[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a crane mounting frame, including a mounting base 1 for installing and fixing the crane body 2. The mounting base 1 may also be equipped with counterweights (not shown in the figure) to ensure safe and stable lifting when used alone. This is a relatively mature technology and will not be described in detail here. A mounting block 6 with mounting components is welded to the rear end of the mounting base 1. The mounting block 6 has mounting holes 12 for easy installation and fixing to the vehicle body or other equipment using screws, etc. To ensure stability, a rotating groove 5 is provided at the front end of the mounting base 1. An extension rod 4 is symmetrically arranged inside the rotating groove 5 via a rotating component. The extension rod 4 is fitted with a sleeve 3 via an adjusting component. The sleeve 3 has an opening... The threaded hole 18 with a fixed support component allows for easy installation and fixing with screws or the mounting hole 12, ensuring stability and firmness during use. To facilitate rotation and adjustment of the opening angle, ensuring stability and easy storage, the rotating groove 5 has a rotating rod 8 with a rotating component. The rotating rod 8 has two sets of rotating plates 14, one above the other, which are welded and fixed to the two extension rods 4 respectively. The top of the rotating rod 8 passes through the rotating groove 5 and extends upwards, where it is threadedly engaged with a fastening nut 9. A washer is also fitted on the rotating rod 8. After being tightened by the fastening nut 9, the rotating rod 8 and the rotating plates 14 are firmly fixed in position to prevent rotation and not affect use or storage after unfolding.

[0023] Please see Figures 1-5To facilitate independent use and easy pushing, the fixed base 1 has symmetrically welded connecting rods 10 of auxiliary components at both ends. An auxiliary wheel 11 is installed under the connecting rod 10, and a roller 7 is installed at the end of the sleeve 3 for easy pushing and support during use. An adjusting screw 13 is threaded into the threaded hole 18 of the sleeve 3. A fixed support foot 20 is welded to the bottom of the adjusting screw 13, and an anti-slip pad 17 is adhered to the bottom of the fixed support foot 20. The anti-slip pad 17 has anti-slip textures and provides support when used alone. When installed on other equipment, the adjusting screw 13 is removed, and the sleeve 3 is installed and fixed to the equipment using screws that engage with the threaded hole 18. For adjustment as needed, a sliding cavity 19 of the adjusting component is provided inside the sleeve 3. The extension rod 4 slides within the sliding cavity 19. A positioning screw 16 is threaded into the end of the sleeve 3 away from the roller 7, and positioning holes 15, which are equidistant from the positioning screw 16, are provided on the extension rod 4 for easy positioning and fixing after adjustment.

[0024] Working principle: When this utility model is used, if it needs to be assembled on a vehicle body or other equipment, the adjusting screw 13 is removed from the threaded hole 18, and then the sleeve 3 is rotated. The sleeve 3, in conjunction with the rotating rod 8, can rotate within the rotating groove 5. After adjusting to a suitable position, the fastening nut 9 is tightened to position and fix the sleeve 3. It can then be installed and fixed to the equipment using screws or similar means, in conjunction with the mounting hole 12 and the threaded hole 18, without affecting subsequent operation. When it needs to be used alone, it can be moved by pushing the crane body 2, in conjunction with the roller 7 at the end of the sleeve 3 and the auxiliary wheel 11 under the connecting rod 10. After moving to the designated location, if the overall length needs to be moved, it can be adjusted by rotating... Loosen the positioning screw 16 to release its fixation to the extension rod 4, allowing the sleeve 3 to be pushed and pulled to adjust the overall length. Then, tighten the positioning screw 16 to fix it in place with the positioning hole 15. When adjusting the opening angle, loosen the fastening nut 9 to release its fixation to the rotating rod 8. By turning the two sleeves 3, the extension rod 4 and the rotating plate 14 can be rotated, thus adjusting the opening angle. After adjustment, tighten the fastening nut 9 to fix it in place. Then, screw the adjusting screw 13 into the threaded hole 18 and rotate the adjusting screw 13 to rotate the fixed support 20. With the help of the anti-slip pad 17, it can be supported and fixed to ensure stability and firmness during use.
