[Prior Art] One of the most common types of skateboards today is a four-wheeled skateboard. The skateboard has four rollers at the front and the back, which have excellent operational stability. However, when used, the four-wheeled skateboard is used. The person must use the foot to step on the ground to help the skateboard advance, and the operation sensitivity is not good. In addition, the plate body of the four-wheeled skateboard is made of wood, which is difficult to process and has high processing cost. Therefore, the shape of the plate body is usually quite monotonous and lacks variability. Furthermore, the manufacture of panels from wood panels can also cause environmental problems in tree felling. In addition, the industry has also introduced a two-wheeled skateboard with a roller at the front and the rear. However, before and after the two-wheeled skateboard are on the same straight line, the skateboard only touches the ground at two points. Therefore, the stability is low, the use is difficult, and considerable skill is required. [New content] The purpose of this creation is to provide a twisting type skateboard that has both operational sensitivity and stability. The user drives the slider to move by twisting the slider. Another object of the present invention is to provide a twisted slide which has good structural strength and can withstand a large load. The skateboard provided by the present invention comprises: a plate body, a front wheel unit, and a rear wheel unit, wherein the plate body is an elongated body; the front wheel unit has a front wheel rotatably disposed at a front end of the bottom surface of the plate body. And a front roller rotatably disposed on the front wheel fork, such that the front wheel unit can be rotated 360 degrees; the rear wheel M416487 unit has a rear wheel shaft disposed on a bottom surface of the plate body, and the two are rotatably disposed respectively The rear roller at both ends of the rear axle. Thereby, the skateboard contacts the ground at three points, which is relatively stable and convenient to use; especially importantly, the user tilts the plate body to the left side and the right side, so that the front wheel unit is deflected correspondingly to the two sides, so that the skateboard naturally leads to Move before. The bottom surface of the plate body can be formed into a concave-convex shape to improve its load capacity; the plate body can be made of a plastic material. [Embodiment] The purpose of the present invention, the features, and the effects achieved by the present invention may be described in detail with reference to the accompanying drawings, wherein: FIG. 1 is a perspective view of a preferred embodiment of the present invention. The second drawing is an exploded perspective view of the first figure. The third figure is a bottom perspective view of the first figure. The fourth picture is a bottom perspective view of the top of the creation. The fifth picture is a side view of the skateboard of this creation. The sixth picture is a longitudinal section of the skateboard of the present creation. The seventh drawing is a sectional view taken along line 7-7 of the sixth drawing. The eighth and tenth views are the front view of the creation and show that the board is tilted to one side. The ninth and eleventh figures are the top views of the eighth and tenth figures, respectively, showing that the front wheel unit is deflected to one side. Referring to the first to third figures, a twisting type sliding plate according to a preferred embodiment of the present invention comprises: a plate body 10, a front wheel unit 20 and a rear wheel unit 30. The plate body 10 extends in the direction of the front and rear ends to form an elongated body, and has a bottom plate 11 and a top plate 12 disposed on the top side of the bottom plate 11. In this embodiment, the material of the plate body 10 is plastic. Preferably, the bottom plate 11 and the top 4 M416487 plate 12 are made of acrylonitrile-butadiene-styrene copolymer (abs, Acrylonitrile-Butadiene). -Stryene). Further, it is to be understood that the slab body 10 can also be integrally molded by injection molding. The bottom surface of the bottom plate 11 is provided with two elongated ridges m, such as the third and seventh figures, which are located on two sides of the bottom plate and extend along the longitudinal direction of the bottom plate; a groove 112 formed on the two convex portions Between the strips m, the groove 112 is located at the center of the bottom plate; a plurality of support ribs 113 are disposed in the groove 112. By the arrangement of the rib 111 and the groove 112, the cross section of the bottom plate U has a convex-concave shape, which can enhance the structural strength and load of the bottom plate 11. In addition, a protrusion 114 is disposed at the front end of the bottom surface of the bottom plate 11 and has a slope 115 inclined upwardly. As shown in the fifth figure, the angle of inclination 0 of the slope 115 is between 1 degree and degree. Preferably, 15 to 25 degrees; the two ribs 111 are located behind the boss 4 . The inside of the bottom plate 11 is hollow, thereby reducing weight; a plurality of ribs 116 are disposed inside the bottom plate. The configuration of the boss 114 also enhances the structural strength of the bottom plate u and improves the impact resistance of the plate body 10. The ridges lu and the grooves U2 are located between the front wheel unit 20 and the rear wheel unit 30. The bottom surface of the top plate 12 is provided with a plurality of ribs 122, such as the fourth figure; the ribs 113, 116 and 122 are used to reinforce the structural strength of the bottom plate u and the top plate 12. The top plate 12 is fixed to the top side of the bottom plate by screws or other means. A sliding member 14 is in the form of a sheet having the same shape as the top surface of the plate body 1; a rough sliding surface is provided on the top surface of the sliding member 14. The anti-slip member is disposed on the top surface of the top plate 12 in such a manner as to be adhered to provide an anti-slip effect. The front wheel unit 20 has a front wheel 21; a front roller 22 pivotally mounted to the wheel fork 21. The rotating shaft 211 of the front fork 21 is pivotally disposed on the inclined surface 115 of the boss 114 of the bottom plate u. As shown in the fifth figure, the front fork 21 can be rotated 360 degrees on the bottom plate, so that the user can manipulate the traveling direction of the sliding plate. Since the convex 5 M416487 seat 114 has the inclined surface 115, the rotating shaft 211 of the front fork 21 is not upright, but the corner is inclined rearward. The rear wheel unit 3 has a wheel base 31 fixed to the bottom end of the bottom plate n; a top end of the mandrel 32' is connected to the wheel base 31; a rear axle 33 is mounted on the bottom of the spindle 32 The two rear rollers 34 are respectively pivotally disposed at the two ends of the rear axle 33. The rear wheel unit 30 is disposed at an inclined position of the bottom plate 11 which is inclined rearwardly upward by 5 degrees, for example, by $15 degrees; so that the mandrel 32 is also inclined rearwardly by the $ angle. When in use, please refer to the eighth to eleventh figure, the user standing on the plate body 10 of the skateboard to change the position of the center of gravity by twisting the body, and tilting the plate body 10 to the left or the right side can make the front wheel of the wheel unit 2丨 yaw to the left or to the right, so that the skateboard can be moved forward without stepping on the ground to help slip. The rotating shaft 211 of the front fork 21 is designed to be tilted to allow the front fork to rotate sensitively. The mandrel 32 of the same 'rear wheel unit 30' is designed to be inclined, which also makes the rear wheel unit easily deflected relative to the plate body 1G. Through the above description, the present invention has the following advantages: 1. The front and rear roller units 20' 30 of the present invention form the three-point cutting action of the slide plate not on the same line, and therefore, have good stability and are easy to use. =, the user pushes the skateboard by pushing the body and tilting the board 10, and does not need to step on the ground to assist in sliding. The front roller 22 can perform 36G rotation with respect to the plate body with operational sensitivity, which is convenient for the user to control the traveling direction. 2. The plate body 10 of the present invention is made by plastic injection molding, and the manufacturing and processing are uniform. Easy to fast' can reduce the manufacturing cost, and it is easy to create various * identical appearances on the board body, and it will not cause environmental protection for tree felling.
