[0035] Furthermore, the positioning mechanism includes a plurality of stoppers 32 disposed inside the frame 1, and a plurality of slots for inserting the stoppers 32 are provided inside the frame 1;

[0036] Furthermore, the retraction mechanism includes a control sleeve 34 arranged on the outer wall of the frame 1, a first spring 31 is connected between the stop block 32 and the groove cavity, and a movable rod is fixed on the top of the stop block 32, the movable rod extends to the outer wall of the frame 1 and is connected to the control sleeve 34, the first spring 31 is sleeved on the outer wall of the movable rod, and a limiting mechanism for limiting the stop block 32 is arranged between the stop block 32 and the groove cavity, and the limiting mechanism includes limiting grooves opened on both sides of the groove cavity, and limiting blocks 33 corresponding to the limiting grooves are fixed on both sides of the stop block 32.

[0037] When the ruler body 5 is being rolled up, the stopper 32 and the baffle plate 35 are arranged so that the ruler body 5 and the protective shell 2 can be positioned inside the frame body 1;

[0038] When the ruler body 5 needs to be replaced or disassembled, the control sleeve 34 is first pulled to drive the movable rod to move, and the movement of the movable rod drives the stopper 32 to move, and the movement of the stopper 32 drives the first spring 31 to contract, and the contraction of the first spring 31 causes the stopper 32 to enter the groove cavity. When the stopper 32 enters the groove cavity, it is separated from the protective shell 2, and the stopper 33 cooperates with the limit groove to make the stopper 32 more stable during the movement and will not easily deviate;

[0039] Then, the control rod 38 is pulled to drive the plug block 36 to move, and the plug block 36 is separated from the plug hole through the movement. After the plug block 36 and the plug hole are separated from each other, the baffle plate 35 is pulled to move through the cooperation between the convex strip and the slide groove, until the baffle plate 35 is separated from the opening groove, and the protective shell 2 is pulled to drive the ruler body 5 to move synchronously, so that it is separated from the frame body 1, so as to realize the disassembly operation of the ruler body 5;

[0040] Through the elastic force of the first spring 31 and the second spring 37 , the stopper 32 and the baffle plate 35 can respectively position the protective shell 2 and the ruler body 5 , thereby forming a reinforcement effect on the protective shell 2 and the ruler body 5 .

[0042] When the ruler 5 is telescopically moved, the roller 42 is arranged to prevent it from easily rubbing against the outer wall of the frame 1, and at the same time, the movement of the ruler 5 can be smoother. When the ruler 5 contracts and drives the block close to one side of the frame 1, the movable plate 43 is rotated to drive the protective plate 44 to rotate synchronously, until the protective plate 44 is rotated to a position corresponding to the block, the block can be blocked to prevent it from contracting excessively and entering the inside of the frame 1, so that the utility model has more recyclability.
