Abstract
The utility model relates to a spiral propelling cutting knife used for cutting various thin plates, such as ternary plates, organic glass plates and the like. The spiral propelling cutting knife adopts the following structure: a hilt upper piece and a hilt lower piece are connected into a whole body to form a hilt; a horizontal propelling screw is arranged in the hilt upper piece; a driving gear is fixedly connected with the right end of the horizontal propelling screw; a strip hole is arranged on the hilt; a push button is arranged in the strip hole; and the inner end of the push button is inserted in the thread groove of the horizontal propelling screw; a rotating screw is arranged in the hilt lower piece; a driving gear is fixedly connected with the right end of the rotating screw, and the driving gear is connected with the driving gear; slinging grooves are arranged in the hilt upper piece and the hilt lower piece; blade frames are erected in the slinging grooves to ensure the blade frames to be positioned between the horizontal propelling screw and the rotating screw; blades are arranged on the upper surface of the blade frames; thread grooves are arranged on the lower surface of the blade frames, and the thread grooves are pressed on the rotating screw. Because the spiral propelling is realized through rotating, the friction is greatly reduced, and the service life of the cutting knife is prolonged.
Description
Technical field
The utility model is a kind of cutter that are used to cut various thin plates such as three-ply board poly (methyl methacrylate) plate etc., particularly a kind of screw propulsion cutter.
Background technology
Existing cutter, its cutting knife all are telescopic, and cutting knife is to be placed in the sliding tray, and cutting knife is provided with a push button, realize the flexible of cutting knife by promoting push button.Stretch mode so, the one, frictional force is too big, boosts very hard, uses inconvenience; The 2nd, do not push away several times, push button is just bad, causes whole cutter to be scrapped.
Summary of the invention
The purpose of this utility model is in order to overcome the defective that existing cutter use inconvenience to damage easily, invent a kind ofly to realize the screw propulsion cutter that cutting knife stretches by twin-screw.
The purpose of this utility model realizes as follows: described screw propulsion cutter, comprise sheet and blade holder under hilt last slice, the hilt, and sheet is connected in one by screw and constitutes hilt under hilt last slice and the hilt; Be provided with the horizontal sliding screw rod in the hilt last slice, the right-hand member of horizontal sliding screw rod is connected with driving gear, and hilt last slice has strip hole, is provided with push button in the strip hole, and the inner of push button is inserted in the horizontal sliding screw flight ditch; Be provided with rotary screw under the hilt in the sheet, the right-hand member of rotary screw is connected with driven gear, and driven gear is connected with driving gear; Be provided with sliding tray in the sheet under hilt last slice and the hilt, blade holder is located in the sliding tray, makes blade holder between horizontal sliding screw rod and rotary screw, and the upper surface of blade holder is provided with blade, and the lower surface of blade holder is provided with thread groove, and thread groove is pressed on the rotary screw.
The lower surface of described blade holder is provided with flexure strip, and flexure strip is provided with grab and head; Blade is located at the upper surface of blade holder, and is stuck on the grab; On hilt last slice, be provided with button, when blade holder slides into high order end, button just in time with head to contacting.
The right-hand member of described hilt last slice is provided with flexible door, and the flexible door left end is connected on the hilt last slice by spring shaft, and the flexible door right-hand member is connected on the hilt last slice by door knob, is between the storage of spare blade in the flexible door.
Good effect of the present utility model is as follows: owing to be to realize the screw propulsion of cutter with the rotation of horizontal sliding screw rod and rotary screw, use both laborsaving, convenient again; Because screw propulsion is realized by rotating, so reduced friction greatly, has improved the service life of cutter.
