Description

Quick positioning expander

The invention relates to a pipe expander, in particular to a pipe expander which can be quickly positioned.

In general, the brake line of the vehicle is usually configured with a bushing for the brake wire to be worn, so that the brake wire is pulled or released by the brake trigger to be restrained in the inner space of the sleeve. Maintain its normal brake function and safety. The bushings for the brake wires may be adapted to the vehicle type and size difference, as well as the front and rear wheel brake configurations. Therefore, the required brake wires and the length of the bushings are often properly cut, however, for braking. Because of the multi-purpose hollow tubular design, the threaded sleeve is cut during the shearing process of the cutting pliers, because the two cutting edges of the cutting pliers will be clamped and then cut, so that the cutting end face will be The flattened type is presented, and even the subsequent brake line insertion operation is affected. Therefore, the slit end of the sleeve needs to be expanded by the expander to facilitate the subsequent brake line insertion operation.

According to the national patent I526259 is a tube expansion processing device with a view hole, comprising: a pair of molds, an upper mold half, a lower mold half and a plurality of fixed components; the upper mold half has a plurality of upper half lock holes and a The upper half of the hole has a plurality of lower half-locking holes and a lower half-hole.
