Further, as shown in fig. 1 and 2, the measuring plate 121 is provided with a sliding groove 1211, the sliding groove 1211 is in a strip shape and is arranged along the extending direction of the measuring rod 122, and the sliding block 1313 is movably arranged in the sliding groove 1211; the side edges of the slide slot 1211 are provided with graduation marks 1212.

Specifically, one end of the screw rod 1312 far away from the sleeve 1311 is fixedly connected with a slide block 1313, correspondingly, the measuring plate 121 is provided with a slide groove 1211, and the width dimension of the slide block 1313 is matched with the slide groove 1211, so that the slide block 1313 can be slidably arranged in the measuring plate 121; the side edge of the slide 1211 is provided with a row of graduation marks 1212, the graduation marks 1212 being arranged along the direction of relative movement of the slide 1313 and the slide 1211.

It should be noted that, in a preferred embodiment of the present application, as shown in fig. 1, the sliding block 1313 has an oval structure with upper and lower sides adapted to the sliding groove 1211; of course, the slider 1313 may be a rectangular block other than an oval structure, as long as it can be adapted to the slide slot 1211 and can be slidably disposed, which is not limited in any way.
