In some embodiments, the number of moving wheels can also be more than four, as long as it can achieve stable support for the base 1 and ensure its mobility.

[0024] A lifting connecting plate 3 is provided above the base 1, a supporting plate 4 with an adjustable tilt angle is provided above the connecting plate 3, and a movable clamping assembly 6 is provided on the upper end of the supporting plate 4 to clamp the electric torque wrench. Figure 3 As shown, the clamping assembly 6 includes a mounting plate 61 that is slidably connected to the support plate 4, and two clamping plates 62 that can slide synchronously in opposite directions are provided on the mounting plate 61. A accommodating cavity for placing the electric torque wrench is formed between the two clamping plates 62. The two clamping plates 62 are close to each other to clamp the handle of the electric torque wrench; when in use, the sleeve on the electric torque wrench is aligned with the bolt by controlling the lifting and lowering of the connecting plate 3, the tilting of the support plate 4 and the steering movement of the base 1, and then the mounting plate 61 is controlled to slide on the support plate 4, and the sleeve of the electric torque wrench is engaged with the bolt head to apply a specified torque to the bolt for locking.

[0025] Furthermore, in this embodiment, the two clamping plates 62 are slidably connected to the mounting plate 61. The mounting plate 61 is provided with two first fixing plates 611. A screw rod 63 is rotatably connected between the two first fixing plates 611. Figure 4 As shown, the two ends of the screw rod 63 are respectively provided with a first external thread 631 and a second external thread 632 of opposite rotation direction and equal pitch, and the two clamps 62 are respectively threadedly connected to the corresponding first external thread 631 and the second external thread 632; a motor is provided on one of the first fixed plates 611 to drive the screw rod 63 to rotate, so as to realize the synchronous reverse sliding of the two clamps 62; in addition, in order to ensure the clamping stability of the electric torque wrench, the screw rod 63 needs to have self-locking properties, that is, the thread lead angles of the first external thread 631 and the second external thread 632 are both less than the equivalent friction angle. In specific use, the method of driving the two clamps 62 to slide synchronously in the opposite direction includes but is not limited to the screw rod 63 in this embodiment, and the two clamps 62 can also be driven to slide synchronously in the opposite direction by providing two cylinders on the mounting plate 61. In addition, a card slot 621 is provided on the clamp 62, and the card slot 621 can cooperate with the handle of the electric torque wrench to improve the stability of the clamping.

[0026] In this embodiment, if Figure 2As shown, two second fixing plates 41 are provided at the upper end of the support plate 4, and two guide rods 42 are fixed between the two second fixing plates 41. The two guide rods 42 both pass through the mounting plate 61 and are slidably connected thereto, thereby realizing a sliding connection between the mounting plate 61 and the support plate 4; in addition, a spring 7 is sleeved on the guide rod 42, and the two ends of the spring 7 are respectively in contact with one of the second fixing plates 41 and the mounting plate 61. Under the elastic force of the spring 7, the mounting plate 61 is tightly attached to the other second fixing plate 41, thereby preventing the mounting plate 61 from sliding freely on the support plate 4 during the movement of the electric torque wrench driven by the base 1; after the sleeve of the electric torque wrench is aligned with the bolt, the elastic force of the spring 7 is overcome by manually pushing the mounting plate 61, so that the sleeve of the electric torque wrench is engaged with the bolt and the tightening action is completed.

[0027] In this embodiment, a first hydraulic cylinder 2 is provided on the base 1 to directly drive the connection plate 3 to rise and fall; in other embodiments, a linear drive component such as a cylinder or a telescopic rod can also be provided on the base 1 to directly drive the connection plate 3 to rise and fall. An adjustment component 5 is provided on the upper end of the connection plate 3 to adjust the inclination angle of the support plate 4 to adapt to the bolt locking task on different inclined surfaces; Figure 5 and Figure 6 As shown, a connecting seat 43 is fixed to the lower end of the support plate 4, and the adjustment assembly 5 includes a support rod 51 fixed to the upper end of the connecting plate 3, and the support rod 51 is hinged to the connecting seat 43, so that the support plate 4 can be flipped and adjusted around the connecting seat 43; a T-shaped slide groove 44 is provided at the lower end of the support plate 4, and a T-shaped slider 54 is slidably connected in the T-shaped slide groove 44, and the sliding direction of the slider 54 is parallel to the sliding direction of the mounting plate 61, and a second hydraulic cylinder 52 is fixed to the upper end of the connecting plate 3, and a connecting block 53 is fixed to the end of the driving shaft of the second hydraulic cylinder 52, and the connecting block 53 is hinged to the slider 54; by controlling the lifting and lowering of the driving shaft of the second hydraulic cylinder 52, the support plate 4 can be driven to flip around the connecting seat 43, thereby realizing the adjustment of the inclination angle of the support plate 4.

[0028] The working principle of the present invention is as follows: by providing a movable wheel at the lower end of the base 1 to achieve the movement and steering of the base 1, a connecting plate 3 that can be raised and lowered is provided above the base 1, and a support plate 4 with an adjustable tilt angle is provided on the connecting plate 3, and a slidable clamping assembly 6 is provided on the support plate 4 to clamp and fix the electric torque wrench. When in use, by controlling the raising and lowering of the connecting plate 3, the tilting of the support plate 4, and the steering movement of the base 1, the sleeve on the electric torque wrench is aligned with the bolt, and then the mounting plate 61 is controlled to slide on the support plate 4, and the sleeve of the electric torque wrench is engaged with the bolt head to apply a specified torque to the bolt for tightening. Compared with the prior art of manually operating the electric torque wrench with a handheld electric torque wrench, the labor intensity of the operator is greatly reduced. By providing a spring 7 between one of the fixing plates 41 and the mounting plate 61, the mounting plate 61 is tightly attached to the other fixing plate 41, thereby preventing the mounting plate 61 from sliding freely on the support plate 4 when the base 1 drives the electric torque wrench to move.
