The first electric telescopic rod 407 is activated via the digital display control panel 8, pushing the clamping block 404 to slide within the adjustment slot 403. This, in conjunction with the guide rod 408, securely clamps the smartwatch in the two edging grooves between the two clamping blocks 404. The upper pressing edge 406 further secures the smartwatch.

[0058] Based on the testing requirements, the fourth motor 411 is activated via the digital control panel 8 to drive the U-shaped bracket 401 to deflect to the appropriate angle between the two second inner support frame rods 202. The cylinder 412 is then activated to insert the clamping cone 413 into the positioning cone hole 414 for positioning, thereby enabling pressure testing of the touch screen at different tilt angles. Additionally, the third motor 410 can be activated to rotate the rotating platform 402 to adjust the orientation of the smartwatch touch screen. This, in conjunction with the first electric telescopic rod 407 driving the two clamping blocks 404, allows for pressure testing of any point on the touch screen. Alternatively, the second electric telescopic rod 409 can be activated via the digital control panel 8 to drive the lifting column 405 up and down within the lifting channel within the rotating platform 402, thereby enabling support testing or suspension testing of the touch screen.

[0059] If the touch pressure head 306 needs to be replaced, the fifth motor 504 is started through the digital display control panel 8, the driving wheel turntable 502 rotates, and the second slot 503 where the required touch pressure head 306 is located is turned to the appropriate position. The linear drive component 6 drives the rotation detection touch pressure structure 3 to approach the touch pressure head rotation replacement structure 5, so that the end of the touch pressure head 306 away from the second slot 503 is inserted into the first slot 302, and then the third electric telescopic rod 507 is started to drive the anti-slip pressure head 506 to slide in the telescopic channel 505, and the touch pressure head 306 is released. The magnetic head 303 realizes the magnetic fixation of the touch pressure head 306 in the first slot 302 and installs it in the first slot 302 of the rotation detection touch pressure structure 3. After the installation is completed, the third electric telescopic rod 507 is started again to fix the anti-slip pressure head 506 to the touch pressure head 306. The second motor 305 is started through the digital display control panel 8 to drive the detection disk 301 to rotate, and the installed touch pressure head 306 is turned to the working position. During the above operation process, the touch pressure head 306 on the detection disk 301 can also be replaced on the touch pressure head rotation replacement structure 5, thereby completing various operation modes such as installation, replacement, and removal of the touch pressure head 306 on the rotating detection touch pressure structure 3.

[0060] The fourth electric telescopic rod 601 is activated through the digital display control panel 8, driving the first slider 602 to slide in the second guide slot 204. The detection disk 301 and the touch pressure head 306 are driven to approach the smart watch touch screen through the magnetic connection of the connecting rod 603 and the first electromagnetic suction head 605 and the second electromagnetic suction head 606. The pressure sensor 604 detects the pressure in real time and feeds it back to the digital display control panel 8. When the preset pressure value is reached, the fourth electric telescopic rod 601 stops moving, maintains it for a certain period of time, and then drives the touch pressure head 306 to separate from the touch screen, thereby completing the pressure resistance performance test under static pressure.

[0061] When ejection mechanism 7 is activated, distance sensor 703 detects the distance between the ejection sleeve 704 and the end face and provides feedback to digital control panel 8. Spring 702 accumulates force, pushing pressure pad 705 against second slider 607. When first electromagnetic suction head 605 and second electromagnetic suction head 606 separate, test disc 301 and touch head 306 are ejected, completing the impact and pressure resistance test of the touch screen and testing its compressive performance. During this process, the ejection force can be adjusted via digital control panel 8 based on the data fed back by distance sensor 703. Furthermore, the outer support frame deflection drive assembly 1 can adjust the inner support frame structure 2 to a horizontal position, and the ejection direction of touch head 306 is horizontal, thereby preventing factors such as gravity from significantly affecting the ejection force.

[0062] After the test is completed, the components are reset through the digital display control panel 8, and the tested smart watch is taken out. If the next test is required, the above steps can be repeated.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
