[0033] The adjustment component 6 includes a connection frame 601, and the connection frame 601 is installed on one side of the inner cavity of the installation frame 4. A spring 605 is installed on the bottom surface of the inner cavity of the connection frame 601, and a lifting plate 603 is installed on the top surface of the spring 605. A threaded rod 602 is rotatably installed on the side of the lifting plate 603 away from the spring 605, and the threaded rod 602 is threadedly installed on the top surface of the connection frame 601;

[0034] The top surface of the installation frame 4 is provided with a transmission plug 2 14, a connection line 13 is connected between the transmission plug 2 14 and the plug board 10, and the side wall of the detection box 1 is provided with a transmission plug 1 8 and a power interface 9;

[0035] The detection box 1 is provided with a display panel 2, which is used to display the data of the detection relay of the detection box 1, and the detection box 1 is provided with an operation panel 3, which is used to adjust the detection box 1;

[0036] Furthermore, a transmission line 5 is connected between the transmission plug 2 14 and the transmission plug 1 8, and the transmission line 5 is used to connect the detection box 1 with the plug board 10. When the device is used, the detection box 1 is first powered on through the power interface 9, and then the detection box 1 and the transmission plug 2 14 are connected by the transmission line 5. Because the transmission plug 2 14 and the plug board 10 are connected by the connecting line 13, the connection between the detection box 1 and the plug board 10 is realized;

[0037] The left and right sides of the lifting plate 603 are respectively installed with connecting plates 604, the connecting plates 604 are slidably installed in the connecting frame 601, and the two connecting plates 604 are respectively installed with a contact plate 1 606;

[0038] Positioning rods 608 are symmetrically mounted on the bottom surface of the inner cavity of the mounting frame 4 , and a connecting plate 604 is slidably mounted between the two positioning rods 608 .

[0040] A closing frame 113 is installed between the top surfaces of the two closing plates 112, the top surface of the inner cavity of the closing frame 113 contacts the top surface of the closing plate 112, and two contact plates 117 are installed on the outer walls on the left and right sides of the closing frame 113 respectively;

[0041] The side wall of the moving block 115 is connected with a connecting rope 116, and the connecting rope 116 passes through the side wall of the sliding frame 114. The side of the connecting rope 116 away from the moving block 115 is connected with a connecting plate 604;

[0042] The lower part of the side of the contact plate 1 606 close to the closed component 11 is designed to be arc-shaped, and the upper part of the side of the contact plate 1 606 close to the closed component 11 is designed to be flat.

[0043] In a further embodiment, referring to Figure 1 - Figure 7A mounting frame 607 is installed on one side of the top surface of the lifting plate 603, and a positioning assembly 7 is installed on the side of the mounting frame 607 away from the lifting plate 603. The positioning assembly 7 includes a positioning frame 701, and a positioning frame 701 is installed on the bottom surface of the mounting frame 607. A rotating shaft 705 is symmetrically and rotatably installed on the top surface of the positioning frame 701. A rotating wheel 706 is installed on the top surface of the rotating shaft 705. A bevel gear 704 is installed on the bottom surface of the rotating shaft 705. Rotating shafts 702 are rotatably installed on both sides of the inner cavity of the positioning frame 701, and bevel gears 703 are installed on the outer walls of the two rotating shafts 702, respectively. The bevel gear 703 is meshed with the bevel gear 704;

[0044] When testing the relay, the relay is placed between the two clamping plates 712, and then the rotating wheels 706 are rotated to drive the second rotating shaft 705 to rotate, and the transmission of the bevel gear 2 704 and the bevel gear 1 703 drives the threaded rod 1 711 to rotate, thereby adjusting the position of the clamping plate 712, and finally clamping and positioning the relay;

[0045] Furthermore, the side wall of the clamping plate 712 and the inner wall of the positioning frame 701 are in contact with each other to prevent the clamping plate 712 from rotating.

[0046] In a further embodiment, referring to Figure 1 - Figure 7 , a threaded rod 711 is installed on each side of the two rotating shafts 702 close to each other, and a clamping plate 712 is threadedly connected to the threaded rod 711, and the clamping plate 712 is used to clamp the relay;

[0047] A plurality of shifting teeth 707 are evenly distributed on the side wall of the rotating wheel 706, a plurality of through holes 708 are evenly distributed on the top surface of the rotating wheel 706, a plurality of insertion holes 709 are evenly distributed on the top surface of the positioning frame 701, and a plug-in rod 710 is inserted between the insertion holes 709 and the through holes 708;

[0048] Among them, the threaded rod 2 602 is then rotated to drive the lifting plate 603 to move downward and compress the spring 605. When the lifting plate 603 moves downward, the connecting plate 604 and the contact plate 1 606 will also move downward synchronously, and then the arc surface on the side wall of the contact plate 1 606 will push the contact plate 2 117 and the closed frame 113, thereby opening the interior of the closed frame 111. As the contact plate 1 606 continues to descend, the vertical side of the contact plate 1 606 will contact the contact plate 2 117. At this time, the closed frame 113 and the contact plate 2 117 will no longer move, and the positioning component 7 will connect the relay to the plug board 10 for detection under the action of the mounting frame 607 and the lifting plate 603.

[0049] The working principle of the present invention is as follows: when the device is used, the detection box 1 is first powered on through the power interface 9, and then the detection box 1 and the transmission plug 2 14 are connected by the transmission line 5. Since the transmission plug 2 14 and the plug board 10 are connected by the connecting line 13, the connection between the detection box 1 and the plug board 10 is realized;

[0050] When testing the relay, the relay is placed between the two clamping plates 712, and then the rotating wheel 706 is rotated to drive the rotating shaft 2 705 to rotate, and the transmission of the bevel gear 2 704 and the bevel gear 1 703 drives the threaded rod 1 711 to rotate, thereby adjusting the position of the clamping plate 712, and finally clamping and positioning the relay. After the adjustment is completed, the plug-in rod 710 is inserted between the through hole 708 and the insertion hole 709, so as to limit the rotating wheel 706 and ensure the stability of the clamping;

[0051] Then, the threaded rod 602 is rotated to drive the lifting plate 603 to move downward and compress the spring 605. When the lifting plate 603 moves downward, the connecting plate 604 and the contact plate 1 606 will also move downward synchronously. Then, the arc surface on the side wall of the contact plate 1 606 will push the contact plate 2 117 and the closed frame 113, thereby opening the inside of the closed frame 111. As the contact plate 1 606 continues to descend, the vertical side surface of the contact plate 1 606 will contact the contact plate 2 117. At this time, the closed frame 113 and the contact plate 2 117 will not move anymore, and the positioning assembly 7 will plug the relay into the plug board 10 for detection under the action of the mounting frame 607 and the lifting plate 603.

[0052] After the detection is completed, the threaded rod 2 602 is rotated in the opposite direction to drive the lifting plate 603, the connecting plate 604, the contact plate 1 606 and the positioning assembly 7 to rise, thereby separating the relay from the plug board 10. Subsequently, the contact plate 1 606 will not contact the contact plate 2 117. As the lifting plate 603 and the mounting frame 607 continue to rise, the connecting plate 604 will pull the moving block 115 and the closing frame 113 on the moving block 115 to reset, thereby protecting the plug board 10.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
