The axle that type pipe lower end periphery, right grip 22 are enclosed within driving gear shaft 17 is gone up and is constituted with driving gear shaft 17 and fixedlys connected secondaryly 23, and the axle head of driven gear shaft 21 is installed in to constitute in another stomidium of sleeve 12 and with sleeve 12 fixedlys connected secondary 24.The gear of the gear of driving gear shaft 17, planetary gear 18, planetary gear 19, planetary gear 20 and driven gear shaft 21 meshes successively.
＜embodiment two＞
The utility model is made up of spanner pawl 25, crank 26 and stud grip structure 27, and crank 26 is
The type pipe, left side grip 28 skies are enclosed within the upper end of crank 26, spanner pawl 25 through the lower end of the guide more than two groups 29 and crank 26 periphery constitute can be relative on, move down, can not be slidingly connected secondary 30 in relative rotation, stud grip structure 27 is made up of location structure 31 and clamping structure 32, location structure 31 is by chuck axis 33, chuck pin 34 and reseting elastic element 35 are formed, the axle head of chuck axis 33 freely is installed in 27 times stomidiums of crank, chuck pin 34 radially is installed on the chuck of chuck axis 33 and can moves relative to chuck on the axis direction of vertical chuck axis 33, and an end that is installed in the interior reseting elastic element 35 of chuck axis 33 stage casing lateral grooves is connected with chuck pin 34; Clamping structure 32 is for being through the flexible axle 36 in crank 26 axially extending bores, fixedlys connected with left grip 28 in the upper end of flexible axle 36, fixedlys connected with the axle head of chuck axis 33 in the lower end of flexible axle 36.
When the main double-screw bolt top nut of use＜embodiment one＞dismounting, spur chuck axis 13 downwards, chuck axis 13 secondary 16 is moved relative to sleeve 12 outwardly through being slidingly connected, chuck pin 14 moves relative to the chuck of chuck axis 13 under the effect of reseting elastic element 15, in chuck pin 14 all enters the chuck of chuck axis 13, spanner pawl 1 is enclosed within the groove of the nut 38 on the main double-screw bolt 37, and the chuck-end of chuck axis 13 is inserted in the counterbore 39 of main double-screw bolt 37, with spanner to pressing down, chuck axis 13 secondary 16 is moved in sleeve 12 relative to sleeve 12 through being slidingly connected, compression reseting elastic element 15, chuck pin 14 is in the state that desire ejects the chuck of chuck axis 13 under the effect of reseting elastic element 15, make right grip 22 around crank 2 little rotations, and through driving gear shaft 17, planetary gear 18,19,20, driven gear shaft 21, auxiliary connection 24, sleeve 12 and auxiliary connection 16 make the little thereupon rotation of chuck axis 13, aim at the pin-and-hole 40 of main double-screw bolt 37 until chuck pin 14, chuck pin 14 ejects and springs into pin-and-hole 40 from the chuck of chuck axis 13, make chuck axis 13 and main double-screw bolt 37 left grip 7 and the right grip 22 held with a firm grip that fuse, rotate counterclockwise crank 2 and through the guide more than two groups 8, spanner pawl 1 drives nut 38 and rotates counterclockwise, spanner pawl 1 moves up through straight tube 5 peripheries of auxiliary connection 9 relative cranks 2 simultaneously, the right grip 22 owing to hold with a firm grip, make between fixedly connected with it driving gear shaft 17 and the crank 2 and relatively rotate, but there be not absolute the rotation, and through three planetary gears 18,19,20, driven gear shaft 21, auxiliary connection 24, sleeve 12, auxiliary connection 16, chuck axis 13 and chuck pin 14, make main double-screw bolt 37 transfixions, thereby finish the operation of dismounting nut 38.When main double-screw bolt top nut is installed, only be that clockwise direction rotates crank 2, other steps are identical.
When the main double-screw bolt top nut of use＜embodiment two＞dismounting, job step is same as described above, but the left grip 28 of need holding with a firm grip makes main double-screw bolt transfixion through flexible axle 36, chuck axis 33 and chuck pin 34, thereby finishes dress, tear the operation of main double-screw bolt top nut open.
