Description
The utility model relates to a kind of fast adjustable spanners.
Spanner is a kind of power tool commonly used, it is of a great variety, movable adjustable spanner wherein is more welcome, this activity adjustable spanner comprises the outer ring of a band handle, ring in one ratchet, interior ring center has a square hole, some have a dop that matches with head bolt or nut different size, select needed dop to put into the ring centre bore during use, ring is rotated in can driving when outer ring forward rotation, and during outer ring backward rotation, interior ring is not rotated, and does not need so again and again spanner to be pulled up so that change to suitable angle from bolt or nut when stubborn same bolt or nut.But this movable adjustable spanner has following shortcoming: 1, this spanner need be equipped with more dop, in use will be in addition with the dop that becomes box, and cumbersome; 2,, when twisting nut on screw rod, tend to be subjected to the restriction of dop solid-end because of screw rod is long so that can't use because an end of the interior ring centre bore of the insertion of dop is solid.
The purpose of this utility model provides a kind of simple in structure, easy to use and be suitable for the fast adjustable spanners of the different bolt of various length.
For achieving the above object, the utility model is taked following design: a kind of fast adjustable spanners, it comprises: the outer ring of a band handle, be connected ring in the ratchet on the described outer ring, it is characterized in that: the ring middle part has a hexagon ring in described, a side of ring is that symmetric points are parallel to described hexagon ring same side and are protruding with two rectangular guidewaies and two dovetail slideways with ring center in described in described, this below, side is protruding with two limited blocks perpendicular to described guide rail, described limited block has groove, two Flexible spanner sheets, its side protrudes out one respectively and has the bare terminal end that angle is the v-depression of 120 degree, the back side of two described Flexible spanner sheets has rectangular recess and dovetail groove respectively, described two Flexible spanner sheets are placed on the rectangular guideway and dovetail slideway of described interior ring by rectangular recess and dovetail groove, described Flexible spanner sheet can slide along described guide rail, described two Flexible spanner sheet two ends are arranged with two screws that are parallel to the perforation of described guide rail respectively, one forward and reverse screw rod is arranged in the screw of described two Flexible spanner sheets, one end, described screw rod middle part is the diameter operating portion bigger than two ends, and described operating position is between described two limited blocks and limit described screw axial by it and move.
One end of described Flexible spanner sheet bare terminal end one side has a groove respectively, and the other end of its opposite side also has a groove respectively, and the two end portions of its bare terminal end was staggered when described two Flexible spanner sheets inwardly were transferred to minimum dimension.
The convex respectively boss that stretches out of described two Flexible spanner sheet bare terminal ends.
Has scale on the described spanner.
Described scale be described in the groove line of the expression size that has of ring top.
The utility model has the advantages that: 1, the utility model is owing to have a hexagon ring in the middle part of the ring in it, one side of interior ring is that symmetric points are parallel to the hexagon ring same side and are protruding with two rectangular guidewaies and two dovetail slideways with interior ring center, this below, side of ring is protruding with two limited blocks perpendicular to guide rail within it, limited block has groove, two Flexible spanner sheets, its side protrudes out one and has the bare terminal end that angle is the v-depression of 120 degree, the back side of Flexible spanner sheet has rectangular recess and the dovetail groove that supplies rectangular guideway and dovetail slideway to insert, the Flexible spanner sheet can slide along guide rail, Flexible spanner sheet two ends are arranged with two screws that connect that are parallel to guide rail, its middle part of one forward and reverse screw rod is the diameter operating portion bigger than two ends, and move between two limited blocks and by its restriction screw axial the operating position.Rotation by forward and reverse screw rod can make two Flexible spanner sheets move in or out, when the bare terminal end that two Flexible spanner sheets have a v-depression is positioned at the ring hexagon ring outside, then hexagon ring is the maximum functional size, the utility model has compared with prior art saved many dops, simple in structure, easy to use and the nut or the bolt that are suitable for varying in size.2, the utility model has the bare terminal end that angle is the v-depression of 120 degree because its two Flexible spanners sheet side protrudes out one respectively; two Flexible spanner sheets are combined as and pull ring during use; two Flexible spanner sheets contact with the head or the nut of bolt with four faces with two angles, help protecting the head of bolt or nut not to be damaged.3, the utility model is because an end of its Flexible spanner sheet bare terminal end one side has a groove, and the other end of its opposite side also has a groove, and the two end portions of its bare terminal end was staggered when two Flexible spanner sheets inwardly were transferred to minimum dimension.Institute is so that the utility model adjustable dimension expanded range.4, the utility model is because its interior ring center has a hexagon through hole, and two Flexible spanner sheets are combined as pulls general diagonal angle formula clamping nut or the bolt head on four sides of adopting in ring back, so be suitable for the different bolt of various length.5, the utility model has increased the free degree of spanner working space owing to the convex respectively boss that stretches out of its two Flexible spanners sheet bare terminal end.6, the utility model can once regulate putting saving of work and time in place owing to be provided with scale when adjusting screw(rod).7, the utility model is because two Flexible spanner sheet two ends are arranged with two screws that are parallel to the perforation of guide rail respectively, thus after a screw has been given a piece of bad advice also available another one screw, can reduce expenses, make the Flexible spanner sheet have interchangeability simultaneously.
