The invention overcomes the defects of the prior art and provides the portable and simply-operated speed skating blade sharpener.
The technical scheme of the invention is as follows: the portable speed skating skates sharpener comprises a base, a rolling bearing, a bearing height adjusting washer, a bearing fixing nut, a scrap removing brush, a grinding plate fixing nut, a pressure spring, a grinding plate fixing screw rod, a grinding plate gasket, a bearing fixing adjusting window and a handle. The base is a section of square pipe, the central point of the panel of the base is transversely provided with two rolling bearing mounting holes which are arranged in parallel, the panel at the central point of the mounting positions of the grinding plates at the left side and the right side of the bearing mounting holes and the opposite bottom plate are provided with the grinding plate mounting holes, and the rolling bearing mounting holes of the opposite panel of the base bottom plate are provided with bearing fixing and adjusting windows.
The rolling bearing is a bolt type roller needle bearing or a bearing fixed by bolts, the two bearings are combined into a group, the thickness of the ice skate blade plate is used as the distance between the two bearings and fixed on the panel of the base, and the linear plane sliding rail grinder is formed by the two grinding plates which are fixed on the panel of the base at the left and the right.
The bearing height adjusting washer is composed of a plurality of thin washers, and the height of the bearing on the panel can be adjusted.
The bearing fixing nut is a nut for fixing the bearing on the panel and has the function of adjusting the distance between the bearings.
The scrap removing brush is four brushes fixed between the rolling bearing and the grinding plate.
The grinding plate is a square or round diamond grinding plate (only a square is drawn in the drawing, and a round shape is omitted), and the two grinding plates are in a group and are fixed on the panel in a shaft fixing mode through a fixing nut, a pressure spring and a screw rod which are fixed at the center of the grinding plate, so that the grinding plate can horizontally rotate on the panel and is used for balancing the abrasion of the grinding plate.
The grinding plate gasket is composed of a plurality of narrow sheets with the same length as the grinding plate width, and is arranged below the far end plate of the grinding plate for adjusting the radian required during the blade grinding.
The bearing fixing and adjusting window is a larger hole formed in the mounting position of the rolling bearing on the corresponding panel of the bottom plate.
The handle is a handle mounted on the base plate.
Due to the adoption of the technical scheme, the quick-skating cutter provided by the invention has the following beneficial effects:
1. compared with the existing knife sharpener, the volume is miniaturized, and the finished product can be put in a small storage bag or a pocket in an ice skate bag for carrying.
2. The blade sharpening machine is convenient and simple to use, can sharpen on site without special personnel and places, does not need the process that the prior sharpening machine firstly fixes the ice skate blade on the blade carrier and then detaches the blade carrier after sharpening, and saves time.
3. The grinding plate can grind straight or cutting edges with required radian by matching with the grinding plate gasket.

Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
FIG. 1 is a front view of the present invention
FIG. 2 is a sectional view of a fixing portion of a rolling bearing according to the present invention
FIG. 3 is a cross-sectional view of the grinding plate attachment of the present invention
FIG. 4 is a bottom view of the present invention
Referring first to fig. 1: the portable speed skating skates sharpener has the advantages that the linear sliding rail with the plane grinding function is formed by two rolling bearings (2) vertically fixed on the panel and two grinding plates (3) with two sides fixed on the panel, the two rolling bearings (2) and the two grinding plates (3) are vertically fixed on the panel, the blade of the skates faces upwards in practical use, the blade of the skates is clamped between the two bearings, the sharpener enables the grinding plates to press the blade to do reciprocating motion under certain pressure, the requirement that the two sides of the front plane of the blade are ground to form a standard 90-degree right angle is met, grinding scraps possibly adhered to the blade are brushed down by the scrap removing brush (4) fixed between the rolling bearings and the grinding plates, and the bearing surface and the blade surface are prevented from being damaged by the grinding scraps.
FIG. 2 is a sectional view of the rolling bearing fixed on the panel, the height of the bottom edge of the bearing is adjusted to be about 1 mm higher than that of the grinding plate by a bearing height adjusting washer (5), and the bottom edge is fixed on the panel by a rolling bearing fixing nut (6) with the distance equal to the thickness of the cutter plate.
Fig. 3 is a sectional view of the grinding plate fixed on the base, the panel and the bottom plate are provided with upper and lower opposite mounting holes relative to the grinding plate fixing nut (7), a pressure spring (9) is penetrated on a screw rod (8), the screw rod is screwed on the grinding plate fixing nut through the bottom plate to form shaft fixation, the grinding plate can be subjected to plane conversion at any angle under the fixation, the purpose is to balance the abrasion degree of each part of the grinding plate, and the structure is also beneficial to quickly replacing different grinding plates.
