Abstract
The utility model relates to a screw clamping mounting structure which comprises a tool shank and a blade, wherein the blade is fixed at one end of the took shank through a screw. The screw clamping mounting structure is characterized in that a stepped threaded hole with a smaller upper part and a larger lower part is arranged at the end part of the tool shank; a threaded sleeve is arranged in the stepped threaded hole; a screw is screwed into the threaded sleeve after passing through the blade; the wider end of the threaded sleeve is arranged under the threaded hole; and the narrower end of the threaded sleeve is arranged above the stepped threaded hole. The screw clamping mounting structure has the technical effects that as the threaded sleeve is mounted reversedly, the acting force which is eventually applied on the blade acts on the step of the threaded hole of the tool shank instead of the thread of the threaded hole of the tool shank; and the threaded hole of the tool shank exists only for fixing the threaded sleeve. Therefore, the service life of the tool shank is prolonged.
Description
Technical field
The utility model relates to a kind of screw clamp compact form mounting structure, especially a kind of structure for installation car cutting knife tool and handle of a knife.
Background technology
In metal machinery turning processing, generally on the handle of a knife adopt that screw clamp compact form structure (as shown in Figure 1) is installed, fixed blade, the active force of this kind structure when replacing, compression blade directly acts on the screwed hole of handle of a knife 6 by screw 5, to fix blade 7.Owing to need often to change, to compress blade, cause the screwed hole of handle of a knife to damage easily, and then cause and whole handle of a knife is scrapped.The clamping structure of another kind of turning cutting tool and handle of a knife as shown in Figure 2, increased a swivel nut 8, offer a up big and down small stepped hole at handle of a knife 6, swivel nut 8 is placed in the stepped hole, make like this replacing, the active force when compressing blade, indirectly act on the screwed hole of handle of a knife by swivel nut, the screw thread of swivel nut damages easily, the screwed hole of handle of a knife then is not easy to damage, and has just prolonged the service life of handle of a knife by this structure.But above two kinds of structures have a common ground, be exactly the active force that finally compresses blade be to act on the screw thread of handle of a knife screwed hole, screw thread always can damage through screwing repeatedly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of screw clamp compact form mounting structure is provided, and the active force of blade is acted on the step of handle of a knife screwed hole, to prolong the service life of handle of a knife.
According to the technical scheme that the utility model provides, described screw clamp compact form mounting structure comprises handle of a knife and blade, and blade is fixed by screws in an end of handle of a knife; Feature is: be provided with up-small and down-big step screwed hole in the end of described handle of a knife, in this step screwed hole swivel nut be set, screw passes blade and is screwed in the swivel nut.
A wider end is positioned at the below of step screwed hole on the described swivel nut, and a narrower end is positioned at the top of step screwed hole on the swivel nut.
Technique effect of the present utility model is: the utility model is not to act on the screw thread of handle of a knife screwed hole so that finally compress the active force of blade, but acts on the step of handle of a knife screwed hole by the anti-dress of swivel nut; Although the handle of a knife screwed hole exists, only be to play fixedly swivel nut usefulness.So just prolonged the service life of handle of a knife.
Description of drawings
Fig. 1 is the structural representation of available technology adopting screw fixed cutting tool and handle of a knife.
Fig. 2 is the structural representation of available technology adopting screw and swivel nut fixed cutting tool and handle of a knife.
Fig. 3 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 3: screw clamp compact form mounting structure comprises handle of a knife 1, swivel nut 2, blade 3, screw 4 etc.
The utility model comprises handle of a knife 1 and blade 3, and blade 3 is fixed on an end of handle of a knife 1 by screw 4; Be provided with up-small and down-big step screwed hole in the end of described handle of a knife 1, in this step screwed hole swivel nut 2 be set, screw 4 passes blade 3 and is screwed in the swivel nut 2; A wider end is positioned at the below of step screwed hole on the described swivel nut 2, and a narrower end is positioned at the top of step screwed hole on the swivel nut 2.
The utility model adopts the structures of swivel nut 2 anti-dresses, is about to the wider end of swivel nut 2 towards the below of step screwed hole, and the narrower end of swivel nut 2 is towards the top of step screwed hole; The screw thread in handle of a knife 1 end thread hole only is to play fixedly swivel nut 2 usefulness like this, and stressed is step surface.
Screw clamp compact form structure described in the utility model than prior art more can prolong handle of a knife service life the utility model when blade 3 clamps, the active force of blade 3 is delivered to swivel nut 2 by screw 4, is delivered on the step of the step screwed hole on the handle of a knife 1 by swivel nut 2 again.
Claims (2)
