[0007] The fixed jaw is provided with a T-shaped opening groove on the side facing the quick-change jaw, and a locking rod is inserted into the T-shaped opening groove.

[0008] Further, the locking rod is provided with a spring on the side away from the T-shaped opening groove.

[0009] Further, the quick-change jaw is provided with an end face positioning block on the side close to the fixed jaw, and a cylindrical head screw is connected to the end face positioning block for fixation.

[0010] Further, the top of the locking rod is provided with an inclined surface groove matched with the driving rod, and the driving rod is provided with an inclined surface matched with the inclined surface groove on one side.

[0011] Furthermore, the fixed jaws are provided with slots for engaging the locking rod and the drive rod, and the top of the fixed jaws is provided with screw holes for engaging the clamping screws.

[0012] The advantages of this utility model's composite quick-change jaw structure compared to the prior art are: 1. It provides a composite quick-change flat jaw structure, solving the problem of inconvenient jaw replacement for current flat jaw pliers;

[0013] 2. It enables efficient and rapid jaw replacement, reducing jaw replacement time and improving production efficiency. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figures 1-4 A composite quick-change jaw structure includes a fixed jaw 1 and a quick-change jaw 5. The quick-change jaw 5 is connected to an end face positioning block 7 on the side near the fixed jaw 1. A cylindrical head screw 6 for fixing is connected to the end face positioning block 7. The quick-change jaw 5 is provided with a T-shaped opening groove 10 on the side facing the fixed jaw 1. A locking rod 4 is inserted into the T-shaped opening groove 10. The head of the locking rod 4 is T-shaped to match the T-shaped opening groove 10.

[0021] The locking rod 4 is provided with a spring 9 away from the T-shaped opening slot 10, the top of the locking rod 4 is connected to the driving rod 3, the fixed jaw 1 is connected with the compression screw 2 matched with the driving rod 3, the compression screw 2 is provided with a plurality of settings, the driving rod 3 is connected with the circlip 8 matched with the compression screw 2, the top of the locking rod 4 is provided with the inclined surface slot 11 matched with the driving rod 3, one side of the driving rod 3 is provided with the inclined surface 12 matched with the inclined surface slot 11, the fixed jaw 1 is provided with the empty slot 13 matched with the locking rod 4 and the driving rod 3, and the top of the fixed jaw 1 is provided with the screw hole 14 matched with the compression screw 2.

[0022] Firstly, the fixed jaw 1 is fixed on the flat-nose pliers through the screw 2, then the quick-change jaw 5 is inserted into the locking rod 4 through the T-shaped slot, the end surface is close to the end surface positioning block 7, three compression screws 2 are rotated respectively, the driving rod 3 moves downward, the inclined surface 12 on the driving rod 3 is matched with the inclined surface slot 11 on the locking rod 4, under the action of the driving rod 3, the locking rod 4 moves backward, the quick-change jaw 5 is compressed on the fixed jaw 1, the clamping and positioning are completed, when the quick-change jaw is disassembled, the three compression screws 2 are rotated reversely, under the action of the circlip 8, the driving rod 3 moves upward, under the condition that the driving rod 3 is not limited, the locking rod 4 moves forward under the action of the spring 9, the quick-change jaw 5 is loosened, the quick-change jaw 5 is pulled out from the fixed jaw 1, and the disassembly is completed.
