Description

Dual-purpose combined wrench

Technical Field

The utility model relates to an oxygen ethane opens valve technical field, especially relates to a dual-purpose combination spanner.

Background

The wrench is a common mounting and dismounting tool, and is a manual tool for screwing bolts, screws, nuts and other threads to tightly hold open or trepanning fasteners of the bolts or nuts by utilizing the lever principle. The wrench is typically made of structural steel of carbon or alloy material. The wrench is generally provided with an opening or a trepanning for clamping a bolt or a nut at one end or two ends of a handle part, when the wrench is used, the bolt or the nut can be screwed by applying external force to the handle part along the rotation direction of a thread, and the wrench is basically divided into two types, namely a dead wrench and an adjustable wrench. The former refers to a wrench with fixed digital writing, and the latter is an adjustable wrench. The solid wrench has one or two ends with fixed size opening for screwing certain size nut or bolt. The double offset ring spanner has two working ends with hexagonal holes or dodecagonal holes at two ends, and is suitable for occasions with narrow working space and where ordinary spanners cannot be used. The dual-purpose wrench has one end identical to that of the single solid wrench and the other end identical to that of the double offset ring spanner, and bolts or nuts of the same specification are screwed at the two ends. The width of the opening of the adjustable wrench can be adjusted within a certain size range, and bolts or nuts with different specifications can be screwed. The structure of the wrench is characterized in that a fixed jaw is made into a flat jaw with fine teeth; one end of the movable jaw is made into a flat jaw; the other end is made into a concave jaw with fine teeth; the worm is pressed downwards, the movable jaw can be quickly taken down, and the position of the jaw is changed. The hook-shaped wrench is also called crescent wrench and is used for screwing flat nuts with limited thickness. The socket spanner consists of several sockets with hexagonal or dodecagonal holes and several accessories, including handle, connecting rod, etc. and is especially suitable for screwing bolt or nut in very narrow or deep recess. The inner hexagonal wrench is an L-shaped hexagonal rod-shaped wrench and is specially used for screwing an inner hexagonal screw. A torque wrench which can display the applied torque when a bolt or a nut is screwed; or a light or audible signal may be emitted when the applied torque reaches a specified value.

The existing market has a common adjustable wrench and an internal square ethylene bottle valve opening tool, which can be used for opening oxygen and ethylene bottles, but the tools are independent and need to be carried separately during working. Because the valve opening tool of the inner square ethylene bottle is small and easy to lose, the ethylene bottle cannot be opened after the valve opening tool is lost, and a dual-purpose combined wrench is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems that the prior adjustable wrench and the valve opening tool for the inner square ethylene bottle in the market can be used for opening the valve for oxygen and ethylene bottles, but the tool is independent and needs to be carried respectively during working.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a dual-purpose combination wrench, includes spanner control portion, surface fixedly connected with spanner afterbody behind the spanner control portion, hexagonal subassembly in the surface fixedly connected with under the spanner afterbody, surface fixedly connected with spanner head before the spanner control portion, outer hexagonal groove has been seted up to spanner head front surface, the inner caulking groove has been seted up to spanner head upper surface, the mounting groove has been seted up to spanner head lower surface, the supporting interior cubic subassembly that is provided with of mounting groove, the supporting fastening bolt that is provided with of inner caulking groove.

Preferably, the cross section of the wrench control part is in an isosceles trapezoid shape, the cross section of the tail part of the wrench is in a key shape, and the cross section of the head part of the wrench is in an arc shape.

Preferably, the outer surface of the inner hexagonal component is in a regular hexagon arrangement.

Preferably, the mounting groove and the embedded groove are located on the same vertical surface.

Preferably, the position of the outer surface of the inner square component, which is close to the top, is in inserted connection with the inner surface of the mounting groove, and the fastening bolt is embedded in the embedded groove.

Preferably, an internal thread hole is formed in the inner surface of the inner square component and is in threaded connection with the outer surface of the fastening bolt.

Compared with the prior art, the utility model has the advantages and positive effects that,

the combined wrench can be used for opening and closing oxygen and ethylene bottles and fastening screws. The combined wrench is easy to find and patrol and not easy to lose due to the obvious relative volume.
