The above-mentioned scheme can be used in the scenario of adjusting the clamping block in the clamping of the steering gear shell, and can also be used to solve the problem of movement of the horizontal clamp.

[0021] In this embodiment, by adjusting the distance between the transverse clamp 102 and the vertical clamp 103, the transverse clamp 102 and the vertical clamp 103 can clamp steering gear housings of different sizes, thereby improving the clamping stability and clamping effect of the steering gear housing.

The movable sleeve 105 is embedded in and welded inside the vertical clamping block 103. The movable sleeve 105 is provided with a thread. During adjustment, the rotating assembly drives the movable sleeve 105 to move vertically, so that the movable sleeve 105 drives the vertical clamping block 103 to move vertically synchronously along the limit blocks 104, so that the distance between the horizontal clamping block 102 and the vertical clamping block 103 is adjusted and changed, so that the horizontal clamping block 102 and the vertical clamping block 103 can clamp steering gear housings of different sizes, thereby improving the clamping stability and clamping effect of the steering gear housing.

The setting of the anti-slip sleeve 110 can avoid slipping when rotating the wheel 109. When in use, the wheel 109 is rotated, so that the wheel 109 drives the screw rod 108 to rotate, thereby realizing the rotation drive of the screw rod 108.

[0025] In the embodiment, when in use, the steering gear housing is placed between the lateral clamping blocks 102 on both sides, then the distance between the lateral clamping blocks 102 and the vertical clamping blocks 103 is adjusted according to the size of the steering gear housing, the wheel disc 109 is rotated, the screw rod 108 is rotated under the rotation cooperation of the rotating shaft 107 and the lateral clamping blocks 102, the rotation of the screw rod 108 drives the movable sleeve 105 to move vertically along the screw rod 108 through the threaded cooperation with the movable sleeve 105, the movement of the movable sleeve 105 drives the vertical clamping blocks 103 to move synchronously along the limiting blocks 104, so that the distance between the vertical clamping blocks 103 and the lateral clamping blocks 102 is adjusted to the appropriate position, then the lateral clamping blocks 102 on both sides and the vertical clamping blocks 103 on both sides are simultaneously moved towards the middle through the driving of the pushing assembly, until the steering gear housing is fixed, so that the lateral clamping blocks 102 and the vertical clamping blocks 103 can clamp steering gear housings of different sizes by adjusting the distance between the lateral clamping blocks 102 and the vertical clamping blocks 103, thereby improving the clamping stability and clamping effect of the steering gear housing.

The movable rack 202 is welded on the transverse clamping block 102. When in use, the movable rack 202 is pushed to move in the slide 204 by the transmission component, so that the transverse clamping block 102 moves under the sliding cooperation of the dovetail block 201 and the dovetail groove 203, thereby achieving the movement effect of the transverse clamping block 102.
