Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To keep the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known parts of the invention has been omitted.

As shown in fig. 1-2, a mechanical lifting device for four-side brushes of a sweeper comprises a base frame 8, a fixing seat 7 fixed at the bottom of the base frame 8, a limiting clamp 4 which is elastically connected in the fixing seat 7 and can rotate, a front double-brush main body 1 which is rotatably connected at the front side of the base frame 8, a limiting rod 11 which is fixed at the root of the front double-brush main body 1 and is positioned at the front side of the limiting clamp 4, and a pedal 3 which is fixed at the end part of the limiting rod 11 and is movably inserted and arranged in the base frame 8, ratchet teeth 111 are formed on the limiting rod 11 backwards, the ratchet teeth 111 are matched with the front end of the limiting clamp 4, a height limiting block 9 is further fixed at the top of the base frame 8, and the height limiting block 9 is matched with the root part of the limiting rod 11.

A cavity hole 81 is formed in the base frame 8, the pedal 3 is movably inserted into the cavity hole 81, and the end of the height limiting block 9 extends out of the upper portion of the front side of the opening of the cavity hole 81.

The front side of base frame 8 still is fixed with bearing fixing base 10, and both ends still all are equipped with a bearing 2 about bearing fixing base 10, preceding double brush main part 1 rotatable connection between two bearings 2.

Still alternate in the spacing card 4 and be provided with rotatable axle sleeve 6, the left and right sides at fixing base 7 is fixed respectively at the both ends of axle sleeve 6.
