Low cost and other advantages.
The utility model solves above-mentioned technical problem with following technical scheme：
Being provided with the utility model transmission line of electricity cabling special sheath, including grip body, grip body is available for wire to slide
Enter the roller that can be walked along wire is installed in the breach of grip body inner chamber, grip body and the brake system of wire can be vised
Dynamic device.
The braking device includes brake block group, lifting arm, brake lever, and brake block group is by symmetrical brake block structure
Into, the top of brake block and one end of lifting arm are hinged, the other end of lifting arm stretch out grip body it is outer and with brake lever
One end is hinged, the front portion of brake lever and the support seat hinge being fixed in grip body, and return spring is cased with simultaneously on lifting arm
In spring housing.
The rear portion of the brake lever is provided with the fixation kit of brake lever, and the fixation kit includes brake bar, return
Return spring is cased with spring, spring housing and pin cap, brake bar and in spring housing, and pin cap is fixed on brake bar
Rear end and the outboard end for being stuck in spring housing, the front end of brake bar can withhold the rear portion of brake lever.
The roller is provided with two, and each roller is arranged on roller shaft by bearing, and roller shaft is fixed on gripping master
On body.
The grip body, provided with sealing pin bank, is skidded off in indentation, there for limiting wire.
Using the utility model transmission line of electricity cabling special sheath, the efficiency and security during walking wire can be lifted, together
When can reduce the abrasion to wire, and with it is light carry, easy-to-use wear-resisting, low cost and other advantages.
