[0049] The support assembly 3 includes: a limiting rod 301, a bidirectional lead screw 302, a movable frame 306, a support rod 307, and a support base 308. There are two limiting rods 301, both of which are fixedly connected to the inside of the fixed base 1. The bidirectional lead screw 302 is rotatably connected to the inside of the fixed base 1. One end of the bidirectional lead screw 302 is fixedly connected to a fixed plate 303. A crank 304 is fixedly connected to one side of the fixed plate 303. A grip tube 305 is rotatably connected to the outside of the crank 304. The movable frame 306 is fixedly connected to the outside of the limiting rod 301. There are two movable frames 306, which are threadedly connected to both ends of the bidirectional lead screw 302 respectively. One end of the support rod 307 is rotatably connected to the bottom end of the movable frame 306. The support base 308 is rotatably connected to the other end of the support rod 307. An anti-slip rubber membrane is fixedly connected to the bottom end of the support base 308.

[0050] Height positioning structure: limit block 501, hexagonal prism 503, button 504 and spring 505. Limit block 501 is slidably connected to the inside of guide groove 401. A storage groove 502 is opened on the side of limit block 501 near positioning hole 402. Hexagonal prism 503 is fixedly connected to the inside of storage groove 502. Button 504 is slidably connected to the inside of storage groove 502. Button 504 and hexagonal prism 503 are slidably connected. Spring 505 is sleeved on the outside of hexagonal prism 503 and fixedly connected between button 504 and storage groove 502.

[0051] The heat shrink film roll clamping and positioning structure includes: a connecting tube 506, a limiting shaft 508, a connecting ring 509, a second spring 510, a sleeve 511, a plug 513, and a retaining ring 514. The connecting tube 506 is fixedly connected to the side opposite to the limiting block 501. A limiting groove 507 is formed on the outer side of the connecting tube 506. The limiting shaft 508 is fixedly connected to the inner side of the connecting tube 506. The connecting ring 509 is slidably connected to the inner side of the connecting tube 506. The connecting ring 509 is slidably connected to the limiting shaft 508 and the limiting groove 507. The second spring 510 is sleeved on the outer side of the limiting shaft 508 and fixedly connected to the connecting ring 509. Between the connecting tube 506 and the connecting tube 509, the sleeve 511 is fixedly connected to the outside of the connecting ring 509. The sleeve 511 and the connecting tube 506 are slidably connected. A clamp 512 is fixedly connected to the opposite end of the sleeve 511. The top ends of the connecting tube 506 and the sleeve 511 are provided with insertion holes. The plug 513 can be inserted into the insertion holes at the top ends of the connecting tube 506 and the sleeve 511. The retaining ring 514 is fixedly connected to the opposite end of the connecting tube 506. The roller 6 is fixedly connected to the two ends with retaining shafts 601. The retaining shafts 601 are rotatably connected to the inside of the retaining ring 514. The retaining shafts 601 can be removed from the opening at the top end of the retaining ring 514.

[0052] In practical use, after the heat shrink film storage device is pushed to the location of use by the casters 2, the handle 304 of the grip tube 305 is held to rotate the bidirectional screw 302. Since the threads at both ends of the bidirectional screw 302 are opposite, when the bidirectional screw 302 rotates, it can drive the movable frame 306, which is restricted by the limit rod 301 on both sides of the two ends, to move towards both ends of the bidirectional screw 302, so that the support rod 307 rotates, pushes the support base 308 down and gradually contacts the ground, supports the heat shrink film storage device, and allows the heat shrink film storage device to be placed stably, which facilitates the subsequent storage, retrieval and use of the heat shrink film roll 7.

[0053] When storing the heat shrink film roll 7, the installation height of the roller 6 can be adjusted as needed. Press the button 504 to retract it into the storage groove 502 and disengage it from the positioning hole 402. At this time, the limit block 501 can slide up and down in the guide groove 401. Adjust the limit block 401 as needed so that the button 504 pops out from the corresponding positioning hole 402, thus completing the height adjustment of the limit block 501.

[0054] The heat shrink film roll 7 is fitted onto the outside of the roller 6, and the retaining pins 601 at both ends of the roller 6 are engaged into the retaining rings 514 to complete the installation of the roller 6. The plug 513 is pulled out to unlock the sleeve 511. The second spring 510 pushes the connecting ring 509 to slide inside the connecting tube 506, causing the sleeve 511 to slide and fit onto both ends of the outside of the roller 6. At the same time, the clamping plate 512 holds both ends of the heat shrink film roll 7. The second spring 510 has a built-in damper, which can reduce the reciprocating rebound of the second spring 510, making the clamping plate 512 more stable and allowing the heat shrink film roll 7 to be used stably. The heat shrink film roll 7 will not shake when the heat shrink film storage device is moved.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
