As shown in fig. 1-3, an adjustable clamp is further provided in the present embodiment, which includes a fixing base 1 having a first clamping portion 101, a sliding base 2 slidably mounted on the fixing base 1 and having a second clamping portion 201, a locking member 3 rotatably mounted on the fixing base 1, and an elastic member 4 disposed between the locking member 3 and the fixing base 1; the first clamping part 101 is arranged opposite to the second clamping part 201; the sliding seat 2 is provided with a first positioning tooth 202, and the locking member 3 is provided with a second positioning tooth 301 engaged with the first positioning tooth 202.

In the embodiment of the present application, referring to fig. 1-2 synchronously, the state of the adjustable clamp clamping and fixing the lamp and other objects is: the lamp (for example, a lamp rod) is clamped between the first clamping portion 101 and the second clamping portion 201, at this time, the second positioning teeth 301 on the locking member 3 are engaged with the first positioning teeth 202 on the sliding seat 2, and the elastic member 4 tightly presses the locking member 3, so that the locking member 3 cannot rotate, and therefore, the sliding seat 2 cannot slide relative to the fixed seat 1, and the lamp can be continuously clamped between the first clamping portion 101 and the second clamping portion 201.

The process of releasing the clamping state of the adjustable clamp on the lamp is as follows: the locking piece 3 is rotated, so that the second positioning teeth 301 on the locking piece 3 are separated from the first positioning teeth 202 on the sliding seat 2, at this time, the locking piece 3 does not affect the sliding of the sliding seat 2 relative to the fixed seat 1, force can be applied to the sliding seat 2 and the second clamping portion 201, the sliding seat 2 slides and drives the second clamping portion 201 to be away from the first clamping portion 101, and then clamping and fixing of the lamp are released.

The process of fixedly mounting the lamp on the adjustable clamp comprises the following steps: placing the lamp between the first clamping portion 101 and the second clamping portion 201, and applying a force to the first clamping portion 101 and the second clamping portion 201 (at this time, applying a force to the locking member 3 and rotating the locking member 3 to separate the second positioning teeth 301 on the locking member 3 from the first positioning teeth 202 on the sliding seat 2), so that the second clamping portion 201 drives the sliding seat 2 to slide in a direction close to the first clamping portion 101, and the lamp is clamped between the first clamping portion 101 and the second clamping portion 201; then, the force applied to the locking member 3 is released, and the elastic member 4 recovers and drives the locking member 3 to rotate in the opposite direction, so that the second positioning teeth 301 on the locking member 3 are inserted into the first positioning teeth 202 on the sliding seat 2, and the sliding seat 2 is fixed on the fixed seat 1. Therefore, the lamp is fixedly arranged on the adjustable clamp.

Also, the adjustable clamp provided by the embodiment of the application only needs to apply force to the locking piece 3 when installing and fixing articles such as a lamp, and drives the locking piece 3 to rotate by a certain angle, the sliding seat 2 slides, then external force is removed, and the elastic piece 4 drives the locking piece 3 to rotate reversely. When the lamp and other articles are disassembled, only force needs to be applied to the locking piece 3, the locking piece 3 is driven to rotate by a certain angle, and the sliding seat 2 is slid. Therefore, the installation, the fixation and the disassembly can be quickly finished through the locking piece 3, the operation convenience is improved, and the adjustable clamp can be used for quickly disassembling and assembling products such as lamps.
