As shown in fig. 8 to 12, the branch clamping mechanism includes two branch clamping arms 3 respectively hinged to two sides of the main body 1, and two adjusting components 4 respectively for driving the two branch clamping arms 3 to rotate. The branch clamping arm 3 can be rotated back and forth by adjusting the corresponding adjusting component 4, so that the branch clamping arm 3 has a branch clamping position for clamping the branch conductor 100 and a branch insertion position rotated away from the branch clamping position.

The two branch clamping arms 3 are in clamping fit with the top cover 2 to clamp and fix the branch wires 100, specifically, after the J-shaped wire clamp is placed on the main body 1, the top cover 2 is covered and locked, the top cover 2 supports against the J-shaped wire clamp from the outer side of the J-shaped wire clamp, then the branch wires 100 are inserted into wire grooves of J elements adjacent to the top cover 2, the branch clamping arms 3 are rotated to branch clamping positions by adjusting the adjusting assemblies 4, and the branch clamping arms 3 clamp the branch wires 100 from the inner side of the J-shaped wire clamp.

Specifically, referring to fig. 8 to 12 in combination, the adjusting head 42 is cylindrical, the connecting portion 31 is hollow cylindrical with a circular inner hole, the cylindrical adjusting head 42 is located in the circular inner hole of the connecting portion 31, and a gap is formed between the adjusting head 42 and the connecting portion 31, so that the adjusting head 42 and the connecting portion 31 can rotate relatively.

The adjusting head is in threaded connection with the adjusting bolt, the adjusting head abuts against the connecting portion on the branch clamping arm and then drives the branch clamping arm to rotate so as to clamp the branch wire, the branch clamping arm cannot loosen due to the fact that the branch wire is pulled after the branch wire is clamped, the branch clamping arm can bear the pulling of the branch wire in the upward lifting process of the wiring device, and therefore even if the wiring device is too fast in the upward lifting process of connecting the main guide wire or too large in force, the situation that the branch wire is separated from the J-shaped wire clamp cannot occur, and the wire can be ensured to be smoothly connected.

The two branch clamping arms are independently and asynchronously clamped, so that the two branch clamping arms can clamp the branch regardless of the peeling length of the clamping part on the branch, and the reliability of clamping the branch is improved.

According to the invention, the branch clamping arm is driven to clamp the branch lead by screwing the adjusting bolt, so that the branch clamp has the advantage of wide adjusting range and can be suitable for branch leads with more specifications.

In addition, the branch clamping mechanism also has the characteristics of simple structure, convenience in operation and small occupied space.

In an embodiment, the limiting stopper 44 includes a nut and a washer, wherein the washer is sleeved on the adjusting bolt 41, the nut is screwed on the adjusting bolt 41, the washer is located between the nut and the limiting plate 43, the nut and the washer are arranged close to one side of the limiting plate 43 adjacent to the branch clamping arm 3, and a gap is formed between the washer and the limiting plate 43 to ensure that the adjusting bolt 41 can rotate.

Further, as shown in fig. 8 to 11, the bolt heads of the two adjusting bolts 41 in the present invention are each provided with a star handle 45 for turning the adjusting bolt 41.

In an embodiment, as shown in fig. 8 to 12, the limiting plate 43 of the two adjusting assemblies 4 is a plate body, which is fixed to the main body 1 by screws, and the plate body is provided with two second kidney-shaped holes 431.

The main body 1 is provided with two opposite vertical arms 11, and the two vertical arms 11 are provided with mounting holes for mounting a wire clamp supporting structure.

As shown in fig. 13 to 17, the wire clamp supporting structure includes two movable suspension arms 51 and two return springs 52 respectively used for returning the two suspension arms 51, one end of each return spring 52 is fixedly connected to the suspension arm 51, and the other end is fixedly connected to the vertical support arm 11.

