[0028] Reference Figure 2 and Figure 3The supporting device 4 includes a cylinder 401, which is slidably sleeved on the surface of the connecting rod 2. A groove 402 is opened on the surface of the connecting rod 2. A round rod 403 is fixedly connected to the inner wall of the groove 402. A supporting rod 404 is rotatably sleeved on the surface of the round rod 403. When using the supporting device 4, the cylinder 401 is manually controlled to slide to a suitable position on the connecting rod 2, and then the supporting rod 404 is manually controlled to rotate on the surface of the round rod 403, so that the inner wall of one side of the groove 402 clamps the supporting rod 404, thereby making the supporting rod 404 and the connecting rod 2 perpendicular to each other, and the supporting rod 404 is placed on the chrome-plated barrel. The top of the cylinder 401 is fixedly connected to the top of the cylinder 401, so that the connecting rod 2 is vertically inserted into the interior of the chrome-plating barrel, so that the metal product clamped by the clamping plate 6 can be immersed in the chrome-plating liquid without touching the inner wall of the chrome-plating barrel. The top of the cylinder 401 is fixedly connected to the ring 409, and the ring 409 is sleeved on the surface of the connecting rod 2. A bolt 410 is inserted through a thread on one side of the ring 409.

When using the connecting device 5, the connecting rod 2 is manually inserted into the interior of the fixed cylinder 501, and then the connecting frame 1 and the connecting rod 2 are connected together. The reverse operation can separate the connecting rod 2 and the connecting frame 1, and then the clamp head can be replaced. Because the threaded rod 3 may slip when the clamp is used multiple times, which may cause the clamping plate 6 to fail to clamp the metal product well. In this way, the service life of the clamp can be extended by replacing the clamp head, which reduces the waste of resources to a certain extent.

[0030] Working principle, when using the chrome plating clamp, manually rotate the threaded rod 3, because the direction of the thread on the surface of the threaded rod 3 is opposite from the middle to both sides, so that the clamping plate 6 clamps the metal product to be chrome-plated, and then hold the connecting rod 2, and then completely immerse the metal product clamped by the clamp head in the chrome plating liquid in the chrome plating barrel, so that the metal product can be chrome-plated well. When using the supporting device 4, manually control the cylinder 401 to slide to the appropriate position on the connecting rod 2, and then manually rotate the bolt 410, so that the bolt 410 is squeezed on the surface of the connecting rod 2, so that the cylinder 401 is well fixed on the connecting rod 2, and then manually control the extension rod 405 to slide out of the support rod 404, so that After the fixing rod 406 passes through one side of the extension rod 405, it is inserted into the small hole 407. The top of the fixing rod 406 is pulled toward the extension rod 405 by the first spring 408, so that the fixing rod 406 is well restricted inside the small hole 407, and the support rod 404 is well fixed on the surface of the extension rod 405, so that the length of the support rod 404 can be extended, so that the support rod 404 can be placed on chrome-plated barrels of different models, and then the support rod 404 is manually controlled to rotate on the surface of the round rod 403, so that the inner wall of one side of the groove 402 clamps the support rod 404, so that the support rod 404 and the connecting rod 2 are perpendicular to each other, and the support rod 404 is placed on the top of the chrome-plated barrel. The connecting rod 2 is vertically inserted into the chrome-plating barrel, so that the metal product clamped by the clamping plate 6 can be immersed in the chrome-plating liquid without contacting the inner wall of the chrome-plating barrel. When the supporting device 4 is not in use, the elastic band 412 is pulled to move the arc block 411 on the surface of the cylinder 401, so that the arc block 411 is set on one side of the supporting rod 404, so that the supporting rod 404 is well clamped in the groove 402. When the connecting device 5 is used, the connecting rod 2 is manually inserted into the interior of the fixed cylinder 501, and the limiting ring 502 is manually rotated to control the clamping rod 504 to pass through the L-shaped plate 503, and then the clamping rod 504 is inserted into the first clamping hole 506, and then the connecting device 5 is used. The locking rod 504 is inserted into the second locking hole 507, which can well fix the connecting rod 2 inside the fixing tube 501. The locking rod 504 is pulled in the direction close to the L-shaped plate 503 by the second spring 505, and then the locking rod 504 is well restricted to the inside of the second locking hole 507, thereby connecting the connecting frame 1 and the connecting rod 2 together. The reverse operation can separate the connecting rod 2 and the connecting frame 1, and then the clamp head can be replaced. Because the threaded rod 3 may slip when the clamp is used multiple times, which will cause the clamping plate 6 to fail to clamp the metal product well. In this way, the service life of the clamp can be extended by replacing the clamp head, which reduces the waste of resources to a certain extent.
