Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a conversion handle of a knife, including handle of a knife 1 and machine tool interface handle of a knife 2, the die cavity has been seted up on the inner chamber right side of machine tool interface handle of a knife 2, the top intercommunication of die cavity has the post type passageway, the bottom intercommunication of die cavity has oblique passageway, the right side of handle of a knife 1 is provided with handle blind rivet 7, and handle of a knife blind rivet 7 presss from both sides 5 to matching with elasticity, handle of a knife 1 pegs graft mutually with the die cavity, the inner chamber right side of die cavity is pegged graft and is had spring 4, spring 4's left side is provided with elasticity and presss from both sides cover 5, and elasticity presss from both sides cover 5 pegs graft in the inner chamber of die cavity, the inner wall threaded connection of post type passageway has screw pin 3, the inner wall threaded connection of oblique passageway has housing screw 6.

As preferred scheme, still further, elastic jacket 5 divide into connecting portion and jump ring portion two parts, and connecting portion and spring 4 are connected, and jump ring portion compresses tightly with handle blind rivet 7 and is connected, fixes to handle blind rivet 7.

Preferably, the center of the outer wall of the elastic jacket 5 is concave.

Preferably, the tool shank 1, the tool shank rivet 7, the elastic jacket 5 and the spring 4 are arranged in sequence from left to right.

The detailed connection means is a technique known in the art, and the following mainly describes the working principle and process, and the specific operation is as follows.
