[0031] The cam 21 is provided with a plurality of slots 21 for locking the drill chuck body 1 and the cam 22 is provided with a plurality of slots 21 for locking the drill chuck body 1. The cam 21 is provided with a plurality of slots 21 for locking the drill chuck body 1 and the cam 22 is provided with a plurality of slots 21 for locking the drill chuck body 1. The cam 21 is provided with a plurality of slots 21 for locking the drill chuck body 1 and the cam 22 is provided with a plurality of slots 21 for locking the drill chuck body 1. The cam 21 is provided with a plurality of slots 21 for locking the drill chuck body 1 and the cam 22 is provided with a plurality of slots 21 for locking the drill chuck body 1.

[0032] Furthermore, a locking member 4 is included. A mounting hole 22 is provided on the base 2 . The locking member 4 is matched and connected with the mounting hole 22 so that the locking member 4 locks the fixing plate 3 in the slot 21 .

[0033] Preferably, there are multiple mounting holes 22 , and the multiple mounting holes 22 are arranged at intervals along the circumference direction of the base 2 .

[0034] Specifically, one end of the mounting hole 22 is connected to the circumferential side wall of the base 2 , and the other end is connected to the slot 21 . One end of the locking member 4 passes through the side wall of the base 2 and the mounting hole 22 in sequence and then abuts against the fixing plate 3 .

[0035] Preferably, the locking member 4 is a bolt.

[0036] Furthermore, the number of the card slots 21 is four, the base 2 has two sets of side end walls that are arranged opposite to each other, and the four card slots 21 are respectively located at the middle position of each side end wall of the base 2 .

[0037] Specifically, the two oppositely disposed card slots 21 are communicated with each other.

[0038] In this embodiment, since the base 2 has two groups of side end walls that are arranged oppositely, that is, the base 2 has a front end wall, a left end wall, a rear end wall and a right end wall that are connected in sequence, a slot 21 is recessed at the middle position of each side end wall, and the slot 21 extends from the end away from the side end wall to the side end wall opposite to the current side end wall. More preferably, the slots 21 on the two opposite side end walls can be interconnected, thereby effectively improving production efficiency. Of course, the fixing plate 3 located on the two oppositely arranged slots 21 can also be integrally formed, thereby further improving the stability of the fixing plate 3 in positioning and clamping the drill chuck body 1.

[0039] In this embodiment, a plurality of mounting holes 22 are provided on the base 2, one end of each mounting hole 22 is connected to the side end wall, and the other end passes through the base 2 and is connected to the slot 21. Since the locking member 4 is made of a bolt, an internal thread is provided in the mounting hole 22, so that one end of the locking member 4 passes through the side wall of the base 2 and the mounting hole 22 in sequence and abuts against the fixing plate 3. At the same time, the other end of the locking member 4 is cooperatively installed on the entrance end of the mounting hole 22, so that each fixing plate 3 can be fixed in the slot 21 through the cooperative action of the plurality of locking members 4.

[0040] Preferably, a reinforcing plate 5 is provided at the lower end of the fixing plate 3 .

[0041] Furthermore, the width of the cross section of the reinforcing plate 5 is greater than the width of the cross section of the fixing plate 3 .

More preferably, the reinforcing plate 5 and the fixed plate 3 are integrally formed, so that the fixed plate 3 is firmly inserted into the slot 21 through the reinforcing plate 5, and the production cost of the product can also be reduced.

[0043] In particular, it also includes a turntable 6, a workbench and a motor, wherein the turntable 6 is rotatably arranged on the workbench, and the base 2 is arranged on the turntable 6, and the motor is arranged on the workbench and its output end is connected to the turntable 6 to drive the turntable 6 to rotate.

[0044] In this embodiment, the turntable 6 is rotatably arranged on the workbench, and the base 2 is fixedly installed on the turntable 6 so that the base 2 rotates synchronously with the turntable 6. The motor is arranged on the workbench and its output end is connected to the turntable 6 so that the motor drives the turntable 6 to rotate. At the same time, a cutting machine is correspondingly arranged on the workbench or at its external position. When the drill chuck body 1 is limited on the base 2 by multiple fixed plates 3 to position and clamp the drill chuck body 1, the cutting machine correspondingly cuts a cutting groove on the upper end of the drill chuck body 1, and at the same time drives the turntable 6 to rotate through the motor. In this way, the grooving work of the drill chuck body 1 can be completed, thereby avoiding errors caused by manual rotation and improving the processing accuracy.

[0045] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
