Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that the spanner of chuck is not installed.
The specific embodiment
A kind of spanner as shown in Figure 1, 2, comprises handle and the chuck 10 with bayonet socket 11 that is connected to handle front end, and bayonet socket 11, for blocking part to be demolished, is then pulled handle part to be demolished is unscrewed and pulled down.Handle of the present invention comprises support 30 and fixed handle 20, and support 30 and fixed handle 20 are lath-shaped and both plate faces are parallel to each other, and fixed handle 20 is hinged by the first jointed shaft with support 30, and the axle core of the first jointed shaft is perpendicular to the plate face of handle; Described chuck 10 is hinged on the front end of support 30, the plate face of chuck 10 is parallel to the plate face of support 30, the second jointed shaft 12 that so corresponding realization is hinged between the two is also perpendicular to the plate face of support 30, bayonet socket 11 is suspended at the outside of support 30 front ends, avoids support 30 to disturb bayonet socket 11 to block part to be demolished.Obviously, because chuck 10 is positioned at support 30 front ends, the hinge point of fixed handle 20 and support 30 is compared with the more close support of chuck 10 30 rear ends so.The present invention arranges torque-transmitting mechanisms between chuck 10 and the front end of fixed handle 20.That is to say when fixed handle 20 rotates around the first jointed shaft, effect chuck 10 by torque-transmitting mechanisms also can rotate around the second jointed shaft 12, bayonet socket on it 11 is inevitable so also can rotate, and bayonet socket 11 can change with the angle of the length direction of handle, main namely support 30 and fixed handle 20.
Namely such spanner can be adjusted the angle between chuck 10 and bayonet socket 11 and decreased food direction arbitrarily angledly, then bayonet socket 11 just can be clamped part to be demolished at any angle, then hold with a firm grip and pull fixed handle 20 and support 30, can unscrew part to be demolished, repeatedly repeating aforesaid operations can disassemble part to be demolished.This has just been avoided spanner cannot be clamped to parts or be clamped to parts but handle has been conflicted the situation that other parts can not be pulled because of the narrow space of use location.Such spanner can use at narrow space, and dismounting Isolating Switch etc. is positioned at parts narrow space, that common wrench cannot be dismantled.
As for described torque-transmitting mechanisms, can there is various ways, for example, around the first jointed shaft setting and affixed belt pulley or the gear of fixed handle, namely belt pulley or gear can synchronously rotate around the first jointed shaft with fixed handle, then chuck 10 is fixed on corresponding belt pulley or gear, this belt pulley or gear and support 30 front ends are hinged by the second jointed shaft 12, then with belt or chain, by laying respectively at the first jointed shaft, are connected with belt pulley or the gear at the second jointed shaft 12 places.Then operator pull fixed handle 20 be capable of regulating bayonet socket 11 towards, hold with a firm grip fixed handle 20 and support 30, synchronously pull both and can unscrew part to be demolished.Belt pulley and Gear Processing are easy to use, and the structure of spanner is also comparatively simple like this.Or fixed handle 20 is affixed with two worm gears respectively with chuck 10, two worm gears and fixed handle 20 and chuck 10 can be respectively rotate around jointed shaft separately, then between two worm gears, worm screw is set, when fixed handle 20 is when the first jointed shaft rotates, chuck 10 also can rotate, this also played adjust bayonet socket 11 towards effect.In such structure, the rotational angle of chuck 10 can accurately be controlled.Even, torque-transmitting mechanisms is the cylinder of a small size, the intake and exhaust valve of fixed handle operation cylinder, and the piston rod of cylinder is hinged on the end of chuck 10, so also can make chuck 10 around the second jointed shaft 12 rotations.Such structure is rapid operation also, especially dismantles size larger, particularly applicable while connecting closely parts.
In above-mentioned several structure, the length of torque-transmitting mechanisms preferably can also suitably change, namely can be by the long enough of belt or chain or the length of worm screw or cylinder or piston rod and the setting of the length of support 30 according to the difference of use occasion, just can only pull fixed handle 20 just by the very large angle of part to be demolished rotation, part to be demolished is unloaded, and only along with the rotation of its chuck 10, there is the less movement along support 30 length directions in spanner itself; Because be positioned at the spanner front portion of narrow space, the rotation around part to be demolished can not occur, this also can be called is that zero degree is pulled spanner and just can be dismantled parts.Such technical scheme just than only adjust bayonet socket 11 towards more optimizing, spanner uses more convenient.
