[0025] As shown in Figures 1 to 6 The detection mechanism mainly comprises a baffle 2, an elastic driving member 3, a linear guide rail 4, a linkage assembly, a measuring tool 8 and a mounting bottom plate 9. The linear guide rail 4 is fixedly installed on the operation table 1, and the linear guide rail 4 comprises slide rails 4a, slide tables 4b, connecting rods 4c and guide rail mounting seats 4d. Two guide rail mounting seats 4d are oppositely installed on the operation table 1, two parallel slide rails 4a are installed between the two guide rail mounting seats 4d, and the two slide rails 4a extend along the length direction of the operation table 1. Two slide tables 4b are slidably installed on each slide rail 4a respectively.

Specifically, the guide rail mounting seat 4d is provided with a bottom plate mounting hole 4d1, and the two ends of the mounting bottom plate 9 are embedded in the corresponding bottom plate mounting hole 4d1 respectively. The mounting bottom plate 9 is used for placing a detection object, and the mounting method is simple and reliable and has strong bearing capacity. The mounting bottom plate 9 has a hollow structure, and the aluminum scrap on the pipe can fall from the hollow structure, so that the aluminum scrap is prevented from accumulating on the mounting bottom plate 9. Specifically, the mounting bottom plate 9 is provided with circular holes 9a arranged in a rectangular array, which is more conducive to the falling of the aluminum scrap.

[0027] The two baffles 2 are vertically arranged above the mounting bottom plate 9 in parallel with each other. One of the two baffles 2 is installed on the top of the two slide tables 4b close to one of the guide rail mounting seats 4d and is connected to the bottom through a connecting rod 4c. The other baffle 2 is installed on the top of the two slide tables 4b close to the other guide rail mounting seat 4d and is connected to the bottom through another connecting rod 4c.
