Abstract

The invention discloses an internal hexagonal wrench, and belongs to a maintenance tool. The internal hexagonal wrench structurally comprises a wrench body and a wrench head, wherein the upper end of the wrench body is provided with a groove corresponding to the wrench head, the wrench head consists of a spring and a plurality of internal hexagonal wrench heads with different models, the interior of the outmost wrench head is hollow, the back end of the hollow cavity is sealed and connected with the spring, the other end of the spring is connected with a top plate, the other side of the top plate is used for supporting other internal hexagonal wrench heads, except for the outmost wrench head, the internal hexagonal wrench heads are sequentially and coaxially sheathed together according to the sizes and the models, the side wall of the middle part of the wrench body is provided with a switch and an LED (light emitting diode) switch, and the interior of the cavity at the tail end of the wrench body is fixedly connected with a bolt opening cleaner by a back end cover. The internal hexagonal wrench has the advantages that a bolt opening can be cleaned, the different sizes and models of bolts can be tightened and loosened, and the wrench can normally work at dark or under the condition of sudden power failure.

Description

A kind of inner hexagon spanner

Technical field

The present invention relates to a kind of maintenance tool, especially a kind of inner hexagon spanner.

Background technology

In recent years, hexagon socket head cap screw be more and more used in people life and in producing, but sometimes also bring many puzzlements to maintainer.Some hexagon socket head cap screws are covered with dust for a long time on machine, and its bolt mouth has fallen to expiring dust or part is got rusty, and makes workmen cannot directly send tight operation to bolt; Some hexagon socket head cap screws are disposed in the dark portion of machine, or when darkness, cannot carry out operation because staff does not see the position of bolt; And the spanner of existing fastening hexagon socket head cap screw is all independent hexagonal prism, namely the spanner that the hexagon socket head cap screw of each model is corresponding different respectively, therefore, workman needs the inner hexagon spanner carrying multiple different size specification comprehensively to overhaul lathe and instrument, thus causing the operating time of workman long, labour intensity is large.

Summary of the invention

Technical assignment of the present invention provides a kind of inner hexagon spanner for above-mentioned deficiency of the prior art, this functions of wrench can be various, can clean bolt mouth, degree of tightness operation can be carried out again for the bolt of multiple different size size, simultaneously at darkness weather or when having a power failure suddenly, also can as usual work.There is the features such as multiple functional, easy to use.

The technical solution adopted for the present invention to solve the technical problems is: a kind of inner hexagon spanner, and described driving end is made up of the internal hexagonal wrench head of spring and multiple different model; Outermost driving end inner hollow, described hollow chamber back-end closure is also connected with spring, the other end of described spring is connected with top board, the opposite side of described top board is supported with all the other internal hexagonal wrench heads except large size driving end, and the outer wall of all the other internal hexagonal wrench heads is equipped with the step of evagination; Except the inside driving end, other internal hexagonal wrench heads all have and kiss the through hole of joining with the internal hexagonal wrench head outer wall of adjacent inner, and multiple driving end by size model successively coaxial sleeve connect together;

Spanner upper end offers the groove corresponding to driving end, and namely spanner and driving end are for removably connecting, and are convenient for carrying.

In the middle part of spanner, sidewall is provided with switch and LED, is provided with button cell in sidewall, and switch and LED and button cell form a closed-loop path by wire;

Described spanner tail end extending direction offers a cavity, and cavity external screw thread connects a rear end cap, and rear end cap inner surface is connected with bolt mouth cleaner.

Multifunction cup of the present invention compared to the prior art, there is following outstanding beneficial effect: this functions of wrench can be various, can clean bolt mouth, degree of tightness operation can be carried out again for the bolt of multiple different size size, simultaneously at darkness weather or when having a power failure suddenly, also can as usual work.There is the features such as multiple functional, easy to use.

Detailed description of the invention

With reference to Figure of description, inner hexagon spanner of the present invention is described in detail below.

A kind of inner hexagon spanner, comprise spanner 1 and driving end 2, spanner 1 upper end offers the groove 8 corresponding to driving end; Described driving end is made up of the internal hexagonal wrench head of spring 3 and multiple different model; Outermost driving end 4 inner hollow, described hollow chamber back-end closure is also connected with spring 3, the other end of described spring is connected with top board 5, the opposite side of described top board is supported with all the other internal hexagonal wrench heads except the driving end of outside, and all the other internal hexagonal wrench head outer walls are equipped with the step of evagination; Except the inside driving end 6, other inner hexagon spanners all have and kiss the through hole 7 of joining with the internal hexagonal wrench head outer wall of adjacent inner, and multiple driving end by size model successively coaxial sleeve connect together;

In the middle part of spanner, sidewall is provided with switch and LED 9, is provided with battery 10 in the chamber of interior.When not seeing the position of bolt in darkness or when having a power failure suddenly at work, can open LED, switch and LED and button cell form a closed-loop path by wire, thus make staff as usual carry out operation.

Its tail end of described spanner offers a cavity 11, and cavity internal thread connects a rear end cap 12, and rear end cap inner surface is connected with bolt mouth cleaner 13.

Further, described bolt mouth cleaner is by shovel 14, forms with the spade 15 of bristle 16 and the spanner rear end lid that is connected with spade.

In mechanical disorder maintenance process, some hexagon socket head cap screws are covered with dust for a long time on machine, its bolt mouth 17 has fallen to expiring dust or part is got rusty, now, can to back-out rear end cap, to extract bolt mouth cleaner out, with its shovel head the dust in bolt mouth 17 or spot be dug and pluck out, then with bristle, bolt oral thermometer face is cleaned, finally utilize the driving end of inner hexagon spanner appropriate size model to carry out degree of tightness operation to respective bolt.

This invention inner hexagon spanner has the features such as multiple functional, easy to use, except the technical characteristic described in description, is the known technology of those skilled in the art.
