[0026] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application

[0027] The embodiment of this application provides an integrated tool for installing and disassembling elastic rail clips, which can solve the problem that multiple tools need to be carried during construction and maintenance operations, and the transportation and use processes are relatively cumbersome

[0028] Refer to Figure 1 , Figure 1 Schematic diagram of the integrated tool for installing and disassembling elastic rail clips in the embodiment of this application. As Figure 1 shown, in one embodiment, the integrated tool includes a handle 1, a driving claw 2 and a positioning claw 3. The driving claw 2 is fixedly arranged at the bottom end of the handle 1, and the positioning claw 3 is hinged on the driving claw 2. The positioning claw 3 further includes a first hook part 31 for installing the elastic rail clip and a second hook part 32 for disassembling the elastic rail clip. The first hook part 31 and the second hook part 32 are arranged up and down. When installing the elastic rail clip, the first hook part 31 is stuck on the embedded base of the elastic rail clip, and the driving claw 2 abuts against the tail of the elastic rail clip; when disassembling the elastic rail clip, the second hook part 32 is stuck on the embedded base of the elastic rail clip, and the driving claw 2 abuts against the head of the elastic rail clip

[0029] In this embodiment, when installing the elastic clip fastener, the first hook portion 31 of the positioning claw 3 is stuck on the embedded base of the elastic clip fastener, and the driving claw 2 is abutted against the tail of the elastic clip fastener. Since the positioning claw 3 is hinged to the driving claw 2, and the driving claw 2 is fixedly arranged at the bottom end of the handle 1, therefore, by reciprocating the top end of the driving handle 1 back and forth, the driving claw 2 can be driven to pry the tail of the elastic clip fastener to displace, ensuring that the elastic clip fastener is evenly and accurately fastened on the embedded base of the elastic clip fastener, avoiding problems of loosening or deviation caused by improper installation, and improving the stability and safety of the railway track system.

[0030] When disassembling the elastic clip fastener, the second hook portion 32 of the positioning claw 3 is stuck on the embedded base of the elastic clip fastener, and the driving claw 2 is abutted against the head of the elastic clip fastener. By reciprocating the top end of the driving handle 1 back and forth, the driving claw 2 can be driven to pry the head of the elastic clip fastener to displace, ensuring that the elastic clip fastener is evenly disassembled from the embedded base of the elastic clip fastener. The operation is simple and very labor-saving.

[0031] It should be noted that the longer the length of the set handle 1 is, the more labor-saving the installation and disassembly of the elastic clip fastener will be.

[0032] As Figure 1 shown, in some embodiments, the handle 1 is a rectangular tube. In this embodiment, by setting the handle 1 as a rectangular tube, it can be ensured that the handle 1 can withstand greater forces and torques during use, is not easily bent or broken, and improves the structural strength and stability of the handle 1.

[0033] As Figure 1 shown, in some embodiments, one end of the driving claw 2 is inserted into the bottom end of the handle 1 and welded to the handle 1 integrally, and the driving claw 2 and the positioning claw 3 are connected by a pin shaft 4. In this embodiment, one end of the driving claw 2 is inserted into the bottom end of the handle 1, and the driving claw 2 is welded to the handle 1 by welding, which greatly enhances the strength between the two, ensuring that the driving claw 2 will not fall off or loosen due to excessive force during use. And the driving claw 2 and the positioning claw 3 are connected by a pin shaft 4, which can not only ensure high connection precision between the driving claw 2 and the positioning claw 3, but also ensure the reliability and stability of the connection. Secondly, the pin shaft 4 connection can withstand greater forces and replacement torques, which is very beneficial for the installation and disassembly of the elastic clip fastener.

[0034] Refer to Figure 2 , Figure 2 This is Figure 1 a schematic diagram of the driving claw 2 in this application. As Figure 2As shown, in some embodiments, an obtuse angle is formed between the front end face of the driving claw 2 and the front end face of the handle 1. In this embodiment, by setting the front end face of the driving claw 2 and the front end face of the handle 1 to form an obtuse angle, the force transmission between the driving claw 2 and the handle 1 can be maximized, which facilitates the installation and removal of the spring clip fastener by the driving claw 2.

[0035] like Figure 2 As shown, in other embodiments, the four corners of the end of the driving claw 2 inserted into the handle 1 are all chamfered, which makes it easier for the driving claw 2 to be inserted into the handle 1, saving time and effort.

[0036] like Figure 1 As shown, in some embodiments, the positioning claw 3 can be turned 180 degrees around the pin 4. In this embodiment, since the first hook portion 31 and the second hook portion 32 of the positioning claw 3 are arranged on the positioning claw 3 up and down, according to actual use, only the positioning claw 3 can be turned 180 degrees around the pin 4, so that when the user installs or removes the spring clip fastener, the first hook portion 31 and the second hook portion 32 can be flexibly switched without re-adjusting the position or removing and reinstalling. Moreover, such a design method can also effectively utilize space and avoid space waste caused by the positioning claw 3 being unable to rotate.

