When pressing described pressure handle, described knife rest can move to and make described blade stretch out described housing.

Optionally, described elastic component is positioned at the side of described knife rest towards described blade.

Optionally, described elastic component is helical spring.

Optionally, be installed with guide pillar in described housing, axially extending along the moving direction of described knife rest of described guide pillar, described helical spring is sheathed on outside described guide pillar.

Optionally, be provided with cavity in described housing, described guide pillar is positioned at described cavity

Optionally, described pressure handle stretches out described housing away from one end of described knife rest.

Optionally, also comprise clamping part, described blade is fixedly arranged on described clamping part, and described clamping part is connected with described knife rest.

Optionally, described clamping part has slot away from the side of described knife rest, and described blade is inserted in described slot; Or described clamping part is two clamping plates, and described cutting blade clip is located between two clamping plates.

Compared with prior art, the technical solution of the utility model has the following advantages:

Blade is arranged in housing by knife rest, and knife rest can move relative to housing, moves in use and makes blade stretch out housing, and make blade be retracted in housing when not using, be not easy scratching fingers, safety coefficient is high.

Detailed description of the invention

For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail specific embodiment of the utility model below in conjunction with accompanying drawing.

The utility model embodiment provides a kind of hand-held carving knife, and with reference to Fig. 2-4, comprise housing 10, the knife rest 20 be connected with housing 10, knife rest 20 is provided with blade 30; Knife rest 20 can move to relative to housing 10 and make blade 30 stretch out housing 10 or retreat in housing 10.

Also comprise elastic component 40, one end of elastic component is to being located at housing 10, and the other end is to being located at knife rest 30.Elastic component 40 provides restoring force for cutter setting frame 20, and it when being subject to external force, elastic deformation occurs, and when external force disappears, then knife rest 20 counter motion can be driven to original state.Elastic component 40 in the present embodiment is helical spring.Helical spring quantity can be arranged as required, and in the present embodiment, helical spring has two, is all positioned at the side of knife rest 20 towards blade, and is positioned at the two ends of knife rest 20.

Continue with reference to Fig. 2-4 and composition graphs 5-6, the hand-held carving knife of the present embodiment also comprises pressure handle 50, and be positioned at the side of knife rest 20 away from blade 30, pressure handle 50 is connected with knife rest 20, and stretches out housing 10 in the one end away from knife rest 30.In use, press pressure handle 50, pressure handle 50 moves towards the direction of stretching out housing 10 with movable knife rack 20 and blade 30 user, and the active force that helical spring is subject to knife rest 20 is extruded compression, savings restoring force; When not in use, unclamp pressure handle 50, external force disappears, and helical spring orders about knife rest 20 oppositely movement under the effect of restoring force, and band cutting blade 30 and pressure handle 50 oppositely move to gets back to original state.

In other embodiments, elastic component can also select torsion spring, sheet spring etc., is not limited only to the helical spring in the present embodiment.

As can be seen here, in the hand-held carving knife of the present embodiment, blade 30 is arranged in housing 10 by knife rest 20, only has and just stretches out housing 10 in use, and being then retracted in housing 10 when not using, being not easy scratching fingers, safety coefficient is high.

Guide pillar 11 is installed with, axially extending along the moving direction of knife rest 20 of guide pillar 11 in housing 10; The corresponding helical spring of each guide pillar 11, helical spring is sheathed on outside corresponding guide pillar 11.The two ends of knife rest 20 are also sheathed on outside guide pillar 11, can move back and forth along the length direction of guide pillar 11.

In order to fixing guide pillar, the present embodiment arranges cavity 10a in housing 10, and each guide pillar 11 lays respectively in a cavity 10a, and the two ends of guide pillar 11 are to the inwall being located at respective cavities 10a.

In other embodiments, guide pillar also can be fixed in housing by other modes.

In the present embodiment, also comprise clamping part 60, blade 30 is fixedly arranged in clamping part 60, and clamping part 60 is connected with knife rest 30.Wherein clamping part 60 has slot 61 away from the side of knife rest 20, and blade 30 is inserted in slot 61, and is fixedly connected with clamping part 60 by bolt 62.

In other embodiments, also can arrange clamping part is two clamping plates, and cutting blade clip is located between two clamping plates.

In addition, with reference to Fig. 6-7, the side that housing 10 stretches out direction along blade 30 offers through hole 12, and blade 30 is extend out to outside housing 10 by through hole 12.Wherein the size of through hole 12 is can make blade 20 by being as the criterion.

Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
