A connecting rod is rotatably connected to the other end of the clamping plate, and a sliding shaft seat is rotatably connected to the other end of the connecting rod. The sliding shaft seat is fitted onto the arc surface of the rotating shaft. A threaded hole is opened at the position corresponding to the slot on the sliding shaft seat, and a bolt is threaded to it.

[0019] The effect achieved by the above components is to facilitate the movement of the support plate using a handle.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, when a clamping device is needed for metal plate processing, pulling the handle moves the sliding shaft seat towards the end closer to the connecting rod. This movement stretches the first spring, which in turn expands the connecting rod to both sides, causing the first telescopic rod to extend. Once the desired position is reached, the bolt is rotated towards the center of the sliding shaft seat, pressing it against the anti-slip pad in the slot to secure it. At this point, the clamping bolt is rotated to loosen the baffle pressed against the clamping plate, allowing the metal plate to be placed inside. After placement, the clamping bolt is rotated to clamp the metal plate between the baffle and the clamping plate. Then, the positioning bolt fixed to the support plate is unscrewed, separating the positioning bolt from the support plate. The adjusting disc rotates, causing the rotating shaft to rotate. The rotating shaft rotates, causing the support rod and sliding shaft seat to rotate. The rotating sliding shaft seat rotates, causing the first spring to twist and the connecting rod to rotate. The rotating support rod rotates, causing the first telescopic rod and the fixed metal plate to rotate. After rotating to the required position, the positioning bolt is turned into the positioning hole on the support plate to fix the adjusting disc. After the metal plate is processed, the clamping bolt is turned out to loosen the baffle and remove the metal plate. After the metal plate is removed, the positioning bolt fixed on the support plate is turned out. After the positioning bolt is turned out, the first spring that twists rotates back, causing the rotating shaft to return to its original position. Then the bolt pressed against the anti-slip pad in the groove is loosened. The first spring that is stretched by the loosened bolt retracts, causing the sliding shaft seat to return to its original position, waiting for the next processing.

[0022] In this utility model, when a long metal plate needs to be processed and a lifting device is required, the handle fixed to one side of the support plate is pulled to move the support plate upward. The upward movement of the support plate causes the second spring and the second telescopic rod to stretch. After reaching the required position, the nut is turned in conjunction with the screw to fix the support plate on the column. After processing is completed and the nut in conjunction with the screw is loosened, the spring that has been stretched retracts and causes the support plate to return to its original position.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a multi-angle adjustable clamp bracket for metal plate processing, including a base 1, a lifting device 3 fixedly connected to the upper surface of the base 1, and a clamping device 2 provided inside the lifting device 3.

[0029] The specific configuration and function of its clamping device 2 and lifting device 3 will be described in detail below.

[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the clamping device 2 includes a support plate 201, which is fixedly connected to the lifting device 3. The support plate 201 has several positioning holes 213 and a through hole 219 at its center. A rotating shaft 218 is rotatably connected inside the through hole 219. A groove 203 is formed on the arc surface of the rotating shaft 218. Both ends of the rotating shaft 218 are fixedly connected to a support rod 207 and an adjusting disc 214, respectively. A first telescopic rod 208 is fixedly connected to both ends of the support rod 207. A clamping plate 209 is fixedly connected to the other end of the first telescopic rod 208. One end of the clamping plate 209 is threaded... Two clamping bolts 211 are connected, and a baffle 210 is threadedly connected to the arc surface of the clamping bolts 211. A connecting rod 212 is rotatably connected to the other end of the clamping plate 209, and a sliding bearing 205 is rotatably connected to the other end of the connecting rod 212. The sliding bearing 205 is sleeved on the arc surface of the rotating shaft 218. A threaded hole is opened at the corresponding position of the sliding bearing 205 and the slot 203, and a bolt 206 is threadedly connected thereto. An adjusting hole 216 is opened inside the adjusting plate 214, and a positioning bolt 215 is threadedly connected inside the adjusting hole 216. The positioning bolt 215 passes through the adjusting hole 216 and is threadedly connected to the positioning hole 213. The effect achieved by the above components is that the movement of the sliding bearing 205 is used to control the length of the first telescopic rod 208 to clamp metal plates of different sizes, and the rotating shaft 218 is rotated and fixed by the adjusting plate 214, the positioning hole 213, the adjusting hole 216, and the positioning bolt 215. A first spring 202 is fitted onto the arc surface of the rotating shaft 218. The two ends of the first spring 202 are fixedly connected to the sliding shaft seat 205 and the support plate 201, respectively. The purpose of these components is to allow the first spring 202 to quickly return the shaft to its original position after clamping. An anti-slip pad 204 is fixedly connected inside the slot 203. The surface of the anti-slip pad 204 has irregular textures. The purpose of these components is to increase friction using the anti-slip pad 204, facilitating the fixation of the sliding shaft seat 205. A handle 217 is fixedly connected to the arc surface of the sliding shaft seat 205, opposite to the bolt 206. The purpose of these components is to allow for rapid movement of the sliding shaft seat 205 using the handle 217.

