When the staff slides the installation limit block 3 into the fixed seat 1, the side where the installation limit block 3 contacts the connecting block 31 is provided with a slope, so that the installation limit block 3 will drive the connecting block 31 to move vertically, so that the connecting block 31 can drive the clamping plate 32 to move vertically, and the clamping plate 32 is in direct contact with the slotting knife 11, so that the clamping plate 32 will press the slotting knife 11 is pressed and fixed to prevent the slotting knife 11 from having unnecessary displacement during the slotting process of the workpiece, so as to ensure that the slotting knife 11 can complete the slotting work of the workpiece, and a locking block 2 is installed on the top of the fixed seat 1 for sliding, and the locking block 2 will limit the position of the linkage block 31, so that when the installation limit block 3 slides into the fixed seat 1 and the slotting knife 11 is pressed and fixed by the linkage block 31 and the clamping plate 32, the staff can fix the position of the linkage block 31 by sliding the installation locking block 2 into the fixed seat 1, so that the clamping plate 32 can continue to press and fix the slotting knife 11, and because the clamping plate 32 is installed The limit block 3 and the linkage block 31 are limited and cannot move vertically, and the installation limit block 3 is limited by the installation locking block 2, so that the slotting knife 11 will not be offset during the slotting process of the workpiece. The position of the push-out block 33 sliding inside the fixed seat 1 corresponds to the installation limit block 3, so that when the staff needs to replace the slotting knife 11, the staff can first slide the installation locking block 2 to make the installation locking block 2 cancel the limit on the installation limit block 3, and then the staff can slide the push-out block 33 to drive the installation limit block 3 to slide out from the inside of the fixed seat 1, thereby canceling the pressing and fixing work of the slotting knife 11, so that the staff can take out the slotting knife 11 for replacement.
[0018] A giving way groove 12 and an alignment groove 13 are provided inside the fixed seat 1, and the giving way groove 12 and the alignment groove 13 are connected. The installation locking block 2 and the installation limit block 3 are slidably connected to the fixed seat 1 through the giving way groove 12 and the alignment groove 13 respectively; the giving way groove 12 provided inside the fixed seat 1 is used to give way for the sliding of the installation locking block 2, so that the staff can slide the installation locking block 2 to the inside of the fixed seat 1 to complete the limiting work of the installation limit block 3, and then the installation limit block 3 can limit the linkage block 31 and the clamping plate 32, thereby completing the clamping and fixing of the slotting knife 11, and the alignment groove 13 provided inside the fixed seat 1 is used to give way for the sliding insertion of the installation limit block 3, so that the staff can slide the installation limit block 3 to the inside of the fixed seat 1 to drive the linkage block 31 and the clamping plate 32 to move vertically, thereby completing the clamping and fixing of the slotting knife 11.
[0019] An installation opening 14 is provided inside the fixing seat 1, and the slotting knife 11 slides inside the installation opening 14; the installation opening 14 provided inside the fixing seat 1 is used to make way for the insertion of the slotting knife 11, so that the staff can insert the slotting knife 11 into the fixing seat 1, and then through the cooperation of various components, the slotting knife 11 is pressed and fixed.
[0020] An extension block 34 is fixedly connected to one side of the installation limit block 3, and the position of the extension block 34 corresponds to the push-out block 33; the extension block 34 fixed on one side of the installation limit block 3 is used to drive the installation limit block 3 to move, so that the staff can drive the extension block 34 to move by sliding the push-out block 33, so that the installation limit block 3 can slide out from the inside of the fixed seat 1, thereby canceling the pressing and fixing work of the slotting knife 11, so that the staff can replace the slotting knife 11.
[0021] The auxiliary block 35 is fixedly connected to one side of the ejection block 33, and the auxiliary block 35 slides inside the fixed seat 1. The fixed seat 1 is rotatably connected to an adjusting rod 41, and the position of the adjusting rod 41 corresponds to the positioning block 4; the auxiliary block 35 fixed on one side of the ejection block 33 is used to assist the sliding of the ejection block 33, so that when the staff slides the ejection block 33, the ejection block 33 will not be offset, ensuring that the ejection block 33 can drive the installation limit block 3 to move, and the adjusting rod 41 rotating inside the fixed seat 1 is used to fix the position of the positioning block 4, so that when the staff slides the fixed seat 1 to a suitable position, the positioning block 4 can be pushed to contact the slotting knife 11 by rotating the adjusting rod 41, thereby positioning and fixing the position of the slotting knife 11, and because the slotting knife 11 is mainly fixed by the clamping plate 32, when the slotting knife 11 slots the workpiece, the force fed back by the slotting knife 11 to the positioning block 4 is limited, so that the surface thread of the adjusting rod 41 will not be greatly worn.
[0022] The working principle and use process of the utility model are as follows: when the staff needs to groove the workpiece, the staff can first insert the groove cutter 11 into the fixed seat 1 and expose the groove cutter 11 to the outside world to a suitable length. Then the staff can move the positioning block 4 until it contacts the groove cutter 11 to complete the positioning of the groove cutter 11. Then the staff can insert the installation limit block 3 into the fixed seat 1. When the installation limit block 3 slides into the fixed seat 1, it will contact the linkage block 31. Since the contact surfaces of the installation limit block 3 and the linkage block 31 are both provided with a slope, the installation limit block 3 will drive the linkage block 31 to move vertically, and the linkage block 31 will drive the clamping plate 32 to move vertically downward, so that the clamping plate 32 completely contacts the groove cutter 11 and is fixed to the workpiece. The slotting knife 11 is pressed and fixed, and then the staff can slide the installation locking block 2 to the inside of the fixed seat 1, so that the installation locking block 2 limits the installation limit block 3, ensuring that the clamping plate 32 can continue to press the slotting knife 11. When the slotting knife 11 is worn and needs to be replaced, the staff can slide the installation locking block 2 out of the fixed seat 1 to cancel the limit on the installation limit block 3. Then the staff can slide the push-out block 33 so that the push-out block 33 drives the installation limit block 3 to slide out of the fixed seat 1 through the extension block 34. At this time, the clamping plate 32 will move to its original position driven by the spring, thereby canceling the clamping and fixing of the slotting knife 11. Then the staff can slide the slotting knife 11 out of the fixed seat 1 to complete the replacement of the slotting knife 11.
