DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a roller device, and more particularly to a roller device for a generator. [Prior Art] Generally, the fixed generator is placed on the ground and is not easy to move. In particular, the size and weight of the generator are very large. If the auxiliary moving mechanism is lacking and is directly transported by human power, it will inevitably cause difficulty in handling. Therefore, Some operators have designed a mobile generator to facilitate user handling. Tea reading Figure 1 'The conventional mobile generator 1 is equipped with four push wheels 11 at the bottom (only three are drawn in the view), so that the user can push the private transport, however, The design method has the following disadvantages: (1) The generator 1 is not easily placed on the uneven ground: because the pusher u is fixed to the bottom of the power generating 胄i, once the ground is uneven, The push wheel 11 will form a rolling, and the hair "1 is not easy to be placed on the ground smoothly" is very easy to cause a sloshing phenomenon due to a slight touch. The lean motor 1 is easy to slip: since the push wheel U does not have positioning Function, so the user can easily and easily push the generator i, but in contrast, this also means that the thick rubbing force of the seat of the six-way a gate between the push wheel 11 and the ground is relatively small, even if the generator 1 In the course of use, due to the external force push or the movement of the 忭 忭 忭 而 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 产生 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 盥 裕 裕 裕 裕 裕 裕 裕 裕, causing electric shock, etc., causing cremation and splashing, resulting in fire Accident. 5 l299〇3i (3) The product of the side generator 1 is relatively large: the push wheel 11 is located outside the bottom of the generator 1, so in addition to the generator! Outside the volume itself, the push wheel u also occupies the space outside the generator 1 so that the mobile generator 1 has a larger product volume than the conventional fixed generator. Therefore, how to overcome the above shortcomings has become an urgent need for research. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a roller device for a generator that not only facilitates the user to push the generator, but also that the roller device can be placed in a state of being placed such that the generator is placed directly on the ground. It is not easy to produce slippage. Thus, in the roller device of the generator of the present invention, the generator is housed in a frame, the roller device is disposed at the bottom of the frame, and includes a plurality of roller members that can roll along the ground, and a plurality of A connecting unit of each of the roller members and the frame is connected separately. Each connecting unit has a sleeve member fixed to the frame and hollow inside, a lifting shaft passing through the sleeve member and movable longitudinally thereof (4), and a fixing member traversing the sleeve member The bottom end of the lifting shaft is fixed to one of the roller members, the fixing member being detachably contacting the lifting shaft to position the lifting shaft in the sleeve member. The effect of the invention is that when the generator is to be pushed, the frame forms a space with the ground, and the roller member protrudes outside the frame and rolls on the ground to facilitate the user to push the generator. When the machine is parked on the ground, the roller member is stored in the frame, and the frame is directly placed on the ground, and the roller member is combined with the roller member to form a plurality of points. The effect of the slamming, which in turn makes the generator less prone to slip, whereby the generator can be moved to a suitable location and placed in place. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are related. The present invention is presented in the following detailed description of the preferred embodiments with reference to the drawings. π Referring to Figures 2 and 3, a preferred embodiment of the roller device 2 of the generator 31 of the present invention, the generator 31 (shown in Figure 3) is housed in a frame, and the roller device 2 is divided into The frame 32 and 6 are inserted into the bottom of the humanized wood 32, and include four roller members 21' which can be rolled along the ground, and four links for the eight-blocking mouth to respectively connect each of the roller members 21 to the frame 32. Unit 22, in the figure is a square #间甲 for convenience of description, only one of the lightning machine 31 and the frame 32 is drawn, that is, one of the roller members 21 and the mouth, the mouth is 7G 22, the cross Above, a parent roller member 21 and a coupling unit 22 are respectively disposed at four corners of the lightning-sliding head 31. The female connector 22 has a sleeve member 221 fixed to the frame, a lifting shaft 222 which is erected and has a longitudinal movement in the interior thereof, and a crossing shaft 222. a μ μ μ 曰 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 四 四 四 四 四 221 221 221 221 221 223 223 223 223 223 223 223 223 223 223 223 The sleeve member 221 has a head 盍 224 which is lowered by 999 ρ, and a set of elastic member milk ew u ^ ^ ^ 设 上 222 222 222 222 222 222 222 弹性 弹性 弹性 弹性 弹性 弹性 弹性In the embodiment, only the first and second elastic members 225 7 1299031 and 226 are - springs, and the sleeve member 221 is formed with a screw hole milk, and the fixing member 223 is a movable screw. The bolts that extend through the screw holes 227 are worn. The lifting shaft 222 is formed with a plane (10) facing the fixing member 223, and a protrusion 229 is formed adjacent to the bottom end to abut the outer bottom edge of the sleeve member 22, and the plane 228 is recessed inward. A positioning groove 230 is formed. The head cover 224 and the protruding portion 229 cooperate to allow the lifting shaft 222 to be longitudinally moved within the sleeve member 221 by a set distance. The first elastic member 225 of each of the connecting units 22 has its two ends respectively contacting the outer bottom edge of the sleeve member 221 and the