The technical scheme adopted by the utility model is as follows: the utility model comprises a needle plate module and an upper needle block, wherein the upper needle block is provided with a mounting hole, a product to be tested is adapted in the mounting hole, a plurality of probes are arranged on the needle plate module, the upper needle block is in floating connection with the needle plate module, and after the upper needle block is pressed down, the probes penetrate into the mounting hole to be contacted with a terminal of the product to be tested.

Further, the needle plate module comprises a middle needle plate and a lower needle plate, the upper needle block is in floating connection with the middle needle plate, the probe is arranged on the middle needle plate, and the middle needle plate is arranged on the lower needle plate.

Further, the upper needle block is connected with the middle needle plate through a plurality of springs.

Further, the middle needle plate is connected with the lower needle plate through a plurality of screws.

Further, the upper needle block is further provided with two arc-shaped grooves, and the two arc-shaped grooves are respectively located on two sides of the mounting hole.

Further, the needle plate module is provided with a plurality of positioning pins.

Further, the head of the probe is conical.

Further, the tail of the probe is in a pointed cone shape.

The beneficial effects of the utility model are as follows: the probe is in a floating state in the initial state, the probe is in a protection area, the flip cover is turned down and buckled in place after the motor is installed in the clamp, at the moment, the motor contacts the upper probe block and applies pressure downwards, the upper probe block drops and exposes the probe, so that the probe contacts a motor terminal after penetrating into the mounting hole, signal conduction is completed, the operation is simple, convenient and rapid, and the working efficiency is greatly improved. In addition, in the lamination process, the spring plays a role in buffering, can absorb the downward pressure, and prevents the probe from being damaged.
