[0037] Specifically, the electric surgical pen for smoking that is easy to disassemble and assemble provided by the embodiment of the utility model adopts a method of splicing the first shell 100 and the second shell 100 together, so that the shell 100 of the electric surgical pen can be easily disassembled when needed, so as to perform maintenance on the inside of the electric surgical pen. By providing two first ridges 111 on the first shell 110 and corresponding two first slots 121 on the second shell 120, the first shell 110 and the second shell 120 can be spliced ​​together through the cooperation of the first ridges 111 and the first slots 121. Before splicing, the electric knife assembly is installed in the first shell 110. After splicing, one end of the outer shell 100 used to operate the electrode 410 is inserted into the smoke hood 200, and the smoke hood 200 and the outer shell 100 are fixed by a connecting structure, so that the first shell 110 and the second shell 120 cannot be separated. The other end of the outer shell 100 is connected to the smoke guide pipe 300 to complete the installation of the electric knife pen. If the electric knife pen needs to be disassembled, it is only necessary to remove the smoke guide pipe 300, and then release the connecting structure to remove the smoke hood 200, so that the first shell 110 and the second shell 120 can be separated. The structure is simple, the operation is convenient, and it is easy to maintain and process, which reduces the production cost.

[0038] Further, see Figure 4According to some embodiments of the utility model, a first annular groove 130 is provided on the outer peripheral wall of one end of the shell 100 close to the smoke hood 200, and a second annular groove 131 is circumferentially provided in the middle part of the bottom wall of the first annular groove 130. The connecting structure includes a first convex ring 210 provided on the inner peripheral wall of the smoke hood 200, and the end of the smoke hood 200 is sleeved in the first annular groove 130. The end face of the smoke hood 200 abuts against the side wall of the first annular groove 130, and the first convex ring 210 is stuck in the second annular groove 131.

[0039] Specifically, the outer peripheral walls at the same end of the first shell 110 and the second shell 120 are both provided with annular grooves of corresponding shapes and positions. After the two are assembled together through the cooperation of the first convex strip 111 and the first slot 121, the two annular grooves can be assembled to form a first annular groove 130. The second annular groove 131 is constructed in the same way as the first annular groove 130. The end of the smoke hood 200 provided with the first convex ring 210 is inserted into the first annular groove 130 until the end face of the smoke hood 200 abuts against the side wall of the first annular groove 130, which can play a limiting role. At this time, the first convex ring 210 can just be snapped into the second annular groove 131, thereby realizing the fixed connection between the smoke hood 200 and the outer shell 100, so that the first shell 110 and the second shell 120 are not easily separated. When disassembly is required, the smoke hood 200 can be pulled out with force. The structure is simple and the operation is convenient.

[0040] Furthermore, according to some embodiments of the present invention, the smoke hood 200 is elastic, and the outer diameter of the first annular groove 130 is smaller than the inner diameter of the smoke hood 200, so that when the smoke hood 200 is sleeved in the first annular groove 130, the outer shell 100 can squeeze the smoke hood 200 outward, so that the smoke hood 200 is more securely connected and the possibility of the smoke hood 200 being detached is reduced.

[0041] Reference Figures 5 to 8 According to the utility model, a smoking electric knife pen that is easy to disassemble and assemble also includes a connecting head 140, and the connecting head 140 is provided with a through hole 141.
