The first clamping member 6 includes a first clamping section 602, a first clamping section 601 and a first fastening section 603 that are integrally formed at both ends of the first clamping section 602, and a second clamping section 702, and a second fastening section 703 that are integrally formed at both ends of the second clamping section 702. A groove 9 is provided on the outer side of the first fastening section 603, and a silicone ring 10 is provided on the outer side of the second fastening section 703. The silicone ring 10 can be inserted into the groove 9 to quickly clamp the first clamping member 6 and the second clamping member 7. The clamping device can quickly clamp the first clamping member 6 and the second clamping member 7 by providing the silicone ring 10 and the groove 9. The silicone ring 10 is inserted into the groove 9 to quickly clamp the first clamping member 6 and the second clamping member 7, thereby saving a lot of operation time and achieving the purpose of rapid clamping. Moreover, the silicone ring 10 has excellent elasticity, so that the clamping device can fix cylindrical objects of different diameters.

[0027] The first clamping section 602 and the second clamping section 702 are both arc-shaped structures and their openings are arranged facing each other. In this way, the first clamping member 6 and the second clamping member 7 can form a fixed space for fixing cylindrical objects. The inner sides of the first clamping section 602 and the second clamping section 702 are both provided with rubber pads 11. By providing the rubber pads 11, the cylindrical objects can be fixed more stably and firmly. The first clamping section 601 and the second clamping section 701 are both annular clamps, and the annular clamps are provided with Ω grooves 8. In this way, the first clamping member 6 and the second clamping member 7 can be directly clamped on the bracket body through the Ω grooves 8, which is convenient for disassembly and replacement.

[0028] refer to Figure 2-4 The utility model also provides a bracket, including a bracket body and the above-mentioned clamping device, which is arranged on the bracket body. The cylindrical object supported by the bracket body can be quickly fixed by the clamping device to ensure the quality of spraying or painting. The bracket body includes supporting feet 1, which are provided with two groups and are arranged opposite to each other. Four connecting rods 2 arranged in a rectangular array are provided between the two groups of supporting feet 1. The outer part of the connecting rod 2 is provided with an NBR sleeve 3. The inner side surface of the NBR sleeve 3 is tightly fitted with the outer wall surface of the connecting rod 2. The NBR sleeve 3 includes two top-layer NBR sleeves 301 and two bottom-layer NBR sleeves 302. The supporting feet 1 are composed of an outer supporting plate 101 and an inner supporting plate 102 hinged to each other. The bracket body also includes an adjusting mechanism, which is used to adjust the spacing between the two top-layer NBR sleeves 301. The first clamping section 601 of the clamping device is provided between the top-layer NBR sleeve 301 and the outer supporting plate 101 and is connected to the connecting rod 2 for clamping and rotation. The second clamping section 701 of the clamping device is provided between the top-layer NBR sleeve 301 and the inner supporting plate 102 and is connected to the connecting rod 2 for clamping and rotation. When in use, the distance between the two top NBR sleeves 301 can be changed by operating the adjustment mechanism to support cylindrical objects of different diameters; then the cylindrical objects of different diameters placed on the two top NBR sleeves 301 are fixed by the clamping device. The bracket can support and quickly fix cylindrical objects of different diameters, and the fixing process is time-saving, labor-saving, fast and efficient.

[0029] In this embodiment, the NBR sleeve 3 is made of NBR material, which is nitrile rubber, and has the characteristics of anti-slip, elasticity and good viscosity. The NBR sleeve 3 has elasticity and viscosity, so placing a cylindrical object on the two top NBR sleeves 301 will not leave scratches on the outer surface of the cylindrical object, and can also increase the friction between the outer surface of the cylindrical object and the surface of the top NBR sleeve 301, making the fixation more stable; the NBR sleeve 3 has anti-slip properties, so the two bottom NBR sleeves 302 will not move and flip when in contact with the horizontal plane, and the structure is stable and firm.

Such an arrangement facilitates the clamping device to better fix the cylindrical objects placed on the two top NBR sleeves 301. The adjustment mechanism includes a clamping piece 4 that is arranged on both sides of the bottom NBR sleeve 302 in opposite directions. The clamping piece 4 is located between the bottom NBR sleeve 302 and the outer support piece 101 and is rotatably connected to the connecting rod 2. The clamping piece 4 is provided with a clamping groove 5 that is adapted to the connecting rod 2. By adjusting the clamping pieces 4 on both sides of the bottom NBR sleeve 302 at the same time, the connecting rod 2 is clamped into different clamping grooves 5, and the distance between the two top NBR sleeves 301 is also changed accordingly to support cylindrical objects of different diameters. The clamping groove 5 includes a first clamping groove 501, a second clamping groove 502 and a third clamping groove 503 that are sequentially arranged at the lower edge of the clamping piece 4. When the positioning pieces 4 on both sides of the bottom NBR sleeve 302 are adjusted at the same time, and the connecting rod 2 is respectively inserted into the first slot 501, the second slot 502 and the third slot 503, cylindrical objects with diameters of 80-110mm, 65-85mm and 45-55mm can be placed on the two top NBR sleeves 301 respectively. The outer support piece 101 and the inner support piece 102 are intersected and connected by the hinge shaft 12, and the width of the hinge shaft 12 matches the slot width of the slot 5. When the positioning pieces 4 on both sides are simultaneously retracted upward to make the hinge shaft 12 inserted into the slot 5, the bracket body can be folded up for easy storage and carrying.

[0031] The working principle of the utility model: when in use, first measure the diameter of the cylindrical object, which is 70 mm, and adjust the positioning pieces 4 on both sides of the bottom NBR sleeve 302 at the same time, so that the connecting rod 2 is inserted into the second slot 502, and then the cylindrical object is placed on the top NBR sleeve 301, and the first clamping piece 6 and the second clamping piece 7 are rotated and the silicone ring 10 is inserted into the groove 9, so that the first clamping piece 6 and the second clamping piece 7 can quickly fix the cylindrical object, and then the outer surface of the cylindrical object can be sprayed or painted. After spraying or painting, remove the silicone ring 10 from the groove 9, and quickly separate the first clamping piece 6 and the second clamping piece 7, remove the cylindrical object, and then simultaneously fold up the positioning pieces 4 on both sides of the bottom NBR sleeve 302, and insert the hinge shaft 12 into the third slot 503, and the bracket body can be folded up for easy storage and carrying.