[0037] like Figure 1 As shown, in some embodiments, the positioning claw 3 includes a connecting plate 33 and two claw pieces 34 fixed on both sides of the connecting plate 33, the connecting plate 33 is located at the front end of the claw piece 34, and the driving claw 2 is hinged between the claw pieces 34 on both sides through the pin 4, and is located at the rear end of the claw piece 34. In this embodiment, the positioning claw 3 includes a connecting plate 33 and two claw pieces 34 fixed on both sides of the connecting plate 33. By using the connecting plate 33 as a supporting base and being located at the front end of the claw piece 34, the overall stability of the positioning claw 3 is enhanced, so that it remains stable when fixing the spring clip fastener, and is not prone to deformation or failure. The claw pieces 34 on both sides are simultaneously stuck on the embedded base of the spring clip fastener, which can prevent the positioning claw 3 from moving or falling off. In addition, the driving claw 2 is hinged between the claw pieces 34 on both sides through the pin 4, and is located at the rear end of the claw piece 34, which not only facilitates the installation, disassembly and replacement of the driving claw 2, but also can adjust the position and angle of the driving claw 2, thereby realizing the installation and disassembly of the spring clip fastener.

[0038] Reference Figure 3 , Figure 3 For this application Figure 1 The schematic diagram of the connection between the middle driving claw 2 and the fixed claw is as shown in Figure 3As shown, in some embodiments, positioning spacer sleeves 22 are fixedly provided on both sides of the driving claw 2. The positioning spacer sleeves 22 are sleeved on the pin shaft 4 and are located between the driving claw 2 and the claw piece 34. In this embodiment, by fixedly providing positioning spacer sleeves 22 on both sides of the driving claw 2, and sleeving the positioning spacer sleeves 22 on the pin shaft 4 and locating them between the driving claw 2 and the claw piece 34, the friction of direct contact between the driving claw 2 and the claw piece 34 is reduced, thereby reducing the wear rate. At the same time, the positioning spacer sleeves 22 can also play a certain supporting role, facilitating the force transmission between the driving claw 2 and the claw piece 34.

[0039] As Figure 3 As shown, in some embodiments, an impact plate 21 for reciprocally impacting the elastic clip fastener is provided at the front end of the driving claw 2. The position height of the impact plate 21 is lower than the position height of the connecting plate 33. In this embodiment, by providing an impact plate 21 for reciprocally impacting the elastic clip fastener at the front end of the driving claw 2, and the position height of the impact plate 21 is lower than the position height of the connecting plate 33, the driving claw 2 can directly act on the elastic clip fastener, and by means of the impact plate 21 reciprocally impacting the elastic clip fastener, the rapid installation or disassembly of the elastic clip fastener can be realized. When the impact plate 21 reciprocally impacts the elastic clip fastener, the position height of the impact plate 21 is lower than the position height of the connecting plate 33, avoiding forming unnecessary obstacles, resulting in poor impact effect of the impact plate 21, or even possibly damaging other components.

[0040] As Figure 1 As shown, in some embodiments, handles 11 are provided on both sides of the top end of the handle 1. In this embodiment, by providing handles 11 on both sides of the top end of the handle 1, the user can hold the handle 1 more stably, reducing the risk of the handle sliding or falling off, thereby ensuring the accuracy and safety of the operation.

[0041] As Figure 1 As shown, in some embodiments, the surface of the integrated tool is covered with an anti-rust coating. In this embodiment, the integrated tool is made of metal. By covering the surface of the integrated tool with an anti-rust coating, it can effectively prevent the metal material from directly contacting corrosive media such as oxygen and moisture in the air, thereby effectively preventing metal oxidation and corrosion, protecting the overall structure and performance of the tool, and at the same time reducing the material replacement and maintenance costs caused by corrosion.

[0042] In this embodiment, when installing the elastic clip fastener, the first hook portion of the positioning claw is stuck on the embedded base of the elastic clip fastener, and the driving claw is placed at the tail of the elastic clip fastener. By reciprocating the top end of the driving handle back and forth, the driving claw fixed to the bottom end of the handle is driven to pry the tail of the elastic clip fastener, so as to ensure that the elastic clip fastener is evenly and accurately fastened on the embedded base of the elastic clip fastener, avoiding problems such as loosening or deviation caused by improper installation, and improving the stability and safety of the railway track system.

[0043] When the elastic clip fastener is disassembled, the second hook portion of the positioning claw is stuck on the embedded base of the elastic clip fastener, and the driving claw is placed on the head of the elastic clip fastener. By reciprocating back and forth at the top of the driving handle, the driving claw fixed to the bottom end of the handle is driven to pry the head of the elastic clip fastener, ensuring that the elastic clip fastener is evenly disassembled from the embedded base of the elastic clip fastener, which is simple and labor-saving. Through this embodiment, the technical problem in the related art that when carrying out railway construction and maintenance operations, it is not necessary to carry a variety of tools to complete the installation and disassembly of the elastic clip fastener is solved.
