The adjustable spanner disclosed by the invention is applicable to use in bolts or nuts with different dimensional specifications through arranging the adjustable clamping parts in the inner ring body; and the spanner has no need to be taken off and then re-installed for operation every time while operating rotary nuts, thus the operation space is saved.
Description
Technical field
The present invention relates to a kind of spanner, more particularly to a kind of adjustable spanner.
Background technology
Spanner be in mechanically actuated commonly use instrument, existing spanner rotate nut when, if the space residing for nut
Narrow, spanner is difficult to operation, although have the various spanners of size specification, but they often rotate, it is necessary to remove spanner,
Repositioning rotates again, if space is especially little, is difficult to operation.With the development of science and technology, people have invented rotatable
The spanner of one-way operation, but this spanner can only correspond to a kind of nut or bolt of specification, for the spiral shell of different specifications
Female or bolt needs to prepare different spanners, due to this spanner it is relatively costly, it is larger for the burden of user.
The content of the invention
To solve the above problems, the invention discloses a kind of adjustable spanner.
To reach above-mentioned purpose, the method that the present invention is adopted is：A kind of adjustable spanner, including handle, also including outer
Circle body and inner ring body, described outer ring body is connected with handle, perforate is provided with the excircle of described inner ring body, described
Perforate in be provided with spring and pin, downwards depression forms stopper slot for the middle part of the inner periphery of described outer ring body,
The bottom of described stopper slot is provided with skewed slot, and the side of skewed slot is inclined-plane, another side to face directly, described pin one end and bullet
Spring is connected, and is located in perforate, and the other end is stretched in described stopper slot, connects inner ring body and outer ring body；In described inner ring
Two mobilizable clamping parts are provided with vivo, described clamping part can be moved on guide rod, and locked by locking device.
Used as a modification of the present invention, described skewed slot body is provided with least 6.
Used as a modification of the present invention, described guide rod is arranged in inner ring body, and guide rod is provided with two, respectively with clamping
The both sides two in portion connect, and described locking device is arranged on the middle part of clamping part, and is connected with inner ring body by screw rod.
Used as a modification of the present invention, described handle is a telescopic structure, and lock is provided with handle
Tight bolt.
Beneficial effect：
A kind of adjustable spanner that the present invention is provided, by arranging adjustable clamping part in inner ring body, can be applied to
The bolt of different size specification or the use of nut, after in operation rotation nut all need not be removed spanner each time again
Again upper operation is pressed, it is only necessary to continue to rotate again after spanner is rotated in the opposite direction such that it is able to unclamp on nut or bolt
Or locking, operating space is saved, the operation being particularly suited in small space.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the sectional view of the inner ring body and outer ring body connection of the present invention；
Each part is in figure：
1st, pin, 2 skewed slots, 3 inner ring bodies, 4 screw rods, 5 outer ring bodies, 6 guide rods, 7 clamping parts, 8 adjusting nuts, 9 stopper slots, 10 springs,
11 perforates, 12 handles, 13 clamping screws.
Specific embodiment
The technical scheme that the present invention is provided is described in detail below with reference to specific embodiment, it should be understood that following concrete
Embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.
A kind of adjustable spanner as described in Figure 1, including handle 12, it is described also including outer ring body 5 and inner ring body 3
Outer ring body 5 is connected with handle 12, and on the excircle of described inner ring body 3 perforate 11 is provided with, and sets in described perforate 11
It is equipped with spring 10 and pin 1, downwards depression forms stopper slot 9 for the middle part of the inner periphery of described outer ring body 5, described
The bottom of stopper slot 9 is provided with skewed slot, and the side of skewed slot 2 is inclined-plane, another side to face directly, described one end of pin 1 and spring
10 are connected, and are located in perforate 11, and the other end is stretched in described stopper slot 9, connect inner ring body 3 and outer ring body 5.
Two mobilizable clamping parts 7 are provided with described inner ring body 3, described clamping part 7 can be moved on guide rod 6
It is dynamic, and locked by locking device 8.Described guide rod 6 is arranged in inner ring body 3, and guide rod 3 is provided with two, respectively with clamping part 7
Both sides two connect, described locking device 8 is arranged on the middle part of clamping part 7, and is connected with inner ring body 3 by screw rod 4.
Two clamping parts 7 are engaged for grip bolt or nut, and locking device 8 is unclamped when using, and adjust clamping part
7, make two clamping parts 7 clamp bolt or nut, then locked by locking device 8, that is, complete clamping.
Locked using the spanner either unclamped bolt or nut when, first clamping part 7 is adjusted into good position,
Then clamping part is snapped on bolt or nut, is then rotated by handle.Position display is to carry out up time such as in figure
Pin direction rotates, and pin 1 is fallen in skewed slot from inclined-plane, it is impossible to from facing directly out, so as to pass through this skewed slot 2, so outer ring
Body 5 cannot be rotated clockwise relative to inner ring body 3, so as to handle can drive inner ring body 3 to rotate together, so as to realize twisting
Dynamic bolt or nut.
After certain angle is turned, handle can be carried out rotate counterclockwise, in rotate counterclockwise, pin 1 can be from straight
Face is fallen in skewed slot 2, and from inclined-plane out, so as to pass through this skewed slot.Therefore during handle rotate counterclockwise, outer ring body cannot band
The action together of dynamic inner ring body, when the drive inner ring body that continues to turn clockwise after rotate counterclockwise certain angle continue to drive bolt or
Person's nut rotation.In order to ensure that it is arbitrarily angled that rotate counterclockwise can be arrived, described skewed slot body is provided with least 6.
Described handle 12 is a telescopic structure, and clamping screw 13 is provided with handle 13.
A kind of adjustable spanner that the present invention is provided, by arranging adjustable clamping part, Neng Goushi in inner ring body
The use of bolt or nut for different size specification, each time all need not remove spanner in operation rotation nut
Press upper operation again again afterwards, it is only necessary to continue to rotate again after spanner is rotated in the opposite direction such that it is able to by nut or bolt
Unclamp or lock, save operating space, the operation being particularly suited in small space.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, also includes
Constituted technical scheme is combined by above technical characteristic.
