After the adjustment, the fixing bolt 6 is screwed into the inside of the adjustment hole 4 to fix the first protective sleeve 2 and the second protective sleeve 3 to prevent the first protective sleeve 2 from accidentally sliding inside the second protective sleeve 3. When the pull-tab body 1 is installed between the aluminum alloy templates, the first protective sleeve 2 and the second protective sleeve 3 can support the aluminum alloy templates.

[0029] Embodiment 2: Two groups of fixing holes 5 are provided, and the fixing holes 5 are symmetrically distributed about the center point of the pull-tab body 1. A fixing pin 7 is provided inside the fixing hole 5, and a slot 8 is provided at the rear end of the fixing pin 7. A latch 9 is provided inside the slot 8. The latch 9 is provided at the rear end of the pull-tab body 1, and the fixing pin 7 is limited by the slot 8 and the latch 9.

[0030] Specifically, as shown in Figures 1 and 1 Figure 2 As shown, when the pull-tab body 1 needs to be fixed, the fixing pin 7 is inserted into the fixing hole 5 and the inside of the aluminum alloy template, and then the latch 9 is clamped in the inside of the slot 8. Clamping the latch 9 in the inside of the slot 8 can not only install and fix the pull-tab body 1, but also prevent the fixing pin 7 from accidentally detaching from the inside of the fixing hole 5, thereby improving the stability of the pull-tab body 1.

The Teflon coating 12 can further improve the anti-corrosion and wear resistance of the surface of the pull-tab body 1. The waterproof layer 13 has a certain waterproof effect, which prevents water from entering the interior of the pull-tab body 1 and causing rust on the surface of the pull-tab body 1, thereby increasing the service life of the pull-tab body 1.

[0033] Working principle: When the utility model is in use, the polyethylene anti-corrosion layer 11 is coated on the outermost layer of the pull-tab body 1, which can make the surface of the pull-tab body 1 have anti-corrosion performance and protect the surface of the pull-tab body 1. The Teflon coating 12 can further improve the anti-corrosion and wear resistance of the surface of the pull-tab body 1. The waterproof layer 13 has a certain waterproof effect, which prevents water from entering the interior of the pull-tab body 1 and causing the surface of the pull-tab body 1 to rust, thereby increasing the service life of the pull-tab body 1. The first protective sleeve 2 and the second protective sleeve 3 are sleeved on the outside of the pull-tab body 1, so as to protect the pull-tab body 1, and then the length of the first protective sleeve 2 exposed outside is adjusted according to the needs of the user. After adjustment, the fixing bolt 6 is screwed into the inside of the adjustment hole 4 to tighten the first protective sleeve 2 and the second protective sleeve 3 are fixed to prevent the first protective sleeve 2 from accidentally sliding inside the second protective sleeve 3. When the pull-tab body 1 is installed between the aluminum alloy templates, the first protective sleeve 2 and the second protective sleeve 3 can support the aluminum alloy template. When the first protective sleeve 2 and the second protective sleeve 3 are not needed, the first protective sleeve 2 and the second protective sleeve 3 can be directly removed from the outside of the pull-tab body 1.
