The bottom of the detection groove 21 is provided with a first positioning groove 23 and a second positioning groove 24. The first positioning groove 23 is provided for one end of the first positioning column 31 to be embedded, and the second positioning groove 24 is provided for one end of the second positioning column 33 to be embedded; a guide block 231 is fixedly connected to the groove wall of the first positioning groove 23, and a guide surface 311 is provided on the first positioning column 31, and the guide block 231 and the guide surface 311 are fitted. After the guide arm 8 is placed in the detection slot 21, the operator moves the first positioning column 31 so that one end of the first positioning column 31 moves into the first positioning slot 23. The guide block 231 can guide the movement of the first positioning column 31. The movement of the first positioning column 31 can drive the movement of the first positioning block 32 so that the first positioning block 32 is embedded in the through hole at one end of the guide arm 8. After the installation of the first positioning block 32 is completed, the operator moves the second positioning column 33 so that one end of the second positioning column 33 moves into the second positioning slot 24. The movement of the second positioning column 33 can drive the movement of the second positioning block 34 so that the second positioning block 34 is embedded in the through hole at the other end of the guide arm 8. The first positioning block 32 and the second positioning block 34 can limit the guide arm 8 so that the guide arm 8 is positioned in the detection slot 21, which is convenient for the detection of the guide arm 8.

[0033] like Figure 1 As shown, the workbench 1 and both ends of the detection mold 2 are fixedly connected with a quick clamp 6, and the quick clamp 6 is fixedly connected with a rotating frame 61.
