[0046] Example 1, as Figures 1 to 4 As shown, this utility model provides a fail-safe injection test tool, including: a base plate 1, a test device 101, a moving component, a positioning component, and a protective component;

[0047] The moving and positioning components include:

[0048] A threaded rod 103 is movably embedded inside a rectangular groove 102. A movable plate 106 is movably fitted onto the outer surface of the threaded rod 103. One end of the movable plate 106 is movably embedded inside the rectangular groove 102. The output end of a servo motor 104 passes through the rectangular groove 102 and is fixedly connected to one end of the threaded rod 103. The servo motor 104 can drive the threaded rod 103 to rotate in both directions, thereby driving the movable plate 106 to slide back and forth inside the rectangular groove 102. A U-shaped plate 107 is fixedly installed on the top of the movable plate 106, and the bottom of the U-shaped plate 107 has an opening. The slide 120 has a bidirectional screw 111 movably embedded inside it. Two sliders 112 are movably fitted on the outer surface of the bidirectional screw 111. Insulating clamps 113 are fixedly installed on the top of the two sliders 112. An adjusting wheel 110 is fixedly installed on one end of the bidirectional screw 111. By rotating the bidirectional screw 111 through the adjusting wheel 110, the bidirectional screw 111 can drive the two insulating clamps 113 to move relative to or away from each other through the sliders 112. The adjustment can be made according to the size of the connector of the testing equipment. A triangular plate 114 is fixedly installed on one side of the U-shaped plate 107.

[0049] In this embodiment, the connector of the device to be tested is placed inside the U-shaped plate 107. The adjusting wheel 110 drives the bidirectional screw 111 to rotate. The bidirectional screw 111 drives the insulating clamp 113 to move relative to or away from each other through two sliders 112. The adjustment is made according to the size of the connector to clamp and fix the connector. The insulating clamp 113 can improve safety and prevent the risk of electric shock in case of equipment failure. The servo motor 104 is turned on to drive the threaded rod 103 to rotate. The threaded rod 103 drives the moving plate 106 to move out of the rectangular groove 102. The U-shaped plate 107 is fixedly installed on the top of the moving plate 106. Therefore, the U-shaped plate 107 drives the fixed connector to move, so that the connector is embedded in the interface 108 and connected to the testing device 101. The testing device 101 is used to detect the fault of the device to be tested.

[0050] Example 2, as Figures 1 to 4 As shown, the protective components include:

[0051] Two L-shaped plates 115 are fixedly installed on the outer surface of the testing equipment 101 near the interface 108. Limiting grooves 117 are formed on the opposite surfaces of the two L-shaped plates 115. Limiting blocks 118 are movably embedded inside the limiting grooves 117. Protective plates 119 are fixedly installed on the opposite surfaces of the two limiting blocks 118. The protective plates 119 protect the interface 108, preventing impurities and dust from entering when not in use and affecting the service life of the interface 108. Return springs 116 are fixedly connected to the top of the two L-shaped plates 115. The other end of the return spring 116... Fixedly connected to the top of the protective plate 119, the return spring 116 can drive the protective plate 119 to return to its original position. When not in use, it can block the interface 108. The test device 101 has two positioning grooves 109 on its outer surface near the interface 108. The positioning grooves 109 can embed the triangular plate 114 to improve the stability of the U-shaped plate 107. A telescopic plate 105 is fixedly installed on one side inside the rectangular groove 102. The other side of the telescopic plate 105 is fixedly connected to the moving plate 106. The telescopic plate 105 can be adjusted to extend and retract with the moving plate 106.

[0052] In this embodiment, the U-shaped plate 107 drives the triangular plate 114 to move, so that the triangular plate 114 contacts the inclined groove 121 opened at the bottom of the protective plate 119. The movement of the triangular plate 114 can push the protective plate 119 to move upward through the limiting block 118 inside the limiting groove 117, so that the protective plate 119 no longer protects the interface 108. The triangular plate 114 is embedded inside the positioning groove 109, so that the connector is embedded inside the interface 108. The positioning groove 109 can improve the stability of the U-shaped plate 107. After the triangular plate 114 moves out of the positioning groove 109, the protective plate 114 is protected. The protective plate 119 is reset under the elastic force of the return spring 116, protecting the interface 108. A telescopic plate 105 is movably embedded inside the rectangular groove 102. One side of the telescopic plate 105 is fixedly installed inside the rectangular groove 102, and the other side is fixedly connected to the movable plate 106. The telescopic plate 105 can be extended and retracted with the movable plate 106. The telescopic plate 105 can protect and block the threaded rod 103 inside the rectangular groove 102, preventing the wire connected to the connector from getting stuck inside the rectangular groove 102, thus improving safety.

[0053] Working principle: The connector of the device to be tested is placed inside the U-shaped plate 107. The adjusting wheel 110 drives the bidirectional screw 111 to rotate. The bidirectional screw 111 drives the insulating clamp 113 to move relative to or away from each other through two sliders 112. The adjustment is made according to the size of the connector to clamp and fix the connector. The insulating clamp 113 can improve safety and prevent the risk of electric shock in case of equipment failure. The servo motor 104 is turned on to drive the threaded rod 103 to rotate. The threaded rod 103 drives the moving plate 106 to move out of the rectangular groove 102. The U-shaped plate 107 is fixedly installed on the top of the moving plate 106. Therefore, the U-shaped plate 107 drives the fixed connector to move, so that the connector is embedded in the interface 108 and connected to the testing equipment 101. The testing equipment 101 is used to detect the fault of the device to be tested.

[0054] The U-shaped plate 107 moves the triangular plate 114, causing it to contact the inclined groove 121 at the bottom of the protective plate 119. The movement of the triangular plate 114 pushes the protective plate 119 upwards within the limiting groove 117 via the limiting block 118, thus removing the protective plate 119 from protecting the interface 108. The triangular plate 114 then embeds itself into the positioning groove 109, allowing the connector to be embedded into the interface 108. The positioning groove 109 improves the stability of the U-shaped plate 107. After the triangular plate 114 moves out of the positioning groove 109, the protective plate 119... 19 is reset under the elastic force of the return spring 116, protecting the interface 108. A telescopic plate 105 is movably embedded inside the rectangular groove 102. One side of the telescopic plate 105 is fixedly installed inside the rectangular groove 102, and the other side is fixedly connected to the movable plate 106. The telescopic plate 105 can be extended and retracted with the movable plate 106. The telescopic plate 105 can protect and block the threaded rod 103 inside the rectangular groove 102, preventing the wire connected to the connector from getting stuck inside the rectangular groove 102, thus improving safety.
