[0014] More preferably, the bottom of the sliding mounting portion is provided with an inwardly extending annular extension;

[0015] The annular extension is longitudinally slidably connected to the sliding portion;

[0016] The limiting part is longitudinally slidably connected to the sliding mounting part;

[0017] The outer diameter of the limiting part is larger than the outer diameter of the sliding part, and the outer diameter of the supporting ball part is larger than the outer diameter of the sliding part.

[0018] It facilitates the longitudinal sliding connection between the buffer foot and the mounting sleeve.

[0019] More preferably, the outer diameter of the buffer spring is smaller than the outer diameter of the supporting ball.

[0021] More preferably, the upper end of the buffer spring abuts against the lower side of the sliding mounting portion, and the lower end of the buffer spring abuts against the supporting ball portion.

[0022] More preferably, the stretcher body further includes a stretcher cloth, which has a notch for exposing the main support rod;

[0023] The elastic support foot is installed in the support main rod area directly opposite the notch.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. When this utility model is placed on the ground, it is supported by a supporting ball, thereby suspending the main support rod and the hand handle in the air, which allows for quick retrieval of the hand handle and facilitates the transfer of work.

[0026] 2. The support ball can extend and retract via a buffer spring, reducing the impact force when the entire unit contacts the ground. Furthermore, the support ball can slide on smooth surfaces, facilitating placement and movement for operation. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] See Figures 1 to 4 Specific Embodiment 1: A stretcher with elastic support feet includes a stretcher body, which includes a stretcher rod. The stretcher rod includes a supporting main rod 1, and hand handles 2 are installed at both ends of the supporting main rod 1 along its length. The stretcher rod also includes elastic support feet. At least two elastic support feet are installed along the length of the supporting main rod 1. Each elastic support foot includes a mounting sleeve, a buffer spring 10, and a buffer foot. The mounting sleeve includes a mounting sleeve part 4 for fixing to the outside of the supporting main rod 1 and a sliding mounting part 5 for longitudinally slidingly connecting the buffer foot. The mounting sleeve part 4 and the sliding mounting part 5 are arranged vertically and fixedly connected. The buffer foot includes a limiting part 7, a sliding part 8, and a supporting ball part 9 connected sequentially from top to bottom. A buffer spring 10 is sleeved on the outside of the sliding part 8. The limiting part 7 is longitudinally slidably disposed within the sliding mounting part 5. A buffer spring 10 is sandwiched between the sliding mounting part 5 and the supporting ball part 9.

[0034] Two mirror-symmetrically arranged elastic support feet are installed along the length of the main support rod 1.

[0035] The mounting sleeve 4 is welded and fixed to the supporting main rod 1. The mounting sleeve 4 and the sliding mounting part 5 are welded together; the mounting sleeve 4 is a sleeve structure, and the central axis of the sleeve structure is parallel to the central axis of the supporting main rod 1 and perpendicular to the central axis of the sliding mounting part 5.

[0036] The bottom of the sliding mounting portion 5 has an inwardly extending annular extension; the annular extension is longitudinally slidably connected to the sliding portion 8; the limiting portion 7 is longitudinally slidably connected to the sliding mounting portion 5; the outer diameter of the limiting portion 7 is larger than the outer diameter of the sliding portion 8, and the outer diameter of the supporting ball portion 9 is larger than the outer diameter of the sliding portion 8. This facilitates the longitudinal sliding connection between the buffer foot and the mounting sleeve. The sliding mounting portion 5 has an inner hole 6 for slidingly connecting the limiting portion 7. The inner diameter of the inner hole is larger than the inner diameter of the annular extension.

[0037] The outer diameter of the buffer spring 10 is smaller than the outer diameter of the support ball portion 9. The upper end of the buffer spring 10 abuts against the lower side of the sliding mounting portion 5, and the lower end of the buffer spring 10 abuts against the support ball portion 9.

[0038] The main body of the stretcher also includes a stretcher cloth 3, which has a notch for exposing the main support rod 1; the elastic support feet are installed in the area of ​​the main support rod 1 directly opposite the notch.

[0039] When assembling the elastic support foot, firstly, the limiting part 7 and the sliding part 8 are fixedly connected, and then the sliding mounting part 5 is passed through it. The sliding mounting part 5 is then welded and fixedly connected to the mounting sleeve 4. A buffer spring 10 is fitted onto the area outside the sliding part that exposes the sliding mounting part 5. Then, the support ball part 9 is fixedly connected to the sliding part 8.

[0040] During assembly, the mounting sleeves of the elastic support feet are slid into the main support rod 1, and then the mounting sleeves are welded and fixed to the main support rod. Then, the stretcher cloth 3 is installed on the main support rod 1, and hand handles 2 are installed at both ends of the main support rod 1.

[0041] This invention incorporates elastic support feet, allowing the main support pole 1 to remain suspended when the stretcher pole is placed on the ground, enabling quick access to the handle 2 and facilitating work transfer. The elastic support feet also include cushioning springs 10 to absorb the impact force on the ground upon placement.

[0042] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
