During the rotation of the rotating screw in the threaded sleeve, the clamping plate moves toward the touch pen until the touch pen is clamped and fixed. The provision of the clamping plate can clamp and fix touch pens of different sizes, thereby improving the practicality of the device. After the touch pen is clamped and fixed, the second rotating plate is rotated. The second rotating plate drives the second screw to rotate, thereby driving the touch pen to be adjusted in height, making it easier to hang the hook on the touch pen.

The output shaft of the rotating rod 207 passes through the outer wall of the fixed plate 208 and passes through the inner wall of the first housing 201, and is fixedly connected to one end of the outer wall of the first screw 202. A first rotating plate 209 is fixedly installed at one end of the outer wall of the rotating rod 207. The first rotating plate 209 can drive the rotating rod 207 to rotate, and the rotating rod 207 can drive the first screw 202 to rotate.

When the strength of the touch pen needs to be tested, first place the touch pen on the bottom end of the inner wall of the placement rack 304, and then rotate the third rotating plate 307. The third rotating plate 307 drives the rotating screw 306 to rotate. The rotating screw 306 drives the clamping plate 309 to move toward the touch pen during the rotation in the threaded sleeve 305 until the touch pen is clamped and fixed. The clamping plate 309 is provided, so that touch pens of different sizes can be clamped and fixed, which improves the practicality of the device. After the touch pen is clamped and fixed, rotate the second rotating plate 310. The second rotating plate 310 drives the second screw 302 to rotate, which can drive the touch pen to be adjusted in height, making it easier to hang the hook 206 on the touch pen. After the touch pen is fixed and clamped, the first rotating plate 209 is rotated. The first rotating plate 209 drives the rotating rod 207 and the first screw 202 to rotate. During the rotation process, the first screw 202 drives the push-pull force gauge 205 to move to a suitable position, and then the hook 206 on the push-pull force gauge 205 is inserted into the round hole of the touch pen. At this time, the first rotating plate 209 is rotated again. During the rotation process, the first rotating plate 209 drives the push-pull force gauge 205 away from the touch pen.
