Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, present embodiments providing a kind of special spanner, which includes handle 1, back-up wrench head 2 and lives
Wrench head 3, the handle are vertical bar shaped, and the Flexible spanner 3 has fixed chuck and active chuck at hand, and fixed chuck is remote
One end of one end and the handle 1 from clamping opening is detachably connected, and the back-up wrench head is two, and two described solid
It is different to determine driving end specification, the two described one end of back-up wrench head far from clamping opening are slidably mounted on the handle other end respectively
Two sides, and the clamping opening of the two, backwards to being arranged, two back-up wrench heads 2 can be sliding along the length direction of the handle 1 respectively
It is dynamic.By the way that two back-up wrench heads to be slidably arranged in one end of the handle, so that back-up wrench head there are two spanner tools,
So that its is adaptable, and selecting one in use, remaining back-up wrench head can be slid into far from another back-up wrench head, from
And make the space of one end of back-up wrench head to be used more compact, convenient for operation, and Flexible spanner is removably arranged at hand
In the other end of the handle, so that the adaptability of entire spanner further increases.
As shown in figure 3, wherein, it is preferred that the handle is vertical bar shaped plate, and one end end far from Flexible spanner at hand is set
Have abut block 11, two back-up wrench heads respectively two sides corresponding with the handle width direction side walls connection,
Preferably, handle two sides side wall is provided along its length sliding slot respectively, and the back-up wrench head is slidably connected with handle
Place is equipped with draw runner, and the draw runner is extend into the sliding slot, and it is extremely sliding with the draw runner that in-flanges is distinguished in sliding slot notch two sides
Dynamic contact, the draw runner is located at the two sides in sliding slot, and flanging is extremely slidably connected with sliding slot cell wall respectively, the varus of the sliding slot
Side is mutually abutted with the flanging of the draw runner, and the both ends of the sliding slot are extended respectively to close to the both ends of the handle, and institute
Sliding slot is stated close to one end end seals for abutting block, another end opening, two back-up wrench heads respectively can be through cunning
Slot skids off sliding slot and is detached from handle and (when needing to dismantle any one back-up wrench head, need to tear open in advance far from the one end for abutting block
Fall Flexible spanner at hand), to realize that two back-up wrench heads are slided and are detachably connected with handle.
Such as Fig. 4 and Fig. 5, and the handle can be detachably connected with the Flexible spanner by connector 31 at hand, the work
Wrench head is equipped with connector 31 away from the side of clamping opening, and connector 31 is rectangular tube, and one end and Flexible spanner deviate from folder at hand
The side connection of mouth, the other end is open, and handle corresponding end end is convexly equipped with the convex block matched with the connector 31,
The convex block, which can be extend into the connector, is detachably connected the handle with the connector 31.
The bore of two back-up wrenches is respectively 22mm and 27mm in above-mentioned technical proposal, is more suitable for pressure
Table.
As shown in Fig. 2, being additionally provided with and the pressure on handle described in above-mentioned technical proposal close to the one end of Flexible spanner at hand
The box spanner that silk plug matches on power table, the box spanner is vertical with the handle to be connect, and at hand with the Flexible spanner
The plane at place is vertical.Its structure is simple, and easy to use, so that the adaptability of entire spanner further enhances.
Preferably, the box spanner can be detachably connected with the handle, and the box spanner is deviated from its work department
One end be set as regular polygon column, and the seamed edge of the regular polygon column is overlapped with the outer wall of the box spanner, the hand
Corresponding position is equipped with regular polygon hole engaged therewith on handle, and the box spanner extend into the hand far from one end of its work department
On handle in corresponding hole, to realize its being detachably connected with handle.
So that when dismantling pressure gauge corresponding back-up wrench head or Flexible spanner can be matched as needed at hand, or tearing open
Box spanner can be used when unloading or install the silk plug of pressure gauge, so that whole device structure is simple, assembly is convenient, using flexible.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
