Abstract

The utility model relates to a ratchet spanner structure improvement, particularly a ratchet spanner which can be driven by an electric or pneumatic tool in a narrow space so as to process force application. In the ratchet spanner structure improvement, a substrate is clamped between an upper fixing sheet and a lower fixing sheet, both ends of the upper fixing sheet and the lower fixing sheet are respectively provided with ratchet spanner spacing holes so that ratchet wheels can be spaced in the ratchet spanner spacing holes. And the two ratchet wheels are interlocked by a driving part. An upper hand grip and a lower hand grip, which are oppositely closed to be arranged, are coated on the upper and lower fixing sheets and are fixed by riveted knots of rivets. So when running in the narrow space or on a workpiece limited by space, the ratchet wheel on one side can be driven by the electric or pneumatic tool, while the ratchet wheel on the other side is interlocked by the driving part so that the two ratchet wheels can rotate in the same direction and then the screwed knot element can be disassembled or screwed nd the driving part can be spaced in the hand grip part on the position of the hand grip. When running, the driving part cannot hurt the hands of the user.

Background technology

See also Fig. 4, shown in Figure 5, it is to be employed on the market ratchet spanner at present, it mainly is to tie a pedestal 94 by 92 of last stator 91 and following stators by rivet 93 rivetings, form one on this pedestal 94 and protect edge 941, and two ends form a kerf 942 on this pedestal 94, sheathed spacing for ratchet stop block 943 and flexible member 944, and on being somebody's turn to do, following

stator

91,92 two sides are provided with ratchet spacing hole 911,921, for a

ratchet

95,96 is sheathed spacing in it, as the structure that is, the basic function of one ratchet spanner obviously is provided, yet, along with exquisiteness is more and more stressed in the design of various utensils, such as auto industry, communication industry or accurate industry etc., because of the relation of the assembly between its member and member also becomes increasingly complex, therefore, often there are some elements and element assembly group to be subject to the restriction of structure afterwards, and make gap therebetween limited, but, ratchet spanner 9 needs bigger revolution space in use, begin start smoothly, and be arranged on than small space or be subjected to the workpiece of limited space as aforementioned, because of its revolution space deficiency, and make it use quite inconvenience.

In order effectively to solve aforementioned issues associated, this case creator is engaged in hardware ﹠ tools manufacturing and design accumulation technology and experience for many years based on it, studied improvement from the angle that can locate really and reduce wear, and via repeatedly test and change, eventually generation of the present utility model.

The utility model content

Main purpose of the present utility model is providing a kind of between two ratchets, by the interlock of driving member, and can be by ratchet spanner structural improvement electronic or that pneumatic tool drives.

For reaching above-mentioned purpose, the utility model inserts and puts a pedestal between upper and lower stator, and give riveting knot by rivet, on two ends of this upper and lower stator, be respectively equipped with the ratchet spacing hole, spacing in it for ratchet, and between this two ratchet by a driving member interlock, so, when in small space or when being subjected on the workpiece of limited space start, can be subjected to electronic or air tool driving in an end ratchet, in addition end ratchet then is subjected to the driving member interlock, and can rotate in the same way, and then is reached and disassemble or screw togather this spiral shell knot element.

Another purpose of the present utility model is that a kind of spacing by handle portion is being provided, and makes this driving member limited in it, and when its start, can not injure user's ratchet spanner structural improvement.

The beneficial effects of the utility model are:

The utility model is involutory by the upper and lower handle that is corresponding setting, and fixing by the riveting knot of rivet in the lump, and the user is gripped, and makes driving member in the handle position is limited in handle portion, when its start, can not injure user's hand.

Description of drawings

Relevant the utility model desires to reach above-mentioned purpose, the technology that is adopted, means and effect thereof, enumerate below that a preferred embodiment and conjunction with figs. describe in detail as after, believe purpose, feature and other advantage of this case invention, when can by obtain deeply and concrete understanding, wherein:

Fig. 1 is three-dimensional combination schematic diagram of the present invention.

Fig. 2 is perspective exploded view of the present invention.

Fig. 3 is generalized section of the present utility model.

Fig. 4 is the solid combination schematic diagram for existing ratchet spanner.

The specific embodiment

The utility model structure embodiment sees also Fig. 1～shown in Figure 3, and wherein, the utility model mainly is to contain stator 1 on, once stator 2, a pedestal 3, a ratchet group 4 and a handle portion 5, wherein:

Stator 1 on one, is provided with open-work 11 thereon, and two sides of stator 1 are provided with

ratchet spacing hole

12,13 on this;

Once stator 2, are provided with open-work 21 thereon, and two sides of stator 2 are provided with

ratchet spacing hole

22,23 on this;

One pedestal 3 is to be folded in 1,2 of upper and lower stators, is provided with open-work 31 thereon, and two ends form a kerf 32 on this pedestal 3, sheathed spacing for ratchet stop block 33 and flexible member 34;

One ratchet group 4 be by 11,12,21,22 of the sheathed respectively ratchet spacing holes that is limited in upper and lower stator 1,2 of two

ratchets

41,42, and in 4 sheathed driving members 43 of this ratchet group, this driving member 43 is crawler belt, belt or chain;

One handle portion 5 is to be coated on 1,2 of upper and lower stators by the involutory of upper and

lower handle

51,52, and is provided with open-work 511,521 thereon, and by rivet 53 wear by the open-
