[0040] The working principle of the present application is that: when operating, first place the main wire harness in the C-shaped supporting plate in the supporting frame 9, then adjust the position of the multiple group assemblies 4 through the slide rail 2 and the sliding block 7, so that the sub-wire harness on the main wire harness can be fixed on the group assembly 4, then the operator's hand contacts the side end of the sliding block 44, applies a rotating force to the sliding block 44, the sliding block 44 rotates in the adjusting groove 42, the limiting block 48 in the side end mounting groove 45 rotates, the arc surface of the limiting block 48 contacts the edge of the limiting hole 43 on the inner side of the adjusting groove 42, a friction force is generated at the contact point, as the rotation continues, the limiting block 48 is subjected to a pushing force along the axis of the mounting groove 45, moves towards the inside of the mounting groove 45, the spring I 47 between the limiting block 48 and the connecting plate 46 is compressed, the length of the spring I 47 is shortened, the elastic potential energy is increased, when the limiting block 48 completely leaves the range of the limiting hole 43, the external pushing force on the limiting block 48 disappears, the spring I 47 releases the elastic potential energy, then pushes the limiting block 48 to move towards the outside of the mounting groove 45, returns to the initial position, at this time, the constraint between the sliding block 44 and the adjusting groove 42 is released, the operator can push the sliding block 44 along the extension direction of the adjusting groove 42, the convex structure at the bottom of the sliding block 44 matches the convex track of the adjusting groove 42, slides along the track direction until reaches the preset area corresponding to the sub-wire harness connected with the device, after reaching the target area, the operator applies a rotating force to the sliding block 44 again, the sliding block 44 continues to rotate, the arc surface of the limiting block 48 contacts the inner wall of the adjusting groove 42, the inner wall generates a radial pressure on the limiting block 48, forces the limiting block 48 to move towards the inside of the mounting groove 45 again, the spring I 47 is compressed again, the operator continues to rotate the sliding block 44, so that the two limiting blocks 48 and the two limiting holes 43 on the two sides inside the adjusting groove 42 are in the same vertical direction, which can be judged through the direction of the mounting plate 51, then continues to push the sliding block 44 to slide left and right in the adjusting groove 42, so that the position of the limiting block 48 is aligned with a group of limiting holes 43 on the inner side of the adjusting groove 42, the radial pressure on the limiting block 48 disappears, the spring I 47 pushes the limiting block 48 to move outward again, inserts into the inside of the limiting hole 43, the limiting block 48 is attached to the inner wall of the limiting hole 43, the sliding block 44 is fixed at the current position, the sub-wire harness connected with the device is concentratedly placed in the same area through this operation, which is convenient for distinguishing, and creates conditions for subsequent wire cutting, terminal crimping, branch arrangement, packaging, detection and other processes, when the terminal installation of one end of the sub-wire harness is completed, the operator holds the terminal end of the sub-wire harness, passes it through the gap between the clamping block one 57 and the clamping block two 510, after the terminal completely passes through the gap, the operator's hand contacts the outer side of the clamping block one 57, applies a pushing force along the direction of the moving groove 52, the moving block 53 at the bottom of the clamping block one 57 slides along the convex track of the moving groove 52 towards the direction where the clamping block two 510 is located, the clamping block 58 at one end of the clamping block one 57 moves with the clamping block one 57, the inclined surface thereof contacts the inclined surface of the clamping groove 511 at one end of the clamping block two 510,The contact force makes the clamping block one 57 move in the direction perpendicular to the moving groove 52 inside the cavity 55, the spring two 56 between the clamping block one 57 and the inner wall of the cavity 55 is stretched, the length of the spring two 56 increases, the elastic potential energy accumulates, the clamping block 58 slides along the inclined surface of the clamping groove 511, and after being completely separated from a group of clamping grooves 511, it enters the range of the next group of clamping grooves 511. At this time, the right angle short side of the clamping block 58 is in contact with the right angle short side of the clamping groove 511 to form a mechanical locking structure, and the clamping block one 57 cannot move in the opposite direction. The elastic potential energy of the spring two 56 remains stable, and the operator continues to push the clamping block one 57. The moving block 53 