Description
[technical field]
It a kind of pulls the utility model relates to hand-operated tools field more particularly to suitable for the omnipotent of field engineer operation
Hand.
[background technique]
Spanner is a kind of hand tools that bolt, screw, nut or other threaded fasteners are twisted using lever principle, is pulled
Hand, which is usually formed in the one or both ends of shank, can twist the opening or sets of holes of bolt or nut in shank application external force, use
When threadingly direction of rotation shank apply external force, bolt or nut can be twisted.Current spanner is largely special spanner,
It is all limited by size and shape, the fastener of especially present import equipment mostly uses size manufacture made in Great Britain or made in U.S.A, does not have
Method is gone to tighten or be loosened with existing spanner, to complete the tool that task often requires to use a variety of different systems, and
It, even more can not the spanner of all type and size all bands is complete in field work.
The utility model is exactly researched and proposed in view of the deficiency of the prior art.
[utility model content]
The technical problems to be solved in the utility model is, the deficiencies in the prior art and a kind of portable, Simple assembled is provided
Monkey wrench, do not limited by nut specification or shape, have it is applied widely, it is at low cost, it is easy to operate the features such as.
In order to solve the above technical problems, the utility model uses following technical scheme: a kind of monkey wrench includes spanner
Head, locking chain and adjustment bar, the driving end middle part are equipped with threaded hole, and the both ends of the locking chain are both connected to driving end
Upper and tie point is located at the right and left of the threaded hole, so that being formed can be placed on wait pull the annular sky on nut
Between, the head of the adjustment bar is inserted in the threaded hole and is threadedly engaged between driving end, the head of the adjustment bar
Through the threaded hole out and protrude into the annular space to press in the side of nut to be pulled.
Monkey wrench as described above, the locking chain includes multiple open links.
Monkey wrench as described above, the cross-sectional shape of the open link are rectangular, so that locking chain with
It is closer wait pull the fitting between nut, it prevents from skidding, is conducive to promotion locking chain and treats the clamping dynamics for pulling nut.
The dimensions of monkey wrench as described above, each open link is identical or different, by using not
Open link with dimensions enables locking chain preferably to match the nut to be pulled of different dimensions or shape.
Monkey wrench as described above, the right and left that the threaded hole is located on the driving end are respectively equipped with connection
The both ends in hole, the locking chain are connect with the connecting hole for being located at the threaded hole left side and the right respectively.
Monkey wrench as described above further includes having handle, it is described adjustment bar tail portion through go out the threaded hole and with
Handle connection.
Compared with prior art, the spanner of the utility model can reach following effect: the locking chain of the utility model is logical
Two connecting holes crossed on driving end are installed, then the rate of tension of locking chain is adjusted by adjusting bar, to make locking chain
Item is matched with adjustment bar by nut clamp or release, and nut pulls handle after being clamped and can start to work；Simultaneously handle with
Bar connection is adjusted, rotating handle, which can be realized to treat, pulls nut clamp or release；Locking chain is made of multiple open links,
The installation number of open link can be voluntarily adjusted according to the size and shape of nut size, the utility model structure is simple, convenient
The advantages that disassembly and collection have easy processing, at low cost, and use scope is wide.
[Detailed description of the invention]
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is the working drawing of the monkey wrench of the utility model.
Fig. 2 is the perspective view of driving end in Fig. 1.
[specific embodiment]
It elaborates with reference to the accompanying drawing to specific embodiment of the present utility model.
As depicted in figs. 1 and 2, a kind of monkey wrench includes driving end 1, locking chain 2 and adjustment bar 3, the spanner
First 1 middle part is equipped with threaded hole 11, and the right and left that the threaded hole 11 is located on the driving end 1 is respectively equipped with connecting hole 12,
The head and the tail both ends of the locking chain 2 connect to be formed with the connecting hole 12 for being located at 11 left side of threaded hole and the right respectively
The annular space 4 that can be placed on nut 9 to be pulled；Preferably, the locking chain 2 includes multiple open links 21, institute
It is rectangular for stating the cross-sectional shape of open link 21；The head of the adjustment bar 3 is inserted in the threaded hole 11 and and spanner
It is threadedly engaged between first 1, the head of the adjustment bar 3 through the threaded hole 11 out and is protruded into the annular space 4 with top
It is pressed on the side of nut 9 to be pulled, the tail portion of the adjustment bar 3 is connect through the threaded hole 11 out and with handle 5.
