This utility model discloses a
single crystal rod clamping mechanism, including a base, a
threaded rod mounted on the base via bearings, a rotating disk fixedly mounted on the right end of the
threaded rod; a guide post fixedly mounted inside the base; a moving block screwed onto the outside of the
threaded rod; a fixing sleeve fixedly mounted above the moving block, with an insert post fixedly mounted inside the fixing sleeve; an
insertion rod inserted into the inside of the fixing sleeve, with a connecting block fixedly mounted between the
insertion rod and a clamping ring; a first limiting
assembly mounted on the side of the fixing sleeve, comprising a first track, a first T-shaped slider, a connecting block, an end plate, a spring, a
handle, a screw, and a threaded sleeve; and a support plate fixedly mounted above the base. This mechanism facilitates the disassembly of the clamping ring and allows for replacement with clamping rings of other sizes, enabling the product to clamp
single crystal rods of different sizes, thus minimizing limitations and broadening its applicability.
