[0002] Rebar cutting equipment can be divided into handheld rebar cutters, hydraulic rebar cutters and mechanical rebar cutters. The handheld rebar cutter consists of a handle, a blade and a fixing device. It uses the principle of leverage to manually operate the handle to make the blade generate shear force on the rebar. The core component of the hydraulic rebar cutter is the hydraulic system. By applying pressure, it enters the hydraulic cylinder to push the piston to move. The piston is connected to the shear blade, thereby driving the blade to shear the rebar. The mechanical rebar cutter drives the cutter wheel to rotate at high speed through a motor, and controls the rotating cutter wheel to approach the rebar through the operating structure, thereby completing the cutting of the rebar. The mechanical rebar cutter has a simple structure, is sturdy and durable, and is widely used in general construction sites and small rebar processing workshops.

Another worker starts the road and controls the rotating cutter wheel to move toward the steel bars by operating the handle. The cutting process will cause the steel bars to vibrate under force, resulting in unstable hands of the worker who is pressing. It is also more physically demanding and dangerous. Therefore, a construction project steel bar cutting device with a protective structure is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In this embodiment, the fixing structure includes a mounting frame 51 installed on the top of the cutting base 1, and a limiting groove 52 is provided inside the mounting frame 51. Two connecting plates 53 that pass through the limiting groove 52 are slidably installed inside the mounting frame 51. The outer surfaces of the two connecting plates 53 are respectively slidably connected to the inner walls of the limiting groove 52. The outer surfaces of the two connecting plates 53 are installed with clamping blocks 54 for fixing the steel bars of the construction project. The two clamping blocks 54 are provided with fixing parts 55 for fixing the connecting plates 53. The two fixing parts 55 include two fixing screws. The interiors of the two connecting plates 53 are provided with through holes, and the interiors of the two clamping blocks 54 are provided with two threaded holes. The two fixing screws on the same side are threadedly installed in the threaded holes and one end of the fixing screw passes through the through hole, which facilitates the connection between the connecting plate 53 and the clamping block 54, and facilitates the regular replacement of worn clamping blocks 54.
[0022] Among them, the two clamping blocks 54 both include concave blocks, and one end of the two connecting plates 53 is respectively inserted into the grooves of the two concave blocks. Multiple anti-slip grooves are opened on the opposite sides of the two concave blocks, which facilitates the use of the anti-slip grooves on one side of the two concave blocks to stably clamp the steel bars of the construction project.
[0023] By adopting the above technical solution, it is possible to control the two connecting plates 53 to move to the opposite side by using the control installation structure, so that the two moving connecting plates 53 respectively drive the two clamping blocks 54 to move to the opposite side, so that the two clamping blocks 54 can firmly clamp the construction steel bars with their anti-slip grooves, thereby replacing manual work to stably fix the construction steel bars.
[0024] In this embodiment, the control installation structure includes a threaded column 56 that is rotatably installed inside the installation frame 51 and is used to control the movement of the two connecting plates 53. One end of the threaded column 56 passes through and extends to the outside of the installation frame 51. The outer surface of the threaded column 56 is fixedly connected to a handwheel 57 located outside the installation frame 51, which facilitates the rotation of the threaded column 56. The left and right sides of the installation frame 51 are provided with installation components 58 for connecting the cutting base 1. The two installation components 58 both include a mounting plate and a mounting bolt. The two mounting plates are fixedly installed on the left and right sides of the installation frame 51 respectively. One end of the mounting bolt passes through the mounting plate and extends to the inside of the cutting base 1. The mounting bolt is connected to the internal thread of the cutting base 1, which facilitates the installation of the installation frame 51 on the cutting base 1 to facilitate the fixation of the engineering steel bars.
[0025] The two sections of threads on the outer surface of the threaded column 56 are symmetrically distributed on the left and right, and the two connecting plates 53 are respectively threadedly installed on the outer surface of the threaded column 56, so that rotating the threaded column 56 can control the two connecting plates 53 to move to the opposite side or the opposite side.
[0026] By adopting the above technical solution, one end of the construction engineering steel bar is passed through the mounting frame 51 and placed on the top of the cutting base 1, and then the handwheel 57 is rotated to drive the threaded column 56 to rotate, so that the two connecting plates 53 threadedly connected on the outer surface of the threaded column 56 move to the opposite side.
[0027] The working principle of the above embodiment is:
[0028] When using the construction engineering steel bar cutting equipment with a protective structure, one end of the construction engineering steel bar is passed through the mounting frame 51 and placed on the top of the cutting base 1, and then the hand wheel 57 is rotated to drive the threaded column 56 to rotate, so that the two connecting plates 53 threadedly connected on the outer surface of the threaded column 56 move to the opposite side, and then the two moving connecting plates 53 respectively drive the two clamping blocks 54 to move to the opposite side, so that the anti-slip groove side of the two clamping blocks 54 firmly clamps the construction engineering steel bar, thereby replacing manual work to stably fix the construction engineering steel bar, and making it easier for the staff to control the rotating cutter wheel 3 to cut the steel bar.
