Abstract

Disclosed is a quick clamping spanner which has the function of a ratchet wheel and comprises a handle, a quick clamping tension spring, a quick opening push button, a fixed spanner jaw, a moveable spanner jaw and a switching bolt. A step is arranged at the lower part of the front end of the handle. The switching bolt is installed at the lower end of the fixed spanner jaw and is contacted and connected with the lower part of the front end of the handle. The quick clamping spanner which has the function of a ratchet wheel is unique in design and simple in structure. When in use, the moveable spanner jaw can be opened quickly only by dialing the quick opening push button with the fingers, and the moveable spanner jaw can be automatically clamped when the fingers are released. When the handle exerts downward force, the moveable spanner jaw can mesh with the handle. When the handle exerts upward force, the moveable spanner jaw can disengage with the handle, and the quick clamping spanner can be used as a normal spanner and has the function of a ratchet wheel. When the switching bolt is screwed down, the front end of the bolt rests against the step at the lower part of the handle to make the handle fail to actuate the function of the ratchet wheel. In this way, the ratchet wheel spanner is turned to be a moveable spanner.

Description

Fast clamp wrench with ratcher function

Technical field

The utility model relates to a kind of hand-held tool, particularly a kind of fast clamp wrench with ratcher function.

Background technology

The fast clamp wrench of prior art generally comprises the handle that fuses and fixedly pulls mouth, Flexible spanner mouth, and its Flexible spanner mouth is installed on the fixed head mouth and can moves along fixedly pulling mouth by bearing pin and turbine.Opening of the Flexible spanner mouth of this fast clamp wrench spent and can only just can be regulated by worm gear, and do not have ratcher function, so operating efficiency is very low.

The utility model content

The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of fast clamp wrench with ratcher function is provided.

The purpose of this utility model is achieved in that a kind of fast clamp wrench with ratcher function, comprise handle, the extension spring of fast folder, open push button soon, fixedly pull mouth and Flexible spanner mouth, the extension spring of fast folder is connected fixedly pulls between mouth and the Flexible spanner mouth, the Flexible spanner mouth is installed in the slotted eye of fixedly pulling mouth, opening push button soon is connected and can drives the Flexible spanner mouth on the Flexible spanner mouth and move along the slotted eye of fixedly pulling mouth, be characterized in, the described mouth of fixedly pulling is provided with an elongated slot that is used for ccontaining handle and is communicated with the slotted eye that is used to install the Flexible spanner mouth, the front end of described handle stretch in this elongated slot with fixedly pull mouthful rotatable link to each other also can mesh with the Flexible spanner mouth link to each other; Also comprise conversion bolt, the front end bottom of described handle is provided with step, and conversion bolt is installed in fixedly to pull mouthful lower end and can conflict with the step of handle front end bottom and links to each other.

The front portion of described handle is provided with a fixing hole and a mounting hole, and two pins pass fixing hole and mounting hole respectively handle mouthful is linked to each other with fixedly pulling, and one of them pin can move along mounting hole along with the rotation of handle.

The corresponding surface of described Flexible spanner mouth and handle is provided with adaptive tooth bar mutually, and the Flexible spanner mouth linked to each other with engagement when handle was exerted oneself downwards, and Flexible spanner mouth handle broke away from mutually when handle was upwards exerted oneself.

The fast clamp wrench that the utlity model has ratcher function is skillfully constructed, and is simple in structure, during use, only needs finger to stir to open push button soon just can open the Flexible spanner mouth fast, and the finger pine is next just to clamp the Flexible spanner mouth automatically.The Flexible spanner mouth linked to each other with engagement when handle was exerted oneself downwards, and Flexible spanner mouth and handle broke away from mutually when handle was upwards exerted oneself, and can make spanner and normally use, and have ratcher function.After conversion bolt screwed, bolt front end and handle lower step were inconsistent, made handle can't form ratcher function, and ratchet spanner changes monkey wrench into.
