Problems solved by technology

[0003] One hand shakes when holding the test tube in a tilted state, and the other hand pinches the rubber-tip dropper instrument. The two cannot be controlled at the same time, resulting in contact between the end of the rubber-tip dropper and the end of the test tube, or The force of the rubber dropper is too large, and when moving the glass instrument support on the test bench, because the test bench is usually laid with a rubber table top, when the support is moved on the desktop, the friction between the support base and the desktop is large, and the support is dumped. On the experimental table, the glass instrument is damaged. These unfamiliar operations will lead to damage to the glass instrument or the failure of the experiment.

Abstract

The invention belongs to the technical field of experimental benches, and specifically relates to an educational management training experimental bench, which includes an experimental table and a stable clamping unit on the experimental table; the stable clamping unit includes a slider, a vertical bar, a horizontal bar, and a sliding bar and the clamping arm; a platform is provided on the front side of the upper end of the experimental table, and a chute is provided on the platform, and the chute is provided along the length direction of the experimental table. The sliding block is connected on the rod; the sliding block is U-shaped, and the sliding block is buckled on the sliding rod. The other end of the rod is connected to one end of the cross bar, and the other end of the cross bar is connected to the clamping arm; the clamping arm is slidably connected to the cross bar through fastening bolts, and the clamping arm is provided with a plurality of placement holes, and the placement holes Apertures vary in size, and the holes are used to place experimental instruments.

Description

technical field [0001] The invention belongs to the technical field of experimental benches, in particular to an educational management training experimental bench. Background technique [0002] In order to improve students' hands-on ability and combine theoretical knowledge with practice, the school provides laboratories for students. Students generally start learning chemistry in junior high school. Students get in touch with various bottles in the laboratory at the beginning. Cans of glass instruments used in chemical experiments, not proficient in operating glass instruments. [0003] One hand shakes when holding the test tube in a tilted state, and the other hand pinches the rubber-tip dropper instrument. The two cannot be controlled at the same time, resulting in contact between the end of the rubber-tip dropper and the end of the test tube, or The force of the rubber dropper is too large, and when moving the glass instrument support on the test bench, because the tes...
