The limit plate 34 is loosened, and the spring 33 drives the limit plate 34 to contact the connecting wire 4, so that the angle of the connecting wire 4 can be limited by the limit plate 34, avoiding the use of When the detection head 5 is used, the connection line 4 and the thickness gauge body 1 become loose, affecting the use effect. When the spring 33 drives the limit plate 34 to move, the telescopic rod 36 installed in the spring 33 can limit the movement of the spring 33. The telescopic rod 36 can prevent the spring 33 from deforming during use. After the limit plate 34 is used to contact the connecting line 4, the limit groove 35 opened on the limit plate 34 can increase the friction between the limit plate 34 and the connecting line 4, thereby preventing the connecting line 4 from sliding in the limit plate 34 and improving the stability of the connecting line 4 in the limit plate 34.
