Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.

Embodiment a leg stretching frame

The embodiment discloses a leg stretching frame, as shown in fig. 1 and 2, comprising a base 1, two stretching rods 2 and a rotating rod 3. Wherein, the border department at base 1 evenly opens there are a plurality of fixed orificess 101, and base 1 is fixed on ground through a plurality of bolts that run through a plurality of fixed orificess 101 respectively.

Two stretching rods 2 are hinged on the upper end surface of the base 1 at intervals, and one end of each stretching rod 2, which is far away from the hinged position, is hinged with a leg fixing piece. Wherein, the leg fixing member includes a leg placing plate 202 whose cross section is arc-shaped, and for the comfort of placing the leg, as shown in fig. 3, a sponge layer 204 is laid on the surface of the leg placing plate 202 contacting with the leg, a layer of artificial leather 205 is wrapped outside the sponge layer 204, binding bands 203 are sewn on both sides of the artificial leather 205, and two corresponding binding bands 203 are used for binding and fixing the leg placed on the leg fixing member.

The vertical setting of bull stick 3 and one end are rotated with base 1 and are connected, and bull stick 3 sets up between two tensile poles 2, and threaded connection has thread bush 5 on bull stick 3. A hinged seat 201 is fixedly welded in the middle of each stretching rod 2, and a connecting rod 4 is arranged between each stretching rod 2 and the threaded sleeve 5. One end of each connecting rod 4 is hinged with the threaded sleeve 5, the other end is hinged with the corresponding hinge seat 201 of the stretching rod 2, and the axes of the two connecting rods 4 and the rotating rod 3 are positioned on the same plane. In order to facilitate the trainees to adjust the angle of the two legs to be opened at any time according to the requirements of the trainees, an operation hand wheel 301 is installed at one end of the rotating rod 3, which is far away from the base 1. The training personnel are through rotating the operating handle so that bull stick 3 rotates, and threaded sleeve 5 is along the motion of vertical direction under the rotation of bull stick 3 to realize that two stretching poles 2 are the motion of opening and shutting along the axis of bull stick 3.

In order to avoid waist fatigue of the trainee, a bent rod 601 is fixedly welded on the threaded sleeve 5, and one end of the bent rod 601, which is far away from the threaded sleeve 5, extends upwards in the vertical direction and forms an extending end.
