[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figure 1-5 A multifunctional tire expander includes two end support plates 1, which are connected by a guide rod 2. A driving component is installed on the two end support plates 1, and a balancing component is installed on the outer wall of one of the two end support plates 1.

[0022] The driving component includes two rotating rods 3, which are movably inserted into two end support plates 1 respectively, and are connected to each other by a connecting seat 4. A hexagonal nut 5 is installed at one end of each rotating rod 3. Threads are opened on both rotating rods 3, and the threads on the two rotating rods 3 are in opposite directions. A clamping frame is movably fitted on each rotating rod 3 by the threads. The driving component also includes a handle.

[0023] Specifically, the clamping frame includes a movable nut 6, which is threadedly fitted onto the rotating rod 3. A vertical plate 7 is fixedly fitted onto the movable nut 6. A guide rod 2 passes through the vertical plate 7. A clamping plate 8 extends downward at the lower end of the vertical plate 7. A horizontal pressure plate 9 is installed on the clamping plate 8 and on the wall corresponding to the end support plate 1.

[0024] It should be noted that in the initial state of the device, the clamping brackets on the two rotating rods 3 are close to the connecting seat 4, the drive component passes through the axis of the tire, the two clamping brackets are inserted into the opening of the tire, the angle formed by the pressure plate and the clamping plate 8 in the clamping brackets is clamped at the edge of the tire opening, and the handle is installed on the hexagonal nut 5.

[0025] Specifically, the handle includes a sleeve 10, one end of which has a hexagonal locking hole that matches a hexagonal nut 5, and the other end of the sleeve 10 is fitted with a handle 11.

[0026] It should be noted that the sleeve 10 is fitted onto the hexagonal nut 5 through the hexagonal locking hole. The operator can rotate the handle 11, which drives the sleeve 10 to rotate. The hexagonal nut 5 then drives the two rotating rods 3 and the connecting seat 4 to rotate. Under the guidance and limitation of the guide rod 2, the clamping frame moves along the axial direction of the rotating rod 3 through the threaded engagement of the movable nut 6 and the rotating rod 3. The two clamping frames move away from each other at the same time, expanding the tire bead and improving the efficiency of tire expansion. The operator can also use an electric wrench to replace the handle. The electric wrench only needs to use a socket that matches the hexagonal nut 5. It can be matched with various power sources to make the driving components work, saving the operator's physical strength.

[0027] Specifically, the balancing component includes a hollow square steel 12, which is installed on the outer wall of the end support plate 1. Two moving bars 13 that match the hollow square steel 12 are movably inserted into the hollow square steel 12. Each moving bar 13 has a groove on its upper wall. Bolts 14 are movably inserted into both ends of the upper wall of the hollow square steel 12 through threads. A clamping element is installed at one end of each bolt 14. Multiple spring columns 15 are installed on the wall corresponding to each moving bar 13 and the clamping frame. A stop plate 16 is installed at one end of each spring column 15.

[0028] It should be noted that before installing the device on the tire, the moving bar 13 is pulled laterally to adjust the two abutments 16 to be aligned with the tire. That is, when the two clamping frames are inserted into the tire opening, the abutments 16 on both sides can fit against the tire. Then, the bolts 14 are tightened until the clamping parts are pressed into the grooves on the moving bar 13 to fix the moving bar 13. When installing the device on the tire, the end without the balancing parts is inserted through the tire. The angle formed by the pressure plate in the clamping frame and the clamping plate 8 is clamped at the edge of the tire opening. At this time, the spring column 15 is slightly compressed. Through the rebound force generated by the spring column 15 and the limiting of the clamping frame, the device is stably installed on the tire, which makes it easy to install the handle or electric wrench on the hexagonal nut 5. The adjustable moving bar 13 and the telescopic spring column 15 make the device suitable for tires of different sizes.

[0029] Specifically, the clamping component includes an extension post 17, which is installed on one end of the bolt 14. A pressure block 18 is movably mounted on the extension post 17 and is movably fitted against the bottom surface of the inner side of the groove.

[0030] It should be noted that the pressure block 18 can be made of rubber. After the pressure block 18 is attached to the groove, the bolt 14 is continuously rotated. The bolt 14 drives the extension column 17 to rotate in the pressure block 18, so that the pressure block 18 is tightly pressed into the groove, thus fixing the moving strip 13.

[0031] Preferably, and further, a first bearing 19 is provided between the end support plate 1 and the rotating rod 3 for movable connection between the end support plate 1 and the rotating rod 3;

[0032] Preferably, a second bearing 20 is provided between the extension column 17 and the pressure block 18 for movable connection between the extension column 17 and the pressure block 18.

[0033] Although embodiments of the present invention have 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 embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
