Guide slide bars 5 are respectively connected through the inner corners on both sides of the first base 1. A ball screw 7 is rotatably mounted on one side of the first base 1. A transmission gear ring 71 is rotatably mounted on the inner wall of the device groove 4 outside the first base 1 and the second base 2. A transmission gear 73 and a second bevel gear 75 are respectively rotatably mounted on the circumferential surface of the device groove 4. A first bevel gear 74 is installed on one side of the transmission gear 73. A worm gear mechanism 8 is arranged on the side of the first base 1 away from the first base 1, and the worm gear mechanism 8 includes a worm 81 which is vertically rotatably mounted. A worm gear 83 is fixedly sleeved on one end of the ball screw 7 close to the worm gear mechanism 8. A spline shaft 9 and a spline sleeve 91 are rotatably mounted on one side of the bottom of the inner wall of the groove 4 outside the first base 1 and the second base 2, respectively. Synchronous gears 92 are fixedly sleeved on the outside of the spline shaft 9 and the spline sleeve 91; In this embodiment, the two groups of bases 11 in the first base 1 can cooperate with the mold base 31 through the half locking module 3 to quickly lock and form, and the worm 81 in the worm gear mechanism 8 drives the worm wheel 83, so that the ball screw 7 can rotate, so that the second base 2 can slide closer along the guide slide rod 5, and at the same time, the ball screw 7 is close to the transmission gear 73 on the first base 1 and meshes with the transmission gear ring 71 to rotate synchronously, and the multiple groups of transmission gears 73 drive the second bevel gear 75 through the first bevel gear 74, so that the threaded rod 76 can rotate synchronously, thereby synchronously driving the chuck 77 in the through groove 41, and the stainless steel pipe in the first base 1 can be clamped and positioned. In this way, when the stainless steel pipe in the second base 2 is moved and docked, the stainless steel pipe in the first base 1 can be clamped and positioned synchronously; In this embodiment, the synchronous gear 92 on the spline sleeve 91 at the bottom of the first base 1 is synchronously driven through the transmission ring gear 71 on the device groove 4, so that the spline shaft 9 at one end of the spline sleeve 91 is synchronously driven, and under the transmission of the synchronous gear 92 on the spline shaft 9, the transmission ring gear 71 on the second base 2 is synchronously driven. Similarly, the chuck 77 on the second base 2 can be synchronously driven, so that the stainless steel pipe in the second base 2 can be clamped and positioned. In this way, when the steel pipe in the second base 2 is moved and docked, it can be clamped and positioned synchronously, thereby realizing fast and convenient docking of the stainless steel pipe.

[0020] Among them, the first base 1 includes two groups of symmetrical bases 11, and the two groups of bases 11 are symmetrically installed with Huff locking modules 3 on the outside. The Huff locking module 3 includes a mold base 31 fixedly installed on the side wall of the device groove 4. The Huff locking module 3 is locked and fixed by the mold base 31. The two groups of bases 11 in the first base 1 can cooperate with the mold base 31 through the Huff locking module 3 to be quickly locked and formed.

[0021] Among them, the other end of the guide slide rod 5 is movable and penetrates to one side of the second base 2, and the ball screw 7 is connected with one side of the external device groove 4 of the second base 2 through a thread.

In this way, after the stainless steel pipes are connected in pairs, the fixed sleeve 6 and the movable sleeve 61 can simultaneously connect and wrap the connection between the steel pipes, thereby protecting the connection between the stainless steel pipes.

[0022] Among them, mounting seats 72 are fixedly installed on the inner side walls of the external device grooves 4 of the first base 1 and the second base 2 at equal intervals, and the transmission gear 73 is rotatably installed in the inner wall of the mounting seat 72 through the rotating shaft.

The worm 81 in the worm gear mechanism 8 drives the worm wheel 83, so that the ball screw 7 can rotate, so that the second base 2 can slide closer along the guide slide bar 5. At the same time, the ball screw 7 is close to the transmission gear 73 on the first base 1 and meshes with the transmission gear ring 71 to rotate synchronously.

