In operation, the cabinet door 13 can be opened first, and the ammeter body 17 can be installed on the top of the support seat 15 after the probe 16 on the support seat 15 is aligned with the terminal post 171 on the ammeter body 17. The above steps are repeated until all the ammeter bodies 17 are installed. Then the clamping plate 18 can be controlled to clamp and fix the ammeter body 17. Subsequently, the cabinet door 13 can be closed so that the ammeter body 17 can face the code scanner 117. The connection structure between the cabinet 12 and the cabinet door 13 can be a prior art, which will not be described here. The first motor 19 is started to drive the directly connected circular plate 111 to rotate. The circular plate 111 can drive the first branch arm 112 to rotate. In the process, the first branch arm 112 can exert a pushing force on the sliding block 115 through the connected connecting shaft 113 and the crank 1141, so that the sliding block 115 slides along the circular ring 116. At the same time, since the axis of the circular plate 111 and the axis of the connecting shaft 113 can form one long side A of a parallelogram, and the center of the circular ring 116 and the axes of the crank 1141 and the sliding block 115 can form another long side a, the lengths of the two long sides should be equal. The circular plate 111 and the center of the circular ring 116 can form a short side B, and the crank 1141 and the axis of the sliding block 115 and the axis of the connecting shaft 113 can form another short side b. Therefore, when the circular plate 111 rotates, b should always be parallel to B, that is, the components composed of the crank 1141, the connecting shaft 113 and the mounting plate 114 can always remain horizontal during rotation. During the movement of the code scanner 117, the bar code on the outer wall of the ammeter body 17 arranged in a circle can be identified one by one, and the identification information can be transmitted to the controller 14. After identification is completed, the first motor 19 can be turned off, and the ammeter body 17 can be verified through the probe 16 and the terminal post 171. After verification is completed, the cabinet door 13 can be opened, and the ammeter body 17 can be removed from the support seat 15 after the fixation of the ammeter body 17 by the clamping plate 18 is released. It is worth mentioning that the first motor 19 can be a reduction motor. In addition, the support seat 15 and the ammeter body 17 shown in the figure are arranged in multiple numbers. In actual use, the number of ammeter bodies 17 arranged in a circle can be increased uniformly according to the specific detection requirements, that is, the proficiency of the operator, so as to adapt the operation time of the operator.

[0026] Please refer to Figures 2 to 5 As shown in the figure, the second branch arm 2 is also fixed to the circular plate 111. The second branch arm 2 is also provided with a retaining assembly. The balance plate 22 is rotatably connected between adjacent mounting plates 114, and the axis of the balance plate 22 on the mounting plate 114 is arranged in a staggered manner with the connecting shaft 113. The sliding power of the slider 115 comes from the crank 1141, and the balance plate 22 can connect the adjacent mounting plates 114 as a whole, wherein one mounting plate 114 can transmit power to the crank 1141 directly connected to the other mounting plate 114 through the balance plate 22, thereby improving the stability and balance of the crank 1141 when pushing the slider 115 to slide; by setting the balance plate 22, the slider 115 can slide more stably along the circular ring 116, improving the stability of the movement process.

[0027] Please refer to Figures 2 to 5 As shown, the inner wall of the circular ring 116 is symmetrically provided with a limiting sliding groove; a plurality of guide wheels 3 are symmetrically and rotatably connected to the slider 115, and the guide wheels 3 are located inside the limiting sliding groove on the circular ring 116. By setting the guide wheels 3, the slider 115 can slide in the limiting sliding groove in the circular ring 116 through the guide wheels 3. The guide wheels 3 can roll when moving, which can limit the slider 115 on one hand and improve the stability of the slider 115 when sliding along the circular ring 116, and on the other hand can reduce the sliding friction between the slider 115 and the circular ring 116.

