[0002] Bolt cutters are a common tool in today's industrial landscape, particularly in construction, bridge construction, and power engineering. Their primary function is to cut rebar or other metal wires. However, traditional manual bolt cutters require two hands to operate, requiring significant force to cut the rebar. Furthermore, the lever length of the clamp exceeds 0.5 meters, making it difficult for operators to flexibly operate them in confined spaces or at height, increasing the difficulty and complexity of the work.

[0003] Therefore, existing bolt cutters have some limitations and shortcomings. The operator needs to use both hands to apply a large force to cut the steel bars, which is labor-intensive and can easily lead to operator fatigue due to long-term work. In addition, the cutting speed and efficiency of manual bolt cutters are relatively low. Especially when a large number of cutting tasks need to be completed quickly, the efficiency of manual operation is difficult to meet the needs of modern industrial production. Utility Model Content

[0032] like Figures 1 to 6As shown, a hydraulic bolt cutter comprises a handle 1, a micro switch 2, an oil cylinder 3 and a pliers body 4. The micro switch 2 is installed at the lower part of the handle 1, and the micro switch 2 is electrically connected to the hydraulic station; the oil cylinder 3 is installed at the upper part of the handle 1, and the telescopic end of the oil cylinder 3 is connected to the pliers body 4;

[0033] The caliper body 4 includes a fixed frame 41, a connecting rod 42, a blade 43 and a connecting plate 44. The fixed frame 41 is connected to the telescopic end of the cylinder 3. A connecting rod 42 is hinged at each end of the fixed frame 41, and each connecting rod 42 is hinged to a blade 43. The two blades 43 are hinged to one end of the connecting plate 44, and the other end of the connecting plate 44 is installed on the end surface of the cylinder 3.

[0034] The hydraulic bolt cutter described in the utility model is lightweight and easy to carry. Through the cooperation of the micro switch, the oil cylinder and the hydraulic station, the hydraulic system provides shearing force, and thicker steel bars or other metal wires can be easily cut. Through the hydraulic power assistance, the hydraulic bolt cutter can greatly reduce the force required to be applied by the operator, thereby reducing labor intensity, significantly improving the shearing speed and work efficiency, and meeting the high efficiency requirements of modern industrial production.

[0035] In a preferred embodiment of the present invention, the two blades 43 are symmetrically arranged, and the cutting edges of the two blades 43 are in contact with each other in a closed state.

[0036] In actual use, the symmetrical arrangement of the blades 43 ensures that a uniform shear force is applied to the object being sheared when closed, helping to improve shearing efficiency and accuracy, and reducing tool damage or incomplete shearing caused by uneven force. The cutting edges of the two blades 43 contact each other when closed, ensuring precise alignment of the shearing points.

[0037] In a preferred embodiment of the present invention, there are two connecting plates 44 , which are respectively located on both sides of the blade 43 .

[0038] In actual use, the telescopic end of the cylinder 3, the fixing frame 41, and the connecting rod 42 are all located between the two connecting plates 44, and the blade 43 is hinged to the two connecting plates 44 at the same time, which enhances the stability of the overall structure, reduces accidental sliding or offset caused by unbalanced blades, reduces safety risks during operation, ensures uniform distribution of force during the shearing process, and reduces tool damage or incomplete shearing due to uneven force.

[0039] In a preferred embodiment of the present invention, the oil cylinder 3 is arranged horizontally, and the lower portion of the handle 1 is inclined at a certain angle to the oil cylinder 3 .

[0040] In actual use, the lower portion of handle 1 is tilted at a certain angle to cylinder 3, which makes it more ergonomic for the operator, reduces wrist and arm fatigue, and improves comfort during long-term operations. The tilted handle design also helps provide better grip stability, especially when precise control of cutting force and direction is required. This design can reduce hand slippage and improve operational stability and safety.

[0041] In a preferred embodiment of the present invention, the handle 1 is a hollow structure, and the upper portion is a circular bracket that cooperates with the oil cylinder 3.

