[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figure 1-4 This utility model discloses an electrical instrument that is easy to disassemble and maintain. The mounting component 1 includes: a mounting frame 101, a snap-fit ​​bracket 102, a lifting spring 103, a lifting plate 104, a push spring 105, and a pull rod 106. The left and right side walls of the mounting frame 101 are provided with pull-out grooves. The pull rod 106 is located on the inner wall of the pull-out groove, facilitating the movement of the snap-fit ​​bracket 102. Two sets of push springs 105 are respectively fixedly connected to the opposite side walls of the inner cavities of the left and right pull-out grooves, facilitating the movement of the snap-fit ​​bracket 102. In position, two sets of snap-fit ​​brackets 102 are fixedly connected to the opposite ends of two sets of push springs 105. The snap-fit ​​brackets 102 facilitate the fixing of the positioning frame 201. The snap-fit ​​brackets 102 are connected to the pull rod 106. The snap-fit ​​brackets 102 are L-shaped. The opposite side walls of the two sets of snap-fit ​​brackets 102 are provided with snap-fit ​​grooves. The bottom wall of the inner cavity of the snap-fit ​​brackets 102 is provided with grooves. The lifting springs 103 are fixedly connected to the bottom wall of the inner cavity of the grooves. The lifting springs 103 facilitate the pushing of the lifting plate 104 to move upward. The lifting plate 104 is provided on the top wall of the lifting spring 103.

[0024] The watch body 2 is inserted into the interior of the mounting frame 101. The outer wall of the watch body 2 is fixedly connected to the positioning frame 201. The positioning frame 201 facilitates the limiting and fixing of the watch body 2. The positioning frame 201 matches the snap-fit ​​groove. The watch bodies 2 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] In this embodiment: During installation, the watch body 2 is placed inside the mounting frame 101. Pressing down on the watch body 2 moves the positioning frame 201, which in turn pushes the snap-fit ​​bracket 102 to the snap-fit ​​slot. The spring force of the push spring 105 then moves the snap-fit ​​bracket 102, which snaps into and secures the positioning frame 201, facilitating the installation and fixation of the watch body 2. During disassembly, pulling the lever 106 moves the snap-fit ​​bracket 102. The movement allows the locking bracket 102 to release its locking to the positioning frame 201. The lifting spring 103 then pushes the lifting plate 104 to move, which in turn moves the positioning frame 201. The positioning frame 201 then moves the meter body 2 upward, causing it to pop out partially to the outside of the mounting frame 101 for easy removal and disassembly. This device facilitates the installation and removal of the meter body 2, making it easier for workers to perform subsequent maintenance. Disassembly can be completed without tools, which improves the efficiency of the workers.

[0026] Limiting strips 107 are fixedly connected to the front and rear side walls of the inner cavity of the mounting frame 101. The positioning frame 201 is located on the top wall of the limiting strip 107.

[0027] In this embodiment, the limiting strip 107 is concave. The limiting strip 107 facilitates the positioning frame 201 to be limited. The limiting strip 107 cooperates with the snap-fit ​​bracket 102 to fix the positioning frame 201. The positioning frame 201 facilitates the installation and fixation of the watch body 2. This allows the device to easily limit and fix the watch body 2, preventing the watch body 2 from shifting or loosening, and enabling the quick installation and fixation of the watch body 2.

[0028] The top wall of the lifting plate 104 is provided with an installation groove. The front and rear side walls of the installation groove are evenly connected to the rotating rollers 108. The rotation of the rotating rollers 108 facilitates rolling on the bottom wall of the positioning frame 201.

[0029] In this embodiment: when the mounting body 2 is installed, the positioning frame 201 moves to the snap-fit ​​groove. The positioning frame 201 abuts against the top wall of the rotating roller 108. The push spring 105 facilitates the movement of the snap-fit ​​bracket 102. The snap-fit ​​bracket 102 drives the lifting spring 103 to move. The lifting spring 103 drives the lifting plate 104 to move. The lifting plate 104 drives the rotating roller 108 to move, so that the rotating roller 108 rolls on the bottom wall of the positioning frame 201. This makes it easier for the device to snap the positioning frame 201, avoids the friction between the lifting plate 104 and the positioning frame 201 from affecting the movement of the snap-fit ​​bracket 102, and is beneficial for limiting and fixing the positioning frame 201.

[0030] The outer wall of the pull rod 106 is square, and the inner wall of the pull slot matches the outer wall of the pull rod 106.

[0031] In this embodiment, the outer wall of the pull rod 106 is square, and the pull groove facilitates the movement of the pull rod 106 to limit the movement, prevent the pull rod 106 from deflecting, prevent the snap-fit ​​bracket 102 from shifting, and facilitate the snap-fit ​​with the positioning frame 201.

[0032] The upper sides of the opposite sidewalls of the two sets of card holders 102 are inclined, and the bottom wall of the positioning frame 201 is arc-shaped.

[0033] In this embodiment, the upper sides of the opposite sidewalls of the snap-fit ​​bracket 102 are inclined, which facilitates the positioning frame 201 to push the snap-fit ​​bracket 102 to move, making it easier to install and fix, and improving the installation speed.
