The structure is convenient for users to quickly disassemble and assemble the installation component 5 and the extension connection component 3 by setting the clamping column 52 and the extension rod 31 into a clamping structure, and the outer surface of the clamping column 52 is annularly equidistantly installed with an elastic limiting mechanism 53, and the end of the elastic limiting mechanism 53 is fixedly connected to a connecting plate 54, and the other end of the connecting plate 54 is fixedly installed with an arc-shaped clamping block 55, and a magnetic stone 56 is embedded on the top of the load-bearing plate 51, and the bottom outer surface of the installation component 5 is annularly equidistantly fixedly connected with a fixing rod 6, and an annular film-breaking plate 7 is fixedly installed at the bottom of the fixing rod 6, and an arc-shaped punching knife 8 is welded to the bottom of the annular film-breaking plate 7 in annular shape and equidistant.

[0024] like Figure 1 and Figure 2As shown, a grip rod 2 is fixedly installed on the top of the connecting sleeve 1, and an extension connection component 3 is movably installed on the inner surface of the bottom of the connecting sleeve 1, and the extension connection component 3 includes an extension rod 31, a slot 32, an annular limiting plate 33, a limiting groove 34, an annular auxiliary disassembly sleeve 35 and an arc-shaped slider 36, and the outer surface of the extension rod 31 is provided with slots 32 at equal distances, and an annular limiting plate 33 is fixedly installed on the outer surface of the extension rod 31, and a limiting groove 34 is provided at the bottom of the extension rod 31, and an annular auxiliary disassembly sleeve 35 is movably installed on the outer surface of the extension rod 31, and the inner surface of the annular auxiliary disassembly sleeve 35 is annularly and equidistantly fixedly connected with an arc-shaped slider 36, the inner surface of the annular auxiliary disassembly sleeve 35 is fixedly connected with the outer surface of the arc-shaped slider 36, and the annular auxiliary disassembly sleeve 35 forms a sliding structure with the extension rod 31 through the arc-shaped slider 36, and the annular auxiliary disassembly sleeve 35 and the extension rod 31 are set as a sliding structure, so that the annular auxiliary disassembly sleeve 35 is lifted and moved along the outer surface of the extension rod 31 The invention relates to a method for making the locking mechanism 4 of the extension sleeve 1 more smooth and stable. The locking mechanism 4 is installed on the outer side of the connecting sleeve 1, and the locking mechanism 4 includes a locking rod 41, a pull plate 42 and a return spring 43. The end of the locking rod 41 is fixedly connected to the pull plate 42. The outer size of the end of the locking rod 41 is completely consistent with the inner size of the card slot 32. The locking rod 41 forms a card-engaging structure with the extension rod 31 through the card slot 32.

[0025] In summary, the combined assembled film breaking knife is first based on Figures 1 to 4, the user grasps the carrying plate 51 and inserts the clamping column 52 into the inner surface of the end of the extension rod 31 through the cooperation of the limiting groove 34. At this time, as the extension rod 31 is squeezed, the arc-shaped clamping block 55 drives the connecting plate 54 to move toward the inside of the clamping column 52. When the clamping column 52 is completely immersed in the end of the extension rod 31, the connecting plate 54 drives the arc-shaped clamping block 55 to be clamped into the inside of the limiting groove 34 through the rebound force of the elastic limiting mechanism 53, thereby completing the self-locking function, so that the user can quickly assemble the film breaking knife. Then the user grasps the pulling plate 42 and pulls it outwards, The locking rod 41 is moved out from the inside of the slot 32, and then the user grabs the extension rod 31 and pulls it out from the inside of the connecting sleeve 1. When the height of the film breaking knife reaches the required height of the user, the user releases the pull plate 42, so that the pull plate 42 drives the locking rod 41 to be inserted into the slot 32 through the rebound force of the reset spring 43, thereby achieving the purpose of locking the extension rod 31. Then the user grabs the gripping rod 2 and drives the connecting sleeve 1 to press down toward the required film breaking point through it, and then the annular film breaking plate 7 drives the arc-shaped punching knife 8 to automatically break the ground film through the cooperation of the fixing rod 6.
