The diode is conveniently clamped and disassembled on the clamp block 1. If the thickness of the clamp block 1 is too small, when a worker holds the diode for drilling, the space for downward movement of the hand is limited by the bench drill workbench, and the drilling efficiency is affected. The clamp block 1 is made of an easily-machined material such as an aluminum plate.
The auxiliary positioning groove 10 is a straight groove which penetrates through the clamp block 1 in the thickness direction. The straight groove penetrates the jig block 1 in the thickness direction, and contributes to chip falling.
The auxiliary positioning groove 10 is in clearance fit with the unbanded section on the lead wire. The auxiliary positioning groove 10 is used for positioning and limiting the unbanded section on the lead wire, so that the diode is prevented from rotating along with the drill bit under the cutting force action of the drill bit in the process of punching a lead wire hole.

The flat head positioning groove 11 is a V-shaped groove, the width of the V-shaped groove is larger than that of the flat head of the lead wire, the depth of the V-shaped groove is larger than the diameter of a section, which is not flattened, of the lead wire, and the length of the V-shaped groove is larger than that of the flat head of the lead wire and smaller than that of the auxiliary positioning groove 10. When the positioning device is used, the width of the widest part of the V-shaped groove is larger than the maximum width of the lead flat head, so that the V-shaped groove can position the lead flat heads with different widths. The degree of depth in V-arrangement groove is greater than the diameter of the section of not flattening on the lead wire, and back in putting the V-arrangement groove with the flat head of lead wire flat, the central line of lead wire is located the below of 1 top surface of anchor clamps piece, makes supplementary constant head tank 10 can carry out effective location and spacing to the section of not flattening of lead wire. The length of the V-shaped groove is larger than the maximum length of the lead flat head, so that the V-shaped groove can position the lead flat heads with different lengths.
