When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figure 1-3 , a tool quick replacement device for a solid wood cutting machine comprises a tool handle 1, a docking port 11 is provided at the upper end of the tool handle 1, the docking port 11 is connected to the CNC milling machine transmission, the outer ring of the lower end of the tool handle 1 is threadedly connected to the inner ring of the tool cap 2, the outer ring of the upper end of the tool cap 2 is a hexagonal structure, and the hexagonal structure is convenient for an operator to use a tool to rotate the tool cap 2, and the inner ring of the tool handle 1 is annularly arranged with multiple tool clamps 21, and the tool clamp 21 is in contact with the upper end of the tool through one end of the inner ring of the tool handle 1 and the inner ring of the tool cap 2 is in contact with the inclined surface provided at the lower end of the tool clamp 21. By inserting the tool into the inner rings of the multiple tool clamps 21 arranged in an annular manner, and then using the tool to rotate the upper end of the tool cap, the inner ring of the tool cap 2 can drive the tool clamp 21 to move toward the upper end of the tool, so that the tool cap 2 is screwed and tightened to fix the tool, and it can also be suitable for tools of different sizes.

[0022] The inner ring of the lower end of the knife cap 2 is provided with an inclined surface parallel to the inclined surface of the lower end of the knife clamp 21. The inclined surfaces are parallel, so that the contact surface between the inner ring of the lower end of the knife cap 2 and the knife clamp 21 becomes larger, thereby avoiding damage to the inner ring of the knife cap 2 when fastening the knife.