continuously slides in the moving groove 52, and the gap between the clamping block one 57 and the clamping block two 510 gradually narrows. When the width of the gap is greater than the diameter of the sub-wire harness and less than the width of the terminal, the operator stops applying the pushing force. At this time, the sub-wire harness is limited between the two clamping blocks, and the terminal is blocked outside the clamping block. The fixing is completed. After completing each process, the operator holds the side end of the synchronous ring 63 with his hand and applies an axial pushing force to push the synchronous ring 63 to move in the direction of the adjusting ring 41. The synchronous ring 63 drives the four groups of connecting ears two 62 to move, and the connecting ears two 62 drive the connecting rod 61 to slide along the axis of the connecting ear one 49. The plugboard 64 at one end of the synchronous ring 63 moves with the synchronous ring 63, and the separation plate 68 at the front end of the plugboard 64 gradually approaches the gap between the clamping block one 57 and the clamping block two 510. The separation plate 68 is inserted into the gap at an inclined angle, and the inclined surface thereof is in contact with the surface of the push plate 612. With the continuous movement of the synchronous ring 63, the separation plate 68 applies a pushing force to the push plate 612, and the push plate 612 drives the top rod 611 to move inside the cavity 55. The end of the top rod 611 is in contact with the clamping block one 57, and the clamping block one 57 is pushed to move inside the cavity 55. The spring two 56 is further stretched, and the contact pressure between the clamping block 58 and the clamping groove 511 decreases. When the clamping block one 57 moves to completely separate the clamping block 58 from the clamping groove 511, the locking structure is released. At this time, the push plate 612 is in abutment with the side end of the moving seat one 54. Then, the separation plate 68 continues to be inserted into the gap, and the inclined surface of the separation plate 68 transmits the pushing force through the push plate 612 to push the moving seat one 54 to move away from the clamping block two 510. The moving block 53 at the bottom of the moving seat one 54 slides along the moving groove 52, and the clamping block one 57 moves with the moving seat one 54. The gap between the clamping block one 57 and the clamping block two 510 gradually expands until the stop plate one 69 is in abutment with the moving seat two 59, the stop plate two 610 is in abutment with the push plate 612, and the separation plate 68 is completely inserted between the moving seat one 54 and the moving seat two 59. Then, the L-shaped clamping plate 67 is rotated to make the inner side thereof adhere to one side of the adjusting ring 41, so that the adjusting ring 41 and the synchronous ring 63 remain in the adhered state, and the open state of the clamping part 5 is maintained. At this time, all the sub-wire harnesses on the grouping assembly 4 are completely released from the constraint, and the operator can hold the terminal end or wire body part of the sub-wire harness to take it out from between the clamping blocks.The sub-wire harnesses connected with the device are centrally distributed in the same area, which provides convenience for subsequent processes such as wire cutting, terminal crimping, branch arrangement, bandaging, detection and the like, reduces the confusion or entanglement of the sub-wire harnesses due to disordered distribution, improves the smoothness of process connection, and realizes stable fixation of the sub-wire harnesses through cooperation of the clamping blocks of the clamping piece 5, combination of the inclined surface contact of the clamping block 58 and the clamping groove 511 and the right-angle short edge locking, prevents the sub-wire harnesses from loosening or falling off, adapts to the fixation requirements of sub-wire harnesses of different sizes through sliding of the moving block 53 in the moving groove 52 and elastic expansion of the spring 56, facilitates assembly and disassembly of the sub-wire harnesses, avoids damage to the sub-wire harnesses and prevents the terminals from falling off through precise control of the distance between the two clamping blocks, provides a stable operation basis for subsequent processes, releases the locking of all sub-wire harnesses at one time and expands the clamping distance through the release piece 6 pushing the synchronous ring 63 to drive multiple groups of separation plates 68 to be synchronously inserted between the clamping blocks, cooperates with the clamping plate 67 to fix the fit state of the synchronous ring 63 and the adjusting ring 41 to maintain the opening of the clamping piece 5, does not need to continuously apply force, releases the locking and expands the distance in succession through linkage of the jacking rod 611 and the push plate 612, reduces the operation steps, realizes synchronous release of multiple groups of sub-wire harnesses, improves the wire taking efficiency, and avoids the tediousness of releasing fixation one by one.
