[0013] (3) Beneficial effects

[0014] Compared with the prior art, the utility model provides a winding film bracket, which has the following beneficial effects:

[0015] For this winding film bracket, by setting an adjusting mechanism, a lifting mechanism and a positioning mechanism, first, the positioning mechanisms on both sides are adjusted to move away from each other through the adjusting mechanism. Pull the pull ring to drive the baffle and the wedge block to move forward. The movement of the wedge block pushes the wedge plates on both sides to move away from each other. While pushing the push plate to move, the spring is compressed. The push plate can drive the base, the first positioning roller, the vertical rod, the second positioning roller and the top seat to move accordingly. After adjusting the position of the positioning mechanism, pull out the winding film through between the first positioning rollers and the second positioning rollers on both sides, and then release the pull ring. Under the tension of the spring, the push plate is reset. In this way, the positioning mechanism limits the end of the winding film to prevent it from wrinkling. Secondly, the positioning mechanism can be adjusted through the lifting mechanism to adapt to winding films of different sizes. The handle can be used to pull the box body up and down. During the movement, the convex block slowly disengages from the groove and pushes the movable plate and the connection to move and compress the fixed spring. Supported by the fixed plate, the connecting rod moves more stably. When the convex block no longer fits with the groove, the box body can be moved up and down, so as to adjust the second positioning roller to slide outside the vertical rod. Changing the distance between the second positioning roller and the first positioning roller can be applicable to winding films of different sizes. After adjusting to an appropriate height, the tension of the fixed spring pushes the movable plate and the convex block to reset. When the convex block extends into the inner side of the groove again, the clamping is completed, and the position of the installation box is fixed, thus achieving the purpose of easy adjustment.

[0033] In summary, for this winding film bracket, by setting the adjusting mechanism 4, the lifting mechanism 5 and the positioning mechanism 6, first, the adjusting mechanism 4 is used to adjust the two-sided positioning mechanism 6 to move away from each other. Pull the pull ring 48 to drive the baffle 46 and the wedge block 45 to move forward. The movement of the wedge block 45 pushes the two-sided wedge plates 44 to move away from each other. While pushing the push plate 42 to move, the spring 43 is compressed. The push plate 42 can drive the base 61, the first positioning roller 62, the vertical rod 65, the second positioning roller 64 and the top seat 63 to move accordingly. After adjusting the position of the positioning mechanism 6, pull out the winding film through between the two-sided first positioning rollers 62 and the second positioning rollers 64, and then release the pull ring 48. Under the tension of the spring 43, the push plate 42 is reset. In this way, the positioning mechanism 6 limits the end of the winding film to prevent it from wrinkling. Secondly, the lifting mechanism 5 can be used to adjust the positioning mechanism 6 to adapt to winding films of different sizes. By pulling the handle 59, the box body 52 can be moved up and down. During the movement, the convex block 57 slowly disengages from the groove 53 and pushes the movable plate 56 and the connecting rod 55 to move and compress the fixed spring 58. Supported by the fixing plate 54, the connecting rod 55 moves more stably. When the convex block 57 no longer fits with the groove 53, the box body 52 can be moved up and down, so as to adjust the second positioning roller 64 to slide outside the vertical rod 65, and change the distance between the second positioning roller 64 and the first positioning roller 62 to be applicable to winding films of different sizes. After adjusting to an appropriate height, the tension of the fixed spring 58 pushes the movable plate 56 and the convex block 57 to reset. When the convex block 57 extends into the inner side of the groove 53 again, the clamping is completed and the position of the installation box 41 is fixed, thus achieving the purpose of easy adjustment, solving the problems that there is no certain positioning structure, the end of the winding film is prone to wrinkling when the winding film is pulled out, affecting the use effect, and it cannot be adjusted to be applicable to winding films of different sizes, reducing the practicability of the bracket.
