Further, described clamp along top board length direction interval arrange three.
Further, described support bar differs from the one end being hinged on lower branch arm and has positioning trough.
Further, described support bar differing from one end end face being hinged on lower branch arm is inclined-plane.
Further, described top board has crossed beam trunking near one end of lower branch arm.
Further, the width of described crossed beam trunking is 5 ~ 8mm.
Further, described connecting hole is the through hole of band heavy stand.
The advantage that the utility model has and positively effect are:
1) lifting head in single crystal growing furnace adopts single bracing frame to fix, and avoid the energy imbalance after traditional use two bracing frame life-time service, lifting head is stablized, and crystal mass is high.
2) upper branch arm and support bar all can be accommodated in the groove of lower branch arm, such folding structure design, be easy to storage, transport and easy for installation.
3) support bar is located by clamp, and can be inserted in the positioning trough of support bar through positioning through hole by positioning elements such as steady braces, and achieve Dual positioning, bracing frame is safe and reliable.
4) one end that support bar and top board are conflicted is inclined-plane, and the one end avoiding support bar to be blocked by clamp and top board interfere.

Embodiment
It should be noted that, in not afoul situation, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of folding right angle support frame, as shown in Figure 1, comprises lower branch arm 1, the upper branch arm 2 of concave structure and one end and is articulated with support bar 3 in the middle part of lower branch arm 1; Described upper branch arm 2 comprises the biside plate 5 that top board 4 and top board 4 both sides are parallel to each other; Described upper branch arm 2 one end is hinged on lower branch arm 1 top by hinge 6, and its concave-shaped openings down; Described lower branch arm 1 has the groove 7 that can hold upper branch arm 2; Top board 4 side be in concave-shaped openings of described upper branch arm 2 is provided with the clamp 8 of several positioning support strut 3 cantilever one end at different positions; At least one side plate 5 of described upper branch arm 2 is provided with positioning through hole 9, at least one sidewall of the groove 7 of lower branch arm 1 is provided with pilot hole 15; Described upper branch arm 2 and lower branch arm 1 are equipped with connecting hole 10.
It should be noted that, as shown in Figure 2, upper branch arm 2 and support bar 3 all can be accommodated in the groove 7 of lower branch arm 1, such folding structure design, be easy to storage, transport and easy for installation.
Wherein, described support bar 3 differs from the one end being hinged on lower branch arm 1 and have positioning trough 11.Can insert in the positioning trough 11 of support bar 3 through positioning through hole 9 by positioning elements such as steady braces, achieve Dual positioning, this bracing frame use safety, reliable and stable.
Wherein, as shown in Figure 3, the end face that described support bar 3 differs from the one end being hinged on lower branch arm 1 is inclined-plane 12, and one end that support bar 3 is blocked by clamp 8 and top board 4 can not interfere, and what support bar 3 can be firm is supported on inside clamp 8.In addition, fillet 13 transition can be processed in one end support bar 3 being hinged on lower branch arm 1, support bar 3 and lower branch arm 1 can be avoided to interfere, groove 7 degree of depth reducing lower branch arm 1 can also tried one's best like this, ensure overall construction intensity.
Wherein, described top board 4 has crossed beam trunking 14 near one end of lower branch arm 1, and cable can pass crossed beam trunking 14, and the groove 7 through lower branch arm 1 passes, and has both served constraint location cable, has also played protection to cable simultaneously.
Wherein, the width of described crossed beam trunking 14 is 5 ~ 8mm, and crossed beam trunking 14 reduces size when ensureing that cable can pass as far as possible, is conducive to ensureing overall construction intensity.
Wherein, described connecting hole 10 is the through hole of band heavy stand, and time fixing with bolt etc., the nut of bolt can sink in the heavy stand of connecting hole 10, not only saves space, avoids the interference on recurring structure, and bolt is accurately positioned simultaneously, and fixation is reliable.
During use, rotate upper branch arm 2 and adjust the angle of itself and horizontal plane, then support bar 3 free end is propped up on corresponding clamp 8, support bar 3 is located by clamp 8, and can positioning through hole 9 be passed by positioning elements such as steady braces and insert in the positioning trough 11 of support bar 3, achieve Dual positioning, this bracing frame is safe and reliable.
Due to described clamp 8 along top board 4 length direction interval arrange three.Like this, support bar 3 can be against on different clamps 8, the fixing of upper branch arm 2 different angles can be realized.It should be noted that, general lifting head is all mounted on horizontally disposed upper branch arm 2, but run into special operation condition, upper branch arm 2 can suitably tilt, and horizontal by certain angle, it is more firm that lifting head is fixed.
Lifting head in single crystal growing furnace adopts single bracing frame to fix by the utility model, and avoid the energy imbalance after tradition use two bracing frame life-time service, lifting head is stablized, and crystal mass is high.Meanwhile, upper branch arm 2 and support bar 3 all can be accommodated in the groove 7 of lower branch arm 1, such folding structure design, be easy to storage, transport and easy for installation.
