The axial member 2 is disposed on the upper portion of the seat body 1, the axial member 2 is provided with a plug hole 21 along the vertical direction, the sidewall of the axial member 2 is provided with a through hole 22 communicated with the plug hole 21, specifically, the plug hole 21 penetrates through the axial member 2, and the seat body 1 is provided with a through hole 12 communicated with the plug hole 21, so that the pull nails 6 with different lengths can be inserted into the plug hole 21, but not limited thereto. The housing 3 is fixed on the seat body 1 and sleeved on the outer side of the axle center piece 2, the upper part of the housing 3 is provided with a bulge 311, and the seat body 1, the axle center piece 2 and the housing 3 enclose an installation space. The ball 5 is movably disposed in the through hole 22. The shaft sleeve 4 is arranged in the installation space and positioned above the air outlet end of the air hole 11, and the shaft sleeve 4 is sleeved outside the shaft core piece 2 in a manner of sliding up and down. The lower extreme of blind rivet 6 is pegged graft in jack 21, and the upper end of blind rivet 6 is pegged graft in general coupling assembling 7, and the bottom of general coupling assembling 7 is equipped with recess 721, and protruding 311 is connected with the recess 721 block, and the upper portion of general coupling assembling 7 is equipped with the installation station 711 that supplies the tool installation. The ball 5 is pushed against the ball 5 by the shaft sleeve 4, so that the ball 5 protrudes to the insertion hole 21 and clamps the rivet 6 in the insertion hole 21, thereby clamping and fixing the universal connection assembly 7 and the jig installed on the universal connection assembly 7, or the external air enters the air hole 11 to push the shaft sleeve 4 to slide upwards and release the ball 5, thereby unlocking the rivet 6, and enabling the rivet 6 and the universal connection assembly 7 to be quickly detached.

Referring to fig. 1 and fig. 2, in the present embodiment, the universal connecting assembly 7 includes a bottom plate 71 and a positioning plate 72, the positioning plate 72 is disposed below the bottom plate 71, the positioning plate 72 has an elastic structure, the upper end of the rivet 6 is inserted into the bottom plate 71, a groove 721 is disposed at the bottom of the positioning plate 72, the groove 721 is in interference fit with the protrusion 311, and the installation station 711 is disposed at the upper portion of the bottom plate 71. Because the positioning plate 72 has an elastic structure, the protrusion 311 on the upper portion of the housing 3 is engaged with the groove 721 of the positioning plate 72 to form an interference fit, and the positioning plate 72 naturally deforms upwards, so that the connection stability of the positioning plate 72 and the housing 3 is fully ensured. Specifically, the upper portion of the bottom plate 71 is provided with a positioning column 712 for positioning the jig.

Referring to fig. 3, a positioning block 31 is disposed on the upper portion of the housing 3, and a protrusion 311 is disposed on the positioning block 31. Specifically, the positioning blocks 31 are uniformly distributed on the housing 3 along the same circumferential direction. In the present embodiment, the number of the positioning blocks 31 is four, but not limited thereto.

Referring to fig. 5, a plurality of through holes 22 are distributed on the sidewall of the core member 2 along the circumferential direction of the core member 2, and each through hole 22 is provided with a ball 5. By providing a plurality of balls 5, the blind rivet 6 is clamped more firmly. The inner side of the sleeve 4 is provided with a slope 41 for pushing or releasing the ball 5. By driving the shaft sleeve 4 to slide upwards, the shaft sleeve 4 releases the balls 5 through the inclined surface 41 and no longer abuts against the balls 5, and by driving the shaft sleeve 4 to slide downwards, the shaft sleeve 4 abuts against the balls 5 through the inclined surface 41, so that the shaft sleeve 4 finally abuts against the balls 5 to extend out of the insertion holes 21. The inner side of the sleeve 4 may be provided with a chute having the inclined surface 41, but not limited thereto.

When an external air pump supplies air to the air hole 11, the air pushes the shaft sleeve 4 to slide upwards and compress the elastic piece 8. After the external air pump is disconnected to supply air to the air hole 11, the shaft sleeve 4 can slide downwards to reset under the action of the elastic restoring force of the elastic piece 8. But not limited to this, for example, the sleeve 4 may slide downward under its own weight. Wherein, the shaft sleeve 4 and the shell 3 can be provided with slot holes for the elastic pieces 8 to be inserted.

With reference to fig. 1 to 5, the general mounting base 100 for a pneumatic tool of the present invention has the following specific working principle:

air is supplied to the air hole 11 through an external air pump so as to push the shaft sleeve 4 to slide upwards and release the ball 5, the universal connecting assembly 7 is inserted into the insertion hole 21 of the shaft core piece 2 through the blind rivet 6, and the protrusion 311 on the shell 3 is clamped and connected with the groove 721 of the positioning piece 72 of the universal connecting assembly 7. Then the external air pump is disconnected to supply air to the air hole 11, the shaft sleeve 4 slides downwards under the action of the elastic restoring force of the elastic piece 8 and props against the ball 5 again, so that the ball 5 protrudes to the jack 21 and clamps the blind rivet 6, and the universal connecting assembly 7 is fixedly positioned and a jig arranged on the universal connecting assembly 7 is fixed.

In summary, the universal mounting base 100 for the pneumatic tooling of the present invention is provided with the universal connecting assembly 7 for mounting the fixture, and the universal connecting assembly 7 is connected in the axial core member 2 by the blind rivet 6, and the ball 5 is abutted by the shaft sleeve 4, so that the ball 5 protrudes to the insertion hole 21 and clamps the blind rivet 6 in the insertion hole 21, thereby fixing the universal connecting assembly 7; the blind rivet 6 can be released by the external air entering the air hole 11 to push the shaft sleeve 4 to slide upwards and release the ball 5, so that the blind rivet 6 and the universal connecting component 7 can be quickly detached; meanwhile, the shell 3 is also provided with a bulge 311 which is clamped with the groove 721 of the universal connecting component 7, so that the stability of the universal connecting component 7 arranged on the shell 3 is further ensured, and the shell 3 and the universal connecting component 7 are convenient to assemble and disassemble. Therefore, the universal mounting base 100 for the pneumatic tool is strong in universality and simple and convenient to operate.
