Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of improvement ratchet wrench is provided, and its transmission is simple, and spanner handle can be assisted reinforcing, and expansion link can bend, and transmission direction can be any direction, and is applied widely.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of universal box socket set, comprise driving end, the spanner seat that branch sleeve is arranged in the described driving end, driving end is connected and fixed seat, it is characterized in that: connect the pinion that the first end of spanner is provided with the side's of having tooth at described holder, the gear wheel engagement of 2 side's of having teeth on described pinion and the described spanner seat, described pinion gear face when meshing with described gear wheel is orthogonal, the interior circle of described gear wheel has ratchet and conversion gear engagement, one positive and negative knob is positioned at the spanner seat, porose top cap and the top cap spring of holding on the described positive and negative knob, described top crown is lived the bottom of conversion gear, the other end of described holder is by an end of the first connector loose joint connecting rod, and a loop bar is actively set on the connecting rod, and can be by the other end of the second connector loose joint connecting rod.
For optimizing technique scheme, the measure that the utility model is taked also comprises:
On described holder, be with boosting-rod.
Described conversion gear has 4, the every pair of conversion gear respectively with the ratchet engagement of a gear wheel.
There are spring and steel ball in the two ends of described connecting rod, and described steel ball is embedded in the groove of connector.
Spring and steel ball are arranged on the described connector, and described steel ball can be embedded in the groove of described loop bar.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, designed novel square gear right angle transmission, simple in structure, the parts manufacturing process is simple, reliable transmission, not only can lean on the rotating band wrench seat of loop bar self to rotate and work, can also pass to radially moment of torsion of driving end by radially pulling of loop bar;
2, connecting rod can be bent into various ways, makes that transmission direction can be an any direction, suits to work under multiple station;
3, boosting-rod can be pulled out and is enclosed within on the collapsible expansion link, the arm of force when having prolonged work.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
With reference to accompanying drawing, the utility model comprises driving end 7, the spanner seat 11 that branch sleeve is arranged in the described driving end 7, driving end 7 is connected and fixed seat 10, connect the pinion 9 that driving end 7 one ends are provided with the side's of having tooth 21 at described holder 10, gear wheel 3 engagements of 2 side's of having teeth 5 on described pinion 9 and the described spanner seat 11, pinion 9 gear face with gear wheel 3 engagements the time is orthogonal.The interior circle of described gear wheel 3 has ratchet 8 and conversion gear 6 engagements, and conversion gear 6 has 4, the every pair of conversion gear 6 respectively with ratchet 8 engagements of a gear wheel 3.One positive and negative knob 4 is positioned at spanner seat 11, and porose top cap 2 and the top cap spring 1 of holding on the described positive and negative knob 4, top cap 2 and top cap spring 1 have 2 covers, whenever are with the bottom that 1 top cap spring 1 and 2,4 top caps 2 of 2 top caps withstand 4 conversion gears 6 respectively.Turn positive and negative knob 1, make conversion gear 6 rotate an angle by top cap 2.At this moment, conversion gear 6 plays the single direction ratchet effect, and gear wheel 3 can only be made folk prescription to rotation under the effect of interior round ratchet 8.Turn positive and negative knob 1 to other direction, gear wheel 3 can only be made the folk prescription of other direction to rotation under the effect of interior round ratchet 8.The other end of described holder 10 is by an end of first connector, 14 loose joint connecting rods 15, and a loop bar 13 is actively set on the connecting rod 15, and can be by the other end of second connector, 16 loose joint connecting rods 15.There are spring 20 and steel ball 18 in the two ends of connecting rod 15, and described steel ball 18 is embedded in the groove 23 of connector, plays the role of positioning.Spring 19 and steel ball 17 are arranged on the described connector, and described steel ball 17 can be embedded in the groove 22 of described loop bar 13, plays fixation when loop bar 13 draws in.On holder 10, also be with boosting-rod 12.