[0031] Reference Figure 4As shown in this embodiment: a lifting device 3 is provided on the upper surface of the base 1. The lifting device 3 includes two columns 31. The lower surface of the columns 31 is fixedly connected to the base 1. A second telescopic rod 33 is fixedly connected inside the columns 31. A support plate 201 is fixedly connected to the output end of the second telescopic rod 33. Guide grooves 32 are provided on both sides of the columns 31. Screws 35 are slidably connected inside the guide grooves 32. The screws 35 pass through the guide grooves 32 and are threadedly connected to the other end of the support plate 201 with nuts 36. The effect achieved by the above components is to move and fix the support plate 201 using the second telescopic rod 33, screws 35, and nuts 36. A second spring 34 is sleeved on the outside of the second telescopic rod 33. The two ends of the second spring 34 are fixedly connected to the columns 31 and the support plate 201, respectively. The effect achieved by the above components is to allow the support plate 201 to quickly return to its original position using the second spring 34 after the metal plate is processed. A handle 37 is fixedly connected to one end of the support plate 201, and the handle 37 is inside the columns 31. The effect achieved by the above components is to facilitate the movement of the support plate 201 using the handle 37.

[0032] Working principle: When the metal plate processing requires the use of clamping device 2, pulling handle 217 moves the sliding shaft seat 205 closer to the end of connecting rod 212. This movement of the sliding shaft seat 205 towards the end of connecting rod 212 stretches the first spring 202, causing the connecting rod 212 to expand to both sides. This expansion of the connecting rod 212 then extends the first telescopic rod 208. Once the desired position is reached, rotate bolt 206 towards the center of the sliding shaft seat 205, pressing it against the anti-slip pad 204 in the slot 203 to fix the sliding shaft seat 205. At this time, rotating clamping bolt 211 loosens the baffle 210 pressed against clamping plate 209, allowing the metal plate to be placed in. After the metal plate is placed, rotating clamping bolt 211 clamps the metal plate between baffle 210 and clamping plate 209. Then, unscrew the positioning bolt 215 fixed to support plate 201. After the positioning bolt 215 separates from support plate 201, rotate to adjust... The adjustment disc 214 rotates, causing the rotating shaft 218 to rotate. The rotating shaft 218 rotates, causing the support rod 207 and the sliding shaft seat 205 to rotate. The rotating shaft seat 205 rotates, causing the first spring 202 to twist and the connecting rod 212 to rotate. The rotating support rod 207 rotates, causing the first telescopic rod 208 and the fixed metal plate to rotate. After rotating to the position required for processing, the positioning bolt 215 is turned into the positioning hole 213 on the support plate 201 to fix the adjustment disc 214. After the metal plate is processed, the clamping bolt 211 is turned out to loosen the baffle 210 and take out the metal plate. After the metal plate is taken out, the positioning bolt 215 fixed on the support plate 201 is turned out. After the positioning bolt 215 is turned out, the first spring 202 twists and rotates, causing the rotating shaft 218 to return to its original position. Then the bolt 206 pressed on the anti-slip pad 204 in the groove 203 is loosened. The bolt 206 loosens the stretched first spring 202 and retracts, causing the sliding shaft seat 205 to return to its original position, waiting for the next processing.

[0033] In this utility model, when a long metal plate needs to be processed and a lifting device 3 is required, the handle 37 fixed on one side of the support plate 201 is pulled to move the support plate 201 upward. The upward movement of the support plate 201 causes the second spring 34 and the second telescopic rod 33 to stretch. After reaching the required position, the nut 36 is rotated to cooperate with the screw 35 to fix the support plate 201 on the column 31. After the processing is completed and the nut 36 is loosened to cooperate with the screw 35, the stretched spring retracts and causes the support plate 201 to return to its original position.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
