[0002] Steel structure flexible waterproof roof system is a roof system commonly used in industrial and commercial buildings. It has the characteristics of lightness, durability and waterproofness.

[0003] The laying of steel structure flexible waterproof roof usually requires the use of a lot of installation equipment. Since the steel structure flexible waterproof roof is a high-altitude operation, it is not easy for the installers to reach the installation site, and it is not convenient to run back and forth between the steel structure flexible waterproof roof and the ground.

[0004] In order to avoid running around, you need to carry the necessary tools when you arrive at the steel structure flexible waterproof roof. Among the common installation equipment, in addition to some special installation equipment, common installation equipment such as wrenches also need to be carried. Due to the different sizes of wrenches, it is also necessary to carry a variety of wrenches of different specifications, which will increase the burden on the installers. When this ordinary wrench is rotated, the head of the hexagonal nut is equipped with a set of left and right clips. Due to the existence of the above-mentioned opening part, the head of the hexagonal nut is easily separated from the set of left and right clips, resulting in poor rotation operability.

[0076] A plurality of limit grooves are provided on the inner wall of the rotating sleeve 5;

[0077] The rotating sleeve 5 is slidably connected with a mounting tube 28, the mounting tube 28 is fixedly connected with a water storage tube 29, the water storage tube 29 is fixedly connected with two auxiliary tubes 32, the auxiliary tube 32 is slidably connected with an insertion rod 27, the insertion rod 27 is plugged with the auxiliary tube 32, the two insertion rods 27 are connected by a second spring 30, the second spring 30 is provided with a second slide bar 31, the second slide bar 31 is slidably connected with the auxiliary tube 32;

[0078] An extrusion plate 33 is slidably connected inside the water storage pipe 29 , and a press-rebound assembly is fixedly connected to the pressure plate. The press-rebound assembly passes through the mounting pipe 28 and is fixedly connected to the mounting pipe 28 .

[0079] The driving ring 1 is rotated, and the driving ring 1 drives the latching teeth 8 to act on the first gear 3. The rotation of the first gear 3 drives the mounting tube 28 to rotate through the connecting rod 16. Due to the action of the latching teeth 8, the first gear 3 will also move during the movement of the first gear 3, so that the mounting tube 28 will also drive the friction plate 36 to move, so that the spacing between the multiple friction plates 36 can be effectively adjusted, so that it can be suitable for different external hexagonal bolts;

[0080] By providing the handles 2 in different styles, it is convenient for the user to hold the device.

[0081] Embodiment 3:

[0082] like Figure 1-8 As shown, when other parts are the same as those of the embodiment 1, the difference between this embodiment and the embodiment 1 is that: the press-rebound assembly includes a fixing tube 35, and the fixing tube 35 is fixedly connected to the mounting tube 28;

[0088] By pressing the driving member 39, the driving member 39 drives the pressure rod 34 to move, and the pressure rod 34 drives the slider 42 to move. The slider 42 rotates the rotating plate 41 due to the track groove 38, so that the limit of the slider 42 is cancelled, and the slider 42 can move;

[0089] When the slider 42 is close to the water storage pipe 29, the squeezing plate 33 will squeeze the water source, so that the insertion rod 27 is plugged into the limiting groove by the water pressure to complete the limiting. When the slider 42 is away from the water storage pipe 29, the limiting is cancelled.

[0090] When the insertion rod 27 is plugged into the limiting groove, the drive ring 1 rotates, and the first gear 3 will not move, so that the friction plate 36 can only rotate. In this way, with the help of the rotating friction plate 36, some parts can be simply polished, for example, deburring, etc., so that the parts that were originally unusable can continue to be used.

[0091] Embodiment 4:

[0092] like Figure 1-8 As shown, when other parts are the same as those of the embodiment 1, the difference between this embodiment and the embodiment 1 is that: the driving mechanism includes a connecting rod 16, the connecting rod 16 is fixedly connected to the fixing tube 35, and the connecting rod 16 is slidably connected to the fixing ring 4;

[0097] The mounting frame 11 is slidably connected to a first slide bar 13 , the first slide bar 13 is fixedly connected to a connecting frame 20 , the connecting frame 20 is connected to the mounting frame 11 via a first spring 12 , the connecting frame 20 is fixedly connected to a rack 19 , and the rack 19 meshes with a second gear 21 .

[0098] The handle 2 is fixedly connected to the fixing ring 4 .

[0099] By continuously rotating the driving ring 1, the first gear 3 is continuously moved. After the first gear 3 moves to the specified position, it will act on the rack 19, and the rack 19 will act on the second gear 21. The second gear 21 will drive the second rotating shaft 26 to rotate through the action of the toggle piece 24. The second rotating shaft 26 rotates the reciprocating screw 14 through the first bevel gear 17 and the second bevel gear 18, so that the threaded plate 15 will move, so that the stored lubricating oil can be sprayed from the nozzle 10, and the spraying position is just located on the first gear 3, which is convenient for lubrication during the movement;

[0100] After the first gear 3 moves away, it can return to its original state due to the action of the first spring 12.

[0101] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
