The hand support board can be moved horizontally through the slider, and the angle or direction of the hand support board can be rotated relative to the ball joint bearing to finally reach a more comfortable position. In addition, during the operation of the slit lamp, the user can also exert force on the arm to change the horizontal position and angle of the hand support board, which is highly flexible to use;

[0013] 2. Setting the limiter can pre-define the angle of the hand support board to avoid excessive force causing the angle of the hand support board to exceed the user's comfortable range;

[0014] 3. The arc-shaped depression on the palm rest can better support the user's arm to prevent the arm from slipping, and the soft pad can prevent excessive squeezing of the arm when exerting force. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0020] Example:

[0021] like Figure 1-Figure 2As shown, a slit lamp hand support frame includes a hand support plate 10, a support plate 20, a telescopic rod and a base 40. The telescopic rod is vertically arranged on the top of the base 40, and includes a movable section 31 and a fixed section 32 sleeved on the outside of the movable section 31. The fixed section 32 is fixedly connected to the base 40, and the end of the movable section 31 is connected to the support plate 20. A second threaded hole is provided on the top side wall of the fixed section 32, and a bolt 33 serving as a locking member is provided at the second threaded hole; a slide groove 21 is opened on the support plate 20, and a slider 22 matching the slide groove 21 is provided in the slide groove 21, and a ball joint bearing 50 connected to the slider 22 is provided in the middle of the bottom of the hand support plate 10.

[0022] The working principle of the above technical solution is as follows:

[0023] When in use, the hand support can be installed on the side of the existing slit lamp through the base 40, and the height of the telescopic rod can be adjusted after loosening the bolt 33. After adjustment, the bolt 33 is tightened again, and the end of the bolt 33 is pressed against the movable section 31 to achieve fixation. The user can put his arm on the hand support board 10, and the arm can exert force when squeezing the hand support board 10. According to the user's comfortable position, the slider 22 can be pushed horizontally in the slide groove 21, and the angle or direction of the hand support board 10 can be rotated around the ball joint bearing 50 to achieve a more comfortable position.

[0024] In another embodiment, if Figure 1-2 As shown, a limit piece is provided on the support plate 20 corresponding to both sides of the slide groove 21, and the limit piece is within the bottom range of the hand support plate 10; the limit piece includes a threaded rod 61 and a limit head 62, and the top of the limit head 62 can be an arc-shaped protrusion, and a first threaded hole 23 matching the threaded rod 61 is provided on the support plate 20, and the threaded rod 61 is penetrated through the first threaded hole 23, and the limit head 62 is arranged at one end of the top of the threaded rod 61, and a connecting groove matching the end of the threaded rod 61 is opened at the bottom of the limit head 62, and the limit head 62 is sleeved with the end of the limit head 62 through the connecting groove.

[0025] The threaded rods 61 on both sides can be rotated respectively to adjust the height of the limit head 62. When the hand support board 10 contacts the limit head 62 after rotating an angle, the limit head 62 limits the angle of the hand support board 10. The setting of the limit piece can pre-limit the angle of the hand support board 10 to avoid excessive force causing the angle of the hand support board 10 to exceed the comfortable range of the user.

[0026] In another embodiment, if Figure 1 As shown, an arc-shaped depression 11 is provided on the top of the hand support plate 10, and a soft pad 12 is provided on the upper surface of the arc-shaped depression 11, and a cotton pad can be selected.

[0027] The arc-shaped depression 11 on the arm support plate 10 can better support the user's arm to prevent the arm from slipping out, and the soft pad 12 can prevent the arm from being excessively squeezed when exerting force.

[0028] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
