[0018] The following will refer to the appendix in the embodiments of this utility model. Figure 4-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A novel elastic clamp mounting device includes a pry bar 3, the bottom of which is provided with a lifting hook 301; the lifting hook 301 is used to mount an elastic clamp 2. The improvement of this utility model lies in that: the lower part of the pry bar 3 is provided with an outwardly extending L-shaped support 5, the L-shaped support 5 spans the upper surface of the slide plate 1 and forms a prying fulcrum 4 for the pry bar 3 at the bottom of the slide plate 1.

[0020] This invention utilizes an L-shaped support 5 as the prying fulcrum 4 of the crowbar 3, effectively preventing damage to the surface of the slide plate 1 from the elastic clamp installation device, thus enhancing protection. The lower part of the crowbar 3 has an outwardly extending L-shaped support 5 that spans the upper surface of the slide plate 1 and forms a prying fulcrum 4 at the bottom of the slide plate 1. When installing the elastic clamp 2, the lever principle can be utilized more efficiently, reducing the force and time required during installation. The bottom of the crowbar 3 has a lifting hook 301 for installing the elastic clamp 2. Simultaneously, the L-shaped support 5 in the lower part of the crowbar 3 provides greater flexibility to adapt to different installation environments. Whether in confined spaces or on complex installation surfaces, this device provides a stable prying fulcrum, ensuring smooth installation. Through the design of the prying fulcrum 4 of the crowbar 3, the elastic clamp 2 can be installed without direct contact with the upper surface of the slide plate 1. This non-direct contact installation reduces damage to the upper surface of the slide plate 1, maintaining its flatness and smoothness, which is beneficial for subsequent use and maintenance.

[0021] In the above embodiment, furthermore: the prying fulcrum 4 is provided with an arc surface 401, which is used to prevent scratching the surface of the slide plate 1. The design of the arc surface 401 makes the contact between the prying fulcrum 4 and the surface of the slide plate 1 smoother. During the prying process, the arc surface 401 can reduce the direct contact area with the surface of the slide plate 1, thereby reducing friction and wear, extending the service life of the slide plate 1, and reducing surface damage caused by friction and wear. The design of the arc surface 401 can disperse stress, reduce the occurrence of stress concentration, and effectively protect the surface of the slide plate 1 from damage. The design of the arc surface 401 makes the movement of the prying fulcrum 4 on the surface of the slide plate more stable. During the installation of the elastic clamp 2, the operator can more accurately control the position and direction of the prying fulcrum 4, thereby improving the installation accuracy and helping to reduce surface damage to the slide plate 1 caused by improper operation. As a crucial component, the integrity and aesthetics of the slide plate 1 are vital to the overall appearance of the equipment. The design of the arc surface 401 maintains the flatness and smoothness of the slide plate 1 surface, preventing scratches or dents during installation. Prying using a stable fulcrum avoids wobbling or displacement caused by unstable fulcrums during installation, thereby improving installation accuracy and success rate.

[0022] In the above embodiments, furthermore, the L-shaped support 5 and the crowbar 3 are integrally formed. The integral forming of the L-shaped support 5 and the crowbar 3 ensures a seamless connection without welding or splicing gaps, significantly improving the overall structural strength and stability. Under stress, the integral design can more effectively disperse stress, reduce stress concentration, and avoid structural damage caused by excessive local stress. Since there are no connecting parts between the L-shaped support 5 and the crowbar 3, the risk of wear and loosening in these parts during long-term use is reduced. The integral design can typically use more corrosion-resistant materials or undergo more comprehensive anti-corrosion treatment, thereby increasing the service life of the entire device. The integral molding process reduces assembly steps and the number of parts in the manufacturing process, thus reducing production costs. Because the integral design reduces the number of connecting parts, the risk of the entire device failing due to connecting part failure is reduced. The integral design makes the entire device more compact and simple in structure, facilitating maintenance and upkeep. The integral molding process can reduce surface defects caused by welding, splicing, and other processes, improving the surface quality of the product.

