A combinative cutter includes a holder, a shank, a blade and at least two screws. The holder includes an eccentric bore defined at an end and at least two screw holes in communication with the eccentric bore. The shank is inserted in the eccentric bore and formed with a planar face. The blade is attached to an end of the shank extending beyond the holder. The screws are driven through the screw holes and abutted against the planar face to keep the shank in the eccentric bore.

A single chip Z-axis linear magnetoresistive sensor with a calibration / initialization coil comprises a single chip Z-axis linear magnetoresistive sensor, and a calibration coil and / or an initialization coil. The calibration coil and the initialization coil are planar coils or three-dimensional coils. The planar coils are located above a substrate and below a magnetoresistive sensing unit, between a magnetoresistive sensing unit and a soft ferromagnetic flux concentrator, above a soft ferromagnetic flux concentrator, or in a gap of the soft ferromagnetic flux concentrator. The three-dimensional coil is wound around the soft ferromagnetic flux concentrator and the magnetoresistive sensing unit. The calibration coil and the initialization coil respectively comprise straight wires which are parallel to a magnetization direction of a pinned layer / free layer, wherein the calibration coil generates an equivalent calibration magnetic field parallel / anti-parallel to the direction of the pinned layer of a push or a pull magnetoresistive unit string, and the initialization coil generates a uniform initializing magnetic field in the direction of the free layer at all magnetoresistive sensing units. By controlling the current in the calibration coil / initialization coil, calibration and magnetic state initialization of the single chip Z-axis linear magnetoresistive sensor can be achieved. The sensor has advantages of being highly efficient, quick, and convenient.

The invention discloses an auxiliary tool for detecting the precision of the adhesive tool and a detection method. The auxiliary tooling for detecting the accuracy of the adhesive tooling includes: a supporting base plate, which is in the shape of a rectangular plate; and inspection iron bars, which are vertically arranged on the left and right sides of the front end of the supporting base plate. When on the support plate of the adhesive tooling, the inspection iron bar is at the same height as the positioning bar of the adhesive tooling. The auxiliary tooling for detecting the accuracy of adhesive tooling can realize efficient inspection of the accuracy of adhesive positioning tooling, improve the inspection efficiency, and ensure the consistency of accuracy inspection of different adhesive positioning tooling, so as to solve the complicated steps and low efficiency of existing inspection methods , low precision and other issues.

The invention discloses a press-out-type antiskid visual easy-to-mark grid counting surface sampling culture dish which comprises a dish bottom and a dish cover. The dish bottom is provided with a second clasp and a first clasp which are in a stable chimeric structure. The chimeric structure can be loosened when a force is applied, so that a movable dish bottom side wall moves relative to a firstdish bottom side wall. When multiple culture dishes are stacked and placed, a first bulge and a second bulge can limit the relative movement of two adjacent culture dishes. A marking area makes marking more efficient. An observation window facilitates the observation of minute colonies, and grid lines simplify the counting process of bacterial colonies..
