[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1:

[0019] Reference Figure 1-3 A device for preventing a traction plate from falling comprises: a traction seat 2 fixedly connected to a traction frame 1, a rotating hole 202 being provided on the traction seat 2, a rotating shaft 303 being rotatably connected in the rotating hole 202, a traction shaft 301 being fixedly connected to the rotating shaft 303, a traction head 302 being fixedly connected to the traction shaft 301, a first fixing pin 4 and a second fixing pin 401 being fixedly connected to the traction seat 2, a limiting groove being provided between the first fixing pin 4 and the second fixing pin 401, a limiting pin 402 being fixedly connected to the traction shaft 301, and the limiting pin 402 being clamped in the limiting groove.

[0020] The top of the first fixing pin 4 is higher than the top of the second fixing pin 401 , and the vertical length of the rotating hole 202 is greater than the sum of the diameters of the limiting pin 402 and the rotating shaft 303 , so that the limiting pin 402 can be easily placed in the limiting groove.

[0021] There are two groups of traction seats 2 symmetrically arranged, and the two traction seats 2 are connected by a connecting frame 201, which can improve the stability of the limiting fixation of the traction head 302; a limiting plate 3 is fixedly connected to the rotating shaft 303, and the limiting plate 3 is in contact with the connecting frame 201. The setting of the limiting plate 3 facilitates the welding of the traction shaft 301 and the rotating shaft 303, and the setting of the limiting plate 3 facilitates the fit of the traction seat 2 after rotation, and at this time it is convenient to insert the limiting pin 402 into the limiting groove.

[0022] When using this device, refer to Figure 1 The traction head 302 and the traction shaft 301 are arranged horizontally, and the traction frame 1 can be traction-transferred through the traction head 302;

[0023] When the traction head 302 needs to be retracted after traction, the traction shaft 301 is rotated by the rotating shaft 303 so that the traction shaft 301 and the traction head 302 face upward. Figure 2 state;

[0024] It should be noted that when the traction head 302 is pulled and rotated, an upward force is applied to the traction head 302, so that the rotating shaft 303 moves upward in the rotating hole 202. At this time, the limit pin 402 is higher than the top of the second fixing pin 401, so that the limit pin 402 is located above the limit groove. The traction head 302 is released, and the traction head 302, the traction shaft 301, and the limit pin 402 move downward, and the limit pin 402 falls into the limit groove to prevent the traction head 302 from shaking and falling.

[0025] Specifically, the first fixing pin 401, the second fixing pin 402, and the limiting pin 402 can be made of a pin shaft with a length of 6 cm and a thickness of 1 cm, and connected by welding;

[0026] The utility model can limit the traction shaft 301 and the traction head 302 by providing the first fixing pin 4, the second fixing pin 401 and the limiting pin 402 to prevent them from shaking, and has a simple structure and is easy to operate.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
