A mounting base 3 is slidably provided at one end of the slide rod 2. Springs 4 are provided around the slide rod 2. One end of the springs 4 is fixedly connected to the mounting base 3. A slide rail 5 is fixedly provided on the inner wall of the mounting base 3. The slide rail 5 is T-shaped.

[0024] In this embodiment, there are four slide rails 5 in total, two in a group. There are two slide rails 5 on the mounting base 3. A clamping block 6 is slidably installed inside the mounting base 3. Mounting brackets 7 are fixedly installed on both sides of the slide rod 2 away from the mounting base 3. There are two mounting brackets 7 in total. The upper mounting bracket 7 is longer than the lower mounting bracket 7. The lower mounting bracket 7 is fixedly connected to the housing 1, and the upper mounting bracket 7 is slidably connected to the housing 1.

[0025] In this embodiment, the mounting bracket 7 is located at one end inside the housing 1, and an internal threaded tube 8 and a screw 9 are provided on the opposite side. The screw 9 is fixedly connected to the mounting bracket 7, and the internal threaded tube 8 is rotatably connected to the mounting bracket 7. The screw 9 and the internal threaded tube 8 are meshed together. A toothed ring 10 is fixedly provided at the lower end of the mounting base 3. A pressure roller 11 is provided on one side of the toothed ring 10, and a rotating shaft 12 is fixedly provided on the side of the pressure roller 11 near the housing 1.

[0026] In this embodiment, the other end of the rotating shaft 12 is rotatably connected to the housing 1. The outer surface of the rotating shaft 12 is provided with a toothed groove. The toothed ring 10 meshes with the toothed groove on the rotating shaft 12. The clamping block 6 is provided with a sliding groove 13 on the side near the slide rail 5. The sliding groove 13 is slidably connected to the slide rail 5. A friction block 14 is provided on one side of the sliding groove 13.

[0027] In this embodiment, one side of the friction block 14 is in contact with the slide rail 5, and a connecting rod 15 is rotatably provided on the side of the friction block 14 away from the slide rail 5. Two connecting rods 15 are symmetrically arranged along the center line of the friction block 14.

[0028] In this embodiment, a bracket 16 is provided at the other end of the connecting rod 15, and the connecting rod 15 is slidably connected to the bracket 16. A second spring 17 is fixedly provided in the middle of the friction block 14, and the other end of the second spring 17 is fixedly connected to the clamping block 6.

[0029] Working principle: During the feeding operation, the worker first places the raw material in the clamping block 6 and then slowly pushes it towards the pressure roller 11. During this process, the clamping block 6 acts as the first line of defense. If the worker's hand is not removed in time and is pulled forward by the pressure roller 11, the clamping block 6 will first stop the hand from moving forward, effectively preventing the hand from being directly caught in the core operating area. If the worker's hand is still not out of danger after the clamping block 6 intervenes, the mounting base 3 will gradually slide towards the pressure roller 11 as the situation develops until the gear ring 10 engages with the rotating shaft 12. At this point, the gear ring 10 can lock the rotating shaft 12, preventing the pressure roller 11 from rotating further and forcing the device to stop. After the pressure roller 11 stops rotating, other workers can cut off the power to the device and directly push the raw material along with the clamping block 6 out of the mounting base 3. When the clamping block 6 is pushed out, it can be directly removed from the worker's hand, which can reduce the difficulty of rescuing the worker.

[0030] The slot on the clamping block 6 allows it to adapt to the shape of the raw material being processed. When processing raw materials of different shapes, it is only necessary to replace the clamping block 6 with one of different specifications. When replacing the clamping block 6, it can be directly removed. When the new clamping block 6 is installed into the mounting base 3, the friction block 14 inside is pushed towards the slide rail 5 under the action of the spring 17, fixing the clamping block 6. The clamping block 6 is also fixed by friction, which can ensure normal processing and convenience when rescuing injured workers. Furthermore, the spacing of the mounting base 3 can be adjusted by adjusting the tightness of the internal threaded tube 8 and the screw 9, which can accommodate more raw materials of different specifications.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
