Abstract
The invention discloses a suction plate line drawing device and relates to the technical field of teaching instruments. The suction plate line drawing device comprises a blackboard and a ruler. The blackboard is provided with a second suction plate, the ruler is fixed to the suction plate, the suction plate is connected to one end of an equal-length rope, and the other end is provided with a gasket. The suction plate line drawing device can solve the problem that a transverse line is not easy to control and prone to inclining during the drawing of a blackboard newspaper in the prior art.
Description
Technical field
The present invention relates to technical field of teaching instruments, especially a kind of sucker line-plotting device.
Background technology
Article, when making blackboard newspaper, first with long chi frame on blackboard, and then is copied on grid by school, office, because blackboard is laterally longer, the ruler of frame also will be grown, and longer ruler people is not easy to control, and causes the grid drawn not straight.
Summary of the invention
The object of this invention is to provide a kind of sucker line-plotting device, it can solve the problem that the long chi of prior art is drawn the very difficult control of blackboard newspaper horizontal line, caused setting-out crooked.
In order to solve the problem, the technical solution used in the present invention is:
A kind of sucker line-plotting device, comprise blackboard, ruler, described blackboard is provided with two suckers, described ruler is fixed on described sucker, and described sucker is connected with one end of isometric rope, and its other end is provided with packing ring.
Further: described sucker is vacuum cup.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, adopt the present invention to draw blackboard newspaper grid, long ruler easily controls, and the line drawn is both flat and straight;
2, structure of the present invention is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is further described: as shown in Figure 1,
A kind of sucker line-plotting device, comprises blackboard 3, ruler 2, blackboard 3 is provided with two suckers 1, and ruler 2 is fixing on the suction cup 1, and sucker 1 is connected with one end of isometric rope 5, and its other end is provided with packing ring 4; Sucker 1 is vacuum cup.
During setting-out, measure the distance of packing ring 4 apart from blackboard base with short chi, when survey measurements is identical, namely ruler 2 is in level.