The preferred torque-transmitting mechanisms of the present invention is that the front end at fixed handle 20 arranges sector 21, between chuck 10 and support 30, pinion 70 is set, chuck 10 can be to be " recessed " font, its rear portion the smooth of the edge transition, the plate face of chuck 10 reclines mutually with the card of pinion 70, the rear end of chuck 10 is fixed on the second jointed shaft 12, the middle part of chuck 10 is fixed in installation shaft 13, installation shaft 13 is affixed with the card of pinion 70, namely pinion 70 fixes as one with chuck 10 and can rotate around the second jointed shaft 12, the axle core of the second jointed shaft 12 is perpendicular to the plate face of support 30, the plate face of pinion 70 and fixed handle 20 front portions abuts on the upper face of support 30, pinion 70 forms gear drive with sector 21 and coordinates, its gearratio is less than 1.Fixed handle 20 long enoughs and pull laborsaving so on the one hand; Meanwhile, so need to rotate less angle because the gearratio that tooth coordinates is greater than 20 of 1 fixed handles, chuck 10 and bayonet socket 11 just can rotate larger angle, pull so fixed handle 20 and not only can, for adjusting the angle of bayonet socket 11, be convenient to clamp part to be demolished; And can directly pull fixed handle 20 and realize the function of wide-angle ground rotary part, be low-angle pull fixed handle 20, support 30 and fixed handle 20 rear portions can be by the larger angles of parts rotation from smaller angle, thereby parts are pulled down, reduced repeatedly hold assembly and the number of times of pulling spanner.Such spanner can not only be dismantled easily parts and pull more laborsaving.
Be more preferably the controlling organization that the sector 21 make on fixed handle 20 and pinion 70 are separated is set.So just can first fixed handle 20 and pinion 70 be separated, then directly rotary chuck 10 arrives the angle identical with part to be demolished, after hold assembly, fixed handle 20 is contacted with pinion 70, then integral body is pulled fixed handle 20 and support 30 or is pulled separately fixed handle 20 and carry out field-strip again.In such structure, fixed handle 20 length can be as far as possible long, pulls laborsaving.Can also between pinion 70 and fixed handle 20, transition gear 60 be set, fixed handle 20 forms successively transmission with transition gear 60, pinion 70 and coordinates, now need to guarantee that fixed handle 20 and the rotating ratio of pinion 70 are less than 1, namely pinion 70 rotating speeds must be still faster than the rotating speed of fixed handle 20, when assurance fixed handle 20 rotates less angle, pinion 70 just can rotate larger angle, for example pinion 70 is identical with transition gear 60 specifications, fixed handle 20 is less than 1 with the gearratio of transition gear 60, is preferably in 1:3 left and right.This had namely both increased number of gears, and controlling organization is also set simultaneously, and such spanner uses most convenient, because only increased a gear, so fixed handle 20 still has enough length, uses still very laborsaving; When the angle of chuck 10 required adjustment is larger, because transition gear 60 intervals fixed handle 20 and pinion 70, so no matter the great angle of chuck 10 rotation all there will not be chuck 10 to block fixed handle 20 along the axial lifting of the first jointed shaft or the space of putting down, namely can sharp use to greatest extent the effect of controlling organization, the angle of chuck 10 and bayonet socket 11 can be adjusted arbitrarily angledly.The gearratio data that adopt are also most popular, when the gearratio of, fixed handle identical with transition gear 60 specifications at pinion 70 20 and transition gear 60 is 1:3, during dismounting Isolating Switch, 20 of fixed handles need to rotate 30 °, Isolating Switch will half-twist and is departed from from Isolating Switch assembly, namely the gearratio of gear has more conventional occasion choose reasonable, further facilitates the use of spanner.
As for controlling organization, the hinge hole that can be fixed handle 20 and the first jointed shaft is mounting hole, hole length direction is along the length direction of support 30, then flexible member is set between support 30 and fixed handle and makes mounting hole rear end on fixed handle 20, namely away from one end of chuck 10 and the axle body of the first jointed shaft, contact cooperation, operating personnel can post-tensioning fixed handle 20 be separated itself and pinion 70.Or along the sheathed Compress Spring 23 of the axle body on the first jointed shaft top, the lower end of Compress Spring 23 leans with the plate face of fixed handle 20, upper end is kept out and coordinated with the split washer 24 on the first jointed shaft termination, user as shown on lift handle 20 can it is separated with pinion 70.Like this simple in structure, rapid operation, does not increase the overall dimensions of spanner yet.Conventionally fixed handle 20 and the front portion of support 30 laminating of all try one's best, reduces the overall dimensions of spanner, easy to use, and the rear portion of fixed handle 20 and support 30 is from the position of formation convenient operation person gripping, spanner rear portion formation opening shape as shown in the figure.
The position-limit mechanism of the rotational angle of restriction fixed handle 20 can also be set between fixed handle 20 and support 30, position-limit mechanism comprises kidney-shaped spacing hole or the groove 22 on the front end-plate face that is positioned at fixed handle 20, and the axle core of kidney-shaped spacing hole or groove 22 is in take on the circular arc that the axle core of the first jointed shaft is the center of circle; On the plate face of described support 30, corresponding position arranges limit shaft 31, and limit shaft 31 stretches in spacing hole or groove 22; Or position-limit mechanism is arranged on the block at support 30 edges of fixed handle 20 front end both sides, and block and support 30 fix as one.While pulling spanner like this, fixed handle 20 rotates to that extreme position is just stopped by block and no longer continues rotation, namely can be naturally and support 30 Complete Synchronizations, now also just there is no need operating personnel and apply external force and made fixed handle 20 with support 30 synchronization actions, this has further played the effect of rapid operation.
