As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

with reference to fig. 1, the present invention provides a razor, including a handle 100, a blade holder 200, an adjusting bracket 300, a first sliding sleeve 400 and a spring 500, wherein the handle 100 is used for holding a razor; the blade holder 200 is arranged at one end of the handle 100, and the blade holder 200 is detachably connected with the shaving blade; the adjusting bracket 300 is movably sleeved on the handle 100, and the adjusting bracket 300 is used for abutting against the razor blade to adjust the shaving angle; the first sliding sleeve 400 is movably sleeved on the knife handle 100; the moving direction of the shrapnel 500 relative to the first sliding sleeve 400 is obliquely arranged, one end of the shrapnel 500 is abutted to the handle 100, the other end of the shrapnel 500 is abutted to the adjusting frame 300, the first sliding sleeve 400 is pressed against the shrapnel 500, and the adjusting frame 300 is moved relative to the handle 100 by changing the pressing position of the first sliding sleeve 400 to the shrapnel 500.

Above-mentioned razor, the blade frame 200 of being connected can be dismantled with the razor blade sets up in the one end of handle of a knife 100, and the cover is equipped with the alignment jig 300 that can move relative to handle of a knife 100 on handle of a knife 100, and the one end and the handle of a knife 100 butt of shell fragment 500, the other end and the alignment jig 300 butt of shell fragment 500, the movably cover of first sliding sleeve 400 is established on handle of a knife 100, first sliding sleeve 400 and shell fragment 500 butt. The pressing position of the shrapnel 500 by the first sliding sleeve 400 is changed by moving the first sliding sleeve 400. When the distance between the two ends of the elastic sheet 500 in the moving direction of the first sliding sleeve 400 is increased, the elastic sheet 500 pushes the adjusting frame 300 to move towards the direction close to the blade holder 200, and the adjusting frame 300 pushes the shaving blades and changes the shaving angles of the shaving blades; when the distance between the two ends of the elastic strip 500 in the moving direction of the first sliding sleeve 400 is reduced, the shaving blade abutted against the adjusting frame 300 pushes the adjusting frame 300 to move in a direction away from the blade frame 200, and the adjusting frame 300 is abutted against the elastic strip 500, so that the shaving angle of the shaving blade is changed. Because the elastic sheet 500 is inclined relative to the moving direction of the first sliding sleeve 400, the first sliding sleeve 400 cannot push the elastic sheet 500 to move integrally relative to the tool holder 100, and only the elastic sheet 500 can push the adjusting frame 300 to move. Therefore, the moving range of the adjusting frame 300 can be controlled by controlling the pressing deformation of the elastic sheet 500 by the first sliding sleeve 400, and then the relative position of the adjusting frame 300 and the blade frame 200 is controlled, so that the condition that the shaver is damaged due to the abutting connection between the adjusting frame 300 and the blade frame 200 is avoided, and the shaving experience of a user is improved from the aspects of shaving comfort and shaving safety. In use: when the first sliding sleeve 400 moves along the handle 100 in a direction approaching the blade holder 200, one end of the elastic piece 500 abutting against the adjusting frame 300 pushes the adjusting frame 300 to move towards the blade holder 200, and the adjusting frame 300 pushes the shaving blade to change the shaving angle of the shaving blade.
