The specific embodiment

This use is novel to provide a kind of catling; Comprise upper slitter shell, following cutter shell, tool rest and cutter head; Upper slitter shell and following cutter shell are the turtle shell shape, and cutter head is rotatably connected on tool rest, cutter head can precession cutter shell in; Accomplish the function of folding retractable, upper slitter shell and following cutter shell are separately positioned on the top and bottom of said tool rest.In the utility model, cutter head can rotate on tool rest, with the cutter head rotation, can realize the function of opening and regaining of cutter head.

Below in conjunction with accompanying drawing, describe in detail.

Please refer to Fig. 1, a kind of catling, it exactly likes tortoise; This catling comprises upper slitter shell 1, following cutter shell 3, tool rest 2 and cutter head 4, and upper slitter shell 1 is identical with the shape of following cutter shell 3, and tool rest 2 is similar with the shape of upper slitter shell 1, following cutter shell 3; But also inequality, just size dimension is close.The cutter shell is provided with scraggly lines, increases the comfort level of hand, prevents that hand is sliding.

Please refer to Fig. 2 and Fig. 3; Tool rest 2 comprises upper cutter head 21 and following tool rest 22; Upper cutter head 21 is connected through afterbody is stacked with following tool rest 22, promptly can regard upper cutter head 21 and following tool rest 22 as two independent individualities, with upper cutter head 21 and following tool rest 22 overlapping placements; But upper cutter head 21 will keep certain distance with following tool rest 22, and the afterbody of the afterbody of upper cutter head 21 and following tool rest 22 linked together gets final product:

Comprise the U type groove 211 of droping to the ground on the upper cutter head 21, the opening surface of U type groove 211 is to the afterbody of upper cutter head 21, the pressure that the length of this U type groove 211 control steel ball 7 is downward, the just elastic force of steel plate.One aperture 212 is set in U type groove 211, and this aperture 212 is a through hole, is embedded a steel ball 7 in the aperture 212.

The front portion of following tool rest 22 comprises that two cut side 221, and said two cut between 22 of side 221 and the said down tool rests and have bending angle, and this structure can be regarded as; Shear respectively along dual-side from the place ahead of following tool rest 22; Do not cut dual-side, only cut certain distance and get final product, after shearing; With upwards bending of the dual-side of shearing, make two sides that were sheared have certain included angle with following tool rest 22.Have two of bending angle and cut side 221 and be used for supporting simultaneously two limits of two-way rotary cutter 4, thus locking cutter head 4.

All be provided with one on upper cutter head 21 and the following tool rest 22 is used for the through hole 213 that is connected with cutter head 4 and is used for respectively and upper slitter shell 1, the connecting hole that is connected of cutter shell 3 down at identical position; Corresponding cutter head 4 is provided with the groove 421 with through hole 213 establishings, and upper slitter shell 1 is provided with adaptive connecting hole with following cutter shell 3.Because structure is very similar all; Embodiment does not describe in detail, and be that example specifies with upper cutter head 21 with upper slitter shell 1 only: the front end of upper cutter head 21 is provided with connecting hole 1, and the two sides of tail of upper cutter head 21 is provided with connecting hole 2 215 and connecting hole 3 216; Corresponding; Upper slitter shell 1 is provided with connecting hole one by one 11, and the two sides of tail of upper slitter shell 1 is provided with connecting hole 22 12 and connecting hole 33 13, and these a little connecting holes are fastenedly connected through long spiro nail 9.Between upper cutter head 21 and following tool rest 22, two support sets 8 are set, this support set 8 and the coaxial installation of the connecting hole of tool rest rear end.

Please refer to Fig. 4 and Fig. 5, cutter head 4 comprises blade end 41 and link 42, and blade end 41 is a use side, and link 42 plays the effect that is connected of cutter head 4 and tool rest 2.Please refer to Fig. 6 and Fig. 7, link 42 comprises two limits, and these two limits are symmetrical limit, be provided with on the link 42 one with the suitable groove 421 of through hole 213, cutter head 4 pivots through interlocking pin and is connected between upper cutter head 21 and the following tool rest 22.Interlocking pin comprises that interlocking is pinned and one 5 pins 26 with interlocking; Interlocking is pinned and 26 can be injected interlocking and pin in one 5; Play a part with cutter head 4 be installed on the tool rest 2 and cutter head 4 can upper cutter head 21 on rotation; This interlocking pin is arranged on the interior volume of upper slitter shell 1 and following cutter shell 3 compositions, and the purpose of this structure is the outward appearance that prevents to destroy the cutter shell.One circle groove 422 is set around this groove 421, and this groove 422 is blind hole, and cutter head 4 is in rotation process; These grooves 422 play interim location, simultaneously, can not let cutter head 4 too suitable sliding when rotating; Improve security, and, when cutter head 4 rotates; One grade of revolution all can send the strike note with steel ball 7, lets the clearer cutter head 4 of recognizing of people rotate.The back side on two limits of link 42 is provided with some gear grooves; In the present embodiment; 4 gear grooves are set; The both sides of cutter head 4 links 42 respectively comprise two gear grooves, these two gear grooves corresponding respectively go out the cutter shelves and return sword shelves, two gear grooves on promptly every limit comprise cutter groove 423 respectively and return sword groove 424.In the present embodiment, the afterbody of cutter head 4 links 42 also comprises a life-saving hamer 425, in the urgent moment, is used for life-saving.

The utility model exactly like tortoise, this catling has folding function, through rotary cutter 4, cutter head 4 is rotated into the jackknife action of just having accomplished cutter in the tool rest 2, in like manner, cutter head 4 is spun out the opening action of just having accomplished cutter from tool rest 2.

More than a disclosed specific embodiment that is merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
