An inner hexagon telescopic adjustable wrench

Abstract

The invention relates to an internal hexagonal stretching movable wrench, and belongs to the technical field of detachable tools. The internal hexagonal stretching movable wrench comprises an M4 internal hexagonal wrench, an M6 internal hexagonal wrench, an M8 internal hexagonal wrench, an M10 internal hexagonal wrench and an M12 internal hexagonal wrench, wherein the M10 internal hexagonal wrenchis installed in the M12 internal hexagonal wrench, the M8 internal hexagonal wrench is installed in the M10 internal hexagonal wrench, the M6 internal hexagonal wrench is installed in the M8 internalhexagonal wrench, the M4 internal hexagonal wrench is installed in the M6 internal hexagonal wrench, a sealing block is installed at the tail of the M12 internal hexagonal wrench, and a handle is installed at the tail of the sealing block. According to the internal hexagonal stretching movable wrench, the internal hexagonal wrenches which are different in specification are sorted according to thesizes, and the problems that the internal hexagonal wrenches are various in specification, inconvenient to carry and troublesome in use are solved through the stretching design.

Description

technical field [0001] The invention relates to an inner hexagon telescopic adjustable wrench, which belongs to the technical field of dismantling tools. Background technique [0002] At present, the tightening or loosening of the hexagon socket bolts uses fixed hexagon wrenches. Since each specification of the hexagon socket bolts must be equipped with a fixed wrench of the corresponding specification, there are many specifications of the hexagon socket wrench, which is not conducive to storage. And there is the shortcoming of troublesome use, some machines and equipments, the nut that is furnished is various, and the wrench that needs dismantling also is to use in a complete set, needs to replace back and forth, brings great inconvenience to dismounting personnel, and work efficiency is lower. [0003] The patent application number is 201510598744.2 discloses an adjustable internal and external hex wrench, which includes internal fixed pliers and internal movable pliers. T...

Problems solved by technology

[0002] At present, the tightening or loosening of the hexagon socket bolts uses fixed hexagon wrenches. Since each specification of the hexagon socket bolts must be equipped with a fixed wrench of the corresponding specification, there are many specifications of the hexagon socket wrench, which is not conducive to storage. And there is the disadvantage of troublesome use. Some machines and equipment are equipped with various nuts, and the required disassembly wrench is also used in a set, which needs to be replaced back and forth, which brings great inconvenience to the disassembly personnel and low work efficiency.

[0003] The patent application number is 201510598744.2 discloses an adjustable internal and external hex wrench, which includes internal fixed pliers and internal movable pliers. The internal fixed pliers have an inverted V-shaped protrusion with an included angle of 120 degrees. It is an inverted V-shaped protrusion 2 with 120 degrees. The inverted V-shaped protrusion 1 and the inverted V-shaped protrusion 2 protrude toward the direction away from each other, and the diagonals of the two are collinear; it can be adjusted by turning the screw The distance between the inner fixed pliers and the inner movable pliers, because the present invention is through fixing a pair of opposite angles in the inner hexagonal screws, when screwing the larger size inner hexagonal screws or the inner fixed pliers and the inner movable pliers and the inner If the contact surface of the hexagon screw is too small, it will cause the hexagon socket screw to slip. When the surface area of ​​the inner fixed pliers and the inner movable pliers is too large, it cannot be put into the inner hexagon hole of the small size hexagon socket screw, which will lead to the inability to disassemble.
