DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model: an electrical instrument convenient to use, comprising:

[0023] The positioning assembly 1 comprises a positioning frame 11, the outer wall of the positioning frame 11 is fixedly connected to a guide shell 12, a pressing plate 16 is inserted in the guide shell 12 for vertical sliding, a guide plate 17 is inserted in the guide shell 12 and the positioning frame 11 for horizontal sliding, an abutment shaft 18 is fixedly connected to one end of the guide plate 17, and a first spring 19 is sleeved on the outer side of the abutment shaft 18;

[0024] The meter body 2 is plugged into the interior of the positioning frame 11, and the outer wall of the meter body 2 is connected to the positioning plate 21. The interior of the positioning plate 21 is plugged with a plug-in shaft 22, and the plug-in shaft 22 and the abutment shaft 18 are on the same axis. By pressing the pressure plate 16 downward, the guide plate 17 can be pushed, and then the plug-in shaft 22 can be squeezed by the displacement of the abutment shaft 18, so that the plug-in shaft 22 shrinks to the interior of the positioning plate 21. At this time, the meter body 2 can be pulled out upward to achieve quick disassembly of the meter body 2. The overall operation is simple and convenient, and no disassembly tools are required, which improves the convenience of disassembly and assembly of the meter body 2.

[0025] Furthermore, the outer wall of the guide shell 12 is fixedly connected to a cover plate 13, and the cover plate 13 is internally connected to a lever 14 in an up and down damping sliding manner. One end of the lever 14 located inside the guide shell 12 is fixedly connected to a connecting rod 15. Through the setting of the lever 14, synchronous pressing control can be performed through the pressure plate 16 of the same group, and the damping sliding connection has good stability to avoid rebound after pressing.

[0026] Furthermore, both ends of the connecting rod 15 are fixedly connected with a pressure plate 16, the lower surface of the pressure plate 16 is inclined, and the upper surface of the guide plate 17 corresponding to the pressure plate 16 is also inclined. Through the inclined setting, the stability of the abutment between the two can be improved, and at the same time, the pushing control of the guide plate 17 can be achieved by pressing the pressure plate 16.

[0027] Furthermore, a support frame 20 is fixedly connected to the interior of the positioning frame 11, and an abutment shaft 18 is inserted in the center of the lower half of the support frame 20, and a first spring 19 abuts between the support frame 20 and the guide plate 17. Through the setting of the first spring 19, the rebound processing of the abutment shaft 18 is realized, and the pressure plate 16 is pulled up to reset. At this time, the abutment shaft 18 and the guide plate 17 are reset by the elastic force of the first spring 19, and then when the watch body 2 is plugged in and installed, the plug-in shaft 22 can be plugged into the interior of the support frame 20.

[0028] Furthermore, the inclined surface of the pressure plate 16 and the inclined surface of the guide plate 17 fit each other, and two groups of abutment shafts 18 are provided, and the two groups of abutment shafts 18 are symmetrically distributed on both sides of the positioning frame 11, and each group of abutment shafts 18 is provided with two.

[0029] Furthermore, a limiting ring is provided at one end of the plug-in shaft 22 close to the positioning plate 21, and the plug-in shaft 22 is connected to the positioning plate 21 in a limited sliding manner. A second spring 23 is provided inside the positioning plate 21, and one end of the second spring 23 abuts against the plug-in shaft 22. A first inclined surface is provided on the lower surface of the plug-in shaft 22, and a second inclined surface is provided on the upper surface of the support frame 20. The setting of the inclined surface of the support frame 20 can guide the insertion of the watch body 2, and at the same time, the plug-in shaft 22 is contracted to facilitate the insertion of the watch body 2, until the plug-in shaft 22 moves to the coaxial line of the abutment shaft 18, and is affected by the elastic force of the second spring 23, so that the plug-in shaft 22 extends out and is plugged into the inside of the support frame 20, thereby completing the locking and positioning of the watch body 2, and the diameter of the plug-in shaft 22 can be equal to the diameter of the abutment shaft 18.

[0030] Working principle: 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 all existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the watch body 2 is first plugged into the interior of the positioning frame 11, and the plug-in shaft 22 is guided by the inclined surface of the support frame 20, so that it shrinks to the interior of the positioning plate 21, until the plug-in shaft 22 is plugged into the coaxial line with the abutment shaft 18, the elastic force of the second spring 23 makes the plug-in shaft 22 extend and plug into the interior of the support frame 20, so that the watch body 2 can be quickly installed. When disassembly is required, the guide plate 17 and the abutment shaft 18 can be pushed by pressing the lever 14 downward, and then the connecting rod 15 drives the pressure plate 16 to move downward, and the abutment shaft 18 can be pushed by the abutment shaft 18 to push the plug-in shaft 22, so that the plug-in shaft 22 shrinks to the interior of the positioning plate 21. At this time, the watch body 2 is pulled upward to achieve disassembly of the watch body 2.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
