[0024] The working principle of the present application is that: first, the core rod 31 is installed in the center hole 25, and the through slot 313 needs to be aligned with the triangular slot 26, and the angle and height need to be aligned, so this operation usually needs to be operated with the help of a threaded sleeve, a threaded sleeve matched with the screw rod 311 is customized, the threaded sleeve is tightened with the screw rod 311, the threaded sleeve is held to install the core rod 31 into the center hole 25, the angle and height are aligned, the inner end of the pressing plate 32 is arranged from the triangular slot 26 into the through slot 313, the pin is installed into the hinge hole 27 and connected with the hinge lug 321, after the installation of all the pressing plates 32 is completed, the threaded sleeve can be removed, at this time, the core rod 31 will fall down under the influence of gravity, and correspondingly, the inner end of the pressing plate 32 is turned down and the outer end is turned up. At this time, the tool bit 10 can be installed on the inner core 23 from top to bottom, when the threaded cylinder 15 contacts with the screw rod 311, the tool bit 10 is rotated, so that the threaded cylinder 15 and the screw rod 311 are tightened with each other, since the position between the tool bit 10 and the tool holder 20 is limited by the mounting seat 12 and the mounting groove 22, during the tightening process of the threaded cylinder 14 and the screw rod 311, the threaded cylinder 15 pulls up the screw rod 311, during the pulling up process of the screw rod 311, the core rod 31 drives the pressing plate 32 to turn over, and the outer end thereof is turned down, until the outer end of the pressing plate 32 is pressed against the clamping boss 14, until the threaded cylinder 15 and the screw rod 311 are tightened with each other, the pressing head 322 of the pressing plate 32 is pressed against the clamping boss 14, and the pressing of the tool bit 10 and the tool holder 20 is completed. Of course, the specific sizes of the internal components need to be designed in coordination with each other. At this time, the height of the core rod 31 in the center hole 25 is determined, and at this time, the through hole 314 corresponds to the position of the positioning hole 28, and the height position of the core rod 31 is locked by inserting the pin. After the height position of the core rod 31 is locked, the pressing plate 32 presses the clamping boss 14, and the threaded cylinder 15 and the screw rod 311 cannot continue to rotate with each other. The installation, positioning and locking of the tool bit and the tool holder are completed. The disassembly of the device is also relatively simple, the pin in the through hole 314 is removed, and the tool bit 10 is rotated in the opposite direction to complete the disassembly.
