[0002] In the work environment of electronic repair or electronic experimentation, multiple tools are often required, such as multimeters, soldering irons, and electric screwdrivers. These tools are independent and are used for measuring electrical parameters, performing soldering operations, and removing and installing screws. Traditional tool combinations are often large, and each tool requires an independent power supply, making them bulky and unportable during use. In addition, traditional soldering irons and electric screwdrivers usually require a 220V AC power supply, which further limits their mobility, making them particularly difficult to use outdoors or in environments where power is inconvenient.

[0003] Existing multifunctional tools often simply combine functions without integrating and optimizing them. This results in low efficiency, cumbersome tool switching, and a lack of effective coordination between functional modules. Furthermore, traditional tools often lack effective user feedback mechanisms during use, making it difficult for users to receive clear prompts during operation, compromising safety and convenience.

[0028] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0029] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0030] like Figure 1-Figure 4 As shown, the utility model is a three-in-one tool with an electric soldering iron, an electric screwdriver and a multimeter, comprising a multimeter body 1, wherein the multimeter body 1 has a built-in power supply;

[0031] It also includes a display screen 5, which is provided on the multimeter body 1 and is used to display operating status and parameters;

[0032] When the electric soldering iron handle 6 is needed, it is only necessary to insert the plug of the electric soldering iron handle 6 into the multimeter body 1. At this time, it can be used to realize the welding function. Specifically, the electric soldering iron handle 6 is inserted, the electric soldering iron gear is selected, the welding temperature is set, and welding is started; the soldering iron temperature and setting are synchronously displayed on the screen, and the soldering iron handle can support the replacement of the soldering iron tip;

[0033] When the electric screwdriver handle 7 is needed, it is only necessary to insert the plug of the electric screwdriver handle 7 into the multimeter body 1. At this time, it can be used to realize the screw disassembly and assembly function. Specifically, insert the electric screwdriver handle 7, select the screwdriver gear, and start disassembling and assembly of screws; the screwdriver handle can support forward and reverse rotation and replacement of various types of screwdriver heads;

[0034] When current and voltage measurements are required, the measuring probes can be electrically connected to the multimeter body 1 for electrical parameter measurements. This is a common function of current current and voltage meters, and how to perform current and voltage tests will not be described in detail here. Specifically, insert the measuring probes, select the multimeter measurement position, and measure parameters such as AC and DC voltage, resistance, capacitance, and frequency. The probes send the measurement signal into the sampling circuit and then into the multimeter chip for calculation and processing to generate measurement readings. The MCU reads the measurement readings of the multimeter chip and displays them on the display screen 5.

[0035] It also includes a multifunctional control module, which is arranged in the multimeter body 1 and is used to select and control the operating modes of the electric soldering iron handle 6, the electric screwdriver handle 7 and the measuring probes;

[0036] It also includes a prompt component, including a light and sound prompt module, for indicating the operating status and power status.

[0037] The electric soldering iron handle 6 , the electric screwdriver handle 7 and the measuring probes are respectively connected to the connection port 3 of the multimeter body 1 through a plug-in device to achieve electrical connection and function switching.

[0038] The device also includes a Type-C charging port for charging the multimeter's internal power supply and supporting data communication. A red light illuminates during charging, and turns blue when fully charged. The battery voltage is fed through a step-up and regulated power supply system to the MCU, multimeter chip, soldering iron tip, electric screwdriver, and associated circuits.

[0039] Specifically, the multifunctional control module includes a function gear switching switch 2 for switching between the multimeter measurement mode, the soldering iron mode and the electric screwdriver mode. The prompt component includes a light prompt and a buzzer for providing visual and auditory prompts. The display screen 5 displays the current operating mode and parameters of the tool through the control module.

[0040] like Figure 3 and Figure 4 As shown, the multimeter body 1 is provided with a 3V voltage stabilizing circuit for voltage regulation and a 12V boost stabilizing power supply system for providing the functions of an electric soldering iron and an electric screwdriver.

[0041] The electric soldering iron handle 6, the electric screwdriver handle 7 and the measuring probe are connected to the multimeter body 1 through a retractable spring wire 4, and the spring wire is used for easy pulling.

[0042] like Figure 4 As shown, the present invention is internally provided with a 3.7V lithium-ion battery as the main power source, and provides appropriate voltage output for functional modules such as the multimeter, the electric soldering iron handle 6, and the electric screwdriver handle 7 through a 3V voltage regulator circuit and a 12V boost voltage regulator power supply system.

[0043] The multi-function control module (MCU) manages power distribution and controls power switching and supply based on the user's selected function mode. For example, when the user selects the soldering iron function, the MCU will power the soldering iron handle 6 through the 12V boost and regulated power supply system.

[0044] The tool is equipped with a function gear switch 2, which is electrically connected to the multi-function control module. When the user operates the switch to select a function mode, the switch transmits a selection signal to the MCU, which activates the corresponding function module based on the signal.

[0045] Specifically, if the user selects the multimeter function, the MCU will activate the multimeter measurement circuit and shut down other functional modules to avoid unnecessary power consumption; if the user selects the electric screwdriver function, the MCU will switch to the 12V power supply system and control the rotation direction and speed of the screwdriver, such as Figure 3 shown.

[0046] When the multimeter function is selected, the MCU will control the multimeter sampling input circuit to measure parameters such as voltage, resistance, and capacitance. The measurement results are processed by the MCU and transmitted to the LCD drive circuit, and finally displayed on the LCD screen for user convenience.

[0047] As an output device of the multi-function control module, the LCD screen is not only used to display the measurement results of the multimeter, but also can display the operating status and related parameters of the tool in different modes.

[0048] The multi-function control module is also connected to the prompt components (including lights and a buzzer). When the tool switches to a different function mode, the MCU will use the light prompt module to light the corresponding indicator light and the buzzer will sound, prompting the user that the currently selected function is ready.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
