The auxiliary nut 55 is also threadedly connected to the threaded rod 54; the slide rod 52 is slidably connected to the base 1; the limiting block 53 is located in the internal cavity of the base 1; the limiting block 53 can prevent the slide rod 52 from detaching from the base 1, thereby improving the stability of the overall structural design; the connecting cylinder 51 is provided with a first sliding groove; the side wall of the inner cavity of the base 1 is provided with a protrusion that cooperates with the first sliding groove; the side of the clamping seat 2 near the clamping plate 3 is provided with a baffle 21 for limiting the position of the metal workpiece, which facilitates the user to clamp the metal workpiece.

[0023] Adjustment assembly 6 includes a turntable 61, a slider 62 slidably connected to the turntable 61, a drive shaft 63 rotatably mounted on the base 1 and fixedly connected to the turntable 61, a main bevel gear 65 fixedly mounted at the end of the drive shaft 63, a secondary bevel gear 66 fixedly mounted at the end of the threaded rod 54, a ball-end rod 68 slidably mounted inside the drive shaft 63, a mounting plate 69 and a fixing rod 67 fixedly connected to the ball-end rod 68, an auxiliary ring 64 fixedly connected to the fixing rod 67, a slider 612 fixedly connected to the slider 62, a ball-end rod 611 fixedly connected to the slider 612, and a first spring whose two ends are fixedly connected to the mounting plate 69 and the drive shaft 63 respectively. 610, and a second spring 613 fixedly connected to the slider 612 and the turntable 61 at both ends respectively. The main bevel gear 65 and the secondary bevel gear 66 are both located in the cavity inside the base 1, and the main bevel gear 65 and the secondary bevel gear 66 are meshed and connected for transmission. The side of the auxiliary ring 64 is provided with friction texture to increase the friction between it and the base 1. The drive shaft 63 is provided with a second sliding groove for passing through both ends of the fixed rod 67. The slider 612 is provided with a T-shaped protrusion, and the slider 612 is slidably connected to the turntable 61 through the T-shaped protrusion. The establishment of the T-shaped protrusion can prevent the slider 612 from disengaging when sliding, so as to ensure the rationality of the overall structural design.

[0024] Working principle: When clamping a metal workpiece, the metal workpiece is placed on the side of the clamping seat 2 near the clamping plate 3, and the baffle 21 on the clamping seat 2 can prevent the metal workpiece from sliding off the clamping seat 2. Then, the clamping plate 3 is fixed to the base 1 by the fastening bolt 4, so that the metal workpiece can be clamped and fixed between the clamping plate 3 and the clamping seat 2. At this time, the corresponding processing steps can be performed on the metal workpiece.

[0025] Depending on the user's body size, if it is necessary to adjust the height of the clamp 2 or even the height of the metal workpiece held by the clamp 2, first push the slide button 62 to slide on the turntable 61. The slider 612 fixed on the slide button 62 slides synchronously, and the ball-end short rod 611 fixed on the other side of the slider 612 will no longer contact the ball end of the ball-end long rod 68. At this time, the ball-end long rod 68 is unrestricted, and the mounting plate 69 fixed on the ball-end long rod 68 is further connected to the drive shaft 63 by the first spring 610, so it slides within the drive shaft 63. Under the action of the first spring 610, the ball-head rod 68 of the part can slide towards the turntable 61. The auxiliary ring 64, which is fixedly connected to the ball-head rod 68 via the fixed rod 67, slides synchronously. At this time, a gap is generated between the auxiliary ring 64 and the base 1. Then, after the turntable 61 is rotated by the sliding button 62, the drive shaft 63, which is fixedly connected to the turntable 61, rotates synchronously inside the base 1. The main bevel gear 65 fixed at the end of the drive shaft 63 also interacts with the secondary bevel gear fixed at the end of the threaded rod 54. The gear 66 meshes and drives the transmission, causing the threaded rod 54 to rotate synchronously inside the base 1. Since the threaded rod 54, which is threadedly connected to the auxiliary nut 55, is fixed to the connecting cylinder 51, and the connecting cylinder 51 is fixedly connected to the clamp 2, and the clamp 2 is fixed with a sliding rod 52 that is slidably connected to the base 1, after the threaded rod 54 rotates, the connecting cylinder 51 will push the clamp 2 to slide up and down to meet the needs of users of different body sizes. Then, the sliding button 62 is released, connecting the slider 612 and the turntable 61 at both ends respectively. Under the action of the fixedly connected second spring 613, the slider 612 can be pushed to drive the ball head short rod 611 to slide towards the ball head long rod 68, thereby squeezing the ball head long rod 68, auxiliary ring 64 and fixed rod 67 to slide back, eliminating the gap between the auxiliary ring 64 and the base 1. At this time, the friction texture on the auxiliary ring 64 cooperates with the base 1 to generate a certain friction force to limit the rotation of the auxiliary ring 64, thereby limiting the rotation of the drive shaft 63 and other structures, locking the position of the clamp 2 and the metal workpiece clamped on the clamp 2.
