The impact head 9 is movably connected with a connecting piece 10 used for connecting an external vent pipe, and a vent groove is formed in the connecting piece 10 in the direction perpendicular to the axis of the impact rod 7. One side fixedly connected with that connecting piece 10 kept away from impact bar 7 wholly is columniform intake pipe 11, intake pipe 11 and air channel intercommunication, and columniform butt piece 12 has been cup jointed to the week side of intake pipe 11, and the pass protrusion of intake pipe 11 is on the surface of butt piece 12, and the pass department of intake pipe 11 is equipped with the chamfer. One side of the connecting piece 10 close to the impact head 9 is provided with a cylindrical connecting groove 13, and the connecting groove 13 is arc-shaped concave. The impact head 9 is embedded in the connecting groove 13, the end face of one end of the impact head 9 embedded in the connecting groove 13 is in an arc-shaped convex shape, and a floating cavity 14 for the relative floating of the impact head 9 in the connecting groove 13 is reserved between the connecting groove 13 and the impact head 9. The outer side wall of the connecting groove 13 is in threaded connection with a fixing ring 15 which is cylindrical in whole, and the fixing ring 15 is used for limiting the position of the impact head 9 in the connecting groove 13. The outer side wall of the fixing ring 15 is provided with a second guide surface 22 facilitating rotation of the fixing ring 15.

The fixing ring 15 is far away from one side of the connecting piece 10 and is provided with an arc-shaped limiting groove 17 on the inner side wall close to the impact rod 7, and the number of the limiting grooves 17 is preferably two and is symmetrical by taking the central axis of the fixing ring 15 as a symmetry line. A cylindrical bolt hole 18 penetrating through the impact rod 7 is formed in the position, corresponding to the limiting groove 17, of the impact rod 7, and the axial direction of the bolt hole 18 is perpendicular to the axial direction of the impact rod 7. A bolt piece 19 matched with the bolt hole 18 is inserted in the bolt hole 18, and two end parts of the bolt piece 19 protrude out of the bolt hole 18 and are embedded in the limiting groove 17 to limit the impact rod 7 to rotate relative to the fixing ring 15, so that the connecting piece 10 is not easy to rotate relative to the impact rod 7.

The periphery of the impact rod 7 is sleeved with an elastic piece 16, and the elastic piece 16 is a rectangular spring. The elastic component 16 is located between the fixing ring 15 and the fixing seat 8, and two ends of the elastic component 16 respectively abut against one side face of the fixing ring 15 close to the fixing seat 8 and one side face of the fixing seat 8 close to the fixing ring 15.

The implementation principle of the embodiment is as follows: when the installation, fix connecting seat 6 on platform 5 earlier to place fixing base 8 on connecting seat 6, then peg graft the dwang in rotating hole 20, in 7 spiral entering connecting seat 6 and fixing base 8 of impact rod. Then the elastic piece 16 is sleeved on the impact rod 7, the bolt piece 19 is inserted into the bolt hole 18, then the bolt piece 19 is placed in the limiting groove 17 on the fixing ring 15, then the connecting groove 13 on the connecting piece 10 is buckled on the impact head 9, and at the moment, the connecting piece 10 is rotated to enable the fixing ring 15 to be in threaded connection with the connecting piece 10. Wherein, first spigot surface 21 has increased the frictional force on the surface of fixing base 8 and has conveniently fixed fixing base 8, and second spigot surface 22 has increased the frictional force on the fixed ring 15 surface and has conveniently fixed ring 15. When the striking rod 7 is loosened, the rotating rod is inserted into the gap of the elastic member 16 and inserted into the rotating hole 20 to fasten the striking rod 7. In the course of the work, the cylinder 2 moves, and the telescopic link 202 stretches out the cylinder body 201 under the guide effect of guide bar 4, and telescopic link 202 drives the direction that the cylinder body 201 was kept away from to the floating joint orientation and removes, because the angular deviation of 2 installations of cylinder can lead to intake pipe 11 and air inlet department to have the deviation. If the intake pipe 11 is misaligned when it contacts the intake port, a gap is formed between the contact block 12 and the peripheral side of the intake port, that is, the contact block 12 is inclined. Due to the presence of the elastic member 16, the elastic member 16 on the side where the abutment block 12 is inclined is compressed and largely deformed. At this time, due to the floating chamber 14, when the elastic member 16 releases the elastic potential energy of the connecting member 10, the groove bottom of the arc-shaped connecting groove 13 abuts against the arc-shaped impact head 9, and the circumferential side of the connecting member 10 is subjected to different acting forces of the elastic member 16, so that the connecting member 10 can be angularly adjusted with respect to the impact head 9. That is, the connecting member 10 floats at the impact head 9 until the plane of the abutting block 12 close to the air inlet is attached to the peripheral side of the air inlet, and at this time, the air inlet pipe 11 is aligned with the air inlet, and at this time, the connecting member 10 does not float any more. The accuracy with which the intake pipe 11 is aligned with the intake port is improved. In addition, because the elastic member 16 is a rectangular spring, when the rectangular spring is compressed, the adjacent spring rings are in surface contact when in contact, so that the pressure applied to the rectangular spring is reduced, and the service life of the rectangular spring is prolonged. Moreover, the contact surfaces of the rectangular spring and the fixed ring 15 and the fixed seat 8 are also in surface contact, so that the pressure of the elastic piece 16 borne by the fixed ring 15 and the fixed seat 8 is reduced, and the service life of the fixed ring 15 and the fixed seat 8 is prolonged.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
