Figure 4 , showing Figure 3 The front view of the structure shown below. Figure 1 , Figure 3 and Figure 4 , the structure of the adjustable spacing reflective sheet pasting device of the present invention is explained.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustable spacing reflective sheet pasting device 20 of the present invention includes a housing 21, a mounting shaft 221, a guide shaft 231, a peeling plate 232, a toggle wheel 233, a multi-stage gear 222, a reel 23, an axle 241 and a multi-stage indexing gear 223, an accommodating space 211 is formed inside the housing 21, and an opening 212 is provided at the front of the housing 21; Figure 5 As shown, the mounting shaft 221 is rotatably mounted on the housing 21, and the mounting shaft 221 is used to mount the light-reflecting film roll 10, on which a plurality of light-reflecting films are pasted, and the mounting shaft 221 is located in the accommodating space 211; the guide shaft 231 is arranged near the opening 212, and the guide shaft 231 is passed around by the light-reflecting film roll 10, and the guide shaft 231 is fixedly connected to the housing 21; the peeling plate 232 is arranged on the housing 21 corresponding to the guide shaft 231, and the peeling plate 232 is used to peel off the light-reflecting film on the light-reflecting film roll 10; the toggle wheel 233 is rotatably arranged on the housing 21, and the toggle wheel 233 is used to paste the light-reflecting films from the opening A light-returning film extends out from 212; a multi-stage gear 222 is rotatably mounted on the shell 21 and is located in the accommodating space 211, the multi-stage gear 222 has a plurality of gears 2221 of different sizes, and the multi-stage gear 222 is transmission-connected with the mounting shaft 221; a reel 23 is mounted on the multi-stage gear 222, and the reel 23 is used for winding the light-returning film tape, that is, the blank tape formed after the light-returning film is pasted can be wound on the reel 23; an axle 241 is rotatably mounted on the shell 21, and a walking wheel 242 is fixedly mounted on the end of the axle 241, and the shell 21 can be moved by the arrangement of the walking wheel 242. The multi-stage indexing gear 223 is installed on the wheel shaft 241 and is located in the accommodating space 211. The multi-stage indexing gear 223 has a indexing wheel 2231 that is compatible with the gear. Partial teeth 2232 are provided on the outer periphery of the indexing wheel 2231, and the teeth 2232 on the indexing wheel 2231 can be meshed with the corresponding gear 2221. The spacing between the pasted reflective films can be adjusted by adjusting the corresponding indexing wheel 223 to mesh with the compatible gear 2221.

[0046] On the pasting device 20 of the present invention, the reflective film tape 10 is installed on the mounting shaft 221, and the reflective film tape 10 can rotate with the rotation of the mounting shaft 221. When installing the reflective film tape 10, the end of the reflective film tape 10 is passed around the guide shaft 231 at the opening 212 and then fixed on the reel 23. When pasting the light-returning film, the opening 212 of the shell 21 is placed against the installation surface of the light-returning film, and then the shell 21 is moved by the running wheel 242. When the running wheel 242 rotates, the wheel shaft 241 rotates together, and the wheel shaft 241 rotates with the multi-stage indexing gear 223 thereon. The multi-stage indexing gear 223 drives the installation shaft 221 to rotate through the transmission connection. The rotation of the installation shaft 221 drives the light-returning film tape 10 to rotate, so that when the pasting device 20 moves on the installation surface, the light-returning film tape 10 rotates to release the light-returning film, and the light-returning film at the opening 212 is peeled off by the peeling plate 232, and then extends out of the opening 212, and is then pressed onto the installation surface by the toggle wheel 233. In this way, during the movement of the pasting device 20, the light-returning film is continuously pasted on the installation surface at the opening 212, and the blank light-returning film tape will be wound around the reel 23 and collected, thereby realizing the function of automatically pasting the light-returning film.

[0047] The light-returning sheets on the light-returning sheet roll 10 are arranged closely together, and the light-returning sheets pasted on the mounting surface need to meet certain spacing requirements. When the indexing wheel 2231 on the pasting device 20 of the present invention rotates one circle, only part of the teeth 2232 on it will drive the multi-stage indexing gear 223 to rotate a certain angle. When the teeth 2232 are meshed with the gear 223 again, the multi-stage indexing gear 223 can be driven to rotate, so that the rotation speed of the multi-stage gear 222 is less than the rotation speed of the multi-stage indexing gear 223, so that the interval between the two adjacent light-returning sheets pasted is greater than the interval between the two adjacent light-returning sheets on the light-returning sheet roll. By selecting the size of the indexing wheel and the gear and the number of teeth on the indexing wheel, the interval between the pasted light-returning sheets can be accurately controlled. Since there are multiple indexing wheels of different sizes and gears of different sizes, the pasting device of the present invention has the function of adjusting the interval between the light-returning sheets. By selecting different indexing wheels to mesh with the gears, the corresponding required interval can be adaptively selected.

[0048] In a specific embodiment of the present invention, Figure 1 , Figure 3 and Figure 6 As shown, the pasting device 20 of the present invention also includes a shift handle 25, which is inserted into the shell 21.
