Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The novel device for rapidly assembling the butterfly-shaped elastic sheet shown in fig. 1-3 comprises a butterfly-shaped elastic sheet support 1 and a copper sleeve 2, and is characterized in that the butterfly-shaped elastic sheet support 1 comprises a support front end 11 and a support rear end 12, the support front end 11 is provided with a threaded hole 13, the support rear end 12 is provided with a first through hole 14, the threaded hole 13 and the first through hole 14 are perpendicular to each other, the copper sleeve 2 is provided with a cavity 21 along the axial direction, one end of the cavity 21 is provided with a first limiting edge 22, one end of the copper sleeve 2 close to the first limiting edge 22 is provided with a second through hole 23 along the radial direction, a pin 3 is inserted between the first through hole 14 and the second through hole 23, the first limiting edge 22 and the edge of the support rear end 12 form interference, the support front end 11 is sleeved with the butterfly-shaped elastic sheet 4, the copper sleeve 2 is sleeved in a shaft sleeve 5, the outer wall of one end of the shaft sleeve 5 is provided, the other end inner wall is equipped with the spacing edge 52 of second, support front end 11 still is equipped with and presses cover 6, press the cover 6 and attack internal thread 61 near the one end inner wall of axle sleeve 5 partially, external screw thread 51 and internal thread 61 phase-match, press cover 6 to keep away from the one end middle part of axle sleeve 5 and seted up third through-hole 62, clearance fit can be formed with the external diameter of support front end 11 in third through-hole 62 aperture, screw hole 13 still is equipped with screw 7, the nut of screw 7 can form with the edge of third through-hole 62 and interfere.
