Abstract
The utility model relates to a hanging clamp for a ratchet spanner, belonging to the technical field of tool accessories. The hanging clamp is used for suspending the ratchet spanner by inserting a square tenon of the ratchet spanner and is provided with a plate-type main body; the plate-type main body is machined with a lantern ring for inserting of the square tenon; the internal ring of the cross section of the lantern ring is circular; the side wall of the lantern ring is provided with a slot; when the square tenon is inserted into the lantern ring and the ratchet spanner is rotated forward, the lantern ring is used for clamping the square tenon and a ratchet wheel of the ratchet spanner to rotate oppositely; when the square tenon is inserted into the lantern ring and the ratchet spanner is rotated reversely, the ratchet spanner is used for driving square tenon and the lantern ring to rotate reversely. According to the hanging clamp disclosed by the utility model, the elastic lantern ring forms intermediate clamping force to the square tenon and can be used for clamping the square tenon without rotation when the whole ratchet spanner is rotated forward; when the whole ratchet spanner is rotated reversely, the square tenon is driven to overcome the clamping force and rotate reversely along with the whole ratchet spanner; thereby, the inspection of the hanging clamp with very simple structure and low cost to the rotation quality of the ratchet spanner arranged on the hanging clamp is realized.
Description
Technical field
The utility model relates to a kind of ratchet spanner with hanging tag, and belongs to the attachment technical field.
Background technology
In the traditional emporium,, mainly be to pack or the exhibition method of other fixing and packagings for the sale of ratchet spanner; When buying, can not packing be opened inspection or on probation, sell in order to avoid influence secondary, the buyer is only buying product; After actual the use; Can find just whether product exists quality problems,, influence consumer's right so can produce a series of contingency questions of return of goods and so on.
To above-mentioned defective, occurred hanging ratchet spanner at present and carried out sale with hanging tag.But the user before formal purchase ratchet spanner, need know the quality of (check) ratchet spanner usually.The method of check ratchet spanner is through forward and reverse rotating ratchet spanner, tests the quality of judging reversible ratcheting tool.Understand according to the applicant, the existing ratchet spanner that hangs tag suspension mostly can't directly be tested its quality through forward and reverse rotating ratchet spanner.
Through retrieval; Application number is that 200920191349.2 Chinese patent has announced that a kind of packing of product hangs tag; It is through being provided with runner on the link plate, the head of ratchet spanner is inserted in the runner to be rotating with it be connected, and can check the ratchet spanner quality through runner.But the complex structure that this packing hangs tag.
In addition; The applicant is that 201120086448.1 Chinese patent discloses a kind of ratchet spanner with hanging tag at the application number of first to file; This hangs tag and drives ratchet spanner through a pair of ratchet fit structure that forms at its end face and rotate and check the ratchet spanner quality; But this end face ratchet fit structure structure or more complicated, and cost is high, fragile.
Summary of the invention
The technical problem that the utility model will solve is, and is not enough to prior art, proposes a kind of can when purchase, test to ratchet spanner easily and simple in structure, cost is low hangs tag.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of ratchet spanner is with hanging tag; Be used for hanging ratchet spanner through the square tenon of plug-in mounting ratchet spanner; It has a plate-like body; Be shaped on the collar that is used for the said side's tenon of plug-in mounting on the said plate-like body, the interior ring cross-section of the said collar is round, has the line of rabbet joint on the sidewall of the said collar; When said side's tenon inserts the collar and makes the ratchet spanner forward rotation; The ratchet of the said collar side's of clamping tenon and ratchet spanner relatively rotates; When said side's tenon inserted the collar and makes the ratchet spanner backward rotation, the said ratchet spanner side's of the drive tenon and the said collar relatively rotated.
Generally, when ratchet spanner integral body forward rotation, the whole backward rotation of the relative ratchet spanner of the square tenon of ratchet and plug-in mounting; And when ratchet spanner integral body backward rotation, ratchet is not rotated relative to spanner integral body with square tenon by the ratchet resistance limits, thereby along with counter-rotational ratchet spanner integral body backward rotation together.The present invention has designed elastic collar dexterously on the body of ratchet spanner; Coming the other side's tenon to form the little clamping force of a strength with this elastic collar (is frictional force; Four angle ends of side's tenon can form suitable frictional force with the circular inner wall of elastic collar, and the frictional force when the angle end of especially square tenon drops on the line of rabbet joint place of elastic collar inwall is bigger).This clamping force can make the collar side of clamping tenon not rotate when ratchet spanner integral body forward rotation, thereby makes the whole backward rotation of the relative ratchet spanner with square tenon of ratchet; And in ratchet spanner integral body backward rotation the time; Side's tenon can overcome this clamping force (moment when promptly this clamping force is less than ratchet spanner integral body backward rotation) again; Thereby the side's of making tenon is along with ratchet spanner integral body backward rotation together; At this moment, square tenon relatively rotates (being collar the other side's tenon forward rotation mutually) with the collar.That brings like this invention has the beneficial effects as follows: very simple and low the hanging tag of cost realized being located at the check that ratchet spanner on hanging tag rotates quality with structure.
The supplementary notes of technique scheme are: when said side's tenon inserts the collar and makes the ratchet spanner backward rotation, and the moment of the clamping force between the said collar and the square tenon during less than the ratchet spanner backward rotation.
The improvement one of technique scheme is: the inwall side face of the said collar is the face of cylinder.
The improvement two of technique scheme is: the inwall of the said collar is formed with tapering.
The further improvement one of technique scheme is: the inwall of the said collar is formed with single tapering, and the inwall side face of the said collar is the circular cone table top.
The further improvement two of technique scheme is: the inwall of the said collar is formed with double tapered, and the inwall side face of the said collar is two relative circular cone table tops in minor axis top each other.
The perfect of technique scheme is: an end of the said collar is shaped on chamfering.
Improving of technique scheme one is: the said line of rabbet joint is to be two of word symmetry around collar kernel of section.
Improving of technique scheme two is: the said line of rabbet joint is to be four of cross symmetry around collar kernel of section.
Further improving of technique scheme is: said plate-like body bottom fastens has grooved antitheft washer.
Further improving again of technique scheme is: be positioned at collar both sides on the said plate-like body and be shaped on the catching groove that is used for eye-splice antitheft washer.
