Description
Technical field
It the utility model is related to hardware ＆ tools field, and in particular to a kind of ratchet spanner.
Background technology
Ratchet spanner has turned into a kind of widely used Wrench in the whole world, and its head has a ratchet device to pass through
The plectrum control spanner of outside is placed on only to the left or only to the right, just because of having this ratchet device so operator is not when in use
Need to repeat to extract to load such action, so being widely used.For example, the space of automotive engine compartment is very compact.Cause
This, bolt tightening operation is restricted, and the spanner for tightening or unclamping bolt is possible can only be in spanner and engine nacelle
Other elements contact or interference before Small-angle Rotation.It is usually very clumsy using conventional tool (non-ratchet) in these spaces
And difficulty, because this requires Small-angle Rotation, then remove, then again engage instrument and bolt or other workpiece.Therefore, spine
Wheel instrument is advantageous in that it is remained engaged with, and substantially saves time and strength compared with traditional non-ratchet tool.
But in existing ratchet spanner, the Bolt dismantling of small size is applied in general to, it is bigger for torque, such as
During more than 500N.m bolt fastening, typically bolt is fastened using common wrench (non-ratchet), but common wrench (non-spine
Wheel) efficiency it is very low, also with attempting using ratchet spanner, but because complicated, such as patent
A kind of high-torque ratchet wrench that CN201120184891.2 is provided, it uses eccentric structure, manufacture and its complicated, cost compared with
It is high.
Utility model content
In order to solve the problems, such as the ratchet wrench structure complexity of existing fastening high torch bolt, the utility model provides a kind of
Ratchet spanner.
The utility model is achieved by the following technical solution：A kind of ratchet spanner, including base, end cap and connection
Bar, ratchet and pawl is provided with base, ratchet is arranged on inside the endoporus of base vertical direction, and the ratchet matched with ratchet is set
In horizontal direction through hole on the right side of bottom set seat；The right-hand member of base is connected with connecting rod, and in the horizontal direction in through hole ratchet end
End is provided with stage clip；Ratchet is internally provided with fastener connecting hole, and ratchet is provided at both ends with multi-diameter shaft, lower end multi-diameter shaft with
The endoporus of base vertical direction matches, and upper end multi-diameter shaft matches with end cap, and the end cap is connected by bolt assembly and base
Connect.
Further, the connecting rod end is connected with arm strength bar.
Beneficial effect caused by a kind of ratchet spanner of the utility model is：By setting ratchet and pawl in base, it is
It is easily installed and dismantles, ratchet is arranged on inside the endoporus of base vertical direction, and ratchet match with ratchet sets the base right side
In the horizontal direction through hole of side；Ratchet is internally provided with fastener connecting hole, is easy to be connected with fastener；The both ends of ratchet are set
Multi-diameter shaft is equipped with, lower end multi-diameter shaft matches with base endoporus, and upper end multi-diameter shaft matches with end cap, and the end cap passes through bolt
Component is connected with base, and the right-hand member of base is connected with connecting rod, and the end of ratchet is provided with stage clip in through hole in the horizontal direction；
When fastener connecting hole inside by ratchet is set on fastener, be rotatablely connected bar, you can complete fastener tighten and
Dismounting, by setting stage clip, can set the Tightening moment of fastener；Whole ratchet wrench structure is simple, easily manufactured, when more
When changing the larger spring of spring force, you can realize the fastening of high pulling torque bolt, the ratchet wrench for solving existing fastening high torch bolt
The problem of hand is complicated.
