Description

A kind of twin adapter box socket set

Technical field

The utility model relates to assembly tool technical field more particularly to a kind of twin adapter box socket sets.

Background technique

In our actual lives, there are a kind of ratchet spanneres, its main feature is that head has a ratchet device can be by putting To control spanner only to the left or only to the right, this normal mating sleeve of ratchet spanner uses plectrum outside, is locked fastener simultaneously Plectrum is adjusted, can be rotated along some direction to tighten or loosening fasteners, still, often we when in use, can not differentiate It tightens out or the direction of loosening fasteners, needs to rotate to experience spanner tightening or unclamping direction and then adjust and dial to fastener Piece reuses, and causes inconvenient for use, and structure is complicated, not easy to produce for this plectrum reversing arrangement.

There are also a kind of ratchet spanner, with handle ratchet wheel, i.e., ratchet lines is set inside annulus, within ratchet be arranged tightly It is used after firmware, this ratchet spanner cannot be used for being located at the fastener of depths, not very practical.

Application No. is 201320667915.9 patent documents to disclose such a ratchet spanner, including ratchet spanner master Body, ratchet, lock pin, pin and spring, which is characterized in that the ratchet spanner further includes two grease nipples, and respectively first is yellow Oil nozzle and the second grease nipple have a channel inside two grease nipples, which extends through grease nipple bottom end from grease nipple top, Bottom end is equipped with screw thread, and grease nipple connect with ratchet spanner main body, and the ratchet spanner body interior has a channel, in the channel It is sequentially arranged with spring and lock pin from the inside to surface.Wherein, lock pin one end is side grain, and the other end is scarf, close to flat on lock pin Section one end is provided with pinhole, and the pinhole is for installing pin, and pin is mutually perpendicular to lock pin, the scarf and ratchet of lock pin It offsets, cross section and the spring of lock pin offset.The utility model need when in use by be arranged after fastener rotated with It tightens or loosening fasteners, but it is smooth annulus that the utility model, which is arranged the part of fastener, is easy during rotation Skidding causes inconvenient for use.

Summary of the invention

The utility model will solve the above problems, and provide one kind and fill when having positive and negative two muff joint, using without commutating It sets and changes direction, just can determine that the twin adapter box socket set to the elastic direction of fastener without trial rotation direction.

The technical solution that the utility model solves the problems, such as be to provide a kind of twin adapter box socket set, including handle with And be connected to the disassembly and assembly structure of handle one end, it is characterised in that: the disassembly and assembly structure include the shell with ratchet installation space, Ratchet in the ratchet installation space, the pawl for forcing the ratchet one-way rotation and follow the ratchet wheel Double end connector, the double end connector include for the interconnecting piece fixed with the ratchet and being arranged in the sleeve at interconnecting piece both ends Connector.

Preferably, the disassembly and assembly structure is fixedly connected by shell with the handle；The shell is connect with the handle The through-hole that place is provided with convenient for pawl disengaging.

It preferably, further include casing, the handle is set in described sleeve pipe.

Preferably, the handle is hollow structure, and the pawl is telescopically disposed in the handle by spring.

Preferably, the handle end is provided with the adjusting bolt to adjustment spring elasticity.

The utility model has the beneficial effects that

1. the muff joint at double end connector both ends has respectively represented different ratchet wheel directions, that is, represents spanner and twist Direction that is tight or unclamping, is not necessarily to reversing arrangement, and structure is simple, easy to operate, is readily produced.

2. ratchet is combined with box spanner, ratchet as rotation direction control tool rather than the fastener that is locked Fastening tool not only as box spanner applies in general to dismount the fastener of various positions, but also overcomes box spanner and turns The dynamic indefinite problem in direction.

3. the combination of ratchet, pawl and spring is so that ratchet activity is smooth, is not easy stuck, of simple structure and strong practicability.

Specific embodiment

Specific embodiment of the present utility model below, and in conjunction with attached drawing, to the technical solution of the utility model make into The description of one step, but the utility model is not limited to these examples.

A kind of twin adapter box socket set, as shown in Figure 1, including handle 100 and being connected to tearing open for 100 one end of handle Assembling structure 200.Wherein, the running of the utility model relies primarily on the ratchet 210 in disassembly and assembly structure 200 and connects with ratchet 210 220 components of double end connector connect.Double end connector 220 includes interconnecting piece 221 and the sleeve for being separately mounted to 221 both ends of interconnecting piece Connector 222, interconnecting piece 221 passes through the centre bore of ratchet 210 and is fixedly connected with centre bore, thus by double end connector 220 and spine Wheel 210 connects, and muff joint 222 is made to be distributed in the two sides of ratchet 210.

Ratchet 210 and double end connector 220 are mounted in shell 230, and are connect by shell 230 with handle 100.Such as Fig. 3 Shown, in the present embodiment, handle 100 is the cylindrical body of inner hollow；Shell 230 is that inside offers ratchet installation space 231 Cylindrical body, by by the axially vertical connection of the axial direction of handle 100 and shell 230, thus by handle 100 and disassembly and assembly structure 200 connect, and the junction of handle 100 and shell 230 offers through-hole, so that the hollow inside of handle 100 and shell 230 hollow internal connection communicates.

Ratchet installation space 231 is for disposing ratchet 210 and double end connector 220, therefore, in order to meet ratchet 210 with And the installation requirements of double end connector 220, a bottom surface of shell 230, and be referred to as to accept bottom surface, it is lesser to offer radius Through-hole is only used to pass through muff joint 222, and accepts ratchet 230；230 inner hollow of shell, and the bottom surface of the other end claim Be fixed bottom, offer the biggish through-hole of radius pass through ratchet 210, meanwhile, in order to limit ratchet 210 outside Without dropping out inside shell 230, also need to cover one layer of cover board in fixed bottom, cover board is that inside offers for muff joint 222 through-holes passed through；So that ratchet 210 is fixed in shell 230, and muff joint 222 can be exposed to connect fastening Part.

The operating of ratchet 210 needs the promotion by pawl 240, as shown in Fig. 2, pawl 240 is mounted on inner hollow In handle 100, when the utility model does not stress, 240 head of pawl of beveling passes through the logical of handle 100 and 230 junction of shell It is arranged in behind hole between the gear of ratchet 210, and smooth 240 tail portion of pawl passes through the bottom end phase of spring 250 and handle 100 Even.In the present embodiment, the bottom end of handle 100 is adjusting screw 260, can be by adjusting adjusting screw 260 to control spring 250 Elastic deformation degree to finely tune the stress and rotation of ratchet 210, obtain the usage mode of the most comfortable to adjust.

Specifically, in the present embodiment, also there is casing 300, handle 100 is set in casing 300 to protect handle 100 and prevent the loosening and loss of 200 components of disassembly and assembly structure.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but not deviate from the spirit of the utility model or surmount the range as defined in the claims.