[0023] Among them, through grooves 41 are opened on the inner side walls of the first base 1 and the second base 2 at equal intervals, and a threaded rod 76 is fixedly installed on the second bevel gear 75 near the side of the through groove 41.

The top of the chuck 77 is a square tube structure, and the chuck 77 is threadedly connected to the top threaded rod 76 through the top square tube. The transmission gear 73 on the ball screw 7 near the first base 1 engages with the transmission gear ring 71 and rotates synchronously. Multiple sets of transmission gears 73 transmit the second bevel gear 75 through the first bevel gear 74, so that the threaded rod 76 can rotate synchronously, thereby synchronously transmitting the chuck 77 in the through groove 41, and can clamp and position the stainless steel pipe in the first base 1. In this way, when the stainless steel pipe in the second base 2 is moved and docked, the stainless steel pipe in the first base 1 can be clamped and positioned synchronously.

[0024] Among them, the end of the ball screw 7 away from the first base 1 movably passes through another set of mounting seats 72, a transmission gear 73, and a first bevel gear 74. The worm gear mechanism 8 also includes a mounting plate fixedly mounted on one side of the first base 1. The worm 81 is rotatably mounted on the inner wall of the mounting plate through a rotating shaft, and a flange 82 is fixedly mounted on the top rotating shaft of the worm 81. The outer edge of the worm 81 is meshed with the outer edge of the worm wheel 83. One end of the spline shaft 9 movably passes through the fixed sleeve 6 and the movable sleeve 61. The outer extension of the spline shaft 9 is meshed with the inside of the spline sleeve 91. The two sets of synchronous gears 92 are respectively connected to the transmission gear ring on the same side. The outer edges of 71 are meshed, and the synchronous gear 92 on the spline sleeve 91 at the bottom of the first base 1 is synchronously driven through the transmission ring gear 71 on the device groove 4, so that the spline shaft 9 at one end of the spline sleeve 91 is synchronously driven, and under the transmission of the synchronous gear 92 on the spline shaft 9, the transmission ring gear 71 on the second base 2 is synchronously driven. Similarly, the chuck 77 on the second base 2 can be synchronously driven, so that the stainless steel pipe in the second base 2 can be clamped and positioned. In this way, when the steel pipe in the second base 2 is moved and docked, it can be clamped and positioned synchronously, and the stainless steel pipe docking is fast and convenient.

[0025] Working principle: When in use, the two sets of bases 11 in the first base 1 can be matched with the mold base 31 through the half locking module 3 to quickly lock and form; Then, the first base 1 and the second base 2 are respectively sleeved on the docking stainless steel pipe, and the worm 81 in the worm gear mechanism 8 drives the worm wheel 83, so that the ball screw 7 can rotate, so that the second base 2 can slide closer along the guide slide rod 5, and at the same time, the ball screw 7 is close to the transmission gear 73 on the first base 1 and meshes with the transmission gear ring 71 to rotate synchronously, and the multiple sets of transmission gears 73 drive the second bevel gear 75 through the first bevel gear 74, so that the threaded rod 76 can rotate synchronously, thereby synchronously driving the chuck 77 in the through groove 41, and the stainless steel pipe in the first base 1 can be clamped and positioned. In this way, when the stainless steel pipe in the second base 2 is moved and docked, the stainless steel pipe in the first base 1 can be clamped and positioned synchronously; The synchronous gear 92 on the spline sleeve 91 at the bottom of the first base 1 is synchronously driven through the transmission ring gear 71 on the device groove 4, so that the spline shaft 9 at one end of the spline sleeve 91 is synchronously driven, and under the transmission of the synchronous gear 92 on the spline shaft 9, the transmission ring gear 71 on the second base 2 is synchronously driven. Similarly, the chuck 77 on the second base 2 can be synchronously driven, so that the stainless steel pipe in the second base 2 can be clamped and positioned. In this way, when the steel pipe in the second base 2 is moved and docked, it can be clamped and positioned synchronously, realizing fast and convenient docking of the stainless steel pipe.
