[0025] The clamping mechanism 2 can be clamped on the back plate 1. When the clamping mechanism 2 is clamped on the back plate 1, the clamping mechanism 2 abuts against the adjusting mechanism 3, thereby making the clamping mechanism 2 and the adjusting mechanism 3 connected, and the two connected back plates 1 can be powered.

[0027] The guide groove 11 is an arc-shaped structure, the inner diameter of the give-way groove 12 is smaller than the inner diameter of the inner groove 15, and the inner groove 15 of the rotation groove 14 is the same as the groove depth of the give-way groove 12; when the engaging mechanism 2 enters the guide groove 11, passes through the through hole 13 and enters the inner groove 15 for engagement; when the engaging mechanism 2 rotates from the rotation groove 14 to the give-way groove 12, the engaging mechanism 2 can be removed from the back plate 1.
[0028] When the locking mechanism 2 passes through the through hole 13 from the guide groove 11 and enters the interior of the inner groove 15, the locking mechanism 2 stretches and is stuck on the groove wall of the inner groove 15, and the locking mechanism 2 will not detach from the inner groove 15. At the same time, the locking mechanism 2 will be pressed on the adjustment mechanism 3 when it is inserted into the inner groove 15, so that the locking mechanism 2 squeezes the adjustment mechanism 3 and can ensure that the locking mechanism 2 is always in contact with the adjustment mechanism 3, so that the stable connection of the circuit can be guaranteed during the detection process; when the two back panels 1 need to be disassembled, one of the back panels 1 is rotated so that the two back panels 1 rotate relative to each other, and the rotation of the back panel 1 drives the locking mechanism 2 to rotate. When the locking mechanism 2 rotates to the give way groove 12, the back panel 1 is pulled to move the locking mechanism 2 out of the back panel 1, and the two back panels 1 are separated.
[0029] The locking mechanism 2 includes a telescopic rod 28 arranged inside the back plate 1, and a card plate 21 is arranged on the end of the telescopic rod 28, and the card plate 21 slides at the end of the back plate 1; a first elastic member 29 is arranged on one side of the card plate 21, and the first elastic member 29 is sleeved on the telescopic rod 28, and the first elastic member 29 is used to push the card plate 21 to reset.

[0031] When it is necessary to insert the locking mechanism 2 in one back plate 1 into the other back plate 1 so that the locking plate 21 and the adjusting mechanism 3 are connected, align the locking plate 21 with the guide groove 11. Since the locking rod 22 is initially unfolded under the action of the torsion spring, when the locking rod 22 enters the guide groove 11, since the guide groove 11 is an arc-shaped structure, the locking rod 22 smoothly enters the inner groove 15. When the locking rod 22 enters the inner groove 15, the locking plate 21 just pushes the adjusting mechanism 3 to move to the maximum position. At this time, under the action of the first torsion spring 27, the locking rod 22 is pushed to the groove wall of the inner groove 15. Due to the action of the first stopper 24, the locking rod 22 When clamped, it will not flip over, and the clamping rod 22 will not disengage from the inner groove 15; when the clamping plate 21 needs to be removed, the back plate 1 is rotated, and the back plate 1 drives the clamping plate 21 to rotate, and the clamping rod 22 on the clamping plate 21 rotates from the inner groove 15 to the rotating groove 14, and then continues to rotate and allows the clamping rod 22 to enter the inside of the make way groove 12, and pulls the back plate 1 to make the clamping rod 22 disengage from the inside of the make way groove 12, thereby realizing the separation of the two back plates 1. Therefore, the clamping plate 21 and the adjustment mechanism 3 are separated at the same time, and there is no need to perform detection. The disassembly process is simple and easy to operate. When the clamping plate 21 is installed, the back plate 1 can be fixed, and the circuit connection function can be realized at the same time.

