[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example 1:

[0029] like Figures 1 to 5 As shown, this embodiment proposes a chair with armrests, including: a seat 1, a support column 2, a slide groove 21, a connecting groove 22, a slide rod 3, an armrest 4, a lifting assembly 5, a support rod 6, a positive and negative lead screw 7, and an adjusting block 71. The support column 2 is fixedly connected to both sides of the seat 1. The upper end of the support column 2 has a slide groove 21, and the front end of the support column 2 has a connecting groove 22. The slide rod 3 is slidably connected inside the slide groove 21. The armrest 4 is rotatably connected to the upper end of the slide rod 3. The lifting assembly 5 is disposed inside the slide groove 21. Two support rods 6 are respectively hinged to the lower front end of the slide rod 3 and the lower front end of the handrail 4. The positive and negative screw rods 7 are set at the lower part of the handrail 4. The two support rods 6 are respectively threaded to the outside of the support rods 6. An adjusting block 71 is fixedly connected to the middle of the outer side of the positive and negative screw rods 7. The lifting assembly 5 controls the slide rod 3 to drive the handrail 4 to rise and fall, thereby controlling the height of the handrail 4. By rotating the adjusting block 71, the positive and negative screw rods 7 can be easily rotated.
