The hole wall of the thick section of described stepped hole is provided with inner groove corresponding with the position of outer groove, in outer groove and inner groove Equipped with multiple balls, between the cell wall of described ball and outer groove, it is provided with described setting gap.
Described setting gap is at least a times of the pitch of described screw thread.
This utility model is only by limited portions such as connecting seat, Step Shaft, actuating sleeve, handle, drive shaft, driving and driven bevel gears Part is constituted, so that this utility model has the advantages that structure is simple, low manufacture cost, it is using can the completing of convenient power-saving The fastening of flare nut, is greatly improved working performance.
Brief description
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the sectional view of the line A-A along along Fig. 1;
Fig. 4 is the structural representation of this utility model use state.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, flare nut drives spanner to include connecting seat 1 and Step Shaft 2, is provided with axle in connecting seat 1 To through hole, the thin segment of Step Shaft 2 is rotatably connected in the endoporus of connecting seat 1.It is provided with its axial step of insertion in Step Shaft 2 Hole 3, the thin segment of stepped hole 3 is corresponding to the thin segment position of Step Shaft 2, the position of thick section of stepped hole 3 and the thick section of Step Shaft 2 Position is corresponding.Stepped hole 3 thin segment inwall is provided with screw thread 4, is provided with actuating sleeve 5, sets and pass through in actuating sleeve 5 in the thick section of stepped hole 3 Lead to its axial taper hole 6, the outer peripheral face of actuating sleeve 5 is provided with outer groove 7, the hole wall of the thick section of described stepped hole 3 is provided with outward The corresponding inner groove in position 14 of annular groove 7.It is connected with the hole wall of the thick section of stepped hole 3 and cross inner groove 14 and stretch in outer groove 7 Driving post 8, drive post 8 can slide outer groove 7 in, be provided with outer groove 7 can stop drive post 8 slip projection 9, driving Post 8 can be arranged on and point be listed in two of projection 9 both sides, drive and be provided with setting gap between post 8 and the cell wall of outer groove 7, this sets The size of fixed gap is at least a times of the pitch of described screw thread 4.Outer groove 7 and inner groove 14 are built with multiple balls 15, institute That states that ball 15 can make Step Shaft 2 and actuating sleeve 5 relatively rotates held stationary.Between the cell wall of described ball 15 and outer groove 7 It is provided with above-mentioned setting gap.It is connected with driven between connecting seat 1 and the thick section of Step Shaft 2 on the thin segment of Step Shaft 2 Bevel gear 10, connecting seat 1 is connected with handle 11, is rotatably connected to drive shaft 12 in handle 11, one end of drive shaft 12 equipped with The driving gear 13 being engaged with driven wheel of differential 10, the other end are provided with for the connecting portion 16 with the power connector of driving means.
Referring to Fig. 1 and Fig. 4, use process of the present utility model is further described.
First flare nut 17 is spun on bolt 18, then make bolt 18 cross actuating sleeve 5 taper hole 6 and make bolt 18 with Screw thread 4 on stepped hole 3 thin segment inwall is spirally connected, and starts the driving means with drive shaft 12 power connector(In figure is not shown)Order about Drive shaft 12 rotates, and then passes through driving gear 13 and driven wheel of differential 10 drives Step Shaft 2 to rotate, Step Shaft 2 is along bolt 18 Actuating sleeve 5 can be driven in the process of movement mobile and so that the wall of taper hole 6 is tightly pressed against on flare nut 17, Step Shaft 2 continues Continuous rotation, drives post 8 can push projection 9 and drives actuating sleeve 5 to rotate, actuating sleeve 5 can be with flare nut in the presence of frictional force 17 are rotated further, thus realizing the fastening of flare nut 17.
After the completion of fastening, reversely rotate Step Shaft 2, drive post 8 to leave projection 9, actuating sleeve 5 will not be ordered about and rotate, thus Also flare nut 17 will not be made to invert, due to driving between the cell wall of post 8 and outer groove 7 and between the cell wall of ball 15 and outer groove 7 It is equipped with gap, Step Shaft 2 can go up shifting one segment distance, relieve and actuating sleeve 5 is extruded, actuating sleeve 5 also relieves to cone simultaneously The extruding of nut 17, continues reverse step axle 2, and after projection 9 and another driving post 8 are with contacting, actuating sleeve 5 is also with Step Shaft 2 rotate backward and are gradually distance from flare nut 17, and continuing to rotate backward Step Shaft 2 can drive spanner from bolt 18 by flare nut Back off, the fastener cycle of frustum nut completes.
