[0052] Step 1, the detection object, i.e. the circuit to be tested, is a distribution box and a fixed line of the whole house. One end (input end) of the detection object is electrically connected with the first, second and third wiring bases of the connection seat of the acceptance instrument according to needs, and the other end (output end) is connected with the terminal seat and terminal according to needs. Specifically, when conducting non-live detection, the other end is only connected with the terminal seat, specifically connected with the connection seat of the terminal seat; when conducting live detection, the other end is connected with the connection seat of the terminal seat, and the terminal is inserted into the socket of the terminal seat. The terminal seat and the terminal can both adopt the terminal seat and the terminal described below;

[0053] Step 2, non-live detection is conducted by the acceptance instrument, the first, second and third contact rods are simultaneously adjusted to be in contact with the third, sixth and ninth contact points respectively by the three-gear adjusting mechanism (i.e. 45° in the figure), then the connection lines in the "third, sixth and ninth contact points are electrically connected with connection lines, the connection lines are used to be electrically connected with the corresponding binding posts of the megohmmeter" are electrically connected with the corresponding binding posts in the megohmmeter according to needs, so as to measure the insulation resistance between the lines and complete the insulation detection.

[0054] Step 3, the first, second and third contact rods are simultaneously adjusted to be in contact with the first, fourth and seventh contact points respectively by the three-gear adjusting mechanism (i.e. -45° in the figure), then the connection lines in "the fourth contact point 8 is electrically connected with a connection line, the connection line is used to be electrically connected with the corresponding binding post of the multimeter, the inner rotating end of the fourth contact rod 4 is electrically connected with a connection line, the connection line is used to be electrically connected with the corresponding binding post of the multimeter" are electrically connected with the corresponding binding posts in the multimeter according to needs, and the fourth contact rod 4 can be selected to be in contact with the tenth contact point 14 or the eleventh contact point 15 by the two-gear adjusting mechanism, so as to realize the fire-ground, fire-zero and zero-ground resistance detection.

[0055] Step 4: live detection is conducted by the acceptance instrument, the inner rotating ends of the first, second and third contact rods are electrically connected with connection lines respectively, and the connection lines are used to be electrically connected with the live wire, the fire wire and the ground wire, there are three connection lines, which can be integrated into a three-phase plug and inserted into the socket to access the city power for live detection.

[0056] The three-gear adjusting mechanism simultaneously adjusts the first, second and third contact rods to be in contact with the first, fourth and seventh contact points respectively (i.e. -45° in the figure), and then the connection line in "the fourth contact point 8 is electrically connected with a connection line for electrically connecting with a corresponding binding post of a multimeter, and the inner rotating end of the fourth contact rod 4 is electrically connected with a connection line for electrically connecting with a corresponding binding post of a multimeter" is electrically connected with the corresponding binding post in the multimeter, and the fourth contact rod 4 is selected to be in contact with the tenth contact point 14 or the eleventh contact point 15 by the two-gear adjusting mechanism, so that voltage and current detection, circuit on-off detection and whether the fire-zero-fire connection is on or not are realized.

[0057] The acceptance instrument can perform insulation and voltage resistance detection on the detection object at one time, reduce the number of times of wiring and disconnecting the wiring, and improve the detection efficiency.

[0058] As shown in Figures 1-7 As a specific embodiment, the body further comprises a leakage protector, the leakage protector has a fire wire incoming wire binding post, a zero wire incoming wire binding post, a fire wire outgoing wire binding post and a zero wire outgoing wire binding post, the connection lines electrically connected with the inner rotating ends of the first and second contact rods are respectively electrically connected with the zero wire outgoing wire binding post and the fire wire outgoing wire binding post, and the zero wire incoming wire binding post and the fire wire incoming wire binding post are respectively electrically connected with a commercial zero wire and a fire wire.

[0059] Before the live detection, i.e. after the aforementioned step 3 and before step 4, the leakage detection can be performed, and the detection is realized by the leakage protector. Specifically, after step 3, the first, second and third contact rods need to be simultaneously adjusted to be in contact with the second, fifth and eighth contact points (i.e. 0° in the figure) by the three-gear adjusting mechanism, the three-gear three-section conversion switch is switched to the zero position, the commercial power is connected, the leakage protector is turned on, and whether there is leakage is detected. If not, step 4 detection, i.e. voltage detection, is performed.

[0060] In normal operation, the outgoing wire of the leakage protector is connected with a load (an electrical appliance), and the fire wire current and the zero wire current are equal in size; if leakage occurs in the line, the fire wire current and the zero wire current will no longer be equal, and the sum of the two is equal to the leakage current. When the zero wire and / or the fire wire is detected to be leaked, the leakage protector controls the power supply to be disconnected.

The hand screw bolt 17 can be obtained by increasing the nut of a common bolt.

[0064] As shown in Figure 8 embodiment, the inner hole profile size of the hollow column 16 is adapted to the cross-sectional profile of the wire. After the wire is inserted into the hollow column 16, the thimble 18 pierces the wire, and the wire is tightly pressed by the bolt, so that conduction is realized.

[0065] As shown in Figure 8 embodiment, the inner hole cross section of the hollow column 16 has an angle, and the wire is pressed tightly in the angle after the bolt is screwed into the hollow column 16.
