[0045] In the embodiments of the present disclosure, reference Figures 1 to 10 As shown,

[0046] The first mounting plate 201 mounts a set of test mechanisms 3 in the vertical position. The test mechanism 3 is jointly composed of a driving member 301, a guiding disk 302, a rocker arm 303, a driving plate 304, a sliding plate 305, a rack 306, a driving shaft 307, a gear 308, a swing frame 309, and a friction sleeve 310. The third mounting plate 203 is provided with a set of uniformly distributed rotating holes. The driving shaft 307 passes through the interior of the rotating holes. The third mounting plate 203 cooperates with the rotating holes to stabilize the rotating position of the driving shaft 307, enabling the driving shaft 307 to rotate stably. A gear 308 is mounted on the outer side of the driving shaft 307, and a rack 306 is mounted on the outer side of the sliding plate 305. The sliding plate 305 drives the rack 306 to move synchronously. The rack 306 meshes with the gear 308. By controlling the driving member 301, the sliding plate 305 and the rack 306 are controlled to move. At this time, the rack 306 drives the gear 308 to rotate forward and backward, and at this time, the driving shaft 307 is stressed to rotate forward and backward. The driving member 301 includes a commutator and a motor. A guiding disk 302 is mounted above the driving rod of the commutator. The motor and the commutator cooperate to drive the guiding disk 302 to rotate. A sliding groove with a U-shaped structure is formed above the guiding disk 302. One end of the rocker arm 303 is provided with a sliding block at the bottom position. The rocker arm 303 and the end of the sliding block are rotatably connected. The sliding block is mounted inside the sliding groove of the guiding disk 302. Therefore, when the guiding disk 302 rotates, the sliding block and the guiding disk 302 are equivalent to a cam to drive the rocker arm 303 to swing. A rotating block with a cylindrical structure is provided above the driving plate 304. The rotating block passes through the other end of the rocker arm 303, and the rotating block and the rocker arm 303 are rotatably connected. According to the principle of the crank-slider, the rocker arm 303 can control the driving plate 304 to reciprocate when rotating. A swing frame 309 is mounted at the end of the driving shaft 307, and two friction sleeves 310 are mounted at the end of the swing frame 309. With the cooperation of the swing frame 309, the friction sleeves 310 deviate from the center position of the driving shaft 307. In turn, the driving shaft 307 drives the two friction sleeves 310 to swing reciprocally;

[0047] In the embodiment of the present disclosure, with reference to Figures 1 to 10 as shown

[0048] The first mounting plate 201 mounts two positioning plates 4 at the upper position. The first mounting plate 201 opens two positioning grooves with a rectangular structure at the upper position. The bottom of the positioning plate 4 is mounted inside the positioning groove. The positioning groove positions and stabilizes the mounting position of the positioning plate 4. The positioning plate 4 opens a set of bolt mounting holes, and the bolt mounting holes are used to mount fixing bolts. The positioning plate 4 mounts an orbit 5 at the upper position. The driving plate 304 mounts two sliding plates 305 at the bottom position. The sliding plate 305 opens a sliding groove at the bottom position, and the sliding groove corresponds to the orbit 5. The orbit 5 positions the sliding plate 305 vertically and circumferentially. The sliding plate 305 moves horizontally stably along the orbit 5. The sliding plate 305 and the orbit 5 cooperate with each other to achieve the effect of positioning the driving plate 304 vertically and circumferentially, so that the driving plate 304 moves horizontally stably. The positioning plate 4 opens a positioning groove with a U-shaped structure at the upper position. The bottom of the orbit 5 is mounted inside the positioning groove. The positioning groove positions the mounting position of the orbit 5, which is convenient for the orbit 5 to be stably mounted above the positioning plate 4 in cooperation with bolts;

[0049] In the embodiment of the present disclosure, refer to Figures 1 to 10 as shown in

[0050] The second mounting plate 202 mounts ten groups of evenly distributed first stabilizing plates 6 at the upper position. The first stabilizing plate 6 mounts a paste plate 7 at the inner position. The paste plate 7 mounts a hinged finger ring 8 at the outer position. The second mounting plate 202 opens a set of positioning grooves with a rectangular structure at the upper position. Two symmetrically distributed first stabilizing plates 6 are mounted at the position of the positioning groove. The first stabilizing plate 6 opens a set of bolt mounting grooves at the bottom position. The bolt mounting grooves facilitate the first stabilizing plate 6 to be mounted above the second mounting plate 202 in cooperation with bolts. The paste plate 7 is mounted between the two first stabilizing plates 6. The first stabilizing plate 6 stabilizes the mounting position of the paste plate 7. The finger ring 8 passes through the inner positions of the two swing frames 309. Therefore, when the swing frame 309 swings, it can control the finger ring 8 to swing. At this time, a fatigue automatic test is performed on the rotating shafts of the paste plate 7 and the finger ring 8. The paste plate 7 is provided with two rotating shafts on the outer side surface. The finger ring 8 is provided with an opening groove, and a set of rotating grooves are opened at the position of the opening groove. The rotating shafts are mounted inside the rotating grooves. At this time, the paste plate 7 and the finger ring 8 achieve the effect of hinging. The paste plate 7 and the finger ring 8 cooperate with each other to form a bracket for a mobile phone case.
