The casing 10 has a peripheral wall 12 defining a space U, a first shaft hole 13 extending through the peripheral wall 12 and passing through the driving wheel 12 into the space u, and a penetrating through the peripheral wall The drive shaft 210 is threaded into the second shaft hole 14 in the space 11. The output unit 20 has a sleeve 21 axially disposed on the peripheral wall 12, a first drive wheel 22 fixed to the sleeve 21, and a first fixed drive wheel 22 fixed to the sleeve 21 and axially disposed on the first drive wheel 22 second drive wheel 23 on one side. The sleeve 21 is hollow in shape and has a pair of coupling holes 211 corresponding to the second shaft hole 14 and engaging and coupling the transmission shaft 21 of the spindle unit 200, and an inner circumferential surface defining the coupling hole 211 212 and a plurality of bolt teeth 213 disposed on the inner circumferential surface 212 and interfitting with the bolt slots 220. The first and second driving wheels 22, 23 of the embodiment have different numbers of teeth, and the first driving wheel The number of teeth of 22 is less than that of the second drive wheel 23. The shifting unit 30 has a shaft (4) 31, -31 disposed on the peripheral wall 12 and on the side of the sleeve 21, and is disposed on the shaft 31 and is coupled to the driving wheel 12. a toothed transmission wheel 32, a sleeve axially slidable along the shaft 31, a first shifting wheel 34 fixed to the sleeve 33, and a second shifting wheel 35 fixed to the sleeve . The shaft 31 has a plurality of bolt grooves 3 ι. The sleeve η has a plurality of teeth 33 that are disposed on the (four) face and engageable with the bolt grooves 3u of the shaft 31, and can be along the shaft 31. - a movement between the two positions, in the first position, the first shifting wheel 34 meshes with the first driving wheel 22 (see Fig. 2), and in the second position, the first shifting wheel 35 The second drive wheel 23 is engaged (see Fig. 6). Referring to FIG. 4', the driving member 4A of the present embodiment is a pressure cylinder, and has a cylinder 41 fixed to the ^1G, which can be extended or retracted relative to the inspection body 41 and parallel to the distal shaft 3 a piston rod 42 of i and a dial block 43 mounted at the end of the piston rod 42. The dial block 43 has an inverted u-shaped cross section and has a card slot 431 for the first shifting wheel 34 to be nested. The extending or retracting action drives the sleeve 33 to move between the first and second positions along the axial direction of the shaft 31. As shown in FIG. 5, the spindle shifting device can be pre-assembled in a modular manner and the output unit 2〇, the shifting unit 30 and the driving member (not shown in FIG. 5, see FIG. 3) have been assembled.
