[0025] 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. Example 1

[0026] Reference Figure 1-3 As shown, the elastic buckle for the clamp of this utility model includes: a buckle body 21, which is used to press against one end face of the clamp; an embedded copper nut 22, which is installed on the buckle body 21; a spring 23, which is sleeved on the buckle body 21, and one end of the spring 23 abuts against a step on the outer wall of the buckle body 21; and a knob cap 24, which is connected to the embedded copper nut 22. The end of the buckle body 21 on which the spring 23 is sleeved is located inside the knob cap 24, and the other end of the spring 23 abuts against the bottom surface of the groove on the knob cap 24. The knob cap 24 is provided with a fixing screw 25, and the knob cap 24 is locked to the embedded copper nut 22 by the fixing screw 25.

[0027] In the above structure, the end of the buckle body 21 away from the knob cap 24 is provided with a locking part 211, which is used to press against the end face of the clamp. Preferably, the buckle body 21 is cylindrical, and the locking part 211 protrudes from one side of the outer wall of the cylindrical buckle body 21, and the locking part 211 is set at a right angle to the buckle body 21.

[0028] In the above structure, the outer wall of the buckle body 21 is provided with an annular boss 212, which is used to limit the buckle body 21 on the clamp. In addition, the outer wall of the buckle body 21 is provided with an annular step 213, and one end of the spring 23 abuts against the end face of the annular step 213. The annular step 213 forms a limiting surface of the spring 23.

[0029] In the above structure, the knob cap 24 has a first groove 241, one end of the buckle body 21 is disposed in the first groove 241, and the other end of the spring 23 away from the annular step 213 abuts against the bottom surface of the first groove 241. Preferably, the first groove 241 is a circular groove that cooperates with the cylindrical buckle body 21. The end of the buckle body 21 located in the first groove 241 has a second groove 214, and the embedded copper nut 22 is installed in the second groove 214. Preferably, the embedded copper nut 22 and the second groove 214 are interference-fitted.

[0030] In the above structure, the outer wall of the knob cap 24 is provided with a handle 242 for human hand gripping. Gripping the handle 242 facilitates rotation, thereby moving the buckle body 21 to or away from the engagement surface. The handle 242 has a through hole 243, which is on the same straight line as the embedded copper nut 22. One end of the stud of the fixing screw 25 passes through the through hole 243 and locks with the embedded copper nut 22. The end of the handle 242 away from the knob cap 24 has a third groove 244, which communicates with the through hole 243. This allows the stud of the fixing screw 25 to pass through the third groove 244 and the through hole 243, with the head of the fixing screw 25 abutting against the bottom surface of the third groove 244. The third groove 244 also accommodates the head of the fixing screw 25, preventing it from protruding and making it inconvenient for the hand to grip the handle 242.

[0031] A spring 23 is directly added to the buckle body 21. During assembly, the spring 23 is compressed by pressing the buckle assembly, and then the knob cap 24 is rotated to engage the locking part 211. The compressed spring 23 generates a counterforce to secure the product or cover. Selecting a suitable spring 23 will ensure a very secure buckle engagement. Conversely, the fastened part can be quickly removed by pressing the buckle assembly and rotating it to disengage the locking part 211. This design greatly improves the speed and efficiency of product assembly and disassembly. In addition, reliable and convenient assembly and disassembly can better ensure the stability and consistency of the production process, and will also have a positive impact on improving product quality during production. Example 2

[0032] Reference Figure 4-6 As shown, a clamp includes: a cover plate 1, a snap-fit ​​clamp assembly 2, and a base 3. The cover plate 1 and the base 3 are locked together by the snap-fit ​​clamp assembly 2, which is the elastic snap-fit ​​clamp described in Embodiment 1. The cover plate 1 and the base 3 are stacked and then locked together by the snap-fit ​​clamp assembly 2. When the clamp does not need to be locked, the engaging part 211 is rotated by the knob cap 24 to not contact the cover plate 1. At this time, under the elastic force of the spring 23, the annular boss 212 is pressed against the end face of the base 3. The base 3 has a fourth groove 31 at the position where the snap-fit ​​clamp assembly 2 is installed. The bottom surface of the fourth groove 31 has a through first through hole 32. One end of the knob cap 24 is located in the fourth groove 31, and when the end of the knob cap 24 contacts the bottom surface of the fourth groove 31, it is used to limit the pressing position of the knob cap 24. The first through hole 32 allows the snap-fit ​​body 21 to pass through.

[0033] In addition, a positioning pin 33 is provided on the end face of the base 3 opposite to the cover plate 1, and a positioning hole is provided on the cover plate 1. The positioning pin 33 is inserted into the positioning hole to realize the positioning of the base 3 and the cover plate 1.

[0034] The steps for installing the elastic buckle on the clamp according to this utility model are as follows:

[0035] During installation, first insert the spring 23 into the mounting guide post of the buckle body 21, then insert the entire assembly into the fixing hole of the base 3, install the knob cap 24, compress the spring 23, and secure the knob cap 24 to the buckle body 21 with the fixing screw 25, forming an integral elastic buckle fixed to the base 3. After installation, press the buckle body 21 with the knob cap 24 and rotate it. Rotate to the appropriate position and release. Utilizing the force generated when the spring 23 is compressed and released, the spring 23 drives the knob cap 24 to move during its elastic recovery. The knob cap 24 and the buckle body 21 are linked, thus pressing the engaging part 211 against the surface of the cover plate 1, which can quickly fix structural components such as the cover plate 1 and the base 3, greatly improving the speed and efficiency of clamping, fixing, and disassembling.

[0036] 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.
