Hand tool for sensing current

The present invention relates to a hand tool, and more particularly to a hand tool for detecting whether the cable of the contact is energized to protect the user's safety for sensing current.

At present, the commonly used stripping tools generally include wire stripping tongs and utility knives. Usually, before stripping the power line with electric conduction, appropriate wire stripping tongs are selected according to the type and specification of the power line to be stripped. Existing power lines that are stripped of, for example, wires, telephone lines, network routes, or other current flows, and thus connected to electronic equipment such as transformers, transformers, and network outlets, must be manually completed, which is time consuming and laborious, and stripping quality. Unstable, and may even affect the poor wiring.

In addition, because the staff often encounters the inconvenience of using the detection current tool in the construction site before repairing the power or network equipment, or directly contacting the power line with the wire stripper because of the small current, and thus accidentally touching the current to cause injury. When it is necessary to additionally use a three-meter electric meter or the like to detect a current tool, it is inconvenient for the entire construction work. Therefore, since the wire stripper has the function of detecting current, it will make it easier for the worker to detect the current and achieve the purpose of warning the worker to protect it.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

One of the purposes of the present invention is to provide a hand tool for sensing current by allowing a user to sense whether a current exists in a cable through a hand tool to effectively protect worker safety.

To achieve the above objective, the present invention provides a hand tool for sensing current, including a body and a current sensing module. The body comprises two pliers handles, each pliers is pivotally connected through a pivot, two pliers at one end of each pliers handle, and a jaw structure disposed on each pliers. The current sensing module is detachably coupled to any of the jaws and disposed adjacent to the jaw structure, and the current sensing module includes a warning unit that emits a warning signal.

The creation also has the following effects. When the sensor senses a current or an electric field, the warning unit can immediately notify the worker through the installation of, for example, an LED and/or a buzzer, so that the worker can avoid accidental contact with current or electric field. Accidents increase the safety, convenience and timeliness of repairs or repairs. In addition, the current sensing module also includes a contact or non-contact sensor, the worker does not need to contact or directly contact the cable / conductor to detect the current, according to the work or needs.

The current sensing module of the present invention is detachably assembled on the opposite side of the two jaws and the front line structure, and the components of the current sensing module can be eliminated, unless the normal operation of the jaw structure is affected. Convenient replacement or repair.
