[0021] The utility model analyzes the reason that the existing Christmas tree is easy to be poked in the process of moving and installing to the production line. It is found that since the Christmas tree trunk and the Christmas tree fixing device are both two narrow sleeves, in the process of moving and installing, the Christmas tree must be installed on the Christmas tree fixing device by observing whether the trunk and the sleeve are aligned with the eyes. However, the Christmas tree has loose and swollen branches and leaves which block the line of sight of the workers, especially large Christmas trees. Therefore, the workers need to bend down and look around to find the field of view. In this process of looking around, it is easy to be poked by the branches and leaves by accident, and the branches and leaves can even poke the eyes seriously. In addition, sometimes the workers may move the branches and leaves during the process of looking around, and the branches are also very easy to poke the eyes when rebounding. The utility model analyzes and thinks that in order to prevent the situation of poking the eyes from happening, the workers' behavior of looking around during the installation process should be reduced. This means that the need for eye observation during the installation process of the Christmas tree should be reduced, and the trunk and the clamp can be easily aligned and installed.

[0022] Therefore, the utility model increases the notch and the positioning plate on the sleeve as the positioning guide, so that the workers can find the installation height along the positioning plate without looking around by touching the positioning plate with the bottom end of the trunk, and the Christmas tree trunk can be smoothly inserted into the sleeve with the help of the notch. At the same time, the seat pipe clamp with a longer handle is used as the locking mechanism, so that the locking and relaxing can be realized without looking around.

[0023] The utility model will be described in detail below in combination with the drawings. Figures 1-5 The scheme of the utility model will be described in detail.

[0024] A Christmas tree fixing clamp comprises a sleeve, a seat pipe clamp, and a sleeve inner column 30. The sleeve is used to be inserted into the trunk of a Christmas tree. The seat pipe clamp is clamped on the sleeve. The seat pipe clamp has a locking state and a loosening state. When the seat pipe clamp is in the locking state, the sleeve is slightly deformed to clamp the trunk of the Christmas tree inwardly. When the seat pipe clamp is in the loosening state, the worker can disassemble or assemble the Christmas tree into or from the sleeve. The sleeve inner column 30 is fixed inside the sleeve. The trunk of the Christmas tree is installed between the sleeve and the sleeve inner column 30. The sleeve inner column 30 clamps the trunk of the Christmas tree together with the sleeve. Preferably, the sleeve inner column 30 is a cylindrical column, and the axis of the sleeve inner column 30 coincides with the axis of the sleeve.

[0025] The sleeve comprises a sleeve body 11, a height limiting platform 14, and a bottom limiting plate. One side of the side wall of the sleeve body is provided with a notch 12 extending downward from the top end. The width of the notch 12 is greater than the outer diameter of the trunk of the Christmas tree. The other side of the side wall of the sleeve body 11 is provided with a longitudinal slit 13, as shown in Figure 1 and Figure 2 The height limiting platform 14 is fixed on the outer wall of the sleeve body 11 and is higher than the lowest end of the longitudinal slit. The upper surface of the height limiting platform 14 is flush with the lowest end of the notch 12. The height limiting platform 14 is used to assist the alignment of the bottom end of the trunk of the Christmas tree with the bottom end of the notch 12. Preferably, the height limiting platform 14 is located on the side of the sleeve body 11 where the notch 12 is located, as shown in Figure 3 In this embodiment, the height limiting platform 14 is a metal plate welded on the side of the sleeve body 11 where the notch 12 is located, as shown in Figures 1-3 Preferably, the two side edges of the height limiting platform 14 are further provided with flanges (not shown in the figure) for limiting and guiding the trunk of the Christmas tree, so as to avoid the sliding of the Christmas tree from the two sides of the height limiting platform 14. The bottom limiting plate is horizontally welded and fixed on the inner wall of the lower part of the sleeve body 11.

[0026] The seat pipe clamp comprises a clamp ring 21, a screw rod 22, a first nut 24, a handle 23, a hole pin 231, a second nut 25, and a rubber sheet 26, as shown in Figure 4The two ends of the clamping ring 21 are provided with two fixed ears 211, and the two fixed ears 211 are each provided with an opening, and the centers of the openings are opposite and have the same diameter. The clamping ring 21 is sleeved on the outer periphery of the sleeve body 11 and is located between the lowest end of the longitudinal slit and the height limiting platform. The screw rod 22 passes through the openings of the two fixed ears 211, and one end is fixedly screwed with the first nut 24. The handle 23 includes a joint part and a hand holding part, and the joint part is provided with a positioning hole. The handle 23 is fixedly connected with the end of the screw rod 22 away from the first nut 24 through a hole pin 231: the pin body of the hole pin 231 passes through the positioning hole of the handle 23 and exposes a pin hole; the pin head is clamped above the positioning hole so that the hole pin 231 cannot continue to pass out; the other end of the screw rod 22 passes through the pin hole of the hole pin 231, and the exposed part is fixedly screwed with the second nut 25. The handle 23 can rotate around the positioning hole and the hole pin 231. The film 26 is attached between the joint part of the handle 23 and the fixed ear 211 adjacent to the joint part, so as to reduce the abrasion between the joint part and the fixed ear 211. When the handle 23 is rotated and the hand holding part of the handle 23 is away from the sleeve, as shown in Figure 3 、 4 the distance between the contact point of the joint part of the handle 23 and the film 26 and the positioning hole is small, the extrusion force of the joint part of the handle 23 on the clamping ring 21 is small, and the seat pipe clamp is in a relaxed state; when the handle hand holding part is close to the sleeve, as shown in Figure 5 the distance between the contact point of the handle joint part and the film and the positioning hole is large, and then the extrusion force of the joint part of the handle 23 on the clamping ring 21 is large, and the seat pipe clamp is in a locked state, thereby extruding the sleeve body 11 to make it tight.

