As a result, it is not easy to control the clamping force of the clamp during the clamping process, which can easily cause damage to the chip. Therefore, it is necessary to propose a flexible clamp for chip welding to solve the above-mentioned problems. Summary of the invention

[0006] An adjusting disk is arranged above the connecting plate, and the upper end surfaces of the connecting plate and the adjusting disk are penetrated with vertical corresponding guide holes, the two guide holes are slidably connected with sliding rods, the upper ends of the sliding rods are fixedly connected with a top plate, and a compression spring sleeved on the outer wall of the sliding rod is fixedly connected between the top plate and the adjusting disk, the lower end surface of the connecting plate is penetrated and threadedly connected with first screws located on the left and right sides of the guide holes, and the upper ends of the two first screws are fixedly connected with adjusting blocks abutting against the lower end of the adjusting disk.

[0007] In order to facilitate locking the position of the two vertical plates, as a preferred flexible clamp for chip welding of the utility model, the two locking mechanisms include support plates respectively fixedly connected to the opposite sides of the two vertical plates, the upper end surfaces of the two support plates are penetrated and threadedly connected with a second screw rod, and the lower ends of the two second screw rods are fixedly connected with an extrusion disk that is extruded with the upper end of the connecting plate.

[0008] In order to prevent the top plate from moving while improving the stability of the movement of the slide rod and the adjustment disk, a flexible clamp for chip welding is preferably used in the utility model. Limiting grooves are provided on the front and rear sides of the outer wall of the slide rod, and the front and rear sides of the inner walls of the two guide holes are fixedly connected with limit blocks extending into the interior of the two limit grooves and matching them.

[0009] In order to facilitate the separate rotation of the two second screws and the two first screws, and to achieve an anti-slip effect when turning the four knobs, a flexible clamp for chip welding is preferably used in the utility model. The other ends of the two second screws and the two first screws are fixedly connected with knobs, and the outer walls of the four knobs are provided with anti-slip patterns.

[0010] In order to prevent the slide bar from being separated from the inside of the two guide holes, as a preferred flexible clamp for chip welding of the utility model, the lower end of the slide bar is fixedly connected to a limiting plate.

[0012] In order to facilitate installation and fixation of the device to improve the stability of use, as a preferred flexible clamp for chip welding of the utility model, the lower end surface of the connecting plate is fixedly connected to two mounting frames.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] By making the two support blocks move relative to or away from each other and using two locking mechanisms to lock the positions of the two vertical plates, it is suitable for fixing chips of different sizes. The compression spring can be compressed while pushing the top plate downward, and the two sides of the chip enter the inside of the two notches respectively. The rebound force of the compression spring can then make the top plate move upward and squeeze the chip to fix it. When the fixation of the chip is too loose, by rotating the two first screws, the two adjustment blocks can be prompted to lift the adjustment disk upward and compress the compression spring until the chip is in a stable state. This flexible clamping and fixing method can further prevent the chip from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS
