Preferably, a plurality of the locating piece top all is provided with two and pastes the strip, two it bonds with the lens main part to paste the strip, is convenient for nimble taking out and assembly lens.

The utility model has the advantages as follows:

1. the utility model discloses a mutually support between through-hole, wind storehouse and ventilation pipe, through ventilation pipe and outside air pump switch-on, make the air pour into the wind storehouse, utilize the through-hole that is the annular setting to discharge, to the even blowout air current in lens surface, prevent that smoke and dust and work piece are close the lens to guaranteed the cleanness on lens surface, be convenient for better carry out laser engraving.

2. The utility model discloses be provided with locating piece and bonding strip, because the lens external diameter is less than lens frame internal diameter for there is certain space between lens and the lens frame inside wall, the user can bed hedgehopping or reduce the height of two bonding strips on the locating piece, thereby is convenient for adjust the installation angle of lens, and the lens adopts viscose and locating piece bonding, is convenient for take off and assemble, and it is very convenient that the operation is got up.
