[0039] The specific configuration and functions of the fixing unit 3 and the taking unit 4 are described in detail below.

[0040] like Figure 1 and Figure 4 As shown, the fixing unit 3 includes a moving block 31, a fixing rod 32, a fixing block 33, a positioning member 34, a control block 35 and a clamping block 36, wherein the upper end surface of the fixing block 33 is provided with a first semicircular arc groove; the two ends of the lower end of the fixing block 33 are respectively provided with first convex plates, and each first convex plate is provided with a fixing rod 32.

[0041] A moving block 31 is disposed above the fixed block 33 . A second semi-circular arc groove is formed on the lower end surface of the moving block 31 . The second semi-circular arc groove is butt-jointed with the first semi-circular arc groove to form a circular hole structure.

[0042] The two ends of the upper end of the moving block 31 are respectively provided with second convex plates, each of which is provided with a through hole, and the two through holes are respectively sleeved on the two fixing rods 32 , and move up and down along the axis of the fixing rod 32 .

[0043] Two springs 37 are arranged between the fixed block 33 and the movable block 31 , and the two springs 37 are respectively sleeved on the two fixed rods 32 .

[0044] The upper end surface of the moving block 31 is provided with a positioning structure for limiting and fixing the moving block 31 .

[0045] The positioning structure includes a positioning member 34, a control block 35 and a clamping block 36, wherein the positioning member 34 is a cylindrical structure fixed to the upper end surface of the moving block 31; the control block 35 is a cylindrical structure with one end closed and the other end open, and the control block 35 is sleeved on the positioning member 34 and is rotatably connected to the positioning member 34.

[0046] Two inverted L-shaped clamps are symmetrically arranged on the side wall of the control block 35. The inverted L-shaped clamps are telescopic structures, that is, the vertical section is inserted into the free end of the horizontal section.

[0047] Two first connecting members are symmetrically arranged on the side wall of the positioning member 34 , two connecting rods are symmetrically arranged on each first connecting member, and a telescopic spring 38 is sleeved on each connecting rod.

[0048] The four connecting rods are placed between the two fixing rods 32 , and the axes of the four connecting rods and the axes of the fixing rods 32 are perpendicular to each other.

[0049] Two clamping blocks 36 are further disposed on the upper end surface of the moving block 31 . The upper end surface of the clamping block 36 is provided with an arc-shaped groove, which is matched with the fixing rod 32 .

[0050] Two second connecting members are symmetrically arranged on the side wall of the clamping block 36 , and the two second connecting members are respectively connected to two connecting rods.

[0051] A long groove is formed on the upper surface of each clamping block 36 , and the position of the long groove is symmetrical to the position of the arc-shaped groove.

[0052] The long groove cooperates with the inverted L-shaped clamp on the control block 35 to achieve position limiting and fixing of the clamp block 36 .

[0053] Working principle of fixed unit 3:

[0054] When it needs to be fixed, the movable block 31 is pushed toward the side close to the fixed block 33, and the compression spring is deformed under force to generate elastic force. When it moves to a certain position, the control block 35 is rotated, and the inverted L-shaped clamp on the control block 35 disengages from the long groove on the clamping block 36. At this time, the control block 35 loses the restraint on the clamping block 36. At the same time, the telescopic spring releases the elastic force, pushing the clamping block 36 to move, so that the clamping block 36 is inserted into the groove opened on the fixed rod 32, and the fixed rod 32 can be fixed.

[0055] When it is necessary to open, the card block 36 is pulled toward the side close to the positioning member 34, and the telescopic spring is deformed under force to generate elastic force. When it moves to a certain position, the control block 35 is rotated so that the inverted L-shaped card of the control block 35 cooperates with the long card slot of the card block 36, and then the card block 36 loses its restraint on the fixed rod 32, and the compression spring releases the elastic force, pushing the movable block 31 toward the side away from the fixed block 33 to complete its opening. This solves the problem that most existing manufacturers need manual support for welding bent pipes. Long-term support can easily cause workers to become tired and cause shaking, resulting in welding errors during the welding process, causing users to incur a lot of economic losses.

