[0028] By arranging the sliding and locking mechanism of the clamping block 31, the clamping wiring terminal on the placement plate 2 can be moved to a position close to the detection mechanism 6 and fixed. At the same time, the wire 311 during testing can also be fixed to prevent loosening due to external force and thus affect the testing result.

[0030] When the wire 311 at the terminal needs to be detected, the terminal is first clamped and fixed on the placement plate 2, and then the positioning rod 32 and the circular cover 33 are pulled upwards, so that the clamping block 31 and the positioning rod 32 are synchronously moved, and at this time the wire 311 to be detected is placed in the detection opening 35.

[0031] As shown in the figure, Figure 3 and Figure 5 As shown in the figure, the clamping test anti-dropping mechanism 3 further comprises a first reset spring 34; the first reset spring 34 is arranged outside the positioning rod 32, one end of the first reset spring 34 is fixed to the end of the clamping block 31, the first reset spring 34 is located in the detection opening 35, and the other end of the first reset spring 34 is fixed to the detection opening 35.

[0032] When the wire 311 is inserted into the guide detection opening, the positioning rod 32 is loosened, at this time the positioning rod 32 drives the clamping block 31 and the positioning rod 32 to synchronously move downward under the extension force of the first reset spring 34, until the clamping block 31 presses the guide into the detection opening 35, which can prevent the wire 311 from being pulled out of the outside of the detection opening 35 during detection in the detection opening 35, and thus the wire 311 to be detected can be fixed, preventing the wire 311 from loosening due to external force during detection, thereby affecting the detection result.
