Description
Technical field
The utility model relates to a kind of spanner that is exclusively used in wall fastened by screw.
Background technology
On body of wall in fixed screw or nut, conventionally need to use spanner, because needs screw screw or nut, therefore screw or nut need to be threaded to surface of wall and fit, existing spanner, is carrying out this class screw or nut when fastening, and itself and wall surface fit, therefore human hands is difficult to the application of force, has caused installing comparatively difficulty.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of spanner that is exclusively used in wall fastened by screw, and the use of this device is convenient to, to the screwing of the screw on body of wall or nut, facilitate the hand application of force.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of spanner that is exclusively used in wall fastened by screw, comprise wrenching bar, and be arranged on the driving end of wrenching bar left end, also comprise force application rod and sliding assembly, the right-hand member of described wrenching bar is provided with the recess of a U-shaped, the left end of described force application rod is provided with connecting portion, described connecting portion is engaged in described recess, and and between recess, be connected with rotating shaft, described sliding assembly is provided with three, two described sliding assemblies are arranged on described wrenching bar near that end of driving end, these two sliding assemblies are symmetrical arranged centered by wrenching bar, described in one of them, sliding assembly is arranged on that one end of described connecting portion face phase recess, described sliding assembly comprises base, spheroid and capping, after coordinating, described base and capping form a cavity that holds spheroid, described capping has a through hole communicating with cavity, the aperture of this through hole is less than the sphere diameter of spheroid, after described spheroid is engaged in cavity, the upper surface of spheroid extends to capping outside by through hole.
As preferred technical scheme, described wrenching bar and driving end are integral type.
As preferred technical scheme, on described wrenching bar, be arranged with an Anti-slip cover, the thickness of described Anti-slip cover is less than the sphere diameter of spheroid.
As preferred technical scheme, the right-hand member of described force application rod is provided with a link, and described link and force application rod are integral type.
The beneficial effects of the utility model are: when the screw on fixing body of wall or nut, first in a conventional manner screw or nut are screwed into a certain degree, when the inconvenient application of force of hand, only force application rod need to be bent, the force application rod that is is vertical with wrenching bar, at this moment, utilize contacting of spheroid and metope, reduce the frictional force of wrenching bar and metope, by forcing in force application rod, can be rotated wrenching bar, conveniently screw this class screw or nut, the structure of this device is comparatively simple simultaneously, is applicable to promoting the use of.
