And positioning；Described torque conducting subassembly（3）It is assemblied in fixed board component（2）On, it is described for the torque transmission of torque spanner
Torque conducting subassembly（3）Pre-screwing nut is clamped, after tentatively finding installation site accurately, is placed on relevant position.
Preferably, pass through the adjustment axis（2-4）, adjustment fixing plate（2-1）Height.
Preferably, pass through alignment pin（2-5）, make fixed plate（2-1）Realize in positioning disk（1-1）On positioning, and then
Guide the installation site of pre-screwing nut.
Preferably, pass through knurled nut（3-9）, make torque conducting subassembly（3）It is fixed on fixed plate（2-1）On, by solid
Fixed board（2-1）On locating slot torque conducting subassembly is determined（3）Position, while also determine the installation position of pre-screwing nut
Put.
Preferably, pass through drive shaft（3-8）, the transmission of torque spanner torque is realized, gradually reduces fixed plate（2-1）'s
Highly, so as to realizing the function of screw nut pre-screwing.The utility model device passes through positioning disk component（1）, fixed board component
（2）, torque conducting subassembly（3）, screw nut pre-screwing work is smoothly quickly completed, reduces labor strength, saves labor
Dynamic cost, improves efficiency of assembling.
