At the same time, the moving plate drives the insertion rod to disengage from one of the slots on the surface of the hinge block;

[0032] Then, the mounting plate drives the hinge block to rotate 90 degrees with the hinge point of the hinge block as the axis, so that the mounting plate and the telescopic rod rotate from a mutually parallel state to a mutually perpendicular state, and then the two support plates drive the two connecting shafts to rotate as the axis, so that the two support rods are unfolded and the angles of the positioning grooves at the tops of the two connecting shafts match the angles of the two positioning blocks;

[0085] The number of the third movable grooves 433 is set to two, and the two third movable grooves 433 are respectively opened on both sides of the bottom of the slide groove 421, and the tops of the two third movable grooves 433 are connected to the slide groove 421, and the inside of the two third movable grooves 433 are slidably provided with a support rod 4312, and the bottom ends of the two support rods 4312 are fixedly connected with a positioning block 4313, and the two positioning blocks 4313 correspond to the two positioning grooves 439 respectively.

[0086] The working principle and use process of the present invention:

[0087] In the initial state, the squeezing spring 428 squeezes and drives the moving plate 425 to move to the bottom of the slide slot 421. At this time, the moving plate 425 drives the second rack 429 to move downward through the connecting rod 427. At the same time, the second rack 429 drives the two second gears 4211 to rotate, and then the two second gears 4211 respectively drive the two eccentric wheels 4212 to rotate through the two rotating rods 4210. At the same time, the friction rings 4213 on the outer peripheries of the two eccentric wheels 4212 squeeze the inner wall of the fixed sleeve rod 14, so that the friction force The telescopic rod 41 is fixed to the fixed sleeve rod 14, and by pulling the pull rod 426 upward, the movable plate 425 can be driven to move upward. The above structure can drive the two eccentric wheels 4212 to rotate in the opposite direction, so that the friction ring 4213 on the outer periphery of the two eccentric wheels 4212 is separated from the inner wall of the fixed sleeve rod 14. At this time, the telescopic length of the telescopic rod 41 relative to the fixed sleeve rod 14 can be adjusted, so that the placement height of the device can be adjusted. After the pull rod 426 is released, the telescopic rod 41 and the fixed sleeve rod 14 will be locked again through the above structure.

[0088] When the device needs to be supported later, the pull rod 426 is first pulled upward by the pull rod 426, so that the pull rod 426 drives the moving plate 425 to move upward, and the moving plate 425 drives the plug rod 4311 to move upward, and the moving plate 425 squeezes and compresses the squeezing spring 428, and at the same time, the moving plate 425 drives the plug rod 4311 to disengage from one of the slots 435 on the surface of the hinge block 434;

[0089] Then, the mounting plate 436 drives the hinge block 434 to rotate 90 degrees with the hinge point of the hinge block 434 as the axis, so that the mounting plate 436 and the telescopic rod 41 rotate from a mutually parallel state to a mutually perpendicular state, and then the two support plates 4310 drive the two connecting shafts 438 to rotate as the axis, so that the two support rods are unfolded and the angles of the positioning grooves 439 at the tops of the two connecting shafts 438 match the angles of the two positioning blocks 4313;

[0090] After that, the pull rod 426 is released. At this time, the movable plate 425 can be driven to move downward by squeezing the spring 428 to rebound. At the same time, the movable plate 425 will drive the insertion rod 4311 to move downward and make the insertion rod 4311 plug into another slot 435 on the surface of the hinge block 434, so as to fix the rotated hinge block 434, and then fix the mounting plate 436 fixedly connected to the hinge block 434. When the movable plate 425 moves downward, the movable plate 425 will drive the positioning blocks 4313 at the bottom of the two support rods 4312 to move downward, so that the two positioning blocks 4313 are respectively plugged into the positioning grooves 439 at the tops of the two connecting shafts 438, so as to lock the connecting shafts 438 so that the two connecting shafts 438 cannot rotate, and then fix the support plate 4310 fixed to the two connecting shafts 438, so that the device can be supported by the two support plates 4310;

[0091] When the moving frame 212 is at the bottom of the supporting bin 1, by pressing the pressing plate 217, the limit block 218 can be driven to move through the sliding rod 215. At this time, the limit block 218 will squeeze and compress the return spring 219, and at the same time, the limit block 218 will be disengaged from one of the limit grooves 213. Then, by pulling the pressing plate 217, the moving frame 212 can be driven to slide upward in the supporting bin 1 through the sliding rod 215 and the first fixing member 214 until the position of the limit block 218 corresponds to the position of the other limit groove 213. At this time, the limit block 218 can be driven to engage with the other limit groove 213 through the rebound of the return spring 219, so that the sliding rod 215 and the first fixing member 214 can be limited, and then the moving frame 212 can be limited, so that the moving frame 212 is fixed to the top of the supporting bin 1.

[0092] When the moving frame 212 moves upward, the extension bin 12 can rotate 90 degrees with the first rotating shaft 223 as the axis, so that the extension bin 12 and the supporting bin 1 are perpendicular to each other. During this process, the first gears 225 at both ends of the first rotating shaft 223 will move relative to the two first racks 221, and be driven to rotate by the two first racks 221, thereby driving the second rotating shaft 224 to rotate. At the same time, the second rotating shaft 224 will drive the first transmission wheel 226 to rotate, and the first transmission wheel 226 will drive the second transmission wheel 227 and the second rotating shaft 224 to rotate through the transmission belt 228. At the same time, the second rotating shaft 224 will drive the winding wheel 229 to rotate and unwind the hanging rope 2210, so as to hang the lead pendant 13;

[0093] When the plumb bob 13 is hanging, the plumb bob 13 will drive the plumb line to point vertically to the placement surface, and the measuring plate 31 will deflect relative to the inclination angle of the placement surface. When the measuring plate 31 deflects relative to the plumb line, the positioning member 34 limited by the plumb line will not move, and the two measuring plates 31 will move relative to the positioning member 34 during deflection, and the scale lines 33 on their surfaces will deflect relative to the two pointers 36 of the positioning member 34. By observing the position where the pointers 36 point to the scale lines 33, the deflection angle of the support surface where the device is placed can be known.

[0094] When it is necessary to store the extension bin 12 and reel in the lead sinker 13, it is necessary to move the moving frame 212 from the top to the bottom in the support bin 1. During this process, the extension bin 12 is rotated 90 degrees in the opposite direction with the first rotating shaft 223 as the axis, so that the extension bin 12 and the support bin 1 are coaxially distributed. After that, when the moving frame 212 moves from the top to the bottom in the support bin 1, the extension bin 12 can be inserted into the extension bin 12 through the first rotating shaft 223. During this process, the first teeth at both ends of the first rotating shaft 223 are The wheel 225 moves in the opposite direction relative to the two first racks 221, and is driven by the two first racks 221 to rotate in the opposite direction, thereby driving the second rotating shaft 224 to rotate in the opposite direction, and the second rotating shaft 224 drives the first transmission wheel 226 to rotate in the opposite direction, and the first transmission wheel 226 drives the second transmission wheel 227 and the second rotating shaft 224 to rotate in the opposite direction through the transmission belt 228, and the second rotating shaft 224 drives the winding wheel 229 to rotate in the opposite direction and wind up the hanging rope 2210, thereby storing the lead pendant 13;

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
