[0024] Specifically, during use, the MOS transistor is placed in the placement groove 4 and is located at the bottom of the upper pressing fixture 513. Then, by manually holding the lower pressing handle 508, the lower pressing handle 508 is moved forward, driving the upper pressing fixture 513 to move downward to complete the forming work on the MOS transistor.

[0025] The tops of the two reset springs 504 are fixedly connected to the bottom surface of the moving plate 503, and the bottoms of the two reset springs 504 are fixedly connected to the surface of the base 2.

[0026] Specifically, when manually pressing the lower pressing handle 508, the set reset spring 504 will cause the moving plate 503 to squeeze the reset spring 504. When the lower pressing handle 508 is released, the reset spring 504 will be used to return the lower pressing handle 508 to its original position.

[0027] A through - opening adapted to the two sliding rods 502 is provided inside the moving plate 503, and the two sliding rods 502 are slidably connected to the through - opening.

Rubber pads are fixedly installed on the opposite sides of the two clamping plates 512.

[0030] Specifically, the traction rods 511 play a traction role.
