Abstract

The invention provides a monkey wrench, which mainly comprises a handle, a movable jaw and two gear blocks. Two accommodating holes for accommodating the two gear blocks are opened in the head part of the handle, and the two gear blocks can move toward the direction near to or far away from the movable jaw in the accommodating holes. Two rows of gear parts are arranged on two sides of the bottom edge of the guiding part of the movable jaws, the gear surface of the two gear blocks can be used to be engaged or disengaged with the corresponding matched gear parts and a positioning part is arranged between the gear blocks and the accommodating holes. Each gear block can be independently controlled through the positioning part which enables the gear blocks to engage at any time or to disengage for all time with the gear parts.

Description

Monkey wrench

Technical field

The present invention relates to the hand-held tool field, refer to a kind of monkey wrench especially.

Background technology

In the industrial hand-held tool that is usually used in rotating screw cap, You Yike adjusts the monkey wrench of folder mouthful size arbitrarily for first-selected, this traditional monkey wrench utilizes rotary worm to adjust the folder mouth size of movable jaw, because it is all gapped between the flank of flank of worm screw and movable jaw, make its binding nut when adjusting movable jaw, and take out after driving first circulation, this moment, the gap can make folder mouthful size decreases, circulate and can't promptly be inserted in, drive second once more, not only bring inconvenience, and to adjust the movable jaw position very time-consuming again because of rotary worm, obviously not good on service efficiency.

Problem for this reason, shown in United States Patent (USP) case US1523093 number, to establish containing hole in the wrench head in this case, can insert for two tooth pieces, the flank of tooth of two tooth pieces is staggered, and can make one of them tooth piece mesh the movable jaw tooth bar, another tooth piece then is disengaged position, and when stirring operating portion, two tooth pieces are separated with tooth bar, can adjust the size of movable jaw and fixed jaw.

But, this case is only established single tooth bar at the root edge of the round bar of movable jaw, therefore only can be used in the tooth pitch adjustment of single size, this is in public affairs, securing member (Fasteners) made in Great Britain and the country (for example U.S.) that deposits, to cause the user must buy each one of public affairs, English unit (Metric, SAE) simultaneously, make the user pay ancillary cost virtually, and need seek in the use, differentiate, all very inconvenient; For this reason, the inventor is demand especially according to this, and design a monkey wrench that can use simultaneously at the securing member (Fasteners) of metric unit and English unit, as Chinese application case number No. 200710188137.4, in addition, more exquisite and accurate for asking this design, allow the user on same monkey wrench, can freely select metric unit or English unit according to the not commensurate demand of securing member (Fasteners); Therefore, the invention provides innovative monkey wrench described in hereinafter detailed description.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of simple, maneuverable monkey wrench, it can use according to the not commensurate demand of securing member.

For achieving the above object, the invention provides a kind of monkey wrench, mainly comprise:

Lever, this lever one end is provided with head, and this head is extended with fixed jaw, and head is provided with the containing hole of chute and connection chute;

Movable jaw, an end has guidance part, and this guidance part root edge has two toothrow portions, and movable jaw is located in the chute with this guidance part;

Two tooth pieces are arranged at the opening both sides of containing hole respectively, and this tooth piece forms the flank of tooth near the surface of tooth portion; Wherein, be provided with the location division between tooth piece and the containing hole, this location division control tooth piece is in primary importance and tooth portion meshes or control tooth piece is separated in the second place and tooth portion.

Monkey wrench of the present invention has the toothrow portion and the tooth piece of two kinds of different tooth pitches (Pitch), tooth pitch is a kind of to be metric unit, another kind is an English unit, can make this monkey wrench, can be applied to the securing member (Fasteners) of metric system and English unit simultaneously, and between tooth piece and containing hole, be provided with the location division, this location division can independently respectively control this metric system or tooth piece made in Great Britain is positioned and can meshes at any time, or break away from this tooth portion forever, to allow the user reach simple, maneuverable effect according to the not commensurate of securing member.Comprehensively above-mentioned, the present invention relends by the location division, can independently control the tooth piece of variant unit, can allow the user can comply with the not securing member of commensurate really, reaches to save time, save money, again can simple, maneuverable effect.
