[0017] S2: When the leg tube fits against the detection elastic piece for detection, and it is judged whether the diode is good through the alarm lamp. While the lower pressing disc presses down, the connecting piece on the surface of the lower pressing disc drives the connecting short column to move inward, and the connecting short column drives the stress long rod to move inward;

[0018] S3: The tightening column pushes the tightening rod to move, the pushing rod pushes the tightening block to make the clamping telescopic rod move backward.

[0019] S4: The U-shaped circular ring drives the tension rod on the surface of the tension column to move upward, the tension rod drives the tension ring to move, and the tension ring drives the anti-falling clamping rod to clamp the diode, effectively clamping the diode to prevent it from falling when the diode detection is completed.

[0020] The present invention has the following beneficial effects:

[0021] The present invention sets up a detection mechanism. First, the diode pin tube to be detected is placed on the surface of the pressing disc and pressed down. When the pressing telescopic rod and the pressing spring on the inner wall of the pressing hole at the bottom of the pressing disc are stressed, they are pressed downwards. The driving piece on the surface of the pressing disc drives the driving rod, the driving rod drives the driving column, and the driving column drives the support rod to make the sliding piece slide inwards on the surface of the slider, so that the tightening ring on the surface of the support rod contracts towards the inner wall of the contraction groove on the surface of the contraction ring. Finally, the anti-slip plate on the surface of the support rod fits the pin tube of the diode to fix it. When the pin tube fits the detection elastic piece for detection, and then it is judged whether the diode is good through the alarm lamp, effectively fixing the pin tube of the diode to prevent misjudgment during the detection process of the diode.

[0022] The present invention sets up a clamping mechanism. When the pressing disc presses down, the connecting piece on the surface of the pressing disc drives the connecting short column to move inwards, the connecting short column drives the stress long rod to move inwards, the stress long rod drives the driving long rod on the inner wall of the U-shaped ring on the surface of the stress ring to move inwards, the stress ring drives the driving round rod to move, and the driving round rod drives the connecting square plate to make the sliding plate slide inwards on the surface of the slide rail. When the stress block touches the diode, the stress block moves backwards by the thrust, the stress block drives the tightening column to move backwards, the tightening column pushes the tightening rod to move, and the pushing rod pushes the tightening block to make the clamping telescopic rod move backwards. At the same time when the tightening column moves backwards, the stress piece on the surface of the tightening column drives the driving long column to make the clamping rod close in the opposite direction to clamp the conductor of the diode, effectively not requiring holding the diode during the detection process, saving manpower.

[0023] The present invention sets up an anti-drop mechanism. When the sliding plate slides, the toothed plate on the surface of the sliding plate drives the rotating gear to rotate, the driving gear drives the threaded rod to rotate. While the threaded rod rotates, it makes the driving ring move downwards, and the driving ring drives the T-shaped plate to move downwards. When the T-shaped plate presses down on the conductor of the diode, the elastic plate moves upwards through the elastic force of the anti-drop telescopic rod and the anti-drop spring. While the elastic plate moves upwards, it drives the anti-drop round plate to move upwards, the anti-drop round plate drives the U-shaped ring on the surface to move, the U-shaped ring drives the tension rod on the surface of the tension column to move upwards, the tension rod drives the tension ring to move, and the tension ring drives the anti-drop clamping rod to clamp the diode, effectively clamping the diode to prevent it from falling when the diode detection is completed.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0050] S2: When the leg tube fits the detection elastic piece 124 for detection, and judges whether the diode is good through the alarm lamp 105. While the pressing disc 116 presses down, the connecting piece 117 on the surface of the pressing disc 116 drives the connecting short column 222 to move inward, and the connecting short column 222 drives the stress long rod 221 to move inward;

[0051] S3: The tightening column 210 pushes the tightening rod 209 to move, and the pushing rod 210 pushes the tightening block to make the clamping telescopic rod 206 move backward. While the tightening column 210 moves backward, the stress piece 212 on the surface of the tightening column 210 drives the driving long column 213 to make the clamping rod 216 close in the opposite direction to clamp the conductor of the diode;

[0052] S4: The U-shaped ring 313 drives the tension rod 315 on the surface of the tension column 314 to move upward. The tension rod 315 drives the tension ring 316 to move.

[0053] During use, first place the lead of the diode to be detected on the surface of the pressing disc 116 and press it down. When the pressing telescopic rod 120 and the pressing spring 121 on the inner wall of the pressing hole at the bottom of the pressing disc 116 are stressed, they press down. The driving piece 115 on the surface of the pressing disc 116 drives the driving rod 114. The driving rod 114 drives the driving column 113.

The stress ring 218 drives the driving round rod 204 to move. The driving round rod 204 drives the connecting square plate 202 to make the sliding plate 201 slide inward on the surface of the slide rail 103.

The tightening column 210 pushes the tightening rod 209 to move. The push rod 210 pushes the tightening block to make the clamping telescopic rod 206 move backward. While the tightening column 210 is moving backward, the stress piece 212 on the surface of the tightening column 210 drives the driving long column 213 to make the clamping rod 216 close in the opposite direction to clamp the conductor of the diode. When the sliding plate 201 slides, the toothed plate 203 on the surface of the sliding plate drives the rotating gear 302 to rotate. The driving gear 302 drives the threaded rod 301 to rotate. While the threaded rod 301 is rotating, it makes the driving ring 305 move downward. The driving ring 305 drives the T-shaped plate 306 to move downward. When the T-shaped plate 306 presses down on the conductor of the diode, the elastic plate 319 moves upward through the elasticity of the anti-drop telescopic rod 310 and the anti-drop spring 311. While the elastic plate 319 is moving upward, it drives the anti-drop round plate 317 to move upward. The anti-drop round plate 317 drives the U-shaped ring 313 on its surface to move. The U-shaped ring 313 drives the tension rod 315 on the surface of the tension column 314 to move upward. The tension rod 315 drives the tension ring 316 to move. The tension ring 316 drives the anti-drop clamping rod 309 to clamp the diode.
