Description

A knife handle connecting device

technical field

The utility model relates to a knife handle connecting device.

Background technique

The connection between the tool and the tool handle is generally fixed, that is, one tool handle is equipped with one tool. The fixed structure has great limitations and is not flexible enough to use;

However, the handles of some existing replaceable knives are usually threaded. The disadvantage of this installation method is that the diameter and length of various types of knives must be the same, and it cannot be used universally for knives with different diameters and different lengths. Moreover, the fixing method adopts screw thread installation and has a short service life.

Contents of the invention

The technical problem to be solved by the utility model is to provide a simpler installation method, the diameter and length of the tool can be changed at will, and the specified tool can be clamped as long as the appropriate collet is selected, and the clamping method is fixed and easy to use. More flexible handle connection device.

The utility model is realized through the following technical solutions: it includes a handle body, one end of the handle body is provided with a collet installation cavity, the other end of the body is provided with a fixed cavity, the fixed cavity communicates with the collet installation cavity, and the handle body Both ends of the collet are tapered, the cavity surface of the collet installation cavity is conical, the inner diameter of the opening end of the collet installation cavity is larger than the inner diameter of any part inside the collet installation cavity; a collet screw is installed in the fixed cavity for fixing The collet part, the collet is connected with the collet installation cavity through the Morse taper, the collet is facing the collet screw fixing part, the body fixing cavity is provided with a screw fixing end, the collet is connected with the collet screw at the fixing part of the handle body The tapered surface of the collet installation cavity fits to fix, and the tool is installed in the collet and fixed by the collet.

As a preferred technical solution, a tool mounting cavity is provided at the outer end of the collet, the tool is installed in the tool mounting cavity, one end of the tool is exposed outside the collet, and the inner end of the tool is clamped by the collet.

As a preferred technical solution, the tool and the collet are fixed and clamped by thermal expansion and contraction.

The beneficial effects of the utility model are: the utility model has a simple structure, and the collet can be quickly replaced to replace different tools, and the collet is connected with the body through the Morse taper, the positioning is fast, and the screw fixing part is fixed twice, It is more stable, the collet can be freely replaced according to different tool lengths and diameters, and the tool loading is faster.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings based on these drawings without creative work.

Fig. 1 is the structural representation of the body of the present utility model;

Fig. 2 is the structural representation of collet of the present utility model;

detailed description

All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and/or steps.

Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

As shown in Figure 1, it includes a body 1, one end of the body 1 is provided with a collet installation cavity 2, the other end of the body 1 is provided with a fixed cavity 3, the fixed cavity 3 communicates with the collet installation cavity 2, and the two ends of the body 1 They are all in the shape of a cone, the cavity surface of the collet installation chamber 2 is in the shape of a cone, and the inner diameter of the open end of the collet installation chamber 2 is larger than the inner diameter of any part inside the collet installation chamber;

As shown in Figure 2 and Figure 3, a collet screw fixing part 4 is installed in the fixing cavity 3, the collet 5 is connected with the collet installation cavity 2 through Morse taper, and the collet 5 is set facing the collet screw fixing part 4 A screw fixing end 6, the inside of the collet is fixed by the collet screw fixing part 4 and the screw fixing end 6, and the tool is installed in the collet and fixed by the collet.

The outer end of the collet is provided with a cutter mounting cavity 7, the cutter is installed in the cutter mounting cavity, one end of the cutter is exposed outside the collet 5, and the inner end of the cutter is clamped by the collet.

The tool and the collet 5 are fixed and clamped by means of thermal expansion and contraction, that is, when the tool needs to be replaced, just replace the corresponding different collets, put the corresponding tool into the corresponding collet, and then insert the collet The collet is then loaded into the body. Since the collet and the collet installation cavity are installed with Morse taper, different types of collets can be assembled with the body.

When the tool is loaded into the collet, the tool is fixed by the principle of thermal expansion and contraction, and the collet pre-cools and shrinks to clamp the tool, and the clamping is fast.

The beneficial effects of the utility model are: the utility model has a simple structure, and the collet can be quickly replaced to replace different tools, and the collet is connected to the body through the Morse taper, the positioning is fast, and the screw fixing part is fixed twice, It is more stable, the collet can be freely replaced according to different tool lengths and diameters, and the tool loading is faster.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
