[0024] Please refer to Figure 1 , Figure 4 - Figure 5In the embodiment, the blocking mechanism comprises a second connecting seat 31 fixedly connected to the front face of the placing frame 24, a worm 32 rotatably connected to the second connecting seat 31, a handle 33 fixedly connected to the top of the worm 32, a worm wheel 34 engaged with the outside of the worm 32, a rotating shaft 35 fixedly connected to the inside of the worm wheel 34, the rotating shaft 35 rotatably connected to the placing frame 24, a baffle 36 fixedly connected to the rotating shaft 35, and the baffle 36 is inclined to allow the bar to enter the inside of the placing frame 24. The bar is guided by the baffle 36 to enter the inside of the placing frame 24 in a form perpendicular to the front inner surface and the back inner surface of the placing frame 24, so as to avoid the inclination of the bar. The placing frame 24 is provided with an adaptive limiting hole at the corresponding position of the rotating shaft 35, and the rotating shaft 35 rotates in the limiting hole. The adaptive limiting hole allows the rotating shaft 35 to rotate stably, so that the inclination angle of the baffle 36 can be flexibly adjusted, and the baffle 36 can be applied to bars of different sizes.

[0025] In operation, the bar is first placed in the gap between the baffle 36 on the left side and the placing frame 24, so that the bar is perpendicular to the front inner surface and the back inner surface of the placing frame 24.
