Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a receiving device of laser plummet, including manual heightening base 1, receive target 2 and layer board 3, the output of manual heightening base 1 with the bottom of layer board 3 is connected, receive target 2 and include target body 21 and a plurality of magnetism foot 22, the downside of target body 21 with a plurality of magnetism foot 22 one end is connected, layer board 3 is iron, the other end of magnetism foot 22 with layer board 3 upper portion magnetism is connected, target body 21 center department is provided with cross target scale 211.
