[0015] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4 It is given, including a fixed column 1, a plurality of limit slots 2 evenly distributed along the upper and lower directions are opened on the right side of the fixed column 1, and the limit slots 2 are triangular. A plurality of fixing frames 3 distributed along the upper and lower directions are sleeved on the fixed column 1, a clearance slot 4 is opened in the fixing frame 3, and a limiting block 5 is slidably connected in the clearance slot 4. The left end of the limiting block 5 can be inserted into the limiting slot 2 on its corresponding side, and a plurality of upper spring pieces 6 evenly distributed along the circumferential direction are fixedly connected to the upper side of the outer wall of the fixing frame 3, and a plurality of lower spring pieces 7 corresponding to the upper spring pieces 6 are fixedly connected to the lower side of the outer wall of the fixing frame 3. A movable top rod 8 is provided between the upper spring piece 6 and the lower spring piece 7. The top rod 8 can drive the upper spring piece 6 and the lower spring piece 7 on the corresponding side to move relative or back to each other, and the lower end of the lower spring piece 7 is fixedly connected to a pick 9.

[0017] like Figures 1 to 4 As shown, the setting of the fixing column 1, the limiting groove 2, the fixing frame 3 and the limiting block 5 can utilize the function of the limiting block 5 and the limiting groove 2 to fix the fixing frame 3 on the fixing column 1, and the distance between multiple fixing frames 3 can be adjusted according to needs, which is convenient for coating the adapter. The upper spring piece 6, the lower spring piece 7, the push rod 8 and the paddle 9 are convenient for clamping the adapter with the upper spring piece 6 and the lower spring piece 7. At the same time, the movement of the push rod 8 can be used to quickly release the clamping of the upper spring piece 6 and the lower spring piece 7 on the adapter, which is convenient for quickly removing the adapter. The paddle 9 can paddle the lower spring piece 7 downward, thereby quickly opening the gap between the upper spring piece 6 and the lower spring piece 7, thereby facilitating the placement and connection of the adapter. At the same time, the adapter can be fixed by loosening the paddle 9, which is convenient and quick, and there is no need for workers to use both hands to separate the upper spring piece 6 from the lower spring piece 7.

[0018] The right side of the fixing frame 3 is rotatably connected with a screw 10 , the left side of the screw 10 is threadedly connected to the limit block 5 on its corresponding side, and the right end of the screw 10 is fixedly connected with a knob.

[0019] like Figures 1 to 3 As shown, a screw 10 and a knob are provided, so that the screw 10 can be driven to rotate by the knob, and then the limit block 5 is driven to move left and right in the displacement groove 4 through the action of the threaded connection. When the limit block 5 is inserted into the limit groove 2, the fixing frame 3 can be fixed. When the limit block 5 is disengaged from the limit groove 2, the position of the fixing frame 3 on the fixing column 1 can be changed, and it can even be removed from the fixing column 1 when necessary, which facilitates the division of labor in fixing the adapter and improves efficiency.

[0020] The opposite ends of the upper spring piece 6 and the lower spring piece 7 are respectively provided with a slide groove 11, and the upper and lower sides of the push rod 8 are respectively located in the slide groove 11 on their corresponding sides. The outer wall of the fixed frame 3 is provided with a plurality of movable grooves 12 corresponding to the push rod 8 one by one. A screw rod 13 is fixedly connected to the middle part of the push rod 8, and the screw rod 13 is located in the movable groove 12 on its corresponding side. A rotatable spur gear 14 is threadedly connected to the outer wall of the screw rod 13. The spur gear 14 is rotatably connected to the fixed frame 3, and a face gear 15 is rotatably connected inside the fixed frame 3, and the spur gear 14 is engaged with the face gear 15.

[0021] like Figure 4 As shown, the sliding groove 11 is provided to facilitate limiting the push rod 8, so as to prevent the push rod 8 from being skewed and unable to open the upper spring piece 6 and the lower spring piece 7. The movable groove 12, the screw rod 13, the spur gear 14 and the face gear 15 are provided. The rotation of the face gear 15 can drive all the spur gears 14 to rotate, and then the screw rod 13 is driven by the spur gear 14 to approach or move away from the axis of the fixed column 1, and then the push rod 8 can be driven to open the upper spring piece 6 and the lower spring piece 7, so as to achieve the purpose of quickly and uniformly removing the adapter from the fixing frame 3.

[0022] An arcuate slot 16 is formed on the upper end of the fixing frame 3 , and a handle 17 is fixedly connected to the upper end of the face gear 15 . The handle 17 is located in the arcuate slot 16 on the corresponding side.

[0023] like Figures 1 to 3 As shown, the arc groove 16 and the handle 17 are provided to facilitate the use of the handle 17 to rotate the face gear 15, so that the face gear 15 drives the spur gear 14 to rotate synchronously, thereby facilitating the operation of workers and quickly removing the adapter.

[0024] One end of the lower spring piece 7 is provided with a triangular groove 18 , one end of the upper spring piece 6 is triangular and located in the groove 18 on the corresponding side, and the upper end of the fixing column 1 is rotatably connected to a hook.

[0025] like Figures 1 to 2 As shown, the groove 18 and one end of the upper spring piece 6 are arranged to be triangular, which can facilitate the clamping of the rotating head. At the same time, the groove 18 can be used to clamp the adapter, so that the adapter can be swung freely after being fixed, causing it to fall or tilt. The hook is provided to facilitate hanging the whole in a suitable position for coating.

[0026] When the utility model is in use, a worker can use the paddle 9 to push the lower spring piece 7 downward, and then the distance between the lower spring piece 7 and the upper spring piece 6 becomes larger, and the adapter can be put on the upper spring piece 6. At the same time, the paddle 9 is released to make the lower spring piece 7 rebound, and the adapter can be fixed between the upper spring piece 6 and the lower spring piece 7. Similarly, the upper adapter can be fixed between all the upper spring pieces 6 and the lower spring pieces 7 at the upper end of the fixing frame.

[0027] After the fixation is completed, the screw 10 is driven by the knob to rotate so that the limit block 5 is completely inserted into the clearance groove 4. Then, the fixing frame 3 is sleeved on the fixing column 1 at a suitable position, and then the knob is turned. The knob drives the limit block 5 to enter the limit groove 2 on the corresponding side through the screw 10. Then, the required fixing frames 3 are fixed on the fixing column 1. Then, the hook can be used to hang the whole in the appropriate position. The fixed adapter can be coated until the coating work is completed and the whole can be removed from the hanging place;

[0028] Then use the handle 17 to rotate the face gear 15, the face gear 15 drives all the spur gears 14 to rotate, and then the spur gear 14 drives the screw 13 to move toward the central axis of the fixed column 1, and the screw 13 drives the push rod 8 to move. While the push rod 8 moves in the slide groove 11, it drives the upper spring piece 6 and the lower spring piece 7 to move oppositely, so that the fixation of the adapter can be released, and then the adapter can be quickly removed. The screw 13 has a self-locking ability, which can prevent the upper spring piece 6 and the lower spring piece 7 from rebounding quickly. After the adapter is removed, the handle 17 can be turned to move the two spring pieces relative to each other again, and then the uncoated adapter can be fixed again.

Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
