Further, the hinge is a pin.

Further, the elastic member is a torsion spring.

Further, the inner walls of the two shells are provided with clamping blocks, and the inner side walls of the two clamping blocks are provided with grooves.

Further, the outer side arms of the two shells are provided with anti-slip ribs.

The beneficial effects of the utility model include:

1. when the two shells are pinched by hands, the lead is clamped into the through hole formed by the grooves on the inner side walls of the two shells, the lead can be pulled by pulling the two shells by hands, after the hands are loosened, the two shells can be opened under the action of the elastic force of the elastic piece, so that the lead is loosened, the next bracing couple work can be conveniently carried out, bracing is convenient, the lead can be prevented from being damaged, and meanwhile, the bracing efficiency is high;

2. the outer side arms of the two shells are provided with anti-slip ribs, and the anti-slip ribs can prevent hands from slipping when the two shells are pulled by hands, so that the two shells can be pulled more conveniently.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1-4, the utility model provides a manual wire pulling device, which comprises two shells 1, wherein the two shells 1 are arc-shaped shells, one sides of the two shells 1 are hinged through a hinge piece 2, an elastic piece 3 for automatically opening the two shells 1 is arranged between the two shells 1, and grooves 111 are formed in the inner side walls of the two shells 1; when the two housings 1 are closed, the grooves 111 on the inner side walls of the two housings 1 form a through hole which is matched with the concave-convex positions on the lead 4.

When holding two shells 1 with the hand, in the through-hole that two shells 1 inside wall recess 111 formed will be blocked into to lead 4, the pulling of hand is two shells 1 can be with lead 4 pulling, after unclamping the hand, can make two shells 1 open under the elasticity effect of elastic component 3 to loosen lead 4, in order to conveniently carry out the even work of acting as go-between next, it is convenient to act as go-between, can avoid the lead fragile, and it is efficient to act as go-between simultaneously.

The lead 4 includes a lead body 41 and annular protrusions 42 provided at equal intervals on the lead body 41 to form concave-convex positions on the lead 4, and a wire hanging buckle 43 for connecting wires and cables is provided at one end of the lead 4.

It should be noted that, the groove 111 includes a first arc groove provided on the inner sidewall of the housing 1 and engaged with the lead body 41, and a second arc groove provided on the inner sidewall of the first arc groove at equal distance and engaged with the annular protrusion 42.

In this embodiment, the hinge 2 is a pin.

It is only necessary for the hinge 2 to be able to hinge one side of the two housings 1, and thus it is not limited to the form of a pin, for example, in other embodiments, the hinge 2 employs a rivet or a hinge or the like to hinge the hinge 2 to be able to hinge one side of the two housings 1.
