DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The inner top wall of the frame 1 is provided with a clamping member 5;

[0025] The clamping member 5 includes a driving block 51 whose one end is threadedly connected to the outer side of the adjusting screw 4, the upper end of the driving block 51 is fixedly connected to a sliding block 52 whose end passes through the frame 1, the upper end of the sliding block 52 is fixedly connected to a supporting block 53, the outer side of the support block 53 is slidably connected to a supporting column 59, the upper end of the supporting column 59 is rotatably connected to a supporting frame 55, the inner side of the supporting frame 55 is fixedly connected to a placing block 58, the upper end of the supporting frame 55 is threadedly connected to a fixing screw 57 whose end passes through the supporting frame 55, the lower end of the fixing screw 57 is rotatably connected to a clamping block 56, and the lower end of the supporting frame 55 is fixedly connected to a rotating sleeve 54 located on the outer side of the supporting column 59.

[0026] In this embodiment, the started dual-axis motor 3 can drive the driving block 51 to move horizontally through the adjusting screw 4, and the support column 59 can slide back and forth on the support block 53, and the support frame 55 can rotate horizontally on the support column 59, so that curved pipes of different shapes can be clamped and fixed, such as "C"-shaped, "L"-shaped or "U"-shaped curved pipes, and because the rotating fixing screw 57 can drive the clamping block 56 to approach or move away from the placement block 58, curved pipes of different thicknesses can be clamped.

[0027] Among them, a first threaded hole located on the outside of the adjusting screw 4 is opened inside the driving block 51, and the first threaded hole cooperates with the thread on the outside of the adjusting screw 4, so that the adjusting screw 4 rotating forward or reverse can drive the driving block 51 to move horizontally for adjustment.

[0028] In addition, the support column 59 is convex-shaped, and a support groove located outside the support block 53 is opened at the lower end of the support column 59. The support groove and the support block 53 are both T-shaped, so that the support column 59 can slide back and forth stably on the support block 53.

[0029] Secondly, a connecting hole is provided on the inner top wall of the frame 1 and is located outside the sliding block 52. The front and rear sides of the sliding block 52 are both convex-shaped, and the side of the connecting hole close to the sliding block 52 is concave-shaped and is slidably connected to the convex end of the sliding block 52, so that the sliding block 52 can slide stably horizontally in the connecting hole without being separated from the connecting hole.

[0030] Then, a second threaded hole is opened on the inner top wall of the support frame 55 and is located on the outside of the fixing screw 57. The second threaded hole cooperates with the thread on the outside of the fixing screw 57 so that the fixing screw 57 can be moved longitudinally and adjusted on the inner top wall of the support frame 55 in a forward or reverse rotation.

[0031] Finally, the clamping block 56 is in the shape of a "X", and connection holes are opened on one side and the other side of the clamping block 56 and are located outside the support frame 55, so that the rotating fixing screw 57 can drive the clamping block 56 to move stably up and down on the support frame 55, and a placement groove is opened on the upper end of the placement block 58, and the placement groove is semicircular.

[0032] See also Figure 2 In this embodiment, the limiting member includes a pull rod 511 with one end passing through the support column 59 and extending to the inside of the support block 53, a stopper 510 is fixedly connected to the outer side of the pull rod 511, and a spring 512 is fixedly connected between the stopper 510 and the support column 59.

[0033] In this embodiment, by pulling the pull rod 511 to separate the rotating sleeve 54, the support frame 55 can be held and rotated horizontally on the support column 59 to change the orientation of the clamping block 56 and the placement block 58 on one side. When the pull rod 511 is continued to be pulled to separate the support block 53, the support frame 55 can be held and driven by the support column 59 to slide back and forth on the support block 53 to adjust the front and rear clamping orientation of the clamping block 56 and the placement block 58.

[0034] A number of limit grooves are provided on the outer side of the support block 53, and the limit grooves are equidistantly distributed front to back. The pull rod 511 is U-shaped, and the other end of the pull rod 511 extends to the inside of the rotating sleeve 54. A number of fixed grooves are provided on the outer side of the rotating sleeve 54, and the fixed grooves are equidistantly distributed in a ring shape on the outer side of the rotating sleeve 54. The specifications of the fixed grooves and the limit grooves are compatible with the specifications of the pull rod 511, so that the pull rod 511 extending into the rotating sleeve 54 and the support block 53 respectively can respectively limit the support column 59 sliding forward and backward and the rotating sleeve 54 rotating.

[0035] The working principle of the above embodiment is:

[0036] When the double-axis motor 3 is started, the driving block 51 can be driven to move horizontally by adjusting the screw 4. After the adjustment, when the pull rod 511 is pulled to rotate the sleeve 54 to separate, the support frame 55 can be held and rotated horizontally on the support column 59 to change the orientation of the clamping block 56 and the placement block 58 on one side. When the pull rod 511 is continued to be pulled to separate from the support block 53, the support frame 55 on one side can be held and driven to slide the support column 59 back and forth on the support block 53 to adjust the front and back clamping orientation of the clamping block 56 and the placement block 58. Therefore, the support frame 55 can be rotated horizontally on the support column 59 and move back and forth at the same time. Therefore, it can clamp and fix curved pipes of different shapes, such as "C"-shaped, "L"-shaped or "U"-shaped curved pipes. Moreover, since the rotating fixing screw 57 can drive the clamping block 56 to approach or move away from the placement block 58, it can clamp curved pipes of different thicknesses, thereby improving the practicality and adaptability of the entire clamp.
