Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, a cutter for producing an electrical contact convenient for replacing a blade comprises a blade 1 and a blade holder 4, the blade 1 is slidably connected to the center of the top of the blade holder 4, a rotating rod 3 is rotatably connected to the rear surface wall of the blade holder 4 and the bottom of the blade 1 through a rotating shaft, the rotating rod 3 can rotate around the blade holder 4, a through groove 8 is formed in the bottom of the rotating rod 3, push rods 7 are symmetrically arranged in the inner cavity of the blade holder 4, the top and the bottom of the push rods 7 are elastically connected through a first spring 10, the push rods 7 have buffering performance in the vertical direction through the first spring 10, slide rods 5 are welded between the inner surface walls on the two horizontal sides of the blade holder 4 and the inner surface wall close to the blade 1, a limiting shaft 11 is slidably connected to the outside of the slide rods 5, a first magnet 9 is welded at the bottom of the limiting shaft 11 close to the blade 1, and a pulling rod 2, the horizontal both sides of blade 1 all seted up the spacing hole 13 that the spacing axle of cooperation 11 made, inlay on the interior table wall in spacing hole 13 and be equipped with second magnet 14, first magnet 9 and second magnet 14 have the magnetic force of inter attraction.

Furthermore, the push rod 7 is connected with the inner surface wall of the knife rest 4 through a limiting sleeve 6, and the limiting sleeve 6 enables the push rod 7 to move only in the vertical direction to prevent the push rod from deviating.

Furthermore, one end of the pulling rod 2 penetrates through the inner surface wall of the tool rest 4 and extends to the outside of the tool rest 4, and the pulling rod 2 is pulled towards two sides to enable the limiting shaft 11 to be separated from the limiting hole 13.

Furthermore, a small hole 12 is formed in the inner surface wall of the tool rest 4 close to the blade 1, the small hole 12 and the bottom of the limiting shaft 11 are on the same horizontal line, and the limiting shaft 11 needs to penetrate through the small hole 12 when entering the limiting hole 13.