[0028] Please refer to Figures 6 to 8 As shown, the cavity is provided in the cabinet door 13, and the second motor 4 is fixedly arranged in the cavity; the output end of the second motor 4 is fixedly connected with the first gear 42; the first gear 42 is rotatably connected with the inner wall of the cabinet door 13; a plurality of second gears 43 are rotatably connected in the cabinet door 13; the second gears 43 are in meshing relationship with the first gear 42; an arc-shaped sliding groove is formed in the second gear 43; a plurality of horizontal sliding grooves are formed in the cabinet door 13; the clamping plate 18 is slidably connected with the horizontal sliding groove on the cabinet door 13 and the arc-shaped sliding groove on the second gear 43 through the fixing pin. After the ammeter body 17 is installed on the probe 16, the second motor 4 can be controlled to start, driving the directly connected first gear 42 to rotate. The first gear 42 can mesh with a plurality of second gears 43, and the second gears 43 can be synchronously rotated. A plurality of second gears 43 can drive a pair of clamping plates 18 to move towards each other through the cooperation of the arc-shaped sliding groove and the horizontal sliding groove on the cabinet door 13, so as to clamp and fix the ammeter body 17, thereby simplifying the operation when fixing all ammeter bodies 17. Here, the second motor 4 can be a reduction motor.

[0029] Please refer to Figures 8 to 10As shown, the clamping plate 18 is fixedly connected with a pair of pull ropes 5 at the bottom; the clamping plate 18 is of T-shaped structure, and the clamping surface facing the meter body 17 is provided with a hollow structure for avoiding the pull rope 5; the end of the pull rope 5 is fixedly connected with a supporting plate 52, and a plurality of circular holes for passing through the probe 16 are formed in the surface of the supporting plate 52; a plurality of positioning rods 53 are fixedly connected to the bottom of the supporting plate 52; the bottom of the positioning rod 53 is fixedly connected with a limiting plate, and the positioning rod 53 is in penetrating arrangement with the supporting seat 15 and is in sliding connection; When the meter body 17 is checked, the bottom shell is in abutment with the supporting plate 52, as shown in Figure 9 As shown, after the checking is completed, the first gear 42 can be reversely driven by controlling the second motor 4 to make the pair of clamping plates 18 move away from each other, and the pull rope 5 can be pulled during the movement of the clamping plate 18, so that the supporting plate 52 is vertically lifted under the limiting action of the positioning rod 53, and the probe 16 can be lifted during the upward movement of the supporting plate 52, so that the wire column 171 on the meter body 17 can be separated from the probe 16, thereby achieving the lifting of the meter body 17, as shown in Figure 10 As shown, then the meter body 17 can be directly taken off from the supporting plate 52 by the worker, which simplifies the operation of vertically pulling out the meter body 17 along the probe 16. Before checking the next batch of meter bodies 17, the pair of clamping plates 18 can be moved close to each other by controlling the second motor 4 to reset the supporting plate 52, thereby avoiding the interference of the supporting plate 52 with the placement of the meter body 17. This is a pre-adjustment operation. In addition, compared with the cylinder lifting method, the cylinder lifting method needs to sequentially arrange cylinders at the bottom of the supporting seat 15 and design and connect the gas circuit of the cylinder, which occupies a large amount of installation space. The above-mentioned method can save the installation space on the cabinet door 13 and save the electrical linkage setting of multiple cylinders.

[0030] As shown in Figures 8 to 10 The supporting seat 15 is fixedly connected with a plurality of vertical plates 6 at the top; three first pulleys 62 are rotatably connected to the vertical plate 6; and a groove for sliding the pull rope 5 is formed in the first pulley 62. The three first pulleys 62 can guide the movement track of the pull rope 5, that is, the pulling force of the pull rope 5 on the supporting plate 52 can be in the vertical direction, which can reduce the horizontal component of the pulling force of the pull rope 5 on the supporting plate 52 when the clamping plate 18 is reset, thereby improving the stability of the vertical movement of the supporting plate 52.

