[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1 to 10 As shown, a drive slider 2 is provided on one side surface of the housing 1, a groove 3 is provided inside the drive slider 2, a pin body 4 is provided on the surface of the drive slider 2, a groove 5 is provided on the side surface of the pin body 4 near the drive slider 2, a slope 6 that matches the surface of the groove 5 is provided on one side of the groove 5, and a through hole 7 is provided on the housing 1 on one side of the pin body 4 for the pin body 4 to pass through.

[0032] The pin body 4 has a notch 8 on one side surface near the drive slider 2. The notch 8 passes through the through hole 7 to open the pin body 4.

[0033] A spring groove 9 is provided on the side surface of the pin body 4 away from the drive slider 2, and a pin spring 11 is provided in the spring groove 9.

[0034] One end of the pin spring 11 is sleeved on the connecting pin 10 of the housing 1, and the other end of the pin spring 11 abuts against the inner wall of the spring groove 9.

[0035] Limiting members 12 are provided on both sides along the sliding direction of the drive slider 2, and are limited after the slider moves to a suitable position.

[0036] One end of the drive slider 2 is connected to the slider tension spring 13. One end of the slider tension spring 13 is connected to the drive slider 2, and the other end of the slider tension spring 13 is fixed to the limiting member 12.

[0037] The housing 1 is provided with a guide pin 14 that matches the sliding direction of the drive slider 2, which guides the movement of the drive slider 2 and prevents it from deviating.

[0038] A bent plate 15 is provided on one side of the housing 1. A connecting pin 10 is fixed to the bent plate 15.

[0039] A protective cover 16 is provided on the upper side of one side of the pin body 4 to protect the pin body and the pin spring 11.

[0040] The lower end of the protective cover 16 is provided with a locking foot 17, and the housing 1 is provided with a locking hole 18 that cooperates with the locking foot 17. The protective cover is locked in place by the cooperation of the locking foot 17 and the locking hole 18.

[0041] In use, the housing 1 is secured within the height adjustment assembly. When opening is required, external force is applied to the drive slider 2, causing the slider spring 13 to stretch. With the cooperation of the inclined groove 3 within the drive slider 2 and the inclined surface 6 within the groove of the pin body, the pin body 4 drives the slider 2 to slide horizontally and move backward. The notch 8 of the pin body 4 enters the through hole 7 of the housing 1, and the pin spring 11 is compressed and shortened until the drive slider 2 stops moving when it abuts against the limiting member 12 on one side, thus completing the opening of the pin body 4 and obtaining the desired result. Figures 13 to 14In the open state, the height is adjusted by the action of other components of the height adjustment assembly. After adjusting to the appropriate height and removing the external force, the slider 2 and the pin body 4 are driven to reset and re-lock under the action of the pin spring 11 and the slider tension spring 13, as shown. Figures 11 to 12 As shown.
