Problems solved by technology

[0004] but figure 1 When the microtome is working, the sample fixing mechanism cannot be retracted after one cut. During the upward movement of the sample fixing mechanism with the moving seat 2, the blade will contact the sample, which is prone to sticking to the knife, which not only damages the sample, but also easily Reduced blade life

Abstract

The invention discloses a retracting mechanism of a slicing machine. The retracting mechanism comprises an elastic piece, a retracting control block, a fixed disk, a sliding limiting piece, an upper jacking block and a lower jacking block; the elastic piece is located between a mounting plate and a limiting ring; the retracting control block is externally sleeved on a lead screw; one side of the retracting control block is hinged to the mounting plate; the fixed disk is fixed relative to the lead screw; the sliding limiting piece is provided with a groove matched with a control rod of the retracting control block; the depth of the upper part of the groove is greater than that of the lower part of the groove; the upper jacking block is used to allow the control rod to be located at the upper part of the groove; and the lower jacking block is used to allow the control rod to be located at the lower part of the groove, and drives the retracting control block to rotate. According to the retracting mechanism, after a movable seat moves down to the lowest point, the lead screw can be retracted, blade sticking is prevented, and a sample and a blade can be protected effectively.

Description

technical field [0001] The invention relates to a biological tissue slicer, in particular to a retracting mechanism of the slicer. Background technique [0002] In the middle of the last century, with people's continuous understanding and research on diseases, in addition to diagnosing diseases from gross tissues with the naked eye, it is also necessary to diagnose diseases from tissue structure and cell changes, which requires biological tissues to be made into thin slices of about 5um. Observe under a microscope, thus producing a microtome of biological tissue, the biological tissue is set on the embedding frame by paraffin, then the embedding frame is installed on the chuck of the embedding frame, and sliced ​​by the blade. [0003] Such as figure 1 Shown is a schematic diagram of the existing slicer, the mobile base 2 is slidingly arranged on the machine base 1, and the mobile base 2 can be controlled to reciprocate on the machine base 1 along the direction A through th...
