As a further description of the above technical solution:
the limiting mechanism comprises four limiting teeth which are rotationally connected to one end of the mounting ring, one end, close to the milling cutter seat, of the mounting ring is connected with a mounting block, and an elastic piece is connected between the mounting block and the limiting teeth.
As a further description of the above technical solution:
the elastic piece is a spring piece.
As a further description of the above technical solution:
the four limiting teeth are uniformly connected to one end of the mounting ring.
As a further description of the above technical solution:
the mounting mechanism comprises a thread groove formed in the side wall of the knob, a limiting hole is formed in the side wall of the mounting ring, and the thread groove is fixed with the limiting hole through a bolt.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
1. according to the utility model, the mounting ring is mounted on the side wall of the knob through the mounting mechanism when the milling cutter is used, the milling cutter is screwed through the knob, the screwing between the limiting mechanism and the ratchet wheel is not affected, and when the ratchet wheel and the limiting mechanism are clamped during reverse rotation, the milling cutter is prevented from falling due to loosening of the knob.
2. In the utility model, when the ratchet wheel rotates anticlockwise, the limiting teeth rotate when contacting the ratchet wheel, the rotation is not influenced, and when the ratchet wheel rotates clockwise, the limiting teeth are clamped with the ratchet wheel, so that the rotation is avoided. The spring piece can play the effect of fixed spacing tooth position on the one hand, and on the other hand can realize spacing tooth's reset.
3. In the utility model, the plurality of limiting teeth can facilitate the limiting effect with the ratchet wheel. Through screw groove and spacing hole through bolt fastening, dismantle the collar, unscrew milling cutter through the knob, be convenient for realize the installation and the dismantlement to milling cutter.
