Adjustable the turn of the screw spanner described in the present embodiment, can be by the adjusting block 3 of installation different number, to target
Nut is slightly accommodated, and is further fixed again by mobile movable block to target nut later, the stability of aid can be improved, into
And improve the stability that operation was tightened to target nut or unscrewed to spanner.
Embodiment 2
Adjustable the turn of the screw spanner described in the present embodiment is substantially the same manner as Example 1, the difference is that:
As shown in figure 3, the hand-held part 102 is a cylindrical body 1021, it is equipped with the second threaded hole 1022 in cylindrical body 1021,
Second threaded hole 1022 is connected to the first threaded hole 1023 on regular hexagon sleeve 101；Moving portion 201 is screw rod；Moving portion
201 sequentially pass through the second threaded hole 1022 and the first threaded hole 1023, are equipped with telescopic head close to 101 one end of regular hexagon sleeve
202；Moving portion 201 is installed on the inner surface of 1024 bottom of pedestal far from 202 one end end of telescopic head；In 1024 side wall of pedestal
Surface is threadedly coupled the outer surface of cylindrical body 1021, and pedestal 1024 can be moved synchronously with moving portion 201.
1024 side wall inner surfaces of pedestal are equipped with internal screw thread from its top to bottom, 1021 outer surface of cylindrical body from bottom extremely
Its position connecting with regular hexagon sleeve 101 is equipped with external screw thread；Internal screw thread and externally threaded maximum length of fit, which are greater than, moves
The difference of dynamic 201 length of portion and 1021 length of cylindrical body；External screw thread is synchronous screw thread with the screw thread in moving portion 201.
In use, operation is substantially same as Example 1, only because pedestal 1024 can be moved synchronously with moving portion 201, institute
It rotating base 1024 can be passed through, and then realizes that moving portion 201 is mobile to 101 side of regular hexagon sleeve, and then drives flexible
First 202 is mobile, target nut is fixed by flexible face 203, then nut is tightened or unscrewed in rotating hand portion 102.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
