As shown in fig. 5 and 7, magnetic jaw 242 may include a chute base 2421 and a second jaw 2423 extending and projecting obliquely upward from chute base 2421. One end of the sliding groove seat 2421 corresponding to the second clamping jaw 2423 is used as a first clamping jaw (hereinafter, the reference numeral of the first clamping jaw is referred to as 2421), and the sliding groove seat 2421 is provided with a through groove 2422 for sleeving the connecting block 241, so that the magnetic clamping jaw 242 can slide relative to the connecting block 241. Furthermore, the magnetic jaw 242 is provided with a pivot hole 2424 for connecting with the movable jaw 243, and is further provided with a slot 2425 corresponding to the groove 2413 of the connecting block, so that the movable jaw 243 can extend into. The first jaw 2421 and the second jaw 2423 of the magnetic jaw 242 may be made of a magnetic material, such as a permanent magnetic ferromagnetic material, or may be provided with corresponding ferromagnetic members at the positions thereof.

As shown in fig. 5 and 8, the movable jaw 243 is made of a material that can be attracted to the first jaw 2421 and the second jaw 2423 of the magnetic jaw. The movable clamping jaw 243 is also pivotally connected to the magnetic clamping jaw 242, one end of the movable clamping jaw has a bending portion 2431 extending into the groove 2413 of the connecting block, and the other end 2432 of the movable clamping jaw can be attracted to the first clamping jaw 2421 and the second clamping jaw 2423 of the magnetic clamping jaw. The movable jaw 243 is disposed between the first jaw 2421 and the second jaw 2423 of the magnetic jaws and is engaged with one of the jaws. The movable jaw 243 is pivotally connected to the magnetic jaw 242 by its pivot holes 2433. The end of the bending part 2431 of the movable clamping jaw is correspondingly of a cambered surface structure.

When the magnetic clamping jaw 242 and the connecting block 241 slide relatively, the movable clamping jaw 243 can slide together with the magnetic clamping jaw 242 relative to the connecting block 241, and the bent part 2431 of the movable clamping jaw is in contact with one end of the connecting block groove 2413, so that the movable clamping jaw 243 rotates around a pivot and is released from the clamping jaw which is engaged with the movable clamping jaw before and is engaged with the other clamping jaw to clamp or release the tourniquet.

In the above embodiment, referring to fig. 5, it can be seen that when the conveyor belt stops rotating, the connecting block 241 is also kept fixed, and the magnetic clamping jaw 242 and the movable clamping jaw 243 can continuously slide a short distance due to inertia. For example, as the magnetic jaw 242 and the movable jaw 243 slide relatively downward in FIG. 5, the movable jaw 243 may change from engagement with the second jaw 2423 to engagement with the first jaw 2421.

For example, when the movable clamping jaw 243 is attracted to the first clamping jaw 2421 of the magnetic clamping jaw, the tourniquet can be clamped; when the movable clamping jaw 243 is attracted with the second clamping jaw 2423 of the magnetic clamping jaw, the tourniquet can be released. With reference to the drawings, it can be seen that when the magnetic jaw 242 and the movable jaw 243 slide relative to each other on the connecting block towards the connecting portion 241 protruding from the connecting block, the movable jaw 243 is shifted to be engaged with the first jaw 2421, and vice versa, the movable jaw 2423 is engaged.
