Technical Field
[0001] This utility model relates to the field of pry bar technology, specifically to a lightweight pry bar. Background Technology
[0002] A crowbar is a tool that uses leverage to lift heavy objects off the ground and move them by overcoming gravity. It is a commonly used hand tool in construction sites, machinery repair, metal structure fabrication, and cargo handling.
[0003] However, current pry bars are all one-piece solid structures, generally made of solid iron bars. They are not only fixed in size but also heavy and cannot be extended, making them tiring to use and inconvenient to carry and use. When dealing with different angles or situations where the prying space is limited, it is necessary to replace the pry bar with one of different pry head types because the end joint is fixed.

[0007] Preferably, the pry tool further includes a pry head connecting block, which is an integral part of the nail-removing head. The pry head connecting block and the nail-removing head are in the form of a straight rod, an acute angle, or a right angle. An installation joint is provided between the pry head connecting block and the pry bar.
[0008] Preferably, one or both ends of the pry bar are provided with internal threaded holes, and the mounting joint is fixed to the pry bar by welding or threading.
[0009] Preferably, the pry bar has at least one section, and two adjacent pry bars are extended by a direct or indirect structure; the rear end of the pry bar is provided with at least one extension bar, both ends of the pry bar are provided with internal threaded holes, one end of the extension bar is provided with an internal threaded hole, and the other end of the extension bar is provided with a threaded head; a connecting joint is provided between two adjacent pry bars, and the connecting joint is a threaded joint or a quick-change structure joint to lengthen and fix the pry bar.
[0010] Preferably, the outer end face of the pry bar is provided with a plurality of lightweight grooves I distributed at intervals along the pry bar.
[0011] Preferably, both ends of the lightweight groove I or the lightweight groove I are provided with anti-slip flanges that are integrated with the outer circle of the pry bar.
[0012] Preferably, the front end of the nail puller is provided with a nail puller groove, and the rear end face of the nail puller is provided with a lightweight groove II.
[0013] Preferably, the outer circumference of the pry bar is provided with knurling, and the knurling shape is straight knurling, diagonal knurling, or mesh knurling.
[0014] Preferably, the pry bar is provided with an anti-slip sleeve that is partially or completely nested and connected to the pry bar, and the anti-slip sleeve is made of rubber or plastic.
[0015] Preferably, the nail-removing head has a round head structure, a flat head structure, a pointed head structure, a bladed structure, or a bladeless structure.
