Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The specific embodiment is as follows:
as shown in fig. 1-2, a crowbar with adjustable fulcrum height comprises: pry bar 1, bracing piece 2, telescopic link 3, locking structure 4. Wherein, the tip of pinch bar 1 is provided with pinch bar 11, and pinch bar 1 structure as an organic whole, the tip of pinch bar 11 is crooked platykurtic structure, is convenient for stretch into treat prying in the space of prefabricated wall body and ground. The middle lower part of the pry bar 1 is provided with a pair of connecting lugs 12, and the support rod 2 is hinged to the connecting lugs 12, so that the support rod 2 can be connected to the end part of the pry bar 1 to rotate. The position of the pry bar 1, which is located at the lower part of the connecting lug 12, is also provided with a limiting slide way 13, the limiting slide way 13 is arranged along the direction of the pry bar 1, the limiting slide way 13 is two strip plates which are parallel to each other, the middle part of each strip plate is provided with a sliding groove 14, and the sliding groove 14 is parallel to the pry bar 1. Wherein, the limiting slide 13 is supported by an iron plate and is fixed on the pry bar 1 by welding.
In this embodiment, the upper end of the support rod 2 is provided with a through hole, and the upper end extends into the connecting lug, that is, the upper end of the support rod 2 is movably connected to the pry bar 1 through a bolt, and the lower end is used for supporting on the bottom surface.
