[0030] A suspension rod 3 is fixedly installed on the side of the support frame 2. The suspension rod 3 is used to suspend the blade replacement unit 1, so that the blade replacement unit 1 can be stored after use, making it convenient for operators to use.

[0031] Furthermore, a blade groove 206 is provided on the side of the second stage 203 near the first stage 202; two bearing seats 208 are installed on the support frame 2, and a rotating shaft 209 is rotatably connected between the two bearing seats 208 through a bearing. The outer surface of the rotating shaft 209 is provided with a blade body 212, and the top of the blade body 212 extends out from the blade groove 206. The bearing seats 208 can support the rotating shaft 209.

[0032] Furthermore, a tool holder 210 is fixedly sleeved on the outer surface of the rotating shaft 209. Several insertion rods 211 are fixedly installed on the side of the tool holder 210 near the blade body 212. Several insertion holes 213 are opened on the blade body 212. The inner wall of the insertion hole 213 is connected to the outer surface of the insertion rod 211. The insertion hole 213 and the insertion rod 211 cooperate with each other to restrict the blade body 212, so that the blade body 212 rotates with the rotating shaft 209.

[0033] Furthermore, the outer surface of the rotating shaft 209 near the blade body 212 is provided with threads, and a fixing nut 214 is threadedly connected to the rotating shaft 209.

A through hole 403 is provided on the rotating shaft 209, and the position of the through hole 403 corresponds to the position of the first hand-tightening bolt 402. Before tightening the fixing nut 214, the first hand-tightening bolt 402 is inserted into the through hole 403 to limit the rotation of the rotating shaft 209, so as to prevent the rotating shaft 209 from rotating, thereby facilitating the rotation of the fixing nut 214.

[0037] Furthermore, a limiting part 5 is provided on the first platform 202. The limiting part 5 includes a stop bar 501 slidably connected to the top of the first platform 202. A fixing plate 503 is connected to the side of the stop bar 501 away from the blade body 212. An elongated opening 505 is provided on the fixing plate 503. A second hand-tightening bolt 504 is provided on the fixing plate 503. A plurality of threaded holes 502 are provided on the first platform 202. The bottom end of the second hand-tightening bolt 504 passes through the elongated opening 505 and is threadedly connected to one of the threaded holes 502. The length of the meat cut can be confirmed by the stop bar 501. The position of the stop bar 501 can be adjusted by unscrewing the second hand-tightening bolt 504.

[0038] The length of the elongated opening 505 is the distance between the two threaded holes 502. The elongated opening 505 compensates for the distance difference between the threaded holes 502, thereby increasing the range of position adjustment of the stop bar 501.

[0039] The blade replacement mechanism and cutting table provided by this utility model are used as follows:

[0040] Unscrew the second hand-tightening bolt 504, then push the stop bar 501 to move. Adjust the position of the stop bar 501 according to the actual situation. Then, pass the second hand-tightening bolt 504 through the threaded hole 502 and connect it with the corresponding threaded hole 502. Place the meat to be cut on the second platform 203 and the first platform 202. The meat contacts the stop bar 501 to confirm the length. The operator holds the handle 101 and fixes the meat with the pusher 104 and moves it towards the blade body 212 to cut through the blade body 212.

[0041] When replacing the blade body 212, unfasten the latch 205 and pull the second platform 203 upward to separate the limiting rod 204 from the support frame 2, then remove the second platform 203, insert the first hand-tightening bolt 402 into the through hole 403, put the slot 103 into the fixing nut 214 and tighten it to remove the fixing nut 214, then pull the blade body 212 to remove the old blade body 212, put the new blade body 212 into the rotating shaft 209, and insert the insertion hole 213 into the insertion rod 211, then tighten the fixing nut 214 into the rotating shaft 209, rotate the first hand-tightening bolt 402 to separate the first hand-tightening bolt 402 from the through hole 403, insert the limiting rod 204 into the support frame 2, and then use the latch 205 to fix it.
