The headrest rod is usually made of metal material with a certain strength and durability to ensure that the passenger's head can be protected in the event of a vehicle collision.

[0003] In the application process of automobile headrest rods, it is necessary to perform compression testing on the automobile headrest rods to ensure strength and avoid insufficient strength affecting normal use, and then use compression testing devices.

After the fixation is completed, the detection plate and the compression test block are driven down by the telescopic cylinder, so that the top end face of the shaft retaining ring can be accurately and in place to detect the top end face of the shaft retaining ring, thereby ensuring product quality.

[0005] Although this patent can accurately and precisely detect the top end face of the shaft retaining ring, thereby ensuring product quality, the existing compression testing device still has certain shortcomings. For example, during the compression testing process, it is impossible to perform compression testing with multi-directional angle changes, resulting in relatively single data obtained, and thus it is impossible to fully understand the strength of the pillow rod, thereby reducing the accuracy of the compression test data.
