Description

Technical Field

[0001] This utility model relates to the field of clamping pliers technology, and in particular to a clamping pliers for screw installation. Background Technology

[0002] In the assembly of mechanical equipment, parts are usually connected by screws. In some confined spaces, screwdrivers cannot rotate the screws. Currently, needle-nose pliers are mainly used to clamp the screws and rotate them. However, due to the small contact area between the needle-nose pliers and the screw, slippage is likely to occur during the rotation process. This necessitates multiple clamping and rotations of the screw, resulting in low installation efficiency. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a screw clamp that can improve the screw installation efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides a screw clamp, comprising: clamping arms, two clamping arms hinged together, the clamping positions of the clamping arms having first clamping grooves, the first clamping grooves of the two clamping arms forming a first clamping space; a connector, the two clamping arms hinged together by the connector, the opposite sides of the two clamping arms having mounting grooves, the bottoms of the two mounting grooves abutting and being able to slide relative to each other, the connector passing through the two mounting grooves.

[0005] In one embodiment of the present invention, the first clamping groove is located on opposite sides of the two clamping arms, and the first clamping groove is arc-shaped.

[0006] In one embodiment of the present invention, the clamping arm includes a first link, a second link, and a third link, wherein the second link is located between the first link and the third link, and the first clamping groove is located on the third link.

[0007] In one embodiment of this utility model, the centerline of the first link is parallel to the centerline of the third link, and the angle between the centerline of the second link and the centerlines of the first link and the third link is an obtuse angle.

[0008] In one embodiment of this utility model, the length of the first link is greater than the length of the third link.

[0009] In one embodiment of the present invention, the mounting groove is located on the second connecting rod, and the connector passes through the second connecting rod of the two clamping arms.

[0010] In one embodiment of this utility model, the connector includes a connecting shaft and a limiting member. One end of the connecting shaft is provided with a baffle, and the connecting shaft is also provided with a slot. The limiting member engages with the slot, and the two clamping arms are located between the baffle and the limiting member. The baffle and the limiting member abut against the two clamping arms respectively.

[0011] In one embodiment of the present invention, a second clamping groove is provided on the clamping arm at the edge of the first clamping groove, and the maximum distance between the bottoms of the second clamping grooves on the two clamping arms is greater than the maximum distance between the bottoms of the first clamping grooves.

[0012] In one embodiment of the present invention, a third clamping groove is provided on the opposite side of the ends of the two clamping arms, and the two third clamping grooves constitute a second clamping space, wherein the center line of the first clamping space is perpendicular to the center line of the second clamping space.

[0013] In one embodiment of the present invention, the bottom of the first clamping groove is provided with anti-slip texture.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] This utility model discloses a screw-installing clamp, which, through the hinge of two clamping arms, allows the clamping arms to apply pressure to the screw to be installed.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figure 1 and Figure 2 As shown, the present invention discloses a screw clamping pliers, comprising: clamping arms 1, two clamping arms 1 hinged together, each clamping arm 1 having a first clamping groove 15 at its clamping position, the first clamping grooves 15 of the two clamping arms 1 forming a first clamping space; and a connecting member 2, the two clamping arms 1 hinged together, the two clamping arms 1 having mounting grooves 14 on opposite sides, the bottoms of the two mounting grooves 14 abutting each other and being able to slide relative to each other, the connecting member 2 passing through the two mounting grooves 14.

[0024] This embodiment provides a screw-installing clamp. The clamp is moved so that the screw to be installed is positioned within the first clamping space. The end of the clamping arm 1 furthest from the first clamping groove 15 is grasped, and both clamping arms 1 are rotated. This causes the first clamping grooves 15 of the two clamping arms 1 to move closer to each other until the bottoms of the two first clamping grooves 15 abut against the sidewall of the screw head. The clamping arms 1 apply pressure to the screw while simultaneously rotating it, thus completing the installation and tightening of the screw. The hinged connection of the two clamping arms 1 allows them to apply pressure to the screw. The first clamping groove 15 increases the contact area between the clamping arms 1 and the screw, increasing friction and preventing relative slippage during screw rotation. This allows for rapid screw tightening and improves installation efficiency. By providing mounting grooves 14 on opposite sides of the clamping arms 1, and having the bottoms of the mounting grooves 14 abutting each other and able to slide relative to each other, the overall thickness of the screw-installing clamp is reduced, making it suitable for use in narrow screw-installing spaces and improving the applicability of the screw-installing clamp.

