[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, this utility model discloses a stage light pole clamping device, including a first clamping arm 1, a second clamping arm 2, an adjusting rod 3, a drive handle 4, an adjusting part 5, a first locking part 6, and a rotating rod 7.

[0026] The first clamping arm 1 is provided with a receiving groove 11 for receiving the rod body 8, wherein the rear end of the first clamping arm 1 away from the receiving groove 11 is provided with a first extension 12.

[0027] One end of the second clamping arm 2 passes through the receiving groove 11, wherein the center of the second clamping arm 2 is rotatably connected to the first clamping arm 1. It should be understood that the rod body 8 is actually clamped by the clamp formed by the first clamping arm 1 and the second clamping arm 2 (hereinafter referred to as the clamp), and is not received in the receiving groove 11.

[0028] One end of the adjusting rod 3 is rotatably connected to the other end of the second clamping arm 2.

[0029] One end of the drive handle 4 is rotatably connected to the first extension 12, and the middle part of the drive handle 4 is rotatably connected to the other end of the adjusting rod 3. It should be understood that when the drive handle 4 is rotated clockwise (to... Figure 1 (For reference), the drive handle 4 will lower the adjusting rod 3, and at this time one end of the second clamping arm 2 will also rotate clockwise, so as to clamp the rod body 8.

[0030] The adjustment part 5 is located at the other end of the second clamping arm 2 and is used to adjust the length of the adjustment rod 3 extending relative to the other end of the second clamping arm 2.

[0031] The first locking part 6 is disposed between the first extension 12 and the bottom of the first clamping arm 1.

[0032] The rotating rod 7 is located below the first extension 12, and is rotatably connected to the other end of the drive handle 4. The top end of the rotating rod 7 is provided with a second locking part for engaging with the first locking part 6. It should be understood that when the second locking part on the rotating rod 7 is engaged with the first locking part 6, the size of the clamping jaws is fixed. When the second locking part disengages from the first locking part 6, the size of the clamping jaws can be readjusted.

[0033] In this embodiment, the first locking part 6 includes an extension rod 61 extending toward the drive handle 4. The bottom end of the extension rod 61 has multiple locking slots along its length. The second locking part includes a second extension 70 disposed at the top end of the rotating rod 7 and extending toward the first locking part 6, and a hook 71 for locking in the locking slots. The hook 71 is disposed at the top end of the second extension 70 away from the drive handle 4. It should be understood that since the rotating rod 7 is rotatably connected to the drive handle 4, when the rotating rod 7 rotates away from the extension rod 61 (i.e., counterclockwise), the hook 71 will not continue to hook into the multiple locking slots of the extension rod 61. However, when the rotating rod 7 is pushed toward the extension rod 61 (i.e., clockwise), the hook 71 can hook into the locking slots on the extension rod 61, thereby locking the rod body 8.

[0034] Preferably, the locking opening is serrated and tilted away from the drive handle 4, so that the hook 71 will not fall out when hooked in the locking opening. The hook 71 is triangular and the apex of the hook 71 is tilted towards the drive handle 4. This means that after the hook 71 hooks into the locking opening, the hook 71 will move backward, so that the second locking part of the rotating rod 7 is firmly hooked into the locking opening of the first locking part 6.

[0035] Preferably, the extension rod 61 is in the shape of an elongated arc.

[0036] Furthermore, the first locking part 6 also includes a fixing rod 62 integrally formed with the extension rod 61, wherein one end of the fixing rod 62 is fixedly disposed on the first extension part 12, the other end of the fixing rod 62 is fixedly disposed on the bottom of the first clamping arm 1, and one end of the extension rod 61 is fixedly disposed in the middle of the fixing rod 62.

[0037] Furthermore, the top of the rotating rod 7 is provided with a third extension 72 that is away from the first locking part 6, wherein the third extension 72 is rotatably connected to the other end of the drive handle 4.

[0038] Specifically, the third extension 72 is provided with an opening, and the other end of the drive handle 4 is provided with a rotating shaft 41 that passes through the opening.

[0039] Furthermore, the third extension 72 is also provided with an extension bar 73, and the extension bar 73, the third extension 72 and the rotating rod 7 form a slot, while the other end of the drive handle 4 is also provided with a locking rod 42 that is locked in the slot.

[0040] It can be understood that the rotating rod 7 houses the rotating shaft 41 through the opening of the third extension 72, so that the rotating rod 7 can rotate around the rotating shaft 41, while the locking rod 42 can lock the rotating rod 7 to prevent the rotating rod 7 from falling off.

[0041] Furthermore, the other end of the drive handle 4 is also equipped with a compression spring that compresses the bottom end of the rotating rod 7 so that it rotates toward the first locking part 6. It should be understood that one end of the compression spring supports the rotating rod 7, and the other end of the compression spring is set at the other end of the drive handle 4, so that under normal circumstances (i.e. when the handle is released), the compression spring compresses the bottom end of the rotating rod 7 to rotate toward the first locking part 6 (i.e., clockwise rotation), so that the hook 71 can be stably locked in the locking slot. Only when the bottom end of the rotating rod 7 is manually pressed can the hook 71 quickly disengage from the locking slot, so that the clamping device that originally required two hands to operate can be used with only one hand, and quick disassembly can be achieved.

[0042] In this embodiment, the adjustment part 5 includes a fixing member 51 and a rotating member 52 fixedly disposed on the other end of the second clamping arm 2. The fixing member 51 is provided with a through hole, and the adjustment rod 3 passes through the through hole. One end of the adjustment rod 3 is provided with an external thread along its length direction. The rotating member 52 is provided with a threaded hole that is threadedly connected to the external thread, so that the length of the adjustment rod 3 extending relative to the other end of the second clamping arm 2 can be adjusted by rotating the rotating member 52.

[0043] Specific working principle:

[0044] First, the first clamping arm 1 and the second clamping arm 2 are clamped onto the rod body 8. While pressing the rotating rod 7 (at this time, the hook 71 disengages from the locking slot), the driving rod 4 is also squeezed to rotate clockwise. As the driving rod 4 rotates clockwise, it will drive the other end of the second clamping arm 2 to rotate downward, causing one end of the second clamping arm 2 to rotate upward, thus tightly clamping the rod body 8. Then, the rotating rod 7 is released. At this time, the compression spring will squeeze the rotating rod 7 to rotate clockwise, thereby causing the hook 71 on the second extension 70 to lock into the locking slot, thus achieving locking. When disassembly is required, while holding the driving rod 4 with one hand, simply squeeze the rotating rod 7 to rotate counterclockwise to disengage the hook 71 from the locking slot. At this time, the driving rod 4 can rotate, causing one end of the second clamping arm 2 to release the rod body 8, thus achieving quick disassembly.
