Abstract
The utility model relates to a barycenter-variable knife. The barycenter-variable knife is characterized in that a groove penetrating the surface of the knife is formed in the middle of the knife along the length direction of the knife, a bearing capable of rolling back and forth along the groove is embedded in the groove, the bearing can be a ball, and the groove can be designed to be externally-arranged equipment screwed on the knife by utilizing screws.
Description
Technical field
The utility model relates to relates to a kind of cutter that changes center of gravity.
Background technology
The center of gravity of present cutter is fixed, so must very exert oneself to build up speed while cutting hard thing.If can invent a kind of cutter that changes center of gravity, under center of gravity is moved to front while splitting can be with the hard thing of riving of power still less.
Utility model content
The purpose of this utility model is achieved in that a kind of cutter that changes center of gravity, it is characterized in that along tool length direction, offering the groove that penetrates tool surface in the middle of cutter, and in groove, being inlaid with can be along the bearing of groove scroll forward and backward.
Further, described bearing can be ball.
Further, described groove can be designed as and utilizes screw to be screwed in the external device on described cutter.
Further, described groove can set gradually from top to bottom a plurality of in the middle of cutter.
Adopt after this programme, while splitting under cutter, the bearing in box, ball can be because inertia move to cutter front end, and now the gravity motion of whole cutter is to front end.Split under power and cutter under same and split under speed, according to P=mv, the momentum of cutter front end has strengthened, and has strengthened splitting the effect of hard thing.
Accompanying drawing explanation
Fig. 1 is the structure chart of embodiment 1.
Fig. 2 is the structure chart of embodiment 2.
The specific embodiment
Specific works mode is as follows:
Embodiment 1:
As Fig. 1, a kind of cutter that changes center of gravity offers along cutter 1 length direction the groove 2 that penetrates cutter 1 surface in the middle of cutter 1, and in groove 2, being inlaid with can be along bearing or the ball 3 of groove 2 scroll forward and backwards.Described groove 2 can be designed as with screw and is screwed on the hole of cutter 1 corresponding position.
Embodiment 1:
As Fig. 2, described groove 2 can set gradually from top to bottom a plurality of in the middle of cutter 1.
Adopt after this programme, when cutter is split for 1 time, groove 2 inner bearings, ball 3 can be because inertia move to cutter 1 front end, and now the gravity motion of whole cutter 1 is to front end.Split power under same and cutter is split for 1 time under speed, according to P=mv, the momentum of cutter 1 front end has strengthened, and has strengthened splitting the effect of hard thing.
