[0025] A fixing frame 3 is movably installed at the lower end of one side of the second fixing plate 12, a straight rod 31 is fixedly installed on the inner side of the upper end of the fixing frame 3, a straight plate 33 is fixedly installed on the other end of the straight rod 31, and a pressure sensor 4 is detachably installed on one side of the straight plate 33, a speaker 5 is fixedly installed on the lower end of the outer side of the first fixing plate 11, a spring 32 is sleeved on the outer wall of the straight rod 31, and the other end of the spring 32 is fixedly connected to the second fixing plate 12, so that the spring 32 can be set to facilitate the spring 32 to drive the fixing frame 3 to reset by virtue of the resilience of the spring 32, a rubber positioning piece 21 is bonded to the inner cavity of the positioning cylinder 2, and a positioning slot is opened in the middle of the rubber positioning piece 21, so as to facilitate the limitation of the tool by the rubber positioning piece 21, and one side of the positioning cylinder 2 is rotatably connected to the inner side of the first fixing plate 11 through a bearing, so as to ensure the stability of the positioning cylinder 2, thereby facilitating the rotation of the positioning cylinder 2.

[0026] A convex lens 23 is detachably mounted in the middle of the detection frame 22 , and the lower end of the convex lens 23 passes through the upper end of the detection frame 22 . The setting of the convex lens 23 facilitates observation of the tip of the tool through the convex lens 23 .

[0027] A traction rope 34 is wound around the outer wall of the winding drum 24, and the other end of the traction rope 34 passes around the guide wheel and is fixedly connected to the lower end of the fixed frame 3. Through the setting of the traction rope 34, it is convenient for the traction rope 34 to drive the fixed frame 3 to move, so that the pressure sensor 4 on the fixed frame 3 contacts the tip of the tool.

[0028] During the inspection, first insert the tool to be inspected into the rubber positioning piece 21 of the positioning cylinder 2, so as to limit the tool and place the tip of the tool in the inspection frame 22, and then slowly rotate the positioning cylinder 2, which drives the tool to follow the rotation, so that the staff can observe the slight damage of the tip of the tool through the convex lens 23, and further improve the inspection efficiency of the tool. At the same time, during the rotation of the positioning cylinder 2, the winding drum 24 on the positioning cylinder 2 reels the traction rope 34, and the traction rope 34 pulls the fixed frame 3 to move to the left, so that the straight plate 33 on the fixed frame 3 follows the movement.
