Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figures 1 to 5, the end cap that blocks of the utility model linear laser diode comprises end cap cap 1, slide block 2 and thin bar 3, end cap cap 1 comprises cylindrical cavity 1-1, upper block 1-2 and lower block 1-3, upper block 1-2 and lower block 1-3 are symmetricly set on the both sides of cylindrical cavity 1-1 axis, upper block 1-2 is parallel with lower block 1-3, the spacing of upper block 1-2 and lower block 1-3 is less than the diameter of cylindrical cavity 1-1, described upper block 1-2 is provided with the T-slot 1-2-1 of perforation, and T-slot 1-2-1 is along the long side direction fluting of upper block 1-2; Described slide block 2 comprises integrated T shape pedestal 2-1 and boss 2-2, and boss 2-2 is positioned on the bottom face of T shape pedestal 2-1, and boss 2-2 is provided with the hole 2-2-1 of perforation; T shape pedestal 2-1 embeds in T-slot 1-2-1 and coordinates with its gapless.Described gapless coordinates and refers between T shape pedestal 2-1 and T-slot 1-2-1 to have enough friction force, makes the T shape pedestal 2-1 can landing from T-slot 1-2-1 when vertical state.T shape pedestal 2-1 and T-slot 1-2-1 are slidably connected; Boss 2-2 is positioned at the outside of T-slot 1-2-1, and hole 2-2-1 opens and vertical with the long limit of upper block 1-2 along the diametric(al) of cylindrical cavity 1-1; Described thin bar 3 is that diameter is the cylindrical bar of 1mm～1.5mm, and its top is fixed in the 2-2-1 of hole, and thin bar 3 is greater than the spacing of block 1-2 and lower block 1-3 from the length of boss 2-2 lower end exposed portions serve.
