Description

Technical Field

[0001] The utility model relates to the technical field of fixing tools for foaming wheels, in particular to a fixing tool for foaming wheels of a handcart. Background Technique

[0002] Handcarts are very common in daily life and production processes. The wheel part of a handcart generally uses a foaming wheel, which is generally composed of a hub part and a rubber part on the outer ring. When processing or maintaining it, it is first necessary to fix it, and a fixing tool for the foaming wheel of a handcart is required in this process. When the existing fixing tool for the foaming wheel of a handcart is in use, it generally fixes the foaming wheel by pressing from the top, so as to facilitate the operator to carry out subsequent maintenance or processing, such as disassembling and replacing the rubber part on its periphery. However, in the actual use process, simply clamping and fixing it from above and below has insufficient stability, and the wheel part is prone to lateral deviation, which in turn affects the operator's maintenance or processing of it.

[0003] In order to solve the above technical problems, a Chinese patent with the publication number CN218875142U in the prior art discloses a fixing tool for a foaming wheel of a handcart, including a workbench. One end of the top of the workbench is provided with a mounting frame, and a mounting bin is installed at the middle position of the bottom of the mounting frame.

A movable plate is sleeved on the outer side of the lead screw near the bottom end.

[0004] Although the above prior art solution is convenient for disassembling and replacing the rubber part on its periphery, it cannot rotate and adjust the angle of the hub after fixing it, which is not conducive to the staff observing the damage and depression at different positions and carrying out repair and maintenance, thus affecting the maintenance efficiency of the staff.
