[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present utility model, Figure 1 As shown, the device body 1 is in use. At this time, the inverted cone head of the support rod 8 is inserted into the inside of the foundation surface, thereby fixing the auxiliary guide cylinder 6. At the same time, the lower end of the foundation detection rod 2 is inside the auxiliary guide cylinder 6, the inverted cone head of the foundation detection rod 2 is in contact with the foundation surface, and the lifting locking button 5 is threadedly engaged with the lifting hammer column 3 and moved to the left, so that the lifting locking button 5 moves to the left and disengages from the insertion hole of the foundation detection rod 2. The state is as shown in FIG. Figure 2 As shown, the lifting lock button 5 releases the stop on the lifting hammer column 3, allowing the lifting hammer column 3 to move upward. When the foundation bearing capacity is tested, the lifting grip rod 4 is held to lift the lifting hammer column 3 upward. Figure 4As shown, the hand holding the lifting gripping rod 4 is then released, and the lifting hammer column 3 is allowed to fall and hammer the foundation detection rod 2, so that the foundation detection rod 2 is inserted into the foundation by hammering. Thus, the foundation bearing capacity can be calculated by the sum of the weight of the lifting hammer column 3, the lifting gripping rod 4 and the lifting locking button 5, the number of hammering times of the lifting hammer column 3, the distance between the lifting hammer column 3 and the hammered position of the foundation detection rod 2, and the length of the foundation detection rod 2 inserted into the foundation. The calculation formula is R=(0.8×N-2)×9.8; when Figure 1 As shown, when the device body 1 is folded and carried, the lifting lock button 5 is rotated to engage with the lifting hammer column 3 thread and move to the right, so that the lifting lock button 5 moves to the right and is inserted into the insertion hole of the foundation detection rod 2. The state is as follows Figure 6 As shown, the lifting lock button 5 stops the lifting hammer column 3, and then the auxiliary guide cylinder 6 is moved upward along the foundation detection rod 2. At the same time, the support rod 8 is turned downward and erected, so that the inverted conical head of the support rod 8 is inserted into the conical groove of the foundation detection rod 2. The state is as shown in FIG. Figure 6 As shown, thereby preventing the placement support rod 8 from being displaced, and then rotating the stowage constraint cylinder 7 to engage with the auxiliary guide cylinder 6 threadedly, so that the stowage constraint cylinder 7 is lowered through the threaded engagement, and the stowage constraint cylinder 7 is lowered to cover the flip position of the placement support rod 8 and the auxiliary guide cylinder 6, thereby preventing the placement support rod 8 from flipping by stowing the constraint cylinder 7. The state is as shown Figure 5 As shown, the user can then hold the handle of the foundation detection rod 2 to carry and move the device body 1.

[0032] Example 2:

[0033] The difference from the first embodiment is that the outer circumferential surface of the lifting gripping rod 4 can also be set to a frosted surface, thereby increasing the friction between the outer circumferential surface of the lifting gripping rod 4 and the hand, preventing the lifting gripping rod 4 from slipping when gripping.

[0034] Example 3:

[0035] The difference from the first embodiment is that the regular hexagonal groove of the lifting gripping rod 4 can also be set as a regular heptagonal groove, so that the lifting gripping rod 4 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the lifting gripping rod 4.
