Abstract

The invention relates to a movable spanner, which comprises a handle, a driving head which is fixedly arranged at one end of the handle, a movable jaw of which one end is a tooth part glidingly arranged at one end in a limit slide way, a pivot jaw of which one end is a limit part, a worm rod element arranged in an accommodating cavity and a baffle element arranged in a control cavity. The movable spanner uses the pivot jaw which can be pivoted; and when the pivot jaw is supported against or released by the baffle element, a positioning or pivoting condition can be generated so as to ensure that the movable spanner quickly changes the opening width. Moreover, the movable spanner capable of quickly changing the opening width has the advantage of excellent operability so as to reduce operation time.

The specific embodiment

See also Fig. 1 to Fig. 6, be the selected embodiment of the present invention shown in the figure.

Present embodiment provides a kind of monkey wrench, and it includes a lever 1, a driving head 2, a movable jaw 3, a pivot jaw 4, a worm screw element 5, reaches a block element 6, wherein:

This lever 1 is to utilize aluminium to make, and lever 1 one ends have a guide groove 11.Again, this driving head 2, be fixedly arranged on this lever 1 and have guide groove 11 1 ends, this driving head 2 has a spacing slideway 21, a room 22, reaches a control room 23, this room 22 is communicated with this spacing slideway 21, and room 22 communicates with the external world along its thickness direction, and these room 22 two relative sides have a screw 221, an and through hole 222, and through hole 222 is communicated with these control rooms 2

3, and this control room 23 sidewall in opposite directions respectively has a control hole 231, and this driving head 2 has protruded out a stopper 24 in spacing slideway 21 1 ends two sides.

This movable jaw 3, one end are one first operate portions 31, and the other end is a tooth portion 32, and tooth portion 32 is slidedly arranged in this spacing slideway 21.Again, this pivot jaw 4, the one end is one second operate portions 41, the other end then is a limiting section 42, this second operate portions 41 is for the stopper 24 that abuts against in this driving head 2, have an articulated section 43 in these pivot jaw 4 adjacent central positions, and articulated section 43 is hubbed in the end of this spacing slideway 21 away from this movable jaw 3, and makes limiting section 42 be positioned at this control room 23.

This worm screw element 5, be located in this room 22, worm screw element 5 includes a locking part 51, a worm screw 52 in regular turn, reaches an elastic component 53, wherein, this locking part 51 can wear and protrudes out this worm screw 52 in the other end from these worm screw 52 1 ends, and the protruding end of locking part 51 passes this elastic component 53, and locking part 51 is locked in the screw 221 of this driving head 2, impels these elastic component 53 1 ends to pass the through hole 222 of this driving head 2 and abuts against limiting section 42 in this pivot jaw 4.

This block element 6, be to be located in this control room 23, this block element includes an abutment 61, middleware 62, one reposition element 63, an and button 64, wherein, this abutment 61 has a chute 611, and be to be provided with the chute 611 that cooperates this abutment in the middle of this button 64, and has a delthyrium 641, and in this chute 611 be inserted with one the pin 65, this pin 65 passes the delthyrium 641 of this button 64, and this button 64 is limited in this chute 611, and button 64 convexedly stretches in the control hole 231 in this control room 23, and, abutted against this middleware 62 in chute 611 openends of abutment 61, middleware 62 is held in addition to support and is established this reposition element 63, so that this reposition element 63 is installed with and abuts against in the guide groove 11 of this lever 1.

See also Fig. 3 and Fig. 4, via said structure as can be known, under the normality, when using monkey wrench, then can utilize the A/F of adjusting in advance, in order to the work of doing to revolve lock or unscrewing screw, at this moment, the abutment 61 of this block element 6 just abuts against limiting section 42 in this pivot jaw 4 because of aforementioned reposition element 63, and the elastic component 53 of this worm screw element 5 is resisted against the limiting section 42 of this pivot jaw 4, and make second operate portions 41 of pivot jaw 4 abut against stopper 24 in this driving head 2, and then feasible pivot jaw 4 located, for doing the work of revolving the lock, unscrewing screw.

Opposite, please consult Fig. 5 and Fig. 6 in addition, in the work, if need reorientate monkey wrench when being sheathed on the position of screw, then can be extremely approaching with the head width of screw confession turn when sheathed because of the opening of monkey wrench, and be difficult to carry out.At this moment, the user then can push the button 64 of this block element 6, and the delthyrium 641 in the button 64 is moved towards opposite side, impel the hypotenuse of this delthyrium 641 to abut against the pin 65 that is fixed in this abutment 61, and make abutment 61 integral body towards reposition element 63 1 side translations, to cause this abutment 61 to break away from limiting section 42 in this pivot jaw 4, simultaneously, then because the limiting section 42 of pivot jaw 4 is not subjected to the restriction of abutment 61, then can produce suitable pivoting angle, be beneficial to monkey wrench and reorientate on opening and the screw confession head of turn.

By a pivotable pivot jaw, during action that the pivot jaw can be abutted against by a block element or discharge, and the situation that produces the location or pivot, and make monkey wrench can change its A/F fast.

Moreover, can change the monkey wrench of A/F fast, have splendid operability, and reach the purpose that reduces the operating time.

Certainly, still there are many examples in the present invention, therebetween the only variation on the details.See also Fig. 7 to shown in Figure 12, it is the second embodiment of the present invention, wherein this block element 6A also is located in this control room 23, having a button 64A is located in the control hole 231 of this driving head 2 and control room 23 UNICOMs, difference is, this button 64A has several groove 641A that is absorbed in for the limiting section 42 of pivot jaw 4 one ends, be a plurality of stopper 642A between each groove 641A, and have two relative oblique concave surface 643A, and this driving head 2 is provided with a screw 222 with respect to this oblique concave surface 643A position, in screw 222, be provided with the oblique concave surface 643A that a pin 66 is resisted against this button 64A, this pin 66 is to replace through a compression spring 67, and this compression spring 67 is replaced by a screw 68 and is locked in screw 222 location of this driving head 2, for block should pivot jaw 4 limiting section 42 and locate this pivot jaw 4.

By above-mentioned structure as seen, when general use, limiting section 42 ends of this pivot jaw 4 are the stopper 642A that keep out in this button 64A, thus when being set in screw head can as rotation (as Fig. 8 and shown in Figure 10); And desire revolution after spanner goes to certain limit, can push this button 64A, limiting section 42 ends of pivot jaw 4 can be absorbed in the groove 641A of button 64A, so spanner is when revolution, this pivot jaw 4 can as Fig. 9 with shown in Figure 11 and with movable jaw 3 relative to outwards moving, and do not moving under the screw head that is rotated, can after revolution, rotate once more.
