DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Example 1

[0023] A soil pH value detection device, such as Figure 1-Figure 4 As shown, it includes a hand-held base 1 with a scale ruler, the right side of the hand-held base 1 is a transparent structure, a handle 2 is connected to the right side of the upper part of the hand-held base 1, the handle 2 is provided with a rubber sleeve, a probe 3 for inserting into soil for pH value detection is slidably connected to the hand-held base 1, a first spring 4 is connected between the probe 3 and the inside of the hand-held base 1, a connecting cable 5 is connected to the top of the probe 3, the right end of the connecting cable 5 is connected to an operating handle 6, a protective cover 7 for covering and protecting the bottom end of the probe 3 is connected to the bottom of the hand-held base 1, the protective cover 7 is an elastic structure, and an adjustment mechanism 8 for positioning and adjusting the probe 3 is provided on the hand-held base 1.

[0024] like Figure 1-Figure 5 As shown, the adjustment mechanism 8 includes a guide column 81, and two guide columns 81 that are symmetrical front and back are connected to the left sides of the upper and lower parts of the hand-held seat 1. A locking plate 82 for positioning and limiting the probe 3 is slidably connected between the guide columns 81, and four second springs 83 are connected between the locking plate 82 and the guide column 81. A locking tooth 84 that engages with the locking plate 82 is connected to the left side of the probe 3.

[0025] It should be noted that when performing soil pH value detection, the device can be used for operation. First, the protective cover 7 is pulled off so that the bottom end of the probe 3 is no longer blocked. Then the operator operates the probe 3 by holding the handle 2, and observes the height position of the probe 3 according to the transparent structure on the right side of the hand-held seat 1. At the same time, with the assistance of the scale, the probe 3 is pushed downward by a required distance. When the probe 3 slides downward, the first spring 4 will be compressed by force, and the locking tooth 84 will push the locking plate 82, so that the locking plate 82 slides to the left along the guide column 81 until the probe 3 reaches the specified position. At this time, the locking tooth 84 no longer locks the locking plate 82. The plate 82 is pushed, and the locking plate 82 will slide to the right and reset under the action of the second spring 83, and mesh with the locking tooth 84, thereby locking the probe 3. As the probe 3 is inserted, the probe 3 will detect the pH value of the soil, and the information will be transmitted to the operating handle 6 by relying on the connecting cable 5. The operator can make an intuitive judgment through the operating handle 6. After the detection is completed, the locking plate 82 is pulled to the left, so that the locking tooth 84 is no longer restricted. Under the action of the first spring 4, the probe 3 will slide upward and reset, thereby separating from the soil. Then the locking plate 82 is released, so that the locking plate 82 slides to the right and resets under the action of the second spring 83.

[0026] Example 2

[0027] On the basis of Example 1, Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, it also includes a hanging mechanism 9, which includes a guide slot frame 91. The guide slot frame 91 is connected to the left side of the operating handle 6. A limit plate 92 for clamping with the handle 2 is slidably connected to the guide slot frame 91, and two third springs 93 are connected between the limit plate 92 and the operating handle 6.

[0028] It should be noted that in order to facilitate the storage and placement of the entire device, the handle 2 and the limit plate 92 can be snapped together after use. The specific operation method is to insert the handle 2 into the gap between the limit plate 92 and the guide slot frame 91, so that the handle 2 pushes the limit plate 92, and the limit plate 92 will slide to the left along the guide slot frame 91. The third spring 93 is stretched under the force until the rubber sleeve on the lower side of the handle 2 passes through the gap. At this time, the handle 2 can no longer squeeze the limit plate 92. Under the action of the third spring 93, the limit plate 92 will slide to the right and reset, and cooperate with the guide slot frame 91 to lock the handle 2. At this point, the device is assembled and stored, which is convenient for overall carrying.