[0031] As shown in Figure 9 and Figure 10 The first pulley 62 is provided with a second pulley 7 on one side; the second pulley 7 is rotatably connected with the inner wall of the vertical plate 6; and the pull rope 5 is located between the second pulley 7 and the first pulley 62. When the size of the meter body 17 to be checked is smaller than the size shown in the figure, that is, when checking, the distance between the clamping plates 18 is shorter, and the pull rope 5 may be detached from the first pulley 62 due to slack. By additionally providing the second pulley 7, the second pulley 7 and the first pulley 62 can constrain and limit the pull rope 5, thereby reducing the slack and detachment of the pull rope 5 caused by the small size of the meter body 17, and avoiding the winding between adjacent pull ropes 5.

[0032] Please refer to Figure 9 As shown, the bottom of the support seat 15 is fixedly connected with a spring 8; the top of the spring 8 and the limiting plate on the positioning rod 53 are in fixed connection; By setting the spring 8, in the initial state, the spring 8 is normal length, when a pair of clamping plates 18 move away from each other, that is, the positioning rod 53 moves upward along the support seat 15, the spring 8 is in compression state, the spring 8 exerts a downward force on the positioning rod 53, which can ensure that the subsequent reset of the supporting plate 52 can quickly move downward and reset under the action of its own gravity and the elastic force of the spring 8.

[0033] Please refer to Figure 8 and Figure 11 As shown, the top of the support seat 15 is fixedly connected with at least one pair of rubber rods 9; the wiring port 172 and the rubber rod 9 are in interference fit; By setting the rubber rod 9, when the meter body 17 is sleeved on the probe 16 through the wiring post 171, the rubber rod 9 can also be inserted into the inside of the wiring port 172, and the meter body 17 can be temporarily fixed on the supporting plate 52 through the friction between the rubber rod 9 and the supporting plate 52 during the subsequent jacking of the meter body 17 by the supporting plate 52, and since the rubber rod 9 has a certain elasticity, the meter body 17 does not have to be vertically lifted to be removed.

[0034] Please refer to Figure 1 and Figure 6 As shown, a plurality of heat dissipation holes 10 are formed on the outer side of the cabinet door 13, and the heat dissipation holes 10 are arranged towards the second motor 4; By setting the heat dissipation hole 10, the heat dissipation hole 10 can ventilate the internal cavity of the cabinet door 13, and timely discharge the heat generated by the second motor 4 during operation.

