Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2The utility model discloses a portable screw breaking device, comprising a crushing structure 1, wherein a resistance structure 2 and a positioning structure 3 are arranged inside the crushing structure 1, and the crushing structure 1 is movably connected to the resistance structure 2 through the positioning structure 3; the crushing structure 1 comprises an external box 4, wherein a hydraulic cylinder 5 is fixedly installed inside the external box 4, and a crushing cutter head 6 is fixedly connected to the movable end of the hydraulic cylinder 5, and a storage groove 8 is provided inside the external box 4; the resistance structure 2 comprises a movable bracket 9, wherein the end of the movable bracket 9 is located inside the storage groove 8, and a resistance bar 10 is rotatably connected to the inner side of the movable bracket 9; by setting the crushing structure 1 and the resistance structure 2, the movable bracket 9 included in the resistance structure 2 can be moved in the storage groove 8 provided inside the external box 4 included in the crushing structure 1, so that the staff can quickly adjust the distance between the crushing cutter head 6 and the resistance bar 10, so that the volume of the screw breaking device can be self-stored, thereby reducing the volume of the screw breaking device, making the screw breaking device more portable, simple to operate, and improving work efficiency.

[0021] The positioning structure 3 includes a gear 13, which is located inside the storage groove 8 and is rotatably connected to the inner wall of the storage groove 8. The end of the gear 13 away from the inner wall of the storage groove 8 is fixedly connected to a turning handle 14, and the turning handle 14 extends to the outside of the external box 4. The bottom of the gear 13 is meshed with a movable rack 11, and the end of the movable rack 11 is fixedly connected to the end of the movable bracket 9. The inner wall of the storage groove 8 is provided with a damping spring rod 15, and the movable end of the damping spring rod 15 is fixedly connected to a gear ring 16, and the bottom of the gear ring 16 is meshed with the top of the gear 13, and the top of the damping spring rod 15 extends to the top of the external box 4.

[0022] By utilizing the automatic resilience of the damping spring rod 15 , the damping spring rod 15 can drive the gear ring 16 to automatically mesh with the top end of the gear 13 , thereby preventing the gear 13 from rotating on its own.

[0023] Specifically, a placement recess is provided at the top of the external box 4, and a rotating handle 7 is hinged inside the placement recess.

[0024] In this embodiment, the use of the rotating handle 7 can facilitate the staff to hold the external box 4 through the rotating handle 7.

[0025] Specifically, a conflict notch is provided on one side of the conflict strip 10 close to the crushing blade head 6, and the conflict notch is a triangular notch.

[0026] In this embodiment, the interference notch can be used to select a notch or plane on the surface of the interference strip 10 to correspond to the side surface of the screw top.

[0027] Specifically, the bottom end of the movable rack 11 is fixedly connected to a limit pin 12 , and the limit pin 12 is slidably connected to the inner wall of the storage slot 8 .

[0028] In this embodiment, the limiting pin 12 is used to follow the moving rack 11 to slide along the inner wall of the receiving groove 8, thereby improving the movement stability of the moving rack 11.

[0029] When in use, first measure the size of the screw to be crushed, and adjust the distance between the crushing blade 6 and the abutment bar 10 according to the size, so that the staff pulls up the damping spring rod 15 in advance, prompting the damping spring rod 15 to drive the gear ring 16 to separate from the surface of the gear 13, so that the gear 13 can rotate at this time, and then turn the handle 14, so that the handle 14 drives the gear 13 to rotate, and the rotation of the gear 13 drives the moving rack 11 to move, so that the moving rack 11 drives the moving bracket 9 to slide along the direction of the storage slot 8, prompting the moving bracket 9 to drive the abutment bar 10 to gradually move away from the external box 4;

[0030] Next, the notch or plane on the surface of the abutment strip 10 is selected to correspond to the side surface of the screw top, and then the hydraulic cylinder 5 is started so that the movable end of the hydraulic cylinder 5 drives the crushing cutter head 6 to move toward the abutment strip 10, causing the screw top to be crushed.

[0031] To sum up, the portable screw breaking device, by setting a crushing structure 1 and a resistance structure 2, utilizes the movable bracket 9 included in the resistance structure 2 to move within the storage groove 8 opened inside the external box 4 included in the crushing structure 1, so that the staff can quickly adjust the distance between the crushing blade head 6 and the resistance bar 10, so that the volume of the screw breaking device can be self-stored, thereby reducing the volume of the screw breaking device, making the screw breaking device more portable and simple to operate, and improving work efficiency.
