[0012] Preferably, the combined bracket includes a snap-in seat and a cross arm; the snap-in seat is inserted into the right side of the base and connected through a pin shaft; there is at least one cross arm, which is connected to one side of the snap-in seat, and a snap-in block is provided on the cross arm, and a second support leg is provided on the block.
[0013] Preferably, snap-in grooves are symmetrically provided on both sides of the cross arm.
[0014] Compared with the prior art, the utility model has the following advantages:
[0015] 1. By unfolding the first arm and installing the first support leg, the contact area with the ground can be increased, thereby improving the overall stability during lifting and preventing tipping. At the same time, the design of the extension arm can further extend the contact position, improve stability, and meet the needs of indoor lifting;
[0016] 2. When working in the balcony area, if there are fixed bolts reserved on the balcony, you can pull the combined shaft to extend outward, then rotate the first arm body to a vertical state, connect the first arm body with the fixed bolts, and realize the positioning of the base, which is applicable to a variety of scenarios;
[0017] 3. For balconies or narrow areas, the base can be positioned by supporting the combined bracket in contact with the wall to meet different usage environments. The combined bracket and the base are detachably connected, which is convenient for installation and use according to needs and improves operability.
[0018] 4. The structural design of the combined axis only provides horizontal rotation of the first arm before extending to both ends, and cooperates with the first support foot to contact the ground. After extending outward for a certain distance, the restriction can be released so that the first arm can rotate in a circular direction to achieve connection with the fixing bolts on the wall, and the overall structural bridge deck improves its own operability.