[0035] Working principle: first open the cabinet door 13, by artificial alignment on the meter body 17 on the terminal post 171 and the probe 16 on the support seat 15, then install the meter body 17 to the top of the support seat 15, repeat the above steps until all the meter body 17 is installed, then control the clamping plate 18 to clamp and fix the meter body 17, then close the cabinet door 13, so that the meter body 17 can be towards the code scanner 117, the connecting structure between the cabinet 12 and the cabinet door 13 can be prior art, which will not be described here, start the first motor 19 to drive the straight connected round plate 111 to rotate, the round plate 111 can drive the first branch arm 112 to rotate, in the process, the first branch arm 112 can exert a pushing force on the slider 115 through the connected connecting shaft 113 and the crank 1141, so that it slides along the circular ring 116, at the same time, since the axis of the round plate 111 and the axis of the connecting shaft 113 can form a long side A of a parallelogram, the center of the circular ring 116 and the shafts between the crank 1141 and the slider 115 can form another long side a, the length of the two long sides should be equal, the round plate 111 and the center of the circular ring 116 can form a short side B, and the crank 1141 and the slider 115 shaft and the axis of the connecting shaft 113 can form another short side b, so when the round plate 111 rotates, b should be parallel to B at all times, that is, the components composed of the crank 1141, the connecting shaft 113 and the mounting plate 114 can be kept horizontal during rotation, the code scanner 117 can identify the bar code on the outer wall of the meter body 17 during movement, and transmit the identification information to the controller 14, after identification, the first motor 19 can be turned off, and the meter body 17 can be verified through the probe 16 and the terminal post 171, after verification, the cabinet door 13 can be opened, the fixing of the meter body 17 by the clamping plate 18 can be released, and the meter body 17 can be removed from the support seat 15, it is worth mentioning that the first motor 19 can be a reduction motor; the sliding power of the slider 115 comes from the crank 1141, and the balance plate 22 can connect the adjacent mounting plates 114 as a whole, one of the mounting plates 114 can transmit power to the crank 1141 connected to the other mounting plate 114 through the balance plate 22, thereby improving the stability and balance of the crank 1141 when pushing the slider 115 to slide; by providing the guide wheel 3, the slider 115 can slide in the limiting sliding groove in the circular ring 116 through the guide wheel 3, the guide wheel 3 can roll during movement, which can limit the slider 115 and improve the stability of the slider 115 when sliding along the circular ring 116, and on the other hand, it can reduce the sliding friction between the slider 115 and the circular ring 116;After the ammeter body 17 is installed on the probe 16, the second motor 4 can be controlled to start, driving the directly connected first gear 42 to rotate. The first gear 42 can be engaged with a plurality of second gears 43, and the second gears 43 are synchronously rotated. The plurality of second gears 43 can drive a pair of clamping plates 18 to move towards each other through the cooperation of the arc-shaped sliding groove and the horizontal sliding groove on the cabinet door 13, so as to clamp and fix the ammeter body 17. The operation of fixing all ammeter bodies 17 is simplified. Here, the second motor 4 can be a speed reducer. When the ammeter body 17 is checked, the bottom shell abuts against the supporting plate 52. After the checking is completed, the first gear 42 can be reversed by controlling the second motor 4, so that the pair of clamping plates 18 move away from each other. The clamping plates 18 can pull the pull rope 5 during movement. The pull rope 5 exerts an inclined pulling force on the supporting plate 52. The supporting plate 52 can vertically rise under the limiting action of the positioning rod 53. The supporting plate 52 can lift the ammeter body 17 during upward movement, so that the terminal post 171 on the ammeter body 17 can be separated from the probe 16, thereby achieving the lifting of the ammeter body 17. Then, the staff can directly take the ammeter body 17 from the supporting plate 52, thereby simplifying the operation of vertically pulling out the ammeter body 17 along the probe 16. Before checking the next batch of ammeter bodies 17, the second motor 4 can be controlled to rotate slightly, so that the pair of clamping plates 18 are close to each other at one end distance, thereby resetting the supporting plate 52 and avoiding interference with the placement of the ammeter body 17. This is a pre-adjustment operation. The movement track of the pull rope 5 can be guided by the three first pulleys 62 distributed in staggered manner. The pulling force of the pull rope 5 on the supporting plate 52 can be in the vertical direction, thereby reducing the horizontal component of the pulling force of the pull rope 5 on the supporting plate 52 during resetting of the clamping plate 18, and improving the stability of the vertical movement of the supporting plate 52. When the size of the ammeter body 17 to be checked is smaller than the size shown in the figure, the distance between the clamping plates 18 is shorter during checking. At this time, the pull rope 5 will be disconnected from the first pulley 62 due to relaxation. The second pulley 7 is additionally provided to constrain and limit the pull rope 5, thereby reducing the relaxation and disconnection of the pull rope 5 due to the small size of the ammeter body 17, and avoiding the entanglement between adjacent pull ropes 5. The spring 8 is provided in the initial state. When the pair of clamping plates 18 move away from each other, the positioning rod 53 moves upward along the support seat 15, the spring 8 is in a compressed state, and the spring 8 exerts a downward force on the positioning rod 53. The supporting plate 52 can quickly move downward and reset under the action of its own gravity and the elastic force of the spring 8 during subsequent resetting of the supporting plate 52.By setting the rubber rod 9, the electric meter body 17 is sleeved on the probe 16 through the binding post 171, the rubber rod 9 can also be inserted into the binding port 172, and the electric meter body 17 can be temporarily fixed on the supporting plate 52 through the friction between the rubber rod 9 and the electric meter body 17 when the electric meter body 17 is subsequently jacked by the supporting plate 52, and since the rubber rod 9 has a certain elasticity, the electric meter body 17 does not have to be vertically pulled to be removed; by setting the heat dissipation hole 10, the heat dissipation hole 10 can ventilate the internal cavity of the cabinet door 13, and the heat generated during the operation of the second motor 4 can be discharged in time.
