The rotating seat in the utility model is installed in the tool holder front section by casting, and is no longer fixed by additional mounting parts, which increases the overall strength and integrity, and the tool holder body can swing around the rotating seat with a small amplitude of ≤10 degrees. The tool holder body in the utility model is integrally formed by casting, and a flexible connection can be achieved through the adapter seat.

[0006] Preferably, the rotating seat is rotatably mounted on the front section of the tool holder via a rotating shaft, the rotating shaft and the front section of the tool holder are integrally cast, and the rotating seat is cast inside the front section of the tool holder. The rotating shaft in the utility model is an integral casting on the front section of the tool holder, and the rotating seat is also rotatably mounted on the front section of the tool holder via a casting and rotatably connected to the rotating shaft, so that the traditional two-body structure is transformed into an integrated structure, making the tool holder frame structure more consistent, and increasing the service life and structural strength.

[0007] Preferably, the adapter ring of the rotating seat is integrally formed with a plurality of positioning protrusions. The number of positioning protrusions on the rotating seat can be adjusted according to demand. The utility model is described by taking two positioning protrusions as an example. The two positioning protrusions are conical structures and are integrally cast with the adapter ring, which is easy to assemble and has high structural strength and more stable operation.

[0008] Preferably, a micro-rotation cavity is provided in the middle section of the tool holder, and the tool body seat is rotatably installed in the micro-rotation cavity. A micro-rotation cavity is provided in the middle section of the tool holder, and a spring can be installed in the micro-rotation cavity according to needs, which can ensure that the scraper can drive the tool body seat to rotate ±8 degrees in the micro-rotation cavity during operation, thereby achieving a certain degree of flexible installation.

[0009] Preferably, the scraper is fixed on the blade seat by a fastening bolt, and the fastening bolt and the blade seat are interference fit. The scraper is fixedly installed on the blade seat by a fastening bolt, and the fastening bolt, the blade seat and the scraper are interference fit. When the scraper is damaged, it can be disassembled for maintenance, and the stability of the scraper fixation can be ensured.

[0010] Preferably, the rear section of the tool holder is integrally formed with a lever extending obliquely. The lever of the rear section of the tool holder is formed on the rear section of the tool holder by casting, thereby ensuring the overall strength and stability.

[0011] Preferably, the bottom surface of the tool holder body is integrally cast with a hollow cavity. The hollow cavity on the bottom surface of the tool holder body is formed by casting, which can reduce the volume of the tool holder body on the one hand and facilitate assembly on the other hand.

[0012] Therefore, the integrated tool holder frame structure of the present invention has the following advantages: the structure of the tool holder frame is unified and is formed by casting, the rotating seat and the tool body seat can achieve a flexible connection in two positions, the overall structure is light and has a long service life and stable operation.
