[0035] The present invention will be described in further detail below with reference to the accompanying drawings.

[0036] A height-adjustable clamp includes a base 1, with a mounting base 2 fixedly connected to the upper end of the base 1; a slide 3 is provided on the front side of the mounting base 2, and a sliding mechanism 4 is provided at the front end of the mounting base 2. The sliding mechanism 4 includes a slide rail 41 and a slider 42. The two slide rails 41 are fixedly connected to the two sides of the front end of the mounting base 2, and the two sliders 42 are fixedly connected to the two ends of the rear side of the mounting base 2. The sliders 42 on both sides are respectively slidably connected to the slide rails 41 on both sides. The slide 3 can slide up and down on the slide rails 41 through the limitation of the two sliders 42.

[0037] A lifting mechanism 5 is provided on the mounting base 2. A pulley 51 is rotatably connected to the middle of the upper and lower ends of the front side of the mounting base 2. A belt 52 is sleeved between the upper and lower pulleys 51. A connecting base 53 is fixedly connected to one end of the rear side of the slide 3. The connecting base 53 is fixedly sleeved on one side of the belt 52. The lower end of the rear side of the mounting base 2 is fixedly connected to the motor 2 12. The rear end of the lower end pulley 51 is fixedly connected to the front end of the motor 2 12. The motor 2 12 drives the pulley 51 to rotate, thereby driving the belt 52 to rotate. The rotation of the belt 52 drives the connecting base 53 to move, thereby driving the slide 3 to move up and down.

[0038] A rotating mechanism 6 is provided on the slide 3, and the rotating mechanism 6 includes a motor 61 fixedly connected to the middle of the inner side of the slide 3. The front end of the motor 61 passes through the slide 3 and is fixedly connected to a rotating seat 62. The front end of the rotating seat 62 is fixedly connected to a fixed seat 7. A clamping mechanism 8 is provided on the fixed seat 7. The clamping mechanism 8 includes clamping arms 81 slidably connected to both sides of the front end of the fixed seat 7. The front sides of the upper and lower ends of the inner side of the fixed seat 7 are provided with sliding grooves 82 for cooperating with the clamping arms 81, and the side where the clamping arms 81 are close to each other is fixedly connected to an anti-slip pad 83; a transmission mechanism 9 is provided on the fixed seat 7, and the transmission mechanism 9 includes a limit seat 91 fixedly connected to the rear end of the clamping arm 81, and a trapezoidal block 92 is slidably connected between the limit seats 91 at both ends.

[0039] A limiting mechanism 10 is provided between the limiting seat 91 and the trapezoidal block 92. A cylinder 11 is fixedly connected to the middle of the rear end of the fixed seat 7. The front end of the cylinder 11 passes through the fixed seat 7 and is fixedly connected to the middle of the rear end of the trapezoidal block 92. The limiting mechanism 10 includes a T-shaped limiting block 101 and a slide 102. Two T-shaped limiting blocks 101 are fixedly connected to both sides of the trapezoidal block 92. The slide 102 is provided on the side of the limiting seat 91 that is close to each other to cooperate with the T-shaped limiting blocks 101. The limiting seat 91 is a right-angled trapezoidal frame structure, and the inclined surfaces of the limiting seats 91 at both ends are arranged close to each other.

[0040] When the utility model is implemented, Figure 1-6As shown, when in use, the cylinder 11 is started to move backward, and the cylinder 11 moves backward, driving the trapezoidal block 92 to move backward. The trapezoidal block 92 moves backward, driving the T-shaped limit blocks 101 on both sides to move, thereby driving the limit seats 91 on both sides to approach each other. The limit seats 91 approach each other and drive the clamping arms 81 on both sides to move closer to each other under the limit of the slide groove 82 to clamp the charger. The anti-slip pad 83 can prevent slipping. The clamping arms 81 approach each other from both sides of the fixed seat 7 to clamp the charger, so that the width of the front end of the fixed seat 7 does not need to exceed the width between the clamping arms 81 on both sides. Therefore, the clamping mechanism is more compact and convenient, and more flexible when used.

[0041] Then start motor 2 12 to drive pulley 51 to rotate clockwise, thereby driving belt 52 to rotate clockwise. The clockwise rotation of belt 52 drives the connecting seat 53 on the left to move upward, thereby driving the slide 3 to move upward, and moving the charger upward. Driven by the external moving mechanism, the base 1 can move left and right to move the charger to the appropriate position. When it needs to be put down, start motor 2 12 to rotate in the opposite direction, drive the slide 3 to move downward, and place the charger in the required position. Start cylinder 11 to move forward, which can drive the clamping arms 81 on both sides to move away from each other and release the clamping of the charger.

[0042] When the charger needs to be flipped over to change its position, it is only necessary to start the motor 61 to drive the rotating seat 62 to rotate. The rotating seat 62 rotates to drive the fixed seat 7 to rotate as a whole. The fixed seat 7 rotates as a whole to drive the clamping arm 81 and the clamped charger to rotate, thereby realizing the flipping of the charger.
