Example 1:
as shown in fig. 1, the present embodiment provides a detection fixture, which includes a first substrate 1, a fixing component 3, and an adjusting component; specifically, the first substrate 1 is used for carrying a display screen to be detected; the fixing component 3 is arranged on the first substrate 1 and is used for fixing a display screen to be detected; the adjusting component is used for adjusting the form of the fixing component 3 so that the fixing component 3 can fix display screens with different sizes; in the process of adjusting the shape of the fixing component 3 by the adjusting component, the shape change of the fixing component 3 refers to the width change of the opening part of the fixing component 3 for clamping the display screen so as to fix the display screens with different sizes, and the shape change is not limited to the shape change caused by the material of the fixing component 3, and can also be caused by the movement of the components in the fixing component 3.
Since the adjusting component in the detecting jig of the embodiment can adjust the form of the fixing component 3 according to the specific size of the display screen to be detected, the fixing component 3 can fix the display screens with different sizes; therefore, when detecting the display screens with different sizes, the detection jig for detecting the auxiliary display screen is not replaced any more, that is, the display screens with different sizes can be fixed by the same fixing component 3 (in other words, one detection jig can be used for detecting the display screens with different sizes). Therefore, the detection jig in the embodiment not only solves the problem that the display screens with different sizes cannot share the same detection jig, but also greatly reduces the working difficulty and the production cost of operators.
Example 2:
as shown in fig. 1 and 2, the present embodiment provides a detection fixture, which includes a first substrate 1, a fixing component 3, and an elastic component; the fixing assembly 3 comprises a first stop lever 31 and a second stop lever 32, the first stop lever 31 and the second stop lever 32 comprise a first end part and a second end part, and a first end part 311 of the first stop lever is connected with a first end part 321 of the second stop lever; the adjustment assembly secures different sized display screens by adjusting the spacing between the second end 312 of the first bar and the second end 322 of the second bar.
It should be noted that the adjusting assembly may adjust the position of one of the first bar 31 and the second bar 32, or adjust the positions of the first bar 31 and the second bar 32 at the same time, so as to change the distance between the second end 312 of the first bar and the second end 322 of the second bar; wherein, the larger the size of the display screen, the larger the distance between the second end 312 of the first bar and the second end 322 of the second bar; the smaller the size of the display screen, the smaller the spacing between the second end 312 of the first bar and the second end 322 of the second bar.

The adjusting component is connected with the sliding stop lever 33, and can control the sliding stop lever 33 to move back and forth along the sliding track, so that the size of the opening of the fixed component 3 is adjusted; the sliding track of the sliding bar 33 refers to a vertical extension line of the connection point between the first end 311 of the first bar and the first end 321 of the second bar on the sliding bar 33. Specifically, when the adjusting assembly controls the sliding bar 33 to move toward the first ends 311 (321) of the first bar and the second bar, the distance between the second ends 312 and 322 of the first bar and the second bar increases, for fixing a large-sized display screen; when the adjusting assembly controls the sliding bar 33 to move toward the opening of the fixing assembly 3, the distance between the second end 312 of the first bar and the second end 322 of the second bar becomes smaller for fixing the small-sized display screen.
Preferably, the fixing assembly 3 further includes: a spring 34; the spring 34 is located at one side of the sliding bar 33 near the opening of the fixed assembly 3, and one end of the spring 34 is connected to the first bar 31, and the other end is connected to the second bar 32. When the fixing component 3 fixes the display screen to be detected, the first stop lever and the second stop lever 32 in the fixing component 3 are simultaneously subjected to the reaction force exerted by the clamped display screen, and at this time, since the spring 34 is arranged in the fixing component 3 and has elasticity, the spring 34 can pull the first stop lever 31 towards the second stop lever 32, and pull the second stop lever 32 towards the first stop lever 31, so that the first stop lever 31 and the second stop lever 32 clamp the display screen.
Preferably, the fixing assembly 3 further includes: a fixing portion 35; the second end 312 of first pin is connected to the one end of this fixed part 35, and the second end 322 of second pin is connected to the other end for when fixed subassembly 3 is fixed the display screen of waiting to detect, the display screen of waiting to detect is fully laminated to fixed part 35, has not only avoided first pin 31, second pin 32 to cause the emergence of the condition of wearing and tearing to the periphery of display screen, can also further fix the display screen.
