The lifting sleeve 62 is slid in the guide tube 61 to be able to move up and down. The protruding claw piece 64 is set on the lifting sleeve. At the lower end of the barrel 62, a claw portion 641 is formed at the lower end of the protruding claw piece 64 to pass through the extending guide channel 65. An internal thread 621 is formed in the lifting sleeve 62. The driving screw 63 includes a driving head end 631 and An external thread section 632, wherein the driving head end 631 is screwed on the upper cover 30, and a driven part 633 is formed on the driving head end 631, and the external thread section 632 extends downward along the guide cylinder 61 and is screwed together The internal thread 621 in the lifting sleeve 62; thereby when the driving screw 63 rotates in a predetermined direction, the lifting sleeve 62 can be driven down, thereby driving the claw portion 641 of the protruding claw piece 64 to stretch The predetermined length protrudes from the outside of the outer cylinder 20, so that the fixing nail produces a fixing effect.

As shown in Figure 1, in this example, the claws 641 of the protruding claws 64 of each claw driving mechanism 60 protrude from the height position of the wall 23 of the outer cylinder 20, just in line with the helical convex rib 25 The helical path matches with each other, so that the notch 26 is formed at the matching place of the helical convex rib 25 , so that the claw portion 641 of the protruding claw piece 64 is just aligned with the notch 26 .

As shown in Figure 4, in this example, the protruding claw piece 64 is flexible (or called bending elasticity, such as using a stainless steel sheet), and its upper end is connected to the lower end of the lifting sleeve 62. When the lifting sleeve When the cylinder 62 descends, the protruding claw piece 64 will descend along the protruding guide channel 65 and be guided into a deflected shape, and at the same time make the claw portion 641 protrude from the outside of the cylinder wall 23 of the outer cylinder 20 .

As shown in Figure 9, in this example, the protruding claw piece 64B is a rigid arc-shaped piece, and a pivot joint 642 is formed at the upper end to pivotally set on the lower end of the lifting sleeve 62. When the lifting sleeve 62 descends, The protruding claw piece 64B swings with the pivot joint 642 as a fulcrum and descends along the protruding guide channel 65, and at the same time makes the claw portion 641 protrude from the outside of the cylinder wall 23 of the outer cylinder 20 ( as shown in Figure 10).

As shown in Figure 6, in this example, the driving head end 631 of each of the driving screw rods 63 is further formed with a ring flange 634, and the upper cover 30 forms a step-through hole 31 to define and form a diameter-expanding groove 32, the diameter-expanding groove In 32, a lower bearing 81 and an upper bearing 82 arranged at intervals between the upper and lower are assembled, so that the ring flange 634 is sandwiched between the lower bearing 81 and the upper bearing 82, and a ring 83 is placed above the upper bearing 82. Press the limit, and the driven part 633 of the driving head end 631 is exposed in the center of the ring 83, so as to be assembled and driven by a tool (not limited to a conventional tool or a special tool).

Wherein, the lifting sleeve 62 is slidably arranged in the guide cylinder 61 through a linear bearing (note: not shown in the figure). The effect disclosed in this example is mainly to allow the lifting action of the lifting sleeve 62 to be more stable and smooth.

As shown in FIG. 1 , in this example, the conical head 24 at the bottom of the outer cylinder 20 is further formed with a spiral pattern 241 . The type disclosed in this example mainly enables the tapered head 24 to achieve auxiliary guiding and smoother effects during drilling into the soil through the addition of the helical lines 241 .

As shown in FIG. 1 , in this example, the anchor receiving portion 50 is formed on the upper end 11 of the inner tube 10 and protrudes from the upper cover 30 . The fixed nail receiving part 50 shown in Fig. 1 is set in the form of a hexagonal convex column, so that the assembly and driving can be performed by using the known rotary driving handle tool, so as to drive and drill the whole fixed nail into the soil structure .

Wherein, the guide cylinder 61 is formed with a limiting part (note: the drawing omits the label) to abut against the lifting sleeve 62, thereby limiting the maximum stroke of the descending displacement of the lifting sleeve 62. This example reveals the shape characteristics, its effect is mainly to prevent the lifting sleeve 62 from exceeding the set stroke and detaching from the drive screw rod, and the limiting part referred to in the example can specifically be the stop and limit function formed by the shape of the shoulder, or it can be It utilizes the stop and limit effect formed by the curved shape of the protruding guide channel 65 .

By virtue of the above-mentioned structural composition and technical characteristics, the anchor nail with the claw-extending drive mechanism disclosed in the present invention can be used as some ground devices (such as solar photovoltaics) in terms of the preferred embodiment disclosed above in practical application. device, projection light stand or billboard frame, etc.) is intended to be erected on the surface of the soil structure as an embedded pile structure, and the soil structure is not limited to flat ground, but also includes soil terrain such as slopes and upright walls . In its use, first of all, through the morphological characteristics of the fixed nail driven part 50, the known rotary driving handle tool can be used for assembly and driving, so as to drive and rotate the whole fixed nail into the soil structure. After the nail is drilled into the soil structure, as shown in the changes in Figures 4 to 5, we can use the known drive screw 63 to rotate in a predetermined direction to drive the lifting sleeve 62 down, thereby driving the protrusion The claws 641 of the claws 64 protrude out of the outer cylinder 20 by a predetermined length, and as the claws 641 of each protruding claws 64 protrude from the outer cylinder 20 as shown in Figure 7, the fixing nail can be made The state of being embedded in the soil produces an anchoring and stabilizing effect. The present invention adopts the feature of screw feed, which can prevent the protruding claws 64 from automatically retracting during use, thus having better grip and stability benefits, and the protruding claws 64 are stretched outwards. When protruding, the rigidity is excellent, and it has better soil fixation and gripping force, so it has a more practical and stable holding effect, and can avoid environmental protection problems caused by the traditional post-pile grouting method that destroys the environment. In addition, if the present invention is applied to specific environmental fields such as corners, hillsides, etc., it can be determined whether the protruding claws 64 protrude from the side according to the surrounding conditions of the fixing nail, so the fixing force can be flexibly distributed, and the practicability is good.
