The specific embodiment

Aforementioned and other technology contents, characteristics and effect about the utility model, below cooperate in the explanation of a plurality of preferred embodiments with reference to the accompanying drawings, can clearly present, the spanner that the utlity model has quick change formula joint will be elaborated below by most preferred embodiment and accompanying drawing:

Referring to Fig. 2, shown in Figure 3, the spanner that the utlity model has quick change formula joint consists predominantly of a wrench body 20 and a connector unit 30 in first preferred embodiment, then, and after again the shape of above-mentioned member and combination situations being specified in.

Wrench body 20 has a socket part 21 and by socket part 21 outward extending shank parts 22, this socket part 21 is concaved with a sleeve joint hole 211 in the end centre, be positioned at sleeve joint hole 211 outer side edges centre and have a chamfered section 212, in the present embodiment, this sleeve joint hole 211 is to be cubic rectangular opening, certainly the dealer also can make this sleeve joint hole 211 other non-circular void shapes, the outer peripheral face of this socket part 21 is provided with a depressed part 213, this depressed part 213 slightly is half-circle-arc shape, with socket part 21 outer surfaces is to do at a predetermined angle to tilt to be recessed into, can can pinch easily into for human finger, the middle place that is positioned at depressed part 213 more offers the locating hole 214 that always passes to sleeve joint hole 211 thoroughly, this shank part 22 is extended with predetermined length, just is available for users to hand and grips.

Referring to Fig. 4, shown in Figure 5, connector unit 30 has one and is the driving head 31 of being scheduled to profile, one by the extended bolt jointing part 32 in driving head 31 rear ends, and one bullet be located at the clamping piece 33 at bolt jointing part 32 outer peripheral face places, in the present embodiment, this driving head 31 offers a plum blossom hole 311 at the place, centre, the applicable bolt element that comes the polygonal head shapes of switching, this bolt jointing part 32 is rectangular post shapes, just can be inserted in the sleeve joint hole 211 of wrench body 20, the place is concaved with a post hole 321 that can supply clamping piece 33 to be inserted in the middle of its periphery, this clamping piece 33 includes a clip head 331 and a spring 332, these clip head 331 peripheries have a flange 3311, bolt jointing part 32 is behind the 321 outboard peripheries rivetings of post hole, the meat that extrudes is thick just can be formed spacing to clip head 331 flanges 3311, this spring 332 is nested with can be done buttedly in post hole 321 to clip head 331 lower ends, makes clip head 331 have towards the strength of lateral direction springing.

More than for the utlity model has the spanner structure of quick change formula joint and the general introduction of shape, then, again the effect statement that combination kenel of the present utility model and expection can be reached as after.

Referring to shown in Figure 6, when the user will assemble wrench body 20 and connector unit 30, as long as allowing connector unit 30 bolt jointing parts 32 aim at wrench body 20 sleeve joint holes 211 just directly is inserted in and can finishes, the clamping piece 33 of connector unit 30 is when beginning to enter sleeve joint hole 211, can successfully compress to pass through sleeve joint hole 211 along chamfered section 212, when clamping piece 33 just moves to locating hole 214 positions, clip head 331 be subjected to spring 332 upspring to, can protrude out and snap in the locating hole 214, so connector unit 30 just can combine with wrench body 20 apace and fix.

Referring to shown in Figure 7, when the user wants to change the connector unit of different types, the connector unit 30 that needs will be fixed on the wrench body 20 is removed, the user is as long as push downwards this clip head 331 with finger, clip head 331 just can move down and take off with locating hole 214 and pull, this moment, the user outwards extracted with another hand grip connector unit 30 again, and this connector unit 30 just can be separated with wrench body 20 easily, as shown in Figure 5.

Referring to shown in Figure 8, the utility model is in second preferred embodiment, wrench body 20 can be assembled another connector unit 40, another connector unit 40 has a driving head 41, a bolt jointing part 42 and a clamping piece 43 equally, different with a last embodiment is, this driving head 41 is drive post 411 that middle installing one has the ratchet one-way function, and this drive post 411 is the suitable sleeve (figure does not show) of socket again, so as to adapting to the demand of various different operatings.

Referring to shown in Figure 9, the utility model is in the 3rd preferred embodiment, wrench body 20 can be assembled another connector unit 50, another connector unit 50 has a driving head 51, a bolt jointing part 52 and a clamping piece 53 equally, different with a last embodiment is, this driving head 51 has an opening 511 in the outside, can be fit to be used for the bolt element of switching four angle heads or turret head.

In sum, the spanner that the utlity model has quick change formula joint is that the use problem at general spanner 10 makes improvement, technological means of the present utility model mainly is to utilize wrench body 20 that sleeve joint hole 211 is set to be inserted in fast for connector unit 30 bolt jointing parts 32, connector unit 30 relends by clamping piece 33 bullets and pulls in wrench body 20 locating holes 214, can allow connector unit 30 fix apace with wrench body 20 combines, so the utility model allows the user can indiscriminately ad. as one wishes change the connector unit 30 of different types, 40,50, so as to being applicable to the switching different types, the bolt of size, quite convenient in the use, and each connector unit 30 of the utility model, 40,50 all can dismantle or install on wrench body 20 apace, more can effectively promote operating efficiency.
