[0030] It should be noted that in this embodiment, when it is necessary to fix the leather, the operator first pulls the loose linkage rod 32 at one end of the side wall sleeve 31. As the loose linkage rod 32 moves, the loose linkage rod 32 drives the limit round block 33 to slide on the inner wall of the side wall sleeve 31,

[0031] wherein, at this time, the height of the limit groove 221 is the same as the diameter of the limit round block 33, and the limit round block 33 is embedded in the inner wall of the limit groove 221 to limit the movement of the entire leather fixing member 20; as the limit round block 33 disengages from the limit groove 221, the limit moving block 22 is unlocked;

[0032] As the limit moving block 22 moves upward, the limit groove 221 on the upward moving side wall of the limit moving block 22 approaches the limit round block 33. Under the action of the return spring 34 on the inner wall of the side wall sleeve 31, the limit round block 33 is embedded in the inner wall of the limit groove 221 to limit the fixed linkage rod 21.

[0033] As Figure 1 , 4 shown, it includes a placement fixed base 10. One end of the side wall sleeve 31 communicates with the inner cavity of the fixed sleeve 11. The side wall of the limit round block 33 is slidably connected to the inner wall of the side wall sleeve 31. The side wall of the limit moving block 22 is slidably connected to the inner wall of the fixed sleeve 11. The other end of the bottom of the placement fixed base 10 is provided with a fixed support leg 12, and the side wall of the fixed sleeve 11 is perpendicular to the side wall of the side wall sleeve 31.

[0034] It should be noted that in this embodiment, the leather fixing member 20 is small in volume, and multiple leather fixing members 20 can be set according to the volume of the processed leather. Among them, the operator fixes the placement fixed base 10 on the processing platform through the fixed support legs 12 at the bottom and bolts, and is arranged at both ends of the head and tail of the leather to be processed, which is convenient for limiting the leather.

[0035] The working principle of the present utility model is:

[0036] In the present utility model, the leather fixing component 20 is small in volume, and a plurality of leather fixing components 20 can be set according to the volume of the processed leather. Among them, the operator fixes the fixing feet 12 at the bottom of the placement fixing base 10 on the processing platform by means of screws and bolts, and arranges them at both ends of the head and tail of the leather to be processed, which is convenient for limiting the leather;

[0037] When the leather needs to be fixed, the operator first pulls the loose linkage rod 32 at one end of the side wall sleeve 31. As the loose linkage rod 32 moves, the loose linkage rod 32 drives the limit round block 33 to slide on the inner wall of the side wall sleeve 31. At this time, the height of the limit groove 221 is the same as the diameter of the limit round block 33, and the limit round block 33 is embedded in the inner wall of the limit groove 221 to limit the movement of the entire leather fixing component 20; as the limit round block 33 disengages from the limit groove 221, the limit moving block 22 is unlocked;

[0038] Subsequently, under the action of the fixing spring 24 on the inner wall of the top of the fixing sleeve 11, the limit moving block 22 is extruded to move downward, and the leather fixing and pressing conical nail feet 23 at the bottom of the limit moving block 22 press and fix the top of the leather. Among them, there are two leather fixing and pressing conical nail feet 23, and the fixed linkage rod 21 can rotate axially to drive the leather fixing and pressing conical nail feet 23 to adjust to the best position to better press the leather;

[0039] After the leather processing is completed, the operator pulls the fixed linkage rod 21 upward. The fixed linkage rod 21 drives the limit moving block 22 to move upward. At the same time, the leather fixing and pressing conical nail feet 23 are lifted upward to release the fixing and pressing of the leather. As the limit moving block 22 moves upward, the limit groove 221 on the upward moving side wall of the limit moving block 22 approaches the limit round block 33. Under the action of the return spring 34 on the inner wall of the side wall sleeve 31, the limit round block 33 is embedded in the inner wall of the limit groove 221 to limit the fixed linkage rod 21. After all the fixing components are released, the operator can easily remove the leather.
