Abstract

The utility model relates to an auxiliary device for a hexagon wrench. A nesting end and a handle receiving end are respectively formed at both ends of a body, wherein more than two nesting holes are concavely arranged in the center and the periphery of the end face of the nesting end, and an extending handle extends out from the handle receiving end and connected with a dismountable grip. Therefore, the auxiliary device for the hexagon wrench can be nested on a torsional handle of the hexagon wrench so as to cause a force applying handle to extend deeply into a machine platform to dismount screws, and simultaneously prolong the length of the torsional handle; and the auxiliary device leads the hexagon wrench to be conveniently held, prolongs the force applying handle and enhances the moment of force generated by force application, thus achieving the purposes of convenient holding and easy force application for pulling.

Description

The die nut servicing unit

Technical field

The utility model relates to a kind of aid, relates in particular to a kind of die nut servicing unit of extensible torque of wrenches handle length.

Background technology

General common die nut group, see also Fig. 4, it includes the die nut 40 of some different sizes, each die nut 40 slightly is the one-body molded body of rod of L type, and include the arm of force than a long effort handle 41, and the short torsion handle 42 of the arm of force, then be formed with section respectively in effort handle 41 ends and torsion handle 42 ends and be hexagonal shrink-fit structure.

When die nut 40 uses under general state, normally utilize torsion handle 42 ends to be socketed on the screw of desiring to screw or unscrew, switching effort handle 41 is to screw or to unscrew screw again, because effort handle 41 has long force arm, therefore, be easy to generate bigger moment, to reach the labour-saving effect.

The screw of desiring to screw or unscrew when die nut 40 is that the position is when being arranged in board depths or gap, at this moment, then need utilize the long effort handle 41 of die nut 40 to stretch into board depths or gap, shrink-fit structure socket screw with effort handle 41, again by switching torsion handle 42 rotary screws, to reach the purpose that screws or unscrew screw.

Yet, because torsion handle 42 arm of forces of die nut 40 are shorter, therefore, not only be not easy to grip and switching when the application of force, the moment that is produced is also less relatively, and is easy to generate the moment deficiency, the problem that is difficult to rotation screw also can't reach the labour-saving effect effectively.

Summary of the invention

For having, the torsion handle that solves existing die nut is not easy to grip and switching, and be easy to generate the moment deficiency, and be difficult to the problem of rotation screw, for solving aforesaid problem, main purpose of the present utility model is to provide a kind of die nut servicing unit of assisting switching torsion handle, makes things convenient for switching torsion handle to reach, and prolongation torsion handle length, to increase the purpose of the moment that the application of force was produced, for reaching aforesaid purpose, technological means of the present utility model such as following.

The utility model realizes that the technical scheme that purpose adopts is to propose a kind of die nut servicing unit, it is characterized in that having a body, and be formed with a fit end and respectively in the two ends of body and connect pommel, wherein, the fit end is concaved with the register hole of two above different sizes on end face, connect pommel and then extend an extension stem by end face.

Described die nut servicing unit, wherein:

Aforesaid plural register hole is rounded hole respectively.

Described die nut servicing unit, wherein:

Aforesaid body is to be cylindric;

Aforesaid two above register holes are distributed in the end face center of fit end respectively and are distributed in around the end face in the form of a ring.

Described die nut servicing unit wherein further connects a removable handle on the extension stem of body.

Described die nut servicing unit, wherein extension stem is formed with an engagement recess on outer peripheral face; Removable handle includes an axis body, is formed with a handle portion on axis body, then is provided with an engaging element in the axis body front end, is engaged on the engaging piece of extension stem.

The utility model compared with prior art has tangible advantage and beneficial effect, comprising:

1. die nut servicing unit of the present utility model can be socketed on the torsion handle of die nut, make effort handle can stretch into board depths dismounting screw, and the length of extending the torsion handle grips with convenient, and prolongs the total length of force arm, and can increase the moment that the application of force produces.

2. die nut servicing unit of the present utility model can further connect a removable handle, significantly increasing force arm length, and reaches convenient and grips and the light purpose of the application of force.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.

The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
