Detailed description of the invention

With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.

According to shown in Fig. 1 to Fig. 4, the present embodiment is that a kind of strawberry plucks dedicated scissors, include one there is blade 3 cut cover and an engagement sleeves with tool rest; Described cover of cutting includes one in order to be enclosed within soft on forefinger and to have flexible index finger cover 1, and is fixedly connected on the blade bearing 2 of index finger cover outer surface, and described blade is arranged in blade bearing movably; Described blade is steel matter, and blade two ends are connected with two guide pads 31; The overall curved plate structure of described blade bearing, blade bearing offers a blade flex seam 21 stretched out for blade along its length, the position that blade bearing is positioned at blade flex seam two ends offers guide pad installing port 23, and the position of the corresponding guide pad installing port of blade bearing outer wall is left to stop that guide pad departs from the spacing retaining wall 20 of blade bearing; The position of the corresponding blade flex seam of blade bearing inwall and guide pad installing port forms magnetic sheet and installs recess 22, magnetic sheet is installed recess internal fixtion and is bonded with the first permanent magnetism sheet 6 coordinating with blade and guide pad and suck, when the first permanent magnetism sheet and blade adhesive, the blade of blade is within blade flex seam, cuts finger to avoid blade; When the guide pad of the first permanent magnetism sheet and spacing retaining wall offset, the blade of blade stretches out blade bearing outer surface 2-4mm, the blade stretched out is in order to cut off strawberry bar, and blade and the magnetic attraction force between guide pad and the first permanent magnetism sheet are than large more than 1.0 Ns of the gravity of blade and guide pad, so no matter blade is in any angle, and blade all can suck or suck back and by the first permanent magnetism sheet; It is the guiding surface 24 tilted that described guide pad installing port and blade flex stitch relative sidewall, and the guiding surface of two guide pad installing ports is parallel to each other, the wall that described guide pad is relative with guiding surface is also parallel to each other with guiding surface, guiding surface coordinates with guide pad, makes the outwardly directed movement simultaneously producing side direction of blade be beneficial to cut off strawberry bar.
