Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 7, a steel tape with a marking mechanism comprises a tape main body 1 and a marking mechanism 2 arranged on the tape main body 1, wherein the marking mechanism 2 comprises a main body seat 3 fixed with the tape main body 1, a pen core hole 4 longitudinally penetrating the whole main body seat 3 is arranged on the main body seat 3, the pen core hole 4 comprises a notch section 40 arranged at an upper position, and a friction wheel 5 opposite to the outlet is rotatably arranged at the outlet of the pen core hole 4; the slide tape comprises a tape measure main body 1 and is characterized by further comprising a slide block 6, wherein a pressing piece 7 used for pressing a pen core is fixed on one side of the slide block 6, a sliding groove 8 used for enabling the slide block 6 to slide is arranged on the shell of the tape measure main body 1, the sliding groove 8 comprises a vertical part 80 parallel to the pen core hole 4 and a bending part 81 bending towards the side far away from the pen core hole at the upper end of the vertical part 80, and an elastic belt mechanism 9 is arranged below the main body seat 3 and connected with the slide block 6 and used for providing the slide block 6 with the downward sliding pulling force; when the sliding block 6 slides along the vertical part to the bent part of the sliding groove 8, the pressing piece 7 fixed on one side of the sliding block 6 slides along the refill hole 4 and is separated from the refill hole 4 along the notch section 40.

When the structure is used, firstly, the sliding block 6 slides to the bending part 81 along the vertical part 80 of the sliding chute, and at the moment, the pressing piece 7 arranged on the sliding block 6 is separated along the gap section 40 of the refill hole 4, so that a refill can be inserted (or the inserted refill can be withdrawn) along the opening at the upper end of the refill hole 4; when the pen core is inserted into the pen core hole 4, the sliding block 6 slides to the vertical part 80 along the bending part 81 of the sliding groove, under the action force of the elastic belt mechanism 9, the pressing piece 7 on the sliding block 6 is pressed at the upper end of the pen core at the moment, so that the pen core is pressed between the pressing piece 7 and the friction wheel 5, when the pen core needs to be scribed, the friction wheel 5 is pressed at the position of a plane needing to be scribed, then the friction wheel 5 is rolled, the friction wheel 5 grinds the end part of the pen core to form pen core particles for mathematics, the pen core particles are uniformly distributed on the surface of the friction wheel 5, and the pen core particles are uniformly coated on the plane needing to be scribed along with the rotation of the friction wheel 5.

Wherein, in order to make it possible to grind the portion of the pen core end into pen core particles when the friction wheel 5 rotates, teeth are provided on the surface of said friction wheel 5. Specifically, the elastic band mechanism 9 is a coil spring.
