Abstract

The utility model discloses an improvement invention of a socket wrench, which is characterized in that another one scalable small inner hexagonal socket is further arranged in a cavity of an outer inner hexagonal socket, the bottom portion of the small inner hexagonal socket is provided with a return spring, the cylinder wall of the small inner hexagonal socket is provided with a pull rod, the cylinder wall of the outer inner hexagonal socket is provided with a card slot, and the pull rod is matched with the card slot. Because another one small inner hexagonal socket is arranged in the outerinner hexagonal socket, when a fastener is small, the small inner hexagonal socket is used, if the fastener is a big fastener, the outer inner hexagonal socket is used to operate, thereby achieving the purpose of using a socket wrench to use two sizes of fasteners, saving the time of replacing the socket for operators, and also saving the cost. Compared with the prior art, the socket wrench has substantive characteristics and advance.

Description

A kind of box spanner
Technical field:
The utility model relates to a kind of improvement invention of box spanner.
Background technology:
In the prior art, hexagonal socket wrench nearly all is a kind of box spanner of specification in outer, in the time will unclamping the securing member of different size, will correspondingly change the outer interior hexagonal socket wrench of different size, though this has just increased cost undoubtedly and has reduced operating efficiency. such box spanner is arranged in front, and sleeve can be changed, but, a sleeved chest to be arranged specially, the problem of trouble so also can occur carrying, sometimes change sleeve and frequently also sleeve can be omitted in construction place.
Summary of the invention:
Given this, the technical problem that the utility model solved is for a kind of simplicity of design is provided, rational in infrastructure, can need only the box spanner that box spanner just can be realized to the securing member of two kinds of different sizes. effectively to overcome the deficiencies in the prior art, the utility model is finished as follows: this kind box spanner, include wrenching bar, spanner handle and outer interior Hexagonal jacket, described spanner handle one end connects spanner handle, the other end connects outer interior Hexagonal jacket, it is characterized in that described also be provided with in the die cavity of Hexagonal jacket in outer one telescopic another little in Hexagonal jacket, the bottom of described little interior Hexagonal jacket is provided with back-moving spring, described little interior Hexagonal jacket barrel is provided with a pull bar, described outer interior Hexagonal jacket barrel is provided with a draw-in groove, and described pull bar matches with draw-in groove.
Described pull bar is fitted with a draw ring.
The utility model is owing to be provided with another little interior Hexagonal jacket in the Hexagonal jacket outside, when securing member less, then use little interior Hexagonal jacket, if securing member is big securing member, then with Hexagonal jacket retraction in little, Hexagonal jacket in little is stuck on the barrel of outer interior Hexagonal jacket, so just can operate securing member with Hexagonal jacket in outer, realized a box spanner, carry out the purpose that two kinds of specification securing members use, save the operator and changed the time of sleeve, and also saved cost. compared with prior art, have substantive distinguishing features and progress.
Description of drawings:
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structure cutaway view of the present utility model;
Fig. 3 is the utility model side view;
Fig. 4 is the utility model STRUCTURE DECOMPOSITION figure.
The specific embodiment:
Accompanying drawing has been represented structure of the present utility model and embodiment, further describes each relevant details and operation principle thereof of embodiment below in conjunction with accompanying drawing.
In conjunction with the accompanying drawings 1, this kind box spanner, include wrenching bar, spanner handle and outer interior Hexagonal jacket, described spanner handle one end connects spanner handle, the other end connects outer interior Hexagonal jacket, also be provided with telescopic another little interior Hexagonal jacket 1 in outer in the die cavity of Hexagonal jacket 4, the bottom of described little interior Hexagonal jacket 1 is provided with back-moving spring 3, described little interior Hexagonal jacket 1 barrel is provided with a pull bar 5, described outer interior Hexagonal jacket barrel is provided with a draw-in groove 6, described pull bar 5 matches with draw-in groove 6. and the body of rod of pull bar can move in draw-in groove and the location, and described pull bar is fitted with a draw ring 2. these draw rings can make the convenient use of operator.
The utility model is owing to be provided with another little interior Hexagonal jacket in the Hexagonal jacket outside, when securing member less, then use little interior Hexagonal jacket, if securing member is big securing member, then with Hexagonal jacket retraction in little, Hexagonal jacket in little is stuck on the barrel of outer interior Hexagonal jacket, so just can operate securing member with Hexagonal jacket in outer, realized a box spanner, carry out the purpose that two kinds of specification securing members use, save the operator and changed the time of sleeve, and also saved cost. compared with prior art, have substantive distinguishing features and progress.
