A positioning strip 16 is fixedly connected to the bottom of the spring 15, and the positioning strip 16 is slidably connected to the receiving groove 14.

[0024] As a technical optimization solution of the utility model, by setting the storage groove 14, the spring 15 and the positioning strip 16, the hard contact between the lower pressure strip 4 and the tatami is converted into soft contact, so that the surface of the tatami can be protected, and the reaction force of the spring 15 can be used to make the positioning strip 16 position the tatami more securely.

[0025] refer to Figure 4 A damper 17 is disposed inside the spring 15 , and two ends of the damper 17 are fixedly connected to the receiving groove 14 and the positioning bar 16 , respectively.

[0026] As a technical optimization solution of the present invention, by setting the damper 17 , the elastic deformation of the spring 15 can be converted into mechanical energy, so that the repeated bouncing of the spring 15 can be suppressed to buffer the attenuation of the natural vibration of the spring 15 .

[0027] refer to Figure 1 and Figure 3 A limiting hole 18 is symmetrically opened on the top of the support bar 10 about the electric push rod 11, and a limiting column 19 is symmetrically fixedly connected to the top of the connecting frame 12, and the limiting column 19 is slidably connected to the limiting hole 18.

[0028] As a technical optimization solution of the present invention, by providing the limiting holes 18 and the limiting columns 19, it can be ensured that the connecting frame 12 can be vertically lifted and lowered, thereby improving its stability during operation.

[0029] refer to Figure 1 and Figure 2 The bottom of the reciprocating motor 6 is fixedly connected to a carrier frame 20, and the carrier frame 20 is fixedly connected to the support frame 2. The bottom of the carrier frame 20 is symmetrically fixedly connected to a reinforcing bar 21, and the reinforcing bar 21 is fixedly connected to the support frame 2.

[0033] The working principle and use process of the utility model are as follows: when the staff uses the mat stretching machine to stretch the tatami mat, first the device is connected to an external power supply, and then one end of the tatami is placed under the positioning bar 16. At this time, it should be noted that the tatami mat surface needs to face upward, and then the electric telescopic rod 3 is started to drive the lower pressing bar 4 to descend, thereby driving the positioning bar 16 to squeeze one end of the tatami mat surface. At this time, the spring 15 and the damper 17 are compressed, and the reaction force of the spring 15 is used. The positioning strip 16 can make the tatami more securely positioned, so that tatami of different thicknesses can be positioned. Then, the electric push rod 11 is started to drive the connecting frame 12 to descend, so that the stretching roller 13 fits the tatami surface. Then, the reciprocating motor 6 is started to drive the threaded rod 7 to rotate, so that the threaded block 8 can move. At this time, since the roller 23 on the L-shaped strip 9 rolls in the rolling groove 22, the threaded block 8 can only move linearly, so that the stretching roller 13 can be driven to stretch the tatami surface.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
