[0015] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0016] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0017] Some embodiments of the present utility model provided below will be described with reference to the drawings.

[0018] Referring to Figure 1 、 2 , a multifunctional rope cutter, including a knife handle 1 and a cutter body 2 fixed on the knife handle 1. An installation cavity with an opening on one side is provided inside the knife handle 1. A pair of pliers 3 ejected by a spring is installed in the installation cavity. A slider 4 is provided on the pliers 3. A chute 9 corresponding to the slider 4 is provided on the knife handle 1. The slider 4 is slidably installed in the chute 9. A locking piece 5 reset by a reset spring piece 7 is provided on the outer side of the knife handle 1. The end of the locking piece 5 is clamped on the slider 4. By unlocking the locking piece, the pliers can be ejected, so that in addition to the function of a rope cutter, the function of the pliers is added, and it can be applied to more complex and changeable environments.

[0019] The pliers are provided with a fixed plier handle and a movable plier handle 6. The slider 4 is provided on the fixed plier handle. After installation, the movable plier handle 6 is exposed outside the knife handle 1 through the opening of the installation cavity.

[0020] A cavity is provided inside the fixed pliers handle, and the spring is installed in the cavity, with the other end of the spring abutted against the tool handle 1.

[0021] A pressing column is provided inside the tool handle 1. The pressing column is inserted into the cavity and abutted against the end of the spring.

[0022] The fixed pliers handle and the movable pliers handle 6 are not of a symmetrical structure like conventional pliers. The fixed pliers handle is provided with a straight tube portion, and the cavity is arranged inside the straight tube portion. After the spring is installed, the straight tube portion is aligned with the pressing column for installing the pliers 3. After installation, the spring is always in a compressed state.

[0023] In this embodiment, there are two sliders 4. When the pliers 3 are in the retracted state (as shown in Figure 1 ), one of the sliders 4 is located at one end of the side of the chute 9. When the pliers 3 are in the ejected state (as shown in Figure 2 ), the other slider 4 is located at the other end of the side of the chute 9, which plays a guiding role in retracting and ejecting the pliers 3, and at the same time plays a limiting role to prevent the pliers 3 from directly disengaging from the tool handle 1.

[0024] The locking piece 5 is provided with a bayonet 8 corresponding to the slider 4. The bayonet 8 is clamped on the slider 4. The return spring piece 7 is composed of a fixed part 71 and a spring piece part 72. The spring piece part 72 is fixed on the fixed part 71, and the fixed part 71 is fixed on the outside of the tool handle 1. The spring piece part 72 is always abutted against the side wall of the locking piece 5 and applies a thrust to the locking piece 5. A certain amount of force needs to be applied manually to separate the bayonet 8 from the slider 4 to prevent the locking piece 5 from automatically loosening and causing the pliers 3 to automatically eject.
