Description
Technical field
The utility model relates to a kind of spanner, belongs to hardware & tools technical field.
Background technology
Spanner is a kind of conventional installation and removal instrument.Lever principle is utilized to twist the securing member such as bolt, screw and nut, but often limited in small space.Such as when kitchen faucet, bathroom faucet and toilet seat water part install or remove, when changing corresponding flexible pipe, because operating space is narrow, the operation of common wrench is restricted, operation inconvenience.
In order to twist bolt or the nut of the very narrow and small or very depths of caving in, space, there is box spanner.Box spanner generally by multiple different size sleeve and be furnished with the multiple accessories such as handle, extension bar and form.Described sleeve is generally columnar structured, band hexagonal or 12 jiaos of trepannings, but external diameter and length etc. design for application scenario, and country does not have Uniform provisions.The opening of current known spanner or the specification seriation of trepanning, express with the distance of opposite side, unit is mm.
Existing box spanner, when installing kitchen faucet, bathroom faucet and toilet seat water part, can avoid the restriction of small space, really effectively; But when changing the flexible pipe of kitchen faucet, bathroom faucet and toilet seat water part, the trepanning due to box spanner is closed, cannot through the flexible pipe connected, therefore helpless.Common fork spanner or the opening of shfting wrench can pass, but limit by small space, operation inconvenience.
In order to the trepanning solving existing box spanner is closed, cannot pass pipeline, existing open-end wrench, in the problem of small space limitation of activity, the utility model proposes a kind of open sleeve spanner for small space.
Summary of the invention
The purpose of this utility model is to provide a kind of open sleeve spanner for small space, can pass pipeline, can be used in again narrow space or the dismounting of the very depths of caving in or installation exercise.
A kind of open sleeve spanner for small space comprises main spanner 1, secondary spanner 2 and connecting axle 3, as shown in Figure 1.The pommel band of described main spanner 1 is fluted, and the pommel of secondary spanner 2 is with tenon, hinged by connecting axle 3, can relatively rotate, and can pass pipeline, for dismounting or the installation exercise of narrow space or the very depths of caving in.
Described main spanner 1 comprises main driving end 11, master collet 12 and main spanner handle 13, hinged by connecting axle 3 and secondary spanner 2, is connected and clamps, carry out dismounting operation with the bolt or nut wanting dismounting, is used as crank handle, to increase the arm of force when secondary spanner 2 operation.The described arm of force refers to the distance of stress point and pivot; Increase the arm of force, can moment be increased, more laborsaving, reduce task difficulty.Described main driving end 11, with opening, is connected with the bolt or nut wanting dismounting and clamps, carrying out dismounting operation.Described master collet 12 is cylinder-like structure, and one end and main driving end 11 are rigidly connected, and opens axial groove at the circumferential position corresponding to main driving end 11, and the other end and main spanner handle 13 are rigidly connected, and makes winner's spanner 1 become the entirety of a rigidity.The opposite side distance that the width of described axial groove is not less than main driving end 11 opening from so that through pipeline, make the utility model can install and remove nut on pipeline.Described main spanner handle 13 is with fluted, by groove and secondary spanner 2 hinged, in the center of groove two side, with through hole, and coordinated with connecting axle 3 by described through hole.
Described secondary spanner 2 comprises secondary driving end 21, secondary case cylinder 22 and secondary spanner handle 23, is connected and clamps, carry out dismounting operation with the bolt or nut wanting dismounting, hinged by connecting axle 3 and main spanner 1, and relatively rotate, be used as crank handle when main spanner 1 operation, to increase the arm of force.Described secondary driving end 21 is identical with the 26S Proteasome Structure and Function of main driving end 11, and specification is different, can install and remove nut or the bolt of different size.Described secondary case cylinder 22 is identical with the 26S Proteasome Structure and Function of master collet 12, is rigidly connected with secondary driving end 21 and secondary spanner handle 23, makes secondary spanner 2 become the entirety of a rigidity.Described secondary spanner handle 23 with tenon, by tenon and main spanner 1 hinged, in the center of tenon side with through hole, and by described through hole and connecting axle 3 matched in clearance.
The preferred known cross dormant bolt of described connecting axle 3 or tack pin axle, be connected with main spanner 1 and secondary spanner 2 respectively, makes winner's spanner 1 and secondary spanner 2 hinged.
The beneficial effects of the utility model are: the utility model can pass pipeline, to install and remove the nut on pipeline; Can be used in again narrow space or the dismounting operation of cave in very depths nut or bolt; Solve known box spanner trepanning to close, cannot pass pipeline, cannot install and remove the nut on pipeline, known open-end wrench is in the technical problem of small space limitation of activity.The utility model comprises mutually hinged main spanner 1 and secondary spanner 2; If the operation of main spanner 1, secondary spanner 2 is as crank handle; If the operation of secondary spanner 2, main spanner 1 is as crank handle; Increase the scope of application of the present utility model, efficiently easy to operate.
