Specific implementation mode

The embodiment of the utility model is described in further detail with reference to the accompanying drawings and examples.Following embodiment For illustrating the utility model, but cannot be used for limiting the scope of the utility model.

In the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more；Term The orientation of the instructions such as "upper", "lower", "left", "right", "inner", "outside", " front end ", " rear end ", " head ", " tail portion " or position are closed System is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, rather than Indicate or imply that signified device or element must have a particular orientation, with specific azimuth configuration and operation, therefore cannot It is construed as a limitation of the present invention.In the description of the present invention, it should be noted that unless otherwise specific regulation And restriction, term " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, Or it is integrally connected；It can be mechanical connection, can also be electrical connection；It can be directly connected, intermediary can also be passed through It is indirectly connected.For the ordinary skill in the art, it can understand above-mentioned term in the present invention with concrete condition Concrete meaning.

As shown in Figs 1-4, the mobile shaft type utility knife described in the present embodiment, including handle of a knife 1, blade 2 with run through handle of a knife 1 With the reducing shaft 3 of blade 2, placed cavity 11 is provided in handle of a knife 1, blade 2 is slidably disposed in placed cavity 11, blade 2 Lower end, which is provided with, facilitates reducing shaft 3 to pass through the first jack 21, being provided at both ends with of handle of a knife 1 facilitate reducing shaft 3 to pass through the Two jacks 12.

Reducing shaft 3 includes sliding part 31, first connecting portion 32 and the second connecting portion that bar diameter is sequentially increased from top to bottom 33。

The aperture of first jack 21 is adapted with the bar diameter of first connecting portion 32, and the aperture of the second jack 12 is connect with second The bar diameter in portion 33 is adapted.

First jack 21 can in axial direction be arranged multiple, it can be achieved that adjusting the length that blade 2 stretches out, the first jack 21 with Second jack 12 forms the maintenance through-hole for facilitating reducing shaft 3 to be inserted into, the first connecting portion 32 and second of reducing shaft 3 when overlapping Interconnecting piece 33 fastens grafting with the first jack 21 and the second jack 12 respectively, plays the role of fixed limit to blade 2, prevents knife Body 2 is fallen in handle of a knife 1, and since reducing shaft 3 is the structure that bar diameter is sequentially increased from top to bottom, so working as reducing shaft 3 when being inserted into maintenance through-hole, and blade 2 can play position-limiting action to its second connecting portion 33, and reducing shaft 3 is made not wear completely Handle of a knife 1 and blade 2 are crossed, to realize fixed effect.

The sliding slot 13 for facilitating reducing shaft 3 to slide, the size and sliding part of sliding slot 13 are provided between second connecting hole 12 31 bar diameter is adapted, and sliding slot 13 is the long strip type opening for being connected to the second connecting hole 12, and sliding part 31 can be in sliding slot 13 back and forth Sliding, to drive contraction of the blade 2 in the cavity 11 of handle of a knife 1.

It is provided with the scale 14 for measuring size on handle of a knife 1,2 upper end of blade is provided with for grip bolt or nut Sets of holes 22, sets of holes 22 can be arranged as required to the different hole of multiple pore sizes, to cope with the bolt or spiral shell of different model Mother, scale 14 can measure object instead of ruler, and sets of holes 22 can replace spanner to complete the elastic work of bolt or nut, and two The setting of person improves the functionality of cutter, facilitates in daily life or is used when outgoing.

31 upper end of sliding part of reducing shaft 3 is provided with key ring 4, and the setting of key ring 4 plays limit to reducing shaft 3 Effect, prevents it from falling off on handle of a knife 1, and the setting of key ring can hang over cutter in key chain, and people is facilitated to take with oneself Band provides easy-to-use.

The operation principle of the utility model is：When cutter needs in use, by the first connecting portion 32 of reducing shaft 3 and the Two interconnecting pieces 33 are detached from the first jack 21 and the second jack 12 respectively, at this point, reducing shaft 3 is in sliding slot 13, pull reducing Shaft 3 makes the sliding in sliding slot 13 of sliding part 31, and then blade 2 is released out of handle of a knife 1 cavity 11, waits for that sliding part 31 moves When moving in the maintenance through-hole of 11 outlet port of cavity formed by the first jack 21 and the second jack 12, multidiameter shaft is pressed Second plug division 33 of bar 3 makes first connecting portion 32 and second connecting portion 33 enter in maintenance through-hole, and respectively with the first jack 21 and second jack 12 fasten grafting, to complete the fixation of handle of a knife 1 and blade 2, it is to be used it is complete after, the top of pressing sliding part 21 End makes first connecting portion 32 be detached from maintenance through-hole with second connecting portion 33 and repeatedly blade 2 is contracted to sky by aforesaid operations In chamber 11 and it is fixed.

The embodiments of the present invention provide for the sake of example and description, and are not exhaustively or to incite somebody to action The utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art See.Selection and description embodiment are and to make this field to more preferably illustrate the principles of the present invention and practical application Those of ordinary skill is it will be appreciated that various embodiments with various modifications of the utility model to design suitable for special-purpose.
