Abstract
The invention relates to ratchet wrench. It includes handle and sleeve. Its feature is that the handle is formed by upper and lower covers; and the lower one is set one flute to lay the sleeve. Compared with the existing technique, the advantages of the invention are that the upper and lower covers are designed by composite type; it only needs to open the upper cover while taking and putting the sleeve; it can save wrench working time; the processing the upper and lower cover is simple; the production cost is low.
Description
Technical field
The present invention relates to a kind of spanner, relate in particular to a kind of sleeve and can shirk and can deposit in ratchet spanner in the handle.
Background technology
Hand-operated tools all plays a part to promote the productivity progress in each society, because the invention and the application of screw, screw bolt and nut make spanner become a kind of very important instrument in the mechanical hand-operated tools field.Since the spanner invention various spanners have appearred so far, as combination wrench, open-end wrench, ring spanner, ratchet wrench or the like.
In the box spanner technical field, because nut or screw are different at the size dimension of different its uses of occasion, make the sleeve be used to drive these nuts or screw also require different internal diameters to cooperate with it, a kind of tool box has so just appearred, its inside is placed with a ratchet wrench, also be placed with the sleeve of a series of different inner diameters sizes simultaneously, these sleeves can realize that detached type combines with box spanner, come nut or screw at different model thus.It is excessive to imagine that this design tool takies volume, carry and transport also inconvenience, and production cost is also higher.
U.S. Pat 4253356 discloses a kind of ratchet wrench, handle hollow in this spanner structure, and the sleeve of different inner diameters is located in the handle successively along the handle axis direction, and expose, though it is more convenient that this kind design sleeve picks and places, wrench operated gets up extremely inconvenient; US4627315 discloses a kind of box socket set again, handle hollow in this spanner structure, end has mouth, sleeve is positioned in the hollow handle perpendicular to handle axis direction drawing and pulling type, the handle portion width is bigger, the overall structure comparison clumsiness that seems, operation also is not very convenient, US6401577B1 and US6349623B1 all disclose a kind of ratchet wrench again, with respect to the former patent, its difference is that sleeve is parallel to handle axis direction drawing and pulling type and is positioned in the hollow handle, US4627315 is the same with patent, the dish (trap) of taking out that is used to place sleeve by pull is realized picking and placeing of sleeve, takes out to be useful on the structure of separating the sleeve placement space on the dish (trap), and the overall volume of spanner has had bigger reduction, but pick and place sleeve at every turn and all will move whole row's sleeve, still quick inadequately in the operation, and handle portion hollow design and take out dish (trap) and concerning the workman produces, have difficulty, production cost is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide at the above-mentioned state of the art that a kind of volume is little, sleeve picks and places ratchet spanner efficiently.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this ratchet spanner, comprise that handle and dismountable type be located at the sleeve of handle head, described handle is made up of loam cake and the lower cover that cooperates with the loam cake dismountable type, be provided with the groove that to place at least one sleeve in the described lower cover, this spanner also comprises the bonnet of being located at handle end, it is characterized in that being provided with in the described bonnet magnet that is used for the magnetic sleeve, be provided with a magnet that is used for the magnetic sleeve in the described bonnet, be convenient to picking and placeing of sleeve.
Loam cake and lower cover dismountable type fit structure can be provided with in the following way: described loam cake is provided with an extension near the handle head, accordingly, the described button portion that cooperates snapping with described extension that is covered with down, described loam cake afterbody is provided with joint portion on, described lower cover afterbody also is provided with joint portion, and described bonnet is connected loam cake and lower cover by the described joint portion of going up with the combination of following joint portion.Also can adopt and renovate in the prior art or the slip lid mode substitutes, but be preferred in the above described manner.
The corresponding described joint portion of going up of described bonnet is provided with a holddown spring with following joint portion, is used for fixing magnet.
As preferably, described go up the joint portion or/and down the outer wall of joint portion be provided with convex tendon, accordingly, described bonnet inwall is provided with the inner convex rib that cooperates with described convex tendon.Also can adopt screw connection structure.
As improvement, the described joint portion of going up is first annulus, and described joint portion down is one to cooperate second annulus of forming an annulus with last joint portion.
Be provided with the demarcation strip perpendicular to groove in the described groove, demarcation strip and groove inwall surround the admittance chamber that is fit to place sleeve, and different sleeves can be placed in the corresponding admittance chamber.This kind design increases ratchet spanner tensile strength.
The indoor keeper that is provided with abutment sleeve of described admittance, it is comparatively fixing to make that sleeve is placed in the admittance chamber.
As improvement, described admittance chamber increases to afterbody successively from the handle head, and the indoor sleeve vertical handle axis direction of described admittance is placed.
Compared with prior art, the invention has the advantages that: adopt the loam cake and the design of lower cover combined type of split, open loam cake as long as pick and place sleeve, it is fast convenient more to pick and place, and has saved the working time of spanner, simultaneously, the production and processing of loam cake and lower cover is also simple and convenient, and production cost is lower; Be positioned at the stand-by sleeve of magnet magnetic of bonnet, need not point stingy sleeve like this, just light and handy the taking out of energy of sleeve puts in and also can so operate, and is more convenient for picking and placeing of sleeve; Whole simultaneously volume does not increase the structural design advantages of simple.
