A buffer wheel 611 is fixedly connected to the top of the positioning sleeve 609. A pressure block 612 is provided at the top between the two limiting shells 603. By setting the buffer assembly 6, the engine body 1 can play a multi-directional buffer and shock absorption function. No matter what direction the engine body 1 deviates, it can play a good buffer and shock absorption function, improve the protection performance of the engine body 1, thereby avoiding damage to the engine body 1 during transportation or use and extending the service life of the engine body 1.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The surface of the limiting wheel 604 is slidably connected to the inner wall of the limiting shell 603, and the surface of the pressure block 612 is in contact with the surface of the buffer wheel 611. By setting the limiting shell 603, the use of the limiting wheel 604 can be facilitated, and by setting the pressure block 612, the use of the buffer wheel 611 can be facilitated.

[0028] Reference Figure 1 and Figure 4Fixing blocks 613 are fixedly connected to the front and rear sides of both sides of the base plate 601. A sliding rod 614 is fixedly connected to the top of the fixing block 613. A sliding sleeve 615 is fitted on the surface of the sliding rod 614. The surface of the sliding sleeve 615 is fixedly connected to the support block 2.

By setting the mounting plates 5, the stability of the engine body 1 during installation can be improved, and the installation of the engine body 1 can be facilitated.

[0030] Working principle: During operation or transport, the engine body 1 may vibrate due to various reasons, causing it to shift. This shift causes the support block 2 to shift, which in turn causes the limiting wheel 604 to shift. When the limiting wheel 604 shifts forward or backward or up or down, it is restricted by the limiting shell 603, which causes the limiting plate 605 to press the first spring 606. The shift of the support block 2 causes the sliding sleeve 615 to press the third spring 616. At the same time, when the support block 2 causes the pressure block 612 to shift, it presses the buffer wheel 611, causing it to shift. The buffer wheel 611 then moves the positioning sleeve 609 to press the second spring 610. Regardless of the direction of the shift, the first spring 606, the second spring 610, and the third spring 616 can effectively buffer and dampen the engine body 1, preventing damage and extending its service life.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
