Among the figure: 1-upper shell, 2-lower house, 3-button, 4-microampere meter, the 5-rotary switch, 6-wiring board, 7-convex tendon, 8-convex tendon, the 9-metal bar that leads, 10-probe stationary seat, 11-probe, 12-step pillar, 13-locatees leg, 14-contact holder, 15-contact, 16-hole, the 17-spring, 18-fixed block, 19-fixed block, 20-guide hole, the 21-hole, 22-metal card base, 23-spring.
Specific embodiments
As shown in Figure 1, probe is the soil testing instrument slidably, and it comprises upper shell 1 and lower house 2, is provided with button 3 in the middle of upper shell 1 and lower house 2 left side walls, and upper shell 1 top is provided with microampere meter 4, and right lower quadrant is provided with rotary switch 5,
As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, be provided with amperometry circuit board 6 below the rotary switch 5, left bottom is provided with convex tendon 7 and convex tendon 8 in the lower house 2, convex tendon 7 is provided with parallel and guiding metal bar 9 and probe stationary seat 10 convex tendon with convex tendon 8 centres, set hole 16 is slippery with guiding metal bar 9 on the probe stationary seat 10, probe stationary seat 10 is provided with probe 11, probe 11 is fixing with probe stationary seat 10 by metal card base 22, fixing back metal card base 22 parts are exposed in probe stationary seat 10 outsides, guiding metal bar 9 two ends are provided with spring 17, and guiding metal bar 9 is fixed on the housing by locating piece 18 and locating piece 19, and locating piece 19 is provided with the guide hole 20 slippery with probe 11.The bottom is provided with two step pillars 12 between lower house 2 left side walls and the convex tendon 7, be equipped with location leg 13 in twos on the step pillar 12, set hole 21 is slippery with step pillar 12 upper end external diameters on the leg 13 of location, table is provided with spring 23 in leg 13 1 ends of location, appearance serves as a contrast on button 3 inside surfaces by spring 23, the most advanced and sophisticated convex tendon 7 right surperficial 1.2-1.5mm that surpass of the other end, lower house 2 bottom convex tendons 8 lower right sides are provided with contact holder 14, contact holder 14 is provided with contact 15, and contact 15 links to each other with amperometry circuit board 6 by lead.
