[0028] The right surface of fixed plate 3 is equipped with extension slot 18, extension slot 18 is communicated with right guide slot 6, two rotating shafts 10 are movably extended outside fixed plate 3 through extension slot 18.

[0029] The right side of two rotating shafts 10 is provided with pull plate 19, the side surface of pull plate 19 facing rotating shaft 10 is equipped with limiting slot 20, two rotating shafts 10 are movably sleeved in the inside of limiting slot 20.

[0030] The right surface of fixed plate 3 is fixedly connected with two guide rods 21, pull plate 19 is slidably sleeved on the outer surface of two guide rods 21, second spring 22 is fixedly connected between pull plate 19 and telescopic slot 13, and second spring 22 is movably sleeved on the outside of guide rod 21.

[0032] Left two guide blocks 7 are threadedly sleeved in the opposite threads of bidirectional screw rod 16.

[0033] The surface sleeve of the driving roller 5 is provided with a friction pad 501, and the friction pad 501 further increases the friction between the driving roller 5 and the measuring tape.

[0034] The upper surface of the base 1 is provided with a cleaning assembly 12, which is a prior structure, and the specific reference can be made to the prior art with the publication number CN221464493U, and the working principle thereof is known to those skilled in the art, so it will not be described herein.

[0035] Working principle:

[0036] When the building design measuring tool is used, the staff passes the excess of the measuring tape inside the measuring tape box 2 between the two driving rollers 5, and then rotates the knob 17, which drives the rotation of the bidirectional threaded rod 16, and the rotation of the bidirectional threaded rod 16 drives the sliding of the two left guide blocks 7 in the left guide groove 6, thereby driving the displacement of the two driving rollers 5 and the two right guide blocks 7, and finally realizing the clamping of the surface of the two driving rollers 5 and the measuring tape.

[0037] When the right guide block 7 moves, the rotating shaft 10 will also move synchronously, and at this time the rotating shaft 10 will slide in the extension groove 18, and at the same time the rotating shaft 10 will also slide in the limiting groove 20.

[0038] Subsequently, the measuring tape is passed through the cleaning assembly 12 arranged on the front side, and when the measuring tape needs to be used, the measuring tape is pulled, and at this time the cooperation between the friction pad 501 and the driving roller 5 drives the driving roller 5 to rotate when the measuring tape moves, and at this time the lower driving roller 5 rotates counterclockwise, and the upper driving roller 5 rotates clockwise, and the rotation of the driving roller 5 drives the rotation of the two connecting shafts 9, and because the rotating shaft 10 is sleeved in the right connecting shaft 9 through the sliding block, the rotating shaft 10 also rotates synchronously, and at this time the rotation of the rotating shaft 10 drives the rotation of the gear 11, and when the gear 11 rotates, the inclined surface of the gear teeth on the surface of the gear 11 will be in contact with the inclined surface of the movable gear teeth 14, thereby pushing the movable gear teeth 14 into the extension slot 13, and at this time the first spring 15 will be deformed, and when it is pulled to the appropriate position, the staff releases the measuring tape, and at this time the gear teeth on the surface of the gear 11 and the vertical surface of the movable gear teeth 14 will be in contact, thereby preventing the measuring tape from being reset by the clamping of the driving roller 5.

[0039] When the staff needs to reset the measuring tape, the staff pulls the pull plate 19 outward, and at this time the movement of the pull plate 19 drives the movement of the rotating shaft 10, and the movement of the rotating shaft 10 drives the movement of the gear 11, and at this time the gear teeth on the surface of the gear 11 will be separated from the movable gear teeth 14, thereby no longer limiting the driving roller 5, and at this time the elastic force of the measuring tape itself will make the driving roller 5 rotate.

[0040] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the present application, which should be limited only by the appended claims and their equivalents.
