In the present embodiment, the clutch mechanism 30 includes a connecting shaft 31 and a clutch member 32, the connecting shaft 31 is rotatably connected to the pressing mechanism 20; the hold-down mechanism 20 has a mounting hole 211 for accommodating the clutch member 32, the clutch member 32 is movably disposed in the mounting hole 211 and has a coupling position and a release position, when the clutch mechanism 30 is in the coupling state, as shown in fig. 6 and 7, the clutch member 32 is located at the coupling position, a part of the clutch member 32 extends from the mounting hole 211 to the connecting shaft 31, i.e., a part of the clutch member 32 is located in the mounting hole 211, and another part is located in the connecting shaft 31, when the connecting shaft 31 rotates, the torsional force of the connecting shaft 31 is transmitted to the hold-down mechanism 20 through the clutch member 32, thereby driving the hold-down mechanism 20 to rotate around its axis, so that the hold-down mechanism 20 compresses or releases the ground member 60; when the clutch mechanism 30 is in the disengaged state, as shown in fig. 3 and 4, the clutch member 32 is located at the disengaged position, and at this time, the clutch member 32 is completely retracted into the mounting hole 211, the torsional force is no longer transmitted between the clutch member 32 and the connecting shaft 31, and the rotation of the connecting shaft 31 only makes it idle relative to the hold-down mechanism 20 and cannot drive the hold-down mechanism 20 to rotate, and the grounding member 60 cannot be released.

In this embodiment, the clutch mechanism 30 further includes an operating element 33, the operating element 33 is in a rod shape, at least a portion of the operating element 33 is made of an insulating material so as to be convenient for a handheld operation, one end of the operating element 33 is rotatably connected with the connecting shaft 31 through a rotating shaft, and is also abutted against the clutch element 32, and the operating element 33 mainly plays three roles: first, as a component for driving the clutch member 32, the operating member 33 presses the clutch member 32 when rotating about the rotational axis, thereby moving the clutch member 32 between the engaged position and the disengaged position; secondly, as a component matched with the ground wire head 40 in a stop way, when the ground wire head 40 is arranged on the pile body 10 in a penetrating way, the ground wire head 40 is positioned on the moving path of the operating part 33, and at the moment, the ground wire head 40 can block the operating part 33 from rotating around the rotating shaft, so that the clutch element 32 is kept at a separation position; thirdly, as the part of the manual operation of the operator, when the ground wire pile 60 needs to be released, after the operator removes the ground wire head 40, the operator rotates the operation part 33 manually for the first time, so that the operation part 33 presses the clutch part 32 to move to the combining position, then rotates the operation part 33 for the second time, and the torsional force of the operation part 33 is transmitted to the pressing mechanism 20 to drive the pressing mechanism 20 to move, thereby releasing the ground wire pile 60 and removing the ground wire pile.

In order to ensure that the operating element 33 can achieve the first function, the operating element 33 has at least two pressing surfaces which can be pressed in contact with the clutch element 32, in this embodiment, two pressing surfaces are provided, and the distance between the two pressing surfaces and the rotating axis of the operating element 33 around the rotating shaft is different, the two pressing surfaces can be respectively matched with the clutch element 32 by rotating the operating element 33 around the rotating shaft, the distance that the clutch element 32 can move is different because the distance between the two pressing surfaces and the rotating axis of the operating element 33 around the rotating shaft is different, when the pressing surface with the small distance between the operating element 33 and the rotating axis of the rotating shaft is matched with the clutch element 32, the moving range of the clutch element 32 is large, the clutch element can move into the connecting shaft 31 and also move to the combining position, when the pressing surface with the large distance between the operating element 33 and the rotating axis of the rotating shaft is matched with the clutch, the clutch member 32 has a small range of movement and cannot move into the coupling shaft 31, and is maintained in the disengaged position.

Preferably, the pressing surfaces include end surfaces at the end of the operation member 33 and side surfaces at both sides of the operation member 33, and the distance from the end surfaces to the rotation axis of the operation member 33 about the rotation axis is smaller than the distance from the side surfaces to the rotation axis of the operation member 33 about the rotation axis, as shown in fig. 3 and 6. Thus, when the side of the operating member 33 is engaged with the clutch member 32, the axis of the operating member 33 is perpendicular to the axis of the hold-down mechanism 20, and the axis of the ground lug 40 is parallel to the operating member 33; when the end surface of the operating member 33 engages the clutch member 32, the axis of the operating member 33 is parallel to or even coincident with the axis of the hold-down mechanism 20. It should be noted that, when removing the ground pile, the rotation axes of the two rotations of the operation member 33 are different, when the ground terminal 40 is removed and the operation member 33 is rotated for the first time so that the end surface of the operation member 33 is engaged with the clutch member 32, the operation member 33 is rotated around the rotation axis until the axis of the operation member 33 is parallel to the axis of the connecting shaft 31, and when the pressing mechanism 20 is rotated by rotating the operation member 33 for the second time, the operation member 33 is rotated along its own axis, that is, along the rotation axis of the pressing mechanism 20.

