The first embodiment is as follows:

a wood chair backrest tool comprises a workbench 1, a cylinder 2, a first positioning block 10, a second positioning block 11, a third positioning block 12 and a limiting block 13, wherein the cylinder 2, the first positioning block 10, the second positioning block 11, the third positioning block 12 and the limiting block 13 are fixedly mounted on the workbench 1, the cylinder 2 and the first positioning block 10 are located in the front half section of the workbench 1, the second positioning block 11 and the third positioning block 12 are located between the cylinder 2 and the first positioning block 10 and located in the rear half section of the workbench 1, the limiting block 13 is located between the second positioning block 11 and the third positioning block 12 and located behind the second positioning block 11 and the third positioning block 12, the first positioning block 10 comprises a positioning surface and a blocking surface, an included angle between the positioning surface and the blocking surface is larger than 90 degrees, and the extending direction of an extending rod on the cylinder 2 is in the left-right direction; wooden armchair back includes integrated into one piece's first handrail board 30, second handrail board 31 and back board 32, first handrail board 30 and second handrail board 31 are the plane board and symmetric distribution in the left and right sides of back board 32, back board 32 is the arc.

Wherein, the positioning surface is a surface of the first positioning block 10 which is abutted against the end surface of the first armrest plate 30 when the chair backrest is placed; the blocking surface is a surface of the first positioning block 10 which is abutted against the side surface of the first armrest plate 30 when the surrounding chair backrest is deformed by the cylinder 2.

In this embodiment, a fourth positioning block 14 and a fifth positioning block 15 are further provided, the fourth positioning block 14 is close to the first positioning block 10, and the fifth positioning block 15 is close to the cylinder 2.

In this embodiment, the stopper 13 is an elongated shape.

In this embodiment, the extending end of the extending rod is further provided with a rubber sleeve; this prevents the projecting rod from causing a pressing damage to the first balustrade panel 30.

The process of the wooden armchair back rest to install the connecting piece 4 shown in figure 3 is as follows:

the method comprises the following steps: placing the backrest of the wooden armchair on the workbench 1, enabling the first handrail plate 30 to abut against the positioning surface, and enabling the backrest plate to abut against the second positioning block 11 and the third positioning block 12; it should be noted that, at this time, the connecting line of the end surface and the side surface of the first armrest plate 30 should also coincide with the connecting line of the positioning surface and the blocking surface, so that when the cylinder 2 presses the surrounding chair backrest, the surrounding chair backrest has a pivot point for rotation;

step two: an extension rod of the cylinder 2 extends out and presses the second handrail plate 31 to enable the surrounding chair backrest to deform, and finally the side face of the first handrail plate 30 is enabled to be tightly attached to the blocking face, and the backrest plate is abutted to the limiting block 13; it should be noted that, in this process, in order to ensure that the seat back of the seat chair is in the elastic deformation range, the deformation of the seat back of the seat chair should not be too large, that is, the rotation angle of the second armrest plate 31 should not be too large, so the included angle between the positioning surface and the blocking surface should be smaller than 100 °, and in order to ensure that the pressure between the extension bar and the first armrest plate 30 is not too large in this state, the contact area between the extension bar and the first armrest plate 30 should be fully ensured, so the extension direction of the extension bar on the cylinder 2 should be perpendicular to the blocking surface.

Step three: placing a plurality of connecting pieces 4 at mounting holes of the surrounding chair backrest along a second positioning block 11, a third positioning block 12, a fourth positioning block 14 and a fifth positioning block 15 respectively, and mounting the plurality of connecting pieces 4 on the surrounding chair backrest through fasteners; the second positioning block 11, the third positioning block 12, the fourth positioning block 14 and the fifth positioning block 15 are all strip-shaped, so that the plurality of connecting elements 4 can slide along the second positioning block 11, the third positioning block 12, the fourth positioning block 14 and the fifth positioning block 15, respectively.

Step four: the extension rod of the air rod extends back and draws out the back of the surrounding chair.

Like this, can simulate out the shape of surrounding chair back when assembling with the bedplate through above-mentioned frock, shape after the deformation promptly, then install connecting piece 4 on the surrounding chair back, and then ensure that the bottom surface of a plurality of connecting piece 4 all is in same horizontal plane to improve the steadiness of surrounding chair back installation.
