[0002] The abacus counter, usually also known as the primary school student counter, is a mathematical auxiliary tool designed specifically for primary school students. It mainly includes counting beads and an arched bead threading rod. There are a "tens place" and a "units place" on this counter. One bead in the tens place represents 1 ten, and one bead in the units place represents 1 one. There are 10 beads respectively in the tens place and the units place, which can be used to represent different numbers.

[0003] Currently, students count by moving the beads to the other part of the arched bead threading rod and then according to the unit and the corresponding beads in the corresponding position. However, during the use of the abacus counter, its weight is relatively light and it is prone to falling or tipping over when being collided externally. Moreover, the counting beads are movable, so the positions of the beads that have been moved may be disrupted, thus affecting the accuracy of counting. Therefore, a student counter is proposed.

After moving, under the action of the spring 64, the abutting blocks 63 move upward again. When re-counting is needed, the knob 54 can be rotated by hand, so that the moving block 51 moves downward in the inner cavity of the built-in groove 42, and multiple abutting blocks 63 move downward simultaneously, so that the abacus beads 3 at both ends of the bead threading rod 2 can communicate with each other, thereby re-adjusting the positions of the abacus beads 3. When it is necessary to assemble two devices together, the side plates 73 on the corresponding sides of the two devices can be disassembled, and then the two devices can be connected together through the plug board one 72 and the slot one 71 for use.