Of course, it is also possible to make the distance from the end surface to the axis of rotation of the operating member 33 greater than the distance from the side surface to the axis of rotation of the operating member 33, when the axis of the operating member 33 is parallel to the coupling shaft 31, i.e. when the end surface engages the clutch member 32, the clutch member 32 is in the disengaged position, and when the axis of the operating member 33 is perpendicular to the coupling shaft 31, i.e. when the side surface engages the clutch member 32, the clutch member 32 is in the engaged position. Accordingly, the direction of the ground stub 40 also needs to be reset.

In the present embodiment, the connecting shaft 31 has a connecting hole 311 opened in the axial direction, at least a portion of the pressing mechanism 20 extends into the connecting hole 311, the connecting shaft 31 further has a through groove 312 opened in the radial direction, a portion of the operating member 33 is located in the through groove 312, the through groove 312 is communicated with the connecting hole 311, and the clutch member 32 can extend into the through groove 312 and contact and press with the side wall of the through groove 312. Since the clutch member 32 of the present embodiment has a prism shape, the mounting hole 211 is also formed as a polygonal long hole, and the transmission of the torsional force is realized by the contact engagement between the side edge of the clutch member 32 and the mounting hole 211 and the through groove 312. One end of the operating part 33 is flat, the size of the flat is close to that of the through groove 312, and the flat extends into the through groove 312 and is connected through the rotating shaft, so that the operating part 33 can rotate around the rotating shaft and can drive the connecting shaft 31 to rotate along the axis of the operating part.

In the present embodiment, the clutch mechanism 30 further includes an elastic member 34, the elastic member 34 is preferably a spring, the elastic member 34 is disposed in the mounting hole 211, and both ends of the elastic member 34 are respectively abutted against the mounting hole 211 and the clutch member 32, the elastic member 34 provides the clutch member 32 with an elastic force moving to the engaging position, so that the clutch member 32 is always abutted against the operating member 33, when the end surface of the operating member 33 rotates to face the clutch member 32, the clutch member 32 moves to the engaging position under the driving of the elastic member 34, and when the side surface of the operating member 33 rotates to face the clutch member 32, the side surface of the operating member 33 presses the clutch member 32 and compresses the spring, so that the clutch member 32 moves to the disengaging position again.

In this embodiment, the pressing mechanism 20 includes a screw 21 and a pin 22, the screw 21 is in threaded engagement with the pile 10, the screw 21 has a mounting hole 211, and when the clutch mechanism 30 drives the screw 21 to rotate, the screw 21 will move back and forth on the pile 10. The circumferential surface of the screw 21 is provided with a ring groove 212, the pin 22 radially passes through the connecting shaft 31, and one end of the pin 22 extends into the ring groove 212 and moves in the ring groove 212, so that the screw 21 is axially positioned.

Optionally, since the contact area of the screw 21 is smaller, in order to increase the contact area between the pressing mechanism 20 and the grounding piece 60, the pressing mechanism 20 further includes a pressing plate 23, the pressing plate 23 is connected to one end of the screw 21 away from the connecting shaft 31, the pressing plate 23 and the screw 21 may be connected through additional components such as a screw, a clamping plate, and the like, when the screw 21 is driven by the connecting shaft 31 to move axially, the pressing plate 23 moves towards a direction close to or away from the grounding piece 60, so as to cooperate with the pile body 10 to press or release the grounding piece 60.

As shown in fig. 1, the pile body 10 includes a first plate 11, a second plate 12 and a third plate 13, and the ground wire head 40 is arranged on the first plate 11; the pressing mechanism 20 is arranged on the second plate 12 in a penetrating way; the third plate 13 cooperates with the pressing mechanism 20 to form a receiving area for pressing the grounding member 60, the second plate 12 and the third plate 13 are both connected to the first plate 11, and the second plate 12 and the third plate 13 are spaced apart from each other.
