Specifically, rack includes first support 11, second support 12 being fixed relative to first support 11 and fixture mounting seat 13 being fixed relative to first support 11. First support 11, second support 12, fixture mounting seat 13 can be fixed on the same machine seat simultaneously, can also be installed on the ground of workshop.

[0019] Workpiece fixed clamp 3 can be composed of 2 electric clamping jaws or 2 pneumatic clamping jaws, and is respectively clamped at the two sides of shoe forefoot and the two sides of shoe hindfoot. With pneumatic clamping jaw as an example, at least two inverted T-shaped grooves are arranged on fixture mounting seat 13 along front-back direction, and screw is installed in inverted T-shaped groove to fix pneumatic clamping jaw.

[0020] The working principle of the test mechanism is as follows: first, install sports shoes on workpiece fixed clamp 3, then drive mechanism works, drive friction consumable 5 reciprocating and friction corresponding sole, i.e. the bottom of shoe on first workpiece fixed clamp 3 is tested. In this way, the wear condition of shoe when intermittently subjected to forward friction force and backward friction force can be well simulated.

[0021] Referring to Figure 2 First support 11 is provided with movable base plate 61, and base plate 61 is provided with consumable support 62, and friction consumable 5 is installed at the lower end of consumable support 62, and drive mechanism is connected with base plate 61 to drive base plate 61, consumable support 62 and friction consumable 5 to reciprocate along left-right direction. Further, guide rail is arranged on first support 11, and sliding block matched with guide rail is fixed on base plate 61.
