[0045] The support swing arm 6 is arranged above the mounting groove 2. A swing electric push rod 7 is arranged between the side wall of the support swing arm 6 and the mounting groove 2. Both ends of the swing electric push rod 7 are hinged with push rod hinge seats 8 through shaft holes. Two sets of push rod hinge seats 8 are respectively fixed in the mounting groove 2 and on the outer side wall of the support swing arm 6. The support swing arm 6 is provided with a mounting opening 9, and a retractable discharge push rod 10 is installed in the mounting opening 9.

[0046] The flaring frame 12 is arranged in the mounting opening 9, and the flaring frame 12 is connected to the supporting swing arm 6 through a screw assembly 11.

The arc center of the guide groove 5 coincides with the rotation axis of the lower swing arm 20. When the swing electric push rod 7 is retracted or extended, the supporting swing arm 6 is driven to rotate around the rotation axis of the lower swing arm 20 and the supporting hinge seat 3. The coincidence of the arc center and the rotation axis makes it easy for the guide slider 21 to slide stably in the guide groove 5.

[0049] In some embodiments, Figure 3 As shown, the support swing arm 6 is located between the two groups of guide plates 4, and guide sliders 21 are fixedly connected to the two outer walls of the support swing arm 6 close to the two groups of guide plates 4.

[0050] In some embodiments, Figure 2 and Figure 3 As shown, the telescopic end of the retractable and discharge push rod 10 is fixedly connected with a driving rod 23, and a pull rope 19 is fixedly connected to the driving rod 23. The other end of the pull rope 19 is fixedly connected to the movable spring seat 14, and the pull rope 19 passes through the fixed spring seat 13 and the thrust spring 15.

[0052] Furthermore, if Figure 4 As shown, the upper part of the flaring frame 12 is flared, and an avoidance opening 25 is opened on the side wall of the flaring frame 12. The V-shaped clamp arm 17 passes through the avoidance opening 25. The corner end of the V-shaped clamp arm 17 is hinged with a clamp arm hinge seat 26, and the clamp arm hinge seat 26 is fixedly connected to the outer side wall of the flaring frame 12 to facilitate the rotation of the V-shaped clamp arm 17 and prevent it from scratching the flaring frame 12 during rotation.

[0053] Furthermore, if Figure 5 As shown, the clamp assembly 18 includes a clamp 181, which is arc-shaped. The outer convex surface and the inner concave surface of the clamp 181 are respectively fixed with a clamp hinge seat 182 and an anti-slip pad 183. The clamp hinge seat 182 is hinged to the end of the V-shaped clamp arm 17 away from the connecting rod 16, so that the relative clamp 181 can clamp and fix the column jack.

[0054] Preferably, if Figure 6 As shown, the anti-skid pad 183 is composed of multiple groups of anti-skid balls distributed in an array, which improves the stability of the column jack when clamped and prevents slipping.

[0055] Preferably, if Figure 5 As shown, a spring groove 27 is provided on one side arm of the V-shaped clamp arm 17 away from the connecting rod 16, and a pull ring 28 is fixedly connected inside the spring groove 27 and on the outer convex surface of the clamp plate 181. A limit spring 29 is hooked between the two groups of pull rings 28. The limit spring 29 is provided to connect the V-shaped clamp arm 17 and the clamp plate 181, so as to limit the clamp plate 181 when the column jack 30 is not clamped, so as to prevent the clamp plate 181 from rotating to the side away from the spring groove 27 due to inertia, so that the arc-surface concave parts of the two corresponding groups of clamp plates 181 can also remain relative when the clamping work is not performed.

[0056] A specific application of the present application is: the utility model is suitable for positioning during assembly of a column jack. When in use, the swinging electric push rod 7 is started to drive the supporting swing arm 6 to rotate around the rotation axis of the supporting hinge seat 3, and the guide slider 21 on the outer wall of the supporting swing arm 6 slides in the guide groove 5. The angle position of the clamping plate 181 is adjusted according to the position and angle of the column jack 30, so that the clamping plate 181 is rotated to the outside of the outer wall of the column jack 30, and then the retractable electric push rod 10 is started to contract, and the pull rope 19 is driven to move downward through the driving rod 23, and the movable spring seat 14 moves toward the direction of the fixed spring seat 13 to compress the thrust spring 15, and the movable spring seat 14 drives the V-shaped clamp arm 17 to rotate through the connecting rod 16, and the V-shaped clamp arm 17 drives the clamping plate assembly 18 to swing so that the clamp 181 clamps and fixes the column jack 30, which is convenient for clamping and fixing column jacks of different diameters. Then, the device can be moved to the working position as a whole through the rollers at the bottom of the base 1 (not shown) or the base 1 is placed on a trolley to position the column jack assembly; when the column jack 30 has been installed, the clamping plate 181 is needed to release it, and at this time, the retractable discharge push rod 10 is started to extend, driving the rod 23 to lose the pulling force on the pull rope 19. Due to the reset thrust of the thrust spring 15, the thrust spring 15 pushes the movable spring seat 14 to move away from the fixed spring seat 13, and the pull rope 19 remains in a straightened state. The connecting rod 16 pushes the V-shaped clamp arm 17 to rotate in the opposite direction, the clamping plate 181 is separated from the column jack 30, and then the device is moved away.
