A mounting plate 200 for positioning the storage plate 300 is fixedly arranged on the front of the sealing machine body 100. Two T-shaped pins 201 are symmetrically fixedly connected to the front of the sealing machine body 100. The top of the mounting plate 200 Two L-shaped through slots 202 are arranged at intervals, and one end of the bottom of the L-shaped through slot 202 is in the shape of a hook. The outer wall of the T-shaped pin 201 is movably connected to the L-shaped through slot 202. One end of the bottom of the L-shaped through slot 202 has an upward hook, which can be inserted into the outer wall of the T-shaped pin 201 through the port of the L-shaped through slot 202 of the mounting plate 200 and then moved so that the T-shaped pin 201 is located in the hook-shaped slot at one end of the bottom of the L-shaped through slot 202, so that the mounting plate 200 and the sealing machine body 100 can be kept relatively fixed, so that the disassembly and assembly of the mounting plate 200 on the sealing machine body 100 can be more convenient.

[0021] Furthermore, a vertically liftable T-shaped locking rod 301 is provided on the back of the mounting plate 200, and three linear through holes 203 are horizontally spaced apart on the front of the mounting plate 200. One end of the T-shaped locking rod 301 passes through the linear through hole 203 and extends to the position below the storage plate 300. Connecting rods 307 are fixedly connected to both sides of the front of the T-shaped locking rod 301. The connecting rods 307 pass through the linear through holes 203 and are fixedly connected to the back of the storage plate 300. The front end of the T-shaped locking rod 301 passes through the linear through holes 203 and is fixed to the bottom end of the storage plate 300. The storage plate 300 can be fixed on the mounting plate 200 by locking the position of the T-shaped locking rod 301 and the mounting plate 200.

[0022] At the same time, both ends of the T-shaped locking rod 301 are provided with retractable limiting rods 303, and a T-shaped through slot 302 connected to the three ends of the T-shaped locking rod 301 is opened inside the T-shaped locking rod 301, and the limiting rod 303 is movably inserted into the T-shaped through slot 302, and a round head rod 304 is movably provided in front of the T-shaped through slot 302. The round head of the round head rod 304 has a larger diameter and is thin on the left and thick on the right. The opposite ends of the two limiting rods 303 are rotatably connected with hinged connecting rods 306, and the ends of the two hinged connecting rods 306 are rotatably connected to the ends of the round head rod 304 respectively. The back side of the mounting plate 200 is fixedly connected with a positioning plate 204 The side wall of the positioning plate 204 is provided with a plurality of positioning grooves 205 from top to bottom, the limiting plug rod 303 is movably plugged into the positioning groove 205, one end of the T-shaped locking rod 301 extends to the bottom of the storage plate 300 and is fixedly connected to the bottom end of the storage plate 300, and the outer wall of the round head rod 304 is sleeved with an elastic compression spring 305, one end of the elastic compression spring 305 is fixedly connected to the end of the round head rod 304, and the other end of the elastic compression spring 305 is fixedly connected to the inner wall of the T-shaped through groove 302, and the elastic compression spring 305 is used for driving the round head rod 304 to translate and reset. When the round head rod 304 moves to the side away from the mounting plate 200, it drives the hinge connecting rod 306 to rotate and move, so that the hinge The connecting rod 306 pulls the limiting plug rod 303 into the T-shaped slot 302 of the T-shaped locking rod 301, so that the limiting plug rod 303 can be separated from the positioning slot 205 on the positioning plate 204, and the T-shaped locking rod 301 and the mounting plate 200 are unlocked, so that the T-shaped locking rod 301 can drive the storage plate 300 to move up and down. At this time, the elastic compression spring 305 is compressed and deformed, and has an elastic reaction force. After adjusting the height position, it is only necessary to cancel the pulling force on the round head rod 304 and use the elastic reverse thrust of the elastic compression spring 305 to make the round head rod 304 move back and reset, driving the end of the limiting plug rod 303 to move away from the T-shaped locking rod The end of 301 extends out and is inserted into the positioning groove 205 at the corresponding position of the side wall of the positioning plate 204 to achieve position locking; a push handle 308 that can be moved horizontally is provided at the bottom of the T-shaped locking rod 301, and a linear groove is provided at the bottom end of the T-shaped locking rod 301. The top of the push handle 308 passes through the linear groove and is fixedly connected to the other end of the round head rod 304. The push handle 308 is used to limit the driving of the insertion rod 303 to extend and retract at the end of the T-shaped locking rod 301. The setting of the push handle 308 cooperates with the corresponding linear groove on the T-shaped locking rod 301, which is convenient for the user to manually hold the push handle 308 to drive the round head rod 304 to move horizontally, thereby improving the convenience of operation.
