DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides the following technical solutions: a clamp for mechanical manufacturing, comprising a U-shaped plate 1, wherein the front and rear sides of the U-shaped plate 1 are rotatably mounted with mounting shafts 3, the surface of the mounting shaft 3 is fixedly mounted with a first clamping arm 4 and a second clamping arm 8, the first clamping arm 4 and the second clamping arm 8 are provided with a sliding groove 18, a threaded rod 13 is threadedly mounted on the middle thread of the U-shaped plate 1, a moving block 9 is rotatably mounted on one end of the threaded rod 13, a movable shaft 17 is fixedly mounted on the front and rear ends of the moving block 9, and the movable shaft 17 is slidably connected with the inside of the sliding groove 18, a first mounting block 5 is mounted on the right side of the moving block 9, a second mounting block 6 is mounted on one end of the first clamping arm 4 and the second clamping arm 8, a screw rod 11 is threadedly mounted on the internal thread of the first mounting block 5 and the second mounting block 6, and a movable knob 7 is fixedly mounted on one end of the screw rod 11.

[0021] The screw rod 11 can be driven to rotate by the movable knob 7. Since the threaded rod 11 is threadedly connected to the first mounting block 5 or the second mounting block 6, when the screw rod 11 rotates, the position of the screw rod 11 can be moved to clamp parts of different sizes. The threaded rod 13 can be driven to rotate by the connecting rod 15. Since the threaded rod 13 is threadedly connected to the U-shaped plate 1, when the threaded rod 13 rotates, the moving block 9 can be driven to move. Since the movable shaft 17 is internally slidably connected to the sliding groove 18, the first clamping arm 4 and the second clamping arm 8 can be driven to open or close when the moving block 9 moves. When the moving block 9 moves to the right, the first clamping arm 4 and the second clamping arm 8 will be closed. Conversely, when the moving block 9 moves to the left, the first clamping arm 4 and the second clamping arm 8 will be opened, thereby facilitating the clamping and fixing of parts of different sizes. The provision of the mounting screw 10 can facilitate the installation and fixing of the second mounting block 6. Similarly, by unscrewing the mounting screw 10, the second mounting block 6 can also be easily disassembled, thereby increasing the installation and disassembly of the device. Flexibility, and the movable knob 7 and the screw rod 11 are arranged in multiple groups in an upper and lower pair, so that the parts can be clamped and fixed more firmly and reliably, which increases the practicality of the device. The setting of the mounting ball 2 can avoid the installation and fixation of the connecting rod 15, and the setting of the connecting rod 15 can facilitate the user to drive the threaded rod 13 to rotate through the connecting rod 15. The multiple anti-slip grooves 16 are arranged in a circle on the surface of the connecting rod 15, which can increase the friction force on the surface of the connecting rod 5, so that when the user holds the connecting rod 15 to drive the threaded rod 13 to rotate, it is not easy to slip, which is conducive to improving the convenience of using the device. The setting of the mounting plate 12 and the mounting hole 14 can facilitate the installation and fixation of the U-shaped plate 1, which is conducive to the installation and fixation of the device. The anti-rust paint coating set on the surface of the U-shaped plate 1, the first clamping arm 4, the first mounting block 5, the second mounting block 6, the second clamping arm 8, the movable block 9 and the mounting plate 12 can make the device less prone to rust, which is conducive to extending the service life of the device.

[0022] In one aspect of the present embodiment, the setting of the mounting ball 2 can avoid the connection rod 15 from being installed and fixed, and the setting of the connection rod 15 can facilitate the user to drive the threaded rod 13 to rotate through the connection rod 15. The multiple anti-slip grooves 16 are arranged in a circle on the surface of the connection rod 15, which can increase the friction force on the surface of the connection rod 5, so that when the user holds the connection rod 15 to drive the threaded rod 13 to rotate, it is less likely to have a hand slip problem, which is conducive to improving the convenience of using the device.

[0023] In one aspect of the present embodiment, the provision of the mounting screws 10 can facilitate the installation and fixation of the second mounting block 6. Similarly, by unscrewing the mounting screws 10, the second mounting block 6 can also be easily disassembled, thereby increasing the flexibility of the device for installation and disassembly. The movable knobs 7 and the screw rods 11 are provided in multiple groups in an upper and lower manner, so that the parts can be clamped and fixed more firmly and reliably, thereby increasing the practicality of the device.

[0024] In one aspect of the present embodiment, the provision of the mounting plate 12 and the mounting hole 14 can facilitate the installation and fixation of the U-shaped plate 1, which is beneficial to the installation and fixation of the device, and the anti-rust paint coating provided on the surface of the U-shaped plate 1, the first clamping arm 4, the first mounting block 5, the second mounting block 6, the second clamping arm 8, the moving block 9 and the mounting plate 12 can make the device less prone to rust, which is beneficial to extending the service life of the device.
