[0014] Furthermore, the insulating outer rod and the insulating inner rod are both hollow tubes, and a through hole communicating with the insulating inner rod is provided at the bottom of the fastening sleeve.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention adopts an insulating rod with an inner and outer double-rod coaxial nested design to clamp the J-type wire clamp and the main conductor, connect the lead wire and cooperate with the lead fixing rod and the traditional gun rod locking mechanism and unlocking rope to achieve locking and unlocking at the same rod head of the insulating rod, complete the clamping operation of the docking lead wire, realize single-person operation of live working, save labor costs, and improve work efficiency.

[0017] 2. The clamping slot of the present invention includes a limit frame and an upper edge of the wire clamping slot connected in a C-shaped structure by adjusting bolts, so that the extension distance of the upper edge of the wire clamping slot can be adjusted according to the model of the J-type wire clamp, thereby adapting to different models of J-type wire clamps, thereby increasing the versatility of the tool. The limit frame can prevent the two-lobed clamping slot of the J-type wire clamp from being misaligned.

[0018] 3. The insulating outer rod of the present invention is sleeved on the insulating inner rod, and a tightening sleeve is arranged on the top of the insulating inner rod.

[0021] 6. The other end of the second fixing rod of the present invention is hinged to the locking mechanism sleeved on the insulating outer rod. When the locking mechanism moves up and down on the insulating outer rod, it can drive the second fixing rod to move up and down, thereby realizing the rotation of the first fixing rod on the limit frame.

[0022] 7. The locking mechanism of the present invention is a locking mechanism commonly used in shooting gun rods, and its unlocking device is connected to one end of a pull rope, and the other end of the pull rope is arranged at the hinge of the first fixed rod and the second fixed rod, so that personnel can easily achieve the locking and unlocking operation of the locking mechanism on the insulating outer rod by pulling the pull rope.

[0023] 8. An electric wrench interface and a limit ring are provided at the bottom of the insulating inner rod of the present invention. The limit ring limits the relative activity area of ​​the insulating inner and outer rods to prevent the inner and outer rods from separating. The electric wrench interface facilitates rotating the insulating inner rod through an electric wrench to tighten the wire clamp. Description of the drawings:

[0029] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0030] The insulating rod includes a lead fixing rod and an insulating outer rod 12 and an insulating inner rod 10 nested with each other. The slot includes a limit frame 8 and an upper edge 2 of the wire clamp slot connected in a C-shaped structure by an adjusting bolt 1. The limit frame 8 is fixedly arranged on the top of the insulating outer rod 12. A fastening sleeve 7 is arranged on the top of the insulating inner rod 10. The fastening sleeve 7 follows the insulating inner rod 10 to penetrate the insulating outer rod 12 and extend into the slot. A spring 9 is sleeved on the insulating inner rod 10 between the fastening sleeve 7 and the insulating outer rod 12. The lead fixing rod is hinged on the limit frame 8, one end of which extends upward into the slot, and the other end of which is arranged on the insulating outer rod 12 through a locking mechanism 13.

[0031] The lead fixing rod includes a first fixing rod 61 and a second fixing rod 6. The first fixing rod 61 is hinged on the limiting frame 8. One end of the first fixing rod 61 is in an arc-shaped structure and extends into the card slot. The other end of the first fixing rod 6 is hinged to one end of the second fixing rod 6. The other end of the second fixing rod 6 is hinged to the locking mechanism 13 mounted on the insulating outer rod 12.

[0032] The hinged joint of the first fixing rod 61 and the second fixing rod 6 is fixed to one end of the pull rope 11 , and the other end of the pull rope 11 is fixed to the locking mechanism 13 .

[0033] The bottom of the insulating inner rod 10 extends out of the bottom of the insulating outer rod 12 , and a limiting ring 14 is provided on the extended end of the insulating inner rod 10 .

[0034] The bottom of the insulating inner rod 10 is provided with an electric wrench interface 15. The insulating outer rod 12 and the insulating inner rod 10 are both hollow tubes, and the bottom of the fastening sleeve 7 is provided with a through hole communicating with the insulating inner rod 10.

[0035] When in use, the process of connecting the wire (installing the wire clamp) is as follows:

[0036] The operator holds the upper end of the tool and adjusts the adjustment bolt 1 according to the J-type wire clamp model to make the clamp slot fit the current wire clamp. By pressing down the limit frame 8, lifting the pull rope 11 and the second fixed rod 6, a space for placing the wire clamp is reserved. Then the wire clamp 3 and the lead wire 5 to be connected are clamped into the clamp slot. Then the second fixed rod 6 is pressed down to clamp the lead wire 5 to be connected on the upper part of the first fixed rod 61. This process can be repeatedly debugged by operating the second fixed rod 6 and the pull rope 11. After the wire clamp 3 and the lead wire 5 to be connected are clamped, the insulating outer rod 12 is lifted up, the lower end of the insulating outer rod 12 is held in a suitable position, the wire 4 is clamped into the groove of the wire clamp 3, the insulating inner rod 10 is pushed up, the insulating inner rod is rotated, and the bolts in the wire clamp 3 are tightened, thereby tightening the wire clamp 3. Then, the locking mechanism 13 is operated to unlock, the wire clamp 3 and the lead wire 5 to be connected are released, and the insulating inner rod 10 is pulled down to flow out of the reserved space, so that the wire clamp 3 and the clamp slot are separated.

[0037] The process of connecting (removing the wire clamp) is the opposite of the installation process.

[0038] The operation steps of unlocking the rope are as follows: when the construction personnel clamp the wire clamp 3 and the lead wire 5 to be connected, in order to facilitate debugging, they can lock the clamp 3 and the lead wire 5 to be connected at the upper end of the insulating rod, or they can unlock and release the wire clamp 3 and the lead wire 5 to be connected at the upper end of the insulating rod. The specific operation is as follows: when locking, press down the second fixing rod 6, and drive the locking mechanism 13 to lock through the insulating outer rod 12 (the locking mechanism 13 is the locking mechanism used by the common shooting gun rod), so as to fix the wire clamp 3 and the lead wire 5 to be connected; when unlocking, pull up the insulating rope (pull rope 11) to trigger the unlocking device of the locking mechanism 13, and release the wire clamp 3 and the lead wire 5 to be connected.
