Description

An English teaching marking device

technical field

The utility model relates to an English teaching device, in particular to a marking device.

Background technique

In the early stage of English teaching, underlining is needed to teach students how to write in English. Although electronic teaching has become more and more common now, in order to increase the interaction and randomness of the classroom, the pen is still an indispensable thing. When using stroke lines, tools are needed to make the lines neat and the distance between each line constant. There are two common scribing tools: 1. A flat plate with four grooves on it. When using it, manually slide the pen along the grooves. This device has a simple structure, but the sliding of the flat plate makes the scribing lines non-parallel when used. Or the distance between the lines is not fixed; 2. A skateboard drives four pens to move at the same time, and can quickly draw four straight lines, but the disadvantage is that the skateboard cannot be fixed, and manual stabilization is also required.

Utility model content

The utility model proposes a marking device for English teaching, which can draw four straight lines at the same time, and the device can be fixed without affecting the use of observers.

The utility model is realized in the following way: an English teaching marking device, including a bracket, a horizontal chute is arranged on the bracket, a T-shaped slider is matched with the horizontal chute, the T-shaped slider is connected with a sliding plate, and the sliding The board is connected with the pen holder, and the back of the support is provided with a fixed frame, which forms a U-shaped groove with the support, and the fixed frame is connected with a first jacking bolt.

The sliding plate is provided with a vertical chute for the pen holder to slide, and the chute is provided with a second tightening bolt.

The bracket is provided with scale lines.

The T-shaped slider is provided with a threaded hole, and the top of the sliding plate is provided with a through hole, and the T-shaped slider and the sliding plate are connected by fixing bolts.

When the utility model is used, it can be fixed on a blackboard or a whiteboard, so that the device will not shake during the marking process, so that the obtained straight line meets the requirements. Moreover, the device is easy to carry and does not affect the user's line of sight.
