In a typical structure, a mounting hole is formed in the thickness direction of the top plate 510, and the connection bridge 600 is fitted into the mounting hole.

In one embodiment, the connecting bridge 600 is non-detachably connected to one of the two auxiliary fixing cards 500, and the connecting bridge 600 is detachably connected to the other of the two auxiliary fixing cards 500.

The special split arrangement is convenient for a user to use, and three separate structures of the two auxiliary fixing clamps 500 and the connecting bridge 600 are not formed while flexibility is provided in the using process; but one auxiliary fixing clip 500 is formed as a separate structure with the connection bridge 600 and the other auxiliary fixing clip 500 is formed as a separate structure. For example, one auxiliary fixing clip 500 and the connecting bridge 600 are integrally formed, and the other auxiliary fixing clip 500 is separately formed and forms a snap-fit connection or an interference-fit connection with the free end of the connecting bridge 600.

In one embodiment, the connecting bridge 600 is detachably connected to the other of the two auxiliary fixing clips 500 in a snap-fit manner.

For example, a plurality of protruding ribs are arranged at the free end of the connecting bridge 600, inner grooves corresponding to the protruding ribs are arranged in the mounting holes on the top plate 510 of the independent auxiliary fixing clip 500, and the connecting bridge 600 and the auxiliary fixing clip 500 are clamped by the protruding ribs and the inner grooves in a matching manner.

Referring to fig. 3, in one embodiment, a second position-limiting groove 610 is formed on a side of the connecting bridge 600 facing the U-shaped buckle 100, and the second position-limiting groove 610 includes a portion matching with the shape of the top of the U-shaped buckle 100.

The direction of the first position-limiting groove 530 is parallel to the outer steel wire 700, but in this embodiment, the auxiliary fixing clip 500 has the first position-limiting groove 530; the connecting bridge 600 is further provided with a second limiting groove 610, and the second limiting groove 610 is matched with the top of the U-shaped buckle 100 in shape, and the second limiting groove 610 is perpendicular to the external steel wire 700, so that the stability of the integral structure formed by the two auxiliary fixing clips 500 and the connecting bridge 600 is high.

Referring to fig. 1 to 4, in one embodiment, a protrusion 521 is disposed on an inner side of a free end of the fixing leg 520, the latch slot 220 has a plurality of catching grooves 221 respectively formed on outer walls of both sides in a width direction and distributed in a height direction of the latch 200, and the catching grooves 221 are used for matching and fixing the protrusion 521.

In this embodiment, the fastening groove 221 is used to form a detachable fixed fit with the free end of the fixing leg 520, so that the degree of the auxiliary fixing clip 500 to be combined with the slot 220 can be adjusted by combining the fixing leg 520 with the fastening grooves 221 of different heights, and the fixing pressure provided by the auxiliary fixing clip 500 can be adjusted accordingly.

Referring to fig. 1-4, in one embodiment, the catching groove 221 is inclined upward toward the U-shaped buckle 100 as a whole, and the protrusion 521 is formed in a barb shape to correspond to the catching groove 221.

The inclined trend of the catching groove 221 and the inverted hook shape of the protrusion 521 make the fixing leg 520 not easy to be separated from the card slot 220, thereby ensuring the fixing effect; while not preventing the fixed leg 520 from exiting the current capture slot 221 to engage the next capture slot 221.

In one embodiment, the dimension of the fixing leg 520 in the thickness direction of the U-shaped buckle 100 is one half of the dimension of the card slot 220 in the thickness direction of the U-shaped buckle 100.

The thickness limitation of the fixing legs 520 ensures the stability of the combination of the auxiliary fixing clip 500 and the clip slot 220, and facilitates the fixing legs 520 to be released from the clip slot 220 from the length direction of the outer steel wire 700.

To sum up, the utility model provides a copper wire checkpost can be fixed with the restriction of outside copper wire 700 to a certain extent through first spacing groove 530, also can make supplementary fixing clip 500 fixed comparatively firm simultaneously. During the process of installing the auxiliary fixing clip 500, the auxiliary fixing clip 500 thus completes the process of fixing the keeper 200 in place, facilitating the fastening of the washer 400 and the nut 300 to the screw structure 110 of the clevis 100.

The above only is the preferred embodiment of the present invention, and the patent scope of the present invention is not limited thereby, and all the equivalent structures or equivalent processes made by the contents of the specification and the drawings are utilized, or directly or indirectly applied to other related technical fields, and all the same principles are included in the patent protection scope of the present invention.
