Description of drawings
Fig. 1 is a 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 that is connected the band bayonet socket 11 of handle front end, and bayonet socket 11 is used to block part to be demolished, pulls handle then part to be demolished is unscrewed and pulls 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 first jointed shaft with support 30, and the axle core of 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, second jointed shaft 12 that so corresponding realization is hinged between the two also is 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 of chuck 10 is positioned at support 30 front ends, the hinge point of fixed handle 20 and support 30 is than chuck 10 more close supports 30 rear ends so.The present invention is provided with torque-transmitting mechanisms between the front end of chuck 10 and fixed handle 20.That is to say when fixed handle 20 rotates around first jointed shaft, effect chuck 10 by torque-transmitting mechanisms also can rotate around second jointed shaft 12, bayonet socket on it 11 must also can rotate so, and bayonet socket 11 can change with the angle of the length direction of handle, main support 30 just and fixed handle 20.
Just such spanner can be adjusted the angle between chuck 10 and bayonet socket 11 and the decreased food direction arbitrarily angledly, bayonet socket 11 just can be clamped part to be demolished at any angle then, hold with a firm grip then 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 can't be clamped to parts or be clamped to parts but handle has been conflicted the situation that other parts can not be pulled with regard to having been avoided spanner because of the space of use location is narrow and small.Such spanner can use at narrow space, and dismounting Isolating Switch etc. is positioned at parts narrow space, that common wrench can't be dismantled.
As for described torque-transmitting mechanisms various ways can be arranged, for example around the first jointed shaft setting and affixed belt pulley or the gear of fixed handle, just belt pulley or gear can synchronously rotate around first jointed shaft with fixed handle, chuck 10 is fixed on corresponding belt pulley or the gear then, this belt pulley or gear and support 30 front ends are hinged by second jointed shaft 12, will lay respectively at the belt pulley at first jointed shaft and second jointed shaft, 12 places or gear with belt or chain then and be connected and get final product.Then the operator pull fixed handle 20 can adjust bayonet socket 11 towards, hold with a firm grip fixed handle 20 and support 30 are pulled both synchronously and can be unscrewed part to be demolished.Belt pulley and Gear Processing are easy to use, and the structure of spanner is also comparatively simple like this.Perhaps 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 separately jointed shaft, between two worm gears worm screw is set then, when fixed handle 20 when first jointed shaft rotates, chuck 10 also can rotate, this also played adjust bayonet socket 11 towards effect.The rotational angle of chuck 10 can accurately be controlled in such structure.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 12 rotations of second jointed shaft.Such structure is rapid operation also, and it is bigger especially to dismantle size, and is particularly suitable when connecting closely parts.
The length of torque-transmitting mechanisms preferably can also suitably change in above-mentioned several structure, the long enough that the length of the length of belt or chain or worm screw or cylinder or piston rod and support 30 can be provided with just according to the difference of use occasion, just can only pull fixed handle 20 just with the very big angle of part to be demolished rotation, part to be demolished is unloaded, and less moving along support 30 length directions only takes place in spanner itself along with the rotation of its chuck 10; Because be positioned at the spanner front portion of narrow space rotation around part to be demolished can not take place, 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 optimizing more, spanner uses more convenient.
The preferred torque-transmitting mechanisms of the present invention is that the front end at fixed handle 20 is provided with sector 21, between chuck 10 and support 30, pinion 70 is set, chuck 10 can be to be " recessed " font, its rear part edge smooth transition, the plate face of chuck 10 reclines mutually with the card of pinion 70, the rear end of chuck 10 is fixed on second jointed shaft 12, the middle part of chuck 10 is fixed on the installation shaft 13, installation shaft 13 is affixed with the card of pinion 70, just pinion 70 fixes as one with chuck 10 and can rotate around second jointed shaft 12, the axle core of 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 constitutes gear drive with sector 21 and cooperates, and its gearratio is less than 1.Fixed handle 20 long enoughs and pull laborsaving so on the one hand; Simultaneously, so because the gearratio that tooth cooperates needs to rotate less angle greater than 20 of 1 fixed handles, chuck 10 and bayonet socket 11 just can rotate bigger angle, pull the angle that fixed handle 20 not only can be used to adjust bayonet socket 11 so, are convenient to the clamping part to be demolished; And can directly pull fixed handle 20 and the function of realization wide-angle ground rotary part, be low-angle pull fixed handle 20, support 30 can be with the bigger angle of parts rotation from smaller angle with fixed handle 20 rear portions, thereby parts are pulled down, reduced repeatedly hold assembly and the number of times of pulling spanner.Such spanner can not only be dismantled parts easily and pull more laborsaving.