The two suspension arms 51 are correspondingly hinged in the mounting holes of the two vertical support arms 11, the suspension arms 51 are in an "L" shape, the suspension arms 51 are in an integrated structure, the suspension arms 51 comprise a vertical connecting portion 511 hinged with the vertical support arms 11 and a transverse suspension portion 512 positioned at the upper end of the vertical connecting portion 511, and the transverse suspension portion 512 has an initial position (at the moment, the return spring 52 is in a normal state) extending out of the vertical support arms 11 for suspending a J-shaped wire clamp and a retracted position (at the moment, the return spring 52 is in a compressed state) retracting into the vertical support arms 11.

The end of the transverse suspension portion 512, which is far away from the vertical connection portion 511, is pointed, and the support surface 5121 of the transverse suspension portion 512, which is used for suspending and supporting the J-shaped wire clamp, is a convex arc surface, so that the transverse suspension portion 512 retracts transversely when retracting, and the front section of the suspension support point of the transverse suspension portion 512 does not exceed the height of the suspension support point when retracting, and further, when the J-shaped wire clamp is tightened, the transverse suspension portion 512 can retract into the vertical support arm 11 easily.

Specifically, the center of curvature of the supporting surface 5121 is the hinge point between the vertical connecting portion 511 and the vertical arm 11. In this way, the trajectory line of the rotation of the support surface 5121 around the hinge point coincides with the curved surface of the support surface 5121 itself, and the design is ingenious, so that the front section of the suspension support point of the lateral suspension portion 512 can not exceed the height of the suspension support point when retracting. The front section of the suspension support point of the lateral suspension portion 512 refers to a section between one end of the lateral suspension portion 512 away from the vertical connection portion 511 and the suspension support point.

As shown in fig. 15 to 17, the lower portion of the vertical connection portion 511 is hinged to the vertical arm 11. The lower part of the vertical connecting part 511 is hinged with the vertical support arm 11, so that the rotation amplitude (angle) of the vertical connecting part 511 can ensure that the transverse hanging part 512 retracts into the vertical support arm 11 in a small range, and the transverse occupied space of the vertical connecting part 511 is saved.

Referring to fig. 13 to 17, the vertical arm 11 has a stop portion 111. The blocking portion 111 blocks the horizontal hanging portion 512 from moving from the initial position to the inner side of the vertical arm 11 by blocking the vertical connecting portion 511. The design of the resisting part 111 can prevent the J-shaped wire clamp from falling off from the transverse hanging part 512, can also avoid damaging the elastic performance of the return spring 52 due to misoperation, and is beneficial to ensuring the use effect of the wire clamp supporting structure.

The lower surface 5122 of the pointed end of the transverse hanging portion 512 opposite to the supporting surface 5121 is a cambered surface or an inclined surface. When the J-shaped wire clamp is tightened, a J element located below the J-shaped wire clamp abuts against the lower surface 5122 in the upward moving process so as to enable the transverse hanging portion 512 to retract, and the lower surface 5122 is provided with an arc surface or an inclined surface so that the J element abuts against the lower surface 5122 in a sliding mode, so that the transverse hanging portion 512 can retract conveniently.

In one embodiment, as shown in fig. 15 to 17, the lower surface 5122 is a cambered surface.

In order to ensure the suspension support performance of the suspension arm 51 and ensure that the transverse suspension portion 512 does not retract when the J-clamp is suspended, the return spring 52 is connected to the upper portion of the suspension arm 51, as can be seen in particular from fig. 15 to 17.

Further, as shown by referring to fig. 13 to 17, a spring mounting seat 112 is fixedly connected to an outer side plate surface of the vertical support arm 11 through a screw, a spring mounting hole 1121 is formed in the spring mounting seat 112, a spring connecting hole 513 is formed in the suspension arm 51, two ends of the return spring 52 are respectively located in the spring mounting hole 1121 and the spring connecting hole 513, and two ends of the return spring 52 are respectively fixedly connected to the suspension arm 51 and the spring mounting seat 112. The arrangement of the spring mounting hole 1121 and the spring connecting hole 513 rationalizes the mounting space of the return spring 52, and can reduce the lateral thickness dimension of the vertical arm 11.

When the transverse suspension part 512 retracts, the return spring 52 slightly twists, and in order to allow and realize the situation, the aperture of the spring mounting hole 1121 and the spring connecting hole 513 is 0.5-1 mm larger than the spring outer diameter of the return spring 52.
