[0005] In view of the above problems, it is urgently necessary to carry out innovative design based on the original H-beam simple cutting device structure. Utility Model Content

If it is not fixed, the steel is easily blown away during cutting, thereby causing harm to the surrounding workers.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simple H-beam cutting device, comprising a base, a coaxial shaft is fixedly installed on the outer side of the base, a handle is nested on the outer side of the coaxial shaft, and a cutting wheel is fixedly installed on the outer side of the handle; a fixed clamping block, the fixed clamping block is fixedly installed on the upper end of the base; a clamping assembly, the clamping assembly is installed on the inner side of the fixing frame, and the fixing frame is fixedly installed on the upper end of the base; an H-beam workpiece, the H-beam workpiece is arranged between the fixed clamping block and the clamping assembly; a reset assembly, the reset assembly and the handle are distributed in upper and lower correspondence, wherein, by rotating the clamping assembly, the H-beam workpiece can be fixed to the upper end of the base through the cooperation between the clamping assembly and the fixed clamping block; through the resistance of the upper end of the reset assembly to the handle, the handle can be separated from the H-beam workpiece without being subjected to force.

[0008] Preferably, the clamping assembly includes a threaded rod, a threaded connector, a connecting rod and a sliding block, the threaded rod is rotatably connected to the inner side of the fixed frame, and the outer side of the threaded rod is threadedly connected to a threaded connector, connecting rods are symmetrically installed at the front and rear ends of the threaded connector, and sliding blocks are fixedly installed at the tail ends of two groups of connecting rods, and the sliding blocks and the fixed blocks are distributed in left and right correspondence.

[0009] Preferably, the clamping assembly further comprises a sliding rod and a sliding groove, wherein the sliding rod is fixedly mounted at the front and rear ends of the threaded connector, the sliding rod is nested inside the sliding groove, and the sliding groove is provided inside the fixing frame.

[0010] Preferably, the clamping assembly further comprises a rotating disk and a clamping slot, the rotating disk is fixedly mounted on the outside of the threaded rod, and the clamping slots are provided at equal angles on the inside of the rotating disk.

[0013] Preferably, the reset assembly further comprises a gasket, which is fixedly mounted on the top of the adjusting rod, and the gasket is placed at an angle of 45°, and the gasket and the bottom of the handle are distributed in correspondence with each other up and down.

[0014] Compared with the prior art, the utility model has the beneficial effect that the H-beam simple cutting device is provided with:

[0015] 1. Clamping structure. When the H-shaped steel workpiece needs to be cut, the H-shaped steel workpiece is first placed between the fixed clamp block and the sliding clamp block, and then the clamp rod is pulled to separate the tail end of the clamp rod from the clamping groove inside the rotating disk. After separation, the rotating disk is rotated to drive the threaded rod to rotate. The rotation of the threaded rod will drive the threaded connector connected to the outer thread to move left and right. The left and right movement of the threaded connector causes the connecting rod to push the sliding clamp block to move outward. The sliding clamp block cooperates with the fixed clamp block to clamp both sides of the H-shaped steel workpiece to prevent the H-shaped steel workpiece from being knocked away during cutting.

[0016] Furthermore, when the position of the sliding block is adjusted, the card rod is released, and the card rod is reset by the elastic force of the telescopic spring, so that the tail end of the card rod is engaged with the corresponding card slot, and the engagement between the card slot and the tail end of the card rod fixes the rotating disk to prevent the sliding block from moving;

[0017] 2. Reset structure. After the H-beam workpiece is fixed, the handle is pressed down so that the cutting wheel running on the outside of the handle contacts the outside of the H-beam workpiece to cut the H-beam workpiece. At the same time, when the handle is rotated downward, it contacts the reset component at the lower end. The reset component limits the rotation angle of the handle to prevent the handle from rotating too much and contacting the ground.

[0018] Furthermore, when the H-shaped steel workpiece is cut, the handle is released. After the handle loses the squeezing force, the adjusting rod on the inner side of the reset assembly pushes the gasket upward through the elastic force of the reset spring. When the gasket moves upward, the upper handle will be lifted, so that the handle will automatically rotate to its original position through the concentric axis, saving manpower.
