[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1 , Figure 2 As shown, an adjustable knife holding device for a freezing slicer comprises a base 1, a horizontal transverse slide 2, an angle adjustment platform 3, and a horizontal longitudinal slide 5 arranged in sequence from bottom to top. The top of the base 1 is slidably connected to the horizontal transverse slide 2, so that the lateral movement adjustment of the blade can be realized. The top of the horizontal transverse slide 2 is provided with an arc concave surface, and the bottom of the angle adjustment platform 3 is provided with an arc convex surface, i.e., a bottom sliding contact surface 32. The arc concave surface and the arc convex surface are slidably connected, so as to realize the angle adjustment of the blade. The bottom of the horizontal longitudinal slide 5 is slidably connected to the top of the angle adjustment platform 3 (i.e., the top sliding contact surface 31), so that the longitudinal movement adjustment of the blade can be realized. The blade is installed on the top of the horizontal longitudinal slide 5. The sides of the base 1, the horizontal transverse slide 2, the angle adjustment platform 3, and the horizontal longitudinal slide 5 are all provided with a locking wrench 4. After the blade position is adjusted, the internal pin is driven to lock its position by rotating the locking wrench 4 (this is the prior art).

[0027] like Figure 3 - Figure 7As shown, the top and bottom sliding contact surfaces of the angle adjustment platform 3 are the top sliding contact surface 31 and the bottom sliding contact surface 32, respectively. In order to achieve the lubrication effect between the angle adjustment platform 3 and the horizontal transverse slide 2 and the horizontal longitudinal slide 5, a plurality of oil holes 34 are arranged through the inside of the angle adjustment platform 3. The plurality of oil holes 34 are arranged in a straight line, and the plurality of oil holes 34 are divided into two groups. The two groups of oil holes 34 are respectively located on both sides of the angle adjustment platform 3, and the oil holes 34 in each group are arranged equidistantly. The upper and lower ends of the oil hole 34 are connected to the top sliding contact surface 31 and the bottom sliding contact surface 32, respectively. An oil storage cavity 35 is provided inside the angle adjustment platform 3, and the oil hole 34 runs through the oil storage cavity 35, and the oil storage cavity 35 is connected to the oil hole 34. A siphon 36 is embedded in the oil hole 34, and the siphon 36 includes a support rod 361 and a sponge column 362. The sponge column 362 is fixedly connected to the outside of the support rod 361, and the support rod 361 provides support for the sponge column 362, so as to facilitate the insertion and removal of the oil hole 34. The sponge column 362 is cylindrical, and the upper end of the sponge column 362 extends to the top sliding contact surface 31, and the lower end of the sponge column 362 extends to the bottom sliding contact surface 32. The lubricating oil in the oil storage chamber 35 can be transported to the top sliding contact surface 31 and the bottom sliding contact surface 32 through the siphon effect of the sponge column 362, so as to achieve lubrication of the top sliding contact surface 31 and the bottom sliding contact surface 32. Furthermore, at least two shrinking rings 38 are arranged inside the oil hole 34, and the shrinking rings 38 are located on the upper and lower sides of the oil storage chamber 35 and are located near the oil storage chamber 35. The shrinking rings 38 can limit and squeeze the sponge column 362. On the one hand, it can keep the siphon member 36 fixed, and on the other hand, it can prevent the lubricating oil in the oil storage chamber 35 from pouring into the oil hole 34.

[0028] like Figure 5 , Figure 6 As shown, one end of the oil storage chamber 35 penetrates to the side of the angle adjustment platform 3, and a cover 33 is installed at the port of the oil storage chamber 35. A sealing ring 37 is installed on the cover 33, and the cover 33 is threadedly connected to the port of the oil storage chamber 35. The setting of the cover 33 facilitates the injection of lubricating oil into the oil storage chamber 35. After the oil storage chamber 35 is filled with lubricating oil, the lubricating oil in the oil storage chamber 35 is transported to the top sliding contact surface 31 and the bottom sliding contact surface 32 through the siphon effect of each siphon member 36, providing a lubricating effect for the contact surface until the lubricating oil in the oil storage chamber 35 is consumed. Therefore, the lubrication maintenance cycle is improved and the frequency of lubrication maintenance is reduced.