protruding portion 229 of the lifting shaft 222. The second elastic member 226 is sleeved on the fixing member. The 223 is located outside the screw hole 227, and the two ends thereof respectively touch the fixing member and the sleeve member 221. Each roller member 21 has a moving wheel 211 and an axle 212. The two ends of the wheel shaft 212 are respectively Threaded and formed at the same time through the bottom end of the lifting shaft 222 and the moving wheel 211, and then the two screw heads 213 are respectively screwed at the two ends of the wheel shaft, so that one end of the wheel shaft 212 is locked The other end of the bottom of the lifting shaft 222 is pivotally disposed on the moving wheel such as i, thereby fixing the lifting shaft 222 and the roller member 2]. Referring to FIGS. 3 and 4, when the generator 31 is to be pushed, the fixing member j23 is firstly formed in a state of being loosely released from the screw hole 227 of the side sleeve member 221, and the lifting shaft 222 can be freely operated on this day. The sleeve member 221 slides up and down, and the user raises the generator 31 and the frame 32. The sleeve member 221 is moved upwards, and the lifting shaft 222 is biased by its own gravity and the elastic force of the first elastic member 225. Move down until the head cover 224 touches the outer top edge of the sleeve member 221, and the lifting shaft 222 does not continue to move down, and then the fixing member 223 is locked and inserted. The positioning groove 23 is inside, in such a manner that the lifting shaft 222 is positioned in the sleeve member 221. The first elastic member 225 is formed into a moderately stretched state by its own elastic tension, and its two ends respectively touch the outer bottom edge of the sleeve member 22 and the protruding portion 229 of the lifting shaft 222. 2U protrudes from the outside of the frame 32 and rolls along the ground, so that the frame 32 is spaced from the ground, so that the user can easily and conveniently use the moving wheel 211 of the roller member 21 to roll relative to the ground, thereby facilitating labor saving. The generator 31 is pushed to the ground. Further, when the fixing member 223 is traversed through the sleeve member 22, the fixing member 223 and the sleeve member 221 may be provided by the second elastic member 226. It does not directly contact the wearer, reduces the wear, and can also adjust the pressing force between the fixing member 223 and the lifting shaft 222 < and can also effectively prevent the generator 31 from vibrating during operation so that the fixing Piece 223 forms a loose. Referring to Figures 5 and 6, when the generator 31 is to be parked on the ground, the fixing member 223 is first appropriately loosened to be disengaged from the positioning groove 23, and the generator and the frame 32 will be Moving downward because of its own weight', the sleeve member 221 is moved downwards until the frame 32 is in direct contact with the ground, and the first elastic member 225 is the outer edge of the sleeve member 221. And the protruding portion (10) of the lifting shaft 222 is compressed, and the (four)-elastic elastic restoring force can be pushed down by the elastic restoring force of the first elastic member 225 even if the ground surface exhibits a rugged state as shown in FIG. The protrusion 229 of the lifting shaft 222 is adjusted to 9 1299031, and the lifting shaft 222 is automatically adjusted to an appropriate position to drive the moving wheel 211 to adjust its height with the height of the ground automatically and smoothly placed on the ground. The fixing member 223 is again locked against the plane 228 of the lifting shaft 222. With this design, the moving wheel 211 is in the storage state in the frame 32, and the frame 32 is directly placed on the ground, and cooperates with the moving wheel 211 to form a plurality of points for the generator 31. The generator 31 can be placed on the ground smoothly, and it is not easy to cause slippage due to external force pushing or vibration during use. With the above design, the present embodiment has the following advantages: (1) The generator 31 can maintain a good balance state with the ground level: 'When the generator 31| is placed on the ground, Even if the ground is in a state of unevenness, the height of the lifting shaft 222 can be adjusted by the elastic restoring force of the first elastic member 225 of each connecting unit 22, thereby driving the moving wheel 211 to adjust with the height of the ground. The height is placed on the ground smoothly, so that the generator 31 maintains a fairly good balance. (2) The roller device 2 can be mounted on the general generator 31 without

Since the four connecting units 22 are respectively disposed at the four corners of the generator 31, the user can change and adjust each connecting unit one by one. The twist of the lifting shaft 222 of 22 is used to push or position the generator 31 without the help of others, thereby effectively improving work efficiency. (4) When the generator 31 is placed and positioned, slippage is not easily generated: when the generator 31 is placed and positioned, not only the frame 32 is directly placed on the ground to support the hair, and the four-shift (four) 2 ι is also Four-point symmetrical support can be formed. In this way, each of the moving wheels hi and the frame 32 bears the weight of the generator 31, and is ground-shaped: a considerable frictional pressure, even if an external force is pushed against the generator 31. Or the generator Μ operates to generate vibration, and does not cause slippage, and the generator 31 can be smoothly placed on the ground to improve the stability thereof. The above-mentioned, the roller of the generator 31 of the present invention is summarized. The device 2 can not only adjust the height of each moving wheel 211 according to the height of the ground, but also maintain the balance of the generator 31 as a whole, and can also be installed on the general generator η without affecting the product volume thereof, and The person can push or position the generator 31, and the work efficiency can be effectively improved without the help of others.
