Preferably, the locking bolt 3 is vertically arranged with the positioning pin 4, so as to realize the axial and circumferential positioning of the tool rod 5.

[0029] The present application can be used for processing the inner hole and outer circle of rotating parts. By rotating the processed parts, the tool handle 1 is installed in the boring tool holder of the set tool position, the plane of the tool neck 2 is axially aligned with the tool holder, and the plane on the upper part of the tool handle 1 is used for positioning and locking, and then the required tool bar 5 is axially installed in the tool neck 2 and the positioning pin 4 is used to fix the rotation direction and axial movement, and finally the locking bolt 3 is screwed in to lock the tool bar 5 to complete the installation of the tool. When the tool bar 5 is replaced next time, only the locking bolt 3 needs to be loosened to install the new tool bar 5. The mechanism is simple and convenient to operate, has high positioning accuracy, and is very rigid, saving time and effort, and greatly improving the processing efficiency.

[0030] The tool handle 1 is a frustum with a radial top chamfered structure, and is used for circumferential positioning and locking when installed in a tool holder.

[0031] The knife neck 2 is a semi-conical structure with a chamfered edge. The small diameter end of the knife neck 2 is connected to the knife handle 1, and the large diameter end of the knife neck 2 is provided with a locking bolt hole that cooperates with the locking bolt 3.
