Description

Technical Field

[0001] The utility model relates to the technical field of handheld cutting machines, in particular to a handheld cutting machine. Background Art

[0002] With the development of science and technology, wires have been applied to many fields. More and more electrical appliances are needed, and the corresponding demand for wires is increasing. However, most of the current wire cutting tools are mainly pliers. When facing thicker wires, they are stressful to use and inconvenient to operate with both hands. Automatic wire cutting devices are generally desktop machines and cannot adapt to work in multiple occasions.

[0003] The publication number in the existing public technology is: CN219520346U. A handheld wire cutter includes a handle, a cutter housing, and a grip rod, and is characterized in that it includes: a cutting blade, a movable plate, a motor, a propulsion mechanism, a wire clamp block, and a clamping mechanism. The handle is fixedly connected to the cutter housing, and the grip rod is rotatably connected to the cutter housing. The wire clamp block consists of two groups of upper and lower clamp blocks, and the two groups of upper and lower clamp blocks are respectively installed on both sides of the front end of the cutter housing for stably clamping the wire. The clamping mechanism is arranged between the grip rod and the wire clamp block. The grip rod is moved to engage and clamp the wire. The movable plate is movably connected to the cutter housing, and the cutting blade is rotatably connected to the movable plate. The motor is arranged on the movable plate for driving the cutting blade to rotate. The propulsion mechanism is installed on the movable plate, and the movable plate can be adjusted to move forward and backward by the propulsion mechanism.

[0004] However, the above patent still has certain shortcomings when used: when cutting the wires, personnel are required to drag and move the wires, which is time-consuming and labor-intensive, and manual movement cannot effectively control the length of the wires, which leads to a certain error between the subsequent required length and the actual cut length, resulting in the cut wires being unsuitable or requiring secondary cutting, which reduces the overall cutting effect. The actual use quality is not very ideal, and the area where the wires are cut is in a suspended state, which is prone to dislocation when squeezed, thereby affecting the overall cutting effect.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
