The tool fixture can fix and remove the tool through the locking structure, and the operating position is at the lower side of the tool fixture. When cutting the product, the rotating device rotates the tool fixture to switch the tool to use, and at the same time, the cleaning structure can clean and blow the tool to clean the impurities on the tool and keep the clean blade for cutting.

[0022] The tool fixture 1 described in the utility model includes a center column 11 and clamping plates 12 fixed to the upper and lower sides thereof. The tool is arranged outside the center column and between the two clamping plates. The tool fixture preferably adopts the currently used specifications. The center column and the upper and lower clamping plates are all square. A tool can be installed on each side, and a total of 4 tools can be installed. If necessary, other tool fixtures that can install more tools can be replaced.

The threaded top column is screwed into the hole on the clamping plate by threading until the threaded top column presses the tool tightly, and then the nut is screwed into the threaded top column by threading until it is close to the clamping plate, so that the position of the threaded top column is fixed and will not shift, thereby pressing the tool. The top plate matching block is used to press the other side of the threaded top column position, which is in a fixed state and is used to cooperate with the threaded top column to press the tool tightly.

[0024] The upper end of the threaded top column 31 and the lower end of the top plate matching block 33 in the utility model can clamp a tool.
