[0027] Wherein, by brushing the two bonding plate 302 opposite side with the folding edge glue and close, after the folding edge glue solidification, using the electric telescopic rod 6 to the upper bonding plate 302 exert upward tension, if the upper bonding plate 302 and the lower bonding plate 302 still remain connected state after exceeding the set pressure threshold, it is test qualified.

[0028] With reference to Figure 4 , the limiting piece 304 includes slide plate 3041, bayonet 3042, pressing column 3043 and clasp 3044, the slide plate 3041 is slidably connected in the base 301, the slide plate 3041 bottom is connected with the clasp 3044, the moving plate 201 top is connected with the bayonet 3042 and the pressing column 3043, the bayonet 3042 is provided with two groups, symmetrically arranged on one side of the slide plate 3041 top.

[0029] With reference to Figure 3 , the T-shaped plate 303 horizontal segment is symmetrically provided with two groups of insertion holes 3031, and one end of the two groups of bayonets 3042 is respectively connected with the two groups of insertion holes 3031.

[0030] Wherein, the elastic supporting force of the clasp 3044 is generated on the slide plate 3041, so that the slide plate 3041 drives the bayonet 3042 to be inserted with the insertion hole 3031 on the T-shaped plate 303, so as to limit the T-shaped plate 303 in the T-shaped groove 3011, and the bonding plate 302 is installed on the base 301.

[0031] With reference to Figure 4 , the pressing column 3043 is located at the center of the slide plate 3041 top, and the outer side of the top end is provided with a let-out inclined surface.

[0032] Wherein, by exerting the pressing force on the pressing column 3043, the slide plate 3041 is extruded by the clasp 3044, and the bayonet 3042 is driven by the slide plate 3041 to be separated from the insertion hole 3031 during the extrusion process, so that the bonding plate 302 and the T-shaped plate 303 can be disassembled from the base 301; through the setting of the let-out inclined surface, when the bonding plate 302 is installed, it will drive the T-shaped plate 303 to exert an inclined force on the pressing column 3043 along the let-out inclined surface, so that the pressing column 3043 can drive the slide plate 3041 and the bayonet 3042 to descend under the action of force, thereby giving way to the T-shaped plate 303, improving the convenience of installation.

[0033] With reference to Figure 2The test assembly 2 comprises a moving plate 201, a connecting shaft 202, a pressing ring 203, a compression spring 204 and a pressure sensor 205.

[0035] Reference Figure 2 One side of the top plate 5 is provided with a control terminal 8. The electric telescopic rod 6 and the pressure sensor 205 are signal connected with the control terminal 8.

[0036] Working principle: After the opposite sides of the two bonding plates 302 are brushed with the folded edge glue, the upper bonding plate 302 is lowered to be close to the lower bonding plate 302 through the electric telescopic rod 6. One end of time is left for the folded edge glue to solidify. Then the test cylinder 7 is driven upward by the electric telescopic rod 6. The test cylinder 7 drives the pressing ring 203 to move upward. The pressing ring 203 drives the moving plate 201 to move upward through the compression spring 204. However, the bonding plate 302 drives the moving plate 201 to keep still through the bonding force. The moving plate 201 drives the compression spring 204 to press the pressing ring 203 in the reverse direction. The pressure sensor 205 senses the reverse pressure. If the upper bonding plate 302 and the lower bonding plate 302 still keep connected after exceeding the set pressure threshold, it means that the test is qualified. After the test is completed, the pressing column 3043 is pressed to drive the sliding plate 3041 to press the clamping spring 3044. In the pressing process, the moving plate 201 drives the clamping pin 3042 to be separated from the insertion hole 3031. The bonding plate 302 and the T-shaped plate 303 can be detached from the base 301, so as to prevent the bonding plate 302 from being repeatedly used and being affected by the cleaning.
