Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0040] refer to Figures 1 to 6 ,like Figure 1As shown, this embodiment provides a shoe last clamping device, including: a base 1, a pair of first clamping mechanisms 2 and a pair of second clamping mechanisms 3, the pair of first clamping mechanisms 2 are symmetrically installed at the left and right ends of the base 1; the pair of second clamping mechanisms 3 are symmetrically installed at the front and rear ends of the base 1; the first clamping mechanism 2 includes a side plate 21 and a clamping assembly, the lower part of the side plate 21 is slidably matched with the base 1, and the side plate 21 can be fixed at different positions of the base 1 to adjust the position of the side plate 21, the clamping assembly is installed on the side plate 21, and the clamping assembly can clamp the top of the shoe last; the second clamping mechanism 3 can clamp the front and rear ends of the shoe last, therefore, the first clamping mechanism 2 and the second clamping mechanism 3 cooperate with the base 1 to clamp and fix the shoe last.

[0041] like Figure 2 and Figure 3 As shown, the clamping assembly includes: a mounting frame 23, a rocker arm 24, a fixing assembly and a clamping member, the mounting frame 23 is mounted on the corresponding side plate 21; the rocker arm 24 is pivoted to the lower end of the mounting frame 23; the fixing assembly is connected between the rocker arm 24 and the mounting frame 23, the clamping member is fixed to the rocker arm 24, and the fixing assembly can place the rocker arm 24 on the mounting frame 23 so that the clamping member can be held against the top of the shoe last to ensure that the shoe last is clamped.

[0042] like Figure 3 As shown, the fixing assembly includes: a hexagonal bolt 26, a washer 27 and a knurled nut 28. The hexagonal bolt 26 is threadedly connected to the mounting frame 23, and the lower end of the hexagonal bolt 26 extends downward after passing through the swing rod 24; the washer 27 is sleeved on the lower end of the hexagonal bolt 26; the knurled nut 28 is threadedly connected to the lower end of the hexagonal bolt 26, and the knurled nut 28 is abutted against the lower end of the washer 27. Screwing the knurled nut 28 can make the washer 27 press against the left end of the swing rod 24, thereby pressing the clamping member against the top of the shoe last, and clamping the shoe last on the base 1.

[0043] like Figure 4 As shown, the clamping member includes a connecting rod 291 and a positioning press head 292 which are integrally connected. The connecting rod 291 is fixed to the right end of the swing rod 24, and the positioning press head 292 can be supported on the shoe last.

[0044] Preferably, a plurality of anti-slip ridges 293 are provided at the bottom of the positioning pressure head 292 to increase the pressing effect of the positioning pressure head 292 and improve the fixing reliability.

[0045] In the embodiment of the present application, the rocker arm 24 includes a first rod body 241, a connecting rod body 242, and a second rod body 243 connected in sequence. The lower end of the hexagon head bolt 26 passes through the first rod body 241 and the washer 27 and is threadedly connected to the knurled nut 28. The connecting rod body 242 is pivotally connected to the lower end of the mounting frame 23 through the pivot shaft 25, and the connecting rod 291 is fixedly mounted on the second rod body 243.

[0046] like Figure 3 and Figure 6 As shown, a second through hole 2411 is formed on the first rod body 241 , a third through hole 271 is formed on the washer 27 , and the lower end of the hexagonal bolt 26 passes through the second through hole 2411 and the third through hole 271 in sequence and is connected to the knurled nut 28 .

[0047] In the embodiment of the present application, a second threaded hole 231 is formed on the mounting bracket 23 , and the hexagonal bolt 26 is threadedly connected to the second threaded hole 231 .

[0048] By providing the washer 27, the knurled nut 28 can be tightly held against the washer 27 when it is locked on the lower end of the hexagonal bolt 26, and the washer 27 is tightly held against the first rod 241 of the swing rod 24, thereby increasing the tightness of the connection between the knurled nut 28 and the hexagonal bolt 26. Since the first rod 241 and the second rod 243 are respectively located at the two ends of the swing rod 24, and the clamp is connected to the second rod 243, when the knurled nut 28 is screwed, the first rod 241 is tightened, and the clamp is also tightly held against the top of the shoe last, so that the clamp has a good fixing and pressing effect on the top of the shoe last.

[0049] like Figure 5 As shown, the second clamping mechanism 3 includes: a vertical plate 31, a plurality of pull rods 33, a clamping plate 35 and a plurality of compression springs 34. The lower end of the vertical plate 31 is fixed on the base 1; the plurality of pull rods 33 are slidably arranged on the vertical plate 31; the clamping plate 35 is connected to the plurality of pull rods 33, and the lower end of the clamping plate 35 is slidably matched with the slide groove 13 provided on the base 1, so that the clamping plate 35 can be held against the shoe last; the compression spring 34 is sleeved on the corresponding pull rod 33, and the compression spring 34 is held between the vertical plate 31 and the clamping plate 35. The arrangement of the compression spring 34 enables the clamping plate 35 to slide elastically on the base 1, so that when the shoe last is placed between the two clamping plates 35 opposite to each other at the front and back, the shoe last will squeeze the two clamping plates 35, so that the compression spring 34 is compressed, so that the elastic action of the compression spring 34 enables the two clamping plates 35 to tightly clamp the front and back ends of the shoe last.

[0050] Preferably, one end of the plurality of pull rods 33 away from the clamping plate 35 is connected with a pull plate 32 that is convenient for holding. Before placing the shoe last, the pull plate 32 needs to be operated to pull open the clamping plate 35 so as to accommodate the shoe last.

[0051] Preferably, an anti-skid pad 36 is provided on the clamping plate 35, and the anti-skid pad 36 can increase the clamping effect on the shoe last.

[0052] like Figure 1 and Figure 3As shown, a plurality of threaded holes 11 arranged in a line are provided on the left and right sides of the base 1, and a plurality of first through holes 211 corresponding to the threaded holes 11 are provided on the side panel 21. The first screws 22 can pass through the first through holes 211 and be fixed on the threaded holes 11 at different positions, thereby realizing the adjustment of the position of the side panel 21.

[0053] Preferably, the front and rear ends of the base 1 are both provided with slide rails 12 , and the side panels 21 are provided with grooves 212 that slidably cooperate with the slide rails 12 . By providing the slide rails 12 to cooperate with the grooves 212 , the side panels 21 can move more smoothly.

[0054] Working principle: first pull open the clamping plate 35 on one side, then place the shoe last between the two clamping plates 35, so that the pair of second clamping mechanisms 3 clamp the front and rear ends of the shoe last, then loosen the first screw 22 to move the side plate 21, so that the clamping member is located above the shoe last, after the position of the side plate 21 is adjusted, lock the first screw 22, and turn the knurled nut 28 to tighten it. In the process of tightening the knurled nut 28, the knurled nut 28 squeezes the washer 27, so that the washer 27 squeezes the swing rod 24, so that the swing rod 24 swings, so that the clamping member swings, and finally abuts against the top of the shoe last to clamp the shoe last. A pair of first clamping mechanisms 2 can tighten the top of the shoe last, and a pair of second clamping mechanisms 3 can clamp the front and rear ends of the shoe last, so the first clamping mechanism 2 cooperates with the second clamping mechanism 3 to reliably clamp the shoe last.
