[0019] The following description, in conjunction with the accompanying drawings, further illustrates the adjustable and replaceable multifunctional bracket of this utility model.

[0020] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] See Figures 1-3 As shown, an adjustable and replaceable multifunctional bracket includes a base plate 1 and a detachable connecting positioning tube 2 mounted on the base plate 1; characterized in that it also includes a detachable top rod assembly mounted on the connecting positioning tube 2 and with adjustable height, a screw sleeve 3 movably mounted on the top rod assembly, a screw 4 connected to the screw sleeve 3 and located within the top rod assembly, and a top head 5 mounted on one end of the screw 4. The top rod assembly includes a top rod C6 connected to the connecting positioning tube 2 and a top rod A7 detachably mounted on the top rod C6.

[0023] The connecting positioning tube 2 can be installed on the base plate 1 by thread, but is not limited to threaded connection. The push rod A7 and the push rod C6 can also be connected by thread, but are not limited to threaded connection. The push rod C6 and the connecting positioning tube 2 can also be connected by thread, but are not limited to threaded connection.

[0024] The top head 5 can be installed on the screw 4 by means of screws or pins;

[0025] With the adjustable height of the top rod assembly, the height of the top rod assembly can be adjusted according to the location and working environment, so that one bracket can meet different needs and has wide applicability.

[0026] In one embodiment, it further includes at least one detachable adjusting rod 8 installed between the push rod A7 and the push rod C6;

[0027] The adjusting rod 8 can also be connected to the adjusting rod A7 and the adjusting rod by thread, but it is not limited to threaded connection. It can also be connected by means of pins, etc.

[0028] When in use, the height of the push rod assembly can be adjusted by installing an adjusting push rod 8 between push rod A7 and push rod C6, depending on the usage requirements.

[0029] In one embodiment, a bearing 71 is also included, which is mounted on the push rod A7 and located between the push rod A7 and the screw sleeve 3 to reduce the resistance when the screw sleeve 3 rotates. The upper end of the push rod A7 is provided with a recess 72 for positioning and mounting the bearing 71.

[0030] The recessed platform 72 limits the installation position of the bearing 71. The bearing 71 reduces the resistance when the screw sleeve 3 rotates, making it easier to rotate the screw sleeve 3 to drive the screw 4 to perform lifting and lowering actions.

[0031] In one embodiment, the device further includes a handle 31 mounted on the screw sleeve 3 to facilitate the rotation of the screw sleeve 3 and drive the screw 4 to perform lifting and lowering actions, and a handle sleeve 32 mounted on the handle 31; the handle 31 facilitates the operator to rotate the screw sleeve 3.

[0032] In one embodiment, a limiting part is also provided on the screw 4 to limit the extension stroke of the screw 4 and prevent overtravel. The limiting part breaks the thread structure on the screw 4, so that the screw 4 and the screw sleeve 3 cannot continue to rise through the threaded engagement, thereby limiting the rising distance of the screw 4 and preventing the screw 4 from falling off the support due to overtravel during the lifting of the load.

[0033] The limiting part can also be formed by fixing a limiting ring on the screw 4 by welding or screws. By fixing the limiting ring on the screw 4, the rising distance of the screw 4 can be limited.

[0034] In one embodiment, a handle 73 is provided on the top rod A7 for easy lifting, so that the operator can easily lift the entire bracket.

[0035] In one embodiment, the system further includes a top head fixing member 11 disposed on the base plate 1 for storing the top head 5 and preventing the top head 5 from being lost, and a top rod fixing member 12 disposed on the base plate 1 for storing the adjusting top rod 8 and preventing the adjusting top rod 8 from being lost.

[0036] The top head fixing part 11 and the top rod fixing part 12 can be fixedly installed on the base plate 1 by welding or other fixing methods. When not in use, the top head 5 can be installed on the top head fixing part 11, and the adjusting top rod 8 can also be installed on the top rod fixing part 12 when not in use, so as to avoid the loss of the unused top head 5 and adjusting top rod 8. The top head 5 can be installed on the top rod fixing part 12 by screws or pins, and the adjusting top rod 8 can be installed on the top rod fixing part 12 by threads, screws, pins or other methods.

[0037] It also includes a flexible protective pad 9 installed on the top head 5 to buffer and protect the load and the top head 5;

[0038] By installing a detachable top head 5 on the upper end of the screw 4, different top heads 5 can be selected and installed according to working conditions during use. At the same time, by installing a flexible protective pad 9 on the top head 5, a buffering effect is provided between the top head 5 and the load, avoiding hard contact between the top head 5 and the load and causing damage to the load.

[0039] The mandrel 5 can be any of the following shapes: round mandrel 5, V-shaped mandrel 5, or other mandrel 5 shapes.

[0040] When using this utility model: First, select whether to install the adjusting rod 8 and the number of adjusting rods 8 according to the working conditions. If necessary, install the adjusting rod 8 between the rod C6 and the rod A7. If not necessary, install the rod A7 directly on the rod C6.

[0041] When lifting or lowering the load, the operator turns the handle 31, which drives the screw sleeve 3 to rotate. The screw sleeve 3, through its threaded engagement with the screw rod 4, drives the screw rod 4 to move up or down.

[0042] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