[0042] In actual use, the hollow structure of the handle 1 can reduce the use of materials, thereby reducing the overall weight, making the tool lighter, easier to operate and carry. The handle 1 is compact and easy to hold, and can be flexibly operated in confined spaces or at heights.

[0043] In a preferred embodiment of the present invention, a guard 11 for installing a signal line of the micro switch 2 is provided at the lower portion of the handle 1 .

[0044] In actual use, a wire guide is provided at the mouth guard 11, through which the signal line of the micro switch 2 passes through the mouth guard 11 and out of the handle 1 to connect to the workstation. The design of the mouth guard 11 can effectively protect the signal line of the micro switch 2, preventing damage to the signal line due to friction, pulling or impact during use, thereby ensuring the stability and reliability of signal transmission.

[0045] In a preferred embodiment of the present invention, the button 21 of the micro switch 2 is located outside the handle 1 .

[0046] In actual use, the microswitch 2 serves as a control switch for the hydraulic station. In this embodiment, the lower portion of the handle 1 is a rectangular parallelepiped structure. The microswitch 2 is fixed to the lower inner wall of the handle 1 via an L-shaped folding plate. The fixed tube of the button 21 is connected to the microswitch 2 via a folding plate. The button 21 is slidably connected to the fixed tube. When the button 21 is manually pressed, it slides along the inner wall of the fixed tube into the handle 1 and contacts the microswitch 2. The microswitch 2 transmits a signal to the hydraulic station via a signal line, which in turn causes the hydraulic station to supply oil.

[0047] In a preferred embodiment of the present invention, the oil cylinder 3 includes an oil cylinder body and a cylinder barrel 31, the oil cylinder body is installed in the oil cylinder barrel 31, the piston rod 32 of the oil cylinder body extends from one end of the oil cylinder barrel 31 to connect to the fixing frame 41, and the other end of the oil cylinder barrel 31 is installed in the circular bracket of the handle 1.

[0048] The oil cylinder barrel 31 is provided with an oil inlet 1 33 and an oil inlet 2 34 which are connected to the oil cylinder body.

[0049] In actual use, the oil cylinder body and the oil cylinder barrel 31 are both arranged horizontally. The end face of the oil cylinder barrel 31 is connected to the circular bracket by screws, which facilitates disassembly and maintenance. When the bolt cutters are working, lightly press the micro switch 2, and the hydraulic station receives the oil supply signal 1, and supplies oil to the oil cylinder body through the oil inlet 1 33. The piston rod 32 extends, and the two blades 43 are closed under the restraint of the two connecting rods 42. Lightly press the micro switch 2 again, and the hydraulic station receives the oil supply signal 2, and supplies oil to the oil cylinder body through the oil inlet 2 34. The piston rod 32 contracts, and the two blades 43 are opened under the restraint of the two connecting rods 42.

[0050] In a preferred embodiment of the present invention, a lifting ring 5 is further included, and a screw of the lifting ring 5 is threadedly connected to the circular bracket and the oil cylinder 31 in sequence.

[0051] In actual use, a lifting ring 6 is provided for convenient storage of the bolt cutters. The lifting ring 5 can be firmly connected to the circular bracket and the oil cylinder 31 through a threaded connection, ensuring that the connection will not loosen or fall off when bearing load, thereby improving the stability and reliability of the overall structure.

[0052] Working principle of hydraulic bolt cutters:

[0053] In the initial state, the two blades 43 are in an open state; the worker holds the handle 1, aligns the jaws formed by the two blades 43 with the steel bar to be cut, and lightly presses the micro switch 2. The hydraulic station receives the oil supply signal 1 and supplies oil to the cylinder body through the oil inlet 1 33. The piston rod 32 extends, and under the restriction of the two connecting rods 42, the two blades 43 are driven to close and cut the steel bar.

[0054] After cutting, the staff presses the micro switch 2 again, the hydraulic station receives the oil supply signal 2, supplies oil to the cylinder body through the oil inlet 2 34, and the piston rod 32 contracts, so that under the restriction of the two connecting rods 42, the two blades 43 are driven to open and return to the initial state.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
