[0027] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0028] In order to solve the technical problems in the background technology, such as Figure 1-3 As shown, the present application provides a technical solution: a metal screw clamp, the characteristics of which are as follows:

[0029] The workbench 1 is a long, rectangular table of a certain height, with a long, through-hole 2 on its surface. The through-hole 2 is designed to facilitate the passage of bolts or other fasteners, thereby facilitating the fixing of the fixture. A movable limit block 3 is provided on the workbench 1 and is positioned at a predetermined position on the workbench 1. The limit block 3 has a long, convex groove 4, the shape of which matches the groove 9 on the first and second sliders 5, 6. Specifically, the length of the groove 4 is the sum of the lengths of the grooves 9 on the first and second sliders 5, 6, respectively. The first and second sliders 5, 6 are symmetrically arranged on the workbench 1. Each of the first and second sliders 5, 6 has a first inclined surface 7 at its top, a straight line 8 in the middle, and a groove 9 at its end. The groove 9 matches the groove 4 on the limit block 3, allowing both sliders 5 and 6 to slide along the groove 4, thereby adjusting their positions. Arc-shaped grooves 10 are provided on two adjacent surfaces of the first and second sliders 5, 6, and are arranged in pairs. The arcuate grooves 10 on the first and second sliders 5 and 6 form a retractable discharge hole 11, facilitating the placement and removal of the metal screw. The ends of the first and second sliders 5 and 6 are also provided with second inclined surfaces 12, parallel to the first inclined surface 7. Protrusions 13 are also provided on the workbench 1, abutting the first and second inclined surfaces 7 and 12. This design facilitates smooth sliding of the first and second sliders 5 and 6 when they are pushed by the stop block 3. This helps ensure smooth movement and improved guidance during movement, allowing the discharge hole 11 to open and close. An eccentric wheel 14 is mounted on the workbench 1, its outer surface abutting the stop block 3. A handle 15 is provided around the eccentric wheel 14. By pulling the handle 15, the user rotates the eccentric wheel 14, causing it to move about its axis, thereby driving the stop block 3 to reciprocate along a direction parallel to the axis of symmetry of the first and second sliders 5 and 6. Such a design makes it easy for the user to adjust the positions of the first slider 5 and the second slider 6 to achieve clamping of the screw.

[0030] During implementation, the multiple protrusions 13 are all cylindrical, with their side surfaces in contact with the first and second inclined surfaces 7 and 12, i.e., their unfolded surfaces are rectangular. This design shifts the contact between the protrusions 13 and the first and second inclined surfaces 7 and 12 from surface contact to line contact, reducing friction, improving the efficiency of the mechanism, and reducing wear.

[0031] Furthermore, the protrusion 13 is a roller. The outer surface of the roller abuts against the first inclined surface 7 and the second inclined surface 12, so that the roller can roll along the first inclined surface 7 and the second inclined surface 12. Specifically, the roller is a cylindrical component with a smooth outer surface to reduce frictional resistance during rolling. During implementation, when the first slider 5 and the second slider 6 are pushed by the limit block 3, the roller rolls along the first inclined surface 7 and the second inclined surface 12. The roller changes the friction between the protrusion 13 and the first inclined surface 7 and the second inclined surface 12 from sliding friction to rolling friction, thereby reducing friction and improving the efficiency of the mechanism.

[0032] It should be noted that, as shown in the figure, the mounting holes 16 are provided on two adjacent surfaces of the first slider 5 and the second slider 6, and the two mounting holes 16 are connected. The mounting hole 16 is circular in shape, and its diameter and depth are determined by the diameter and length of the spring 17. The spring 17 is used to adjust the distance between the first slider 5 and the second slider 6. In this embodiment, the spring 17 is made of stainless steel and has good elasticity and corrosion resistance. The diameter of the spring 17 ensures that it can be installed in the mounting hole 16; the length of the spring 17 ensures that when installed in the mounting hole 16, the first slider 5 and the second slider 6 have opposite thrusts. When the first slider 5 and the second slider 6 are pushed apart a certain distance, the screw can be taken out of the discharge hole 11.

[0033] Furthermore, the mounting holes 16 are located at both ends of the adjacent surfaces of the first slider 5 and the second slider 6. That is, four mounting holes 16 are provided, one at the head and one at the end of the two adjacent surfaces. And because they are provided on two adjacent surfaces, the mounting holes 16 located at the two head ends form a pair, and the mounting holes 16 at the two end ends form a pair, forming a through hole. The design of the mounting holes 16 allows the spring 17 to be installed therein, thereby providing the necessary elastic force. The spring 17 is provided in the mounting hole 16 to provide elastic force, so that the head and end ends of the first slider 5 and the second slider 6 are subjected to force simultaneously and move simultaneously, thus being more stable.

[0034] It should be noted that the balls 18 are spherical and evenly distributed within the grooves 9. The diameter of the balls 18 is slightly smaller than the width of the grooves 9, allowing the balls 18 to roll freely within the grooves 9, enabling relative movement between the protruding grooves 4 and the grooves 9. During the relative movement between the protruding grooves 4 and the grooves 9, the balls 18 provide support and lubrication, reducing internal friction and improving operating efficiency.

[0035] Furthermore, the limiting plate 19 is fixedly provided on the workbench body 1, located at both ends of the limiting block 3, and is used to limit the movement of the limiting block 3 in the direction of the limiting plate 19. The limiting plate 19 is made of high-strength stainless steel material and has good wear resistance and corrosion resistance. The limiting plate 19 is fixedly provided on the workbench body 1, and its two ends are respectively located at both ends of the limiting block 3. The limiting plate 19 is in the shape of a long strip, and its length is greater than the sum of the width of the limiting block 3 and its movement mileage. When the limiting block 3 is moving, due to the limiting effect of the limiting plate 19, the limiting block 3 cannot continue to move in the direction of the limiting plate 19, thereby ensuring that the limiting block 3 can only move along the symmetry axis of the first slider 5 and the second slider 6.

[0036] It should be noted that the concave arc groove 20 is concave, and its shape is adapted to the protrusion 13 so as to accommodate the protrusion 13. When the protrusion 13 enters the concave arc groove 20, the concave arc groove 20 provides a retreat space, so that the distance between the first slider 5 and the second slider 6 reaches the maximum. At this time, the discharge hole 11 is fully opened, making it easy to remove the clamped screw.

[0037] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
