Four extrusion inclined bars 58 are fixedly installed on the inner wall of the test box body 1, and the two inclined bar movable holes 57 are respectively adapted to the corresponding two extrusion inclined bars 58.

[0027] The driving structure includes a motor 61, which is fixedly mounted on the inner wall of the U-shaped frame 6, and a first pulley 62 is fixedly mounted on the output end of the motor 61. A transmission belt 63 is installed on the first pulley 62 for transmission, and two second pulleys 64 are installed on the transmission belt 63 for transmission. A screw rod 65 is fixedly mounted on one side of the two second pulleys 64, and the two screw rods 65 are rotatably mounted on the test box body 1. The two screw rods 65 are respectively threadedly mounted on the two U-shaped movable seats 5, and the high-voltage wire harnesses of the positive and negative electrodes of the battery are respectively passed through the two first through holes 3, and the wire harnesses are passed through After passing through the first through hole 3, it will be located between the two clamps 55. Then, the motor 61 is turned on to drive the two U-shaped movable seats 5 to slide at the same time. The sliding U-shaped movable seat 5 will make the clamp 55 clamp the wire harness and move along with the U-shaped movable seat 5, so that the moving clamp 55 can straighten the wire harness until the copper nose is located at the second through hole 4 on the top cover 2 after the wire harness is straightened. At this time, the two clamps 55 are located on the side of the copper nose and clamp the wire harness, while the copper nose is located on the top side of the support plate 56. The support plate 56 is used to support the copper nose to prevent the copper nose from shifting during the test.

[0028] In order to realize that the U-shaped movable seat 5 can straighten the wire harness during the movement, two limiting sliding grooves 59 are provided on both sides of the U-shaped movable seat 5, and limiting strips 510 are slidably installed in the four limiting sliding grooves 59, and the four limiting strips 510 are fixedly installed on the inner wall of the test box body 1. The inner wall of the U-shaped movable seat 5 is provided with two movable grooves 511, and extrusion sheets 512 are slidably installed in the two movable grooves 511.

During the movement of the U-shaped movable seat 5, the inclined bar movable holes 57 on both sides will be driven to move in the two extrusion inclined bars 58 respectively. The U-shaped movable seat 5 passes through it, and during the process, the U-shaped movable seat 5 will drive the two sliding rods 52 to move, and when the sliding rod 52 moves, it will drive the roller 54 to contact the extrusion bevel strip 58 through the connecting frame 53. During the continuous movement, the roller 54 will be squeezed by the inclined surface of the extrusion bevel strip 58 and slide horizontally, and the sliding roller 54 will drive the sliding rod 52 to slide in the guide sliding hole 51 through the connecting frame 53, thereby preventing the sliding rod 52 from deviating. The continuously moving sliding rod 52 will drive the clamping plate 55 to move, and during the movement of the clamping plate 55, the two movable rods 513 will be driven to move, so that the moving movable rod 513 drives the extrusion sheet 512 to slide in the movable groove 511, and the extrusion sheet 512 will squeeze the spring 514 while sliding. By arranging two sliding rods 52, clamping plates 55 and other components on the U-shaped movable seat 5, the U-shaped movable seat 5 can make the two clamping plates 55 approach each other during the movement, and the two clamping plates 55 approaching each other will be squeezed on the wiring harness.

[0029] In order to facilitate the control of the U-shaped movable seat 5 to make it move and avoid manual adjustment, a thread hole 66 is opened on the U-shaped movable seat 5, and the screw rod 65 is threadedly installed in the thread hole 66. The output end of the motor 61 will drive the first pulley 62 to rotate. During the rotation of the first pulley 62, it will drive the two second pulleys 64 to rotate through the cooperation with the transmission belt 63, so that the rotating second pulley 64 drives the two screw rods 65 to rotate. During the rotation, the two second pulleys 64 will respectively drive the two U-shaped movable seats 5 to slide simultaneously through the cooperation with the two thread holes 66.

