[0028] A slide groove 146 is provided on the side where the side strip A144 and the side strip B145 are close to each other. The limit strip 155 is slidably installed inside the slide groove 146. The limit strip 155 moves into the slide groove 146 to limit the position between the plug plate 154 and the side strips A144 and B145.

[0029] In this embodiment: when assembling the left shell 14 and the right shell 15, the left shell 14 and the right shell 15 are held by hand, and the internal components of the voltage regulating device 1 can be installed on the top of the plug plate 154, and the side strips A144 and the side strips B145 are placed on both sides of the side middle curved plate 131, and the plug plate 154 and the limiting strips 155 arranged on both sides are stuck between the side outer curved plate A132 and the side outer curved plate B133, pushing the left shell 14 and the right shell 15 together, and the limiting strip 155 is inserted into the inside of the slide groove 146, and the plug plate 154 is inserted between the side strips A144 and the side strips B145, and the lower ends of the left shell 14 and the right shell 15 are assembled.

[0030] Example 2: Please refer to Figure 2-4 A side insert rod 142 is installed at the inner upper end of the left shell 14, a threaded groove 143 is opened on the outer side of the middle end of the side insert rod 142, and a side concave holding strip A141 is installed on the outer side of the left shell 14.

It is connected to the outer surface of the side insertion rod 142 with a threaded groove 143, and is fixed between the opposing plate 111, the side insertion rod 142 and the middle rotation tube 152. Since the insertion plate 154 is stuck in the inside of the slide groove 146 through the limiting strip 155, the pressure regulating device 1 can keep the left shell 14 and the right shell 15 stable when in use. Conversely, the middle rotation tube 152 can be rotated out of the outer side of the threaded groove 143, and the side concave holding strip A141 and the side concave holding strip B151 can be held to pull out the left shell 14 and the right shell 15, so as to facilitate the maintenance of the spare parts.

The middle rotation tube 152 on the outer side of the side concave holding strip B151 is held and rotated, and fixed between the opposing plate 111, the side insertion rod 142 and the middle rotation tube 152. Since the insertion plate 154 is stuck in the inside of the slide groove 146 through the limiting strip 155, the pressure regulating device 1 can keep the left shell 14 and the right shell 15 stable when in use. Conversely, the middle rotation tube 152 can be rotated out of the outer side of the threaded groove 143, and the side concave holding strips A141 and the side concave holding strips B151 can be held to pull out the left shell 14 and the right shell 15, which is convenient for maintenance of the parts.