[0023] In the above embodiment, furthermore: the thickness of the L-shaped support 5 across the slide plate 1 is adapted to the thickness of the slide plate 1. This adaptation of the L-shaped support 5's thickness to the slide plate 1 ensures that the L-shaped support 5 fits tightly against the bottom of the slide plate 1, forming a stable support structure. The adapted support thickness effectively prevents the crowbar 3 from wobbling due to unstable fulcrum during prying, improving the stability and accuracy of the installation operation. Because the L-shaped support 5 is adapted to the thickness of the slide plate 1, the operator can find the prying fulcrum of the crowbar more quickly, without repeatedly adjusting the position and direction of the crowbar 3, thereby improving installation efficiency. The adapted support thickness reduces the time required for repeated adjustments due to unstable fulcrum, making the installation process smoother. The adapted support thickness avoids scratching or abrasion of the slide plate 1 surface by the L-shaped support 5 during prying, protecting the integrity and aesthetics of the slide plate 1. By reducing stress damage to the slide plate 1, the appropriate support thickness helps extend the service life of the slide plate and reduce replacement costs.

[0024] In the above embodiments, furthermore, the crowbar 3 and the lifting hook 301 are integrally formed using a conical structure that is wider at the top and narrower at the bottom. This integral forming makes the connection between the crowbar 3 and the lifting hook 301 more robust, eliminating welded or spliced ​​gaps and thus enhancing the overall structural strength. The conical structure design makes the connection between the crowbar 3 and the lifting hook 301 more robust. Under stress, this structure effectively disperses stress, avoids stress concentration, and improves the load-bearing capacity of the structure. Because the crowbar 3 and the lifting hook 301 are integrally formed and employ a conical structure design, wear on the connection points is reduced. During long-term use, this design maintains the good condition of the crowbar 3 and the lifting hook 301, extending their service life. The conical structure design also makes it easier to apply force to the lifting hook 301 during operation. Operators can easily insert the lifting hook 301 into the position where the elastic clip 2 needs to be installed using the crowbar 3, improving operational convenience. Because the crowbar 3 and the lifting hook 301 are integrally molded, and the connection is robust and reliable, operational errors caused by loose or broken connections are reduced, improving operational accuracy and reliability. The integral molding process reduces assembly steps and the number of parts in the manufacturing process, lowering production costs and increasing production efficiency.

[0025] The working principle of this utility model is as follows: making full use of the principle of mechanics, the lifting hook 301 is inserted into the bottom of the slide plate 1 where the elastic clip 2 needs to be installed, and at the same time, the L-shaped support 5 spans the upper surface of the slide plate 1 and forms the prying fulcrum 4 of the crowbar 3 at the bottom of the slide plate 1. Using the lever principle, the crowbar 3 is pressed down, which plays the role of lifting the lifting hook 301, thereby achieving the effect of quickly lifting the elastic clip 2 on one side. The operation is convenient and quick, reducing the number of operators, and is more time-saving and labor-saving. The operation process is simple, efficient, non-destructive, safe and reliable.

[0026] As can be seen from the above description, this utility model uses the arc surface 401 of the L-shaped support 5 as the prying fulcrum 4 of the crowbar 3. The L-shaped support 5 spans the upper surface of the slide plate 1 and forms the prying fulcrum 4 at the bottom of the slide plate 1, effectively preventing damage to the chrome plating layer on the upper surface of the slide plate 1 by the elastic mounting device, thus enhancing protection. This utility model has higher structural strength, requires less effort to pry, is more convenient to operate, reduces labor intensity, and improves work efficiency.

[0027] It should be understood that although this specification describes one embodiment, it does not mean that the embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in this embodiment can also be appropriately arranged and combined to form other embodiments that can be understood by those skilled in the art.
