Description

Improved ratchet spanner driving head

Technical field

The utility model relates to a kind of hand-operated tools, relates in particular to a kind of turn driving head fast, makes can the go ahead of the rest improved ratchet spanner driving head of turn workpiece of driving head.

Background technology

In hand-held tool industry circle, existing ratchet spanner driving head has two kinds of structures mostly, and is a kind of for there not being the driving head of rotating disk, as shown in Figure 5, this driving head 5 has a cylinder 51, and these cylinder 51 1 sides latch piece 52 that is pivoted is for engaging with the hook tooth 61 of a ratchet spanner 6, these driving head 5 one ends have a joint 53, for joining with tool heads, this driving head 5 end in addition then is provided with a knob 54, engages with the hook tooth 61 of this ratchet spanner 6 for this latch piece 52 of control.

This kind driving head 5 in use, is that the joint 53 with this driving head 5 puts a tool heads, and this tool heads is embedded on the workpiece, again this ratchet spanner 6 is come back rotation, to screw this workpiece.Yet, during workpiece turn in the early stage,, be difficult for turn in the time of therefore can making ratchet spanner 6 turn in the early stage because of workpiece is to be under the loosening state, thus the user can be earlier with hand with the workpiece turn to certain tightness, with ratchet spanner 6 it is screwed again.

Another kind of for having the driving head of rotating disk, as shown in Figure 6, the one of holding in addition of these driving head 5 tool joints 53 is connected with a rotating disk 55.Be connected with driving head 5 one by this rotating disk 55, and allow the user directly rotate this rotating disk 55, go ahead of the rest the turn workpiece to certain tightness for the user with hand.

Because the driving head 5 of this tool rotating disk 55, its rotating disk 55 is that one is connected with in driving head 5 one ends, just, this driving head 5 is in the turning mode, and segmentation goes out rotating disk 55 with these driving head 5 turning, and turning goes out cylinder 51 then, reface goes out joint 53, and this driving head 5 is materials made from cold forging, and material really up to the mark is added the processing of multiple tracks, so very time-consumingly on the processing procedure takes a lot of work, easily makes cost to improve.And this driving head 5 must be selected for use and the base material of rotating disk 55 with external diameter when getting the raw materials ready base material, more unnecessary part turning is removed, because the external diameter of this rotating disk 55 much larger than the cylinder external diameter of driving head 5, therefore can be wasted a lot of materials, cost is increased.

In addition; ratchet spanner 6 is for making appearance looks elegant; regular meeting establishes the lever cover of a tool color or decorative pattern in grip; when this rotating disk 55 is painted if will cooperate the color of this lever cover; then must rotating disk 55 parts be painted separately with the mode of baking vanish, thus, not only increase processing procedure loaded down with trivial details, also can increase cost of processing; and the baking vanish of this rotating disk 55 can come off in use for some time, and causes apparent not attractive in appearance.

In addition, because being one, this rotating disk 55 is connected with on driving head 5, think the needs that adapt to the client, and must prepare the tool rotating disk simultaneously or not have two kinds of driving heads of rotating disk, so, quantity in stock is increased, and this tool rotating disk or do not have two kinds of driving heads of rotating disk can't be shared, cause the difficulty in the scheduling.

Summary of the invention

In order to overcome the above-mentioned shortcoming that existing ratchet spanner driving head exists, the utility model provides a kind of improved ratchet spanner driving head, it can be simplified procedure, reduce cost, and random turn colors is to cooperate the color of ratchet spanner lever cover, and increase ratchet spanner integral body is attractive in appearance, improve the texture of ratchet spanner, and visual client need add rotating part or not add rotating part, not only very flexible in the product scheduling, also can allow quantity in stock reduce, and whole cost is reduced.

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

A kind of improved ratchet spanner driving head, be provided with a metal body, it is characterized in that, described body one end is in conjunction with the rotating part of a plastic shaping one, the end that this body combines with this rotating part is provided with several embedding holes, and this body end in addition then has a joint, and the end that this rotating part combines with this body has several embedding bars, each embedding bar is embedded in respectively in the embedding hole of body, and this rotating part is combined with body.

Aforesaid improved ratchet spanner driving head, wherein the embedding bar of rotating part is a round bar body.

The beneficial effects of the utility model are, it can be simplified procedure, reduce cost, random turn colors, with the color that cooperates the ratchet spanner lever to overlap, and increase the attractive in appearance of ratchet spanner integral body, improve the texture of ratchet spanner, and visual client need add rotating part or not add rotating part, not only in the product scheduling, can apply in a flexible way, also can allow quantity in stock reduce, reduce cost.

The specific embodiment

See also Fig. 1 and Fig. 2, it mainly is in conjunction with a rotating part 2 at a driving head 1 one ends for the utility model, this driving head 1 is the ratchet D head of an existing ratchet spanner 3, the end that this driving head 1 combines with this rotating part 2 is provided with two embedding holes 11 and a pivoted hole 15, its driving head 1 end in addition then has a joint 12, for joining with tool heads, a latch piece 14 is pivoted on the cylinder 13 of this driving head 1.This latch piece 14 is hubbed at this pivoted hole 15 by an axostylus axostyle 16, and this driving head 1 is provided with a knob 17 in conjunction with an end of this rotating part 2, engages with the hook tooth 31 of this ratchet spanner 3 for this latch piece 14 of control.

This rotating part 2 has two embedding bars 21 with relative each 11 place, embedding hole of an end that driving head 1 combines, in the present embodiment, this rotating part 2 is the disc of a plastics ejection formation, but so these embedding bar 21 one ejection formations, this embedding bar 21 is a cylinder, each embedding bar 21 of this rotating part 2 can be embedded in the embedding hole 11 interior (as shown in Figure 3) of driving head 1 respectively, is incorporated on the driving head 1 for rotating part 2.In fact, can make it in conjunction with more firm in the be harmonious face gluing of rotating part 2 with driving head 1.

During use, the user puts a tool heads with the joint 12 of this driving head 1 earlier, and this tool heads is embedded on the workpiece, directly rotate this rotating part 2 with hand again,, make the quick turn of workpiece to certain tightness with this workpiece of turn of going ahead of the rest, use ratchet spanner 3 rotating drive 1 again, to screw this workpiece.

Because this rotating part 2 adds and is located on the existing driving head 1, with the design of driving head 1 for separating, therefore, the size of visual existing driving head 1 and cooperate making, combine with this driving head 1 again, and need not make the driving head 1 of tool one rotating part 2 in addition, and the embedding hole 11 of this driving head 1 and pivoted hole 15 can process simultaneously, can reduce the program and the manufacturing cost of processing.

Moreover this existing driving head 1 can be processed this embedding hole 11 in advance and get the raw materials ready, and looks the client and need add rotating part 2 again or not add rotating part 2, not only can apply in a flexible way in product scheduling and can allow quantity in stock reduce, and whole cost is reduced.

In addition, as shown in Figure 4, because this rotating part 2 is plastics ejection formations, therefore this rotating part 2 can one-body molded this embedding bar 21, and need not process in addition again, and but this its color of rotating part 2 random variation or decorative pattern to be cooperating the color or the decorative pattern of this ratchet spanner 3 levers cover 32, and increase the attractive in appearance of ratchet spanner 3 integral body, to improve the texture of ratchet spanner 3.
