INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a clamping device, and more particularly to a clamping device for a removable component. [Prior Art] Referring to Fig. 1, a general palm-type pneumatic tool 1 is taken as an example, and mainly includes a body 11, a piston rod 12, and a joint group 13. The body 11 has a ring wall 112 that defines a shaft hole U1 about an axis. The piston rod 疋 extends from the body 11 in the axial direction. The connecting group 13 has a ring seat 131 screwed to the ring wall 112 of the body 11, and a sleeve 132 that fits the ring seat 131. Thereby, when the nail 132 is inserted into the sleeve 132, the plunger 14 can be driven by the air pressure to fire the nail 14. Since the nails 14 have various specifications, the setting of the single sleeve 132 is often not applicable to the various nails 14, especially the nails 14 of a special specification. Therefore, in order to meet the practical requirements, it is necessary to prepare There are several sleeves 32 of different apertures that allow the operator to replace the use depending on the application. However, the sleeve 132 is engaged with the ring seat 131. Therefore, in order to replace the different sleeves 132, the entire group of the connection groups must be removed, and the other group of the connection groups 13 is replaced, resulting in standby. There are too many components, such as occupying space and being difficult to collect. It is important that the ring seat 131 is screwed with the body and must ensure the stability when it is fixed. Or the removal of the ring seat 131 must rely on the tool to achieve, and cause inconvenience in use. 5 1323694 [Invention] Therefore, the object of the present invention is to provide a clamping device capable of easily replacing components. Thus, the clamping device of the present invention is mounted on a body of a pneumatic tool. The clamping device comprises a clamping group, a clamping group, a springing group and a driving group. The connecting group has a socket. And a ring seat fixed to the body along the axis and engaged with the socket. The clamping group has at least one

The clamping members 41 are oppositely defined in the annular groove μ of the ring seat 31 around the axis, and respectively have a locking portion 411 extending along the radial direction and passing through the through hole 313 of the ring seat 31, A groove 412 is formed on one side and surrounds the axis, and a guide inclined surface 413 is formed at the end of the locking portion 4U. The guide slope 413 is inclined from a position away from the axis X toward a position adjacent to the axis χ. The drive group 5 has two contact members 51 and two bolts 52. The contact members are disposed opposite to each of the wire members 41, and (4) have a displacement hole 5Η extending in a parallel direction and extending in a radial direction, and a -step edge 512 forming a = surface. The check pieces 52 are respectively parallel to the sleeve line χ. After passing through the displacement hole 511, the bushing 32 is fixed, so that the contact (4) 7 1323694 51 is positioned and can only be displaced along the radial direction. The elastic group 6 has two elastic members 6 which are elastic and have a ring shape with respect to the axis, and have opposite -1 constrictions 611, respectively, and are formed therein. Two elastic portions 612 at the two ends of the compression portion 611. The compression portions 611 abut against the step=2 of the touch-contact member 51 and pass around the inside of the bolt 52. The elastic portions 612 are received in the grooves 412 according to the trajectories of the grooves 412 of the clamping members 41, respectively. Referring to FIG. 4, and FIG. 5 and FIG. 6, when the elastic members 61 are not subjected to external force, they will maintain the annular state by their own elastic restoring force. At this time, the locking portion 411 of the /etc. The through holes 13 passing through the ring seat μ are respectively engaged and blocked in the recesses 33 of the socket member 33 so that the socket members are blocked from the locking portions 411 of the clamping members 41, and cannot be disengaged from the ring seats. And only under the action of an external force, the grooves 331 follow the extension and displacement of the locking portions along the axis X direction, thereby obtaining the positioning of the socket member. Referring to FIG. 7, β 8, when The user is to be removed when the socket 33 is to be replaced. The pressing members 51 are simultaneously pressed by the fingers of one hand, and the displacement holes 5 依 are displaced along the axis by the misalignment member 52. At this time, the contact members η are respectively compressed by the edge 512 to compress the elastic Μ 61. The compressing portion 6 ιι, the ink-reducing portions 611 are inwardly contracted with respect to the axis X, and the elastic deformations are driven in conjunction with the driving of the elastic portions 612, and the central pressing members 41 are bent in the axis, so that the clamping is forced. The locking portion 411 of the member 41 is detached from the socket: the groove 331. In this way, the user can use the other hand to pull out the 8. It is worth mentioning that, instead of replacing the socket member 33, the t-piece 33 can be directly inserted into the ring seat 31 β. When the sleeve member 33 penetrates the % of the seat 31, the workpiece is forced to abut against the clamping member 41 so that the locking portion 411 of the clamping member 41 is centered on the axis X and cooperates with the guide The slope of the inclined surface 413 is outwardly expanded, and the locking portion 411 of the clamping member 41 is opposite to the groove 331 of the sleeve member 33, and is locked in the sleeve by the elastic restoring force of the elastic members 61. The recesses of the connector 33 are 3 Θ, and the action of the set can be completed. 9 and FIG. 10, FIG. 2 is a second preferred embodiment of the present invention, which is substantially the same as the first embodiment. The difference is that the central holding device includes a driving group that can replace the driving group 5 described above. 7. The clamping members 4i/ respectively have a slope 414 formed at the two ends and inclined from the top to the bottom and from the outside to the inside. The driving group 7 has a direction around the clamping members 41 and is displaceable in the axial direction. An annular contact member 71, and a push-pull i-hole 72 formed on an inner surface of the contact member η. The push-pushing blocks 72 are disposed opposite to each of the clamping members 41, and have the same The inclined surface 414 fits the two oblique pushing surfaces π. Therefore, when the clamping members 41* are pushed by an external force, they are maintained in a ring shape by the elastic restoring force of the elastic members, so that the clips are held. The locking portion 411 of the pressing member 41 is locked in the recess of the socket member 33. When the user pushes the contact member 71 upward along the axis, the contact block 72 of the pressing member 71: The inclined surface 721 pushes the inclined surface 414' of the gripping member 41 to cause the clamping members 41 to expand outward against the elastic force of the elastic members 61. Thereby, the locking portion 4 of the clamping member 41 can also be unloaded from the recess 331 of the sleeve member 33 by the 1323694, and (4) can also achieve the purpose of positioning and withdrawing the socket member 33. It can be seen that the clamping device of the present invention has the following advantages and effects: The present invention achieves the purpose of individually replacing the socket member 33 by pressing the driving group 5 or pushing the driving group 7 ' Free of the aids, it can improve the convenience of the replacement and the simple 'steep, and spare components, only need to cooperate
