Description
Technical Field
The utility model relates to a common tool field, in particular to spanner.
Background
The spanner usually includes spanner head and spanner arm, when using the spanner, when the locking force of bolt is great, because spanner arm's length is limited, the locking force of bolt can't be overcome to the effort that the user applyed, user's accessible increases spanner arm length and reaches laborsaving purpose, nevertheless if only increase spanner arm length, the length of overlength spanner arm leads to the spanner to be inconvenient to carry and deposit, for solving this problem, conventional technological means is that the user increases spanner arm's length with the help of instrument appurtenance such as sleeve pipe, reduce the dismantlement degree of difficulty of bolt according to this, but the sleeve pipe is lost easily, it is inconvenient to use.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims to provide a spanner, spanner arm have set firmly joint portion, and two spanner arms link firmly through respective joint portion joint, reach the purpose of extension spanner arm under the prerequisite that need not with the help of appurtenance, eliminate appurtenance and carry inconvenient problem, and it is more convenient to use.
The utility model provides a wrench, including the spanner arm, the tip of spanner arm has set firmly joint portion, and two arbitrary spanner arms link firmly through the joint portion joint that establishes separately.
Preferably, the clamping portion comprises a plurality of clamping teeth which are radially and uniformly distributed.
Preferably, the clamping groove between any two adjacent clamping teeth is matched with the clamping teeth.
Preferably, any snap tooth is sector arc shaped.
Preferably, the clamping portion is integrally arranged on the wrench arm.
Preferably, the end of the wrench arm is provided with a hook hole, and the hook hole is coaxially communicated with the avoiding groove arranged in the center of the clamping part.
For the background art, the utility model provides a spanner, including the spanner arm, the tip of spanner arm is equipped with joint portion, during the use, utilizes a spanner chucking to treat the dismantlement bolt, holds another spanner again, and the butt joint of the tip of the spanner arm of two spanners makes the joint portion joint of two spanner arms again, and two spanner arms link firmly through respective joint portion joint, and the spanner arm obtains the extension, reaches the purpose of dismantling the bolt laborsavingly, need not to borrow auxiliary tool such as sleeve again to assist the spanner to dismantle the bolt, and it is more convenient to use.
