[0007] Preferably, the drill bit replacement assembly includes a clamping block fixedly mounted on one side of the drill bit, the clamping block is provided with a clamping slot consisting of a circular slot and a triangular slot, and a connecting rod for inserting into the clamping slot is installed at the bottom of the turntable.

[0008] Preferably, the positioning assembly comprises a rotating plate mounted on the top of the rotating rod, a positioning slot is formed on the rotating plate, and a rotating block for inserting into the positioning slot is connected to the top of the workbench via a torsion spring shaft.

[0009] Preferably, a handle is installed on the top of the rotating plate to facilitate the staff to rotate the rotating rod.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] In the present application, when it is necessary to replace drill bits of different specifications, the staff first grasps the rotating block and rotates it, and the rotating block will disengage from the positioning slot. Then the staff grasps the handle to make the rotating plate drive the rotating rod to rotate, and the rotating rod will drive the turntable to rotate the drill bit. In this way, the staff can rotate the appropriate drill bit to the bottom of the lifting rod, and then the staff can release the rotating block, and the rotating block will be reset through the torsion spring shaft and reinserted into the positioning slot, so that the staff can easily replace the drill bit.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] Embodiment 1:

[0020] like Figure 1-3As shown, a punching device for carton and paperboard production comprises a workbench 1, on which is provided a drill bit 2 for punching paperboard, on which is installed a lifting rod 3 for driving the drill bit 2 to move, a limit block 4 for inserting into the lifting rod 3 is installed on the top of the drill bit 2, the limit block 4 is arranged in a T shape, and the limit block 4 is arranged in an arc shape as a whole, so that the limit block 4 can be just inserted into the interior of the lifting rod 3 after rotation, the outer wall of the drill bit 2 is slidably connected with a turntable 5 for driving the drill bit 2 to rotate, the number of drill bits 2 is set to be multiple, and the multiple drill bits 2 are arranged in a ring shape and equidistantly on the turntable 5 in sequence, and the specifications of the multiple drill bits 2 are different, a rotating rod 9 for driving the turntable 5 to rotate is installed on the workbench 1, a positioning component for fixing the rotating rod 9 is installed on the workbench 1, and a drill bit replacement component for replacing the drill bit 2 is installed on the turntable 5.

[0021] Embodiment 2:

[0022] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the drill bit replacement assembly includes a block 6 fixedly mounted on one side of the drill bit 2, a slot 7 is formed on the block 6, and the slot 7 consists of a circular slot and a triangular slot. A connecting rod 8 for inserting into the slot 7 is installed at the bottom of the turntable 5.

[0023] Embodiment three:

[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 1 As shown, the positioning assembly includes a rotating plate 10 installed on the top of the rotating rod 9, a positioning groove 11 is opened on the rotating plate 10, a rotating block 12 for inserting into the positioning groove 11 is connected to the top of the workbench 1 through a torsion spring shaft, and a handle 13 is installed on the top of the rotating plate 10 for facilitating the staff to rotate the rotating rod 9.
