A pair of fixed cavities 5-11 are provided inside the rear shell 3.

[0033] In this embodiment, to achieve the effect of storing the detection pen and the wire into the rear shell 3 and the secondary shell 4, a storage and retraction assembly 5 is designed. Two fixing plates 5-1 are arranged inside the rear shell 3. Two rotating shafts 5-2 and a transmission wheel 5-3 are rotatably connected between the fixing plates 5-1 and the rear shell 3. The transmission wheels 5-3 are connected by a belt drive, allowing the two rotating shafts 5-2 to rotate synchronously. A circular tube 5-4 is provided on the surface of the fixing plate 5-1. The circular tube 5-4 is rotatably fitted onto the outside of the rotating shafts 5-2, and a circular plate 5-5 is provided at one end. The wire can be wound around the outside of the circular tube 5-4 and held between the circular plate 5-5 and the fixing plate 5-1. The upper end of the circular plate 5-5 is provided with… The long plate 5-6 has an elongated hole 5-7 through which the wire passes. When the rotating shaft 5-2 drives the circular plate 5-5 to rotate, the wire in the elongated hole 5-7 can be wound around the circular tube 5-4, which remains fixed. The rear shell 3 has two fixed cavities 5-11 inside. After the wire is retracted, the test pen will be pulled into the fixed cavity 5-11.
