[0015] Step 1: Unlock the device by rotating the locking block of the locking device of the locking assembly, press the push switch to move backward along the direction of the T-slot and compress spring 2 to contract, and drive the locking plate to rotate and contract back into slot 4 by the push switch moving backward. At this time, move movable column 2 and the rotating handle forward along the direction of slot 3 to unlock the cover of the cover device, and drive the rotating column to rotate in the support column by rotating the cover. Prevent the rotating column from shifting by the limit block. After opening the cover, put the grounding wire on the fixed column on the connector assembly, and rotate the cover to tighten it, then insert movable column 2 into slot 3, and rotate the locking block to lock the cover.

[0016] Step 2: Press the pressing handle of the pressing device of the adjustable pressing clamping assembly to drive the gear to rotate counterclockwise in the square groove, and the counterclockwise rotation of the gear drives the locking tooth of the locking device to lift upward in the slot hole 2, so as not to block the normal counterclockwise rotation of the gear, and the counterclockwise rotation of the gear drives the rack to move downward, and the downward movement of the rack drives the movable column 1 and the limiting slide groove 1 to move downward along the direction of the slide groove. At the same time, the movable column 1 moving downward drives the clamping block of the clamping device to move downward and compresses the spring 2 to contract. When it moves to the appropriate position, the locking of the device is completed by the cooperation of the locking tooth and the gear. When the appropriate locking position is adjusted, the protrusion is pushed upward to drive the slide plate to move upward in the slot hole 1 along the direction of the limiting slide groove 2, and the upward moving slide plate drives the locking tooth and the slot hole 2 to move upward to cancel the locking of the gear, and the pressing handle is pressed by one hand to adjust the distance between the clamping block and the connector.

[0017] Step 3: Move the clamping block downward to open the clamping opening. At this time, move the connector to the left. The high-voltage wire begins to compress the limit column of the limit assembly, driving the rotating shaft to rotate and shrink back into the receiving groove. When the high-voltage wire enters the opening of the clamping block and the connector assembly, the limit column is reset due to gravity. When the limit column remains vertical to the limit column through the obstruction of the receiving groove, it cannot continue to move to the left, thereby blocking the high-voltage wire in the opening of the clamping block and the connector. When the high-voltage wire needs to be taken out, move the clamping block forward to take out the high-voltage wire from the gap between the clamping block and the limit column.

[0018] Beneficial technical effects: the present invention drives the gear to rotate counterclockwise in the square groove by pressing the pressing handle of the pressing device of the adjustable pressing clamping assembly, and the locking tooth of the locking device is lifted upward in the slot hole 2 by the counterclockwise rotation of the gear, so that the normal counterclockwise rotation of the gear is not blocked, and the rack is driven to move downward by the counterclockwise rotation of the gear, and the movable column 1 and the limiting slide groove 1 are driven to move downward along the direction of the slide groove by the downward movement of the rack, and the movable column 1 moving downward at the same time drives the clamping block of the clamping device to move downward and compress the spring 2 to contract, and when it moves to a suitable position, the locking of the device is completed by the cooperation of the locking tooth and the gear, and when the suitable locking position is adjusted, the slider is driven to move upward in the slot hole 1 along the direction of the limiting slide groove 2 by pushing the protrusion upward, and the locking tooth and the slot hole 2 are driven to move upward by the slider moving upward to cancel the locking of the gear, and the distance between the clamping block and the connector assembly is adjusted by pressing the pressing handle with one hand, and when it is adjusted to a suitable clamping position, the locking of the device is released to make it clamped automatically, and it is no longer necessary to manually rotate the locking device, thereby reducing the operation of workers and improving work efficiency.

[0019] The present invention releases the lock of the device by rotating the locking block of the locking device of the locking assembly, and by pressing the pressing switch, it moves backward along the direction of the T-slot and compresses the spring two to contract. The pressing switch that moves backward drives the locking plate to rotate and contract back into the slot hole four. At this time, the movable column two and the rotating handle are moved forward along the direction of the slot hole three to release the lock of the cover plate of the cover plate device, and the rotating cover plate drives the rotating column to rotate in the supporting column. The rotating column is prevented from deviating by the limitation of the limit block. After the cover plate is opened, the grounding wire is sleeved on the connector assembly, and the cover plate is rotated to press it, and then the movable column two is inserted into the slot hole three, and the cover plate is locked by rotating the rotating locking block. All nuts can be opened at one time by opening the locking device, which simplifies the ground wire installation process. At the same time, the nuts at both ends are locked so that they are not easy to fall off.

