Described holding frame comprises the U-shaped frame be fixed by socket in balance U-shaped opening side can with the fixed head driving connecting lever to be connected with one, the one-body molded root being fixed on U-shaped frame of fixed head; The setting of fixed head makes holding frame and drives connecting lever connected mode more flexible.
Be connected and fixed by bolts and nuts between described each holding frame and balance.
Described balance U-shaped opening both sides are respectively arranged at intervals with two longitudinal holes, and on the deckle board that described each U-shaped frame is upper and lower, corresponding longitudinal hole position is respectively provided with two location holes; Bolt inserts location hole and is locked on holding frame with being connected with nut after longitudinal hole; Balance is alignd stacked and between the spacing deckle board upper and lower at U-shaped frame, and balance can be made to slide up and down along bolt.
Described balance position of positioning hole corresponding between deckle board is provided with the buffer gasket that can pass for bolt; Balance is coordinated at U-shaped frame Elastic, increases elastic buffer space further.
The beneficial effects of the utility model are: balance entirety possesses elastic buffer merit, balance is connected to insulated tension pole and drives between connecting lever, the close a floodgate impact energy of moment of moving contact and fixed contact is made to obtain cushioning and discharge, eliminate closing rebound phenomenon, and by adjustment balancing patch and the stacked quantity of cushion pad to regulate balance weight, with the actual installation needs of the movable contact system of satisfied different current class.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of vacuum circuit-breaker is as shown in Figure 1 in transmission connection with buffer, mainly comprises a balance 10, two holding frames 20, four raised head bolts 30 and four nuts 40.
As shown in Figure 1, balance 10 of the present utility model to be alignd with the cushion pad 12 of some U-shapeds by the balancing patch 11 of some U-shapeds and stackedly to form, and each cushion pad 12 is sandwiched between two adjacent balancing patches 11; On the stacked direction of balancing patch 11 with cushion pad 12, each attaching one in balance 10U shape opening both sides can with the holding frame 20 driving connecting lever to be connected.Specifically: described balance 10U shape opening both sides are respectively arranged at intervals with two longitudinal holes 111; Described holding frame 20 comprises the U-shaped frame 21 be fixed by socket in the U-shaped opening side of balance 10 can with the fixed head 22 driving connecting lever to be connected with one, the one-body molded root being fixed on U-shaped frame 21 of fixed head 22; On the deckle board 211 that each U-shaped frame 21 is upper and lower, corresponding longitudinal hole 111 position is respectively provided with two location holes 212.