[0034] The movement of the adjusting rod 31 is arranged to facilitate the movement of the alligator clip. When the adjusting rod 31 moves, the alligator clip moves synchronously and is electrically connected. The movement of the slider 313 arranged at the bottom of the adjusting rod 31 can drive the limit block 310 to move synchronously. During the movement of the limit block 310, the flip block 311 can be squeezed, and the flip block 311 flips. When the limit block 310 is separated from the flip block 311, the flip block 311 rotates around the connecting pin 312 to the initial position; since a second torsion spring is arranged on the connecting pin 312, the second torsion spring is used to push the flip block 311 to reset; when the position is adjusted, it is necessary to adjust the unlocking component 33 to separate the baffle 314 from the limit block 310, so that the adjusting rod 31 can be reset; by moving the position of the adjusting rod 31, the adjusting rod 31 is moved to drive the alligator clip to move synchronously, so as to adapt to the testing of photovoltaic modules of different sizes.
[0035] The unlocking assembly 33 includes an adjustment plate 337 slidably arranged on the adjustment seat 36, a limiting rod 336 is arranged on the adjustment plate 337, a movable rod 334 is rotatably arranged on the adjustment plate 337, a limiting groove 335 is arranged on the movable rod 334, and the limiting rod 336 slides inside the limiting groove 335; a pull rod 332 is rotatably arranged on the end of the limiting rod 336, a second elastic member 333 is sleeved on the pull rod 332, the second elastic member 333 is used to push the pull rod 332 to reset, and a buckle 331 is arranged on the top of the pull rod 332; a moving rod is arranged at the end of the adjustment plate 337; a moving groove is opened on the side wall of the baffle 314, and the moving rod slides inside the moving groove.
[0036] When the locking cam 336 is in the process of being moved, the locking cam 336 pulls the adjusting plate 337 to move, and the adjusting plate 337 moves relative to the baffle 314, at this time, the baffle 314 rotates around the connecting pin 312, thereby separating the flip block 311 set on the baffle 314 from the limit block 310, and moving the adjusting rod 31 to the initial position; the unlocking assembly 33 provided can easily release the position locking effect of the adjusting rod 31, facilitate the resetting of the adjusting rod 31, and move the adjusting rod 31 to the position that needs to be adjusted. The adjustment process is simple, and when connecting the crocodile clip, it only needs to push the adjusting rod 31 to complete, and the operation is convenient.
[0037] When the present invention is in use, the card plate 21 connected to one back plate 1 is inserted into the other back plate 1, so that the card plate 21 is aligned with the guide groove 11. Since the card rod 22 is initially unfolded under the action of the torsion spring, when the card rod 22 enters the guide groove 11, since the guide groove 11 is an arc-shaped structure, the card rod 22 smoothly enters the inner groove 15. When the card rod 22 enters the inner groove 15, the card plate 21 just pushes the abutment plate 39 to move to the maximum position; at this time, under the action of the first torsion spring 27, the card rod 22 is pushed to the groove wall of the inner groove 15. Due to the action of the first stopper 24, the card rod 22 will not flip over when clamped, and thus the card rod 22 will not be separated from the inner groove 15; the adjustment rod 31 The movement of the slider 313 arranged at the bottom can drive the limit block 310 to move synchronously. During the movement of the limit block 310, the flip block 311 can be squeezed, and the flip block 311 flips. When the limit block 310 is separated from the flip block 311, the flip block 311 rotates around the connecting pin 312 to the initial position; since the connecting pin 312 is provided with a second torsion spring, the second torsion spring is used to push the flip block 311 to reset; when the position is adjusted, the baffle 314 needs to be separated from the limit block 310 by adjusting the unlocking component 33, so that the adjustment rod 31 can be reset; by moving the position of the adjustment rod 31, the adjustment rod 31 is moved to drive the crocodile clip to move synchronously, so as to adapt to the testing of photovoltaic modules of different sizes. During the test, multiple pairs of wire crocodile clips can be added as needed to conduct a series-parallel power-on scheme for the photovoltaic modules. After the test is completed, multiple back panels 1 need to be removed. When removing the card plate 21, rotate the back panel 1, and the back panel 1 drives the card plate 21 to rotate. The card rod 22 on the card plate 21 rotates from the inner groove 15 to the rotation groove 14, and then continues to rotate and allows the card rod 22 to enter the inside of the make way groove 12, pull the back panel 1, so that the card rod 22 is disengaged from the inside of the make way groove 12, and then the two back panels 1 are separated. Therefore, the card plate 21 and the adjustment mechanism 3 are separated at the same time, and there is no need to perform detection. The disassembly process is simple and easy to operate. When the card plate 21 is installed, the back panel 1 can be fixed and the circuit connection function can be achieved at the same time.
