Haidi's one-bit #18 is longer. The Miyazaki 2 contains - a resist 21, a miscellaneous element 22 and a = ^3. The other section of the coupling shaft 2 has a smaller diameter and the smaller section of the coupling shaft 2, and the intermediate section of the abutting shaft 21 can be a wide average. Referring to FIG. 3, the elastic member 22 can be pressed;", and the inner width of the elastic member 22 is larger than the abutting shaft 21, and the segment is smaller than the head portion 211. The end portion of the elastic member 22 abuts against the head portion 211 of the abutting shaft 21. Further, the through hole (6) of the bracket 16 has a larger diameter than the elastic portion. The outer diameter of the element 22 is wide, so that the abutting shaft 21 and the elastic member 22 can be protruded from the top surface of the bracket 16 by the teeth 161. The positioning member 23 has a through hole 231. The through hole 231 is slightly larger than the diameter of the middle portion of the abutting shaft 21 and smaller than the inner diameter of the elastic member 22; the positioning member 23 is coupled to the abutting shaft 21 through the through hole 231 The bottom side of the bracket 16 is such that the other end of the elastic member 22 can abut against the positioning member 23, and the elastic member 22 can be in an uncompressed or slightly compressed state. In this embodiment, the lock is transmitted through several locks. The fixing member 5' locks the positioning member 23 to the bottom side of the bracket 16. Referring to Figures 2 and 3, the roller assembly 3 includes a wheel base 31 and at least The roller 32, the wheel base 31 of the roller assembly 3 is combined with the driven component 2 phase M413484, the at least one roller 32 is coupled to the wheel base 31, and the at least one roller 32 is preferably a universal wheel to enhance the user. The convenience of the operating table is changed. In the present embodiment, in order to effectively utilize the accommodating space 13 of the base 1, the wheel base 31 can be centrally recessed, and a roller 32 can be connected to each end of the wheel base 31. The center of the wheel base 31 is provided with a coupling hole 3n. The diameter of the coupling hole 3 ι is slightly larger than the joint portion 212 of the abutting shaft 21, so that the abutting shaft 21 can penetrate the joint portion 212 into the joint hole 311. And the locking shaft 21 is firmly coupled with the wheel base 31 by the locking component 5. Referring to Figures 2 and 3, the driving assembly 4 includes an operating rod 41, a connecting block 42 and a spinning member. The operating lever 41 is pivotally connected to the connecting block 42 . The operating lever 41 and the connecting block 42 are disposed outside the base. The scraping member 43 s is disposed in the receiving space 13 of the base 1 . The spinning member is coupled to the connecting block 42 through the side panel 12 of the 亥Hui base 1. In the embodiment, the connecting block 42 is provided with a The pivoting groove 421 and the engaging hole 422, one end of the operating rod 41 is pivotally connected to the frame rotating groove 421, so that the operating lever 41 can be pivoted in the pivoting groove 421. The rotating member 43 has a shaft portion 431. And a pressing portion 432, the diameter of the pressing portion 432 is larger than the diameter of the sea shaft portion 431, and the rotating member 43 passes through the shaft portion 431. The side plate 12 of the base 1 is coupled to The engaging hole 422 of the connecting block 42; wherein, in order to avoid relative rotation between the rotating member 43 and the connecting block 42, the cross-sectional shape of the shaft portion 431 and the engaging hole 422 may be correspondingly set to a non-circular shape. Further, the axial surface of the pressing portion 432 of the spinning member 43 is. The X sighs one of the arc-shaped pressing grooves 433, and the abutting groove 433 can abut against the head 211 of the abutting wheel 21. Referring to FIG. 3, when the assembly is set, the pedestal can be inverted first, and the _8 traverse member 43 is pierced from the inner side of the 5 hoisting base 1 to be opposite to the connecting block 42 and will be closed. The operating rod 41 is coupled to the connecting block 42 , and the elastic element 22 is continuously engaged with the abutting shaft 21 , and the abutting shaft 2 ι passes through the bracket i 〇 ' to make the head of the abutting shaft 21 The 211 is coupled to the pressing groove 433 of the spinning member 43, and the positioning member 23 is sleeved on the abutting shaft 21 and locked to the pallet 16, and finally the wheel base 31 is coupled to the abutment. The knot of the shaft 2 is 212. After the element is set, the adjustment member 142 can be adjusted so that each of the support and the seat 14 can firmly abut the ground and maintain the substrate n of the base 1 in a horizontal state. At this time, each of the rollers 32 is kept at a preset distance from the ground, so that the operating table is in a state of being fixed and incapable of being secreted, and the operating lever 41 can be maintained parallel to the side panel 12 and located above the first positioning rod 17. (As shown in Figure 4). In the fifth diagram of Mingmaizhi, when the operating table is to be switched to the movable state, the user can pull the operating rod 41 outward so that the free end of the operating jaw 41 can be pivotally connected to the pivoting slot 421. The end portion is centered, and an arc-shaped X flat position is generated until the operating lever 41 moves to a range other than the first positioning rod ,, and the operating lever 41 is pressed downward. °月参'匕图图6, when the operating rod 41 is pressed downward, it can be restricted by the second positioning rod 18 without moving downward by an excessive distance; in the over-twisting of the operating rod 41, the operation The rod 41 can drive the connecting block to rotate, and at the same time, the screw 43 which is coupled to the connecting block 42 also rotates, so that the slot 433 of the 5th lands 43 is gradually spliced to the head 21 of the 21! The abutting portion 432 of the dust-removing member 43 is not provided with a portion that resists the groove state, and abuts against the head portion 211 of the abutting shaft 21. Therefore, the head 211 of the abutment * 21 is displaced by the pressing force, and the rotating element 22 assumes the state _ the roller member 3 is moved by the offset 21 to make the wheel 32 and the ground system. Going forward and stepping the foot of the foot 14 off the ground to change the operating table into a direction? The user can press the operating lever 41 to the side panel 12° to make the lever 41 abut against the first positioning rod to maintain the roller 32 in contact with the ground. . Conversely, when the operating table is moved to a fixed point, the user can operate: 41 an outward shifting 'and moving back to the first positioning rod' on the second; the resetting of the H-series 22 to make the abutting shaft 21 Moving upward, the head 211 of the abutting shaft 21 is again restored to a state in which the spinning member * =: (as shown in FIG. 3) is in a state in which the roller assembly 3 cannot be moved.壬 疋 疋 · · · · · · · · · · · · · · · · · · · 练 练 练 练 练 练 练 练 练 练 练 练 练 练 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本The clock is only rolled out: the inside is extended, and the operating table is swayed _ can be connected _, two: one member, the manufacturing cost of each base of the matching dream 2 Therefore, the base of the operating table created by the handbook can be lowered, and when the operating table is to be moved, only the components of the drive unit of the 1 _._roller assembly 3 are supported by each other (10) Significantly reduce the occurrence of wear or crack between components, which has the effect of improving the service life of the operating table base. ^Although this creation has been utilized The present invention is not limited to the scope of the present invention, and various modifications and changes to the above embodiments are still protected by the present invention. The technical scope, therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application.
