The drawing is given by figures 1 to 5, including opening rectangular shell 1 forward, be equipped with about the rectangle shell 1 the axial and rather than side wall fixed connection's spring 2 on it, the 2 lower extremes of spring are equipped with the light board 3 of horizontal direction, the 3 lower extremes of light board is fixed with the couple 4 that is located its central department, be equipped with in the rectangular shell 1 and be located its left side and be the baffle 5 of L shape, sliding connection has marking off board 6 between baffle 5 left side and the rectangular shell 1, it has marking off paper 7 to paste on the marking off board 6, set up the slide 8 of upper and lower direction on the baffle 5, the 3 left end of light board is equipped with the layer board 9 that inserts in the slide 8, through solid fixed ring 10 swing joint has the marking off pen 11 that can contact with marking off paper 7 on the layer board.

In order to keep the stability of the light plate 3 during measurement, the right side and the rear side of the rectangular shell 1 are respectively provided with a guide plate 12 in the vertical direction, each guide plate 12 is provided with a guide groove 13 which is in the vertical direction and is through inside and outside, the right end and the rear end of the light plate 3 are respectively fixed with a guide block 14 which extends into the corresponding guide groove 13, and the guide block 14 is in a T shape and extends between the guide plate 12 and the rectangular shell 1.

In order to record the measured data conveniently, the outer sides of the slide way 8 and the guide groove 13 are provided with gravity scales.

In order to facilitate the equidistant movement of the scribing plate 6, the lower end of the scribing plate 6 is provided with a plurality of grooves 15 which are uniformly distributed along the front-back direction, and the lower end of the partition plate 5 is provided with a plurality of lugs 16 which are in one-to-one correspondence with the grooves 15 and can be inserted into the grooves 15.

In order to conveniently place a heavy object for a test, a layering plate 17 in the horizontal direction is arranged on the lower side of the rectangular shell 1, a drawer 18 is connected between the layering plate 17 and the bottom of the rectangular shell 1 in a sliding mode, a sponge 19 is arranged in the drawer 18, a plurality of grooves 15 which are different in size and have upward openings are formed in the sponge 19, and weights 20 which are the same as the grooves 15 in shape are arranged in each groove 15.

For the convenience of teaching and observation, the rectangular shell 1 and the guide plate 12 are both made of transparent materials.

When the utility model is used, firstly, the marking paper 7 is pasted on the marking plate 6 through the transparent adhesive tape, the marking plate 6 is pushed to the rear side, then the marking pen 11 is inserted into the fixing ring 10 on the supporting plate 9, so that the end part of the marking pen 11 is just contacted with the marking paper 7, the marking pen 11 is tightly connected with the fixing ring 10 to keep stable, and the end part of the marking pen 11 is softer, and the friction force between the marking pen 11 and the marking paper 7 is extremely small and can be ignored;
