Abstract
The utility model provides an instrument of variable -ratio connects pole, the instrument connects the pole to include first end and the second end, first end and end the second end are torsion output end and torsion input respectively, the instrument meets the middle variable transmission structure that is equipped with of pole, variable transmission structure's both ends respectively with the second end with an end connection, size and transmission that variable transmission structure is used for changing torsion input torsion are held for torsion output. The utility model discloses the torsion input needs only rotatory low -angle, the angle that is more than the input will be exported to the torsion output end, has improved operating efficiency, also can operate on the contrary, can make to connect the pole not only to play the connection effect, can also regard as the dual function of booster or accelerator, enlarges the application scenario that connects the pole, simultaneously, the utility model discloses the gear train makes the power transfer efficiency who connects the pole high, feels.
Description
Technical field
This utility model is related to Wrench field, more particularly, to a kind of tool extension rod of variable-ratio.
Background technology
Extension bar is widely used hardware ＆ tools, and conventional only serves interconnection function.
Content of the invention
Technical problem to be solved in the utility model is to provide a kind of tool extension rod of variable-ratio, for this reason, this practicality is new
Type provides technical scheme below：
A kind of tool extension rod of variable-ratio is it is characterised in that described tool extension rod includes first end and the second end, institute
Stating first end and end the second end is torsion outfan and torsion input respectively, is provided with speed change knot in the middle of described tool extension rod
Structure, the two ends of described speed changing structure are connected with described the second end and described first end respectively, and described speed changing structure is used for changing
Become torsion input to input the size of torsion and pass to torsion outfan.
On the basis of using technique scheme, this utility model also can be using technical scheme further below：
Described speed changing structure includes first gear and the second gear being coaxially disposed and linking together, and is arranged on
3rd gear of one end, it is arranged on the 4th gear of the second end, the dead in line of the 3rd gear and the 4th gear, described
Two gears are engaged with the 3rd gear, and described first gear is engaged with the 4th gear；
Described second gear and the 3rd gear formation gear train, described first gear and the 4th gear formation gear train, two
Group gear train is all train of reduction gears or speed increasing gear group.By adjusting gear, the ratio of input and output moment of torsion can be made different.
Described tool extension rod also includes the housing between lid, lower cover and upper lid and lower cover, and described housing is provided with boss, institute
State boss to be used for making the 3rd gear and the 4th gear keep gap, described upper lid, lower cover and housing positioning speed changing structure
Described first end can be the sleeve that can be adapted to square head.Described the second end can be pulling of energy conforming sleeves
Handss.
Described housing is provided with the hole being adapted with the second end, speed changing structure and first end each position junction.
Due to adopting the technical solution of the utility model, the beneficial effects of the utility model are：This utility model torsion is defeated
As long as entering one low-angle of end rotation, torsion outfan will export the angle much larger than input, improve operating efficiency, also may be used
Inverse operation, can make extension bar not only act as interconnection function moreover it is possible to dual-use function as booster or accelerator, expand extension bar
Application scenario, meanwhile, this utility model gear train makes the power transmission efficiency of extension bar high, good hand touch.

Specific embodiment
As illustrated, a kind of tool extension rod of variable-ratio, described tool extension rod includes first end 3 and the second end 5, institute
Stating first end and end the second end is torsion outfan or torsion input respectively, is provided with speed changing structure in the middle of described extension bar
4, the two ends of described speed changing structure 4 are coordinated with described the second end 3 and described first end 5 respectively, and described speed changing structure 4 is used for
Change first end 3 to input the size of torsion and pass to the second end 5.
Described speed changing structure 4 and described the second end 3 and the cooperation of described first end 5 groove.
Described speed changing structure 4 is the first gear 7 that is coaxially disposed and rotates simultaneously and second gear 8, and is arranged on the
3rd gear 9 of one end 5, the 4th gear 10 being arranged on the second end 3 engage, and described second gear 8 and the 3rd gear 9 are nibbled
Close, described first tooth 7 is taken turns and the 4th gear 10；Described second gear, the 3rd gear and described first gear formed gear train, the
Four gear engagements form gear train, and two groups of teeth wheel group is all train of reduction gears or speed increasing gear group.The different ratio of four gears,
May result in the ratio of input and output moment of torsion different.
Described first end 5 is the sleeve that can be adapted to square head.
Described the second end 3 be can conforming sleeves ratchet spanner.
Described tool extension rod also includes covering the housing 6 between 1, lower cover 2 and upper lid 1 and lower cover 2, described upper lid 1, lower cover
2 and housing 6 positioning speed changing structure.Described housing is provided with boss 12, and described boss 12 is used for making the 3rd gear and the 4th gear protect
Hold gap.Boss 12 can effectively prevent the friction of upper and lower two face of gears.Described housing 6 is provided with and the second end, speed change
The hole 11 that structure and first end each position junction are adapted.
