Description

Fixing-line device

Technical field

The utility model relates to a kind of electric power stringing device, and what be specifically related to is a kind of unwrapping wire of lead and fixing-line device of stringing of being used for.

Background technology

Fixing-line device is a kind of power tool that uses when unwrapping wire and stringing in the power supply department stringing process.Traditional fixing-line device comprises mainboard, connecting plate, torque arm and draw ring, lower jaw is fixed on the position, lower edge of mainboard left end, center, upper jaw back by bearing pin be hinged on win in succession on, upper and lower jaw position correspondence, the two ends of winning in succession are hinged with the left end of the left end of mainboard and torque arm respectively, the right-hand member of torque arm and the front end of draw ring are hinged on jointly by a bearing pin in the horizontal groove of mainboard right-hand member, and the type of attachment between the horizontal groove of mainboard, connecting plate, torque arm and mainboard right-hand member makes fixing-line device form a kind of four-bar linkage structure main body.The defective that this fixing-line device exists is: 1. when jaw opened, upper jaw always rotated around its jointed shaft at random, makes that the bead of bit is not parallel, and lead is not easy to put into jaw; 2. lead is put into after the jaw, and jaw can not be clamped lead automatically, must strain draw ring, otherwise lead comes off from jaw easily always.These two kinds of defectives all make troubles to work high above the ground.

Summary of the invention

The purpose of this utility model is to overcome the existing above-mentioned defective of traditional fixing-line device, provides a kind of easy to use, simple to operate, the fixing-line device easily of card line.

The technical scheme that realizes above-mentioned purpose is: a kind of fixing-line device, the horizontal groove that comprises mainboard, connecting plate, torque arm and mainboard the right of forming fixing-line device four-bar linkage structure main body, also comprise a draw ring and be positioned at the lower jaw on the mainboard and be positioned at upper jaw on winning in succession, upper and lower jaw position correspondence, draw ring one end and torque arm right-hand member head are hinged, its jointed shaft is arranged in the horizontal groove of mainboard, it is characterized in that: there is one section circular arc groove in described mainboard stage casing; The back of described upper jaw take back the position be hinged on win in succession on, the right-hand member head of upper jaw is connected to by a bearing pin in the circular arc groove of described mainboard, this bearing pin can slide in the circular arc groove; The direction of described circular arc groove should guarantee upper jaw with radian, and aprowl its bead is parallel with the bead of lower jaw all the time; Described torque arm is provided with a spring support, is equipped with one on this spring support and makes the automatically reset spring of fixing-line device energy.

The bead of the utility model fixing-line device bit is all keeping state parallel to each other always under any state, during the card line, only need touch draw ring, bit opens with regard to parallel, and lead is easy to put into jaw, after lead is put into jaw, under the effect of back-moving spring, jaw is clamped lead automatically, and produces certain pretightning force, and lead can not come off.This fixing-line device simple structure, rationally, operation easily, convenient, make that work high above the ground is quick more, safety.
