ABSTRACT:
An elastic connector for holding mechanical parts firmly includes a base to accomodate an S-shaped spring piece and one unit of symmetrical steel sheets. On the upper direction of the base a supporting member is set to support the revolving of the control member, of which the two control rods are inserted into the S-shaped spring piece, while two fixing rods keep the steel sheets in a U-shaped condition. The upper direction of the control member is sealed by a lid which is fixed by a pair of rivets, only leaving a handle on the upper direction of the lid for operation purpose. When a spanner is sleeved onto the handle to revolve the control member, the two control rods of which will sandwich the two end plates of the S-shaped spring piece and drive them to move outward to enable the three holes to be arranged in a slanting formation, so as to produce a tightly squeezing function when passing through the outer wall of the rod member of the S-shaped spring piece, so as to hold the two firmly together. Owing to their sideward movement the other two fixing rods will release the control they exerted over the steel sheet, and thus enable the steel sheets to recover their L shape and squeeze tightly against the fixing rod, so as to prevent the control member from loosening.
