the during operation, when spliced pole 31 is inserting the inside to blade holder 2, locating piece 38 also synchronous insertion to the inside of constant head tank 39, the effect through the combination of locating piece 38 and constant head tank 39 plays the effect of fixing a position spliced pole 31, locating piece 38 can produce when spliced pole 31 male angle is incorrect and block spliced pole 31, make spliced pole 31 can't insert the inside to blade holder 2 completely, play and prevent that spliced pole 31 from inserting the angle and producing wrong effect.

A release mechanism is arranged on one side of the tool apron 2, the release mechanism comprises a butt joint groove 51, a butt joint block 52, a movable block 53, a movable groove 54 and an extrusion spring 55, the butt joint groove 51 is arranged at a position close to the center of the bottom end of the sleeve block 35, the butt joint block 52 is slidably connected to one side of the tool apron 2, the movable block 53 is fixedly connected with the tool apron 2, the movable block 53 is slidably connected to the inside of the movable groove 54, the movable groove 54 is arranged on one side of the butt joint block 52 close to the tool apron 2, and the extrusion spring 55 is arranged inside the movable groove 54;

in operation, when the connection between the cutting head 1 and the holder 2 is to be released, the abutment block 52 is first pushed upwards, under the action of thrust, the abutting block 52 moves and extrudes the abutting groove 51, so that the sleeve block 35 moves and drives the limiting block 33 to move synchronously through the connecting plate 34, when the abutting block 52 is pushed to the limit, the sleeve block 35 also moves to the limit to drive the limiting block 33 to completely remove the clamping with the limiting groove 32, the limiting on the connecting column 31 is removed, at the moment, the connection between the tool bit 1 and the tool apron 2 is removed, the tool bit 1 can be taken down by pulling the tool bit 1 upwards, when the abutting block 52 moves, the movable block 53 also slides inside the movable groove 54 in synchronization with the movement of the abutting block 52, and presses the pressing spring 55, elastically deforming the pressing spring 55, the abutment block 52 automatically returns to the original position by the reducing force of the pressing spring 55 when the pushing of the abutment block 52 is stopped.

A friction pad 56 is glued on one side of the abutting block 52 away from the tool apron 2, and the friction pad 56 is made of rubber;

in operation, the friction pad 56 made of rubber material has the effect of increasing the friction between the finger and the abutment block 52 when pushing the abutment block 52, thereby preventing slippage when pushing the abutment block 52.

Example two

Referring to fig. 4, in a first comparative example, as another implementation manner of the present invention, a clamping block 43 is glued and adhered to an inner wall of the positioning slot 39, the clamping block 43 is clamped with a clamping groove 44, the clamping groove 44 is formed on one side of the positioning block 38, and the clamping block 43 is made of rubber; during operation, the locating piece 38 extrudes the fixture block 43 made of rubber when being inserted into the locating groove 39, so that the fixture block 43 elastically deforms, the extrusion force of the locating piece 38 on the fixture block 43 disappears when the locating piece 38 is completely inserted into the locating groove 39, and the fixture block 43 automatically restores to the original state under the action of the self restoring force and is clamped with the clamping groove 44, so that the auxiliary fixing of the connecting column 31 is realized, and the auxiliary connection effect is realized between the tool setting head 1 and the tool apron 2.

The working principle is as follows: when will be connected between tool bit 1 and the blade holder 2, insert the inside on blade holder 2 top with spliced pole 31 at first, spliced pole 31 produces the extrusion to the inclined plane that stopper 33 top was seted up when spliced pole 31 inserts the inside to blade holder 2, make stopper 33 produce to remove and drive the synchronizing of cover block 35 through connecting plate 34 and remove, make cover block 35 pulling reset spring 37 produce elastic deformation, spliced pole 31 disappears to stopper 33's extrusion force when inserting spliced pole 31 completely inside blade holder 2, cover block 35 resumes to the normal position and drives stopper 33 through connecting plate 34 and also resume to the normal position under the effect of reset spring 37's reducing force this moment, make stopper 33 and spacing groove 32 block, carry on spacingly to spliced pole 31, make be connected between tool bit 1 and the blade holder 2.

When the sleeve block 35 moves, the sliding block 41 slides inside the sliding groove 42 along with the movement of the sleeve block 35, and the combined action of the sliding block 41 and the sliding groove 42 reduces the friction force between the sleeve block 35 and the inner wall of the sleeve groove 36 when moving, so that the sleeve block 35 is prevented from being blocked due to the overlarge friction force between the sleeve block 35 and the inner wall of the sleeve groove 36 when moving, and the sleeve block 35 is more smooth when moving.

When spliced pole 31 is inserting the inside to blade holder 2, locating piece 38 also synchronous insertion to the inside of constant head tank 39, the effect through the combination of locating piece 38 and constant head tank 39 plays the effect of fixing a position spliced pole 31, locating piece 38 can produce when spliced pole 31 male angle is incorrect and block spliced pole 31, make spliced pole 31 unable insert the inside to blade holder 2 completely, play and prevent that spliced pole 31 from inserting the effect that the angle produced the mistake.

When the connection between the cutting head 1 and the holder 2 is to be released, the abutment block 52 is first pushed upwards, under the action of thrust, the abutting block 52 moves and extrudes the abutting groove 51, so that the sleeve block 35 moves and drives the limiting block 33 to move synchronously through the connecting plate 34, when the abutting block 52 is pushed to the limit, the sleeve block 35 also moves to the limit to drive the limiting block 33 to completely remove the clamping with the limiting groove 32, the limiting on the connecting column 31 is removed, at the moment, the connection between the tool bit 1 and the tool apron 2 is removed, the tool bit 1 can be taken down by pulling the tool bit 1 upwards, when the abutting block 52 moves, the movable block 53 also slides inside the movable groove 54 in synchronization with the movement of the abutting block 52, and presses the pressing spring 55, elastically deforming the pressing spring 55, the abutment block 52 automatically returns to the original position by the reducing force of the pressing spring 55 when the pushing of the abutment block 52 is stopped.
