so that the file handle is convenient to process, install and use.

When the small file of the embodiment is used, the screw cap 2 is screwed out firstly, then the file handle 4 of the small file is inserted, the screw cap 2 is screwed, the elastic piece 5 is clamped by the cone 6 in the screw cap 2 in the screwing process of the screw cap 2, and the file handle 4 is clamped by the elastic piece 5 at the same time, so that the small file can be used. Preferably, the elastic pieces 5 are three pieces in total, are arranged in a three-jaw shape, and are more suitable for clamping the file handle 4.

The embodiment can be further improved as follows: the inner side of the elastic piece 5 is provided with first anti-skidding lines, and the periphery of the file handle 4 is provided with second anti-skidding lines. The shapes of the first anti-skid pattern and the second anti-skid pattern are not limited, and the following two embodiments are preferred: 1) The first anti-skid patterns and the second anti-skid patterns are all twill lines, and the first anti-skid patterns and the second anti-skid patterns are vertical; 2) The first anti-skid stripes and the second anti-skid stripes are both wavy point-shaped anti-skid stripes. Thus, the file body 3 can be prevented from rotating along with the handle as much as possible when in use, and the using effect is influenced.
