The invention discloses a ladder with a horizontal extension function. The ladder comprises two ladder bodies; treading mechanisms are arranged at the ends, close to each other, of the inner sides of the two ladder bodies correspondingly; sliding grooves are formed in the left ends and the right ends of the two ladder bodies correspondingly; sliding blocks are slidably connected to the interiors of the two sliding grooves correspondingly; and each treading mechanism internally comprises a first fixed block, a bearing block, a first connecting block, a first cylinder, a first fixed rod, a first rolling shaft and a second fixed block. Through the arrangement of the second fixed blocks, when the treading mechanisms are treaded through the gravity of a person, the second fixed blocks arranged on the two sides can stretch out of the two sides of the first fixed block due to the gravity, and a plane for the foot sole of a worker is enlarged, so that the possibility of falling is reduced; the friction force of the foot sole can be increased through an anti-skid device, so that the phenomenon of slipping of the foot sole is reduced; and the first fixed rods are returned through elastic ropes when no pressure exists at the tops of the bearing blocks.
本发明公开了一种具有水平伸出的梯子，包括梯子，所述梯子的数量为两个，两个所述梯子内侧相互靠近一端均分别设置有踩踏机构，两个所述梯子左右端均分别开设有滑槽，两个所述滑槽内部均分别滑动连接有滑块；所述踩踏机构内部包括固定块一、承重块、连接块一、圆柱一、固定杆一、滚轴一和固定块二，本发明通过设置固定块二，通过人自身的重力对踩踏机构进行踩踏时，会将两侧设置的固定块二会因为重力的关系从固定块一的两侧伸出，使工作人员脚底平面增大从而减少会掉落的可能，通过防滑装置，可增加脚底的摩擦力以此来减少脚底打滑的现象，通过弹力绳，在承重块顶部没有压力时对固定杆一进行回位的效果。
