The annular connecting piece 9 and the lifting cylinder 59 are made of insulating materials.

The working principle is as follows: when the device is used, the device is placed in a working area, then the fracture of two cables to be connected is peeled, internal copper wires are exposed, then the cables can be connected through the device, when a cable is connected with the annular connecting piece 9, the cable is directly inserted into the rubber pipe 12 along the rubber protective sleeve 11, then the cable is extended inwards until the copper wires are contacted with the conductive rod 13 to form a passage, so that the cable is connected, the operation is simple and convenient, the cable is arranged in an arc shape, in addition, the elastic clamping of the rubber pipe 12 is realized, the cable cannot be easily loosened before secondary clamping is not carried out, after the cable is connected, the cable is installed, the installation ring 29 is firstly pulled out, in the pulling-out process, an operator needs to pull out the plurality of plug blocks 25 in advance, and the installation ring 29 is lack of limit, can be smoothly pulled out, then nuts on the two locking rods 47 are rotated to enable the locking rods 47 to slide with the cable clamping ring 48, then the cable clamping ring 48 is pulled forcefully, so that the whole can be pulled out, after the whole is pulled out, the cable passes through the cable clamping ring 48 and the lifting ring 46, then the cable is wound on the plurality of movable rods 41 in a spiral manner, a cable groove 60 is further formed in each movable rod 41 to facilitate the winding of the cable, after the winding is finished, one end of the second cable extends into the locking block 35, so that copper wires of the second cable are in contact with the second conducting strip 38 to form a passage, and then the whole is inserted, so that the device can be normally used, in the process of re-installation, because the inserting block 25 is in sliding connection with the inserting hole 26, and the inserting block 25 is provided with the second return spring 21 and the movable groove 37, and a lateral wall of the plug-in block 25 is inclined, so that the insertion of the mounting ring 29 can be facilitated, and after the mounting is finished, the nut at the bottom end of the locking rod 47 is locked again to limit the position again, so that the device can be used normally.

During the use, according to the mode that figure 2 shows and rotate certain distance to the left, will make third conducting strip 78 stretch into logical groove 7 like this to make third conducting strip 78 and first conducting strip 5 and second conducting strip 38 form the route, can electrically conduct, guarantee the normal work of cable, still be provided with first stopper 30 and spacing groove 8 on the outer wall of binding post 1 simultaneously, can press from both sides tightly the cable in the pivoted in-process to annular connecting piece 9 like this, its clamping process is: after first stopper 30 is touched to kicking block 23, can make clamping bar 19 remove, thereby make arc clamping block 22 press from both sides tight rubber tube 12 department, conducting rod 13 and conductive spring section of thick bamboo 14 then can make the copper line of a cable rather than circular telegram, and slide bar 15 in the conductive spring section of thick bamboo 14, sliding block 16 and first reset spring 17's setting, make the third conducting strip 78 can be fine stretch into logical inslot 7, and the setting of spacing groove 8, then be fine can adapt to kicking block 23, make can be stable block in inside, thereby keep pressing from both sides tight stability.

When the cable is pulled by the operator due to the work, since the second cable is wound in the cable groove 60 of the plurality of movable bars 41, and a cable is fixed in the annular connecting piece 9, the annular connecting piece 9 is sleeved on the wiring piece 1, thus during the dragging process, since the connection of the first cable is in lateral contact with the junction element 1, the pulling force is longitudinal, this avoids the problem of separation looseness between the first conductive sheet 5 and the second conductive sheet 38, thereby avoiding the problem of open circuit, and simultaneously, the dragging of the second cable can make the plurality of movable rods 41 gather to the middle, during the gathering process, the cable clamp ring 48, which is also slidable, is provided with a first hinge rod 43, a clamping plate 44, a second hinge rod 45, a lifting ring 46 and a locking rod 47, such that when the cable clamp ring 48 is moved, the clamp plates 44 within each clamp groove 42 are caused to begin to move, thus converging toward the middle, so as to clamp the cable, and at the same time, a triangular support frame 65, a fixed sleeve 66, an L-shaped top rod 67, an insulating rod 68, a hinge groove 69, a rotary sleeve 70, a third hinge rod 71, a fourth dovetail groove 72, a fourth dovetail block 73, a hinge cylinder 74, a stabilizing sleeve 75 and a stabilizing rod 76 are arranged in the lifting cylinder 59, when the cable clamping ring 48 descends, the insulating rod 68 is lowered, and when the insulating rod 68 is lowered, the angle of the third hinge rod 71 is shifted, thereby pushing the L-shaped push rod 67 upwards, so that the pressing plate 77 is lifted, thereby pressing the contact position of the second cable copper wire and the second conductive sheet 38, avoiding the looseness, therefore, when the operator drags, the operator can have a certain dragging space, the connection stability can be ensured, and the occurrence of short circuit or poor contact is avoided.

Be provided with apron 4, make things convenient for the dismantlement and the installation of first conducting strip 5, be provided with rubber protective sheath 11, protect No. one cable, avoid appearing damaging, be provided with fixed plate 18, compression bar 19, dog 20, second reset spring 21, arc compact heap 22 and kicking block 23, guarantee the normal clear of No. one cable pressing operation, be provided with cavity 31, spring 32, first spacing slider 33, first spacing slide bar 34, latch segment 35 and spacing hole 36, make No. two cables accomplish the installation back, can make the fine card of latch segment 35 with in inside, be provided with second dovetail 50, second dovetail 51, second spacing block 52, ring channel 53, sealing ring 54, connecting rod 55, third dovetail 56 and third dovetail 57, guarantee the even running of device, can be dragged certain distance.

The device passes through wiring spare 1 and annular connecting piece 9's cross connection mode for the pulling between a cable and the No. two cables can not influence the contact between first conducting strip 5 and the second conducting strip 38, the condition of avoiding appearing breaking takes place, be provided with other spare parts in wiring spare 1 simultaneously, make the fixed more firm of No. two cables, at the in-process of dragging, can have certain activity space, avoid appearing the condition of contact failure again and take place, easy operation is convenient, the security of device has been improved, the availability factor of device has been improved to a certain extent.
