A pin hole adapted to the third pin 1-12 is provided at a position slightly below the middle of the pressure rod 1-3;

[0031] A pin hole adapted to the second pin is provided at the lower end of the pressure rod 1-3, and the upper end of the pressure rod 1-3 is the manual operation end;

[0032] A mounting hole for installing a strap screw 1-13 is provided on the bottom plate 1-8, and a mounting hole for installing another strap screw 1-13 is provided at a position slightly above the middle of the pressure rod 1-3. Both ends of the tension spring 1-7 are respectively hung on the two strap screws 1-13.

[0033] The leather knife sheath assembly inner lining jig 1 is composed of multiple components, and its assembly process is as follows:

[0034] Step 1: Install the positioning rod 1-6 into the placement hole of the second fixed plate 1-5;

[0035] Step 2: Install the second fixed plate 1-5 and the first fixed plate 1-4 into the two mounting grooves of the bottom plate 1-8, and lock multiple hexagon socket head cap screws 1-9.

[0036] Step 3: Assemble the ejector rod 1-1, the drive rod 1-2 and the copper sleeve 1-10 and then place them between the second fixed plate 1-5 and the first fixed plate 1-4, and insert the first pin 1-11.

[0037] Step 4: Install the pressure rod 1-3 between the second fixed plate 1-5 and the first fixed plate 1-4, insert the second pin, and assemble the pressure rod 1-3 and the drive rod 1-2 and insert the third pin 1-12.

The pressure rod 1-3 rotates to drive the driving rod 1-2 to rotate. The driving rod 1-2 rotates to push the first pin 1-11 to slide horizontally in the first chute and the second chute. The first pin 1-11 pushes the ejector rod 1-1 to slide horizontally. One end of the ejector rod 1-1 is the pressing end of the inner lining of the leather knife sheath. Finally, the inner lining is pushed into the leather sheath, causing the leather sheath to stretch and expand to achieve the assembly purpose. During this assembly process, the tension spring 1-7 elongates. When the assembly is completed, manually release the pressure on the pressure rod 1-3, and the tension spring 1-7 returns, driving each part of the jig to return to its original state.

[0040] Compared with the prior art, the positive effect of the present utility model is as follows: The jig for assembling the inner lining of the leather knife sheath in the present utility model hangs the leather knife sheath with the pre-installed inner lining on the positioning rod, and uses the driving rod to push the pressure rod to drive the ejector rod to hard-press the inner lining into the leather sheath, causing the leather sheath to stretch and expand to achieve the assembly purpose. The above jig realizes the labor-saving and convenient assembly of the inner lining of the leather knife sheath, improves the production efficiency and reduces the labor intensity, and solves the problem that in the existing actual production, operators use simple tools for manual assembly, which is laborious and inefficient during the assembly process.

[0041] In summary, only the preferred technical solutions of the present utility model are reflected.
