In this embodiment, the mounting portion 11 is a slot 11 formed on the body 13, a hook (not shown) is disposed on the cpr apparatus and is engaged with the slot 11, a trapezoidal protrusion 111 is formed on a side of the slot 11 close to the side where the cpr apparatus is mounted, and when the hook is engaged with the slot 11, the trapezoidal protrusion 111 is inserted into the hook groove of the hook, so that the hook is engaged with the mounting portion 11 more firmly. Of course, in other embodiments, the mounting portion 11 may be provided with other connecting structures for connecting with the cardiopulmonary resuscitation apparatus, such as a shaft, etc. The pressing device 2 presses the binding band 4 against the body 13. In this embodiment, in order to make the structure of the strap fixing member 10 simpler and the installation more convenient, the base plate 1 is further provided with a slot 12 through which the strap 4 passes. In other embodiments, the bottom plate 1 may not have the slot 12. In this embodiment, the slot 12 is substantially rectangular and is disposed flat on the base plate 1. In other embodiments, the shape of the slot 12 can be other shapes, such as circular, wavy, and the like. The slot 12 has four inner sides, including a first inner side 121 and a second inner side 122 disposed opposite to each other, and a third inner side (not numbered) and a fourth inner side (not numbered) disposed opposite to each other, wherein the first inner side 121 and the second inner side 122 extend along a length direction a1-a2 of the band fastener 10 (the length direction of arrows a1-a2 in fig. 2 is also the length direction of the slot, the length direction of the body 13, and defines that a1 indicates a left side, and a2 indicates a right side).

The pressing device 2 comprises a pressing rod 21 and a connecting rod 22 for connecting the pressing rod 21 and the body 13, and the pressing rod 21 is rotatably connected to the body 13. The two connecting rods 22 are located at two ends of the pressing rod 21, and two ends of the pressing rod 21 are fixed to the connecting rods 22 through fasteners (not numbered). The pressing lever 21 is passed around by the strap 4 and moved toward the base plate 1 under the tension of the strap 4 to press the strap 4 against the base plate 1. The pressing lever 21 is movable relative to the base plate 1 to be configured with an unlocking position (see fig. 4b) and a locking position (see fig. 4 a). In the unlocked position, the strap 4 can move between the pressing bar 21 and the base plate 1; in the locked position, the pressing lever 21 and the base plate 1 press against each other the binding band 4 to fix the binding band 4. In order to increase the friction between the abutment lever 21 and the strap 4, the abutment lever 21 is provided with a toothed structure (not numbered). Specifically, the pressing rod 21 is a roller 21, the binding band 4 is wound around the roller 21, the toothed structure is uniformly laid on the outer surface of the roller 21, and the roller 21 can rotate under the tension of the binding band 4. The directions indicated by arrows c1-c2 in fig. 4a and 4b are height directions, wherein c1 is upward. In the present embodiment, the pressing rod 21 is located in the slot 12 when the pressing rod 21 is at the unlocking position and the locking position, so as to reduce the overall thickness of the strap fixing member 10. Of course, in other embodiments, the abutment lever 21 may be located outside the slot 12 when the abutment lever 21 is in the unlocked position. In the height direction c1-c2 of the band fixing member 10, the first inner side surface 121 is located above the pressing rod 21, and the second inner side surface 122 is located below the pressing rod 21. In this embodiment, the first inner side surface 121 and the pressing rod 21 lock the binding band 4 together. Of course, in other embodiments, the second inner side 122 and the pressing rod 21 can also lock the binding band 4 together. The directions indicated by b1-b2 in fig. 4a are the thickness direction of the bottom plate 1, wherein the direction indicated by the arrow b1 is the rear side and the direction indicated by b2 is the front side). The movable end of the binding band 4 passes through the slot 12 and passes through the pressing rod 21 from front to back, that is, the movable end of the binding band 4 passes through the gap between the pressing rod 2 and the first inner side surface 121 from front to back (see the state of fig. 4 b); the pressing lever 21 moves toward the front side of the base plate 1 under the pulling force of the strap 4, and the position of the pressing lever 21 is changed from the unlocking position of fig. 4b to the locking position of fig. 4a to press the strap 4 against the body 13 (see fig. 4 a). When the binding band 4 needs to be unlocked, only a force towards the direction b1 needs to be applied to the pressing rod 21, so that the position of the pressing rod 21 is moved from the position state of fig. 4a to the position state of fig. 4b, at this time, the gap between the pressing rod 21 and the first inner side surface 121 becomes larger, and the binding band 4 cannot be clamped, so that the binding band 4 can move relative to the pressing rod 21; or, pulling the strap portion behind the strap fixing member 10 in fig. 4a, the strap 4 drives the pressing rod 21 to move toward the b1 direction, and the position of the pressing rod 21 moves from the position state in fig. 4a to the position state in fig. 4b, at this time, the gap between the pressing rod 21 and the first inner side surface 121 becomes larger, and the strap 4 cannot be clamped, so that the strap 4 can move relative to the pressing rod 21.
