Description
Technical field
The present invention relates to machine tool technical field more particularly to a kind of novel mechanical spanners.
Background technology
Spanner is a kind of commonly installation and extracting tool, and bolt, screw, nut and other spiral shells are twisted using lever principle
Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware, and spanner is usually formed with clamp holder in the one or both ends of shank
Portion applies external force shank and applies external force, can twist bolt or nut holds the opening or sets of holes of bolt or nut, along spiral shell when use
Line direction of rotation applies external force in shank, can twist bolt or nut.
Currently, existing mechanical wrench structure is more single, often it is merely able to the two sides of nut being clamped, in nut
In dismounting or fastener cycle, idle running easily occurs with nut or is directly detached from nut for spanner, and operating process is very inconvenient, work
It is less efficient.
Invention content
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of novel mechanical spanner proposed.
To achieve the goals above, present invention employs following technical solutions：A kind of novel mechanical spanner, including toroidal shell
Body and operating lever, and the bottom of circular shell is welded with operating lever, the center position of the circular shell offers circular port,
And the inside of circular port is angularly distributed there are six grip block, the side far from the circular port center of circle is welded on six grip blocks
It is connected to screw-casing, and the inside of six screw-casings is socketed with helical axis, justifies far from circular port on six helical axis
The side of the heart is welded with bevel gear, and the side center position of six bevel gears passes through the second shaft and toroidal shell
The inner surface wall of body is flexibly connected, and opens up fluted in the vertical center line of the operating lever, and the internal activity of groove is connected with roller
Axis.
As further describing for above-mentioned technical proposal：
Packet is equipped with the raised rubber for increasing rubbing action on the appearance wall of the roll shaft.
As further describing for above-mentioned technical proposal：
Six bevel gears engage connection between any two.
As further describing for above-mentioned technical proposal：
In six second shafts, has and only there are one the first rotating shafts by being arranged inside operating lever to be welded with roll shaft
It connects.
As further describing for above-mentioned technical proposal：
The both sides of the screw-casing and it is welded with spacing block set positioned at the internal symmetry of circular shell.
In the present invention, first, first rotating shaft and the second shaft is driven to rotate simultaneously by the rotation of roll shaft, so that six
A bevel gear rotates simultaneously, and the rotation of bevel gear drives helical axis rotation, so that screw-casing and grip block are along circular port
The center of circle direction movement, finally, six grip blocks can be fitted closely with the appearance wall of nut, at this point, again firmly rotation operation
Bar can easily complete fastening or the dismantlement work of nut, this is compact-sized rationally, and rapid operation is convenient, can make nut
Appearance wall uniform force, spanner will not occur idle running or is detached from nut during whole operation, effectively raise work effect
Rate.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, a kind of novel mechanical spanner, including circular shell 1 and operating lever 2, and the bottom of circular shell 1 with
Operating lever 2 is welded, and the center position of circular shell 1 offers circular port 111, and the inside of circular port 111 is angularly distributed
There are six grip block 10, the side far from 111 center of circle of circular port is welded with screw-casing 8, and six spiral shells on six grip blocks 10
The inside of rotation set 8 is socketed with helical axis 7, and the side far from 111 center of circle of circular port is welded with bevel gear on six helical axis 7
5, and the side center position of six bevel gears 5 is flexibly connected by the second shaft 6 with the inner surface wall of circular shell 1, behaviour
Make to open up fluted 31 in the vertical center line of bar 2, and the internal activity of groove 31 is connected with roll shaft 4.
Packet is equipped with the raised rubber for increasing rubbing action on the appearance wall of roll shaft 4, and six bevel gears 5 nibble between any two
It closes and connects, in six the second shafts 6, have and only there are one the first rotating shafts 3 by being arranged inside operating lever 2 to be welded with roll shaft 4
It connects, the both sides of screw-casing 8 and is welded with spacing block set 9 positioned at the internal symmetry of circular shell 1.
The convenient rotation that roll shaft 4 is manually controlled with hand of setting of raised rubber, spacing block set 9 are mainly used for limiting screw thread
The displacement effect in 8 rotation directions is covered, to ensure under the rotary action of helical axis 7, thread bush 8 can be along a certain straight line
Direction moves back and forth so that structure is more reliable and more stable, and six spacing block sets 10 to six faces of nut for being carried out at the same time folder
It holds so that each face uniform force of nut is avoided and skidded between nut and spanner consequently facilitating easily unloading lower nut.
Operation principle：In use, the circular port 111 of the mechanical wrench to be sleeved on to the outer of the nut for needing dismounting or fastening
Then side pushes roll shaft 4 to rotate with thumb, drive first rotating shaft 3 and the second shaft 6 to rotate simultaneously by the rotation of roll shaft 4,
So that six bevel gears 5 rotate simultaneously, the rotation of bevel gear 5 drives helical axis 7 to rotate so that screw-casing 8 and
Grip block 10 is moved along the center of circle direction of circular port 111, and finally, six grip blocks 111 can closely be pasted with the appearance wall of nut
It closes, at this point, firmly rotation operating lever 2 can easily complete fastening or the dismantlement work of nut, and whole operation process again
In, spanner will not dally with nut, time saving and energy saving, effectively raise working efficiency.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
