Embodiment two

The present embodiment is the application that formula bracket is supported to touching in embodiment one, and the present embodiment is related to a kind of handheld slit lamp, The illuminating source of slit-lamp (portion b) for supporting formula bracket including touching in embodiment one and being supported on formula bracket for being connected to touching.

As shown in Figure 5 and Figure 6, attachment base 904 is connected at the top of illuminating source of slit-lamp, illuminating source of slit-lamp is used for Ribbon slit of illumination is launched outward by its light hole 1-2.

According to Fig. 6 and Fig. 7, illuminating source of slit-lamp in the present embodiment, including shell 1, shell 1 are by two and half Shell pairing is constituted, in the present embodiment, the mirror settings such as default conduit on two half-shell inner walls.In varied situations, two Half-shell can also be replaced by other structures with same function.

As shown in figure 8, being equipped with LED illuminating module 2, convex lens 13, adjustable crack component 3, control module inside shell 1 And power supply module.

As shown in Figure 9, wherein before LED illuminating module 2 includes pole-shaped radiator 2-1 and is connected to pole-shaped radiator 2-1 The LED light-emitting particles 2-2 at end.It is equipped with 2 mounting groove 1-3 of LED illuminating module in shell 1, offers company in the bottom of mounting groove 1-3 Lead to the radiator window 1-1 outside shell 1.

Wherein, control module is used to control the switch of LED illuminating module 2 and the power of issued light.Control module includes Pcb board 4.Pcb board 4 is equipped with control circuit, and control circuit includes rotary switch 5, and shell 1 is equipped with the rotation for rotary switch 5 The through slot that button stretches out.Control circuit further includes key switch 6, and the button of key switch 6 stretches out in except shell 1.

Wherein, power supply module is used to power for LED illuminating module 2.Power supply module includes battery 7, is also set on pcb board 4 There are USB charging slot 8 and a charge management circuit, charge management circuit by USB charging slot 8 takes electricity from the external world and to battery 7 chargings.

As shown in Figure 10, adjustable crack component 3 includes that a pair is set side by side and plate 3-1 in crack adjustable in pitch；It is a pair of Crack plate 3-1 is set to the front at 2 beam projecting end of LED illuminating module, and the setting of convex lens 13 is in LED illuminating module 2 and a pair In optical path between the plate 3-1 of crack.

It for the structure of adjustable crack component 3, specifically can be used as preferably: further including threaded post 3-2 and crack Plate 3-1 limits walking trough.The both ends of threaded post 3-2, which are equipped with, adjusts finger wheel 3-3, in the present embodiment: offering on shell 1 for spiral shell The through-hole that the line both ends column 3-2 are stretched out adjusts finger wheel 3-3 and is connected at the both ends other than the shell 1 that threaded post 3-2 is stretched out in.It can It is further preferred that adjusting between finger wheel 3-3 and the end of threaded post 3-2 as clamping.

Mantle fiber has contrary external screw thread 912 respectively on the two half portion surface of left and right of threaded post 3-2.A pair of of crack plate 3-1 Top be connected with nut body 3-4, a pair of of crack plate 3-1 is connected respectively to the left and right of threaded post 3-2 by nut body 3-4 Two half portions.It is to be used for the bottom for a pair of of crack plate 3-1 by two inwardly protruding formation of half-shell that crack plate, which limits walking trough 3-5, Portion is embedded in and limits it and rotates with threaded post 3-2, when rotating threaded post 3-2 by the adjusting finger wheel 3-3 of either side, because splitting Gap plate limit walking trough 3-5 prevent a pair of crack plate 3-1 with threaded post 3-2 rotation, so crack plate 3-1 can only be located remotely from each other or It is close, to achieve the purpose that adjust Fracture Width therebetween.It is of course also possible to replace with damp type sliding slot and crack plate 3-1 Above scheme is changed, is repeated no more.

Light hole 1-2 is offered on shell 1, is light passing road 9 between light hole 1-2 and a pair of crack plate 3-1.In this implementation In example, light passing road 9 is U-shaped, and each corner in U-shaped light passing road 9 is respectively equipped with the reflecting mirror 10 horizontal by predetermined angle. For further the ribbon light through generating after the plate 3-1 of crack is adjusted, it is also used as being preferably: a pair of of crack plate The first lens 11 are additionally provided between 3-1 and first reflecting mirror 10.Further, the second lens 12 are equipped at light hole 1-2.

The utility model is not limited to the above embodiment, the technical solution of above-mentioned each embodiment of the utility model that This can form new technical solution with combined crosswise, and in addition all technical solutions formed using equivalent replacement, are all fallen within practical In the protection scope of novel requirement.