[0025] The screw-installing clamp includes two symmetrically arranged clamping arms 1, which are hinged together, meaning they can rotate relative to each other. The clamping position of each clamping arm 1 is located near its end, and each clamping position has a first clamping groove 15. The first clamping grooves 15 of the two clamping arms 1 form a first clamping space for accommodating and clamping the screw to be installed. Specifically, each clamping arm 1 includes a first connecting rod 11, a second connecting rod 12, and a third connecting rod 13. The second connecting rod 12 is located between the first connecting rod 11 and the third connecting rod 13, meaning its two ends are connected to the ends of the first connecting rod 11 and the third connecting rod 13, respectively. The first clamping groove 15 is located on the third connecting rod 13. The first clamping groove 15 is located on the opposite side of the third link 13 on the two clamping arms 1. The first clamping groove 15 is arc-shaped. After the two third links 13 abut against each other, the first clamping space forms a column shape. The center line of the first clamping space is parallel to the hinge axis of the two clamping arms 1.

[0026] The centerline of the first link 11 is parallel to the centerline of the third link 13. The angles between the centerline of the second link 12 and the centerlines of the first and third links 11 are both obtuse angles. Specifically, the angle between the line connecting the centerlines of the second and third links 12 and the first and third links 13 is obtuse, and the angle between the line connecting the centerlines of the second and third links 12 and the third and third links 13 is also obtuse. This allows the two gripping arms 1 to form a clamp. The length of the first link 11 is greater than the length of the third link 13, and also greater than the combined length of the second and third links 12 and 13. This results in a longer overall length for the first link 11, which is used for manual gripping. The longer length of the first link 11 makes the screw-installing clamp suitable for deeper screw installation spaces, and also makes it easier for the manual gripping of the screws.

[0027] Reference Figure 3 As shown, two clamping arms 1 are hinged together by a connector 2. Mounting grooves 14 are provided on opposite sides of the two clamping arms 1. The bottoms of the two mounting grooves 14 abut against each other and can slide relative to each other. The connector 2 passes through the two mounting grooves 14. Specifically, the mounting grooves 14 are located on opposite sides of the two second connecting rods. The connector 2 passes through the second connecting rods 12 of the two clamping arms 1, and both clamping arms 1 are rotatably connected to the mounting grooves 14, allowing the two clamping arms 1 to rotate relative to each other. The mounting grooves 14 allow the two second connecting rods 12 to be stacked, reducing the overall thickness of the screw-installing clamps. This makes the screw-installing clamps suitable for use in narrower screw-installing spaces, increasing their applicability. The mounting grooves 14 also limit the maximum relative rotation angle of the two clamping arms 1, making the screw-installing clamps easier to use.

[0028] The connecting member 2 includes a connecting shaft 21 and a limiting member 24. The connecting shaft 21 is cylindrical, and one end of the connecting shaft 21 is provided with a baffle 22. The baffle 22 is circular, and its diameter is larger than that of the connecting shaft 21. The connecting shaft 21 is also provided with a retaining groove 23, which is arranged circumferentially along the connecting shaft 21 and located near the end of the connecting shaft 21 away from the baffle 22. The limiting member 24 can be regarded as a retaining spring. The limiting member 24 engages with the retaining groove 23, and its diameter is larger than that of the connecting shaft 21. The connecting shaft 21 passes through the two second connecting rods 12 and also passes through the two mounting slots 14. The two clamping arms 1 are located between the baffle 22 and the limiting member 24. The baffle 22 and the limiting member 24 abut against the outer sides of the two clamping arms 1 respectively, so that the bottoms of the two mounting slots 14 abut against each other. When the two clamping arms 1 rotate relative to each other, the bottoms of the two mounting slots 14 can slide relative to each other. Through the setting of the connecting member 2, the two clamping arms 1 can be prevented from disengaging from the connecting shaft 21 or from being misaligned.

