Wrench assembly 100 of the invention is described below according to Fig. 1-Fig. 3.
Wrench assembly 100 according to the present invention includes the first spanner 110, the second spanner 120, the first locking member 130, second
Locking member 140 and third locking member 150, wherein one end of the first spanner 110 is adapted to fit on nut, the second spanner 120
One end is adapted to fit on bolt, and the first locking is just rotatably arranged in the other end and the second spanner 120 of the first spanner 110
The other end on, the second locking member 140 be rotatably arranged in the first spanner 110 the other end and the second spanner 120 it is another
On end, one end of third locking member 150 is removably arranged on the first locking member 130, third locking member 150 and the second locking
Part 140 is threadedly engaged to drive the first spanner 110 or the second spanner when rotating third locking member 150 or the second locking member 140
120 rotations.
As shown in Fig. 2, the one end fits of the second spanner 120 are in bolt when the one end fits of the first spanner 110 are on nut
It when upper, had a certain degree between the first spanner 110 and the second spanner 120, so that the other end of the first spanner 110 is pulled with second
There is biggish distance between the other end of hand 120, the first locking member 130 is fixed on the other end of the first spanner 110, the
Two locking members 140 are fixed on the other end of the second spanner 120, are connected by third locking member 150 and the first locking member 130
It connects, the other end of the other end and the second spanner 120 that can make the first spanner 110 connects, third locking member 150 and second
Locking member 140 by being threadedly engaged, rotation third locking member 150 make between third locking member 150 and the second locking member 140 away from
From shortening, it is possible thereby to shorten 110 other end of the first spanner at a distance from 120 other end of the second spanner, so that first pulls
Nut on one end of hand 110 relatively rotates with the bolt on one end of the second spanner 120.
Wrench assembly 100 according to the present invention has that the wide relevance grade of use scope is high, by by third locking member 150 and the
Two locking members 140 are threadedly engaged, and rotate third locking member 150 or/and the 4th locking member 140, so that the first spanner 110 or the
The rotation of two spanners 120 is greatly decreased disassembly or installs operating force required when nut.
As shown in figure 3, multiple latches 131 spaced apart are provided on the first locking member 130, the one of third locking member 150
The gasket 151 cooperated with latch 131 is provided on end, one end of the first locking member 130 setting latch 131 can be structured as two
Latch fixed pedestal, multiple latches 131 are arranged on two latch fixed pedestals, and are corresponding, third locking member 150
Upper set gasket 151 is disc, can be stuck on a pair of of latch 131, latch 131 have it is multipair, to be suitable for difference
Distance, the power passed over from gasket 151 can pass to the first locking member 130 by latch 131.
By setting latch 131 and gasket 151, effectively increase by 100 scope of application of wrench assembly, for different distance
Spanner can be cooperated by gasket 151 and slide calliper rule to solve, and using by the way of the cooperation of side, cooperation is simple square
Just.
One end of third locking member 150 is additionally provided with the mobile retention bead 152 of limitation gasket 151, and retention bead 152 can
To be fixed with bolts in one end of third locking member 150, gasket 151 is set in the end of third locking member 150, third
The end of locking member 150 could be formed with cylinder boss, limits to a direction of gasket 151, is arranged on cylinder boss
There is screw thread, retention bead 152 can be threadedly engaged by screw thread and cylinder boss, and gasket 151 is thus fixed on third locking
It on part 150, move gasket 151 can not, the transmission force that gasket 151 can be made stable.
Be provided on third locking member 150 with the second locking member 140 cooperation external screw thread, third locking member 150 it is another
