[0020] Please see attached Figure 1-3 A fish-mouth pliers for a steel band type elastic hoop 6 comprises a pliers mouth portion 1, a pliers body 2 and a rotating shaft 3. The two pliers bodies 2 are cross-hinged and arranged on the rotating shaft 3. The pliers bodies 2 are connected to the pliers mouth portion 1. The two pliers mouth portions 1 have a closed state in contact and an open state in separation. The pliers mouth portion 1 is provided with a rack segment 101, a clamping segment 102 and a groove 103. The rack segment 101 is connected to the pliers body 2, and the clamping segment 102 is connected to the rack segment 101. The grooves 103 are respectively arranged on the clamping segments 102 on both sides. The two grooves 103 form a first clamping space 4 in a closed state. The first clamping space 4 is in the shape of a circular hole.

[0021] By adopting the above technical scheme, when using fish-mouth pliers to clamp the steel-strip elastic hoop 6, the pliers body 2 is grasped to make the pliers mouth 1 open, and then the groove 103 of the pliers mouth 1 bites the tail end of the elastic hoop 6. By setting the groove 103, the tail end of the elastic hoop 6 can be better limited, and the bite force of the fish-mouth pliers on the tail end of the steel-strip elastic hoop 6 is improved, so that its use efficiency is improved, the risk of the clamp coming out is reduced, and the operation safety is improved.

[0022] In some embodiments, saw teeth are evenly spaced on the inner wall of the rack segment 101 , and the two rack segments 101 form a second clamping space 5 in a closed state, and the second clamping space 5 is in a water drop shape.

[0023] By adopting the above technical solution, when performing other operations, the friction between the serrations on the rack segment 101 and the object to be clamped is increased to prevent the fish-mouth pliers from detaching from the object to be clamped. Since the two rack segments 101 form a teardrop shape in the closed state, that is, the rack segment 101 is arc-shaped, it can better fit the arc-shaped or circular object to be clamped.

[0024] In some embodiments, an anti-slip cover is provided on the pliers body 2 .

[0025] By adopting the above technical solution and providing an anti-slip cover, workers can grip the fish-mouth pliers more easily when using them.

[0026] In some embodiments, an elastic member is provided between the pliers body 2 , and the elastic member is sleeved on the rotating shaft 3 .

[0027] By adopting the above technical solution, when not in use, the setting of the elastic member can help the two pliers mouth parts 1 to always be in a closed state. When the pliers body 2 is held and force is applied, the pliers mouth part 1 opens to clamp the elastic hoop 6, the elastic member is deformed, and helps the pliers mouth part 1 to clamp the elastic hoop 6.
