The control hole 911, the adjusting lever 55, the plug section 551 and the transmission groove 631 are all of a quadrangular prism shape.
One of the insertion sections 551 is forcibly pulled in a direction approaching the first rod body 21, and both the insertion section 551 and the corresponding adjustment lever 55 are moved in a direction away from the control hole 911 until the insertion section 551 is inserted into the corresponding transmission groove 631. The rotation of the first shaft 11 or the third shaft 11 can then be adjusted by turning the end of the control lever 91 away from the first lever body 21 by means of a tool. The lever 91 may be turned by a wrench or pliers or the like.
Referring to fig. 1, 2 and 4, when one of the insertion sections 551 is inserted into the corresponding transmission slot 631, the link member 2 is in a vertically downward state, and at this time, the height of the hammer 3 is adjusted, so as to better compare the distance between the hammer 3 and the riser that needs to be knocked.
The implementation principle of the breaking hammer for removing the riser is as follows: the height of the ram 3 is optionally fine-tuned or tuned as desired, and then one of the socket segments 551 is pulled in a direction approaching the first shaft body 21. Until the socket segment 551 is socket with the corresponding driving slot 631. In the process that the inserting section 551 is inserted into the corresponding transmission groove 631, the inserting section 551 pushes one of the tips 831 to be separated from the transmission groove 631, and the movement of one tip 831 drives the tip 831 on the other rack 83 to move through the limiting gear 82, so that both the tips 831 are separated from transmission, and both the first connecting shaft 63 and the third connecting shaft 72 can rotate.
Then, by means of the tool rotating the control rod 91, the control rod 91 rotates to drive the adjusting rod 55 and the inserting section 551 to rotate, and the inserting section 551 rotates to drive the first connecting shaft 63 or the third connecting shaft 72 to rotate, so that the first gear 61 and the second gear 62 can be driven to rotate, and then the transmission rod 221 and the second rod body 22 are driven to lift through the convex teeth 222, and the second rod body 22 can be driven to lift to drive the hammer body 3 to lift.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
