Description

Tear the guide head open

Technical field

The utility model relates to a kind of extracting tool, relates in particular to a kind of guide head of tearing open.

Background technology

When tearing the support swivel pin open habitually in the past, employed silk head be chain link with transporter after front end processes gap, the stud weld of use respective diameters connects; Chain link becomes as a whole with bolt, because the present support specification of removing of returning is bigger, the bearing pin of being torn open is very thick; Bolt on the silk head is after receiving very big pulling force, and the silk of bolt is easy to damage, and the silk head had just lost efficacy accordingly; Reusable number of times seldom, therefore, each working face returns to remove all needs a large amount of heads; The chain link quantity of using is bigger, does not meet the requirement of the energy-saving and emission-reduction of present proposition, causes very big waste.

Summary of the invention

The purpose of the utility model provides and a kind ofly is repeatedly used, result of use is good tears the guide head open.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of guide head of tearing open comprises handle; It is characterized in that: said handle is the U-shaped handle; The two ends of handle are fixedly connected with holder respectively, and the activity of being designed with between the holder is pullover, and activity is pullover to be rotatably connected with holder relatively.

In this structure, the movable pullover pullover body that comprises, pullover body two ends are designed with connecting axle, and connecting axle is positioned at holder.

The utility model has the advantages of and be: because the utility model handle is the U-shaped handle, the two ends of handle are fixedly connected with holder respectively, are designed with movable pullover between the holder; Activity is pullover to be rotatably connected with holder relatively; So when using the utility model demounting bolt, convenient and swift, save material; Can be repeatedly used, result of use is good.
