Abstract

The utility model discloses a four-purpose movable spanner which is used for assembling and dismounting the bolts and the nuts of an opening surface, particularly the bolts and the nuts of a narrow surface or a concave surface, and an inner hexagonal bolt fastener with a cylinder head. Because a ratchet mechanism with a square coupler is arranged on the spanner jaw of the head of a universal movable spanner, the spanner is connected with the ratchet mechanism by an extension bar, a collet head, and an outer hexagon head to achieve the functions of the movable spanner, a ratchet spanner, a socket spanner, and an inner hexagon spanner, and operate the bolts and the nuts of the opening surface, the narrow surface, and the concave surface, and the inner hexagonal bolt fastener with the cylinder head.

Description

Four-purpose movable spanner

The utility model is used to out face, especially for narrow, and the bolt on the concave surface, the Assembly And Disassembly of nut and socket cap hexagon socket head cap screw securing member.

Industrial and agricultural machinery is produced, and be unable to do without spanner in the assembling process, especially needs conversion wrench opening size often, all uses adjustable wrench.Because the adjustable wrench head dimensions is bigger, when narrow and small or recessed darker bolt, nut or socket cap hexagon socket head cap screw, it is powerless that adjustable wrench just seems in the turn status.Often to use ratchet spanner, box spanner or inner hexagon spanner instead.And the adjustable wrench of simple function uses many inconvenience also arranged, or even infeasible.

The purpose of this utility model is that a kind of improved adjustable wrench will be provided, and it can be operated effectively to bolt and nut and socket cap hexagon socket head cap screw on narrow, concave surface.

The purpose of this utility model is achieved in that at general adjustable wrench head pulls a mouthful full-size position, loads onto a ratchet mechanism.Two square joints are arranged in this mechanism, and it can have square hole joint, an end to have the extension bar of square joint to join with an end.The square joint end of extension bar can join with the collet head of different size again, and when the general universal screw wrench of turn, collet head just can be realized narrow, the bolt on the concave surface, the operation of nut.If the straight joint of an elder generation of the square joint on the ratchet mechanism and a band square hole joins, this straight joint joins with the outer-hexagonal head that an end has a square joint different size again, when the general universal screw wrench of turn, the outer-hexagonal head just can be realized the operation to the socket cap hexagon socket head cap screw.

The utility model is because be to load onto a ratchet mechanism simple in structure at general universal screw wrench head plate mouth place, square joint above it can with the band square hole straight joint, the outer-hexagonal head of band square joint or general part extension bar, collet head join, enlarged the use model of general universal screw wrench, realized operation bolt, nut and socket cap hexagon socket head cap screw on narrow, concave surface.No matter owing to be that collet head or outer-hexagonal head all are to be connected on the ratchet mechanism, so can the sour jujube lemon to their operation.This wrench has the function of universal screw wrench, ratchet wrench, impact wrench, Allen wrench.Simultaneously,, make and select for use all easily, be easy to realize because the part modular construction that increased is simple or general utility tool, general part.

Describe the detail and the working condition of the utility model wrench in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7.

This wrench comprises a general universal screw wrench of main body＜1 〉, locating at its head plate mouth＜2〉can be ratchet mechanism＜3〉top loading that has mounting groove＜4〉and＜18 〉, ratchet＜12〉is contained in the hole＜16〉of ratchet mechanism body＜5 〉, the aperture 14 to 26mm.Have symmetrical holes＜6〉and＜10〉on the body＜5 〉, the aperture 6 to 8mm, the center line of hole＜6 〉,＜10〉and hole＜16〉are tangent, hole＜6 〉, spring＜9 〉,＜15〉are housed＜10〉and have orientation axes＜7 〉,＜11〉of tooth＜8 〉,＜14 〉, on the tooth＜13〉that often leans against ratchet＜12〉in the tooth＜8〉on the orientation axes under the pressure of spring＜9 〉,＜15 〉,＜14 〉, 20 of the ratchet numbers of teeth are for well, positive profile of tooth, the profile of tooth angle is preferably in 110～120 °.Ratchet＜12〉is when changeing counterclockwise, tooth on the ratchet and the engagement of the tooth on the orientation axes, ratchet is directed axle＜7 〉,＜11〉locked, when clockwise rotating, toothed orientation axes＜7 〉,＜11〉promoted by ratchet, ratchet is free to rotate, ratchet＜12〉external part has two square knuckle＜17 〉, it can have square hole joint＜22〉one ends to have the thick stick that connects of square joint＜23〉to join with an end, the square joint＜23〉that connects thick stick＜21〉can join with the square hole joint＜25〉on the collet head＜24〉of different size again, the general universal screw wrench of turn＜1 〉, collet head＜24〉just can be to narrow, bolt on the concave surface, nut is operated.If the square knuckle of ratchet external part＜17〉is joined with the straight joint＜19〉of band square hole＜20〉earlier, the straight joint other end joins with the outer-hexagonal head＜26〉that an end has square joint＜a 27〉different size again.During the general monkey spanner of turn＜1 〉, outer-hexagonal head＜26〉just can be realized the operation to the socket cap hexagon socket head cap screw.Because all by the ratchet mechanism carry-over moment, operating process can be twisted by sour jujube.
