[0028] Example

[0029] like Figure 1-6 As shown, the lock cutter of the embodiment includes a body 1, a push rod 2 slidably connected to the body 1, two push rods 2 are arranged on both sides of a lock 3, and the free ends of the two push rods 2 are respectively fixed with a shear knife 4 and a limit block 5; the body 1 is provided with a driving component for driving the two push rods 2 to approach synchronously, and an elastic member for driving the two push rods 2 to move away synchronously is provided between the body 1 and the push rods 2, and the elastic member is clamped between the force-applying end of the push rod 2 and the body 1, and the elastic force direction of the elastic member is parallel to the sliding direction of the push rod 2.

[0030] With such a design, the driving assembly drives the shearing knife 4 and the limit block 5 to cooperate with the shearing lock. When the shearing is completed, the push rod 2 is reset under the action of the elastic member, avoiding the damage of the connecting rod in the prior art and extending the service life of the cutter.

[0031] Specifically, the machine body 1 is provided with a mounting protrusion 11 , a slider 7 is fixedly provided inside the mounting protrusion 11 , and the push rod 2 is slidably connected to the slider 7 .

[0032] Through such a design, the purpose of sliding of the push rod 2 is achieved.

[0033] Furthermore, a limiting protrusion 71 and a slide groove 21 that slidably cooperate with each other are provided between the push rod 2 and the slider 7. The extension direction of the slide groove 21 is parallel to the sliding direction of the push rod 2, and the depth direction of the slide groove 21 is perpendicular to the sliding direction of the push rod 2.

[0034] This design prevents the push rod 2 from rotating during the sliding process.

[0035] Specifically, the driving assembly includes a two-way cylinder 8 and a connecting rod 9. The driving ends of the two connecting rods 9 are respectively rotatably connected to the cylinder body and piston rod of the two-way cylinder 8, the middle section of the connecting rod 9 is rotatably connected to the machine body 1, and the free end of the connecting rod 9 is set to abut against the force-applying end of the push rod 2.

[0036] Through such a design, the shearing knife 4 and the limiting block 5 are brought close to each other.

[0037] Furthermore, the push rod 2 includes a push rod body 22, a ball head 23 and a mounting block 24. The end of the push rod body 22 is provided with an arc groove 221 rotatably connected to the ball head 23. The mounting block 24 is fixedly connected to the push rod body 22. The mounting block 24 is used to limit the connection section of the ball head 23 in the arc groove 221. The ball head 23 is provided with an abutment surface 231 abutting against the free end of the connecting rod 9, and the abutment surface 231 is located outside the mounting block 24.

[0038] With such a design, the cooperation between the ball head 23 and the arc groove 221 ensures that the connecting rod 9 will not interfere with the sliding of the push rod 2 .

[0039] Specifically, the elastic member includes a compression spring 6 , and two ends of the compression spring 6 are respectively disposed against the mounting block 24 and the sliding block 7 .

[0040] Through such a design, the purpose of resetting the push rod 2 is achieved.

[0041] Furthermore, the limiting block 5 is provided with a limiting groove 51 which cooperates with the lock 3 in a limiting manner, and an extending direction of the limiting groove 51 is perpendicular to the sliding direction of the push rod 2 .

[0042] Such a design can limit the position of the lock 3 and prevent the lock 3 from shifting during the cutting process.

[0043] Furthermore, the limiting groove 51 is provided with an abutting protrusion 52 abutting against the lock 3 .

[0044] With such a design, the surface contact between the limiting groove 51 and the lock 3 is changed to a three-point line contact, thereby ensuring that the lock 3 can be deformed and exploded without being protected and blocked by the limiting groove 51 .

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
