[0023] In this embodiment, a braking mechanism 8 is provided inside the adjusting box 3. By pulling the end of the support rod 86 through the hinged plate 87 in the braking mechanism 8, the two sliders 81 can drive the two arc-shaped clamping plates 83 at the ends of the connecting rod 82 to move toward each other to clamp the middle support column 2. By driving the arc-shaped clamping plate 83 to engage the locking teeth 84 into the tooth groove 85, the adjusting box 3 and the support column 2 can no longer rotate relative to each other, so that the angle of the workpiece is positioned for easy operation.

[0024] In this embodiment, a limiting mechanism 9 is provided on the braking mechanism 8. By engaging the clamping block 92 in the limiting mechanism 9 on the right side of the clamping groove 93, the clamping tooth 84 can be stably engaged in the tooth groove 85, so that the angle of the workpiece is stably engaged. At the same time, by pushing the elastic plate 91, the clamping block 92 is released from the limit, so that the angle of the workpiece can be readjusted.

[0025] The above-mentioned stopping mechanism 8 includes a slider 81, which is slidably connected to the inner wall of the adjustment box 3. A connecting rod 82 is fixedly installed on the outer wall of the slider 81. The connecting rod 82 is set in a bent shape. An arc-shaped clamping plate 83 is fixedly installed on the end of the connecting rod 82. A clamping tooth 84 is fixedly installed on the outer wall of the arc-shaped clamping plate 83. A tooth groove 85 is opened on the outer wall of the support column 2. The clamping tooth 84 is driven by the arc-shaped clamping plate 83 to engage with the inner part of the tooth groove 85, so that the adjustment box 3 and the support column 2 can no longer be moved. The relative rotation positions the angle of the workpiece. The tooth groove 85 is located between the two arc-shaped clamping plates 83. The two sliders 81 can drive the two arc-shaped clamping plates 83 at the ends of the connecting rod 82 to move toward each other to clamp the middle support column 2. The slider 81 is hinged to one end of the support rod 86. The other end of the support rod 86 is hinged to the hinge plate 87. The hinge plate 87 is fixedly installed on the end of the pull rod 6. The pull rod 6 drives the end hinge plate 87 to move to the right to pull the end of the support rod 86, so that the two sliders 81 can move toward each other.

[0026] The above-mentioned limiting mechanism 9 includes an elastic plate 91, which is fixedly mounted on the outer wall of the hinge plate 87, and a clamping block 92 is fixedly mounted on the outer wall of the elastic plate 91. By pushing the elastic plate 91, the clamping block 92 can be driven to release the limit, which is convenient for re-adjusting the angle of the workpiece. The upper end of the clamping block 92 is set to an arc shape, and the arc-shaped outer wall of the clamping block 92 is squeezed by the edge of the clamping groove 93, so that the clamping block 92 can drive the elastic plate 91 to bend downward so that the limit is released, which is convenient for clamping. A clamping groove 93 is opened on the side wall of the adjustment box 3, and the clamping groove 93 is located on the side of the clamping block 92. The elastic force of the elastic plate 91 can make the clamping block 92 clamped on the right side of the clamping groove 93, so that the clamping tooth 84 is stably clamped in the inside of the tooth groove 85.

[0027] In this embodiment, the workpiece is placed on the hook cable 5, and the angle of the workpiece on the hook cable 5 is adjusted by the rotation connection between the support column 2 and the adjustment box 3. When the angle of the tool needs to be positioned, the pull rod 6 is pulled toward the outer wall of the adjustment box 3, so that the pull rod 6 drives the end hinge plate 87 to move rightward to pull the end of the support rod 86, and then the two sliders 81 are hinged between the support rod 86 and the slider 81, so that the two sliders 81 move toward each other, and then the two sliders 81 drive the two arc-shaped clamping plates 83 at the ends of the connecting rod 82 to move toward each other to clamp the middle support column 2, and then the arc-shaped clamping plate 83 drives the clamping teeth 84 to clamp into the inside of the tooth groove 85, so that the adjustment box 3 and the support column 2 can no longer rotate relative to each other, and then The angle of the workpiece is positioned, and at the same time, the block 92 on the outer wall of the elastic plate 91 is driven to move toward the groove 93 through the hinge plate 87, and the arc-shaped outer wall of the block 92 is squeezed by the edge of the groove 93, so that the block 92 drives the elastic plate 91 to bend downward so that the limit is released, and then the block 92 moves out of the adjustment box 3, and the elastic force of the elastic plate 91 makes the block 92 clamped on the right side of the groove 93, so that the clamping tooth 84 is stably clamped in the tooth groove 85. When the angle of the workpiece needs to be readjusted, the limit is released by pushing the elastic plate 91, and then the two arc-shaped clamping plates 83 are reset by the elastic force of the bearing spring 7, and then the limit is released to facilitate the readjustment of the angle of the workpiece.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
