The adjustable bag dust collector elliptical skeleton, by providing a limiting mechanism, enables the skeleton to have a limiting function, achieves the effect of limiting the connecting rod, thereby facilitating the adjustment of the length of the connecting rod, and then adjusting the length of the skeleton, so that it is suitable for bags of different sizes, and then conveniently installed on bag dust collectors of different sizes, reducing the cost of bag dust collector spare parts, facilitating the use of users, and increasing the practicality of the skeleton.

[0004] However, the above patent still has certain disadvantages when in use: it adjusts the height of the frame by adjusting the height of the connecting rod inside the fixing groove, but the dimensions of the fixing groove and the connecting rod are fixed, which results in the dimensions that can actually be adjusted being within a certain range, thereby limiting the overall expansion range, and the structures are closely connected, so once local damage occurs, the entire structure needs to be replaced, which has a greater impact on the overall situation, is not conducive to subsequent maintenance operations, and reduces the use effect of the device.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