[0027] Preferably, in order to prevent the seat pipe clamp from sliding down in the relaxed state, the embodiment further provides a seat pipe clamp limiting part (not shown in the figure) outside the sleeve, which is located between the seat pipe clamp and the lowest end of the longitudinal slit to prevent sliding down. In one embodiment, the seat pipe clamp limiting part is specifically a rubber ring which is tightly sleeved on the outer wall of the sleeve body 11. In another embodiment, the seat pipe clamp limiting part is a plurality of protruding parts on the outer wall of the sleeve body 11, specifically a plurality of convex points.

[0028] The sleeve inner column 30 is welded and fixed to the bottom limiting plate inside the sleeve body 11 and is a cylinder. The axis of the sleeve inner column 30 coincides with the axis of the sleeve body 11, the outer diameter of the sleeve inner column 30 is smaller than the inner diameter of the sleeve body 11, and the outer diameter of the sleeve inner column 30 is slightly smaller than the inner diameter of the Christmas tree trunk.

[0029] Further, the present application finds that the height limiting platform 14 will block the worker from reaching the handle of the seat pipe clamp, and therefore the position of the seat pipe clamp is improved: the two fixed ears 211 of the seat pipe clamp are located on the side of the sleeve body 11 with the slit 13, and therefore the height limiting platform 14 located on the side of the notch 12 will not block the fixed ear 211 of the seat pipe clamp and the handle 23 connected therewith, so that the worker can contact the handle 23 from above without being blocked by the height limiting platform 14.

[0030] Further, the utility model discloses that the fixture has obvious noise in the use process, therefore makes improvement: the inner wall of sleeve inner column 30 outer wall and sleeve main part 11 are all pasted with fluff material, increase the friction between sleeve inner column 30, sleeve main part 11 and christmas tree trunk, prevent the relative rotation of christmas tree relative to christmas tree fixture, also can reduce the noise in the installation and movement process.

[0031] When the worker installs the christmas tree on the christmas tree fixture on the production line, the seat pipe clamp handle 23 is unfolded, and the seat pipe clamp is in a relaxed state. The worker holds the trunk of the upper part of the christmas tree and probes in the direction of the fixture. When the trunk touches the height limiting platform 14, the worker can lift the christmas tree along the height limiting platform 14, so that the bottom end of the trunk is placed on the height limiting platform 14. Then, the worker can probe in the direction of the sleeve. When the bottom of the trunk reaches the gap 12, the trunk can be smoothly placed into the sleeve without being lifted again. If the direction of the probe deviates, the worker only needs to make the bottom end of the trunk slide along the flange of the height limiting platform 14, so that the trunk can be guided to the gap 12 and finally smoothly placed into the sleeve. After the christmas tree is inserted into the sleeve, the christmas tree falls to the bottom limiting plate. At this time, the sleeve inner column 30 is located in the trunk, and the outer wall of the trunk is surrounded by the sleeve main part 11. The worker closes the seat pipe clamp handle 23 and locks the seat pipe clamp. Then, the sleeve is deformed and tightened, and the sleeve inner column 30 cooperates to clamp the trunk of the christmas tree.

[0032] Compared with the prior art, the utility model has the following advantages:

[0033] 1. The utility model can enable the worker to accurately find the position and smoothly install the christmas tree without repeatedly probing and observing the eye during the process of installing the christmas tree on the fixture. The problem that the worker is easily poked in the eye when installing the christmas tree is solved.

[0034] 2. The seat pipe clamp handle 23 is long and large, so the worker can also not need to repeatedly probe and observe, but only needs to stretch the hand to touch the handle 23 and lock the seat pipe clamp. The operation is convenient, fast and safe.

[0035] 3. The axis of the trunk of the christmas tree coincides with the axis of the sleeve inner column 30 and the sleeve main part 11 when the fixture is clamped. Therefore, when the fixture is fixed on the production line and moves with the conveying device and rotates in front of the fluff spraying machine, the fixture can be more accurately aligned and kept in a uniform rotation axis, so that the fluff spraying effect is more uniform.
