The technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for the technicians in this field to make creative efforts.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
