Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

The utility model provides a cutter splines structure, including cutter upper portion 1, cutter lower part 2, cutter upper portion 1 is close to evenly be equipped with equidistant distribution's recess 5 on the 2 one end inner walls in cutter lower part, be equipped with the knife rest 4 of placing blade 3 in cutter upper portion 1, 4 below the knife rest be located set up cutter in the cutter lower part 2 and spline mechanism 6, spline mechanism 6 including pressing splenium 61, locking portion 62.

The size and shape of the grooves 5 are matched with the locking part 62, and a convex rib 11 is arranged between two adjacent grooves 5.

The embodiment of the utility model provides an in, rotatory cutter lower part 2 is in order to realize the flexible of blade 3, when adjusting required length, presses splenium 61 down, presses splenium 61 to exert pressure to locking portion 62 for locking portion 62 produces the displacement, makes locking portion 62 and 1 joint in cutter upper portion be in the same place, and cutter lower part 2 can not rotate this moment, realizes the locking purpose, uses more safely.

Optionally, the locking portion 62 includes a support 621, a sleeve 622, and a spring 623, the sleeve 622 is sleeved on the support 621, the outer wall of the sleeve 622 is fixedly provided with a protrusion 7, one end of the support 621 departing from the knife holder 4 abuts against the spring 623, and the other end of the spring 623 abuts against the pressing portion 61.

The number of the protruding parts 7 is two or more, the protruding parts 7 are fixed on the outer wall of the sleeve 622 near one end of the knife holder 4, and the spring 623 enables the supporting part 621 to abut against the knife holder 4.

Optionally, the sleeve 622 is sleeved with the cutter lower portion 2, and the cutter lower portion 2 is provided with a side groove 8 matched with the protruding member 7.

The number of the side grooves 8 is two or more, the number of the side grooves 8 is the same as that of the protruding pieces 7, and the side grooves 8 may be oval, rectangular, square, or the like.

Optionally, the end of the support 621 facing away from the blade holder 4 is provided with an inward slope 9.

Wherein, the inward inclined surface 9 is a smooth inclined surface, the angle between the smooth inclined surface 9 and the inner wall of the sleeve 622 can be 30-60 degrees, and preferably, the angle between the smooth inclined surface 9 and the inner wall of the sleeve 622 is 30 degrees.

Thus, when the sleeve 622 sleeved on the smooth inclined surface 9 is subjected to an external pressing force, the sleeve 622 can sink along the direction of the inclined surface 9, and when the external force is eliminated, the sleeve 622 is restored. When the pressing part 61 is pressed to make the sleeve 622 deviate from the inclined plane 9, the locking part 62 is clamped with the upper tool part 1, and the lower tool part 2 cannot rotate, so that the locking purpose is realized.
