Abstract
The utility model discloses a socket spanner with the adjustable size. The socket spanner with the adjustable size comprises a handle, a transmission shaft and a socket head, wherein the handle penetrates through the top end of the transmission shaft and is perpendicular to the transmission shaft; the socket head is arranged at the bottom end of the transmission shaft; the outer face of the transmission shaft is connected with an adjusting cone in a sleeved mode through threads; the conical tip of the adjusting cone is downwards arranged; the socket head comprises a limit board fixedly connected to the bottom end of the transmission shaft; the edge of the limit board is inwards concave to form at least two notched disc chucks; the notches of the limit board are provided with arc rods; the arc rods are movably connected with nut clamping blocks in a sleeved mode; the inner side of the upper end of each nut clamping block abuts against the conical face of the adjusting cone; the cross section of each nut clamping block is in an isosceles trapezoid shape. The size of the socket head can be adjusted, and the trouble of frequently replacing the old sleeve head with a new sleeve head when nuts of different types are assembled and disassembled is avoided.
Description
Technical field
The utility model relates to a kind of instrument of dismounting nut, relates in particular to a kind of box spanner that can regulate size.
Background technology
The instrument of dismounting nut generally adopts sheet shape spanner or the large class of box spanner two, has sizing spanner and adjustable monkey wrench of various models in sheet spanner, but sheet spanner cannot some installation sites of dismounting the nut of dark (around being stopped); Box spanner can the darker nut in dismounting installation site, but the size of collet head is changeless, causes people in the time processing the nut of different model, to need constantly to change collet head.
Utility model content
the technical problems to be solved in the utility model is to provide a kind of box spanner that can regulate size, and the size of collet head can regulate, the frequent trouble of changing collet head when having avoided dismounting different model nut.
To achieve these goals, technical solution adopted in the utility model is: a kind of box spanner that can regulate size, comprise handle, power transmission shaft and collet head, described handle runs through the top of power transmission shaft vertical with power transmission shaft, collet head is arranged on power transmission shaft bottom, the outside of described power transmission shaft is connected to cone governor by thread bush, the cone point of cone governor arranges downwards, described collet head comprises the limiting plate that is fixedly connected on power transmission shaft bottom, limiting plate is that edge caves inward and forms the floral disc shape of at least two breach, the indentation, there of limiting plate is provided with bow, on bow, movable sleeve is connected to nut fixture block, inner side, upper end and the conical surface of cone governor of nut fixture block offset, the cross section of nut fixture block is isosceles trapezoid.
As a kind of optimal technical scheme of the present utility model, on each described bow, be socketed two nut fixture blocks.
As a kind of optimal technical scheme of the present utility model, described cone governor is top in shape, and the axis of passing through cone governor offers the screw mating with power transmission shaft.
As a kind of optimal technical scheme of the present utility model, described cone governor is conical, and the axis of passing through cone governor offers the screw mating with power transmission shaft.
As a kind of optimal technical scheme of the present utility model, described bow and described limiting plate concentric.
As a kind of optimal technical scheme of the present utility model, the axis angle of described adjusting element of a cone and cone governor is 10 ° ~ 45 °.
The beneficial effect that adopts technique scheme to produce is: the utility model is by rotating cone governor, cone governor is moved up and down along power transmission shaft, the conical surface of cone governor forces nut fixture block taking the bow angle suitable as axle turns to, the bottom of nut fixture block is flared to suitable size thereupon, to adapt to the nut of different model, avoid the trouble of continuous replacing collet head.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is stereogram of the present utility model.
Fig. 2 is that in Fig. 1, A part is removed the local amplification stereogram after a nut fixture block.
In figure: 1, handle 2, power transmission shaft 3, cone governor 4, collet head 41, limiting plate 42, bow 43, nut fixture block.
Detailed description of the invention
Referring to attached Fig. 1 and 2, the structure of a detailed description of the invention of the utility model comprises handle 1, power transmission shaft 2 and collet head 4, described handle 1 runs through the top of power transmission shaft 2 vertical with power transmission shaft 2, collet head 4 is arranged on power transmission shaft 2 bottoms, the outside of described power transmission shaft 2 is connected to cone governor 3 by thread bush, the cone point of cone governor 3 arranges downwards, described collet head 4 comprises the limiting plate 41 that is fixedly connected on power transmission shaft 2 bottoms, limiting plate 41 forms the floral disc shape of at least two breach for edge caves inward, the indentation, there of limiting plate 41 is provided with bow 42, on bow 42, movable sleeve is connected to nut fixture block 43, inner side, upper end and the conical surface of cone governor 3 of nut fixture block 43 offset, the cross section of nut fixture block 43 is isosceles trapezoid.
On each described bow 42, be socketed two nut fixture blocks 43.
Described cone governor 3 is top in shape, and cone governor 3 also can adopt taper shape, and the axis of passing through cone governor 3 offers the screw mating with power transmission shaft 2.
Described bow 42 and described limiting plate 41 concentrics.
The axis angle of the bus of described cone governor 3 and cone governor 3 is 10 ° ~ 45 °.
Operation principle of the present utility model is: when use, cone governor 3 is raise along power transmission shaft 2, the bottom of nut fixture block 43 is outwards opened, the bottom of nut fixture block 43 is enclosed in needs the nut of dismounting outside, then cone governor 3 is declined along power transmission shaft 2, the conical surface of cone governor 3 forces the top of nut fixture block 43 outwards to be opened, simultaneously, because nut fixture block 43 forms lever taking bow 42 as fulcrum, inwardly tighten up the bottom of nut fixture block 43, the object that reaches clamping nut, finally can complete the work of dismounting nut by pulling handle 1.
Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the Single restriction condition to its technical scheme itself.
