[Problems to be solved by the device]

 In the attachment of the automatic fixing device to the cable drum 1, it is necessary that the cylinder axis direction of the cylinder is oriented in the direction in which the cable winding start end a ′ drawn out from the outlet 2 on the side surface of the cable drum collar 1a. If there is not, it is not possible to smoothly insert the cable winding start end a ′ into the cylindrical body.

However, in the conventional automatic fixing device described in the above-mentioned publication, the inclination (direction) of the cylinder cannot be adjusted in the state of being fixed to the collar 1a. That is, normally, the fixing device is fixed to the rib (collar) of the body, but the amount of protrusion of the rib is small, and it is difficult to fix the cylindrical body in an arbitrary direction (see the above-mentioned publication and examples).

Further, if the size (diameter) of the cable drum is different, the lead-out direction of the cable winding start end a ′ also differs, so that it is necessary to align the tubular body in the lead-out direction for each drum of different size. However, due to the small amount of protrusion of the rib and the difference in curvature of the rib, it is very difficult to deal with this.

For this reason, when the conventional automatic fixing device is attached, the direction in which the cable winding start end a ′ is led out does not match the direction of the tubular body, and the end may not be smoothly inserted into the tubular body. there were.

According to the present invention, if the orientation of the tubular body can be adjusted even after being attached to the collar, the tubular body can be guided to the outlet without being affected by the small amount of protrusion and the difference in rib curvature. Focusing on the correspondence, the challenge is to be able to adjust the orientation of the cylinder.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, when the cable winding start end is inserted into the above-mentioned tubular body, the insertion causes the claw to bite into the cable end for chucking, and the cable described in the above publication is disclosed. In the winding start end fixing device, a connecting support metal is provided on the fixing metal fixture fixed to the flange of the cable drum so as to be vertically swingable and fixable, and the supporting metal fixed to the cylinder body is attached to the connecting support metal fixture. The metal tool is configured to be swingable in the front-back direction and fixed.