[0029] Preferably, an elastic element is provided between the two first connecting rods 11. The elastic element can be regarded as a spring. After the two clamping arms 1 are rotated, the pressure applied to the clamping arms 1 stops, and the elastic element can drive the two clamping arms 1 to reset.

[0030] Reference Figure 4 As shown, preferably, a second clamping groove 16 is provided on one side of the clamping arm 1 and at the edge of the first clamping groove 15. The maximum distance between the bottoms of the second clamping grooves 16 on the two clamping arms 1 is greater than the maximum distance between the bottoms of the first clamping grooves 15. That is, the second clamping groove 16 can clamp a larger number of screws to be installed than the first clamping groove 15 can clamp. The thickness of the first clamping groove 15 is the same as that of the third link 13, and the thickness of the second clamping groove 16 is less than that of the third link 13. Specifically, the thickness of the second clamping groove 16 is half the thickness of the third link 13, so that the screw installation clamping pliers can clamp screws of different diameters to be installed. In another embodiment, the clamping arm 1 is provided with a second clamping groove 16 on both sides, and the curvature of the two second clamping grooves 16 and the first clamping groove 15 is different. The thickness of the two second clamping grooves 16 and the first clamping groove 15 is one-third of the thickness of the third connecting rod 13, so that the screw installation clamping pliers can clamp screws of more diameters to be installed, thus improving the applicability of the screw installation clamping pliers to a wider range.

[0031] Preferably, a third clamping groove 17 is provided on the opposite side of the ends of the two clamping arms 1. The two third clamping grooves 17 form a second clamping space for clamping the screw to be installed. When the two third connecting rods 13 abut against each other, the second clamping space forms a column shape, and the center line of the first clamping space is perpendicular to the center line of the second clamping space. That is, the center line of the first clamping space is parallel to the axis of the connecting shaft 21, and the center line of the second clamping space is perpendicular to the axis of the connecting shaft 21. By setting the third clamping groove 17, the screw installation clamp can be extended vertically into the screw installation space to install the screw. By setting the first clamping groove 15, the screw installation clamp can be extended horizontally into the screw installation space to install the screw, thereby improving the applicability of the screw installation clamp.

[0032] Preferably, the bottom of the first clamping groove 15, the second clamping groove 16 and the third clamping groove 17 are all provided with anti-slip texture, thereby increasing the friction of the clamping arm 1 when clamping the screw to be installed and preventing the clamping groove from sliding relative to the screw to be installed.

[0033] In use, move the screw installation clamp to position the screw to be installed in the first clamping space, grasp the end of the clamping arm 1 away from the first clamping groove 15, rotate the two clamping arms 1 to move the first clamping grooves 15 of the two clamping arms 1 toward each other until the bottom of the two first clamping grooves 15 abuts against the side wall of the screw head on the screw to be installed. While the clamping arms 1 apply pressure to the screw to be installed, they drive the screw to be installed to rotate, thereby completing the installation and locking of the screw to be installed.

[0034] This embodiment of a screw-installing clamp utilizes a hinged design of two clamping arms 1. The clamping arms 1 apply pressure to the screw to be installed. The first clamping groove 15 increases the contact area between the clamping arms 1 and the screw, thereby increasing friction and preventing relative slippage during screw rotation. This allows for quick screw tightening and improves installation efficiency. Furthermore, the clamping arms 14 have mounting grooves 14 on opposite sides, with their bottoms abutting and sliding relative to each other. This reduces the overall thickness of the clamp, making it suitable for use in confined screw installation spaces and expanding its applicability.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
