The position where the lever end 931 and the pressing end 932 connect is screwed into the outer cover 92, and a locking interface 933 is reserved at the position where the lever end 931 and the pressing end 932 connect. A V-shaped beryllium copper sheet A94 is installed on the upper wall of the pressing end 932. The V-shaped beryllium copper sheet A94 is in close contact with the inner surface of the top of the outer cover 92. The pressing end 932 is away from the lever end 931. A bent end A934 is installed at the bottom of one side. A wedge block 95 is screwed into the outer cover 92. A protruding end A951 that cooperates with the bent end A934 is installed at the top of the wedge block 95. A protruding end B952 that is fastened to the latch 91 is installed at the bottom of the wedge block 95. The bottom of the rotating bar 96 is screwed into the outer cover 92. A bent end B961 that cooperates with the locking interface 933 is installed at the top of the rotating bar 96. A wedge end 962 facing the wedge block 95 is installed in the center of the rotating bar 96. The extrusion wall B964 of the rotating bar 96 that is farther away from the wedge block 95 is in close contact with the V-shaped beryllium copper sheet B97 installed on the side wall of the outer cover 92.

[0041] Reference Figures 8-11 The outer cover 92 is equipped with a pin 925, a rotating column 926 and a round opening A927. The wedge block 95 has a pre-reserved round opening D955.

[0043] Reference Figures 4-7 and Figure 8The bottom of the wedge block 95 has a pre-reserved skewed extrusion wall A953. The extrusion wall A953 and the protrusion B952 form a fastening interface for the latch rod 91 to engage. The latch rod 91 and the extrusion wall A953 press against each other to make the wedge block 95 rotate. During the rotation of the wedge block 95, the latch rod 91 moves along the extrusion wall A953 into the fastening interface or moves out of the fastening interface, thereby achieving the stopping and disassembly of the wedge block 95 and the latch rod 91.

[0044] Reference Figure 5 and Figure 8 An arched wall 956 is installed between the protruding ends A951 and B952 on the wedge block 95. During disassembly, the bent end A934 on the stop bar 93 and the wedge end 962 on the rotating bar 96 are in contact with the arched wall 956. As the wedge block 95 rotates in the opposite direction, the arched wall 956 can compress the wedge end 962 to move, and then compress the rotating bar 96 to rotate, and separate the bent end B961 on the rotating bar 96 from the locking interface 933. When the wedge block 95 rotates to the extreme point where it forms the widest gap with the side wall of the outer cover 92, the V-shaped beryllium copper sheet B97 presses down on the rotating bar 96, and the wedge end 962 in the middle of the rotating bar 96 presses down on the side of the arched wall 956 near the protruding end B952, thus achieving the purpose of stopping.

[0045] Reference Figure 7 , Figure 8 and Figure 11 The bottom of the protrusion B952 on the wedge block 95 has a pre-reserved inclined wall 9521. The bottom of the rotating bar 96 is equipped with an inner wall 963 on the side farther from the extrusion wall B964. After disassembly, the inclined wall 9521 is rotated to the side of the inner wall 963 to prevent obstruction and also to help constrain the wedge block 95.

[0046] The width of the protrusion B952 on the wedge block 95 is matched with the width of the inner side of the buckle 91 to prevent the buckle 91 from moving after it is engaged with the wedge block 95, thus ensuring the stability after assembly.

[0047] Reference Figures 4-9 One side of the wedge block 95 has a pre-reserved round opening C954, and the top of one side of the outer cover 92 has a pre-reserved assembly opening A928. The bottom of the elastic element 98 is installed on the round opening C954 on the wedge block 95, and the top of the elastic element 98 is installed on the assembly opening A928 on the outer cover 92.

[0048] Reference Figure 12 The V-shaped beryllium copper sheet A94 has a "V" shaped structure. One side of the V-shaped beryllium copper sheet A94 has a pre-reserved assembly port B942, which is used to cooperate with the tensioning screw to be fixed to the pressing end 932 on the stop bar 93. The other side of the V-shaped beryllium copper sheet A94 has a pressing end A941, which is in close contact with the inner surface of the top of the outer cover 92 to achieve the purpose of pressing the V-shaped beryllium copper sheet A94.

[0049] Reference Figure 13 The V-shaped beryllium copper sheet B97 has a "V" shaped structure. One side of the V-shaped beryllium copper sheet B97 has a pre-reserved assembly port C972, which is used to cooperate with the tensioning screw to be fixed to the side wall inside the outer cover 92. The other side of the V-shaped beryllium copper sheet B97 has a pressing end B971, which is in close contact with the extrusion wall B964 on the rotating bar 96 to achieve the purpose of pressing the V-shaped beryllium copper sheet B97.

