As a practical further explanation: and a buffer rubber pad is arranged on one side of the pressing plate, which is far away from the pressing rod.

As a practical further explanation: the bottom plate is provided with two control buttons which are respectively connected with a rotating motor.

As a practical further explanation: the protection plate is installed on one side of the bottom plate and perpendicular to the bottom plate, and the part, with the height exceeding the lantern ring, of the protection plate is bent towards the lantern ring direction.

As a practical further explanation: an observation window is installed at the bent portion of the shield plate.

Compared with the prior art, this practicality has following profitable technological effect:

1. the staff will need welded mechanical tubes to place respectively in the cover intra-annular, be fixed in the cover intra-annular respectively with the pipe fitting through compressing tightly the pole, weld it again, and it rotates through control button control simultaneously, and the convenience need not the manual work and assists always to the centre gripping and the location of pipe fitting, only needs the initial manpower to adjust to welded convenience and precision have been promoted.

2. The staff is welding, and the staff can follow the observation window and observe when the guard plate can be protected to it, does not influence welding operation.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a detailed description of the present invention will be given below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that the present application product is conventionally placed in use, and are merely used for convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
