Description

Technical Field

[0001] This utility model relates to the field of electric rebar shearing pliers, and in particular to a portable electric rebar shearing pliers. Background Technology

[0002] In many fields such as construction, rebar processing, and emergency rescue, rebar cutters are indispensable tools for efficiently and accurately cutting various types of rebar. Traditional rebar cutters are mainly of two types: manual and hydraulic. Manual rebar cutters rely on manual operation, are inexpensive and easy to use, but are extremely inefficient and labor-intensive, suitable only for small-scale rebar cutting operations. Hydraulic rebar cutters, powered by a hydraulic system, can easily cut larger diameter rebars, meeting the needs of high-strength, continuous cutting; however, they generally rely on an external power source, limiting their range of motion.

[0003] With the increasing popularity of power tool technology, electric rebar cutters have emerged. Powered by an electric motor, they offer advantages such as relatively simple operation and high cutting efficiency. Currently, most electric rebar cutters on the market use a fixed power supply mode, either relying on an electric cord connected to a power outlet or having a built-in, non-removable, high-capacity battery.

[0004] Both power supply methods have significant drawbacks. For the former, the electrical connection severely restricts the range of motion of the cutting pliers, making them difficult to maneuver in complex construction environments. Furthermore, the electrical wires themselves are highly susceptible to damage. Damage to the wires can lead to power outages, affecting construction progress, and potentially causing electrical leaks and other safety accidents, threatening the lives of operators. While electric rebar cutting pliers with built-in non-removable batteries are free from the constraints of electrical cords, their limited battery life cannot meet the requirements of extended operation. In continuous, high-intensity rebar cutting scenarios, the inability to quickly replace a depleted battery, requiring waiting for it to recharge, leads to work interruptions and significantly reduces work efficiency. This power supply method lacks flexibility, struggles to adapt to changing construction site conditions, and cannot replenish the cutting pliers' power in a timely manner, thus impacting project progress.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please refer to Figures 1 to 3 The present invention provides a portable electric rebar cutter as shown in the figure, comprising a cutter body 1, a battery module 9, and a quick-release structure.

[0025] The shearing pliers body 1 is the core component of the shearing pliers, which integrates a motor and a cutting tool 2. The motor output in the shearing pliers body 1 drives a cutting head, while the cutting tool 2 includes a cutting tool holder located at the front end of the shearing pliers body 1. The cutting tool holder can hold a reinforcing bar and is positioned by bolts. The cutting head and the cutting tool holder work together to cut the reinforcing bar.

[0026] A power interface 6 is electrically connected to the motor input end of the shearing pliers body 1. This interface 6 serves as an external power access point, providing power support for the motor operation. One end of the battery module 9 is electrically connected to an interface line 14. The interface line 14 and the power interface 6 are connected in a pluggable manner. This structural design facilitates the quick connection and separation of the battery module 9 and the shearing pliers body 1, improving the flexibility and convenience of use.

[0027] Battery module 9 uses BSL1830 batteries and is equipped with a Type-C power interface, which is not only compatible with a variety of charging devices, but also serves as a universal interface for connecting with other devices, ensuring a stable connection between battery module 9 and shearing pliers body 1.

[0028] Specifically, the quick-release structure includes a first locking frame 5, a second locking frame 11, an elastic element 15, and two locking blocks 12. The first locking frame 5 is fixedly disposed at one end of the shearing pliers body 1, and the second locking frame 11 is disposed at one end of the power interface 6 and can be stably engaged with the first locking frame 5.

[0029] The two locking blocks 12 are movably set inside the second locking frame 11 by means of the elasticity of the elastic element 15. Two locking slots 7 are correspondingly opened on the first locking frame 5. When the second locking frame 11 is fastened to the first locking frame 5, the locking blocks 12 will be pushed by the elastic element 15 to achieve precise engagement with the corresponding locking slots 7, thereby achieving a stable connection between the battery module 9 and the shearing pliers body 1.

[0030] Based on the above embodiments, please refer to Figure 4 and Figure 5 The locking block 12 consists of a main body block 121, a sliding pin 122, and a locking hook 123. The sliding pin 122 is located on one side of the main body block 121, and the locking hook 123 is located on the upper part of the main body block 121. The hook-shaped part of the locking hook 123 is triangular, with the hook opening facing the sliding pin 122. This design allows the locking hook 123 to be securely engaged with the locking slot 7. At the same time, by squeezing the hook-shaped part of the locking hook 123, its sliding direction can be forced to be the same as that of the sliding pin 122.

[0031] Meanwhile, pin openings are provided on both sides of the second card frame 11, and the sliding pin 122 is slidably connected to the pin opening. The width of the main block 121 is greater than the size of the pin opening, thereby restricting the movement of the card block 12 in the second card frame 11, preventing the card block 12 from falling off, and improving the stability and reliability of the structure.

[0032] Based on the above embodiments, the elastic element 15 is selected as a spring, which can provide a stable thrust for the locking block 12. A mounting hole 16 is provided on the other side of the main block 121 away from the sliding pin 122, and a limit block 13 is provided in the middle of the second locking frame 11.

[0033] One end of the elastic element 15 is connected to the mounting hole 16, and the other end is connected to the limiting block 13, which makes the installation and fixation of the spring more secure, and also facilitates the compression and reset of the spring, thereby improving the smoothness of the engagement and disengagement of the locking block 12 and the locking slot 7.

[0034] In an optional embodiment, a first positioning frame 4 is provided at the end of the shearing pliers body 1, and a second positioning frame 8 is provided at the corresponding end of the battery module 9. The power interface 6 is connected to the first positioning frame 4, and the interface cable 14 is connected to the second positioning frame 8.

[0035] More specifically, the power interface 6 is fixed through the middle of the first positioning frame 4, and the interface cable 14 is fixed through the middle of the second positioning frame 8 to ensure that the power interface 6 and the interface cable 14 are in the correct positions. This ensures a stable connection between the power interface 6 and the interface cable 14 when they are plugged into each other, avoiding poor contact caused by unstable plugging and improving the reliability of the cutting pliers.

[0036] A handle 3 is provided on the outer side of the cutter body 1, and a handle 10 is provided on the other end of the battery module 9 away from the second positioning frame 8. Both the handle 3 and the handle 10 are used to facilitate the user to move the cutter.

[0037] The working principle of the above embodiments is as follows: When installing the power module 9, the second frame 11 and the first frame 5 are pressed and engaged directly. During the insertion process, the first frame 5 presses the block 12 located inside the second frame 11. At this time, the block 12 contacts the first frame 5 through the hook 123, causing the hook 123 to retract and retract. The first frame 5 is then fully inserted into the second frame 11. Under the elastic force of the elastic element 15, the sliding pin 122 slides relative to the second frame 11, thereby causing the hook 123 to reset and engage at the slots 7 on both sides of the first frame 5. This allows the battery module 9 to be quickly and easily connected to the cutting pliers body 1. At the same time, the handle 10 at the end of the battery module 9 can be held to use the cutting pliers. When it is necessary to replace or remove the battery module 9, the sliding pins 122 on both sides of the second frame 11 are pressed simultaneously, forcing the block 12 to retract and separating the power module 9 from the cutting pliers body 1.

[0038] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0039] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
