[0035] Specifically, the working principle of the split type large surrounding detection tool structure with positioning function is as follows: in use, the user adjusts the angle position of the clamping frame 1007 according to the type of the large surrounding.

At this time, the user adjusts the position and angle of the adjusting frame 1006 and the clamping frame 1007 according to the shape of the large surrounding. After the adjustment is completed, the user rotates the first nut 1012 and the second nut 1016 to fix the adjusting frame 1006 and the clamping frame 1007 in cooperation with the first limiting block 1011 and the second limiting block 1010. Then, the user places the side edge of the large surrounding on the upper end of the clamping frame 1007. The user rotates the screw rod 1015 to drive the slidingly connected clamping plate 1014 to descend and clamp and fix the side edge of the large surrounding. After the positioning and installation are completed, the user starts the first linear motor 1003, the second linear motor 1004 and the third linear motor 2001 through the touch panel 2005, so as to drive the laser displacement sensor 2004 to move around the large surrounding.
