[0021] Such as Figures 2-4As shown in the figure, a plurality of chip removal grooves 45 are provided on the upper surfaces of the two bearing platforms 42. Activity grooves 48 are provided at the corresponding positions of the inner side walls of the fixed seats 41 and the sliding paths of the fixed columns 46. A sliding rod 47 is connected to the outer surface of the fixed column 46. Telescopic grooves 401 are provided at the corresponding positions of the inner side walls of the activity grooves 48 and the sliding paths of the sliding rod 47. Connecting springs 49 are connected to the outer surface of the sliding rod 47 and located on the inner side walls of the activity grooves 48. An adjusting member 402 is connected to the outer surface of the fixed column 46. Two limiting columns 403 are connected to the upper and lower surfaces at both ends of the fixed seat 41. Engaging grooves 404 are provided at the corresponding positions of both ends of the adjusting member 402 and the sliding paths of the limiting columns 403. The inner diameter size of the activity groove 48 is adapted to the sliding path of the fixed column 46. The inner diameter size of the telescopic groove 401 is adapted to the sliding path of the sliding rod 47. The outer diameter size of the limiting column 403 is adapted to the inner diameter size of the engaging groove 404. It should be noted that the cooperation between the engaging grooves 404 of the two adjusting members 402 and the limiting columns 403 can limit and fix one end of the bearing platform 42. The bearing platform 42 connected by the connecting spring 49 and the sliding rod 47 can slide automatically, realizing the inclination of the two bearing platforms 42, so as to facilitate cleaning.

[0022] As Figures 2-3 shown in the figure, two connecting blocks 407 are connected to the bottom surfaces at both ends of the fixed seat 41.
