In this regard, as shown in fig. 1 to 5, the cutting tool of the present embodiment further includes an adjusting mechanism 4, and the adjusting mechanism 4 is configured to eliminate a gap between the guide projection 31 and the fitting groove 21 due to a machining error. As shown in fig. 4 and 5, the adjustment mechanism 4 includes a first operating member 41, a driving member 42, and a guide member 43.

The limiting surface 211 is one of two sidewalls of the matching groove 21 perpendicular to the second direction. In this embodiment, as shown in fig. 4, the limiting surface 211 is a sidewall on the left side of the fitting groove 21, and the guide piece 43 can guide the driving piece 42 to push the guide protrusion 31 from right to left, so that the guide protrusion 31 abuts against the limiting surface 211, and the gap between the fitting groove 21 and the guide protrusion 31 is eliminated. It is understood that in other embodiments, the limiting surface 211 can be a side wall on the right side of the engaging groove 21, and in this embodiment, the guiding element 43 can guide the driving element 42 to push the guiding protrusion 31 from left to right.

As shown in fig. 5, the bottom plate 2 is further provided with a receiving groove 22, the receiving groove 22 is located at the right side of the matching groove 21, and the receiving groove 22 is communicated with the matching groove 21. The guide piece 43 is disposed in the receiving groove 22, and during the process that the guide piece 43 guides the driving piece 42 to move in the second direction, a part of the guide piece 43 extends into the fitting groove 21, so that the guide mechanism 3 can be pushed.

As shown in fig. 2, the cutting tool includes a plurality of adjusting mechanisms 4, and the plurality of adjusting mechanisms 4 are arranged at intervals along the cutting direction, so that the gap between the guiding mechanism 3 and the matching groove 21 along the cutting direction can be eliminated, thereby further improving the guiding precision of the guiding mechanism 3 to the bottom plate 2 and the cutting mechanism 1, and improving the cutting precision of the cutting mechanism 1.

When the first operating member 41 drives the driving member 42 to move along the first direction, the driving member 42 slides along the first guiding inclined surface 521 to displace along the second direction, so as to push the guiding mechanism 3 along the second direction. In one embodiment, the driving member 42 is provided with a second guiding inclined surface 421, and the second guiding inclined surface 421 abuts against the second guiding inclined surface 421 and can slide along the second guiding inclined surface 421. The surface-to-surface fit between the first guiding inclined surface 431 and the second guiding inclined surface 421 improves the reliability of the guiding direction of the driving member 42 by the guiding member 43, and also improves the smoothness of the movement of the driving member 42.

In order to drive the driving member 42 by the first operating member 41 along the first direction, as shown in fig. 4 and 5, the guide member 43 or the bottom plate 2 is provided with a threaded hole 432 extending along the first direction, and the first operating member 41 presses the driving member 42 along the first direction and is threaded into the threaded hole 432. When the first operating member 41 is rotated, the first operating member 41 generates a first direction position, and the driving member 42 is pushed to move along the first direction. In this embodiment, the threaded hole 432 is disposed on the guide member 43, and optionally, the threaded hole 432 may be a blind hole or a through hole, which is not limited herein.

Alternatively, the first operating member 41 can be a hand screw, which is an existing standard member and can be purchased directly for use, and the cost is low.

As shown in fig. 4 and 5, an avoiding groove 413 is formed on a side of the pressing portion 412 facing the guide member 43, and a portion of the guide member 43 can extend into the avoiding groove 413, so that position interference between the first operating member 41 and the guide member 43 during movement of the first operating member in the first direction can be avoided. It is understood that, in different usage scenarios, the guide member 43 may partially extend into the avoiding groove 413, or may not extend into the avoiding groove 413 at all, and is not limited herein.

In other embodiments, the first operating member 41 may also be a cam structure located in the X-Y plane, and when the first operating member 41 is rotated, the first operating member 41 is displaced along the first direction, so as to drive the driving member 42 to move along the first direction. It will be understood that the structure of the first operating member 41 can be adjusted by those skilled in the art according to actual needs, as long as the driving member 42 can be driven to move along the first direction, and the structure is not limited herein.

In some usage scenarios, the length of the cutting mechanism 1 to be cut is very long and is greater than the length of the guide mechanisms 3, and at this time, two or more guide mechanisms 3 need to be connected for use, and due to the existence of manufacturing errors of the guide mechanisms 3, a step difference is generated at the connecting surface after the adjacent guide mechanisms 3 are connected, so that the bottom plate 2 is blocked when moving to the connecting position of the two guide mechanisms 3, and the cutting precision is further affected.

In this regard, as shown in fig. 1, the guide accessory of the present embodiment further includes a connecting mechanism 5, and the connecting mechanism 5 can connect at least two guide mechanisms 3 and avoid the problem of a step difference between adjacent guide mechanisms 3.

When the connecting member 51 moves along the first direction, the connecting member 51 will uniformly press against the two opposite slot walls of the connecting slot 311, so that the deformation of the two slot walls along the second direction is consistent, and the position of the vertical plane after the width of the guiding protrusion 31 is increased is not changed, thereby ensuring the matching precision of the guiding protrusion 31 and the matching slot 21 on the bottom plate 2, and ensuring the cutting precision of the cutting mechanism 1.
