Description

The plug-in tool construction

Technical field

The utility model relates to a kind of hand-operated tools, relate in particular to a kind of fixedly adjustment angle of existing hand-held tool head of improving, or pulling part shortcoming such as can't replace, and reaches the effect of fixedly sleeved institute's hue angle, and replaceable pulling part and improve the plug-in tool construction of practicality.

Background technology

The current common people take action on one's own to arrange and contain the DIY general mood day in the family, add domestic hand-held tool development and have reached the quite degree of level, and its quality and structure are quite mature and stable, no matter wherein be product category or architecture quality, more win domestic and international consistent affirming.Over the years in order to make the easier in use left-hand seat of general consumption masses, so the hand-held tool of various easy operating or subsidiary hommization function is also asked the city successively.

General existing spanner is that shank part and head are arranged on the same plane, and this shank part and head are the bonding state that can not adjust angle, and this kind spanner for the position at the non-flat forms place, construction place with barrier, quite be difficult to use, the bending shape spanner that therefore in the streets has the dealer to release to be a special angle between Wrench head and shank part is so that overcome this shortcoming;

The spanner that has bending angle between this kind head and shank part is established though can stretch into the construction place switching spiral shell with barrier in use, and this angle is to be fixing and can't to adjust, and therefore still can't be applied to various occasions flexibly.

So there is the dealer to develop all kinds of hand-held tools of bent adjustment between head and the shank part, announce " hand-held tool bent angle structural improvement " patent of No. 554785 as TaiWan, China, though should existing preceding case have the effect of adjustable head and shank part luffing angle, but none effective fixed mechanism, cause this pulling part in use, the arbitrarily crooked rotation along with user's application of force direction easily, though therefore existing hand-held tool is provided with the whole structure of bendable modulation, can bring more inconvenience in the practicality.

Moreover its pulling part of existing hand-held tool is to be the state that sets firmly that can't replace to combine with shank part, the applicability of spanner is significantly reduced, so still have the shortcoming that need overcome in the design of integral body again;

Therefore as a complete unit, its poor practicability has in addition improved necessity in fact.

The utility model content

Technical problem underlying to be solved in the utility model is, overcome the above-mentioned defective that prior art exists, and provide a kind of plug-in tool construction, it can improve fixedly adjustment angle of existing hand-held tool head, or pulling part such as can't replace at shortcoming, reach the effect of fixedly sleeved institute's hue angle, and replaceable pulling part and improve practicality.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of plug-in tool construction comprises a tool body and a shank part, it is characterized in that, shank part one end of this tool body is to form storage tank, and this storage tank is pivoted for the socket part and is rotating bonding state, and this bottom, socket part is formed with tooth portion; Be provided with a retainer component in this storage tank, an end of this retainer component has the corresponding groove with tooth portion, and the storage tank bottom then is provided with one and adjusts structure, borrow this to adjust the elongation of structural adjustment retainer component and shorten, and the effect of location and socket part, deletion location is supported in the Dacca.

Aforesaid plug-in tool construction, wherein the socket part is provided with inserting port, replaces for pulling part and plants.

Aforesaid plug-in tool construction, wherein adjusting structure is an adjusting lever and an elastic component, described retainer component then is subjected to replacing of adjusting lever and stretches out with the socket part to fasten the location, and this adjusting lever is provided with groove, this adjusting lever is when stressed pushing, groove is corresponding to described retainer component, the space that makes described retainer component contract in having, and remove the location that fastens with the socket part.

Aforesaid plug-in tool construction, wherein adjusting structure is a nut, and this nut and described retainer component spiral shell are established, and it is flexible to adjust described retainer component with this nut of turn.

Aforesaid plug-in tool construction, wherein the bottom, socket part is thinner neck, this neck is provided with a pivot hole and storage tank is pivoted, and provides the space that the elevation angle curves, described socket part by this neck.

Aforesaid plug-in tool construction, its pivot hole is an ovalize, and a spring is set to support solid described socket part in described storage tank.

This socket part is to be provided with an inserting port can replace for pulling part plug, and the user can control the flexible of retainer component by adjusting structure, whether fastens the location with the socket part to adjust retainer component; When needs are adjusted the angle of inclination, socket part, can by adjust structure make retainer component and socket part from, again retainer component and socket part engagement are located after the extremely required angle to be adjusted, so reach the effect of fixedly sleeved institute's hue angle, and replaceable pulling part and improve practicality, have novelty, creativeness and practicality.

The beneficial effects of the utility model are, it can improve fixedly adjustment angle of existing hand-held tool head, or pulling part shortcoming such as can't replace, and reach the effect of fixedly sleeved institute's hue angle, and replaceable pulling part and improve practicality.
