Portable multifunctional wrench

Abstract

The invention discloses a portable multifunctional wrench. The portable multifunctional wrench comprises a bending type handle, a first screw cap, a second screw cap, a third screw cap and a connecting piece, wherein one end of the bending type handle is fixedly connected to the first screw cap, and a first connecting part is arranged at the other end of the bending type handle; a second connecting part is arranged at one end of the connecting piece, a third connecting part is arranged at the other end of the connecting piece, and the second connecting part and the third connecting part are both connected to the first connecting part in a matched manner; the first screw cap, the second screw cap and the third screw cap are screw caps of different types. The portable multifunctional wrench has the advantages that the bending type handle is easy to operate and convenient for exerting force; the second screw cap and the third screw cap are respectively fixed at the two ends of the connecting piece, the two ends of the connecting piece can be connected to the bending type handle in the matched manner, and the connecting manner of the connecting piece and the bending type handle is changed, and the second screw cap and the third screw cap can be respectively used. In addition, the portable multifunctional is wide in application range, simple in structure, small in size and convenient to carry.

Description

technical field [0001] The invention relates to the field of wrenches, in particular to a portable multifunctional wrench with wide application range and comprehensive functions. Background technique [0002] A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. [0003] Existing wrenches mostly only have one or two nuts for screwing threaded fasteners such as bolts, screws, and nuts, and can only be used for one to two types of threaded fasteners such as bolts, screws, and nuts. Modern mechanical equipment often includes threaded fasteners such as bolts, screws, and nuts of many types. When repairing such equipment, multiple wrenches are often required, which is inconvenient to carry and use. [0004] In view of this problem, some multifunctional wrenches have appeared on the market now. These multifunctional wrenches...

Problems solved by technology

[0003] Existing wrenches mostly only have one or two nuts for screwing threaded fasteners such as bolts, screws, and nuts, and can only be used for one to two types of threaded fasteners such as bolts, screws, and nuts. Mechanical equipment often includes many types of threaded fasteners such as bolts, screws, nuts, etc. When repairing such equipment, it is often necessary to use a variety of wrenches, which are inconvenient to carry and use

[0004] In response to this problem, some multi-functional wrenches have appeared on the market. These multi-functional wrenches are equipped with nuts with relatively complete models and comprehensive functions. However, due to the large number of nuts, it is very inconvenient to carry

Especially in some specific fields, the types of nuts that need to be used are also relatively fixed, only a few commonly used ones, resulting in many types of nuts of this type of multifunctional wrench being idle, resulting in a waste of resources
