21, hole well 3, bolt 4 to be torn open, handle jacket 5, handle 51, lock-screw 6, nut 7 to be torn open waits disassembling 8, body 9.
Specific implementation mode
In Fig. 1, a kind of hole well spanner, interior bar 1 is rotatably socketed in outer loop bar 2, the end in 2 one end of outer loop bar
Equipped with wrench socket 21, the same end of interior bar 1 is equipped with attaching nut 12 or screw rod；
The locking device for locking the rotation of interior bar 1 is equipped between outer loop bar 2 and interior bar 1.Thus structure, dress of the invention
Set, can individually lock bolt 4 to be torn open either nut 7 to be torn open convenient for nut 7 be torn open or nut be torn open 7 and waiting tearing open
Bolt 4 takes out together, and operating personnel need to only operate in the well head part of ground hole well 3, significantly reduce labor intensity.
In preferred scheme such as Fig. 3, described 21 one end of wrench socket is equipped with the torque for delivering torque to nut
Transfer part, the other end are fixedly connected with outer loop bar 2.
In preferred scheme such as Fig. 3, described 21 one end of wrench socket is equipped with the torque for delivering torque to nut
Transfer part, the other end are connect with outer loop bar 2 by ratchet mechanism, and ratchet mechanism is being not shown in figure.Thus structure, by reciprocal
Pulling can be dismantled, convenient for improving removal efficiency.
In preferred scheme, the torque transfer part is the sleeve that interior hexagonal or inner wall are equipped with serration.
In preferred scheme such as Fig. 1,3, handle jacket 5, taper knob are equipped in the one end of outer loop bar 2 far from wrench socket 21
Cylinder 5 is equipped with handle 51.
In preferred scheme such as Fig. 1,3, the locking device is at least one locking being threadedly coupled with handle jacket 5
Screw 6, the outer wall vertical of the axis and interior bar 1 of lock-screw 6.
In preferred scheme such as Fig. 1,2, torque portion 11 is equipped in the one end of interior bar 1 far from attaching nut 12.
In preferred scheme, the torque portion 11 is outer polygon end head, inner polygon sleeve or radial through-hole.
In preferred scheme such as Fig. 3,4, interior bar 1 is rotatably socketed in housing by the first axle sleeve 13 and the second axle sleeve 14
In bar 2.The first axle sleeve 13 and the second axle sleeve 14 in this example reduce the axle sleeve of frictional force using polytetrafluoro etc..
In the position close to 2 top of outer loop bar, 1 outer wall of interior bar is equipped with scale 15；Judge that the precession of interior bar 1 is deep by scale
Degree, or judge the height that outer loop bar 2 is unscrewed, it avoids being detached from nut 7 to be torn open in the bottom of hole well 3 bolt 4 to be torn open.
The spring 17 for buffering is additionally provided between interior bar 1 and outer loop bar 2.Preferably, in interior bar 1 close to the position at top
Position limiting pile 16 has been installed, spring 17 is equipped between position limiting pile 16 and the top end surface of outer loop bar 2.Spring in interior example is upon compression
The weight of interior bar 1 can be partly born, and there is sufficiently long compression travel.Thus structure avoids the collision between component from making
Part deformation, such as prevent the end collision of attaching nut 12 and bolt 4 to be torn open and cause deformed threads.
By taking optimal embodiment as an example, in Fig. 1, in use, when only needing to take out when tearing nut 7 open, 1 end of interior bar is set
Screw rod is set, this example middle screw rod is tightened and locked with attaching nut 12.After interior bar 1 and outer loop bar 2 are socketed, it is put into hole well 3
Interior, the wrench socket 21 of outer loop bar 2 is socketed with nut 7 to be torn open, the handle 51 of rotational handle sleeve 5, and nut 7 to be torn open is made to unclamp,
It is rotated further handle 51, until nut 7 to be torn open, which is detached from, waits disassembling 8, rotates interior bar 1, makes the screw rod of 1 end of interior bar and nut to be torn open
7 are threadedly coupled, and lift interior bar 1 and outer loop bar 2, i.e., dismantle nut 7.When needing to take out wait tearing bolt 4 and when tearing nut 7 open open,
Attaching nut 12 is only arranged in 1 end of interior bar, after interior bar 1 and outer loop bar 2 are socketed, is put into hole well 3, the spanner of outer loop bar 2
Sleeve 21 is socketed with nut 7 to be torn open, unscrews nut 7 to be torn open, stop operating outer loop bar 2, rotates backward interior bar 1,1 end of interior bar
Attaching nut 12 is threadedly coupled with bolt 4 to be torn open, is rotated further outer loop bar 2, keeps attaching nut 12 locked with nut 7 to be torn open.It will
Lock-screw 6 is tightened, and interior bar 1 or outer loop bar 2 are rotated backward, and so that bolt 4 to be torn open is unscrewed, is lifted interior bar 1 and outer loop bar 2, i.e., will
Bolt 4 to be torn open and nut 7 to be torn open take out.In demolishing process, the depth for judging to be screwed by scale 15, raising is disassembled into
Power.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as the limitation for the present invention, this Shen
Please in embodiment and embodiment in feature in the absence of conflict, mutually can arbitrarily combine.The protection model of the present invention
