Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1 to 2, the utility model discloses a guide arm 1 and cover are established in the guide arm 1 outside and can be along the gliding press hammer 2 of guide arm 1, lie in press hammer 2 below on the guide arm 1 and be equipped with pressure disk 3, press hammer 2 to be used for the free fall and strike pressure disk 3. The bottom end of the guide rod 1 is provided with a contact probe 4 which is inserted into the test soil, and the contact probe 4 is conical. A wireless pressure sensor 5 is arranged between the touch probe 4 and the guide rod 1, and the wireless pressure sensor 5 is used for acquiring pressure data of the guide rod 1 to the touch probe 4.
