The upper end portion of the limiting block block 36 is provided with a plurality of limiting latching teeth 361. The limiting latching teeth 361 are formed as a single inclined surface. The limiting latching block 36 is convexly provided with a pressing rod 362 and a positioning sleeve 37. A positioning inlay 370 is disposed in the positioning hole 370, and the positioning inlay 370 of the positioning sleeve 37 is embedded in the insertion hole 300 of the housing 30. The positioning bushing 37 is further provided with a latching tooth 371 corresponding to the limiting latching tooth 361 of the limiting latching block 36. The latching tooth 371 is also provided as a single inclined surface, and the positioning bushing 37 is provided with a through hole 372. The pressing rod 362 of the positioning block 36 is extended by the through hole 372 of the positioning sleeve 37, and a flexible screen 4 is wound in the chamber 30 of the retracting device 3, and the flexible screen 4 is One end of the flexible screen 4 is provided with a pull tab 40. The other end of the flexible screen 4 is provided with a pull tab 40, and an arc is fixed on the upper and lower edges of the back surface of the flexible screen 4. Metal Sheet 5, thus, is the fixing means of a flexible screen.

When assembling, please refer to the second to fourth figures. First, one end of the flexible screen 4 is disposed by the slot 310 of the reel 31 in the reel 31, and the positioning block 33 is disposed on the coil spring 32. The lower end portion, the support shaft 34 is inserted into the coil spring 32 from the through hole 330 of the positioning block 33, and the upper end portion of the coil spring 32 is fixed to one end portion of the support shaft 34, and the coil spring 32, the positioning block 33 and the branch are further supported. The shaft 34 is disposed in the lower end portion of the reel 31 so that the positioning protrusion 331 of the positioning block 33 is inserted into the lower end portion of the slot 310 of the reel 31, and the positioning block 33 is positioned at the lower end of the reel 31, and then the fixed shaft is fixed. The sleeve 35 is disposed at the lower end of the chamber 30. The fixing sleeve 35 is disposed on the other end of the positioning block 33 and the support shaft 34. The protrusion 340 of the support shaft 34 is disposed on the fixed sleeve. The positioning inlay 350 of the fixing sleeve 35 is embedded in the lower hole 301 of the cavity 30, and the fixing sleeve 35 is fixed to the lower end of the reel 31, and the limit is fixed. The block 36 is disposed at the upper end of the reel 31, so that the positioning protrusion 360 of the limiting block 36 is inserted into the upper end of the slot 310 of the reel 31, and the limiting block 36 is positioned on the reel 31. The positioning sleeve 37 is disposed on the upper end of the chamber 30, and the positioning sleeve 37 is disposed on the limiting block 36. The pressing rod 362 of the limiting block 36 is positioned by the positioning sleeve The through hole 372 of the 37 is extended outwardly, and the limiting tooth 361 of the limiting block 36 is engaged with the latch 371 of the positioning sleeve 37, and the positioning inlay 370 of the positioning sleeve 37 is embedded in the capacity. In the hole 300 above the chamber 30, the positioning sleeve 37 is fixed to the upper end of the chamber 30, so that the assembly can be completed.

When the flexible screen 4 is to be pulled out, please refer to the third and fourth figures, the pull tab 40 only needs to be pulled outward, and the flexible screen 4 is taken into the chamber 30 of the retracting device 3. When the reel 31 is pulled, the reel 31 rotates, and the reel 31 drives the positioning block 33 and the limiting block 36 to rotate. The rotation of the positioning block 33 causes the coil spring 32 to be elastically twisted, and the limit on the limiting block 36 is limited. The latching teeth 361 are in abutment with the latching teeth 371 of the positioning bushing 37, and the reel 31 can only be unidirectionally rotated in the direction in which the flexible screen 4 is pulled out, so that the reel 31 is positioned without being subjected to the coil spring. The elastic restoring force of 32 drives the flexible screen 4 to be smoothly pulled out, and the metal coil 5 on the back of the flexible screen 4 is straight as the flexible screen 4 is pulled out. The flexible screen 4 can be supported by the flat support of the metal coil 5 disposed at the upper and lower edges of the back surface, so that the flexible screen 4 is flat and does not have wrinkles, so no need to use one hand during use. Support the flexible screen 4 for easy operation.

If the flexible screen 4 is not in use, please refer to the fifth and sixth figures, and only the pressing rod 362 protruding from the positioning sleeve 37 is pressed into the positioning sleeve 37, so that the limit block can be made. 36 is moved down, and the limiting latch 361 on the limiting block 36 is disengaged from the latch 371 of the positioning sleeve 37, so that the limiting latch 361 and the latch 371 are no longer clamped to each other, and the reel 31 is subjected to the coil spring. The elastic restoring force of 32 drives the reverse rotation, and the flexible screen 4 is retracted into the chamber 30 of the retracting device 3, and the metal reel 5 on the back of the flexible screen 4 is wound on the reel 31. It is also very convenient and fast in the collection.

In summary, the present invention has achieved the intended use and effect, and is more desirable and practical than the prior art. However, the above embodiments are only specifically described for the preferred embodiment of the present invention.
