It is desirable to improve efficiency and safety factors through improved techniques.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem mentioned in the background art, providing a shield constructs quick-witted tool changing safety crowbar.
In order to solve the technical problem, the utility model provides a technical scheme does: a shield machine tool changing safety crowbar comprises a stress rod and an extension rod, wherein a U-shaped connecting piece is fixedly arranged at the bottom of the stress rod and comprises two connecting rods, two first crowbars are fixedly arranged at the bottoms of the connecting rods, an expansion end is fixedly arranged at the top of the stress rod, and an installation groove is formed in the top of the expansion end;
the bottom of the extension rod is fixedly provided with an installation bulge matched with the installation groove, the top of the extension rod is fixedly provided with an arc prying handle, and the end part of the arc prying handle far away from the extension rod is fixedly provided with a second prying head.
Preferably, the two first prying heads are both perpendicular to the plane of the U-shaped connecting piece and located on the same side of the two connecting rods.
Preferably, the cross section of the mounting groove and the mounting protrusion is one of an equilateral triangle, a square and a regular hexagon.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses a two kinds of sled heads use as required, prize, can let shield structure machine tool changing's staff under the high-pressure environment more safe convenient efficient accomplish dismantlement, installation shield structure sword, and the detachable extension rod can be installed when using, increases the arm of force when prizing, and the shape of the human hand of laminating more of arc sled handle, the application of force of being convenient for conveniently carries, improves the efficiency and the factor of safety of staff's tool changing work.
