Disclosure of Invention

The invention aims to overcome the defects and provide the tire spreader which is labor-saving, high in speed and convenient to use.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention relates to a tire spreader, which is characterized in that; fixed mounting has connecting seat B (7) above the straight-bar, middle part below, both ends fixed mounting has supporting seat A respectively, supporting seat B, dop A, the roof is twisted to the right-hand member head, connecting seat B card goes into connecting seat A and inserts axle A and connect, connecting seat A is fixed connection chap respectively, the arm of force, fixed mounting has dop B above the chap, be provided with the spout on the arm of force, the spout outside that the sliding sleeve set up on the arm of force, the screw shaft passes the sliding sleeve, the gasket is being twisted the screw sleeve on the spout upper end is sheathe in, lower extreme fixed connection connecting seat C, connecting seat C card goes into connecting seat D and inserts.

The arm is rotatable about an axis A.

The top plate is rotatably adjustable.

The lower end of the gasket is clamped in the sliding sleeve.

The clamping heads A and B are arc-shaped grooves.

The threaded sleeve is fixedly connected with the handle.

Compared with the prior art, the invention is characterized in that the connecting seat B is fixedly arranged on the straight rod, the supporting seat A, the supporting seat B and the clamping head A are respectively and fixedly arranged at the middle part and two ends of the lower part of the straight rod, the right end head is screwed into the top plate, the connecting seat B is clamped into the connecting seat A and is inserted into the shaft A for connection, the connecting seat A is respectively and fixedly connected with the supporting head and the force arm, the clamping head B is fixedly arranged on the supporting head, the force arm is provided with a sliding groove, the sliding sleeve is sleeved outside the sliding groove arranged on the force arm, the screw shaft penetrates through the sliding sleeve and a gasket sleeved on the upper end of the sliding groove and is screwed into the screw sleeve, the lower end of. The clamping heads A and the clamping heads B are inserted into the upper end and the lower end of the inner opening of the tire, the top plate props against the upper end and the lower end of the inner opening of the tire, the force arm is rotated by rotating the handle with the shaft A as the center, and the clamping heads B rotate with the shaft A (2) as the center along with the supporting head to support the inner opening of the tire, so that labor is saved, the speed is high, and the use is convenient.
