Abstract
The utility model discloses a double head spanner, which comprises two open heads of similar specifications arranged at both ends and a middle handle, wherein, one opening surface of each open head is vertically distributed with two working faces to form two openings of similar specifications. Due to one surface of each opening of the spanner being vertically distributed with two working faces to make one head of the spanner form into two bayonets of similar specifications for matching with nuts or bolts of two specifications, one double head spanner of the above structure is equivalent to two ordinary double head spanners and can match with nuts or bolts of four specifications, thereby greatly improving work efficiency and realizing more convenient carryover and much less replacement time of tool for people engaged in mobile operation and aloft work in particular.
Description
Technical field
The utility model relates to a kind of hand-operated tools, especially a kind of double (end) wrench.
Background technology
The double (end) wrench of the both ends open that generally uses can only work to two kinds of specifications of nuts or bolt at present, needs often to change the spanner of different size during work, brings many inconvenience to the operator, also influences operating efficiency.
The utility model content
The purpose of this utility model provides the double (end) wrench of a kind of novel structure, easy to use, high efficiency.
The technical solution of the utility model is: a kind of double (end) wrench, comprise the open type head and the mid-handle of two adjacent-specifications in two ends, and height is straggly on an opening surface of each open type head is distributed with two working faces, constitutes the opening of two adjacent-specifications.
Because two working faces of height distribution straggly on a face of each opening of spanner, make the bayonet socket of two adjacent-specifications of stature formation of spanner, can adapt to two kinds of specifications of nuts or bolt, a double (end) wrench of this structure just is equivalent to two common double (end) wrench, can adapt to the nut or the bolt of four kinds of different sizes, operating efficiency is improved greatly.Convection current action dealer, particularly work high above the ground person carry the convenient time that can reduce the replacing instrument again.
