[0018] the following will clearly and completely describe the technical scheme in the embodiment of the utility model in combination with the attached drawings in the embodiment of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the art without making creative work belong to the protection scope of the utility model.
[0019] referring to figure 1-3, a Fume Extractor Arm includes heating furnace 1. Both sides of the bottom of heating furnace 1 are fixedly connected with cushion blocks 16, and the bottom of cushion blocks 16 is provided with anti-skid lines. By setting cushion blocks 16, the friction between the bottom of heating furnace 1 and the ground can be increased to prevent abnormal movement of heating furnace 1. The top on the left side of heating furnace 1 is connected with interface 2, and the top and bottom on the left side of interface 2 are provided with positioning slots 3, The left side of the heating furnace 1 and the top and bottom of the interface 2 are fixedly connected with the shell 4, the inner side of the inner wall of the shell 4 is fixedly connected with the bearing 5, the inner side of the bearing 5 is fixedly connected with the screw 6, the end of the screw 6 away from the bearing 5 penetrates to the outside of the shell 4, and the rotary table 17 is fixedly connected with the screw 6. By setting the rotary table 17, the contact area between the user's hand and the screw 6 can be increased, It is convenient for the user to rotate the screw 6 through the turntable 17. The surface of the screw 6 is threaded with a screw sleeve 7, the right side of the screw sleeve 7 is fixedly connected with a lifting plate 8, the right side of the lifting plate 8 is fixedly connected with a slider 18, the right side of the inner wall of the shell 4 is provided with a chute 19, and the slider 18 is sliding connected with the chute 19. By setting the slider 18 and the chute 19, the lifting stability of the lifting plate 8 can be increased and the tilt of the lifting plate 8 can be prevented, The inner side of the lifting plate 8 is fixedly connected with a spring 9, the end of the spring 9 away from the lifting plate 8 is fixedly connected with the inner wall of the housing 4, the left side of the screw sleeve 7 is fixedly connected with a connecting rod 10, the left end of the connecting rod 10 penetrates to the outside of the housing 4 and is fixedly connected with a vertical plate 11, which is located at the rear side of the trapezoidal block 14, the surface of the transmission rod 12 is in contact with the left side of the trapezoidal block 14, the front side of the vertical plate 11 is fixedly connected with a transmission rod 12, and the left side of the interface 2 is provided with an, The right side of the gas gathering hood 13 is fixedly connected with a sealing ring 20, and the right side of the sealing ring 20 is in contact with the left side of the interface 2. By setting the sealing ring 20, the tightness of the gas gathering hood 13 and the interface 2 can be increased, and smoke can be prevented from leaking between the gas gathering hood 13 and the interface 2. The top and bottom of the gas gathering hood 13 are fixedly connected with a trapezoidal block 14 used in conjunction with the transmission rod 12, and the right side of the trapezoidal block 14 is fixedly connected with a positioning rod 15, The right end of the positioning rod 15 extends to the inside of the positioning groove 3. By setting the heating furnace 1, the interface 2, the positioning groove 3, the shell 4, the bearing 5, the screw 6, the screw sleeve 7, the lifting plate 8, the spring 9, the connecting rod 10, the vertical plate 11, the transmission rod 12, the gas collecting cover 13, the trapezoidal block 14 and the positioning rod 15, the problem that the existing gas collecting cover is not convenient for users to connect is solved. The smoke side suction gas collecting cover in the furnace has the advantage of convenient connection of the gas collecting cover, It saves users a lot of time and improves the practicability of the heating furnace.
[0020] when in use, the operator drives the screw 6 to rotate inside the bearing 5 through the turntable 17. The rotation of
[0021] to sum up, the smoke side suction gas collecting hood in the furnace solves the problem that the existing gas collecting hood is not convenient for users to connect by setting heating furnace 1, interface 2, positioning groove 3, housing 4, bearing 5, screw 6, screw sleeve 7, lifting plate 8, spring 9, connecting rod 10, vertical plate 11, transmission rod 12, gas collecting hood 13, trapezoidal block 14 and positioning rod 15.
[0022] it should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "include", or any other variation thereof are intended to cover non exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent in such a process, method, article, or device.
[0023] although the embodiments of the utility model have been shown and described, for those skilled in the art, it can be understood that these embodiments can be changed, modified, replaced and modified without departing from the principle and spirit of the utility model. The scope of the utility model is limited by the appended claims and their equivalents.
