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.
Embodiment: as shown in Figure 1, the clamp tool of the present embodiment includes two spanners 1 and limit adjuster 2;
The bayonet part 11 of two above-mentioned spanners 1 is respectively to block overlap up and down two threaded joint screws;
Above-mentioned limit adjuster 2 is connect with the handle 12 of two above-mentioned spanners 1 respectively, to adjust two above-mentioned spanners 1
Rotate close angle.
In use process, first passes through two spanners and overlap up and down two threaded joint screws are subjected to wide-angle respectively
Pre-tighten adjust, later, accurately adjusted or small spatial dimension in operate when, the bayonet part 11 of two spanners 1 is distinguished
It is stuck in outside two threaded joint screws, later, rotates the handle 12 of two spanners 1 close,
Preload is accurately adjusted to a small range of two threaded joint screws to realize, overcomes operating personnel under narrow space environment
It is difficult to directly to turn the big problem of task difficulty that spanner is pre-tightened.
Preferably, the bayonet part 11 of two above-mentioned spanners 1 is connected by connector 3, enable the compact phase of two spanners 1
Even, conducive to the storage and carrying in later period.
Preferably, above-mentioned connector 3 is steel wire or rope, both ends connect with the bayonet part 11 of two above-mentioned spanners 1 respectively
Fixation is connect, it is compact which enables two spanners 1 to connect, easy to carry and storage.
In general, it is respectively equipped with through-hole or link two relatively close sides of 1 bayonet part 11 of spanner, connector 3
Both ends are detachably connected with two through-holes or link respectively.
Preferably, as illustrated in fig. 1 and 2, above-mentioned limit adjuster 2 includes two movable sleeves 21 and two being arranged in a one-to-one correspondence
Toothed rack 22, two above-mentioned movable sleeves 21 are respectively sleeved on the handle 12 of two above-mentioned spanners 1, and can be respectively along above-mentioned handle
12 slidings, two above-mentioned movable sleeves 21 are respectively equipped with for the perforative through slot of above-mentioned rack gear 22, one end phase of two above-mentioned rack gears 22
Mutually hinged, the other end is each passed through the through slot of corresponding above-mentioned movable sleeve 21, rotatable installation respectively in above-mentioned movable sleeve 21
There is the gear being meshed with corresponding above-mentioned rack gear 22, two above-mentioned movable sleeves 21 (the same side) are separately installed with and its inner teeth
Take turns the knob 23 of transmission connection, any one the above-mentioned rotation of knob 23 of outer power drive or two above-mentioned 23 synchronous backwards of knob of driving
Rotation, above-mentioned knob 23 drive corresponding gear to rotate, so that corresponding above-mentioned rack gear 22 is mobile relative to said gear, in turn
It adjusts two above-mentioned spanners 1 and rotates close angle, entire 2 structure of the adjuster design that limits is very ingenious, in use process, in advance
Two rack gears 22 are first each passed through to the movable sleeve 21 of two spanners 1, meanwhile, movable sleeve 21 is closed along the torque that handle 12 slides
The clamping part 11 of two spanners 1 is stuck in outside two threaded joint screws, next, can be single by suitable position in next step
The knob 23 on a movable sleeve 21 is solely turned, so that gear rotation band carry-over bar is mobile, so that the handle of two spanners 1
12 relative movements are close, two knobs 23 can also be reversely rotated simultaneously, so that the gear inside two movable sleeves 21 is reversely same
Step rotation, to drive two rack gears 22 to stretch, so that 12 relative rotation of handle of two spanners 1 is close, and then to two
Threaded joint screw carries out pretensioning operation, is difficult to directly to pass through gripping handle 12 particularly suitable for a small range operating personnel and rotates and pulls
The Job Operations that hand 1 pre-tightens realize low-angle and refinement.
Preferably, above-mentioned knob 23 includes connecting rod 231 and the turntable 232 for being fixed on above-mentioned 231 one end of connecting rod, above-mentioned company
The other end of bar 231 passes through the side of above-mentioned movable sleeve 21 and, entire knob 23 structure coaxially connected with corresponding said gear
Design is simple, and need to only turn turntable 232 can be realized the operation that knob 23 is rotated with moving gear, and save trouble and labor, operation is than very fast
It is prompt, conveniently.
Preferably, above-mentioned spanner 1 is monkey wrench, bayonet part 11 can be adjusted according to the model of practical threaded joint screw
The size of opening, very convenient, versatility is stronger.
It should be noted that: entire movable sleeve 21 can according to need skids off dismounting from the handle 12 of spanner 1, living
Dynamic set 21 can be plastic sheath or metallic sheath.
Illustrate: rack gear 22 when in use according to demand can arbitrarily from corresponding movable sleeve 21 remove or group
Dress, use are very 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.
