[0024] To address the limitations of existing wheelchair clamps, which have limited applicability and are inconvenient to disassemble, this invention provides a highly adaptable multifunctional wheelchair clamp and its method of use. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described invention is only a part of this invention, not all of it. All other inventions obtained by those skilled in the art based on this invention without inventive effort are within the scope of protection of this invention.

[0025] Please see Figure 1-5 This invention provides a highly adaptable multi-functional wheelchair clamp, including a base 1. The base 1 is hollow, forming an internal cavity. An adjustment block 20 is provided on the adjustment end of the base 1, which can rotate up and down around the contact position with the base 1. An adjustment bolt 2 is provided on the adjustment end of the adjustment block 20, which can drive the adjustment block 20 to rotate. A left tube clamp 7 and a right tube clamp 9 are provided on the locking end of the base 1, which can rotate relative to or towards each other. The left tube clamp 7 and the right tube clamp 9 are connected by a screw 15, and an adjustment nut 21 is provided through the screw 15 at the position of the left tube clamp 7. A shaped block 13 is provided on the locking end of the right tube clamp 9, and the shaped block 13 is connected to the screw 15 through a cylindrical block 14.

[0026] Furthermore, the adjusting block 20 is connected to the base 1 by the connecting bolt 4. The adjusting end of the adjusting block 20 is hollow and extends through the surface of the adjusting block 20. A positioning pin 5 is provided in the cavity of the adjusting block 20 and is located on the adjusting bolt 2. The adjusting block 20 is fixed in position by the connecting bolt 4 so that it can only rotate along the connecting bolt 4. The hollow shape of the adjusting end of the adjusting block 20 facilitates the rotation of the positioning pin 5 inside and provides space for the adjusting block 20 to rotate. The entire device is rotated by the threaded engagement of the adjusting bolt 2 and the positioning pin 5.

[0027] Furthermore, the base 1 is provided with a mounting bolt 6 at the engaging end, and the left pipe clamp 7 and the right pipe clamp 9 are both provided on the mounting bolt 6. The left pipe clamp 7 is provided with a left positioning pin 8, and the screw 15 passes through the left positioning pin 8 and is connected to the adjusting nut 21. The base 1, the left pipe clamp 7 and the right pipe clamp 9 are connected by the mounting bolt 6. When the adjusting nut 21 is rotated on the screw 15 by the left positioning pin 8, the position of the left pipe clamp 7 can be adjusted.

[0028] Furthermore, the operating end of the right pipe clamp 9 is provided with a wrench fixing seat 11, and a fixing bolt 10 is provided on the wrench fixing seat 11. The irregular block 13 is provided on the fixing bolt 10. The fixing bolt 10 is supported by the wrench fixing seat 11, so that the fixing groove 12 can rotate around the fixing bolt 10.

[0029] Furthermore, a fixing groove 12 is provided on the surface of the irregular block 13, and a handle 17 is provided on the fixing groove 12; the handle 17 is fixed by the fixing groove 12.

[0030] Furthermore, a spring 16 is provided on the surface of the screw 15; with the help of the elastic force of the spring 16, the left tube clamp 7 and the right tube clamp 9 can be separated.

[0031] Furthermore, a fixing rod 3 is provided on the surface of the adjusting block 20, and a connecting rod 19 is provided at the fixed end of the fixing rod 3; the fixing rod 3 is connected to the connecting rod 19.

[0032] Furthermore, the surface of the connecting rod 19 is provided with a connector 18; the connector 18 allows the entire device to be connected to a trailer.

[0033] Furthermore, the gripping ends of both the left and right pipe clamps 7 and 9 are corrugated, which increases the overall friction.

[0034] A method for using a highly adaptable multi-functional wheelchair clamp includes the following steps:

[0035] Step A, clamping: Insert the gap between the left pipe clamp 7 and the right pipe clamp 9 into the pipe rack to be fixed, turn the handle 17 to make the irregular block 13 rotate, so that the irregular block 13, at the position furthest from the fixing bolt 10, fits against the surface of the right pipe clamp 9, turn the adjusting nut 21 to make the left pipe clamp 7 and the right pipe clamp 9 fix the pipe rack, and the fixing is completed.

[0036] Step B, Angle Adjustment: By rotating the adjusting bolt 2, the adjusting block 20 on the surface of the positioning pin 5 moves up and down in the cavity of the base 1 under the action of the thread. Since the adjusting block 20 is connected to the base 1 by the connecting bolt 4, it can only rotate around the connecting bolt 4 as the center. The positioning pin 5 can rotate on the adjusting block 20. In this way, the angle of the adjusting block 20 is adjusted by rotating the positioning pin 5. The rotation stops when the specified angle is reached.

[0037] Step C, Connection: Connect the entire device to the trailer via the connecting rod 19 on the connector 18;

[0038] Step D, detachment: The operator only needs to turn the handle 17 to place the irregular block 13, whose shape is closest to the fixing bolt 10, onto the surface of the right pipe clamp 9, and under the action of the spring 16, the left pipe clamp 7 and the right pipe clamp 9 will detach from the pipe rack.

[0039] Please see Figure 6 This invention provides a highly adaptable multi-functional wheelchair clamp, which is specifically designed to clamp tube frames of different diameters.

[0040] The present invention provides a highly adaptable multi-functional wheelchair clamp and its method of use, which has the following advantages:

[0041] 1. The whole device has a wide range of applications, is easy to operate, and has a small overall locking torque. By adjusting the adjusting nut 21, the left pipe clamp 7 and the right pipe clamp 9 can be tightened on different pipe diameters.

[0042] 2. After installation, no further adjustment is required for the next use. It can be used directly. When it is necessary to detach, no other personnel are needed to assist. One person can simply rotate handle 17 to clamp and detach.

[0043] Although the invention has been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these inventions without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
