As shown in figures 1-5, a stretching device for physical education, including backup pad 1, the top fixed mounting of backup pad 1 has box 2, the side of box 2 has slide bar 3 that is no less than two and is on a parallel with backup pad 1 along the length direction of backup pad 1 slides through, the equal joint of one end that every slide bar 3 is located box 2 is in box 2, the equal fixed mounting of one end that every slide bar 3 is located box 2 outside has dog 4, equal fixed mounting has spring 5 and every spring 5 all cup joints on the surface of every slide bar 3 between the side of every dog 4 and box 2, the recess 6 the same with slide bar 3 quantity has been seted up along backup pad 1 length direction on the backup pad 1, trompil 7 has all been seted up along backup pad 1 length direction to the one end that every recess 6 was kept away from box 2, the equal fixed mounting of one end that every slide bar 3 is close to dog 4 has L type bracing piece 8 and every L type bracing piece 8 is on a parallel with the one 7 sliding connection, the equal threaded connection of one end that recess 6 was kept away from to every trompil 7 has threaded rod 9, and the top of backup pad 1 is provided with the baffle 10 that moves together with slide bar 3 and baffle 10 and the laminating of dog 4 at the removal in-process, and the top of backup pad 1 is equipped with handrail 11.

In the embodiment, the stretching device preferentially adopts three slide bars 3, when in physical education, a student sits on the supporting plate 1, both hands hold the handrails 11 tightly, knees are positioned between the baffle 10 and the handrails 11, both feet are placed on the surface of the baffle 10 vertical to the supporting plate 1, at the moment, both legs of the student are in a bending state, because the baffle 10 is attached to the baffle 4, and the spring 5 is connected between the baffle 4 and the outer surface of the box body 2, the student stretches the both legs to push the baffle 10 to push the baffle 4 to approach the box body 2, so that the both legs of the student are in a straight state, at the moment, the spring 5 is in a compression state, then the student releases the thrust on the baffle 10, the baffle 4 and the baffle 10 are pushed under the action of the spring 5 to enable the legs of the student to continue to bend, thereby the legs are convenient to do repeated stretching movement, the slide bars 3 are driven to move while the baffle 4 is pushed, one end of the slide bar 3, the both ends of spring 5 and the fixed surface connection of dog 4 and box 2, in the in-process spring 5 that compresses spring 5 not with the outer surface contact of slide bar 3, spring 5 can not receive the frictional force on slide bar 3 surface when receiving compression and release elasticity and make spring-back effect of spring 5 better, when student's shank strength difference is great, move to backup pad 1 inside through rotatory threaded rod 9, threaded rod 9 will contact and promote L type bracing piece 8 to be close to box 2 with the one end contact of L type bracing piece 8 at the in-process that moves to backup pad 1 inside as shown in figure 4, thereby L type bracing piece 8 and slide bar 3 fixed connection make slide bar 3 and dog 4 remove and compress spring 5 fixedly, the student again when tensile after the compression is accomplished because the elasticity that baffle 10 received diminishes and make the required shank strength of both feet when promoting baffle 10 reduce, the device can use threaded rod 9 to compress one or two springs 5 as required thereby be fit for more legs and fix to one or two springs 5 The students with different strength use the utility model.

Specifically, the armrest 11 includes two supporting rods 12, one end of each supporting rod 12 is connected to the supporting plate 1 through a screw thread, and a handle 13 parallel to the supporting plate 1 is fixedly mounted on one end of each supporting rod 12 away from the supporting plate 1 through a bearing.

In this embodiment, one end of the supporting rod 12 is connected with the supporting plate 1 through a screw thread and the other end is connected with the handle 13 through a bearing, and the handrail 11 can be detached and replaced conveniently by rotating the supporting rod 12 with both hands.

Specifically, the top of the supporting plate 1 is provided with threaded holes 14 distributed in an array, and the threaded holes 14 are used for adjusting the distance between the armrest 11 and the baffle 10.

In this embodiment, dismantle handrail 11 through rotatory branch 12, fix handrail 11 through the screw hole 14 of different positions, make the student of different heights more comfortable that the hand was placed when using the device again.

Specifically, two T type chutes 15 parallel to the groove 6 are formed in the support plate 1, two T type sliders 16 are connected inside the two T type chutes 15 in a sliding mode, and the two T type sliders 16 are fixedly connected with the baffle 10.

In this embodiment, the two T-shaped sliding grooves 15 are respectively located at two sides of the three grooves 6, the baffle 10 moves on the supporting plate 1, and the baffle 10 is more stable in the moving process through the cooperation of the T-shaped sliding blocks 16 and the T-shaped sliding grooves 15.

Specifically, two foot sleeves 17 which are positioned at the same height are fixedly arranged on the outer surface of the baffle plate 10 close to the handrail 11.

In this embodiment, the leg sleeves 17 are attached to the barrier 10, so that the student places his or her legs in the leg sleeves 17 when the student pulls the barrier 10, and the legs are less likely to slide on the barrier 10 when the student pushes the barrier 10, thereby further stabilizing the contact between the legs and the barrier 10.