[0056] like Figure 1 , Figure 5 and Figure 6 As shown, the taking unit 4 includes a moving plate 41, a control rod 42, a limit block 43, a pressure plate 44, a moving rod 45 and a sliding rod 46, wherein the moving plate 41 is a door-type structure, and both side walls of the moving plate 41 are provided with a through hole 4101.

[0057] A slide bar 46 is installed in each of the two through holes, and the two slide bars 46 are respectively installed on two side edges of the desktop 2 in a symmetrical arrangement.

[0058] Bosses 4102 are installed on both side walls of the movable plate 41 .

[0059] The movable plate 41 is provided with two limit blocks 43 , which are symmetrically arranged on the upper end surface of the movable plate 41 .

[0060] A third semicircular groove is formed at one end of the limit block 43, and a U-shaped convex plate is provided at the other end; two mounting plates are also provided on the limit block 43, and the two mounting plates are placed close to one end of the U-shaped convex plate and are symmetrically arranged with the U-shaped convex plate as the center.

[0061] Each mounting plate is provided with a mounting hole.

[0062] The second semicircular arc grooves of the two limiting blocks 43 are butt-jointed and spliced ​​to form a circular hole structure.

[0063] A pressing plate 44 is placed on each U-shaped convex plate, and two matching holes are provided on the pressing plate 44; both ends of the pressing plate are bent hooks.

[0064] Each pressing plate 44 is also connected to a control rod 42 of a door-shaped structure. Both ends of the control rod 42 are slot structures, which cooperate with the bent member of the pressing plate 44 to achieve the connection between the pressing plate 44 and the control rod 42.

[0065] A moving rod 45 is mounted on the upper end surface of each pressing plate 44 . The moving rod 45 is a door-shaped structure. Two side rods of the moving rod 45 are respectively assembled in two matching holes opened on the pressing plate 44 .

[0066] The two side rods of the moving rod 45 are both sleeved with limit springs, and the limit springs are placed above the pressure plate 44 .

[0067] The movable plate 41 is also provided with a driving member for driving the limiting block 43 to move back and forth. Two driving members are provided and are symmetrically arranged on the upper surface of the movable plate 41 .

[0068] The driving member includes two fixed bases 48 , which are symmetrically arranged on both sides of the limiting block 43 and are placed on one side of the third semicircular arc groove on the limiting block 43 .

[0069] A center rod is fixed at the center of each fixed base 48; and a positioning spring 49 is sleeved on each center rod.

[0070] The free ends of the two center rods are respectively assembled in two mounting holes opened on the mounting plate provided on the limiting block 43 .

[0071] A limiting rod 47 is rotatably mounted at both ends of each sliding rod 46 , and the free end of the limiting rod 47 is a bent structure; the bent structure cooperates with the boss 4102 on the moving plate 41 to limit the moving plate 41 .

[0072] The working principle of the taking unit 4 is as follows:

[0073] When the device needs to be used, the control rod 42 is rotated, and then the control rod 42 loses the restraint on the pressure plate 44, and the limit spring releases the elastic force, pulling the pressure plate 44 to move, so that the pressure plate 44 loses the restraint on the limit block 43;

[0074] At this time, the positioning spring releases its elastic force and pulls the limit block 43 to one side so that the limit block 43 clamps the object. Then the limit rod 47 is rotated so that the limit rod 47 loses its restraint on the movable plate 41, and the movable plate 41 is slid to one side to complete the removal of the object.

[0075] When the object needs to be taken out, the limit block 43 is pulled to one side, and the positioning spring is deformed by force to generate elastic force. When it moves to a certain position, the pressure plate 44 is pressed downward, and the limit spring is deformed by force to generate elastic force. When the pressure plate 44 is inserted into the limit block 43, the control rod 42 is rotated so that the control rod 42 and the pressure plate 44 are abutted, and the object can be taken out. The movable plate 41 is moved to one side. When it moves to the initial position, the limit rod 47 is rotated so that the limit rod 47 and the movable plate 41 are abutted, and the object can be closed.

[0076] The invention solves the problem that most of the existing manufacturers need to manually remove the bent pipes after welding. Due to the high welding temperature, the local temperature of the bent pipes is too high, and workers are prone to burn their skin when removing them, which causes certain safety hazards in the processing of materials.

[0077] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
