The second rotation points are located between the first rotation points and the driving end of the driving part 31, so that the driving part 31 forms a lever structure. When the second probe row 8 needs to move towards the first probe row 2, the driving end is pressed, the first connecting rods 33 drive the first connecting members 32 to move downwards, and the downward force of the first connecting members 32 drives the two first sliding blocks 12 to slide downwards along the first sliding track 11, so that the second probe row 8 moves towards the first probe row 2, and the first probe and the second probe respectively contact the grid lines to test the solar cell.

[0037] Optionally, the driving end of the driving part 31 is the end operated by the user, and is also the end connected with the first connecting arm 311 and the second connecting arm, that is, the user can press the second connecting arm to drive the whole driving part 31 to move.

[0044] As shown in Figure 2As shown, as an embodiment, the driving part 31 comprises two first connecting arms 311 and a second connecting arm, two ends of the second connecting arm are connected with the two first connecting arms 311 respectively, that is, the driving part 31 is in a non-closed frame structure, which is convenient for the user to operate; the two first connecting arms 311 are respectively located at two ends of the second probe row 8, the first connecting arm 311 is provided with a first rotation point and a second rotation point, and at least one first connecting arm 311 is further provided with a positioning pin 4; the support 1 on the same side of the positioning pin 4 is further provided with a fixed block 5, and the positioning pin 4 can be inserted into different positions of the fixed block 5. Since the embodiment of the present application is driven to move up and down by manual operation, the positioning pin 4 is inserted into the fixed block 5 when the second probe row 8 moves to the set position, so as to avoid the movement of the second probe row 8.

[0045] Optionally, the fixed block 5 is provided with two different positions for the positioning pin 4 to be inserted, that is, the highest position and the lowest position that the second probe row 8 can move to.

[0046] As shown in Figure 2 Optionally, the fixed block 5 is in an arc structure and is fixed on one side of the support 1, the fixed block 5 is respectively provided with an insertion hole 51 at two extreme positions, the positioning pin 4 can be respectively inserted into different insertion holes 51, and the insertion holes 51 at the two extreme positions are respectively the highest position that the second probe row 8 can be lifted to and the lowest position that the second probe row 8 can move to the first probe row 2, that is, when the second probe row 8 is lifted again, the positioning pin 4 can be inserted into the insertion hole 51 at the highest position, which is convenient for the solar cell to be put in; when the solar cell needs to be tested, the positioning pin 4 is pulled out of the insertion hole 51, the second connecting arm is pressed to move the second probe row 8 downward, the probe is aligned with and contacts the grid line of the solar cell, and then the positioning pin 4 is inserted into the insertion hole 51 at the lowest position, so as to fix the relative position of the second probe row 8 and prevent the second probe row 8 from continuing to drop and scratching the solar cell.

[0047] Optionally, the fixed block 5 is provided with a plurality of arc grooves, a plurality of bolts pass through the arc grooves and are connected with the support 1, since the first probe row 2 can also move relative to the second probe row 8, when the first probe row 2 moves, the lowest position that the second probe row 8 can drop to will also change, therefore, the position of the fixed block 5 also needs to be adjusted, and the purpose of setting the arc grooves is to facilitate the adjustment of the position of the fixed block 5, that is, the bolts do not need to be completely disassembled, but are slightly loosened, and then the fixed block 5 is moved, and the moving range of the fixed block 5 is the length of the arc groove.

[0048] As shown in Figure 1 and 2As shown, as an embodiment, the first probe row 2 can be moved relative to the support 1, so that the height of the first probe row 2 can be adjusted, facilitating the carrying of the solar cell.

On the one hand, by supporting one end of the first connecting arm 311 through the second support rod, the structure is smooth when pressing or lifting the driving part 31; on the other hand, since the height of the first probe row 2 can be adjusted, when the height of the first probe row 2 is adjusted, the lowest position to which the second probe row 8 can be lowered also changes, so the position of the fixed block 5 on the support 1 also needs to be adjusted. When the height position of the first probe row 2 changes, the second connecting piece 34 drives the second connecting rod 35 to move, and the second connecting rod 35 drives the first connecting arm 311 to move, and the first connecting arm 311 is rotatably connected with the connecting block 6 and the first connecting rod 33 respectively. Therefore, when the height of the first probe row 2 is adjusted, the second connecting rod 35 drives the first connecting arm 311 to move during the adjustment process, and then the driving part 31 is pressed to determine the lowest position to which the second probe row 8 can be lowered. At this time, the position to which the positioning pin 4 on the driving part 31 is aligned is also the position to which the fixed block 5 needs to be moved, facilitating accurate determination of the moving position of the fixed block 5.
