The clamping block 15 rotates with the winding shaft 13, and it is convenient for the winding shaft 13 to be disassembled and assembled with the cylinder body 1. The clamping block 15 is clamped at one end of the lower cover 11 and the upper cover 12. The end surface of the clamping block 15 is provided with a groove, and the inner wall of the groove is provided with a bearing 14 and a coil spring 16. One end of the coil spring 16 is fixedly connected to the surface of the winding shaft 13, and the winding shaft 13 can be automatically rotated and wound by the elastic force of the coil spring 16. The inner ring of the bearing 14 is fixedly sleeved with the winding shaft 13, and the surface of the winding shaft 13 is fixedly connected. A drawstring 17 is connected, and the length of the drawstring 17 is smaller than the length of the opening 18. The drawstring 17 is made of a flexible plastic sheet. The drawstring 17 facilitates the clamping seat 2 to be pulled out of the cylinder 1, and is also convenient for winding and unwinding. One end of the drawstring 17 is fixedly connected to the clamping seat 2, and the surface of the clamping seat 2 is telescopically connected with a symmetrical positioning block 22. The positioning block 22 can prevent the winding shaft 13 from automatically rotating and winding to pull the clamping seat 2 into the cylinder 1, so as to facilitate the positioning of the drawing 3 after being pulled out, and facilitate the user to modify the drawing And replacement, one end of the positioning block 22 is in contact with a spring 24, a clamping plate 26 is provided on the side of the clamping seat 2, the clamping plate 26 and the clamping seat 2 form a clamping groove 25, the inner wall of the clamping groove 25 is in contact with and connected to multiple drawings 3, the other end of the drawing 3 is plugged with a pull rod 41, the pull rod 41 is convenient for connecting with one end of the drawing 3, and it is convenient to flip through the drawings 3, the surface of the pull rod 41 is connected to the pull seat 4 through a thread, the surface of the pull seat 4 is sleeved with a sealing gasket 43, and one side of the pull seat 4 is fixedly connected with a pull plate 44.

[0026] A slope 28 is provided at one end of the positioning block 22, and the other end of the positioning block 22 is fixedly sleeved with a limit plate 23. A mounting groove 21 is provided inside the clamp seat 2, and the inner wall of the mounting groove 21 is in contact and connected with the side of the limit plate 23. The slope 28 facilitates that when the clamp seat 2 is pulled out of the opening 18, the inner wall of the opening 18 contacts the slope 28, so that the positioning block 22 automatically shrinks. Concentric and coaxial bolt holes are provided on the surfaces of the clamp plate 26 and the clamp seat 2, and bolts 27 are sleeved on the inner walls of the bolt holes.

[0028] When the portable storage tube for surveying and mapping geographic information drawings needs to unwind and pull out the drawing 3, the user manually grasps the pulling plate 44 and pulls the drawing 3 to the right. The drawing 3 moves to the right so that the pulling seat 4 is separated from the opening 18 to the right. When the drawing 3 continues to be pulled to the right out of the opening 18, the clamping seat 2 is driven to move to the right and extend out of the tube body 1 from the opening 18. At this time, the drawing 3 is stopped from being pulled to the right. At the same time, the elastic force of the winding spring 16 drives the winding shaft 13 to rewind the drawing 3 to the left. At this time, the surface of the positioning block 22 that automatically pops up contacts the surface of the tube body 1, causing the clamping seat 2 to stop moving. Move left to locate the position of drawing 3, then separate the reinforcing ring 31 at one end of drawing 3 from the pull rod 41 and flip through it. The provided pull belt 17, clamp seat 2 and positioning block 22 not only facilitate the rapid installation and replacement of multiple drawings 3, but also facilitate automatic positioning after all drawings 3 are pulled out, greatly improving the convenience of use.
