Abstract
The utility model belongs to machine tool technical field, relates to a kind of spanner, and comprise Handheld Division, rotating handles, wrenching bar, connector and nut head or driver bit, Handheld Division is connected by bearing with wrenching bar, and wrenching bar and Handheld Division can relatively rotate; Rotating handles is Contraband shape, and rotating handles is fixedly connected with wrenching bar; Connector is connected with wrenching bar end winding support, and connector and nut head or driver bit are dismountable grafting; Be applicable to the installation and removal of narrow range inner nut or screw, apply pressure by Handheld Division, make nut head or driver bit and nut or screw close contact, can avoid occurring stripped thread phenomenon; Simultaneously Contraband shape rotating handles increases moment, can easily installing/dismounting nut or screw, is applicable to the use of the less crowd of strength.
Description
Technical field
The utility model belongs to machine tool technical field, specifically, relates to a kind of spanner being applicable to privileged sites clamp nut or screw installation and removal.
Background technology
Spanner is a kind of conventional installation and removal instrument, utilizes lever principle to twist the fastened tools such as bolt, screw or nut.Spanner is usually provided with Handheld Division at shank and applies external force, can twist opening or trepanning that bolt or nut hold bolt or nut.But existing Wrench is when rotating or be tightened in the nut at narrow scope place, space, usually effort is compared, installation personnel is other instruments such as choice for use clamp sometimes, because contact surface is misfitted, nut local pressure, easily cause the damage of nut layer structure, outer surface stripped thread phenomenon occurs, causes nut to dismantle; Meanwhile, existing spanner, when dismantling screw, cannot apply pressure at right angle, be not suitable for the less personnel of strength especially, the use of such as children or Ms.
Utility model content
The purpose of this utility model is to overcome the shortcoming that prior art exists, and seeks to design a kind of end removable, can installing/dismounting nut, screw multifunctional wrench, be applicable to the operation of instrument in narrow range, be applicable to the use of the less crowd of strength.
To achieve these goals, the technical solution adopted in the utility model is: a kind of spanner, comprise Handheld Division, rotating handles, wrenching bar, connector and nut head or driver bit, described Handheld Division is connected by bearing with wrenching bar, and wrenching bar and Handheld Division can relatively rotate; Described rotating handles is Contraband shape, and rotating handles is fixedly connected with wrenching bar; Described connector is connected with wrenching bar end winding support, and described connector and nut head or driver bit are dismountable grafting.
Preferably, described connector inside is interior anise or interior hexagonal structure; The link of described nut head or driver bit is outer anise or outer-hexagonal, coordinates with connector.
The beneficial effects of the utility model are: the installation and removal being applicable to narrow range inner nut or screw, after changing suitable nut head or driver bit, apply pressure by Handheld Division, make nut head or driver bit and nut or screw close contact, can avoid occurring stripped thread phenomenon; Simultaneously Contraband shape rotating handles increases moment, can easily installing/dismounting nut or screw, is applicable to the use of the less crowd of strength.
