then, in the process that an operator rotates the screw rod through the operating rod to push the movable pressing plate to move upwards to press the wire between the upper clamping arm and the movable pressing plate, if careless operation of the operator is not in place, the movable pressing plate does not press the wire, at the moment, as a gap is formed between the movable pressing plate and the wire, the floating rod is not pressed downwards, the ejector rod enables wine to abut against the outer wall of the floating rod, and the limiting column is still inserted into the limiting opening; because the limit post is still inserted into the limit opening, at the moment, if an operator moves the insulating rod downwards, the insulating rod cannot be separated from the inserting post, the insulating rod cannot be detached from the grounding wire hanging device, so that the effect of reminding the operator is achieved, the operator can be aware of the improper operation, the screw rod is further rotated through the operating rod, the movable pressing plate is pushed upwards again, the lead is tightly pressed between the upper clamping arm and the movable pressing plate, when the upper clamping arm and the movable pressing plate clamp the lead, the lower surface of the lead is tightly attached to the upper surface of the movable pressing plate due to the square cross section of the lead, so that the acting force of the first compression spring is overcome, the floating rod is moved downwards through the lower surface of the lead until the upper end of the floating rod is flush with the upper surface of the movable pressing plate, at the moment, the notch of the annular accommodating groove faces the ejector rod, and the ejector rod extends into the annular accommodating groove under the action of the second compression spring, the limiting column is moved out of the limiting opening; therefore, after the lead is tightly pressed between the upper clamping arm and the movable pressing plate, an operator can move the insulating rod downwards to enable the splicing column to move out of the splicing hole in the upper end face of the insulating rod, so that the insulating rod is detached from the grounding wire hooking device; therefore, the pressing self-unlocking type locking mechanism can effectively solve the problem that the ground wire hanging device in the prior art is not in place due to careless operation of operators, the movable pressing plate does not press a wire, the grounding stability is affected due to the fact that the wire clamp is not loose, and potential safety hazards are generated under the condition that the normal use of the ground wire hanging device is not affected.
Specifically, as shown in fig. 4, an inner limiting block 7.10 and an outer limiting block 7.11 are arranged on the inner wall of the transverse guide hole, the sliding column is located between the inner limiting block and the outer limiting block, the outer limiting block is close to the outer wall of the insertion column, the second compression spring is sleeved on the limiting column, and the second compression spring is located between the outer limiting block and the sliding column.
When the floating rod limiting block abuts against the upper end of the axial limiting groove, the distance between the upper end face of the floating rod and the upper surface of the movable pressing plate is 0.5 mm or 1 mm or 1.5 mm.
The upper end of the axial limiting groove extends upwards and is communicated with the top surface of the floating rod, an axial threaded hole coaxial with the floating rod is formed in the upper end of the floating rod, the outer diameter of the axial threaded hole is larger than the inner diameter of the axial guide hole, a threaded sleeve 7.7 is arranged in the axial threaded hole, and the threaded sleeve can be detached from the axial threaded hole. The end surface of the threaded sleeve covers the upper end of the axial limiting groove. The floating rod limiting block is abutted against the upper end of the axial limiting groove, and means that the floating rod limiting block is abutted against the threaded sleeve.
The lower end of the floating rod is provided with a conical guide part with the outer diameter gradually reduced from top to bottom.
Furthermore, the sum of the gravity of the sliding column, the limiting column and the ejector rod is greater than the elastic force of the second compression spring. When the transverse guide holes are vertically distributed and the limiting opening faces the limiting post, the sum of the gravity of the sliding post, the limiting post and the ejector rod overcomes the elastic force of the second compression spring, so that the sliding post moves downwards until the limiting post extends into the limiting opening and abuts against the inner wall of the limiting opening, and at the moment, the ejector rod is completely positioned in the transverse guide holes. When the transverse guide holes are horizontally distributed, the ejector rod is abutted against the outer wall of the floating rod or extends into the annular accommodating groove under the action of the second compression spring. So, at used repeatedly's in-process, can be through being vertical distribution with horizontal guiding hole and place, then, slowly rotate the insulator spindle, when spacing mouthful is facing spacing post, the sliding column moves down, stretch into in the spacing mouth and support the inner wall at spacing mouthful until spacing post, at this moment, the ejector pin is located horizontal guiding hole completely, the floating lever will up-move under first compression spring's effect, support the upper end at the axial spacing groove until the floating lever stopper, so that the upper end of floating lever passes the floating lever via hole and is located the top of the upper surface of activity clamp plate.
The above, only be the utility model discloses a preferred embodiment, it is not right the utility model discloses do any restriction, all according to the utility model discloses the technical entity all still belongs to any simple modification, change and equivalent transformation of doing above embodiment the utility model discloses technical scheme's protection scope.
