[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 The utility model provides an embodiment: a tightly connected torsion bar tempered and polished rod for a steering machine, comprising a tempered and polished rod body 1, two buckles 2 are sleeved on both ends of the outer wall of the tempered and polished rod body 1, two engaging members 3 fixedly connected to both sides of the top buckle 2 are arranged inside the engaging grooves 4 opened on both sides of the bottom buckle 2, one side of the buckle 2 is fixedly connected with an anti-skid pad 8, and the adjacent sides of the anti-skid pads 8 at both ends are provided with tooth grooves, and the other side of the buckle 2 is provided with a slide groove 9, and a slide member 10 is slidably connected inside the slide groove 9, and a limiting component is provided on one side of the slide member 10, and the other side of the slide member 10 passes through one side of the inner wall of the slide groove 9, and is connected to the outer wall of the tempered and polished rod body 1 through an anti-skid pad 13, one side of the anti-skid pad 13 is fixedly connected to one side of the slide member 10, and the other side of the anti-skid pad 13 is tightly pressed against the outer wall of the tempered and polished rod body 1;

[0024] Specifically, the anti-skid pad 8 with tooth grooves for increasing friction is used to abut on both sides of the gears that need to be transmitted by the steering gear, so that the buckle 2 installed on the tempered and polished rod body 1 can bite the gear, so that the gear can increase the tightness of the connection with the tempered and polished rod body 1 through the buckle 2, thereby increasing the transmission performance of the tempered and polished rod body 1, reducing energy consumption, and maximizing the transmission efficiency of the steering gear. The buckle 2 is an external component that can be freely disassembled, so as to facilitate the maintenance of various components, extend the service life of the structure, and ensure that the tempered and polished rod body 1 can continue to be in the most efficient transmission state. After one of the buckles 2 is put on the outer wall of the tempered and polished rod body 1, the other buckle 2 is placed obliquely above one of the buckles 2 and put on the tempered and polished rod body 1, and then the other buckle 2 is gradually straightened until the engaging piece 3 connected to one of the buckles 2 is embedded in the engaging groove 4 opened on the other buckle 2, so that it is positioned and completely installed, and the two buckles 2 are slid until the buckle 2 with the anti-slip gasket 8 is against the gear set on the tempered and polished rod body 1.

[0025] Two half screws 5 are fixedly connected to the two ends of the buckle 2, the outer walls of the top half screw 5 and the bottom half screw 5 are threadedly connected with a fixing screw sleeve 6, and the outer wall of the fixing screw sleeve 6 is fixedly connected with two force applying members 7;

After one of the buckles 2 is put on the outer wall of the tempered and polished rod body 1, the other buckle 2 is placed obliquely above one of the buckles 2 and put on the tempered and polished rod body 1. Then the other buckle 2 is gradually straightened until the fitting piece 3 connected to one of the buckles 2 is embedded in the fitting groove 4 opened on the other buckle 2, so that it is positioned and installed completely, and the two buckles 2 are slid until the buckle 2 with the anti-slip gasket 8 is against the gear set on the tempered and polished rod body 1, and the two buckles 2 are The half screws 5 on the top will be spliced ​​together. At this time, the fixing screw sleeve 6 can be put on the two half screws 5 and tightened to firmly fix the buckle 2 of the connected half screws 5, thereby fixing the two buckle rings 2, and then insert the limit piece 11 into the side opening of the slide groove 9 on the other side of the buckle ring 2, so that the limit piece 11 is squeezed into the slide groove 9, and one end of the slide piece 10 connected with the anti-skid pad 13 is squeezed out of the opening of the slide groove 9 on one side of the tempered and polished rod body 1, the limit piece 11 is tightly fixed in the slide groove 9, and the slide piece 10 is squeezed, so that the rubber anti-skid pad 13 is pressed against the tempered and polished rod body 1, and the buckle 2 is fixed on the tempered and polished rod body 1 to complete the installation.
