in operation, when the tool body 1 and the holder 2 are to be disconnected from each other, the knob 38 is rotated to drive the cam 36 to rotate through the connecting shaft 37, so that the cam 36 pushes up the tool body 1, the stopper 34 moves synchronously with the movement of the tool body 1 and is released from the engagement with the insert 32 by being pressed by the insert 32, and then the tool body 1 is pulled away from the holder 2 to release the connection between the tool body 1 and the holder 2 from the connecting groove 31.

One side of the torsion spring 39 close to the knob 38 is fixedly connected with the knob 38, and one side of the torsion spring 39 far from the knob 38 is fixedly connected with the outer side of the tool apron 2;

during operation, when the knob 38 rotates, the torsion spring 39 fixedly connected with the knob 38 is twisted synchronously to generate elastic deformation, and when the knob 38 stops rotating, the knob 38 automatically returns to the original position under the action of the reducing force of the torsion spring 39 and drives the cam 36 to also return to the original position through the connecting shaft 37.

A rubber sleeve is sleeved on the outer side of the knob 38, and anti-skid lines are arranged on the outer side of the rubber sleeve;

when the anti-slip knob is in operation, the rubber sleeve is sleeved on the outer side of the knob 38, and the anti-slip threads are arranged to increase friction force so as to prevent the knob 38 from slipping due to too small friction force when the knob is rotated.

An auxiliary connecting mechanism is arranged between the bottom end of the cutter main body 1 and the connecting groove 31 and comprises a clamping block 51, a clamping groove 52, an extrusion seat 53 and a return spring 54, the clamping block 51 is fixedly connected to the center of the bottom end of the connecting groove 31, the clamping block 51 is inserted into the clamping groove 52, the clamping groove 52 is formed in the bottom end of the cutter main body 1, the extrusion seats 53 are fixedly connected to two sides of the inner wall of the clamping block 51, and the return spring 54 is arranged between the two groups of extrusion seats 53;

when the tool body 1 is inserted into the connecting groove 31, the clamping block 51 is also synchronously inserted into the clamping groove 52 and is extruded by the inner wall of the clamping groove 52 to generate elastic deformation, the clamping groove 52 is made of plastic, so that the clamping groove 52 can generate small elastic deformation when being extruded, the two sides of the clamping block 51 move towards the central position due to being extruded, the extrusion seat 53 is driven to extrude the return spring 54, the return spring 54 generates elastic deformation, when the tool body 1 is completely inserted into the connecting groove 31, the extrusion force of the inner wall of the clamping groove 52 to the clamping block 51 disappears, the clamping block 51 recovers to be in an original shape under the combined action of the reducing force of the return spring 54 and is clamped with the clamping groove 52, and the effect of assisting in fixing the connection between the tool body 1 and the tool apron 2 is achieved, the opposite is true when the connection between the tool body 1 and the holder 2 is to be released.

Example two

Referring to fig. 5, in a first comparative example, as another embodiment of the present invention, a clamping block 41 is fixedly connected to a position of the bottom end of the tool main body 1 near to two sides, and the clamping block 41 is clamped with a clamping groove 42, and the clamping block 41 is made of rubber; during operation, when the tool body 1 is inserted into the inside of the connecting groove 31, the inner wall of the connecting groove 31 extrudes the fixture block 41, so that the fixture block 41 made of rubber is elastically deformed, when the tool body 1 is completely inserted into the inside of the connecting groove 31, the extrusion force of the inner wall of the connecting groove 31 on the fixture block 41 disappears, at this time, the fixture block 41 is restored to the original state under the action of the self restoring force and is clamped with the clamping groove 42, the effect of further fixing the connection between the tool body 1 and the tool holder 2 is achieved, and the reverse effect is achieved when the connection between the tool body 1 and the tool holder 20 is released.

The working principle is as follows: when the tool body 1 is inserted into the connecting groove 31, the insertion block 32 is also synchronously inserted into the slot 33, when the insertion block 32 is inserted into the slot 33, the insertion block 32 extrudes the limiting block 34 adhered to the inner wall of the slot 33, so that the limiting block 34 elastically deforms, when the tool body 1 is completely inserted into the connecting groove 31, the extrusion force of the slot 33 on the limiting block 34 disappears, at this time, the limiting block 34 automatically restores to the original position under the action of the self restoring force and is clamped with the insertion block 32, so that the insertion block 32 is limited, and the tool body 1 is connected with the tool apron 2.

When the connection between the tool body 1 and the tool post 2 is to be released, firstly, the knob 38 is rotated to drive the cam 36 to rotate through the connecting shaft 37, so that the cam 36 jacks up the tool body 1, the limiting block 34 also moves synchronously with the movement of the tool body 1 and releases the clamping with the inserting block 32 due to the extrusion of the inserting block 32, then the tool body 1 is pulled in the direction away from the tool post 2 to pull out the tool body 1 from the connecting groove 31 to release the connection between the tool body 1 and the tool post 2, when the knob 38 rotates, the torsion spring 39 fixedly connected with the knob 38 is synchronously twisted to generate elastic deformation, and when the knob 38 stops rotating, the knob 38 automatically returns to the original position under the restoring force of the torsion spring 39 and drives the cam 36 to return to the original position through the connecting shaft 37.

When the tool body 1 is inserted into the inside of the coupling groove 31, the catching block 51 is also inserted into the inside of the catching groove 52 simultaneously, and is pressed by the inner wall of the clamping groove 52 to generate elastic deformation, the clamping groove 52 can generate smaller elastic deformation when being pressed because the clamping groove 52 is made of plastic, the two sides of the clamping block 51 move to the central position because of being pressed to drive the pressing base 53 to press the return spring 54, so that the return spring 54 generates elastic deformation, when the tool body 1 is completely inserted into the connecting groove 31, the pressing force of the inner wall of the engaging groove 52 against the engaging block 51 disappears, and the engaging block 51 returns to its original shape under the combined action of its own restoring force and the restoring force of the restoring spring 54 and engages with the engaging groove 52, thereby assisting the fixing of the connection between the tool body 1 and the holder 2, and vice versa when the connection between the tool body 1 and the holder 2 is to be released.
