Describe in the face of further technical scheme down:

On said bar head and bar tail, being provided with changes the hole, and said connector comprises attachment screw, attaching nut, has corresponding screw thread between attachment screw and the attaching nut, after attachment screw passes and changes the hole, said bar head and bar tail is flexibly connected.

The link of said bar head, bar tail has corresponding yoke and connector, and connector inserts in the yoke, and said commentaries on classics hole is located on yoke and the connector.

Certainly, the bar head can also adopt other version with being connected of bar tail.

Advantage or principle in the face of the aforementioned techniques scheme describes down:

1, owing to can relatively rotate between the bar head of knife bar and the bar tail, under the situation of the big revolving force of needs, can unclamp connector; The bar tail is rotated to 90 degree positions with respect to the bar head to be tightened again; At this moment, the people holds the bar tailspin to be changeed, and bigger revolving force can be provided;

2, under the narrower and small situation in operating space, also can the adjusting lever tail with respect to the angle of bar head, reduce the interference between screwdriver and other object, more convenient operation.
