In the preferred embodiment, through the rotational connection between the joint mounting frame 13 and the screw mounting frame 14, the angle adjustment of the grounding turning wire clamp can be realized, so as to be used in more situations, and the applicability is stronger. The locking mechanism 60 can lock the joint mounting frame 13 and the screw mounting frame 14 when the joint mounting frame 13 and the screw mounting frame 14 are rotated to a certain angle, so that the two maintain at a certain angle, such as maintaining at an angle of 90°. Figure 2 or Figure 4 In the example embodiment, the linkage rod 50 is a flexible linkage rod, that is, a flexible linkage rod that can be bent, which can be adjusted with the angle adjustment of the joint mounting frame 13 and the screw mounting frame 14, and can keep the rotation of the joint 20 transmitted to the rotating screw 30. In an example embodiment, the linkage rod 50 is a steel strand or a steel wire tight spiral ring winding formed into a cylindrical structure, etc., to form a flexible structure that can transmit the rotation of the joint 20.

[0036] The screw mounting frame 14 is circumferentially provided with a plurality of positioning holes 15 at equal intervals around the rotation point, and the joint mounting frame 13 is provided with a guide hole 16, and when the joint mounting frame 13 and the screw mounting frame 14 are rotated to a certain position, the guide hole 16 can be aligned with one of the positioning holes 15. In the exemplary embodiment, there are eight positioning holes 15, which are circumferentially distributed and concentric with the rotation point (rotation shaft) between the joint mounting frame 13 and the screw mounting frame 14.

[0037] In the preferred embodiment, as shown in Figure 3 The locking mechanism 60 includes a fixed housing 61, a movable frame 62, a button 63, a fixed sleeve 64, a movable rod 65, a movable block 66, and a resilient member 67. The fixed housing 61 is fixedly installed on the joint mounting frame 13, the fixed sleeve 64 is fixedly installed on the joint mounting frame 13 and aligned with the guide hole 16, the fixed sleeve 64 is located in the fixed housing 61, and the movable rod 65 is slidingly arranged in the fixed sleeve 64 and the guide hole 16, so that when the guide hole 16 is aligned with one of the positioning holes 15, the movable rod 65 can enter the positioning hole 15, at this time, the movable rod 65 is located in the guide hole 16 and the positioning hole 15 at the same time, so that the joint mounting frame 13 and the screw mounting frame 14 cannot be rotated, that is, the angle between the joint mounting frame 13 and the screw mounting frame 14 is maintained. The movable frame 62 is movably arranged in the fixed housing 61, the button 63 is fixedly connected with the movable frame 62 and protrudes out of the fixed housing 61, so that when the button 63 is pressed into the fixed housing 61, it can drive the movable frame 62 to move inward, that is, to move in the direction of the fixed sleeve 64. The resilient member 67 is a compression spring, which is located between the movable frame 62 and the movable rod 65 to have a tendency to drive the movable rod 65 to extend out of the guide hole 16 in the direction of the screw mounting frame 14 so as to enter one of the positioning holes 15, that is, through the resilient member 67, in the state that the button 63 is not pressed, the movable frame 62 is pressed against the inner wall of the fixed housing 61, and the movable rod 65 has a tendency to extend out of the guide hole 16 in the direction of the screw mounting frame 14, and when one of the positioning holes 15 is aligned with the guide hole 16, the end of the movable rod 65 can enter the positioning hole 15, at this time, the rotation between the joint mounting frame 13 and the screw mounting frame 14 is limited, the angle between the joint mounting frame 13 and the screw mounting frame 14 is maintained, that is, the locking of the joint mounting frame 13 and the screw mounting frame 14 is achieved. It can be understood that when the movable rod 65 presses the resilient member 67, the movable rod 65 can also come out of the positioning hole 15, at this time, the joint mounting frame 13 and the screw mounting frame 14 can be rotated again to realize the adjustment of the angle between the joint mounting frame 13 and the screw mounting frame 14, that is, the adjustment of the angle of the grounding turn bend clamp is realized. The way of limiting the rotation of the joint mounting frame 13 and the screw mounting frame 14 by the movable rod 65 is not easy to loosen or slide during operation, which can well maintain the angle of the grounding turn bend clamp and avoid safety accidents.

[0038] The movable rod 65 has a through-slot 68 on both sides, which is higher at one end and lower at the other with a smooth transition. The fixed sleeve 64 has a guide groove 610 at the position corresponding to the openings on both sides of the through-slot 68. The guide groove 610 passes through both sides of the fixed sleeve 64 and is level at both ends. The movable frame 62 has guide blocks 69 at the openings on both sides of the through-slot 68. The bottom of the guide block 69 corresponding to the higher opening of the through-slot 68 is set with a higher position closer to the through-slot 68 and a lower position further away from the through-slot 68. The top of the guide block 69, which is located at the lower opening position of the inclined groove 68, is provided with an inclined surface that is lower near the inclined groove 68 and higher away from the inclined groove 68. The middle part of the movable block 66 passes through the inclined groove 68 and is inclined accordingly. The two ends of the movable block 66 are respectively provided with transmission blocks 611. The movable block 66 is located outside the inclined groove 68. The transmission blocks 611 abut against the inclined surfaces of the guide blocks 69 on both sides and abut against the upper and lower walls of the guide groove 610. In practice, when button 63 is pressed, the movable frame 62 moves inward, and the guide block 69 moves inward together, pressing the transmission block 611 through the inclined surface that is higher near the inclined groove 68 and lower away from the inclined groove 68. Since the transmission block 611 abuts against the upper and lower walls of the guide groove 610, and the middle part of the movable block 66 matches and passes through the inclined groove 68, the movable block 66 slides to the lower side of the middle part, and the corresponding movable rod 65 is pressed and compresses the elastic element 67 to move towards the button 63. At this time, the movable rod 65 can come out from the positioning hole 15, and the connector mounting bracket 13 and the lead screw mounting bracket 14 can rotate to realize the connection between the connector mounting bracket 13 and the lead screw mounting bracket 14. The angle adjustment between the screw mounting brackets 14 allows for the adjustment of the grounding turning clamp angle. Releasing button 63, under the reset action of elastic element 67, causes the movable rod 65 to tend to extend out of the guide hole 16 towards the screw mounting bracket 14. When one of the positioning holes 15 aligns with the guide hole 16, the end of the movable rod 65 can enter the positioning hole 15, thus restricting the rotation between the connector mounting bracket 13 and the screw mounting bracket 14 and maintaining the angle between them. During the reset movement of the movable rod 65, the movable block 66 can be driven to reset to the other side, and the movable bracket 62 also resets, as does button 63. In this embodiment, pressing the button unlocks the locking of the connector mounting bracket 13 and the screw mounting bracket 14, allowing rotation between them and enabling the adjustment of the grounding turning clamp angle. Releasing the button locks the connector mounting bracket 13 and the screw mounting bracket 14, fixing the angle of the grounding turning clamp. This method is simple and quick to operate, maintains the angle of the grounding bend clamp, and is less prone to failure when locked.

[0039] In one exemplary embodiment, a grounding wire device is also provided, please refer to Figure 5The device comprises the grounding turn-around wire clamp of the above-mentioned embodiments, and further comprises an insulating rod 70 on an electric tool (such as an electric push rod, etc., not shown in the figure), which is connected with the joint 20 of the grounding turn-around wire clamp.

[0040] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
