[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-5 As shown, a highly reliable rebar cutter includes a trolley 1. A connecting cover 2 is fixedly installed on one side of the upper surface of the trolley 1. Two sliding rods 3 are slidably arranged through one side of the inner wall of the connecting cover 2. A movable plate 4 is fixedly installed at one end of the two sliding rods 3.

[0025] A first cutter 5 is slidably installed through one side of the inner wall of the connecting cover 2. One end of the first cutter 5 is fixedly connected to the moving plate 4. A cylinder 6 is fixedly installed on the other side of the inner wall of the connecting cover 2. The output end of the cylinder 6 is fixedly connected to the moving plate 4.

[0026] A second cutter 7 is fixedly mounted on the other side of the upper surface of the cart 1 via a cutter holder;

[0027] The upper surface of the trolley 1 is provided with a protective component 8 for protection.

[0028] The protective component 8 includes a stepped groove 801, which is formed on the upper surface of the trolley 1. A stepped block 802 is slidably disposed in the stepped groove 801, and a protective plate 803 is fixedly installed on the upper surface of the stepped block 802.

[0029] The operator starts the cylinder 6, which drives the first cutter 5 to move. The first cutter 5 can move and work with the second cutter 7 to cut the steel bar. During the cutting, the operator controls the step block 802 to move, which drives the protective plate 803 to move. The protective plate 803 can then shield the cut part of the steel bar, thus separating it from the operator and improving reliability.

[0030] In another embodiment of this utility model, a lead screw 9 is rotatably installed between the two sides of the inner wall of the stepped groove 801, the stepped block 802 is threaded on one side of the lead screw 9, and a motor 10 is fixedly installed on one side of the trolley 1.

[0031] The operator starts the motor 10, which causes its output shaft to drive the lead screw 9 to rotate. The rotating lead screw 9 drives the stepped block 802 to move along the stepped groove 801 by screwing in, thereby driving the protective plate 803 to move.

[0032] In another embodiment of this utility model, upright plates 11 are fixedly installed on both sides of the top of the connecting cover 2, and a switch button 12 is provided on the opposite side of the two upright plates 11. The switch button 12 is electrically connected to the motor 10.

[0033] A support frame 13 is fixedly installed on the upper surface of the movable plate 4, and a connecting column 14 is fixedly installed on each side of the support frame 13 that is far apart from each other.

[0034] As the first cutter 5 moves, the connecting column 14 contacts one of the switch buttons 12, causing the motor 10 to start and the protective plate 803 to move. After cutting is completed, the connecting column 14 will disengage from one of the switch buttons 12 and then contact the other switch button 12, causing the protective plate 803 to move away, making it convenient for workers to remove the steel bars.

[0035] In another embodiment of this utility model, rubber blocks 15 are fixedly installed at both ends of the connecting column 14.

[0036] By setting the rubber block 15, the wear caused by the connecting post 14 pushing the switch button 12 is reduced.

[0037] In another embodiment of this utility model, a baffle 16 is fixedly installed on one side of the protective plate 803.

[0038] By setting up baffle 16, the shielding range is increased and the reliability is improved.

[0039] The working principle of this highly reliable rebar cutter:

[0040] In use, the operator starts the cylinder 6, which drives the first cutter 5 to move. The first cutter 5 can move and work with the second cutter 7 to cut the steel bar. During cutting, the operator controls the step block 802 to move, which drives the protective plate 803 to move. The protective plate 803 can then shield the cut part of the steel bar, thus separating it from the operator and improving reliability.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
