DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Embodiment 1

[0023] Reference Figure 1-Figure 3 A safety protection mechanism for a hydraulic breaker includes a hammer body 1. The outer walls on both sides of the hammer body 1 are connected to fixed blocks 4. The bottom of the hammer body 1 is connected to a connecting box 2. The bottom of the connecting box 2 is fixedly connected to a shell 3.

A nut 5 is fixedly connected to one side of the screw 6.

[0024] In the utility model, the buffer mechanism includes a sleeve box 7, the bottom of the fixed block 4 is fixedly connected to the sleeve box 7, the interior of the sleeve box 7 is fixedly connected to a top spring 10, one side of the top spring 10 is fixedly connected to a connecting block 8, one side of the connecting block 8 is fixedly connected to a connecting rod 9, the connecting rod 9 and the shell 3 are fixedly connected, the inner wall of the shell 3 is fixedly connected to a sound insulation pad 13, both sides of the sound insulation pad 13 are fixedly connected to two first main springs 14, and one side of the two first main springs 14 is fixedly connected to the same abutment plate 15.

[0025] In the utility model, a drill rod 11 is fixedly connected to one side of the bottom of the hammer body 1, a buffer frame 18 is connected to the inner side of the drill rod 11, elastic springs 16 are fixedly connected to both sides of the bottom of the shell 3, and one side of the two elastic springs 16 is fixedly connected to the same baffle 17.

[0026] In the utility model, both sides of the interior of the buffer frame 18 are fixedly connected with connecting blocks 19, and one side of two connecting blocks 19 among the multiple connecting blocks 19 is rotatably connected with a rotating rod 20, the connecting block 8 and the sleeve box 7 are slidably connected, one side of one connecting block 19 among the multiple connecting blocks 19 is rotatably connected with a stabilizing block, one side of the stabilizing block is fixedly connected with a secondary spring 22, and the secondary spring 22 and one side of the rotating rod 20 are fixedly connected with the same counterweight block 21.

[0027] In the utility model, when the device is used, the shell 3 contacts the ground, and the drill rod 11 impacts the ground. When the drill rod 11 impacts the ground, the hammer body 1 drives the sleeve box 7 at the bottom of the fixed block 4 on both sides to move due to the screw 6, and the sleeve box 7 is buffered by the internal top spring 10 and the connecting block 8, so as to protect it.