[0020] The present invention opens the clamping opening by moving the clamping block downward, and at this time moves the connector assembly to the left, and the high-voltage wire begins to compress the limiting column of the limiting assembly, driving the rotating shaft to rotate and shrink back into the receiving groove. When the high-voltage wire enters the opening of the clamping block and the connector assembly, the limiting column is reset due to gravity, and is blocked by the receiving groove when the limiting column remains vertical to the limiting column and cannot continue to move to the left, thereby blocking the high-voltage wire in the opening of the clamping block and the connector assembly. When the high-voltage wire needs to be taken out, the clamping block is moved forward according to the slow motion, so that the high-voltage wire is taken out from the gap between the clamping block and the limiting column. By restricting the high-voltage wire in the grounding device, the high-voltage wire will not fall off the grounding device during the process of clamping the high-voltage wire, the clamping position can be better adjusted, and the grounding device will not fall off the high-voltage wire and injure the staff below.

9. A method for using a combined grounding wire device, characterized in that: The combined grounding wire device according to claim 8 is used, wherein the connector assembly (5) comprises a connector (51) and a fixing column (52), the upper end of the handle (1) is fixedly connected with the connector (51), the lower end of the connector (51) is provided with a slide groove (212), the upper inner wall of the connector (51) is provided with a storage groove (44), the upper inner wall of the connector (51) is in contact with the clamping block (231), the right front wall of the connector (51) is fixedly connected with two supporting columns (312) and a plurality of connectors (51), and the connector (51) is located on the right side of the supporting column (312); the grounding method is: Step 1: The locking device is unlocked by rotating the locking block (323) of the locking device (32) of the locking assembly (3), and the pressing switch (328) is pressed to move backward along the direction of the T-shaped slot (326) while compressing the second spring (327) to contract. The pressing switch (328) that moves backward drives the locking plate (324) to rotate and contract back into the fourth slot (325). At this time, the movable column (322) and the rotating handle (329) are moved forward along the direction of the third slot (321) to release the cover device. The cover plate (311) of the connector (31) is locked, and the rotating column (314) is driven to rotate in the support column (312) by the rotating cover plate (311). The rotating column (314) is prevented from deflecting by the restriction of the limit block (313). After the cover plate (311) is opened, the grounding wire is sleeved on the fixed column (52) on the connector assembly (5), and the cover plate (311) is rotated to press it, and then the movable column (322) is inserted into the slot hole (321), and the rotating locking block (323) is rotated to lock the cover plate (311); Step 2: By pressing the pressing handle (211) of the pressing device (21) of the adjustable pressing clamping assembly (2), the gear (214) is driven to rotate counterclockwise in the square groove (217). The counterclockwise rotation of the gear (214) drives the locking tooth (222) of the locking device (22) to lift upward in the second slot (223), thereby not blocking the normal counterclockwise rotation of the gear (214). The gear (214) is driven to rotate counterclockwise to drive the rack (215) downward. The rack (215) moves downward to drive the movable column (213) and the limiting slide groove (216) to move downward along the direction of the slide groove (212). At the same time, the movable column (213) that moves downward is driven by the movable column (213) with the movable column (213) moving downward. The clamping block (231) of the movable clamping device (23) moves downward and compresses the second spring (232) to contract. When it moves to a suitable position, the locking tooth (222) cooperates with the gear (214) to complete the locking of the device. When the suitable locking position is adjusted, the protrusion (225) is pushed upward to drive the slide plate (226) to move upward in the slot hole 1 (221) along the direction of the second limiting slide groove (224). The upwardly moving slide plate (226) drives the locking tooth (222) and the second slot hole (223) to move upward to cancel the locking of the gear (214). The distance between the clamping block (231) and the connector (51) is adjusted by pressing the pressing handle (211) with one hand. Step 3: The clamping opening is opened by moving the clamping block (231) downward, and the connector (51) is moved to the left. The high-voltage wire begins to press the limiting column (41) of the limiting assembly (4), driving the rotating shaft (42) to rotate and shrink back into the receiving groove (44). When the high-voltage wire enters the opening between the clamping block (231) and the connector assembly (5), the limiting column (41) is reset due to gravity. When the limiting column (41) is blocked by the receiving groove (44), it cannot continue to move to the left when it remains vertical to the limiting column (41), thereby blocking the high-voltage wire in the opening between the clamping block (231) and the connector (51). When the high-voltage wire needs to be taken out, the clamping block (231) is moved forward slightly so that the high-voltage wire is taken out from the gap between the clamping block (231) and the limiting column (41).
