[0035] When in use, the product is clamped and fixed by the clamping plates 17 inside the two movable plates 11, and then the motor is started, which drives the threaded rod 9 to rotate, so that the two movable plates 11 move downward, and drive the product to move downward. At this time, when the product is placed flatly in the detection groove 3 on the fixture body 1, the multiple detection needles 4 in the detection groove 3 will pass through the holes opened on the product. At this time, the rubber nail 5 will be pressed downward by the product, so that the movable contact switch 6 moves downward and contacts with the fixed contact switch 7, thereby making an alarm light 2 on the fixture body 1 light up green, and the speaker emits a voice broadcast, which is Good products, on the contrary, when the product with few holes cannot be put into the detection slot 3 on the fixture body 1, the glue nail 5 cannot be pressed downward. At this time, another alarm light 2 lights up red, and the speaker makes a voice broadcast, which is a defective product, so that the good and defective products in the product can be quickly detected, which is convenient for the staff to deal with the defective products. Then, when the product is inspected, the motor drives the threaded rod 9 to reverse, so that the product moves upward and separates from the detection slot 3. At this time, the glue nail 5 is reset under the elastic force of the reset spring 8, and drives the movable contact switch 6 to separate from the fixed contact switch 7, which is convenient for the next detection and use.

[0036] Embodiment 2: Different from Embodiment 1, this embodiment utilizes two clamping plates 17 to move relative to each other, so as to clamp and fix the product and prevent the product from shifting.

[0037] The staff places the product between the two movable plates 11. At this time, the staff manually rotates a rotating rod 18 and uses the first pulley assembly to drive the other rotating rod 18 to rotate synchronously. At the same time, the rotating rod 18 uses the bevel gear set to drive the screw 19 to rotate, so that the sleeve 20 drives the clamping plate 17 to move. At this time, the two clamping plates 17 move relative to each other to clamp and fix the product, so that the product can enter the detection slot 3 accurately, avoiding the product from being offset and affecting the detection accuracy. Then, when it is necessary to remove the inspected product, it is only necessary to rotate the rotating rod 18 in the opposite direction to make the screw 19 rotate in the opposite direction, and drive the sleeve 20 and the clamping plate 17 to reset, thereby releasing the clamping of the product.

[0038] Embodiment 3: Different from Embodiment 2, this embodiment uses a suction cup 13 to adsorb and fix the product, further improving the stability of the product during the inspection process. Figure 1 , Figure 3 and Figure 6 As shown, a connecting frame 12 is fixed on the top of the two movable plates 11, and a suction cup 13 is installed inside the connecting frame 12, a piston plate 14 is slidably connected to the inner wall of the suction cup 13, and a piston rod 15 is fixed on the top of the piston plate 14, and gear blocks are installed on the front of the piston rod 15 at equal intervals.
