As shown in
FIGS. 1 and 2
, a prior art office business machine like a scanner la has a lamp seat
11
a
disposed therein. A lamp tube

a
can be divided into single-tube type and double-tube type. A rack
13
a
for supporting the lamp tube
12
a
is disposed below the lamp tube
12
a
. In order to meet the compactness requirement of present products, the lamp tube
12
a
must be designed to be thinner. Therefore, the lamp tube
12
a
easily breaks because of vibration of the scanner
1
a
or careless fall during the transportation process.
Accordingly, the above lamp tube fixing structure has inconvenience and drawbacks in practical use. The present invention aims to resolve the problems in the prior art.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a lamp tube support structure, which is slipped onto a lamp tube to add support positions at two ends of the lamp tube for effectively preventing breakage of the lamp tube. Moreover, clamping effect can be achieved to protect the lamp tube from impact from all directions.
To achieve the above object, the present invention provides a lamp tube support structure, which comprises mainly a support piece applying to office business machines for supporting and fixing a lamp tube thereof. The lamp tube support structure comprises a first half and a second half. The first half has a gap for placing a lamp tube. A clamping portion is formed at two extension ends of the gap. Grooves are disposed at left and right ends of the second half. A wing portion is formed below the grooves. After the wing portion is bent, it can be jammed into a hole of a rack for supporting the lamp tube so as to be erectly fixed on the rack.
