The utility model solves the problem that the economic consumption of a user is increased because the user can only replace the whole plier head and cannot independently replace the plier blade part due to the fact that the plier head and the plier blade are mostly of an integrated structure when the steel bar shears are used for a long time and the plier blade on the plier head is greatly abraded. And the problem that due to the fact that the length of the pincer handles of the steel bar shears cannot be adjusted, it is difficult to cut off steel bars at the high position is solved.

Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar clamping and cutting devices, in particular to a steel bar clamping and cutting device for a construction site. Background Art

[0002] A rebar shear, also known as a rebar shear or a rebar shear, is a tool specifically used to shear metal materials such as rebar. It usually has two main parts: an upper jaw and a lower jaw.

[0003] The upper jaw is mainly used to clamp the steel bar, and its design usually includes a jaw and a jaw. The jaw is U-shaped to clamp the steel bar, while the jaw is mostly V-shaped or semicircular to ensure that the steel bar does not slip or slide during the cutting process.

[0004] The lower jaw is responsible for cutting the rebar and is more complex. It consists of a blade, a backing, a pressure plate, and a baffle. The blade, usually diamond-shaped, is the part that actually cuts the rebar. The backing holds the blade in place and is usually a spring or a number of small metal pieces. The pressure plate assists in cutting the rebar by holding it down so it is easier to cut. The baffle holds the lower jaw in place to prevent it from breaking or moving.

[0005] During long-term use, the blades on the pliers head of traditional rebar shears will produce a lot of wear. Because the pliers head and the blades are mostly an integrated structure, users can only replace the pliers head as a whole and cannot replace the blades separately, which increases the user's economic consumption. In addition, traditional rebar shears cannot adjust the length of the pliers handle, which makes it more difficult to cut rebars at higher positions. We propose a rebar clamping device for construction sites. Utility Model Content
