By arranging the square plate 5, the measuring device body 1 can be controlled to move to both sides by rotating the rotating handle 6, so as to stretch and measure the measuring tape 2. The interior of the first slide groove 17 is connected with the cylindrical groove 7, so that the gear 19 can contact the long tooth plate 18, and the outer surface of the gear 19 is meshed with the outer surface of the long tooth plate 18, so that the gear 19 can drive the long tooth plate 18 to extend outward. The outer surface of the measuring device body 1 is symmetrically provided with pentagonal opening grooves 15, and the interior of the pentagonal opening grooves 15 is rotatably connected with a rotating rod 16, and the outer surface of the rotating rod 16 is fixedly connected to the outer end of the measuring tape 2, so that the measuring device body 1 can be moved to both sides to drive the measuring tape 2 to be stretched. The bottom end of the measuring device body 1 is symmetrically fixedly connected with a plurality of evenly distributed fixed feet 14, so that the device can be stably placed on a plane.
[0020] The limiting and fixing component includes a limiting plate 11, a through groove 13 is provided on the outer surface of the measuring device body 1, and the hand pressure rod 3 is slidably connected inside the through groove 13, and a pressing plate 8 is fixedly connected to one end of the hand pressure rod 3 close to the through groove 13, and the outer surface of the pressing plate 8 is slidably connected to the inside of the placement groove 4, and a plurality of evenly distributed limiting grooves 12 are provided on the outer surface of the hand pressure rod 3, and a second sliding groove 9 is provided on the outer surface of the measuring device body 1, and the second sliding groove 9 is slidably connected to the outer surface of the limiting plate 11, and a spring 10 is fixedly connected to the outer surface of the limiting plate 11, and the end of the spring 10 away from the limiting plate 11 is fixedly connected to the inner side of the second sliding groove 9.

[0021] Working principle: When it is necessary to measure the size, place the corner end of the bed sheet in the placement slot 4 and fix it. Then the staff can grab and turn the rotating handle 6. The rotating handle 6 drives the gear 19 to rotate in the cylindrical slot 7. The gear 19 drives the long toothed plate 18 to slowly extend to both sides, thereby pushing the measuring device body 1 to move to both sides, so that the side end of the bed sheet is slowly unfolded. At the same time, the measuring device body 1 moves to both sides to drive the measuring tape 2 to extend and the rotating rod 16 to rotate in the pentagonal opening slot 15. When the side end of the bed sheet is fully unfolded, the staff can stop turning the rotating handle 6 and then observe the scale of the measuring tape 2.
[0022] When the corner end of the sheet is placed in the placement groove 4, the staff can push the limit plate 11 to slide in the second slide groove 9 and squeeze the spring 10. The spring 10 contracts under the force to make the limit plate 11 move out of the limit groove 12. Then the staff can press the hand pressure rod 3 downward to make the hand pressure rod 3 move downward in the through groove 13. The movement of the hand pressure rod 3 drives the pressure plate 8 to press and fix the corner end of the sheet downward. Then the staff can release the hand that pushes the limit plate 11. Under the action of the spring 10, the limit plate 11 slides into the limit groove 12 to fix the hand pressure rod 3.
