Description

HEXAGON KEY WRENCH COMBINATION SHEATH

FIELD OF THE INVENTION

The present invention relates to a toolbox for containing hexagon key wrenches, and more particularly to a simple-structured toolbox capable of simultaneously containing several hexagon key wrenches of different sizes and

specifications.

BACKGROUND OF THE INVENTION

Referring to FIG 1, a prior art hexagon key wrench

combination sheath includes a rectangular plastic plate body 1, and the front side of the plate body 1 has an externally protruding first inserting body 2, and the first inserting body 2 at its axial direction has a circular inserting hole 4 penetrating both ends of the first inserting body 2, and a second inserting body 3 is disposed at the front of the first inserting body 2, and the first inserting body 2 and the second inserting body 3 have different heights to constitute a stairway-shape positional difference, and the second inserting body 3 at its axial direction has a plurality of circular inserting holes 4, and the plurality of circular inserting holes 4 is provided for inserting hexagon key wrenches of different diameters, and the plate body 1 at its top has a hanging hole 5, and the hanging hole 5 facilitates hanging the hexagon key wrench combination sheath on a hook (which is not shown in the figure). However, the prior art hexagon key wrench combination sheath can only provide the function of hanging a small quantity of hexagon key wrenches. If there are two types of hexagon key wrenches of metric and British systems, then it will need another hexagon key wrench combination sheath, which will occupy much space. As we all know, the hexagon key wrenches come with a metric system or a British system, or an even number or an odd number for the installation. When the hexagon key wrench is used for turning a screw, it is necessary to leverage a handle for the turning function, which is inconvenient for its use.

Furthermore, the prior art hexagon key wrench combination sheath is manufactured according to the diameter and size of each circular inserting hole 4, which requires several molds, and thus increasing the manufacturing cost.

In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the sales and marketing of similar products to conduct extensive researches and experiments, and finally invented a very useful hexagon key wrench combination sheath to overcome the shortcomings of the

prior art hexagon key wrench combination sheath.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a hexagon key wrench combination sheath that comprises a first latching element and a second latching element which are pivotally coupled and hollow, and the open ends of the first and second latching elements include a plurality of concave edges corresponding to different hole diameters, and the two corresponding concave edges are engaged to form an inserting hole, and the inserting hole can clamp a hexagon key wrench, and a short shaft section of the hexagon key wrench can be inserted into a sheathing hole of the second latching element. A casing can be latched onto the latching elements, and the casing at its left and right sides respectively includes a latching portion for fixing a sheath, and the sheath along its longitudinal direction has holes of different diameters for inserting a plurality of different sized hexagon key wrenches, so as to contain hexagon key wrenches of different specifications, and the first and second latching elements are provided for movably opening and clamping hexagon key wrenches of various model numbers for securing or loosening a screw and complying with the ergonomic way of applying forces by human hands.

Another objective of the present invention is to provide a hexagon key wrench combination sheath, and the casing can be latched by different sheathes with different sized holes, so that users can select the desired sheath for use. If the first and second latching elements are not in use, the casing can be latched onto the first and second latching elements, and the sheath can be embedded into both sides of the casing, so as to reduce the volume for easy carrying and storage.
