Referring to fig. 1 and 2, a simple supporting device applied to a PCB 100 is mainly used for placing the PCB 100 on an operation table, and comprises a first supporting member 1 and a second supporting member 2, which are matched to suspend the PCB 100 on the operation table, so that direct contact between the PCB 100 and the operation table is avoided, structural damage of the PCB 100 is prevented, structural integrity of the PCB 100 is effectively ensured, service life of the PCB 100 is prolonged, damage to the PCB 100 due to moving the PCB 100 on the operation table during overhauling of the PCB 100 is prevented, defects existing in the background art are effectively solved, and assembly efficiency is high.

In detail, referring to fig. 1 and 2, the first supporting member 1 is annular, a through hole 101 is formed in a middle portion of the first supporting member 1, a second supporting member 2 mounted in cooperation with the first supporting member 1 has a positioning column 201 extending outwards, the positioning column 201 is mounted in cooperation with the through hole 101, the positioning column 201 is used for extending into a mounting hole of the PCB board 100, and when the positioning column 201 of the second supporting member 2 extends into the mounting hole, the first supporting member 1 is sleeved on the positioning column 201 of the second supporting member 2 through the through hole 101, and the first supporting member 1 and the second supporting member 2 are both magnetic and are magnetically attracted and connected. That is, the first support member 1 and the second support member 2 are attracted to each other by their own magnetism, wherein the first support member 1 and the second support member 2 have limited magnetism due to their smaller volume, and do not affect the elements on the PCB board 100. Therefore, the installation mode of mutual attraction is adopted, the installation between the two can be realized rapidly, meanwhile, the complex processing procedures like a universal jig are not needed in the practical application, the efficiency can be improved while the whole processing flow is optimized, and the defects in the background technology are overcome well.

Further, the length of the positioning column 201 on the second support member 2 can be determined according to the actual thickness of the PCB 100, a longer positioning column 201 can be selected when the thickness of the PCB 100 is larger, and a shorter positioning column 201 can be selected when the thickness of the PCB 100 is smaller, which needs to be considered according to the actual situation.

As an alternative embodiment, referring to fig. 1 and 2, a boss 3 is further provided on the first support member 1, and an inner diameter of the boss 3 is smaller than an inner diameter of the first support member 1. The boss 3 has the functions of: because when in use, the first supporting piece 1 is directly contacted with the PCB 100, the boss 3 is arranged, so that the contact area between the first supporting piece 1 and the PCB 100 can be reduced, the probability of damaging the structure of the PCB 100 is reduced, the protection of the structural integrity of the PCB 100 is facilitated, and the service life is prolonged.

Further, as a preferred embodiment, the first supporting member 1 is a nut, and the positioning post 201 is a stud, and the nut and the stud are matched and installed. That is, when the installation of the second support member 2 on the PCB board 100 is completed, the first support member 1 is rapidly and rotatably installed on the second support member 2 through the connection relationship of the rotational connection between the screw cap and the screw bolt, so that the efficiency is high, the method of using the jig in the conventional technology is well replaced, the method of placing the PCB board 100 on the operation table is greatly optimized, and the user experience is excellent. Furthermore, in order to place the PCB board 100 on the operation table more stably, the above functions can be realized by setting multiple groups of the first supporting members 1 and the second supporting members 2, and in practical application, the two are mainly installed through the installation holes on the PCB board 100, and the specific installation process is as follows: firstly, the positioning column 201 on the second support piece 2 is extended downwards into the mounting hole, and then the first support piece 1 is rotatably mounted at the extending position of the positioning column 201 at the bottom of the PCB 100, namely, the mounting between the screw cap and the stud is realized. In addition, it should be noted that, the nut and the stud are not all magnetic, and only a part of the positions of the nut and the stud, such as the contact surface of the nut and the stud or the position of the stud on the inner side where the nut and the stud are in contact with each other, so that the deviation generated when the nut and the stud magnetically attract each other due to excessive magnetic force is avoided, the structural integrity of the product is protected, and the stability of the nut and the stud magnetically attracts each other is improved.
