[0023] The utility model will be further described below in combination with the drawings and examples:

[0024] Example one: see Figure 1 、 2 A reinforcing steel cutting device, including handheld cutting machine 1, still including bottom plate 2, support 3 and tension spring 4, handheld cutting machine 1 is connected with bottom plate 2 through support 3;

[0025] The right end of support 3 is rotatably connected to the top right side of bottom plate 2, and the left end of support 3 is fixedly connected to the top right side of handheld cutting machine 1, and the right end of handheld cutting machine 1 is provided with a cutting wheel 5, and a notch 6 is arranged on the bottom plate 2, and the cutting wheel 5 is arranged opposite to the notch 6.

[0026] A first bolt 7 is arranged on the bottom plate of the right end of support 3, a second bolt 8 is arranged on the top left side of support 3, and the two ends of tension spring 4 are respectively connected to the first bolt 7 and the second bolt 8.

[0027] In this embodiment, the handheld cutting machine includes a shell, a handle 9, a motor and a cutting wheel, an electric wire 10 passes through the handle and the shell and is connected with the motor, the motor is installed in the shell, the right end of the handle is connected with the left end of the shell, the cutting wheel is arranged at the front end of the shell and is connected with the motor, the motor drives the cutting wheel to rotate, and the left side bottom surface of the support is connected with the top of the shell. Due to the existence of the tension spring, the tension spring will pull the support to rotate clockwise around the bottom plate, so that the support is arranged to be inclined upward from right to left, in this state, the handheld cutting machine is also arranged to be inclined upward from right to left, and the plane where the bottom outer surface of the cutting wheel is located is above the top plane of the bottom plate, then the reinforcing steel bar is placed on the bottom plate, the position to be cut is opposite to the gap and is below the cutting wheel, then the operator holds the handle of the handheld cutting machine and gives it a downward pressure, which drives the support to rotate counterclockwise around the bottom plate and moves the cutting wheel downward (the motor of the handheld cutting machine works and drives the cutting wheel to rotate at a high speed), the reinforcing steel bar is cut off through the cutting wheel rotating at a high speed, when the plane where the bottom outer surface of the cutting wheel is located is in the gap, the reinforcing steel bar can be cut off. After cutting, the downward pressure of the handheld cutting machine is released, the tension spring pulls the support to rotate clockwise, so that the handheld cutting machine automatically moves upward and is separated from the gap, then the operator continues to move the reinforcing steel bar forward, so that the position to be cut continues to be opposite to the cutting wheel, and waits for the next cutting. In this way, the cutting efficiency is high, and the labor intensity of the operator is low, and the operator only needs to give the handheld cutting machine a downward pressure to realize the cutting of the reinforcing steel bar.

[0028] Referring to Figure 1 , 2 As shown in the figure, the bottom plate 2 is provided with a baffle 11, the baffle 11 is arranged at the rear side of the gap 6, and the baffle 11 is arranged parallel to the axis of the cutting wheel 5.

[0029] When the cutting wheel of the handheld cutting machine is close to the gap, the baffle 11 is arranged at the right side of the axis of the cutting wheel 5.

[0030] The baffle is arranged, when the reinforcing steel bar is placed on the bottom plate, the side of the reinforcing steel bar is abutted against the baffle, so that the cutting position of the reinforcing steel bar is opposite to the cutting wheel, the reinforcing steel bar cannot be inclined, the cutting position is basically perpendicular to the reinforcing steel bar, and the cutting effect is guaranteed. Meanwhile, the baffle also plays a role in positioning the cutting of the reinforcing steel bar, the operator can hold the reinforcing steel bar with the other hand to make the reinforcing steel bar abut against the baffle or step on the reinforcing steel bar to make the reinforcing steel bar abut against the baffle, so that the reinforcing steel bar cannot move in the cutting process, only the pressure to the right of the reinforcing steel bar is needed, the cutting effect is guaranteed, and the safety hidden danger caused by the shaking and rotation of the reinforcing steel bar in the cutting process is prevented.

[0031] Referring to Figure 1 , 2As shown, the support 3 comprises a connecting shaft 12 and a connecting plate 13, the connecting shaft 12 is arranged parallel to the axis of the cutting wheel 5, both ends of the connecting shaft 12 are rotationally connected with the bottom plate 2, the right end of the connecting plate 13 is connected with the outer surface of the middle part of the connecting shaft 12, the left end of the connecting plate 13 is abutted on the top surface of the right end of the handheld cutting machine 1, and the left end of the connecting plate 13 is connected with the handheld cutting machine 1 through the second bolt 8.

[0032] In this embodiment, the second bolt is at least two, preferably two, and the left end of the tension spring is connected with one of the second bolts. Among them, the second bolt is screwed and fixed with the connecting plate and the shell of the handheld cutting machine. This not only facilitates the connection of the support and the handheld cutting machine, but also facilitates disassembly. When not in use, the handheld cutting machine can be disassembled for normal use.

[0033] In this way, the firmness of the connecting plate and the handheld cutting machine after connection is ensured, so that the handheld cutting machine will not rotate relative to the connecting plate. And the support adopts the combination of connecting shaft and connecting plate, which has simple structure and low cost, and can obtain materials conveniently and weld quickly on the construction site.

[0034] Referring to Figure 1 , 2 As shown, the top right side of the bottom plate 2 is provided with two positioning blocks 14 arranged in front and back, and both ends of the connecting shaft 12 are rotationally connected with the two positioning blocks 14. The positioning block is arranged for the rotational connection of the connecting shaft, which can lift the bottom of the connecting shaft away from the bottom plate, facilitating the rotation of the connecting shaft relative to the bottom plate.

[0035] Among them, the first bolt is arranged on the bottom plate at the right end of the connecting shaft. The first bolt is arranged obliquely from bottom to top and to the right. In this way, when the right end of the tension spring is directly turned to the right, the right end of the tension spring will not be separated from the first bolt, so that the support remains in an inclined state.

[0036] The front end of the gap is connected with the front side wall of the bottom plate. In this way, after the steel bar is cut off, it can fall from the gap without the need for manual pushing of the cut-off steel bar from the top of the bottom plate, reducing the action of the operator and reducing the labor intensity.

[0037] Referring to Figure 1 As shown, the bottom left and right sides of the bottom plate 2 are respectively provided with support members 15, and the support members 15 on both sides are arranged on both sides of the gap 6.

[0038] The support is arranged to lift the bottom plate, facilitate the operator to operate, and make the operator not need to squat to operate, but can stand or sit to operate, improve the convenience of operation, and also lift the bottom plate, and the steel bars after cutting can directly fall on the ground.
