[0036] like Figures 1 to 7As shown, an embodiment of this utility model provides a fixing device for leather processing, including an upper fixing frame 1 and a lower fixing frame 2 that are interlocked. The upper fixing frame 1 includes a pair of upper fixing rods 4 and upper connecting rods 5, which are connected to each other to form a square frame. Adjacent upper fixing rods 4 and upper connecting rods 5 are connected by a locking mechanism 3. The lower fixing frame 2 includes a pair of lower fixing rods 6 and lower connecting rods 7, which are connected to each other to form a square frame. Adjacent lower fixing rods 6 and lower connecting rods 7 are connected by a locking mechanism 3. The upper fixing rods 4 and lower fixing rods 5 are interlocked to form a square frame. The upper connecting rod 5 and the lower connecting rod 7 have the same structure. In use, the paired upper fixing rod 4 and upper connecting rod 5 are combined to form the upper fixing frame 1, and the paired lower fixing rod 6 and lower connecting rod 7 are combined to form the lower fixing frame 2. The upper fixing rod 4 in the upper fixing frame 1 and the lower fixing rod 6 in the lower fixing frame 2 are positioned correspondingly, and the upper connecting rod 5 in the upper fixing frame 1 and the lower connecting rod 7 in the lower fixing frame 2 are positioned correspondingly. The fixing buckle 19 on the upper fixing rod 4 is embedded in the locking hole 13 on the lower connecting rod 7, so that the four corners of the upper fixing frame 1 and the lower fixing frame 2 are fixed to each other, achieving the purpose of quick fixing.

[0037] like Figures 3 to 6 As shown, the upper connecting rod 5 includes a center plate 11, with extension rods 12 fixedly connected to both ends of the center plate 11. The extension rods 12 are perpendicular to each other. A locking hole 13 is provided at the top of the center plate 11. The locking hole 13 is a slanted groove structure and passes through the upper connecting rod 5. A center groove 15 is provided in the middle of the outer wall of the center plate 11. Wiring grooves 14 are provided on both sides of the center groove 15 and extend to the side wall of the corresponding extension rod 12. The upper fixing rod 4 is a right-angle rod with a chamfer at the corner. Adjustment grooves 16 are provided at both ends of the upper fixing rod 4. The structure of the adjustment grooves 16 is adapted to the extension rods 12. Several sets of locking grooves 17 are provided at the bottom of the adjustment grooves 16. A fixing buckle 19 is provided at the chamfer at the bottom of the upper fixing rod 4. The fixing buckle 19 is a hook-shaped structure and is fixedly connected to the extension rod 12. The upper fixing rod 4 has an angle greater than 90° between its upper surface and bottom surface. A pressure plate 18 is fixedly connected to the inner wall of the upper fixing rod 4. The pressure plate 18 has a bent cross-section with its tip pointing downwards. A fixing buckle 19 is set, and the tilt angle of the fixing buckle 19 is the same as the tilt angle of the locking hole 13. When fixing the upper fixing frame 1 and the lower fixing frame 2, one end of the fixing buckle 19 needs to be inserted into the locking hole 13 first. Then, the upper fixing frame 1 is rotated relative to the lower fixing frame 2 by a certain angle so that the fixing buckle 19 is fully inserted into the locking hole 13 and the edge of the fixing buckle 19 is locked. The cooperation between the fixing buckle 19 and the locking hole 13 makes the upper fixing frame 1 and the lower fixing frame 2 constrained in both the longitudinal and transverse directions, thereby achieving the purpose of fixing the upper fixing frame 1 and the lower fixing frame 2.

[0038] like Figure 3 and Figure 7As shown, the locking mechanism 3 includes an adjusting knob 8 installed in the central groove 15 and rotatably connected to the central plate 11. The locking mechanism 3 also includes a locking block 10 installed on the outer end of the extension rod 12. The adjusting knob 8 and the locking block 10 are connected by a connecting line 9. A pair of first fixing rings 20 are symmetrically fixed to the side wall of the rotating shaft of the adjusting knob 8. The locking block 10 is a pawl structure with one sharp end. One end of the locking block 10 is provided with a connecting hole 22 and is rotatably connected to the extension rod 12 through the connecting hole 22. The other end of the locking block 10 is fixedly connected to a second fixing ring 21 for connecting to the connecting line 9. When the upper fixing rod 4 is combined with the upper connecting rod 5 or the lower fixing rod 6 is combined with the lower connecting rod 7, rotating the adjusting knob 8 drives the connecting line 9 to pull the tip of the locking block 10 upward, so that the tip of the locking block 10 reaches... The adjustment knob 8 is flush with the bottom surface of the extension rod 12 to facilitate the extension rod 12 entering the adjustment groove 16. After the extension rod 12 enters the appropriate position in the adjustment groove 16, the adjustment knob 8 is released, so that the traction force of the connecting line 9 on the locking block 10 disappears. The tip of the locking block 10 moves down under the action of gravity and is embedded in the corresponding locking groove 17, thereby restricting the movement of the extension rod 12 in the adjustment groove 16 and realizing the fixation between the upper fixed rod 4 and the connected upper connecting rod 5. The connection method between the lower fixed rod 6 and the lower connecting rod 7 is the same as the connection method between the upper fixed rod 4 and the upper connecting rod 5. When it is necessary to adjust the size of the upper fixed frame 1, the adjustment knob 8 is rotated to drive the tip of the locking block 10 to move up through the connecting line 9, thereby releasing the locking state between the upper fixed rod 4 and the upper connecting rod 5 or the lower fixed rod 6 and the lower connecting rod 7.

[0039] The working principle provided by this utility model is as follows: During installation, the pairs of rods are first arranged into a square frame structure, with each upper fixed rod 4 having an upper connecting rod 5 adjacent to it. The adjustment knob 8 on the center plate 11 is rotated, and the adjustment knob 8 drives the locking block 10 installed at the end of the extension rod 12 to rotate through the two connecting lines 9 connected to it, so that the tip of the locking block 10 moves upward. Then, the extension rod 12 is inserted into the adjustment groove 16 on the adjacent upper connecting rod 5, and the positions of the upper fixed rod 4 and the upper connecting rod 5 are adjusted appropriately. After the adjustment knob 8 is released, the locking block 10 falls naturally and embeds into the corresponding locking groove 17 to lock the adjacent upper fixed rod 4 and upper connecting rod 5.

[0040] After assembling and fixing the lower fixing rod 6 and the lower connecting rod 7 in the same way, overlap the assembled upper fixing frame 1 and lower fixing frame 2, aligning the upper fixing rod 4 with the lower fixing rod 6, the upper connecting rod 5 with the lower fixing rod 6, and the fixing buckle 19 with the locking hole 13. Rotate the upper fixing frame 1 and the lower fixing frame 2 so that the fixing buckle 19 is fully inserted into the locking hole 13 and latches its edge, thus completing the fixing between the upper fixing frame 1 and the lower fixing frame 2. Before fixing the upper fixing frame 1 and the lower fixing frame 2, a leather pad can be inserted into the gap between the upper fixing frame 1 and the lower fixing frame 2. After the upper fixing frame 1 and the lower fixing frame 2 are fixed, the leather pad is clamped, thereby achieving the purpose of fixing the leather pad.

[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.
