[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model discloses a clamp 100, including a left clamping arm 10, a right clamping arm 20, and an elastic element 30. The left clamping arm 10 is pivotally mounted on the right clamping arm 20, and the left clamping arm 10 and the right clamping arm 20 constitute a clamping mouth 40. The elastic element 30 has a base 31 and elastic arms 32 located on both sides of the base 31. A receiving groove 51 for accommodating the elastic arm 32 is provided on the side of the left clamping arm 10 and the right clamping arm 20 away from the clamping mouth 40. The receiving groove 51 has a positioning groove 52 that mates with the elastic arm 32 to fix the elastic arm 32 within the receiving groove 51. This configuration allows the elastic element 30 to be fixed without reducing the width of the receiving groove 51, and also facilitates the installation of the elastic element 30 within the receiving groove 51.

[0024] Compared to existing technologies, the clamp 100 of this invention, by providing a positioning groove 52 within the receiving groove 51 that cooperates with the elastic element 30, can fix the elastic element 30 without reducing the width of the receiving groove 51, thereby effectively preventing the elastic element 30 from shaking within the receiving groove 51. Simultaneously, since there is no need to reduce the width of the receiving groove 51, the elastic element 30 can be easily installed within the receiving groove 51 without adversely affecting the assembly efficiency of the clamp 100.

[0025] Preferably, please refer to Figure 5As shown, the receiving groove 51 includes a bottom wall 511 and side walls 512 located on both sides of the bottom wall 511. The positioning groove 52 includes a first positioning groove 521, which is disposed on the bottom wall 511. The elastic arm 32 includes a first positioning part 321. The first positioning part 321 cooperates with the first positioning groove 521 to fix the elastic arm 32 in the receiving groove 51, thereby effectively preventing the elastic arm 32 from shaking in the receiving groove 51, and thus effectively improving the stability of the clamping force of the clamp 100.

[0026] Preferably, please refer to Figure 5 As shown, the receiving groove 51 further includes a groove front wall 513 located between the two groove side walls 512. The positioning groove 52 includes a second positioning groove 522, which is disposed on the groove front wall 513. The elastic arm 32 further includes a second positioning part 322 that cooperates with the second positioning groove 522. Through the cooperation of the second positioning part 322 and the second positioning groove 522, it can be further ensured that the elastic element 30 is fixedly installed in the receiving groove 51, and the elastic arm 32 is effectively prevented from shaking in the receiving groove 51, thereby effectively improving the stability of the clamping force of the clamp 100.

[0027] Preferably, the first positioning groove 521 and the second positioning groove 522 form an included angle, which is an obtuse angle. This arrangement allows the elastic arm 32 of the elastic element 30 to be smoothly inserted into the receiving groove 51, facilitating assembly. Simultaneously, because the first positioning groove 521 and the second positioning groove 522 form an included angle, they define a plane. This plane, in conjunction with the first positioning part 321 and the second positioning part 322, effectively fixes the elastic arm 32 of the elastic element 30 within the positioning groove 52, thereby effectively preventing the elastic element 30 from wobbling within the receiving groove 51 and thus effectively improving the stability of the clamping force of the clamp 100.

[0028] Preferably, please refer to Figure 2 , Figure 3 as well as Figure 4 As shown, both the left clamping arm 10 and the right clamping arm 20 include a main body 61, a pivot portion 62 located on one side of the main body 61, and a clamping portion 63 located on the other side of the main body 61. The receiving groove 51 is disposed on the main body 61.

[0029] Preferably, at least one of the left clamping arm 10 and the right clamping arm 20 is provided with a drain hole to facilitate the discharge of the metal surface treatment liquid from the groove of the clamp 100. Simultaneously, any metal surface treatment liquid remaining in the groove of the clamp 100 can be easily rinsed away, thereby effectively reducing the corrosion of the clamp 100 by the metal surface treatment liquid, extending the service life of the clamp 100, saving production costs, and protecting the environment.

[0030] Preferably, please refer to Figure 2 , Figure 3 as well as Figure 5 As shown, the drain hole includes a first drain hole 71. The first drain hole 71 communicates with the receiving tank 51 in the thickness direction of the main body 61. This arrangement allows for easy drainage of the metal surface treatment liquid stored in the receiving tank 51, and also facilitates rinsing away the metal surface treatment liquid located in the receiving tank 51.

[0031] Preferably, the first drain hole 71 is disposed on the side wall 512 of the tank and penetrates the side wall 512 to communicate with the receiving tank 51. Further, both side walls 512 of the receiving tank 51 are provided with the first drain hole 71. The projections of the first drain holes 71 on the two side walls 512 onto a plane perpendicular to the thickness direction of the side wall 512 at least partially overlap. This arrangement facilitates the rapid drainage of the metal surface treatment liquid contained in the receiving tank 51. Simultaneously, this arrangement also makes it easier to rinse away the metal surface treatment liquid from the receiving tank 51.

[0032] Preferably, the main body 61 is provided with a supporting arm 611. The supporting arm 611 of the left clamping arm 10 cooperates with the supporting arm 611 of the right clamping arm 20 to limit the minimum opening angle of the clamp 100. The drain hole further includes a second drain hole 72. At least one of the supporting arms 611 of the left clamping arm 10 and the right clamping arm 20 is provided with the second drain hole 72. This arrangement facilitates the rapid discharge of the metal surface treatment liquid from the clamp 100 in the direction perpendicular to the thickness of the left clamping arm 10 and the right clamping arm 20, and also facilitates rinsing away the metal surface treatment liquid.

[0033] Preferably, please refer to Figure 4 As shown, the left clamping arm 10 has a left half-groove 721 on its supporting arm 611, and the right clamping arm 20 has a right half-groove 722 on its supporting arm 611. The left half-groove 721 and the right half-groove 722 together form the second drain hole 72. At this time, the second drain hole 72 is located in the middle of the supporting arms 611 of the left clamping arm 10 and the right clamping arm 20, thereby allowing for rapid drainage of the metal surface treatment liquid.

[0034] Preferably, please refer to 2. Figure 3 as well as Figure 4 As shown, the main body 61 is also provided with an operating groove 612. The operating groove 612 is used to cooperate with a clamping device to open the clamp 100. The clamping device can be a manual clamping device or a pneumatic clamping device. The second drain hole 72 passes through the supporting arm 611 of the left clamping arm 10 or the supporting arm 611 of the right clamping arm 20 and is connected to the operating groove 612. This arrangement allows for the rapid discharge of the metal surface treatment liquid located in the operating groove 612. At the same time, it also makes it easy to rinse away any residual metal surface treatment liquid in the operating groove 612.

[0035] Further, please refer to Figure 1 , Figure 2 as well as Figure 3 As shown, the clamping portions 63 of the left clamping arm 10 and the right clamping arm 20 together constitute the clamping nozzle 40. The second drain hole 72 is connected to the clamping nozzle 40. This arrangement allows the metal surface treatment liquid stored in the operating tank 612 to be quickly discharged through the clamping nozzle 40.
