Furthermore, first ear seat and second ear seat are half-round type structure, and first ear seat and second ear seat pass through bolt fixed connection and form the cylinder type cavity, be equipped with the cylindric lock in the cylinder type cavity, be equipped with the third recess that supplies the parallel key installation on the cylindric lock.
Furthermore, a first rubber pad is arranged between the cylindrical pin and the first lug seat, and a second rubber pad is arranged between the cylindrical pin and the second lug seat.
Furthermore, a plurality of groups of first threaded holes are formed in the flat key, and a plurality of groups of second threaded holes corresponding to the first threaded holes are formed in the cylindrical pin.
Furthermore, equal threaded connection has a locking screw on first ear seat and the second ear seat, locking screw's one end fixedly connected with bulb.
Has the advantages that: the utility model can prevent the first ear seat and the second ear seat from rotating relative to the cylindrical pin through the flat key, and meanwhile, rubber pads are arranged between the cylindrical pin and the first ear seat and the second ear seat, thereby effectively reducing the abrasion speed of the cylindrical pin and the ear seats; the clamping force between the cylindrical pin and the lug seat can be adjusted by the locking screw, so that the locking screw is very flexible to use, and the abrasion between the cylindrical pin and the lug seat is reduced. The utility model discloses reliable practicality is strong, and it is required to satisfy the site production completely.
