It is hinged in the middle part of bar with the baffle plate other end, described drag-line one end is arranged on the gangbar other end.Drag-line is pulled during use, drag-line is drawn
The dynamic gangbar other end drives the end motion of gangbar one, and gangbar one end drives left clip tooth end inwardly to move, left clip tooth top
Moved out under lever principle, now right clip tooth end is fixed in baffle plate, and be open left and right clip tooth relative motion, and opening is beaten
Open and include cable in space at the top of the clip tooth of left and right, loosen drag-line, in folder axle in the presence of torsion spring, left and right clip tooth is closed again
Hold together, all resets.Now ammeter can obtain the current data inside cable, complete the collection of current data.Complete electricity
After the collection of flow data, drag-line is tensed, repeats the mechanism kinematic of the above, you can complete overall operating process.
Preferably, described baffle plate and described right clip tooth junction are additionally provided with holding screw.Holding screw can be with
Right clip tooth end is fixed on baffle plate, increases reliability of the present utility model.
Preferably, described described opening is arranged on left clip tooth side.Because when in use, user can typically incite somebody to action
The utility model from bottom to top stretch cable, if opening up, it is possible to the self falling when releasing, and be open in side
Design be not easy when can ensure to release self falling injure by a crashing object, smash near people and article.
Preferably, described opening caves inward.The opening design to cave inward can make cable be easier to be included into
In space among the clip tooth of left and right.
Preferably, the described gangbar other end is additionally provided with linkage groove, described left clip tooth end is additionally provided with connection
Dynamic bolt is engaged with linkage groove.The design of linkage bolt and the groove that links can make left clip tooth in the course of the work from gangbar
The probability released declines.
Preferably, being additionally provided with stopper slot on described baffle plate, described trace one end is additionally provided with sliding block and limit
Position groove is engaged.The design of sliding block and stopper slot adds reliability of the present utility model.
Therefore, adjustable tong-type ammeter of the present utility model possesses following advantages：Left and right clip tooth, folder axle, linkage
The design of bar, baffle plate, ammeter and drag-line completes clamping cable, measures a series of functions of electric current.Holding screw can incite somebody to action
Right clip tooth end is fixed on baffle plate, increases reliability of the present utility model.And the design being open in side can ensure to release
When be not easy self falling injure by a crashing object, smash near people and article.The opening design to cave inward can make cable be easier quilt
Include in the space among the clip tooth of left and right.The design of linkage bolt and the groove that links can make left clip tooth in the course of the work from linkage
The probability released on bar declines.
