Abstract
The utility model discloses a kind of spanner, the head for clamping fastener (1) that this spanner comprises handle (2) and arranges in described handle (2) one end, described head (1) is provided with for holding described securing member notch part at least partially (12), the opening part of this notch part (12) be provided with two relative to being fastened on the latch (11) in the groove of described securing member outer surface respectively.When the spanner provided with the utility model carries out dismounting to securing member, firm grip, not easily slippage, make dismounting more for convenience, and dismounting efficiency is higher.
Description
Technical field
The utility model relates to technical field of tools, particularly, relates to a kind of spanner.
Background technology
In prior art, one or more fasteners is dismantled as round nut etc. is not suitable for the instruments such as existing spanner, round nut profile is generally circle, as shown in Figure 1, the outer circumference surface of round nut is provided with multiple groove A, can with stop washer with the use of, assemble time, the interior tongue of stop washer can insert in the groove A of round nut, realizes the locking of round nut.
But, because round nut profile is circular, when dismounting being carried out to round nut with instruments such as conventional spanners, clamp not strongly, easy slippage, thus efficiency is lower when carrying out dismounting to round nut.
Utility model content
The purpose of this utility model is to provide a kind of spanner, comparatively firm with this spanner clamping fastener, not easily slippage, and when making dismounting securing member, efficiency is higher.
To achieve these goals, the utility model provides a kind of spanner, the head for clamping fastener that this spanner comprises handle and arranges in described handle one end, described head is provided with for holding described securing member notch part at least partially, the opening part of this notch part be provided with two relative to being fastened on the latch in the groove of described securing member outer surface respectively.
Preferably, described notch part is the pentagonal configuration with described opening.
Preferably, the thickness of described head is less than 3mm.
Preferably, the thickness of described head is 1.5-2mm.
Preferably, the angle between the bearing of trend of the line of two described latches and the longitudinal direction of described handle is less than 90 degree.
Preferably, described angle is 45 degree to 70 degree.
Preferably, described handle and described head one-body molded.
The spanner that the utility model provides, by arranging the notch part that holds at least part of securing member at the clamping head of firm and arranging two for being fastened on the latch in the groove of securing member outer surface at the opening part of notch part, make with this spanner clamping fastener comparatively firm, not easily slippage, thus to the dismounting of securing member more for convenience, dismounting efficiency is higher.
Other features and advantages of the utility model are described in detail in detailed description of the invention part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, but does not form restriction of the present utility model with detailed description of the invention one below.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of round nut in prior art;
Fig. 2 is the structural representation of the spanner in a kind of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of spanner, as shown in Figure 2, the head 1 for clamping fastener that this spanner comprises handle 2 and arranges in handle 2 one end, wherein, head 1 is provided with for holding described securing member notch part 12 at least partially, the opening part of this notch part 12 be provided with two relative to being fastened on the latch 11 in the groove of securing member outer surface respectively.
The spanner that the utility model provides, be particularly useful for round nut, outer circumference surface due to round nut is provided with multiple groove, when carrying out dismounting to round nut, two latches 11 on the head 1 of spanner are fastened in two grooves on round nut outer circumference surface, then pull handle 2 pairs of round nuts and apply moment, dismounting can be carried out to round nut.Certainly, this spanner is not limited to dismounting round nut, and some other arranges reeded securing member and this spanner also can be adopted to carry out dismounting.The spanner structure that the utility model provides is simple, comparatively firm to the clamping of securing member, not easily slippage, thus dismounting securing member more for convenience, and dismounting efficiency is higher.
Preferably, handle 2 and the head 1 of this spanner can be one-body molded, and preferably, this spanner can adopt galvanized steel plain sheet cutting to make, and selection is convenient.
In present embodiment, as shown in Figure 2, notch part 12 on this Wrench head 1 can be the pentagonal configuration with opening, when head 1 clamping fastener, securing member be placed in this notch part 12 at least partially, the structure of notch part 12 is not limited to the pentagonal configuration shown in Fig. 2, also can be circular etc., as long as this spanner is when clamping fastener, can accommodating part fasteners.
For enabling spanner carry out dismounting to the securing member being fixed on narrow space, the thickness of spanner (mainly the thickness of the head 1 of spanner) can be set to be less than 3mm, preferably, this thickness can be 1.5-2mm.
The large I of the spanner that the utility model provides adjusts according to the size of the securing member of institute's dismounting, distance a between two latches 11 and the size of notch part 12 need adapt to the size of securing member, the width b of two latches 11 simultaneously on head 1 need be less than the width of the groove on securing member, in the groove that latch 11 can be sticked on securing member.
In addition, for easy to use, as shown in Figure 2, the angle β between the bearing of trend of the line of two latches 11 and the longitudinal direction of described handle 2 is less than 90 degree.Preferably, this angle is 45 degree to 70 degree.
The handle 2 of this spanner also can arrange through hole 21, and this spanner hangs by this through hole 21 when idle.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
