[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example

[0021] This utility model provides, for example Figures 1-3The pneumatic aging crimping device with automatic short-circuit function shown includes a mounting plate 1, a cylinder 2 connected to the mounting plate 1, several meter holders 3 on the mounting plate 1, several movable slots 9 inside the meter holders 3, movable sleeves 8 inside the movable slots 9, and connecting rods 4 inside the movable sleeves 8. The connecting rods 4 have square parts, and the movable sleeves 8 are fitted onto the square parts. The width of the movable slots 9 is greater than the width of the movable sleeves 8, providing space for the left and right adjustment of the connecting rods 4. A spring 7 is fitted onto the connecting rods 4, and the spring 7 pushes the connecting rods 4 to move downward. The upper end of the connecting rods 4 is connected to a movable short-circuit piece 5. A fixed short-circuit piece 6 is set on the upper part of the meter holders 3. When the movable short-circuit piece 5 moves downward and contacts the fixed short-circuit piece 6, the two adjacent connecting rods 4 of the fixed short-circuit piece 6 are connected, realizing the short circuit of the electricity meter, and the electricity meter can then be removed.

[0022] A rack 10 is provided on the movable sleeve 8. A rack drive wheel 11 is provided on one side of the rack 10 and on the meter receiving frame 3. An opening is provided on the meter receiving frame 3, and the rack drive wheel 11 is located in the opening. A gear is provided on the rack drive wheel 11, and the gear meshes with the rack 10. Rotating the rack drive wheel 11 drives the rack 10 to rotate, thereby realizing the left and right movement of the movable sleeve 8, which can adjust the position of the connecting rod 4, thus making it suitable for different models of electricity meters.

[0023] like Figures 4-5 As shown, the upper part of the meter holder 3 is provided with a slot-shaped opening, and the upper limiting device 12 of the connecting rod is embedded in the slot-shaped opening; the upper limiting device 12 of the connecting rod includes a slot-shaped frame 121 and a ring 123. The slot-shaped frame 121 is provided with a fixing ear 124, and a countersunk screw is installed in the fixing ear 124 to fix the entire upper limiting device 12 of the connecting rod in the slot-shaped opening. An annular groove 122 is opened around the inner wall of the slot-shaped frame 121, and the edge of the ring 123 is stuck in the annular groove 122. The upper end of the connecting rod 4 is sleeved in the ring 123; the upper limiting device 12 of the connecting rod is used to limit the upper part of the connecting rod 4 to prevent it from tilting, so that the upper part of the connecting rod 4 moves with the left and right movement of the movable sleeve 8, so that it always remains in a vertical state.

[0024] During use, the pneumatic aging crimping device with automatic short-circuit function has the energy meter placed under the connecting rod 4. When the cylinder 2 is activated, the connecting rod 4 moves downward with the mounting plate 1. After the connecting rod 4 contacts the energy meter, the mounting plate 1 continues to move downward, so that the movable short-circuit piece 5 and the fixed short-circuit piece 6 are connected, and the energy meter can be connected to the power supply. When the connecting rod 4 moves upward with the mounting plate 1, the connecting rod 4 separates from the energy meter. Under the action of the spring 7, the movable short-circuit piece 5 contacts the fixed short-circuit piece 6, so that the two connecting rods 4 adjacent to the fixed short-circuit piece 6 are connected, realizing the short circuit of the energy meter, and the energy meter can then be removed.
