Concave platform has been seted up in one side that grounding body 1 deviates from first wire winding support 2, makes through-hole 4111 and concave platform sliding fit to box 411 can only carry out directional motion on grounding body 1's concave platform, has played spacing effect, makes box 411 can closely overlap on locating grounding body 1, avoids cylindrical structure's grounding body 1 to appear rotating easily in the course of the work and influences the condition of working effect.
As shown in fig. 4, two opposite side walls of the box 411 are respectively provided with a fixing groove 4112 and a connecting hole 4113, the fixing groove 4112 and the connecting hole 4113 provide installation spaces for two ends of the unlocking sheet 412, the unlocking sheet 412 is respectively inserted into the fixing groove 4112 and the connecting hole 4113 and sleeved on the grounding body 1, and the unlocking sheet 412 is used for locking and unlocking the box 411. The elastic member 413 is specifically a compression spring, the elastic member 413 is disposed in the box 411 and sleeved on the grounding body 1, two ends of the elastic member 413 respectively abut against an inner wall of the box 411 and the unlocking sheet 412, and the elastic member 413 plays a role in elastic reset. Adopt this kind of structure, compare with prior art, second wire winding support 4's fixed effectual, avoid because of the circumstances that violent vibrations lead to second wire winding support 4 gliding, guarantee that grounding body 1 squeezes into going on smoothly of ground work, reduce external interference factor, user experience feels high.
Elastic component 413, unblock piece 412 overlap from top to bottom and set up in the holding intracavity of box 411 and the cover is located on the grounding body 1, under the recovery effort of compressed pressure spring, unblock piece 412 is fixed in fixed slot 4112 and is close to most advanced inner wall with connecting hole 4113 to spacing in the one end that is close to most advanced with box 411, it is great to accomodate the distance between frame 42 and the first wire winding support 2 this moment, the realization is being accomodate and is being made a round trip to establish the soft copper heart yearn of stranded between frame 42 and the first wire winding support 2. When stirring unlocking sheet 412 upwards, unlocking sheet 412 removes and compresses the pressure spring gradually to the direction that is close to the pressure spring, and when the part that unlocking sheet 412 is located box 411 was perpendicular with the axis of grounding body 1, unlocking sheet 412 did not with the inner wall of fixed slot 4112 and the inner wall looks butt of connecting hole 4113 for grounding body 1 upwards slides can be followed to box 411, thereby is accomodate the soft copper heart yearn of stranded and can once only with accomodate frame 42 and first winding support 2 and separate. When the unlocking sheet 412 stops being pulled, the compressed spring pushes the unlocking sheet 412 to reset under the self-recovery action force of the compressed spring.
Preferably, the fixing groove 4112 and the connecting hole 4113 are arranged opposite to each other, that is, a central connecting line between the fixing groove 4112 and the connecting hole 4113 is perpendicular to an axis of the grounding body 1, and a length of the connecting hole 4113 in an axial direction of the grounding body 1 is greater than a length of the fixing groove 4112 in the axial direction of the grounding body 1, so that under the pressing action of the elastic member 413, the unlocking tab 412 and the box 411 are arranged obliquely, at this time, an acting force of the elastic member 413 on the unlocking tab 412 can be decomposed into a first component force in the axial direction of the grounding body 1 and a second component force perpendicular to the axial direction of the grounding body 1, the first component force enables the unlocking tab 412 to be pressed against inner walls of the fixing groove 4112 and the connecting hole 4113.
Further, this multi-functional earthing pin still includes locating part 5, and locating part 5 specifically is spacing bolt, and locating part 5 wears to locate the grounding body 1 and is close to most advanced one end for spacing box 411. Under the action of the elastic member 413, an included angle exists between the unlocking sheet 412 and the grounding body 1, so that the box 411 is positioned on the limiting member 5.
