Specifically, as shown in fig. 2, the measuring part 12 may be, for example, a scale, and the measuring part 12 is closely attached to a side surface of the body 10 for displaying a measurement result. The positioning member 30 comprises a groove adapted to receive the side plate 2, the groove comprises a first side wall 321 and a second side wall 322 opposite to the first side wall 321, as shown in fig. 1, the side plate 2 is located between two side walls of the groove of the positioning member 30, and the direction in which the body 10 extends upwards is perpendicular to the direction of the top end plane of the side plate 2, so as to ensure the accuracy of the measurement. As shown in fig. 2, the slider 20 may be, for example, an L-shaped slider, and the side plate 2 is fixed in the groove at the time of measurement, and the top end of the side plate 2 abuts against the inner end surface 323 of the groove, and at the same time, the horizontal surface 22 of the bottom end of the slider 20 abuts against the top end of the coil 2. Therefore, before the measurement starts, the horizontal surface 22 of the bottom end of the sliding member 20 is ensured to be parallel to the inner end surface 323 of the groove of the positioning member 30, and the initial position (first position) of the sliding member 20 relative to the body 10 at this time can be obtained and recorded by the reading of the measuring portion 12; during the measurement, the sliding member 20 is moved downwards until the horizontal surface 22 of the bottom end of the sliding member 20 abuts against the top end of the coil 2, and the reading of the measuring part 12 can obtain and record the position (second position) of the sliding member 20 relative to the body 10 at this moment, and obviously, the difference between the second position and the first position is the height difference between the top end of the coil 1 and the top end of the side plate 2.
