[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1-4 As shown, the utility model provides a test probe, including a probe body 1, the top of the probe body 1 is provided with an adjustment mechanism 2 for increasing the usable length, the surface of the probe body 1 is provided with an insertion mechanism 4 for assisting insertion testing, and the top of the outer side of the probe body 1 is provided with a foot-stepping mechanism 3 for stepping testing.

[0026] The insertion mechanism 4 can be used to assist in inserting into the soil, and the direction of use can be changed as needed.

[0027] The adjustment mechanism 2 includes a growth component and a handheld component. The growth component is arranged at the top end of the probe body 1, and the handheld component is arranged at the top of the growth component.

[0028] The cooperation of the growth component and the handheld component can facilitate people's use and operation.

[0029] The pedal mechanism 3 includes a support component and an adsorption component. The support component is arranged on the outside of the probe body 1 , and the adsorption component is arranged on the top of the outside of the probe body 1 .

[0030] Through the cooperation of the support component and the adsorption component, the downward operation can be achieved by pressing down with the foot, which is beneficial to improving the efficiency of detection and testing.

[0031] like Figure 2 As shown, the extension component includes a first external threaded joint 21, which is fixedly installed on the top of the probe body 1. The outer thread of the first external threaded joint 21 is connected to a growth tube 22. The top and bottom ends of the growth tube 22 are both provided with internal threaded holes 23 to facilitate the extension to the required length.

[0032] like Figure 2 As shown, the handheld assembly includes a second externally threaded joint 24, which is threadedly connected to the top of the inner cavity of the growth tube 22. A holding rod 25 is fixedly installed on the top of the second externally threaded joint 24, and both ends of the outer side of the holding rod 25 are sleeved with anti-slip sleeves 26 to facilitate hand-held downward operation.

[0033] As shown in the figure, it is the initial length growth state. During operation, the growth tube 22 is directly threadedly connected to the probe body 1 through the first external threaded joint 21 through a threaded connection relationship, and then the holding rod 25 is connected to the top of the probe body 1 through the second external threaded joint 24 through a threaded connection relationship.

[0034] In the manual push-down method, the gripping rod 25 is directly held and pushed downward, thereby driving the probe body 1 downward through the extension tube 22 to insert the probe body 1 into the test.

[0035] like Figure 4 As shown, the support assembly includes a connecting frame 32, which is fixedly installed on the outside of the probe body 1. The inner wall of the connecting frame 32 is rotatably connected to a connecting tube 33, and a fixing bar 34 is fixedly installed on the surface of the connecting tube 33 to facilitate support and force, thereby pushing the probe body 1 downward into the ground.

[0036] like Figure 4 As shown, the adsorption component includes a second magnetic block 35 embedded on the top of the fixing bar 34, and a first magnetic block 31 embedded on the top of the outer side of the probe body 1. The first magnetic block 31 and the second magnetic block 35 are magnetically adsorbed, and the required angle can be adjusted when stored, which is convenient for carrying.

[0037] Based on the above, after assembly and installation, the fixing bar 34 is rotated outward. At this time, the fixing bar 34 is magnetically attracted between the second magnetic block 35 and the first magnetic block 31, and the second magnetic block 35 and the first magnetic block 31 are attracted by the principle of opposite poles. When the fixing bar 34 is pulled hard to rotate, the two will separate until they are in the state shown on the left. Then, the foot is stepped on the bottom of the fixing bar 34 to drive the probe body 1 to extend downward and insert.

[0038] When it is necessary to carry it, the fixing bar 34 is rotated to form the state shown on the right side of the figure.

[0039] The insertion mechanism 4 includes a spring plunger 41 and a sleeve assembly. The spring plunger 41 is installed inside the probe body 1, and the sleeve assembly is sleeved on the outside of the probe body 1 to facilitate the insertion of the probe body 1 into the ground.

[0040] As shown in the figure, the insertion component includes a conical tube 42, which is sleeved on the outside of the probe body 1. An adapter hole 43 is opened on the top of one side of the conical tube 42. The spring plunger 41 passes through the conical tube 42 through the adapter hole 43, which is convenient for disassembly and replacement of the required direction.

[0041] When inserted for use, it can be in the state shown in the figure. When it is not needed, the direction of the sharp end of the tapered tube 42 needs to be reversed, from vertically downward to vertically upward. During operation, press the spring plunger 41 to disengage from the tapered tube 42 and the adapter hole 43, then remove the tapered tube 42 and reverse the direction. At this time, press the spring plunger 41 again to enter the inner wall of the tapered tube 42. The tapered tube 42 is sleeved on the outside of the probe body 1 and continues to move upward until the spring plunger 41 passes through the adapter hole 43 and penetrates the tapered tube 42 to form a fixation. At this time, the direction reversal is completed.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
