DETAILED DESCRIPTION
[0017] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:
[0018] like Figure 1 — Figure 4 As shown, a marking device for a replaceable powder box includes a shell 1, a wire drum 2 is installed in the shell 1, a wire 3 is wound on the wire drum 2, and a powder box 4 is also included. A powder box cover 5 is fixed to the bottom of the powder box 4, and a sealing film 51 is provided at the bottom of the powder box cover 5. The rear end of the shell 1 has a mounting groove 1.1, and a powder box seat 6 is fixed to the bottom of the mounting groove 1.1. The wire 3 passes through the powder box seat 6. The powder box cover 5 is detachably connected to the powder box seat 6. A serrated insert 7 for scratching the sealing film 51 is provided on the top of the powder box seat 6. A spring sheet 8 is fixed to the top of the shell 1, and the spring sheet 8 is clamped with the top of the powder box 4. The rear end of the shell 1 has a hole for the wire 3 to pass through.
[0019] like Figure 2 As shown, in order to facilitate the disassembly and assembly of the powder box 4, the left and right ends of the bottom of the powder box cover 5 have slide grooves 52 extending forward and backward, and the left and right ends of the top of the powder box seat 6 have L-shaped sliders 61 extending forward and backward, and the L-shaped sliders 61 are inserted into the slide grooves 52.
[0020] like Figure 1 , Figure 3 As shown, the rear end of the spring sheet 8 has a buckle 81, and the top of the powder box 4 has a slot 41, and the buckle 81 is inserted into the slot 41. The spring sheet 8 can press the powder box 4 to improve the installation stability of the powder box 4.
[0021] like Figure 1 As shown, in order to facilitate pinching the powder box 4, a protrusion 42 is protruded on the left and right outer walls of the powder box 4.
[0022] like Figure 3 and Figure 4 As shown, in order to facilitate powder adding, the rear end of the powder box 4 has a powder adding hole 43, which is connected to the inside of the powder box 4, and a powder box plug 9 for blocking the powder adding hole 43 is installed at the rear end of the powder box 4. A waist-shaped protrusion 44 is convexly provided at the rear end of the powder box 4, and the rear end of the powder box plug 9 has a waist hole 91, through which the waist-shaped protrusion 44 passes, and the front end of the powder box plug 9 has a plug 92, which is inserted into the powder adding hole 43.
