DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0024] according to Figure 1-5 As shown, a high and low bar 2 for easy height adjustment includes a high bar 1 and a low bar 2, wherein the high bar 1 and the low bar 2 are respectively mounted on a column 3 via adjustment components at both ends, wherein the adjustment component includes a slider 4 slidably connected to the column 3, wherein the slider 4 is rotatably connected to a lever via a connecting column 5, wherein one end of the connecting column 5 away from the lever is cooperatively connected to an insert block 6, wherein the insert block 6 is slidably connected to the slider 4, and a slot 7 cooperating with the insert block 6 is provided on the side wall of the column 3.

[0025] In the above specific embodiment, when the height of the lever needs to be adjusted, the lever is screwed, and the lever drives the connecting column 5 to rotate. The connecting column 5 is connected with the plug block 6. The rotation of the connecting column 5 drives the plug block 6 to move laterally. When the plug block 6 is inserted into the slot 7, the lever can be fixed. When the plug block 6 is out of the slot 7, the height of the lever can be adjusted.

[0026] A screwing portion is provided at the end of the lever, and an anti-slip layer 21 is provided on the outer wall of the screwing portion, so that the user can drive the lever to rotate by turning the screwing portion.

[0027] The slider 4 is provided with a slide groove 8, and the plug block 6 is slidably connected to the slider 4 via the slide groove 8. The connecting column 5 is connected to the plug block 6 through threaded cooperation. The slide groove 8 is a square structure. By rotating the connecting column 5, the connecting column 5 and the plug block 6 are threadedly connected. At the same time, due to the limitation of the square groove, the plug block 6 can only move horizontally. The lever can be installed and disassembled by rotating the screwing part.

[0028] The outer wall of the connecting column 5 is sleeved with a locking sleeve 9, and the outer wall of the locking sleeve 9 is uniformly distributed with locking tooth keys 10 around the central axis of the locking sleeve 9. The slider 4 is provided with a tooth groove that matches the tooth key, the connecting column 5 is provided with a limiting protrusion, and the locking sleeve 9 is provided with a limiting groove that matches the tooth key. When the height of the lever is adjusted, the locking sleeve 9 is inserted into the slider 4 so that the tooth key is engaged with the tooth groove. Through the cooperation between the tooth groove and the tooth key, and the cooperation between the limiting groove and the limiting protrusion, the lever can be prevented from rotating during use, so that the plug block 6 is separated from the slot 7. When the height of the lever needs to be adjusted, the locking sleeve 9 is pulled out of the slider 4, and the screwing part is turned to adjust the height of the lever.

[0029] A locating pin 11 is provided on the side of the slider 4 close to the lever, and a baffle 12 is rotatably mounted on the locating pin 11. The baffle 12 abuts against the end of the locking sleeve 9 to prevent the locking sleeve 9 from separating from the slider 4 during the use of the lever. When the lever height needs to be adjusted, the baffle 12 can be rotated to pull out the locking sleeve 9.

[0030] The end of the locking sleeve 9 is provided with a hook 13, which is convenient for pulling the locking sleeve 9 out of the slider 4 through the hook 13. Preferably, the lever can be locked by installing the locking sleeve 9 only on one side of the lever to prevent the lever from rotating during use.

[0031] The columns 3 corresponding to the high bar 1 are fixedly mounted on the base 14, and the columns 3 corresponding to the low bar 2 are slidably mounted on the base 14. In the prior art, when the distance between the high bar 1 and the low bar 2 needs to be adjusted, the bolts and brackets for fixing the columns 3 need to be removed, which makes the adjustment troublesome. The design scheme provided by the utility model facilitates the adjustment of the distance between the high bar 1 and the low bar 2.

[0032] A moving seat 15 is provided at the bottom of the column 3 corresponding to the low bar 2, and the moving seat 15 is connected with a screw rod 16. The screw rod 16 is fixedly installed on the base 14. A slide plate 17 is provided at the bottom of the moving seat 15. The slide plate 17 is slidably connected with the base 14. A handle 22 is provided at the end of the screw rod 16. Rotating the handle 22 drives the screw rod 16 to rotate, thereby driving the column 3 corresponding to the low bar 2 to move.

[0033] A marking protrusion 18 is provided on the side wall of the column 3 at a position corresponding to the slot 7, and a marking scale 19 is provided on the side wall of the base 14. By setting the marking protrusion 18, it is convenient for the user to adjust the height of the lever according to the marking protrusion 18, and by using the marking scale 19, it is convenient for the user to adjust the distance between the low bar 2 and the high bar 1.

The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
