Description
Technical field
The utility model belongs to machine tool technical field, relates to a kind of mechanical wrench.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut, and spanner is usually with carbon structural steels or alloy structure steel making.
As Chinese utility model patent application (application number: CN200720100931.4) discloses a kind of spanner, it draws together spanner handle, wrench body and driving end, spanner handle is processed as one with wrench body, it is characterized in that: wrench body has cannelure, also has secondary spanner handle, the secondary spanner labour contractor of secondary spanner handle is arranged on cannelure, the ratchet with interior ratchet is installed in cannelure, limited location projection outside ratchet, the front limit plush copper of secondary spanner labour contractor withstands on below spacing block set, at wrench body, reset arc plate-shaped springs is installed, one end of this spring withstands on above spacing block set, the pawl axis be integrated with pawl disk is installed at wrench body, pawl axis is arranged on the axis hole of wrench body, pawl disk is arranged on inside the ratchet of ratchet, pawl disk is installed with ratchet, and ratchet is meshed with pawl teeth, has polygon prism driving end in the outer end of ratchet shaft, because spanner needs manual force in operation, the length of spanner determines the size of operating physical force, and the angle of handle determines the convenience of operation, and obviously above-mentioned wrench operated flexibility is poor.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of mechanical wrench, and this mechanical wrench can regulating handle length and position, and applicability is strong.
The purpose of this utility model realizes by following technical proposal: a kind of mechanical wrench, comprise and determine handle and driving end, described driving end is positioned at the one end of determining handle, it is characterized in that, also comprise the fixed handle of two strips, one end of this two fixed handle is all hinged on the other end determining handle, described end of determining handle offers holding tank along its length, this holding tank runs through the dual-side edge of determining handle, the end of above-mentioned two fixed handles is hinged on holding tank inside respectively, and two fixed handles all can turn in holding tank, described fixed handle and determine to be provided with between handle and fixed handle can be fixed on the keeper determined on handle.
Driving end has the connecting hole adapted with nut or bolt, all relatively can determine handle due to two fixed handles to swing, therefore when the operating physical force do not used or need is less, rotating fixed handle makes fixed handle move in holding tank, now the entire length of mechanical wrench is shorter, therefore carry convenient, and it is less to be suitable for the space needed, use more flexible, and when the operating physical force needed is larger, rotating fixed handle makes fixed handle launch and be fixed by keeper, when fixed handle with determine, when handle parallels, there is the maximum arm of force, and when there is angle between two fixed handles, this two fixed handle can be used in two grasped or two people grasp, use flexibly, applicability is strong.
In above-mentioned mechanical wrench, fixed handle described in two by hinge on relative two cell walls of holding tank, and two bearing pins along determine handle width setting.Occur mutually against catching phenomenon when avoiding two fixed handles to rotate.
In above-mentioned mechanical wrench, described keeper comprises bolt, described end of determining handle has two positioning disks, this two positioning disk lays respectively at the both sides up and down of fixed handle, on described positioning disk, circumference offers locating hole, described fixed handle offers screw, and above-mentioned bolt is screwed onto in screw through locating hole.Locating hole circumference is uniformly distributed, and bolt is through being screwed onto in screw after the locating hole of a positioning disk, and insert after being rotated through screw in the locating hole of another positioning disk, bonding strength is high.
In above-mentioned mechanical wrench, the two equal arc transition in edge of described fixed handle, and when two fixed handles are all positioned at holding tank, the edge of fixed handle seamlessly transits with the edge determining handle.The two equal arc transition in edge of fixed handle, grasping when facilitating fixed handle to launch, and the edge of fixed handle and the edge determining handle seamlessly transit, and grasp when facilitating fixed handle to be positioned at holding tank.
In above-mentioned mechanical wrench, described fixed handle lateral wall is enclosed with rubber layer, rubber layer and holding tank tight fit when fixed handle is positioned at holding tank.Rubber layer can improve grasping comfortableness, is positioned in holding tank by fixed handle simultaneously.
Compared with prior art, this mechanical wrench has the following advantages:
1, make fixed handle move in holding tank owing to rotating fixed handle, now the entire length of mechanical wrench is shorter, therefore carries convenient, and it is less to be suitable for the space needed, and uses more flexible.
2, fixed handle is made to launch and be fixed by keeper owing to rotating fixed handle, when fixed handle with determine, when handle parallels, there is the maximum arm of force, and when having angle between two fixed handles, this two fixed handle can be used in two grasped or two people grasp, use flexibly, applicability is strong.
