[0025] The utility model discloses a hand-pull film coating device, which mainly comprises a cross bar 1, an L-shaped force arm 2, an adjusting screw 3, a conical tube 4, a pull rod 5, a sleeve 6, a telescopic sleeve 7, a limit pin 8, and a pressure block 9. The cross bar 1 is a hollow structure, and internal threaded holes are arranged at both ends of the cross bar 1. One end of the L-shaped force arm 2 can be telescopically sleeved on the end of the cross bar 1. The L-shaped force arm 2 is connected to the internal threaded hole at the end of the cross bar 1 through the adjusting screw 3. The conical tube 4 is installed on the inner side of the bottom end of the L-shaped force arm 2. The spacing between the conical tubes 4 can be changed by adjusting the adjusting screw 3, which is convenient for clamping the film roller; the bottom end of the pull rod 5 is fixedly installed on the cross bar 1 The sleeve 6 is installed on the pull rod 5, and the film roller can be easily pulled through the pull rod 5 for easy film coating; the telescopic sleeve rod 7 can be slidably inserted into the sleeve 6, and the sleeve 6 and the telescopic sleeve rod 7 are limited and fixed by the limit pin 8, and a pressure block 9 for fixing the film roller is fixed at the bottom of the telescopic sleeve rod 7; operating the telescopic sleeve rod 7 can make the pressure block 9 break away from the contact with the film roller, and the film roller can be easily pulled through the pull rod 5 for easy film coating. After the ground film is pulled open, the telescopic sleeve rod 7 is operated to press the pressure block 9 on the film roller to prevent the film roller from rotating. The pull rod 5 can be pulled to tighten the ground film to ensure that the ground film is flat after covering the soil and the quality of film coating is guaranteed. The operation is simple and convenient, which is conducive to improving work efficiency and reducing labor intensity.

[0026] The telescopic sleeve 7 comprises a sleeve 71, a compression spring 72 and a pressure rod 73. The compression spring 72 is arranged in the sleeve 71. A slider 74 is provided at the front end of the pressure rod 73. The front end of the pressure rod 73 can be slidably installed in the sleeve 71 through the slider 74. A hole shoulder is provided at the top end of the sleeve 71 for limiting the stroke of the slider 74. The pressure rod 73 can be slidably passed through the sleeve 6. The retracted height of the sleeve 71 is guaranteed by the limitation of the hole shoulder and the slider 74 to avoid the pressure block 9 from rubbing against the film roller when the ground film is pulled open. The compression spring 72 can ensure that when the film roller is pressed, the sleeve 71 has a certain amount of elastic compression to match the compression after the size of the film roller changes with the use of the ground film, thereby increasing the scope of application and improving practicality.

[0027] The two ends of the compression spring 72 are limited by the bottom end of the inner hole of the sleeve 71 and the slider 74 respectively. The compression spring 72 is in a compressed state to ensure the mutual pressure between the sleeve 71 and the pressure rod 73 when the pressure rod 73 is in a high position, thereby preventing the sleeve 71 from shaking.
