Description

Multifunctional line projector

Technical Field

The utility model relates to the technical field of demarcation devices, in particular to a multifunctional demarcation device.

Background

In the existing market products, the laser modules of the line projector are fixed on the body by using screws or glue, so that most of the line projector is special for a special machine during use, namely, each line projector can be only singly applied to a certain working environment. Therefore, when a user needs to realize different functional requirements in the same working environment or often works in different working environments, the user needs to carry the traditional line projector of different models to adapt to the requirements of various occasions, which not only causes inconvenience of operation and carrying of the user, but also increases the use cost of the user. Therefore, the design of a line projector which can carry out various adaptability reorganizations according to the requirements of working environments and is applicable to most working environments is one of the research trends in the field.

For example, chinese patent publication No. CN207197516U discloses a line projector module, which can perform various adaptive recombination according to the requirements of working environments, so as to meet the requirements of most working environments. The line projector module comprises a base and a line projector unit, wherein the base and the line projector unit are provided with magnetic elements, the line projector unit is fixedly connected to the base through the magnetic elements, a power module is arranged in the line projector unit, and the line projector unit provides electric energy for a laser source through the power module of the line projector unit to enable the laser source to emit laser beams. However, since the power module is arranged in the line throwing unit, the volume and the mass of a single line throwing unit can be increased, and each line throwing module needs to be charged independently in actual use, the device is still inconvenient to carry and use in actual use.
