The two screws are finely dynamically balanced, supported by bearings, and installed in the pump casing. There is a certain gap between the screws, and the working chamber does not require lubricating oil. It has the advantages of higher ultimate vacuum, lower power consumption, energy saving, and maintenance-free. In actual applications, in order to keep the dry spiral vacuum pump in a better working state, shaking and vibration sounds will occur when the dry spiral vacuum pump is used. A protective mechanism is usually installed to protect the dry spiral vacuum pump.

[0026] In this embodiment, through the joint action of the pump body 1, the mounting base 2, and the connecting component 3, the device can be made more stable to use. If the pump body 1 is installed internally through the top, the installation angle will be limited, so the mounting base 2 is fixedly connected to the bottom of the device. The connection of the mounting base 2 makes the installation of the components behind the device more convenient. The elastic rod 34 is fixed to the mounting base. By aligning the bottom of the support platform 31 with the top of the elastic rod 34, the piston rod 35 can be fixed. At the same time, the bottom of the connecting component 3 can also be protected by the buffering force through the elastic rod 34, so that when the subsequent device is installed, the loss caused to the bottom connection is reduced, making the device more convenient to use. Example
[0027] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the buffer mechanism 4 includes a connecting block 41, the upper and lower ends of the connecting block 41 clamp a clip 42, the interior of the clip 42 is provided with three groups of mounting grooves 43, the interior of the mounting groove 43 is provided with an elastic part 44, and the interior of the connecting plate 5 is penetrated by a fixing nut 51.
[0028] The buffer mechanism 4 is composed of four groups of connecting blocks 41 . The connecting blocks 41 are in a U shape. The connecting blocks 41 are connected to the connecting pieces 5 by fixing nuts 51 .
[0029] In this embodiment, the device can be made more convenient to use through the joint action of the connecting component 3, the buffer mechanism 4 and the connecting piece 5. The buffer mechanism 4 is a small component part, which is connected together by the connecting piece 5. The connecting piece 5 can be removed to facilitate disassembly and replacement of the devices and maintenance. At the same time, the buffer mechanism 4 is connected through the connecting component 3, which makes the device connection more stable during use.

The upper and lower ends of the connecting seat 441 are fixedly connected to the damper, and the elastic parts are bidirectionally supported, so that the device is more stable when working, and the vibration force generated is reduced. The buffer mechanism 4 is connected through the connecting component 3, and then the bottom of the support platform 31 is aligned with the top of the elastic rod 34 for connection, so that the piston rod 35 can be fixed. The bottom of the connecting component 3 can also be protected by the buffering force through the elastic rod 34, so that when the subsequent device is installed, the loss caused to the bottom connection is reduced, making the device more convenient to use.
