[0021] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a high-efficiency and accurate inspection tool for detecting shock absorber piston rod runout includes a base plate 1, and also includes a support plate 2, which is arranged on the base plate, and the top of the support plate is provided with a roller 21 for contacting the circumferential outer wall of the workpiece 9; a mounting plate 3, which is arranged on the base plate, and the mounting plate is provided with a driving plate 31 that can rotate along its own axis, and the driving plate is provided with an insert block 311 for inserting into the U-shaped groove of the workpiece and driving the workpiece to rotate along its own axis; a fixing plate 4, which is provided on the base plate, and a dial indicator 41 is provided on the fixing plate, and the top rod of the dial indicator is used to contact the circumferential outer wall of the workpiece; a clamping plate 5, which is provided on the base plate, includes a first position in contact with the circumferential outer wall of the workpiece and a second position separated from the circumferential outer wall of the workpiece. Before use, the clamping plate is opened and the workpiece is placed in. There are more than two rollers on each support plate, which are in contact with the outer end face of the workpiece. The insert on the drive plate is inserted into the U-shaped groove of the workpiece to drive the workpiece to move. After installation, the clamping plate is pressed down to prevent the workpiece from jumping during rotation, and then the workpiece is rotated to read the value through the dial indicator.

[0022] In this embodiment, as shown in the figure, the bottom plate is further provided with a base 51, on which the pressing plate is rotatably mounted. The base is further provided with a rotatable handle 52, which is used to rotate the pressing plate. Rotating the handle drives the pressing plate to rotate and switch positions, resulting in a relatively simple structure.

[0023] In this embodiment, as shown in the figure, the handle is provided with a cam 521 for driving the pressing plate to rotate. When the handle rotates, the pressing plate is driven to rotate by the cam. Preferably, when the handle reaches the highest position, the pressing plate will be pressed at the dead point of the handle rotation without hand support.

[0024] In this embodiment, as shown in the figure, the pressing plate is provided with a second roller 53 for contacting the outer wall of the workpiece to prevent damage to the workpiece.

[0025] In this embodiment, as shown in the figure, the base is provided with a slide rail 11, and the bottom of the fixed plate is provided with a slide groove that matches the slide rail, so as to facilitate position adjustment.

[0026] In this embodiment, as shown in the figure, the driving plate includes a rotating shaft, and the rotating shaft passes through the mounting plate and is provided with an operating rod 312. Manually driving the operating rod to move, simultaneously drives the rotating shaft to rotate, and the rotating shaft drives the driving plate to rotate.

[0027] In this embodiment, as shown in the figure, two support plates are provided, which makes the installation more stable.