[0050] Reference Figure 2 One side of the outer cover 92 is fixed to the assembly block 921. The two ends of the buckle 91 are screwed to the concave seat 911, which is fixed to one side. The upper end of the concave seat 911 is fixed to the stop block. The surface of the buckle 91 is in close contact with the inner side of the concave seat 911. When the buckle 91 is engaged with the wedge block 95, the end of the buckle 91 abuts against the stop block. One side of the concave seat 911 is fixed to the vertical plate 912. Several sets of concave seats 911 are provided on the vertical plate 912. Each set of concave seats 911 is equipped with a buckle 91. The other side of the concave seat 911 is in contact with the outer wall of the outer cover 92 to prevent the buckle 91 from moving after it is engaged with the wedge block 95.

[0051] Reference Figure 1 and Figure 2 Additionally, it should be noted that the lower end of the vertical plate 912 on the connector 9 on the support plate A7 is detachably connected to the end of the baffle plate 5, and the mounting block 921 on it is fixedly connected to the support plate A7.

[0052] The lower end of the vertical plate 912 on the connector 9 on the support plate B8 is detachably connected to the powder feeding nozzle 6, and the assembly block 921 on it is fixedly connected to the support plate B8.

[0053] The specific implementation method is as follows: In use, first move the lever end 931 on the stop bar 93 to ensure that the wedge block 95 forms the widest gap between itself and the edge of the outer cover 92 with the cooperation of the elastic member 98. At this time, it is in the disassembled state. Press the baffle plate 5 and the support plate A7 and the powder feeding nozzle 6 and the support plate B8 respectively, so that the latch 91 and the extrusion wall A953 on the wedge block 95 are in contact and the wedge block 95 is pressed to rotate. During the rotation, the latch 91 moves along the extrusion wall A953 to the connection between the extrusion wall A953 and the protrusion B952. The mouth, thereby achieving the purpose of engaging the protruding end B952 and the latching rod 91, and then securing the baffle plate 5 with the support plate A7 and the powder feeding nozzle 6 with the support plate B8. With the cooperation of the V-shaped beryllium copper sheet A94, the pressing end 932 on the baffle 93 rotates to allow the bent end A934 at the bottom to engage with the protruding end A951 on the wedge block 95, achieving the purpose of stopping. With the V-shaped beryllium copper sheet A94 in a compressed state, it can ensure that the baffle 93 and the wedge block 95 are always engaged with the latching rod 91 without being subjected to external force.

[0054] When disassembling the baffle plate 5 and support plate A7, and the powder feeding nozzle 6 and support plate B8, the stop bar 93 is moved. The stop bar 93 rotates, causing the locking interface 933 and the bent end B961 at the top of the rotating bar 96 to engage, achieving a tight fit. The V-shaped beryllium copper sheet B97 remains compressed, ensuring that the rotating bar 96 stops the stop bar 93 without external force. The bent end A934 on the stop bar 93 separates from the protruding end A951 on the wedge block 95, thus releasing the stop bar 93 from stopping the wedge block 95. At this moment, the latch 91 pulls the wedge block 95 to rotate in the opposite direction via the protruding end B952. The arched wall 956 on the wedge block 95 first contacts the wedge end 962 on the rotating bar 96, and then the latch 91 pulls the wedge block 95 to rotate, accompanied by the wedge... As block 95 rotates, the arched wall 956 on wedge block 95 presses against the wedge end 962, causing it to move. This, in turn, presses against the rotating strip 96, causing it to rotate in the forward direction. This separates the bent end B961 from the locking interface 933 on the stop strip 93. At this moment, as wedge block 95 rotates to a certain point, the bent end A934 on the stop strip 93 and the protruding end A951 on wedge block 95 are no longer in place. They can only be in close contact with the arched wall 956 on wedge block 95. Wedge block 95 then rotates until the protruding end B952 separates from the latch 91. After wedge block 95 and latch 91 separate, with the cooperation of elastic element 98, it rotates to the extreme point where the widest gap is formed between it and the side wall of outer cover 92. At this moment, the purpose of complete disassembly is achieved, thereby achieving the purpose of disassembling the baffle plate 5 from the support plate A7 and the powder feeding nozzle 6 from the support plate B8.

[0055] When it is necessary to adjust the height of the baffle plate 5 or the powder feeding nozzle 6, simply select the appropriate latch 91 and follow the above steps to assemble and disassemble. It is very convenient to use.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