Be more preferably the controlling organization that the sector 21 make on the fixed handle 20 and pinion 70 are separated is set.So just can earlier fixed handle 20 and pinion 70 be separated, directly rotary chuck 10 arrives the angle of coincideing with part to be demolished then, fixed handle 20 is contacted with pinion 70 behind the hold assembly, integral body is pulled fixed handle 20 and support 30 or is pulled fixed handle 20 separately and carry out field-strip then again.Fixed handle 20 length can be long as far as possible in such structure, pulls laborsaving.Can also between pinion 70 and fixed handle 20, transition gear 60 be set, fixed handle 20 constitutes transmission successively with transition gear 60, pinion 70 and cooperates, need to guarantee that the rotating ratio of fixed handle 20 and pinion 70 is less than 1 this moment, just pinion 70 rotating speeds must be still faster than the rotating speed of fixed handle 20, pinion 70 just can rotate bigger angle when assurance fixed handle 20 rotated less angle, for example pinion 70 is identical with transition gear 60 specifications, the gearratio of fixed handle 20 and transition gear 60 is preferably in about 1:3 less than 1.This had just both increased number of gears, and controlling organization also is 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 big, because transition gear 60 at interval fixed handle 20 and pinion 70, no matter do not block fixed handle 20 along the axial lifting of first jointed shaft or the space of putting down so chuck 10 can not appear in the great angle of chuck 10 rotations, just can sharp use the effect of controlling organization to greatest extent, the angle of chuck 10 and bayonet socket 11 can be adjusted arbitrarily angledly.The gearratio data that adopted also are to use the most widely, when the gearratio of, fixed handle identical with transition gear 60 specifications at pinion 70 20 and transition gear 60 is 1:3,20 of fixed handles need to rotate 30 ° during the dismounting Isolating Switch, Isolating Switch will half-twist and is broken away from from the Isolating Switch assembly, just the gearratio of gear has more occasion choose reasonable commonly used, further facilitates the use of spanner.
As for controlling organization, the hinge hole that then can be the fixed handle 20 and first jointed shaft is a mounting hole, the hole length direction is along the length direction of support 30, be provided with between support 30 and fixed handle then that flexible member makes mounting hole rear end on the fixed handle 20, just the end away from chuck 10 contacts cooperation with the axle body of first jointed shaft, operating personnel can post-tensioning fixed handle 20 be separated itself and pinion 70.Perhaps along the sheathed compression spring 23 of the axle body on the first jointed shaft top, the lower end of compression spring 23 leans with the plate face of fixed handle 20, the upper end keeps out with the split washer 24 on the first jointed shaft termination and cooperate, the user as shown on lift handle 20 and it can be separated with pinion 70.Like this simple in structure, rapid operation does not increase the overall dimensions of spanner yet.Usually fixed handle 20 and the front portion of support 30 applyings of all try one's best reduces the overall dimensions of spanner, and be easy to use, and the position of operator's gripping, spanner rear portion formation opening shape as shown in the figure are convenient to from formation in the rear portion of fixed handle 20 and support 30.
The position-limit mechanism of the rotational angle of restriction fixed handle 20 can also be set between fixed handle 20 and the support 30, position-limit mechanism comprises waist shape spacing hole or the groove 22 on the front end-plate face that is positioned at fixed handle 20, and the axle core that the axle core of waist shape spacing hole or groove 21 is in first jointed shaft is on the circular arc in the center of circle; The corresponding position is provided with limit shaft 31 on the plate face of described support 30, and limit shaft 31 stretches in spacing hole or the groove 21; Perhaps 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.Fixed handle 20 rotates to that extreme position is just stopped by block and no longer continues rotation when pulling spanner like this, just can be synchronous fully with support 30 naturally, also just there is no need operating personnel this moment and apply external force and made fixed handle 20 with support 30 synchronization actions, this has further played the effect of rapid operation.
