Abstract
The utility model discloses a multipurpose bolt spanner. It includes the spanner left arm, upper right arm of spanner and spanner right side underarm, be provided with curved guide slot on the upper right arm of spanner, spanner right side underarm is installed in the guide slot through the round pin axle, it holds the cavity of treating the dismouting bolt to form between first section of the spanner left arm and the upper right arm of spanner, first section outside of spanner right side underarm is provided with the arc dog, the outside of the upper right arm of spanner is provided with the arc surface that suits with the arc dog, the upper right arm of spanner can move under arc dog spacing and can lead through the round pin axle. After adopting foretell structure, satisfied different diameter specifications and treated that the fastening of dismouting bolt or the demand of loosening and the adjusting range is big, have enlarged application range, reliability of positioning, clamping -force is big, has improved the reliability of using, and its structural design is reasonable, and low in manufacturing cost is applied more extensive, uses more convenient and fast, has saved a large amount of operating time, and the operating is simplified process has improved work efficiency.
Description
Technical field
The utility model is related to a kind of bolt and nut dismounting instrument, specifically a kind of multipurpose track wrench.
Background technology
With the development of China's science and technology, the renewal of various use instruments is also strengthened therewith, particularly some simple structures, warp
The instrument that uses of Ji is generally adopted and uses, especially for spanner for, in order to be applicable different demands, existing spanner
Specification is also diversified, and later in the market has engendered the spanner of some adjustable jaw sizes, and such spanner meets
Different-diameter bolt removes and installs requirement, but generally existing complex structure, using inconvenience and it is more expensive to manufacture, press from both sides
Holding force is small and uses the variety of problems such as poor reliability.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of simple structure, convenient to use, and chucking power is big, can
It is good by property, the multipurpose track wrench of low cost of manufacture.
In order to solve the above-mentioned technical problem, multipurpose track wrench of the present utility model, including spanner left arm, by being hinged
Spanner right upper arm and arc can be provided with spanner right upper arm with the spanner bottom right arm of spanner right upper arm cooperation that axle is hinged
Guide groove, spanner bottom right arm by bearing pin be arranged on guide groove in and can be moved back and forth in guide groove, the upper semisection of spanner left arm
The cavity for accommodating and treating assembling-disassembling bolt is formed between spanner right upper arm, the upper semisection outside of spanner bottom right arm is provided with arc gear
Block, is provided with the curved surfaces being adapted with block arc on the outside of spanner right upper arm, spanner right upper arm can be in block arc
Spacing lower movement and can be oriented to by bearing pin.
The upper semisection of the bearing pin is provided with thread segment, and spanner bottom right arm can be fastened by fastening bolt.
The spanner left arm includes two sections, and its epimere has the interior table being adapted with bolt outer contour shape to be removed
Face, its hypomere have oliquely downward incline handle.
Spanner bottom right arm is fixedly installed with bearing pin and is integrated.
It is provided with just to the sawtooth on the inside of spanner left arm on the inside of the spanner right upper arm or/and hand bottom right arm upper semisection.
After using above-mentioned structure, due to the spanner bottom right arm installed by guide groove for setting, the upper semisection of spanner left arm
The cavity for accommodating and treating assembling-disassembling bolt is formed between spanner right upper arm, thus not only can be with pine or tight bolt and nut, can also root
The size of spanner and position adjustments jaw of spanner of the underarm in guide groove is adjusted according to the diameter for treating assembling-disassembling bolt, is met not
With diameter specifications treat assembling-disassembling bolt to tighten or loosen demand and adjusting range big, expand and use scope, spanner is right in addition
The block arc that the upper semisection outside of underarm is set, spanner right upper arm in the spacing lower movement of block arc and be able to can pass through
Bearing pin is oriented to so that reliability of positioning, and chucking power is big, improves the reliability for using, and its reasonable in design is manufactured into
This is low, and one instead of multiple spanners spanner, using more extensively, using more convenient and quicker, saves the substantial amounts of operating time, letter
Change operating process, improve operating efficiency.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model multipurpose track wrench；
Fig. 2 is spanner right upper arm and spanner bottom right arm installment state structural representation in the utility model.
Specific embodiment
With reference to the accompanying drawings and detailed description, multipurpose track wrench of the present utility model is made further specifically
It is bright.
As illustrated, multipurpose track wrench of the present utility model, including spanner left arm 1, it is left by jointed shaft 2 and spanner
Spanner right upper arm 3 and can be provided with spanner right upper arm 3 with the spanner bottom right arm 6 of spanner right upper arm cooperation that arm 1 is hinged
The guide groove of arc, spanner bottom right arm 6 is arranged in guide groove and can be moved back and forth in guide groove by bearing pin 5, spanner left arm 1
The cavity for accommodating and treating assembling-disassembling bolt 8 is formed between upper semisection and spanner right upper arm 3, the upper semisection outside of spanner bottom right arm 6 is set
There is block arc 4, the outside of spanner right upper arm 3 is provided with the curved surfaces being adapted with block arc 4, the energy of spanner right upper arm 3
Reach the spacing lower movement in block arc 4 and can be oriented to by bearing pin 5.
Further, the upper semisection of described bearing pin 5 is provided with thread segment, and spanner bottom right arm 6 can be by fastening bolt 7
Fastening, spanner bottom right arm 6 is fixedly installed with bearing pin 5 and is integrated, and spanner left arm 1 includes two sections, and its epimere has and waits to tear open
Unload the adaptable inner surface of bolt outer contour shape, its hypomere has and oliquely downward inclines handle.