[0030] The working principle is as follows: the high-voltage wire harnesses of the positive and negative electrodes of the battery are passed through the two first through holes 3 respectively. After the wire harnesses pass through the first through holes 3, they will be located between the two clamping plates 55. Then, the motor 61 is turned on. The output end of the motor 61 will drive the first pulley 62 to rotate. During the rotation of the first pulley 62, the two second pulleys 64 will be driven to rotate by cooperating with the transmission belt 63, so that the rotating second pulley 64 drives the two screw rods 65 to rotate. During the rotation, the two second pulleys 64 will respectively drive the two U-shaped movable seats 5 to slide at the same time by cooperating with the two wire holes 66. The sliding U-shaped movable seat 5 will slide on the corresponding limit strips 510 through the limit slide grooves 59 on both sides, thereby adjusting the moving direction of the U-shaped movable seat 5. The U-shaped movable seat 5 will drive the inclined bar movable holes 57 on both sides to pass through the two extruding inclined bars 58 during the movement, and the U-shaped movable seat 5 will drive the two sliding rods 52 to move during the movement, and the sliding rod 52 will drive the roller 54 to contact the extruding inclined bar 58 through the connecting frame 53. During the continuous movement, the roller 54 will be squeezed by the inclined surface of the extruding inclined bar 58 and slide horizontally. The sliding roller 54 will drive the sliding rod 52 to slide in the guide sliding hole 51 through the connecting frame 53, thereby preventing the sliding rod 52 from deviating. The continuously moving sliding rod 52 will drive the clamping plate 55 to move. During the movement of the clamping plate 55, the two movable rods 513 will be driven to move, so that the moving movable rod 513 drives the extruding sheet 512 to move. The clamping plate 55 slides in the groove 511, and the extrusion sheet 512 squeezes the spring 514 while sliding. By arranging two sliding rods 52, clamping plates 55 and other components on the U-shaped movable seat 5, the U-shaped movable seat 5 can make the two clamping plates 55 approach each other during the movement, and the two clamping plates 55 approaching each other will be squeezed on the wire harness, and the U-shaped movable seat 5 will drive the support plate 56 to move during the movement, and under the action of the U-shaped movable seat 5, the clamping plate 55 clamps the wire harness and moves with the U-shaped movable seat 5, so that the moving clamping plate 55 can straighten the wire harness until the copper nose is located at the second through hole 4 on the top cover 2 after the wire harness is straightened. At this time, the two clamping plates 55 are located on the side of the copper nose and clamp the wire harness, and the copper nose is located on the top side of the support plate 56. The plate 56 supports the copper nose to prevent the copper nose from shifting during the test. When in use, the two test pens of the safety tester can be respectively passed through the slots 74 on the two mounting bases 73. After adjusting the height, the corresponding screw rod 75 is rotated. The screw rod 75 moves in the process of rotation by cooperating with the threaded hole 77, so that the moving screw rod 75 drives the rubber stop block 76 to press against the test pen to complete the fixation of the test pen. When testing, the cylinder 71 is turned on to make the output end of the cylinder 71 drive the U-shaped connecting plate 72 to descend. The descending U-shaped connecting plate 72 will slide on the two fixing blocks 79 through the two vertical slide grooves 78, thereby preventing the U-shaped connecting plate 72 from shifting. The continuously descending U-shaped connecting plate 72 will drive the two mounting bases 73 to descend.Thus, the two mounting bases 73 drive the two test pens to extend into the two second through holes 4 respectively, so that the two test pens contact the two copper noses on the positive and negative wiring harnesses of the battery respectively, so as to test the battery. After the test, the motor 61 is controlled to rotate its output end in the opposite direction, so that the U-shaped movable seat 5 can be moved and reset. When the U-shaped movable seat 5 is reset, the roller 54 will be driven to reset. At this time, the roller 54 is no longer squeezed by the squeezing bevel bar 58, and the spring 514 in the compressed state will push the squeezing sheet 512 to move and reset, so that the reset squeezing sheet 512 drives the clamping plate 55 to reset through the movable rod 513, so that the clamping plates 55 on both sides are opened, and the clamping of the wiring harness is cancelled, so that the wiring harness can be taken out for subsequent testing operations.

[0031] Example 2: Figure 1-2 In order to further facilitate the testing work, there is no need to manually operate the test pen to contact the copper nose for testing, so a lifting structure is arranged on the fixed seat 7, and the lifting structure includes a cylinder 71, and the cylinder 71 is fixedly mounted on the inner wall of the fixed seat 7, and the output end of the cylinder 71 passes through the fixed seat 7 and is fixedly mounted with a U-shaped connecting plate 72, and the U-shaped connecting plate 72 is slidably mounted on the fixed seat 7, and mounting bases 73 are fixedly mounted on both sides of the U-shaped connecting plate 72, and slots 74 are provided on the two mounting bases 73, and screw rods 75 are threadedly mounted on the two mounting bases 73, and rubber blocks 76 are fixedly mounted on one end of the two screws 75, and threaded holes 77 are provided on the inner wall of the mounting base 73, and the screw rods 75 are threadedly mounted in the threaded holes 77, and the rubber blocks 76 are movably mounted in the threaded holes 77, and vertical slide grooves 78 are provided on the inner walls of the U-shaped connecting plate 72, and fixed blocks 79 are slidably mounted in the two vertical slide grooves 78, and the two fixed blocks 79 are divided into The two test pens of the safety tester are respectively passed through the slots 74 on the two mounting brackets 73. After adjusting the height, the corresponding screw 75 is rotated. The screw 75 will move by cooperating with the threaded hole 77 during the rotation, so that the moving screw 75 will drive the rubber stopper 76 to press against the test pen to complete the fixation of the test pen. During the test, the cylinder 71 is turned on to make the output end of the cylinder 71 drive the U-shaped connecting plate 72 to descend. The descending U-shaped connecting plate 72 will slide on the two fixed blocks 79 through the two vertical slide grooves 78, thereby preventing the U-shaped connecting plate 72 from deviating. The continuously descending U-shaped connecting plate 72 will drive the two mounting brackets 73 to descend, so that the two mounting brackets 73 respectively drive the two test pens to extend into the two second through holes 4, so that the two test pens are respectively in contact with the two copper noses on the positive and negative electrode wiring harnesses of the battery, so as to test the battery.
