Abstract
The utility model discloses a kind of ratchet spanner, it is provided with the ratchet (2) of installing hole (3) including connecting rod (1) and centre, described ratchet (3) interlocking is in one end of connecting rod (1)；It is characterized in that：The lateral wall of described ratchet (2) is provided with boss (4), and described boss (4) is rabbeted in connecting rod (1).After this structure, provide a kind of avoid ratchet to rotate against at the place of inlaying of connecting rod, and improve the structural strength of the junction of connecting rod and ratchet, thus the high ratchet spanner of structural strength.
Description
Technical field
This utility model is related to spanner technical field and in particular to a kind of ratchet spanner.
Background technology
At present, ratchet spanner can easily dismount screw, and the connector of bolt is thus be widely used.
Traditional, ratchet spanner generally comprises metal link rod and ratchet, and ratchet is located at the one end in connecting rod, this structure
Ratchet spanner has larger outputting torsion and structural strength, but there is also following deficiency, and one is heavier mass, and two is that metal connects
Bar manufacturing cost is higher, three be ratchet be to be arranged on metal link rod by mounting structure, metal link rod must be provided with pacify
Assembling structure, causes complex manufacturing.
Then, market is just to occur in that the ratchet spanner replacing metal link rod with plastic rod, and ratchet is embedded in connecting rod
One end, ratchet is convenient for production with connecting rod, but said structure yet suffers from certain deficiency：When the twisting resistance that ratchet is subject to is larger
When, on the one hand because ratchet is embedded in connecting rod one end, easily cause ratchet and rotate with respect to inlaying place, cause ratchet wrench
Handss lost efficacy；On the other hand, because connecting rod is plastic, cause that plastic rod is incident with the junction of ratchet to fracture, cause
Make ratchet spanner damage inactivation.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind of avoids ratchet to occur relatively at the place of inlaying of connecting rod
Rotation, and improve the structural strength of connecting rod and the junction of ratchet, thus the high ratchet spanner of structural strength.
For solving above-mentioned technical problem, ratchet spanner of the present utility model, it is provided with the spine of installing hole including connecting rod and centre
Wheel, described ratchet is rabbeted in one end of connecting rod；The lateral wall of described ratchet is provided with boss, and described boss is rabbeted in connecting rod
Interior.
After above structure, this utility model compared with prior art, has advantages below：Lateral wall due to ratchet
It is provided with boss, described boss is rabbeted in connecting rod, and so, boss is mutually chimeric with connecting rod, boss increased even
Bar is in the structural strength of junction, it is to avoid ratchet rotates against at the place of inlaying of connecting rod, and improves connecting rod and ratchet
The structural strength of junction, thus the high ratchet spanner of structural strength.
Preferably, the side wall of described boss is provided with groove.The presence of groove, on the one hand serve positioning boss with
The effect of the interlocking point of connecting rod, on the other hand playing increases the contact area of boss and connecting rod, improves boss and connecting rod
Chimeric degree, improves the stability of product further.
Preferably, the top of described boss is provided with recess.The presence of recess, on the one hand serves positioning boss and company
The effect of the interlocking point of bar, on the other hand plays and increases the contact area of boss and connecting rod, and raising boss is embedding with connecting rod
Right, improve the stability of product further.
Preferably, described connecting rod is linear type, corresponding, and boss is the linear type of the length direction extension along connecting rod.
Certainly, the structure of connecting rod can also be as follows：Described connecting rod include being sequentially connected by ratchet one end to the other end
One straightway, bending segment and second straight line section, corresponding, described boss by bottom to top include successively first straight line portion,
Kink and second straight line portion, first straight line portion rabbets in first straight line section, and kink is rabbeted in bending segment, second straight line
Portion rabbets in second straight line section.So, at the screw that connecting rod is twisted with respect to need, there is certain altitude, the spiral shell that need to twist can be prevented
Periphery material at nail hinders the work space of ratchet spanner so as to use more convenient.
Preferably, described kink and the angle of ratchet end face are 10 °～60 °.
Preferably, the outer circumference surface of described ratchet is provided with a plurality of groove, and described groove extends in the axial direction.So,
The presence of groove, on the one hand serves the effect of positioning boss and the interlocking point of connecting rod, on the other hand plays increase boss
With the contact area of connecting rod, improve the chimeric degree of boss and connecting rod, improve the stability of product further.

Specific embodiment
With reference to the accompanying drawings and detailed description utility model is described in more detail.
Referring to accompanying drawing 1 to shown in accompanying drawing 5, a kind of ratchet spanner, it is provided with the ratchet 2 of installing hole 3 including connecting rod 1 and centre,
Described ratchet 2 is rabbeted in one end of connecting rod 1；The lateral wall of described ratchet 2 is provided with boss 4, and described boss 4 is rabbeted even
In bar 1.
The side wall of described boss 4 is provided with groove 5.
The top of described boss 4 is provided with recess 6.
Described connecting rod 1 is linear type, corresponding, and boss 4 is the linear type of the length direction extension along connecting rod 1.
The outer circumference surface of described ratchet 2 is provided with a plurality of groove 7, and described groove 7 extends in the axial direction.
Certainly, as Fig. 4 and Fig. 5, the structure of connecting rod can also be as follows：Described connecting rod 1 is included to the other end by ratchet 2 one end
