[0029] The specific configuration and functions of the adjusting device 2 and the clamping device 3 are described in detail below.
[0030] Reference Figure 2 , Figure 3 and Figure 4As shown, in this embodiment: the adjustment device 2 includes a sliding rod 201, the sliding rod 201 is fixedly connected to the inner surface of the support frame body 1, the arc surface of the sliding rod 201 is slidably connected to two first support plates 202, the arc surface of the sliding rod 201 is slidably connected to two second support plates 203, the arc surface of the sliding rod 201 is slidably connected to two third support plates 204, the arc surface of the sliding rod 201 is slidably connected to two semicircular plates 205, one side of the first support plate 202 is fixedly connected to a first steel rope 206, one end of the first steel rope 206 away from the first support plate 202 is fixedly connected to the second support plate 203, the side of the second support plate 203 away from the first steel rope 206 is fixedly connected to a second steel rope 207, and the second steel rope 207 away from the second support plate 2 One end of 03 is fixedly connected to the third support plate 204, and the side of the third support plate 204 away from the second steel rope 207 is fixedly connected with the third steel rope 208, and the end of the third steel rope 208 away from the third support plate 204 is fixedly connected to the semicircular plate 205, and the lower surface of the semicircular plate 205 is fixedly connected with a sliding plate 209, and a support rod 210 is slidably inserted in the two sliding plates 209, and both ends of the support rod 210 are fixedly connected with a blocking plate 211, and the sides of the two sliding plates 209 close to each other are fixedly connected with a fixed plate 212, and a plug rod 213 is slidably inserted in the fixed plate 212. The arc surface of the support rod 210 is provided with a plurality of slots. When the staff has adjusted the support area of the support frame body 1, press the plug rod 213 to make the plug rod The limit plate 214 is pressed against the support rod 210 to prevent the sliding plate 209 from sliding on the support rod 210 due to external shaking during operation, thereby causing the semicircular plate 205 to deviate. One end of the rod 213 is fixedly connected to the limit plate 214, and the arc surface of the rod 213 is sleeved with a first spring 215. The two ends of the first spring 215 are respectively fixedly connected to the limit plate 214 and the fixed plate 212. When the staff releases the limit plate 214, the rebound force of the first spring 215 drives the limit plate 214 to move, and the limit plate 214 drives the rod 213 to slide in the fixed plate 212 until the rod 213 is inserted into the support rod 210. The first spring 215 improves the stability of the insertion rod 213 when limiting the sliding plate 209. The arc surface of the support rod 210 is sleeved with two second springs 216. The two ends of the second spring 216 are respectively fixedly connected to the sliding plate 209 and the blocking plate 211. When the staff releases the limit of the sliding plate 209 by the insertion rod 213, the rebound force of the second spring 216 drives the sliding plate 209 to slide on the arc surface of the support rod 210. At the same time, the sliding plate 209 drives the semicircular plate 205 to slide on the arc surface of the sliding rod 201. The semicircular plate 205 drives the third steel rope 208 to move.

[0031] Reference Figure 5 As shown, specifically, the clamping device 3 includes an L-shaped plate 31, which is fixedly connected to the upper surface of the support frame body 1, and a driving rod 32 is inserted into the internal thread of the L-shaped plate 31, and one end of the driving rod 32 is rotatably connected to a clamping ring 33, and a side of the clamping ring 33 away from the driving rod 32 is fixedly connected to an anti-skid pad 34, and the side of the anti-skid pad 34 away from the clamping ring 33 abuts against the support frame body 1, and an end of the driving rod 32 away from the clamping ring 33 is fixedly connected to a handle 35. When the staff has placed the platinum mesh, the handle 35 is turned, and the handle 35 drives the driving rod 32 to move in the internal thread of the L-shaped plate 31, and at the same time, the driving rod 32 drives the clamping ring 33 to move, and the clamping ring 33 drives the anti-skid pad 34 to move until the anti-skid pad 34 and the support frame body 1 are in contact. The anti-skid pad 34 is in contact with the support frame body 1 at this time, and the handle 35 is convenient for the staff to operate the device. The clamping ring 33 is fixedly connected to the side of the driving rod 32, and the arc surface of the positioning rod 36 is slidably connected to the L-shaped plate 31. When the staff turns the handle 35, the handle 35 drives the driving rod 32 to move in the inner thread of the L-shaped plate 31. At the same time, the driving rod 32 drives the clamping ring 33 to move, and the clamping ring 33 drives the positioning rod 36 to slide in the L-shaped plate 31. At this time, the positioning rod 36 limits the clamping ring 33 from rotating with the driving rod 32, so that the staff can quickly and accurately abut the anti-skid pad 34 against the surface of the support frame body 1.
[0032] Working principle: when the staff needs to increase the placement area on the support frame body 1, they pull the limit plate 214, and the limit plate 214 drives the insertion rod 213 to slide in the fixed plate 212, and the first spring 215 is stretched until the insertion rod 213 is disengaged from the slot of the support rod 210, and then the sliding plate 209 is pushed, and the two sliding plates 209 slide in opposite directions on the support rod 210, and the second spring 216 is compressed. At the same time, the sliding plate 209 drives the semicircular plate 205 to slide on the sliding rod 201, and the semicircular plate 205 drives the third steel rope 208 to move, and the third steel rope 208 drives the third support plate 204 to slide on the arc surface of the sliding rod 201, and the third support plate 204 drives the second steel rope 207 to move, and the second steel rope 207 drives the second support plate 203 to slide on the arc surface of the sliding rod 201 The second support plate 203 drives the first steel rope 206 to move, and the first steel rope 206 drives the first support plate 202 to slide on the arc surface of the sliding rod 201 until it is adjusted to a suitable position. At this time, the limit plate 214 is released, and the rebound force of the first spring 215 drives the limit plate 214 to move, and the limit plate 214 drives the insertion rod 213 to slide in the fixed plate 212 until the insertion rod 213 is inserted into the slot of the support rod 210. At this time, the support area of the support frame body 1 is adjusted, which avoids the different numbers of support points required for platinum meshes of different sizes when the staff needs to support platinum meshes of different sizes, resulting in the platinum mesh placed on the support frame body 1 being tilted, thereby causing the catalyst placed on the platinum mesh to spill, thereby improving the stability of the device.
[0033] When the staff needs to clamp the platinum mesh, the platinum mesh is placed on the support frame body 1 and the handle 35 is turned. The handle 35 drives the driving rod 32 to move in the inner thread of the L-shaped plate 31. At the same time, the driving rod 32 drives the clamping ring 33 to move. The clamping ring 33 drives the positioning rod 36 to slide in the L-shaped plate 31. At the same time, the clamping ring 33 drives the anti-skid pad 34 to move until the anti-skid pad 34 clamps the platinum mesh placed on the support frame body 1. At this time, the platinum mesh placed on the support frame body 1 is clamped, which avoids deformation of the platinum mesh during long-term work, resulting in insufficient combustion of the catalyst on the platinum mesh, thereby improving the practicability of the device.
