Described extension spring is provided with two, and two extension spring one ends connect the broach shell body by securing member respectively, and the other end connects respectively backstay, and described backstay is installed on drag hook.
Described backstay is designed to screw-rod structure, and is fitted with nut on it.
Described backstay end is provided with pulling eye.
The end bevel shape of described drag hook or circular-arc.
Described being equipped with on handle of a knife retaining mechanism end broach shell body has positioning spline.
Described being equipped with on handle of a knife retaining mechanism end broach shell body has positioning spline.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, have the following advantages:
1, this knife sleeve structure practicality scope is wider, is applicable to HSK and Capto all size handle of a knife, and handle of a knife is fixed in handle of a knife in broach shell by drag hook and spring assembly, and mechanism is succinct, and is attractive in appearance.
2, this knife sleeve structure is simple, utilizes dexterously the combination of drag hook and spring, makes drag hook compress handle of a knife, overcomes the drawback of using the complex combination such as steel ball, pushing block, spring, support, push rod in prior art.
3, in this broach shell, all part production technologies are simple, and required precision is low.And in prior art, material, fineness, hardness, precision and the production technology of the parts such as support, pushing block, steel ball all have higher requirements.
4, this broach shell assembly technology work is simple.In prior art, for sliding friction, and the amount of ejecting of push rod needs accurate adjustment to push rod in support, otherwise can affect the reliability of broach shell function.
