Description

Needle nose pliers with wire stripping function

technical field

The utility model relates to a needle-nose pliers tool, in particular to a needle-nose pliers with a wire stripping function which is suitable for electricians and can be used for stripping wires.

Background technique

The main job of an electrician is wiring, connecting various wires, and connecting electrical equipment to the grid. Due to the different types and specifications of electrical equipment, the types of wires required are also different, and most of these wires require glass insulation sheaths to connect, so electricians need to continuously strip the wires. The existing wire stripping method for electricians is to operate with a hand-held wire stripper. The function of the existing wire stripper is relatively single, only stripping the wire. The electrician will also use other tools when working, such as needle-nose pliers, Because the cross-sectional size of the front end of the needle nose pliers is gradually reduced, it can enter a relatively narrow space for operation. The end of the wire with the insulation sheath stripped off is short and inconvenient to pinch directly by hand, so it is often held by needle-nose pliers. In this way, wire strippers and needle-nose pliers need to be replaced back and forth, which is troublesome to operate.

There are several semicircular grooves with different diameters between the straight plane of the left pliers body and the hinged part. There are several semicircular grooves with different diameters between the straight plane of the pliers body and the hinged part. The grooves on the left pliers body correspond to the positions of the grooves on the right pliers body. Closed circle, the edge of the groove is a sharp edge, and the diameter of the groove near the hinge is larger. The semicircular grooves are combined to form a notch for stripping wires, which makes the needle-nose pliers increase the function of stripping wires. When using it, electricians do not need to switch between needle-nose pliers and wire strippers, and the operation is convenient; the groove is in the The front end position of the hinged part can better ensure the accuracy of the matching of the grooves during processing, thereby ensuring the accuracy of the stripping notch.

Preferably, the overall shape from the hinged part to the front end after the left pliers body and the right pliers body are closed is triangular.

Preferably, a straight-edged sharp edge is provided between the groove of the left pliers body and the hinged part, a straight-edged sharp edge is provided between the groove of the right pliers body and the hinged part, and the sharp edges of the left pliers body and the right pliers body are combined to form a wire sheared parts. The straight-edged sharp edge is convenient for splitting the insulation sheath of the wire and cutting off the metal wire inside the wire.

Preferably, a torsion spring for opening the jaws is provided at the hinged position of the left pliers body and the right pliers body, and the two ends of the torsion spring are respectively fixed to the left pliers body and the right pliers body. The torsion spring drives the left and right pliers to open automatically, which is convenient for electricians to operate.

As a preference, one end of the handle of the needle-nose pliers near the hinge is provided with a crimping portion, the crimping portion includes a crimping convex portion and a crimping concave portion, and the crimping convex portion and the crimping concave portion are respectively arranged on the right pliers body and the left pliers physically. The wire crimping part is convenient for crimping wires, and it is convenient for electricians to connect special connectors.

Preferably, the two handles of the needle-nose pliers are provided with a jaw closing buckle near the hinged part, the buckle is in the form of a sheet, the end of the buckle is provided with a bent part, and the side of the buckle is provided with a push part, The bending direction of the bending part is opposite to that of the pushing part, and the hasp is hinged to the left or right tong body through a pin shaft, and the corresponding right or left tong body is provided with a locking groove with an open end. The locking groove fits into the bend. The left pliers body and the right pliers body can be closed by the hasp, preventing the jaws from opening, especially preventing the sharp ends from hurting people when the jaws are opened.

Preferably, serrations with a triangular cross-section are provided on the outer side of the left pliers body and the outer side of the right pliers body, and the length direction of the serrations is perpendicular to the length direction of the needle-nose pliers. The saw teeth form the friction part, and the electrician can complete the work of grinding or deburring with needle-nose pliers.

The beneficial effects of the utility model are: the semicircular grooves are combined to form a notch for stripping wires, so that the needle-nose pliers can increase the function of stripping wires, and the electrician does not need to be between the needle-nose pliers and the wire strippers when using It is easy to switch and operate; the groove is at the front end of the hinged part, which can ensure the accuracy of the groove alignment during processing, thereby ensuring the accuracy of the stripping notch.
