It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Example

[0021] In order to solve the technical problems in the prior art, such as Figure 1-2 As shown, the utility model adopts the following technical scheme: a portable tire disassembly and repair tool, comprising a first clamping rod 400 and a second clamping rod 500, the first clamping rod 400 and the second clamping rod 500 are arranged opposite to each other, and the middle parts thereof are hinged at one point, the top of the first clamping rod 400 is hinged to one side of the bearing seat 300, and the other side of the bearing seat 300 is connected to a bearing at one end of a driving screw rod 100, the external thread of the driving screw rod 100 is connected to a displacement nut 200, and the other end of the driving screw rod 100 is provided with a hexagonal screwdriver bit 101, which is connected to an electric wrench, the top of the second clamping rod 500 is hinged to the bottom of the displacement nut 200, and the bottom ends of the first clamping rod 400 and the second clamping rod 500 are both provided with a telescopic rod assembly 600 that can be telescopically adjusted in length and fixed in position, and the bottom end of the telescopic rod assembly 600 is detachably fixedly installed with a tire pressure tensioning assembly 700.

[0022] In one embodiment of the utility model, further, the first clamping rod 400 and the second clamping rod 500 are completely identical in structure, both including a hollow rod body 401, the telescopic rod assembly 600 includes an extension rod 603, one end of the extension rod 603 is fixedly connected to an adjusting screw 601, the adjusting screw 601 is inserted into the rod body 401 from the bottom, the adjusting screw 601 is threadedly connected to the inner thread adjusting sleeve 403, the inner thread adjusting sleeve 403 is connected to the bottom bearing of the rod body 401, a guide cylinder 402 is fixedly connected to one side of the bottom of the rod body 401, one side of the extension rod 603 and close to the adjusting screw 601 is fixedly connected to one end of the guide rod 602, and the guide rod 602 is slidably connected to the guide cylinder 402.

[0023] Specifically, by plugging the sleeve of the electric wrench into the hexagonal screw bit 101 of the driving screw 100, the electric wrench drives the driving screw 100 to rotate, thereby driving the displacement nut 200 to move laterally along the length direction of the driving screw 100, thereby driving the top end of the second clamping rod 500 to move, and because the first clamping rod 400 and the second clamping rod 500 are hinged in the middle, the two tensioning plates 703 arranged opposite to each other at the bottom of the first clamping rod 400 and the second clamping rod 500 are opened and closed, thereby realizing the function of the tool to open or press the tire;

[0024] By driving the two tensioning plates close to each other and squeezing the tire with an electric wrench, the tire can be deformed and fall off the wheel hub, making it convenient and labor-saving to disassemble the tire. Similarly, by inserting two tensioning plates close to each other into the tire at the same time, the two tensioning plates 703 are driven to separate by an electric wrench, thereby stretching the tire to facilitate its repair.

[0025] Secondly, in order to adapt to the use of tires of different models and sizes, a telescopic rod assembly 600 is set up. When the two tensioning plates 703 need a larger opening and closing angle, the inner screw adjustment sleeve 403 is rotated, and with the cooperation of the guide rod 602 and the guide cylinder 402, the adjusting screw 601 can achieve a linear telescopic movement in the rod body 401 to extend or retract, thereby changing the length of the first clamping rod 400 and the second clamping rod 500, so that the tool has a larger opening and closing angle, thereby achieving adaptation and adjustment of the tool according to the thickness of different tires, facilitating operation, and avoiding the disadvantage of carrying a large number of tools. When going out, only the tool is needed to complete the tasks of tire disassembly, opening and the like. It is very practical and can provide strong pressing force and expansion force, completely replacing manual operation, and has strong versatility, is easy to carry, and is easy to store.

[0026] In one embodiment of the utility model, further, the tire pressure tensioning assembly 700 includes a connecting seat 702, the bottom of which is fixedly connected to a plug-in rod 701, the end of an extension rod 603 is provided with a plug-in hole 605, a surface of the extension rod 603 is provided with a connecting hole 604, the connecting hole 604 is connected to the plug-in hole 605, a fastening bolt 800 is provided in the connecting hole 604, the plug-in rod 701 is fastened to the inside of the plug-in hole 605 by a locking bolt, and a tensioning plate 703 is fixedly connected to one side of the connecting seat 702.

[0027] In an embodiment of the present invention, further, the top of the tensioning plate 703 is folded outward to form an anti-slip portion 704, and the two tensioning plates 703 are arranged opposite to each other.

[0028] In an embodiment of the present invention, further, all edges of the tensioning plate 703 are configured as rounded corners.

[0029] In an embodiment of the present invention, further, the inner screw adjusting sleeve 403 is in a circular ring structure, and anti-slip grooves are provided on the surrounding surfaces.

[0030] In an embodiment of the present invention, further, the size of the tensioning plate 703 is divided into three sizes: large, medium and small according to the model of the tire.

[0031] In an embodiment of the present invention, further, the surfaces of the driving screw 100 and the adjusting screw 601 are coated with grease.

[0032] Specifically, by providing the anti-slip portion 704, after the two tensioning plates 703 open the tire, the tire wall can be prevented from slipping out through the everted angle, further improving the stability and safety performance of the tool during use; and by rounding the edges of the tensioning plates 703, damage to the tire during use is prevented, while also effectively protecting the operator's safety.

[0033] At the same time, in order to match the sizes of different tires, three sizes of tensioning plates 703 are matched, namely large, medium and small, and fixedly connected to the top of the extension rod 603 by fastening bolts 800. When in use, it is used according to the actual situation, which further improves the versatility and performance of the tool and makes the operator more comfortable during use.
