In the figure, 1, arm protection sleeve; 2. a forearm; 3. rotating the centering shaft; 4. a rear arm I; 5. a first connecting head; 6. a second rear arm; 7. a pressure spring; 8. a pawl; 9. knurling a pin; 10. a second connector; 11. a table clamp; 12. the bench clamp is anti-skid; 13. a bench clamp screw; 14. a lock cavity; 15. a tooth socket.

Detailed Description

As shown in figure 1, the wrist support bracket comprises a table clamp 11, a table clamp anti-slip sticker 12 is arranged on the inner bottom surface of the table clamp 11, the table clamp anti-slip sticker 12 and the table clamp 11 are pasted into a whole, and then the table clamp anti-slip sticker 12 is pressed on a table top. The table clamp screw 13 is rotated to be tightly pressed and fixed with the lower table surface of the table top. The table clamp 11 is connected with the second connector 10 through the rotating centering shaft 3; a lifting mechanism is arranged on the second connecting head 10, and a first connecting head 5 of the lifting mechanism is hinged with the front arm 2 through a rotating centering shaft 3. The forearm 2 is fixed with the arm sheath 1 in a contra-aperture way and can rotate. The arm can be used by leaning on the arm sheath 1.

As shown in fig. 2 and 3, the lifting mechanism is composed of a first rear arm 4, a second rear arm 6, a first connecting head 5 and a second connecting head 10. The rear arm I4 is sleeved on the rear arm II 6 and then fixed with the connecting head I5 and the connecting head II 10 into a parallelogram through a knurled pin 9; the front section of the second connector 10 is a one-way ratchet wheel tooth; and a locking mechanism is arranged on the rear arm II 6.

The locking mechanism comprises a pressure spring 7, a pawl 8 and a locking cavity 14, and the pressure spring 7 is embedded into the pawl 8 to form a whole. A locking cavity 14 is arranged at one end of the rear arm II 6, the outer end part of the locking cavity 14 is connected with the connector II 10 through a knurled pin 9, and the inner end part of the locking cavity 14 is connected with the pawl 8 through the knurled pin 9; the pressure spring 7 is pressed against the locking cavity 14; the pawl 8 is attached to a tooth groove 15 of the ratchet wheel tooth through the elasticity of the pressure spring 7.

When the lifting is needed, external force acts on the rear arm II 6 to drive the pawl 8 upwards, so that the pawl 8 is inserted into the tooth groove 15 of the ratchet wheel, and the parallelogram angle formed by the rear arm I4 and the rear arm II 6 is limited, and the height limit is achieved. External force acts on the pawl 8, the pawl 8 is pressed upwards to be separated from the ratchet wheel, so that the first rear arm 4 and the second rear arm 6 descend, and when the external force is separated, the pawl 8 is reset under the action of the pressure spring 7 to be inserted into the tooth groove 15 of the ratchet wheel again to achieve the limiting effect.
