Description
Technical field
The utility model is related to monkey wrench technical field, especially a kind of differential spanner.
Background technology
Spanner is a kind of conventional installation and extracting tool.Bolt, screw, nut and other spiral shells are twisted using lever principle
Line tightly holds the opening or the hand tools of trepanning firmware of bolt or nut.
Existing monkey wrench be all driven by adjusting worm screw activity clamping part clamp nut, when need adjustment
, it is necessary to which a hand holds the handle of monkey wrench during clamp distance, a hand adjusting bolt adjusts inconvenience, and take
When it is laborious, use inefficiency.
Utility model content
The technical problems to be solved in the utility model is：It is not square during existing monkey wrench adjustment clamp distance in order to solve
Just, and the problem of waste time and energy, the utility model provides a kind of differential spanner, passes through major thread area and the first screwed hole screw thread
Connection, minor thread area be connected with the second screwed hole so that when rotation grip part, left clamping part and right clamping part at the same draw close or
Separation carrys out gripping objects, only needs a hand just to rotate grip part and reaches the purpose of adjustment clamp distance, easy to adjust.
The utility model solves the technical scheme that its technical problem used：A kind of differential spanner, including supporting rod, folder
Portion and connecting rod are held,
One end of the supporting rod is grip part, and the other end is provided with threaded portion, and the threaded portion includes major thread area and small
Threaded area, the pitch in the major thread area is more than the pitch in minor thread area；
The clamping part includes left clamping part and right clamping part, the left clamping part provided with the first synchronous hole and with small spiral shell
The second synchronous hole and the screw thread with major thread area are correspondingly provided with the first screwed hole that the screw thread in line area coordinates, the right clamping part
The second screwed hole coordinated；
The major thread area is threadedly coupled with the first screwed hole, and the minor thread area is connected with the second screwed hole so that when
When rotating grip part, left clamping part and right clamping part are drawn close or separated simultaneously, and the connecting rod is same through the first synchronous hole and second
The synchronous holes of step Kong Bingyu first and the second synchronous hole are slidably connected.
In order to increase the frictional force of gripping objects, the clamping face of the left clamping part and right clamping part is provided with anti-slop serrations.
Specifically, the left clamping part and right clamping part are isosceles trapezoidal structure.
In order to ensure the balance of stress, the supporting rod both sides are symmetrical arranged connecting rod.
Preferably, the screw thread in the major thread area is dextrorotation, the screw thread in the minor thread area is left-handed.
Grip for convenience, grip sleeve is arranged with outside the grip part.
The beneficial effects of the utility model are：The utility model provides a kind of differential spanner, simple in construction, passes through rotation
Grip part so that left clamping part and right clamping part, which are drawn close or separated simultaneously, carrys out gripping objects, and user only needs a holding to handle
Grip part can just carry out the adjustment of clamp distance, greatly facilitate the adjustment of clamp distance, also reduce the work of user
Intensity, improves operating efficiency.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of differential spanner of the present utility model.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in figure 1, a kind of differential spanner, including supporting rod 1, clamping part 2 and connecting rod 3, one end of supporting rod 1 is gripping
Portion, the other end is provided with threaded portion 12, and threaded portion 12 includes major thread area 121 and minor thread area 122, major thread area 121 and small spiral shell
Line area 122 is connected as one, and the pitch of the pitch more than minor thread area in major thread area；Clamping part 2 includes the left He of clamping part 21
Right clamping part 22, the first screwed hole that left clamping part 21 coordinates provided with the first synchronous hole and with the screw thread in minor thread area 122 is right
The second synchronous hole and the second screwed hole with the screw thread cooperation in major thread area 121 are correspondingly provided with clamping part 22；Major thread area 121
It is threadedly coupled with the first screwed hole, minor thread area 122 is connected with the second screwed hole so that when rotating grip part, left clamping part
21 and right clamping part 22 draw close or separate simultaneously, connecting rod 3 through the first synchronous hole and second the first synchronous holes of synchronization Kong Bingyu with
Second synchronous hole is slidably connected.
In a kind of specific embodiment, the clamping face of left clamping part 21 and right clamping part 22 is provided with anti-slop serrations 23.
Wherein left clamping part 21 and right clamping part 22 are isosceles trapezoidal structure.
Preferably, being symmetrical arranged connecting rod 3 on supporting rod 1.
Preferably, the screw thread in major thread area 121 is dextrorotation, the screw thread in minor thread area 122 is left-handed.
Wherein when left clamping part 21 and right clamping part 22 are drawn close, left clamping part 21 and right clamping part 22 can be reached simultaneously
