5 and 4 swing joint of basis piece, one side fixedly connected with mount 11 of basis piece 4, the both ends of mount 11 one side all run through and are provided with pipe fitting 7, the inside slidable mounting of pipe fitting 7 has movable rod 8, the one end fixedly connected with bayonet lock 9 of movable rod 8, the one end fixedly connected with bayonet lock 9 stretches out the inner chamber of pipe fitting 7, two 6 of special-shaped gear and two 12 looks of bayonet lock, the movable rod 10 and the movable rod cavity of bayonet lock are equipped with the inner wall of spring pipe fitting 10, the movable rod 10 and the movable rod chamber 10, the movable rod chamber 10 and spring chamber 10.

The specific using process is as follows: firstly, matching is carried out according to the angle of the on-site pipe fitting, if the bending angle of the elbow is matched with the angle of the pipe fitting, a user does not need to adjust and directly installs the pipe fitting, the installation mode is the prior art, the description is not excessive, if the angle of the on-site pipe fitting is larger than the angle of the elbow, the user can hold the first end 1 by one hand and hold the second end 2 by the other hand, the first end 1 is kept still, the user moves the second end 2 in the direction opposite to the first end 1, so the second end 2 is unfolded outwards, then the first connecting arm 13 and the second connecting arm 14 which are installed on the first end 1 and the second end 2 are moved along with the first connecting arm, meanwhile, the first special-shaped gear 6 and the second special-shaped gear 12 are respectively moved along with the second connecting arm 14 and the first connecting arm 13, it is required to say that the movement is the rotation of the rotating shaft pin 5 as the rotating axis, the same principle, the movement of the first end 1 and the second end 2 is also rotated by the rotating shaft pin 5 as the rotating shaft, then the special-shaped gear 6 and the special-shaped gear 12 are rotated along with the rotating shaft pin 5, the elbow, the angle of the elbow is increased, and the angle of the elbow is also reduced until the first end 2 is adjusted along with the second end 1, the elbow, so that the angle of the elbow is reduced, until the bending angle of the elbow is matched with the angle of the pipe fitting, the pipe fitting is installed, to sum up, by adopting the design that the bending angle of the elbow can be adjusted at any time according to the field situation, so that a user can adjust the bending angle of the elbow at any time according to the angle of the field pipe fitting in the field work, the currently prepared elbow can be installed in a matched manner, a new elbow does not need to be prepared again, a new elbow does not need to be produced again, the adaptation range of the elbow of the pipe fitting is expanded, convenience is provided for the installation work of the user, it needs to be noted that after the currently required angle is adjusted, the bayonet lock 9 can be inserted between two teeth on the gear, namely between two teeth on the special-shaped gear I6 and two teeth on the special-shaped gear II 12, the following is a general name of the gear, and the state is a non-working state, when the gear works, the gear rotates from the direction of the inclined plane 19, the teeth touch the inclined plane 19, then the bayonet lock 9 is jacked up to the inner cavity of the movable cavity 20, the bayonet lock 9 drives the movable rod 8 to slide in the inner cavity of the movable cavity 20, the movable rod 8 drives the rotating handle 16 to move on the outer side of the pipe fitting 7, wherein the bayonet lock 9 compresses the spring 10 when moving, when the bayonet lock 9 passes through one tooth, under the action of the spring 10, the bayonet lock 9 resets again and is clamped between two adjacent teeth again to position the gear, the bayonet lock is reciprocated in such a way, once positioning is carried out when the bayonet lock 9 passes through one tooth, thereby facilitating accurate control of angle adjustment of a user, and it needs to be noted that the telescopic pipe fitting 3 can be telescopic, the telescopic track of the telescopic pipe fitting is the same as the expansion tracks of the first end 1 and the second end 2, and the telescopic pipe fitting 3 is also sealed, therefore, the sealing performance of the integral end head 1, the integral end head 2 and the telescopic pipe fitting 3 is ensured, the sealing technology of the telescopic pipe fitting 3 is the prior art, which is not described in the specification, wherein the connecting technology of the end head 2 and the end head 1 and the pipe fitting is the prior art.

It should be noted that, when the first special-shaped gear 6 and the second special-shaped gear 12 are adjusted by rotating in opposite directions, the user can rotate the rotating handle 16 to drive the movable rod 8 to rotate, and then the inclined surface 19 will rotate, so that the orientation of the inclined surface 19 is opposite to the current orientation, and thus when the first special-shaped gear 6 and the second special-shaped gear 12 are adjusted by rotating in opposite directions, the bayonet lock 9 and the inclined surface 19 can still play a role in positioning an angle, and the user can still conveniently and accurately control the angle adjustment.

One end of the movable rod 8, which is far away from the bayonet 9, is fixedly provided with a rotating handle 16 which is positioned outside the pipe fitting 7, and one side of the pipe fitting 7, which is close to the rotating handle 16, is provided with a retraction groove 17 which is matched with the rotating handle 16.

Specifically, by rotating the handle 16, the user can rotate the handle 16 to adjust the bayonet lock 9 and the inclined plane 19, so that the user can adjust the bayonet lock 9 and the inclined plane 19 more conveniently and more time-saving and labor-saving.

An inclined plane 19 is arranged at one end, far away from the movable rod 8, of each bayonet lock 9, a notch is formed in one side of the surface of each bayonet lock 9, the two bayonet locks 9 are respectively matched with the second special-shaped gear 12 and the first special-shaped gear 6, and the two inclined planes 19 are respectively matched with the second special-shaped gear 12 and the first special-shaped gear 6.

Specifically, the setting of inclined plane 19, the inclined plane 19 height slightly is greater than the height of tooth on the special-shaped gear 6 and the special-shaped gear two 12, consequently rotation special-shaped gear 6 and the special-shaped gear two 12 at the unidirectional can not receive bayonet lock 9's restriction, guarantee that special-shaped gear 6 and special-shaped gear two 12 can rotate in a flexible way, with the setting of the breach of the opposite side of inclined plane 19, make the tooth just block in the breach, thereby play the effect spacing to bayonet lock 9, so just can reduce bayonet lock 9 and cause the damage to the main part of special-shaped gear 6 and special-shaped gear two 12.

One side of the first connecting arm 13 and the second connecting arm 14 is provided with two bolts in a penetrating mode, one side of the first connecting arm 13 is provided with a first welding block 18 through two bolt fixed mounting, one side of the second connecting arm 14 is provided with a first welding block 15 through two bolt fixed mounting, the first welding block 15 is welded on the surface of the first end 1, and the second welding block 18 is welded on the surface of the second end 2.

Specifically, the cooperation of connecting arm one 13, welding piece two 18, connecting arm two 14 and welding piece one 15 is used for whole regulation structures such as basic block 4, pivot round pin 5, pipe fitting 7 can be followed end 1 and end two 2 and pulled down, and this just makes whole regulation structure can adjust and install on the elbow of different internal diameters, in order to satisfy the installation demand of different pipe fittings, brings bigger convenience for user's installation work.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
