[0007] A slidable T-shaped arm is arranged in the cross-shaped groove, and a positioning piece is arranged on the crossbeam and can fix the position of the T-shaped arm;
[0008] The two clamping parts are matched and arranged in the abdominal cavities on both sides of the rail respectively, and the clamping parts are fixedly connected to the lower section of the T-shaped arm.
[0009] Preferably, a handle is welded on the top of the T-shaped arm, and the handle protrudes from the cross-shaped groove.
[0010] Preferably, two groups of through holes are provided in the crossbeam, and a reserved hole is provided at the top end of the T-shaped arm.
[0011] Preferably, the positioning member is a positioning pin arranged in the through hole and the reserved hole.
[0012] Preferably, a plurality of ribs are respectively provided on the front and rear sides of the T-shaped arm, and the ribs are welded between the clamping portion and the T-shaped arm.
[0013] Preferably, the interior of the T-shaped arm is hollow, the interior of the clamping portion is hollow, and the front and rear sides thereof are open.
[0014] Preferably, a plurality of support plates are fixedly connected to the inner cavity of the clamping portion.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model slides the T-arm into the cross groove on the corresponding side, makes the clamping part contact with the belly of the rail, inserts the positioning pin into the through hole and the reserved hole, and then fixes the position of the T-arm, so that the two clamping parts clamp the rail. The clamping is convenient and fast, saving time and effort, and the contact area between the clamping part and the rail is large, which can improve the clamping effect and ensure the stability of the rail clamping.
[0017] 2. The utility model can separate the clamp from the rail by removing the T-shaped arm on one side, which is convenient for disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS
