Hammer hits the oil siren connection tool

HU series wrenches are used to hammer the oil siren connection, 

and the design patent is currently under application.

The method of turning the connection point by tapping the hammer is outdated, 

and using the HU series wrench,

 the operator no longer holds the hammer,

 thus making the operation safer.The series of wrenches comes in two different models for all standard specifications.

The product uses easy lock head for installation and setting;

 the product performs spring movement almost without manual operation.
