The sawing angle adjusting device comprises an eccentric group 4, a pressing member 5, a linkage group, and a rotating group 7. The eccentric group 4 has a shaft seat 41 fixed to the bottom surface of the base 3 and adjacent to the ring edge 311, and an eccentric member 42 pivotally mounted on the shaft seat 41. The shaft seat 41 has a shaft hole 411. The eccentric member 42 is rotatably disposed in the shaft hole 411 of the shaft seat 41, and has a thick portion 421 and a thin portion 422 defining an eccentric hole 42 ,, and the thick portion The 421 is connected and passes through a post 423 of the axle seat 41. The pressing member 5 is an arc groove 321 passing through the swing arm 32 in a direction parallel to the axis, a ring edge 311 of the base 31, the shaft seat 41 and the eccentric member 42 and having abutting against the swing arm 32. a first end portion 51, a second end portion 52 opposite to the first end portion 51, and a convex portion 53 formed on the second end portion 52. The convex portion 53 is disposed at the eccentric member 42. Inside the eccentric hole 420. The interlocking group 6 has a first link 61, a second link 62, a third link 63, and a driving member 64. The first link 61 is disposed on the bottom surface of the base 31 so as to be displaceable in a direction parallel to the axis. The second link 62 is a post 423 pivotally connected to the end of the first link 61 and the eccentric 42. The 201132432 two-link 63 is pivotally connected to the first third link 63 with the same 丄=2. The driving member 64 is externally and has _ in the housing, referring to FIG. 4 and FIG. 7', the rotating group 7 has a rack 71 disposed under the swing arm 32: a portion: 20 A rotating rod 72 of the base 3i and the J-rotating rod 72 form a gear that interlocks with the rack 71. 64Γ1, FIG. 5' and FIG. 6' when the user moves the drive member link 63 upward in the direction parallel to the axis X, and pushes the second::: the axis X toward the eccentric The direction of the 42 is displaced. At this time, the second link 62 that is synchronously pushed converts the linear displacement into the amount of rotation by the pivotal relationship with the first link Η and the eccentric 42 of the eccentric 42. Since the eccentric member 42 is restrained in the shaft hole 4 ι of the shaft seat 41, it is rotated in the counterclockwise direction in the shaft hole 411 of the shaft seat 41, so that the eccentric portion 42 is formed by the thin portion 422. It is placed between the convex portion 53 of the pressing member 5 and the rim 3 11 of the base 31. Referring to FIG. 3, FIG. 4, and FIG. 6, due to the thickness (four)' of the thin portion of the eccentric member, there is a space between the convex portion 53 of the pressing member 5 and the rim of the base 31. 5 The gap of the movement, so the pressing member 5 will be loose. _ 4, Fig. 7 'By this, only the swing arm 32 can be moved, so that the swing arm 32 can be centered, and (10)_ can be rotated according to the pressing member 4 to adjust the ore angle of the ore piece 33 the goal of.
