Abstract

The utility model relates to a triangular scraper which belongs to the field of industrial cutters and comprises a scraper body and a handle. The handle is in a cylinder shape, the port of one end of the handle is provided with an internal thread, the other end of the handle is close, and crossknurl is manufactured on the outer surface of the handle; the tail part of the scraper body is provided with a connecting piece which is a cylinder with the outer surface provided with an external thread, and one end of the cylinder is provided with a bulge. The scraper body and the handle of the triangular scraper adopt a movable assembly structure; when the scraper is used, the scraper body is screwed down to be reversely inserted into the handle, the bulge is rotated to fix the scraper body in the handle through the connection of the internal thread of the handle and the external thread on the connecting piece of the scraper body, so that a knifepoint and an edge can not expose outside, and the problem that the knifepoint and the edge scuffs a user in the storing process is solved; and in addition, the connection is convenient, save and reliable. The crossknurl is manufactured at the outer surface of the handle of the triangular scraper so as to enhance the hold of the user and prevent skid during the work.

Description

A kind of triangular scraper

Technical field:

The utility model relates to a kind of triangular scraper, belongs to the industrial knife field.

Background technology:

Triangular scraper is the instrument that the round piece inner surface is carried out manual scraping processing, all the time, the triangular scraper handle all is to adopt wooden handle, with cutter hub be overall structure, point of a knife, blade are exposed for a long time outside, deposit the thing that the scuffing personnel are often arranged in the process after the use and take place, bring inconvenience to work.

Summary of the invention:

The purpose of this utility model is: cutter hub is collected in the handle when providing a kind of scraper not use, handle double as protective sleeve; The point of a knife, the blade that solve existing triangular scraper are exposed for a long time outside, deposit the triangular scraper that scuffing personnel problem is often arranged in the process after the use.

The utility model is to realize above-mentioned purpose by following technical solution:

A kind of triangular scraper, it is made up of cutter hub and handle, it is characterized in that: handle is one cylindric, is shaped on internal thread in the port of an end, and the other end is an enclosed construction, and the cutter hub afterbody is shaped on connector.

Described connector is that outer surface is shaped on externally threaded cylinder, and an end of connector is shaped on a projection.

Described handle outer surface is shaped on cross knurled.

The utility model beneficial effect compared with prior art is: the structure of cutter hub and handle employing activity assembling, and make scraper can be collected in the handle in off working state, effectively prevented from after use, to deposit the personnel's that scratch in the process problem.The handle outer surface is shaped on cross knurled, has increased user's the dynamics of controlling, and prevents to occur skidding when work.

Description of drawings:

Fig. 1 is the structural representation of triangular scraper deployed condition;

Fig. 2 is the structural representation of triangular scraper collecting state;

Fig. 3 is the structural representation of handle;

Fig. 4 is the structural representation of cutter hub.

Among the figure: 1, handle, 2, cutter hub, 3, connector, 4, external screw thread, 5, projection, 6, internal thread, 7, cross knurled.

The specific embodiment:

This triangular scraper is made up of cutter hub 2 and handle 1, and handle 1 is one cylindric, is shaped on internal thread 6 in the port of an end of handle 1, and the other end is an enclosed construction.The afterbody of cutter hub 2 is shaped on connector 3, and connector 3 is a cylinder, and the outer surface of connector 3 is shaped on external screw thread 4, and is connected with the internal thread 6 of handle 1 by external screw thread 4.One end of connector 3 is shaped on a projection 5.The outer surface of handle 1 is shaped on cross knurled 7, its objective is the dynamics of controlling that increases the user, prevents to skid when work.

The utility model screws out cutter hub 2 by projection 5 when work in handle 1, oppositely the back is connected with the internal thread 6 of handle 1 port by the external screw thread 4 on the connector 3 of cutter hub 2, promptly becomes the triangular scraper of band handle.After using, cutter hub 2 is screwed off, oppositely insert in the handle 1 again, rotation projection 5, the external screw thread 4 on the internal thread 6 by handle 1 and the connector 3 of cutter hub 2 is connected, and cutter hub 2 can be fixed in the handle 1, make point of a knife, blade not exposed outside, solved the problem of depositing the personnel that scratch in the process, and easy to connect, safe and reliable.
