Abstract
The utility model discloses a thin multifunctional ratchet wrench. The thin multifunctional ratchet wrench comprises a main body and a handle, wherein the main body is mainly and internally provided with an outer-tooth ratchet, a moon-shaped bidirectional pawl, a limiting pin and a spring of the moon-shaped bidirectional pawl, and a movable wrench head coaxially mounted on the outer-tooth ratchet; and the improved points are that the movable wrench head is composed of a wrench head body and a fastening nut. According to the thin multifunctional ratchet wrench, disclosed by the utility model, the fixing way of the wrench head is changed, specifically a positioning cover is changed into the fastening nut, so that the tail part of the wrench head can stretch out of the upper end face of the main body; and the whole wrench head can move upwards to enable the head part to be embedded into the main body, so that the wrench head is thinned to adapt to operation in a narrow space. Due to the change of the fixing way of the wrench head, the tail end of the wrench head is no longer sealed; and if the nut wrench head is made into a hollow structure, operation can be performed on a nut on a long bolt. Therefore, the function of the wrench is added.
Description
Technical field
The utility model relates to a kind of multifunctional ratchet wrench, particularly a kind of slim multifunctional ratchet wrench.
Background technology
In prior art, the structure of common multifunctional ratchet spanner is shown in Chinese patent 90204935.6, it comprises a main body and a handle, comprise an external tooth ratchet, a two-way ratchet and a driving end that is installed on the external tooth ratchet in main body, described driving end is fixed on the external tooth ratchet by a locating cover.Because driving end is fixing by locating cover, its tail end is positioned at the below of locating cover, and therefore, in the constant situation of driving end length, the head of driving end all stretches out main body, and the thickness of spanner is increased, and is difficult to adapt to the fastening operation of small space; Moreover if driving end is the nut spanner head, its tail end cap seal that is positioned closes, so that it can't be to the nut implementation and operation on the stay bolt.
The utility model content
The purpose of this utility model is for the problem that exists in the prior art, and a kind of slim multifunctional ratchet wrench is provided, and makes it adapt to the operation of small space.
For achieving the above object, the technical solution of the utility model is as follows:
It comprises a main body and a handle, described handle and main body connect firmly together, an external tooth ratchet mainly is housed in described main body, month two-way ratchet of type, the spacer pin of the two-way ratchet of month type and spring and coaxial be contained on the described external tooth ratchet a portable plate at hand, it is characterized in that: described Flexible spanner is made of a driving end body and a clamp nut at hand, described driving end body is by the driving end section of front portion, the six square shaft sections at middle part and the spiro rod section of afterbody consist of, be provided with six side's central shaft holes at described external tooth ratchet, described driving end body embeds in the main body, and wherein section is arranged in six square shaft holes of described external tooth ratchet, and its afterbody is fixed by described clamp nut.
Further improved technical scheme is as follows:
Described driving end body is a nut spanner head, and the middle part of this nut spanner head and afterbody are provided with the central shaft through hole.
Described spacer pin and spring are along the axial installation of spanner, namely be provided with an axial installing hole in described main body with the contact-making surface that is connected of handle, described spacer pin and spring are coaxial to be installed in this axial installing hole, one end of described spring acts on handle, its other end acts on the afterbody of spacer pin, and the head projecting shaft of described spacer pin is conflicted on two-way ratchet to installing hole.
Can find out by above-mentioned improvement, the utility model changes the fixed form of driving end, it changes into clamp nut with locating cover, make the upper surface of the extended main body of afterbody of driving end, then driving end can move on the whole, its head is embedded in the main body, thereby make the thickness attenuation of Wrench head, adapt to the operation of small space.Because the change of driving end fixed form is no longer sealed the driving end tail end, if the nut spanner head is made hollow-core construction, just can to the nut implementation and operation on the stay bolt, increase the function of spanner again.

The specific embodiment
Referring to Fig. 1～5, this spanner comprises a main body (1) and a handle (11), described handle and main body screw connect firmly together, be provided with a pad (10) between the contact-making surface in described handle and being connected of main body, an external tooth ratchet (2) and month two-way ratchet of type (6) are housed in described main body (1), described external tooth ratchet is fixed in the ratchet chamber (1-1) of main body by a back-up ring (5), the two-way ratchet of type was fixed in the ratchet cavities (1-2) of main body by a control handle (7) in described month, described control handle (7) links by square structure (6-1) and month two-way ratchet of type (6), and moon spacer pin of the two-way ratchet of type (8) and spring (9) also are housed in described main body; Described control handle (7) can drive the two-way ratchet of moon type and rotate, and by the evolution of the two-way ratchet of moon type, realizes suitable, contrary conversion of removing; Coaxially a portable plate is housed at hand in that described external tooth ratchet (2) is upper, described Flexible spanner is made of a driving end body (3) and a clamp nut (4) at hand, described driving end body (3) is by the driving end section (3-1) of front portion, the six square shaft sections (3-2) at middle part and the spiro rod section (3-3) of afterbody consist of, be provided with six side's central shaft holes (2-1) at described external tooth ratchet (2), described driving end body (3) embeds in the main body (1), and wherein section is arranged in six square shaft holes of external tooth ratchet, and its afterbody is fixing by described clamp nut (4).Described driving end body can have multiple different type in order to changing, as: nut spanner head, double offset ring spanner are at hand, cubic driving end, hexagon be first-class, during replacing, clamp nut unloaded, and can unload easily driving end and change.If the driving end body is the nut spanner head, the middle part of this nut spanner head and afterbody are provided with central shaft through hole (3-4), can realize the fastening operation to the nut on the stay bolt.
The course of work of this spanner is: referring to Fig. 1,2,5～7, stir first control handle (7), be located at along removing or the contrary gear (shown in Fig. 5,7) of removing, under the effect of spring (9), the conflict month two-way ratchet of type (6) of spacer pin (8) then, make the two-way ratchet of moon type (6) and external tooth ratchet (2) engagement, at this moment, clockwise or counter-clockwise swing handle (11), then month two-way ratchet of type (6) is stirred the clockwise or counterclockwise one-directional rotation of external tooth ratchet (2), realizes fastening operation.When control handle (7) when being arranged in gear (as shown in Figure 6), month two-way ratchet of type (6) breaks away from external tooth ratchet (2), and the external tooth ratchet can dally clockwise or counterclockwise.
Spacer pin in the above-mentioned existing patent and spring are perpendicular to the wrench shaft installation, and this structure makes spacer pin be not easy to install, and drops easily.For this reason, this routine described spacer pin (8) and spring (9) are along the axial installation of spanner, referring to Fig. 1,3, namely be provided with an axial installing hole (1-3) in described main body (1) with the contact-making surface that is connected of handle (11), described spacer pin (8) and spring (9) are coaxial to be installed in this axial installing hole, one end of described spring (9) acts on handle (11), its other end acts on the tail end of spacer pin, and the head projecting shaft of described spacer pin (8) is conflicted on two-way ratchet (6) to installing hole.
