When specific implementation, the lower end of drive shaft 31 is fixed with the blade group axle 21 fixed connection through screw, to form an integral, this connection mode facilitates the dismounting when the inside part of the blade group axle 21 is damaged or drive shaft 31 is damaged. The linkage assembly 3 still includes elastic telescopic mechanism 32 and the push limit mechanism 33.

[0031] As described above, when specific implementation, the utility model discloses a convenient dismounting's blade head structure of wall breaking machine through setting the linkage assembly 3 in the inside of the blade group axle 21, so that user can drive elastic telescopic mechanism 32, push limit mechanism 33 action through drive shaft 31, compared with prior art can more easily, quickly dismount the blade group 2. The setting of push limit mechanism 33 makes the blade group 2 and fixed seat 1 whether in the process of dismounting or when installing and fixing good use, the whole blade group 2 is more stable. Specifically, through the mutual cooperation of the structure between the drive shaft 31 in the blade group axle 21, the push block 332 and the annular groove 333 of fixed seat 1 makes the connection between the blade group axle 21 and fixed seat 1 more closely, stably, not easy to sway when installing the blade group 2, so as not to easily lead to the friction wear and tear of the blade group axle 21 and fixed seat 1, prolongs the service life of the blade group 2, simultaneously, the dismounting of the blade group 2 is more convenient, fast.

[0032] As Figures 1-5As shown, in specific implementation, the elastic expansion mechanism 32 includes a spring 321 arranged inside the cutter group shaft 21 for driving the push limiting mechanism 33 to act so as to disassemble the cutter group 2, a limiting space 322 formed between the driving shaft 31 and the cutter group shaft 21 for mounting the spring 321 so as to facilitate the expansion of the spring 321, the limiting space 322 including a first limiting part 3221 arranged on the driving shaft 31 and a second limiting part 3222 arranged on the cutter group shaft 21. That is, the spring 321 is arranged between the first limiting part 3221 and the second limiting part 3222 and elastically expands and contracts between the first limiting part 3221 and the second limiting part 3222.

[0033] As shown in the drawings, Figures 1-8 As shown, in specific implementation, the push limiting mechanism 33 includes a push block 332 arranged on the cutter group shaft 21 through a rotating shaft 331. In specific implementation, the rotating shaft 331 is fixedly arranged on the cutter group shaft 21, and the push block 332 is sleeved on the rotating shaft 331 and can rotate around the rotating shaft 331. The push limiting mechanism 33 further includes an annular groove 333 arranged on the fixed seat 1 for limiting cooperation with the push block 332, and a limiting end 334 arranged on the driving shaft 31 for limiting cooperation with the push block 332. In the normal state of the cutter group 2 after being installed, the upper end of the push block 332 is clamped into the annular groove 333, thereby blocking and limiting the cutter group 2. When the cutter group 2 needs to be disassembled, the user drives the spring 321 to contract by pressing down the driving shaft 31, the limiting end 334 at the lower end of the driving shaft 31 drives the push block 332 to rotate around the rotating shaft 331, and the upper end of the push block 332 gradually exits the annular groove 333. Under the tension of the spring 321, the user can easily lift the cutter group shaft 21 upward to pull out the cutter group 2, and this design is simple in structure and convenient and fast to operate.

The arrangement of the shaft seal 41 and the shaft seal gasket 42 facilitates the sealing of the fixed seat shell 11 and the linkage shaft 12, and plays a waterproof and leakproof effect. The arrangement of the shaft seal gasket 42 positions the shaft seal 41, limiting the retreat or displacement of the shaft seal 41 to affect the sealing effect. The arrangement of the first bearing 43, the bearing sleeve 44 and the second bearing 45 facilitates the rotation of the linkage shaft 12 relative to the fixed seat shell 11.

[0038] As shown in Figures 1-10 , the present application also provides a wall breaking machine, which comprises a convenient disassembly and assembly blade head structure of the wall breaking machine described in the present application. In specific implementation, the fixed seat 1 can be detachably connected to the metal disc 100 at the lower end of the cup body of the wall breaking machine or integrally formed with the metal disc 100. Specifically, when the fixed seat 1 is detachably connected to the metal disc 100, the fixed seat 1 or the internal bearing assembly 4 can be conveniently repaired and replaced when damaged, which can effectively save costs. When the fixed seat 1 is integrally formed with the metal disc 100, the production cost is relatively low, and the sealing performance is better. The user can select a suitable way to set the fixed seat 1 in the wall breaking machine according to the needs.

[0039] The specific disassembly and assembly process and principle of the wall breaking machine blade head structure of the present application are as follows:

[0040] When the knife group 2 needs to be disassembled for replacement or cleaning, the user presses down the pressing part 311 of the driving shaft 31 with the thumb, the driving spring 321 contracts, the limiting end 334 at the lower end of the driving shaft 31 drives the rotating block 332 to rotate around the rotating shaft 331, at this time the second annular protrusion 3342 abuts against the third hooking part 33231, and with the gradual pressing down of the driving shaft 31, the first hooking part 33221 gradually exits the annular groove 333. Under the tension of the spring 321, the user can easily complete the disassembly of the knife group 2 by clamping the gripping part 211 with two fingers and lifting it upward.

[0041] When the knife set 2 needs to be installed, similarly, the user holds the handle 211 with two fingers, and presses the pressing part 311 of the driving shaft 31 with the thumb, the driving spring 321 is retracted, the limiting end 334 of the lower end of the driving shaft 31 drives the rotating block 332 to rotate around the rotating shaft 331, and as the driving shaft 31 is gradually pressed down, the first hooking part 33221 is clamped in the annular groove 333, at this time the second hooking part 33222 abuts against the upper end of the first annular protrusion 3341, and the third hooking part 33231 is hooked at the lower end of the second annular protrusion 3342, thus completing the installation.
