Compared with the prior art, the upper cutter of the embodiment can be stably connected with the upper cutter shaft for use no matter the upper cutter is rotated clockwise or counterclockwise after being sleeved on the upper cutter shaft; when the upper cutters of the embodiment are installed, the upper cutters are not required to be identified, and only after two identical upper cutters are sleeved on the same upper cutter shaft relatively, the upper cutters and the upper cutter shaft are respectively rotated to be fixed, so that the upper cutter can be used, the operation is simple and convenient, and the efficiency is improved to a certain extent.
A plurality of wrench bayonets 111 are uniformly distributed on the lateral surface of the outer end of the outer installation body 11; the wrench bayonet 111 is used for clamping a tool wrench, so that the upper cutter is convenient to detach.
The fastener 14 is disposed within the wrench bayonet 111; the flat surface in the wrench socket 111 is used to machine a threaded hole associated with the fastener 14 more simply than the outer circumferential surface of the outer mounting body 11.
The outer mounting body 11 is sleeved with the hole of the inner mounting body 12 and the inner hole of the outer mounting body 11 coaxially, so that the matching length of the fastening nail 14 and the outer mounting body 11 is ensured, and the stable connection strength between the inner mounting body 12 and the outer mounting body 11 is ensured.
