The locking device comprises a sliding cavity, a sliding rod, a spring, a movable plate, a shifting plate, a connecting rod and a clamping block, wherein the sliding cavity is fixed on the outer wall of the inner shell, the sliding rod is arranged in the sliding cavity, the movable plate is arranged on the sliding rod, the movable plate and the sliding rod are connected in a sliding mode, one end of the movable plate is connected with one end of the spring, the other end of the spring is connected with the sliding cavity, the other end of the movable plate is connected with one end of the connecting rod, the other end of the connecting rod penetrates through the wall.
The utility model has the advantages that: 1. the auxiliary ruler can be pulled in the main ruler in a mode which is favorable for carrying; 2. when the auxiliary ruler is used, the auxiliary ruler can be pulled out of the main ruler, then the magnet A on the auxiliary ruler is connected to the magnet B in the main ruler, the ruler is lengthened, and when the magnet A on the auxiliary ruler is placed in the clamping device, the ruler is changed into a T-shaped ruler, so that the auxiliary ruler is more flexible to use, and the application range is wider.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a rear view of the main scale of the present invention.
Fig. 3 is a schematic structural view of the clamping device of the present invention.
Fig. 4 is a first usage state diagram of the present invention.
Fig. 5 is a second usage state diagram of the present invention.
The specific implementation mode is as follows:
the drawings are for illustrative purposes only and are not to be construed as limiting the patent; to better illustrate the present example, some components of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Referring to the figures, the multipurpose student mathematics ruler comprises a main ruler 1, wherein the main ruler 1 is rectangular, the front surface of the main ruler 1 is provided with a scale bar 5, the back surface of the main ruler 1 is provided with a sliding groove 7, an auxiliary ruler 3 is arranged in the sliding groove 7, the auxiliary ruler and the main ruler are in sliding connection, one end of the auxiliary ruler 3 is embedded with a magnet A4, the left side wall of the main ruler 1 is embedded with a magnet A4, and the top side wall of the main ruler 1 is internally provided with a clamping device 2.
The front surface of the auxiliary ruler 3 is also provided with a scale bar 5.
The number of the magnet A4 is not less than one, and the number of the magnet A4 corresponds to the number of the magnet B6.
The locking device 213 comprises a sliding cavity 205, a sliding rod 206, a spring 207, a moving plate 208, a shifting plate 209, a connecting rod 210 and a clamping block 211, the sliding cavity 205 is fixed on the outer wall of the inner shell 212, the sliding rod 206 is arranged in the sliding cavity 205, the moving plate 208 is arranged on the sliding rod 206 and is in sliding connection with the sliding cavity, one end of the moving plate 208 is connected with one end of the spring 207, the other end of the spring 207 is connected with the sliding cavity 205, the other end of the moving plate 208 is connected with one end of the connecting rod 210, the other end of the connecting rod 210 penetrates through the inner shell wall to be connected with the clamping block.
