DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1, in combination with the attached Figure 1 A multi-position fixing assembly for valve processing includes a support plate 2; a rectangular column 3 is provided at the middle end of the upper side of the support plate 2, and a valve body 1 is located on the outer side of the column 3; a threaded rod 4 is detachably provided at the middle end of the lower side of the support plate 2, and a mounting plate 5 is connected to the lower end of the threaded rod 4, and a plurality of mounting holes 6 are provided on the circumference of the mounting plate 5.

[0024] Combined with Figure 1-4 , an internal fixing assembly is provided in the column 3, and the internal fixing assembly includes a mounting groove 7 provided on the column 3, a motor 8 is provided at the lower end of the mounting groove 7, a driving rod 9 is provided at the output end of the motor 8, and a gear 10 is connected to the upper end of the driving rod 9; a slide bar 11 is slidably provided at the upper end of the column 3 and near the front and rear ends, and the opposite sides of the slide bar 11 are provided with tooth patterns that can mesh with the gear 10; the motor 8 drives the gear 10 to rotate through the driving rod 9, thereby driving the meshing slide bar 11 to move in the opposite direction until the end of the slide bar 11 is pressed against the valve body 1;

[0025] Combined with Figure 2 , 3 A limit slider 12 is provided under the slide bar 11, and a limit slot 13 which can be slidably connected with the limit slider 12 is provided at the upper end of the column 3 and located on the front and rear sides of the mounting groove 7; the cross-sections of the limit slider 12 and the limit slot 13 are both inverted T-shaped; the limit slider 12 and the limit slot 13 can limit the slide bar 11 so that it can only move and will not fall out upward.

[0026] Combined with Figure 1-4 The slide bars 11 are all L-shaped, and an arc plate 19 is provided at one end away from each other. A rubber pad is provided on the outside of the arc plate 19 and contacts the inner side of the valve body 1; the arc plate 19 can increase the contact area between the slide bar 11 and the inner side of the valve body 1, making the abutment tighter.

[0027] Combined with Figure 1 , 5 An external fixing component is provided on the outside of the valve body 1, and the external fixing component includes a nut 14 threadedly connected to the outside of the threaded rod 4, and a swivel 15 is rotatably provided on the outside of the nut 14. The front and rear sides and the left and right sides of the swivel 15 are hinged with support arms 16, and the upper end of the support arm 16 extends out of the support plate 2 and is hinged with an extrusion plate 18; when in use, the nut 14 is rotated to make the nut 14 move up and down on the outside of the threaded rod 4, thereby driving the swivel 15 to move, so that the upper end of the L-shaped support arm 16 will move toward or away from each other under the drive of the swivel 15 and under the restriction of the rectangular through hole 17, completing the fixing and loosening of the outside.

[0028] In the above process, since the swivel 15 and the nut 14 are rotationally connected, the swivel 15 will only move up and down under the drive of the nut 14 and the restriction of the support arm 16, and will not rotate; at the same time, the rectangular through hole 17 serves to limit the support arm 16 and leaves a margin for it to move.

[0029] Combined with Figure 1 The extrusion plates 18 are all arc-shaped and are in contact with the outer side of the valve body 1; the opposite sides of the extrusion plates 18 are provided with anti-slip pads, which can increase the friction force in contact with the valve body 1.

[0030] The working principle of the utility model is as follows: when in use, the whole can be connected to an external driving device through the mounting plate 5, so as to drive the valve body 1 to rotate; when the valve body 1 needs to be fixed from the outside, the nut 14 is rotated downward on the outside of the threaded rod 4, driving the swivel 15 to move downward, thereby driving the L-shaped support arms 16 to clamp toward each other, and limiting the valve body 1; when the valve body 1 needs to be fixed from the inside, the motor 8 drives the gear 10 to rotate through the driving rod 9, thereby driving the two slide bars 11 to move in opposite directions until the arc plate 19 presses the valve body 1 tightly.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
