The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 2 to 8, the metering and guiding device provided by the embodiment of the utility model is shown, which at least comprises a main body 1, a clamping block 2, a driving member 3, a backstop module 4 and a self-locking module 5. The main body 1 is provided with a sliding groove 11, a main line hole 12 and a branch line hole 13, the main line hole 12 is located in the track direction of the sliding groove 11, the branch line hole 13 is not intersected with the sliding groove 11 and the main line hole 12, the main body 1 is further provided with a notch 14 communicated with the main line hole 12 and a check hole 15 communicated with the sliding groove 11, the wire clamping block 2 is in sliding fit in the sliding groove 11, the driving part 3 is used for driving the wire clamping block 2 to move along the track direction of the sliding groove 11, the check module 4 comprises an elastic part 41 and a check part 42, the check part 42 is located outside the sliding groove 11 and is rotatably connected with the main body 1, the elastic part 41 is suitable for providing elastic force for the check part 42 towards the direction of the wire clamping block 2, the check part 42 penetrates through the check hole 15 to abut against the wire clamping block 2, and the self-locking module 5 is used for fixing branch lines in the branch line hole 13.

It should be noted that, in the above arrangement, the branch line hole 13 does not intersect with the chute 11, so as to avoid mutual interference between the clamping block 2 and the branch line when moving along the track direction of the chute 11, and the branch line hole 13 does not intersect with the main line hole 12, so as to avoid knotting between the main line 7 and the branch line when installing the main line and the branch line, thereby ensuring the reliability of the metering and guiding device when in use.

When the cable clamp is used, the main line hole 12 can penetrate through the notch 14 to enter the main line hole 12, then the driving piece 3 drives the cable clamping block 2 to move towards the main line hole 12 in the sliding groove 11, finally the main line 7 is tightly propped against the main line hole 12, then the branch lines can be penetrated into the branch line holes 13, and the branch lines are fixed in the branch line holes 13 in a loosening-proof manner through the self-locking module 5. Since the main line 7 generally has a larger diameter and a more complicated stress condition, the connection of the main line 7 by the wire clamping block 2 is unreliable, and the wire clamping block is easily loosened over time, and the non-return module 4 can reduce the possibility of loosening the wire clamping block 2. The method comprises the following specific steps: when the main line 7 is abutted against the main line hole 12 by the clamping block 2, the elastic member 41 provides the stopping member 42 with elastic force toward the direction of the clamping block 2, so that the stopping member 42 passes through the stopping hole 15 to abut against the clamping block 2, and the stopping member 42 is rotatably connected with the main body 1, so that the stopping member 42 does not slide along the sliding groove 11, and thus, once the stopping member 42 is abutted against the clamping block 2, the clamping block 2 cannot be easily loosened in the sliding groove 11 only by the force of the clamping block 2 along the sliding groove 11 unless the external force directly acts on the stopping member 42 and forces the stopping member 42 to rotate to separate from the clamping block 2, thereby ensuring the reliability of the connection of the metering and guiding device of the present invention with the main line 7.

As a preferred embodiment, referring to fig. 5 and 7-8, one surface of block 2 facing to check hole 15 is provided with first helical teeth 21, one surface of check 42 facing to block 2 is provided with second helical teeth 421, first helical teeth 21 are obliquely arranged away from main line hole 12, and second helical teeth 421 are obliquely opposite to first helical teeth 21. Through the arrangement mode, when the check block is matched with the thread clamping block 2, the thread clamping block 2 only can move towards the main thread hole 12, and the movement departing from the main thread hole 12 is completely locked, so that the reliability of connection with the main thread 7 is further ensured. The principle of the non-return of the first helical teeth 21 and the second helical teeth 421 is similar to that of a ratchet mechanism, and is not described herein again.

The possibility of the ratchets 42 moving along the track direction of the sliding grooves 11 is limited by the rotating shafts 43, and it is almost impossible that the force of the clamping blocks 2 along the track direction of the sliding grooves 11 tries to rotate the ratchets 42 against the elastic force of the torsion springs, so that the main wire 7 is not loosened in the main wire hole 12 in this way.

Preferably, referring to fig. 5 to 6, the main body 1 is provided at the outside thereof with two bar-shaped protrusions 17 protruding from the main body 1, and the check hole 15, the rotation shaft 43, the check 42, and the torsion spring are located between the two bar-shaped protrusions 17.
