The left side is a boss cylinder 411 having a large outer diameter, and the right side is a ratchet cylinder 412 having a small outer diameter; the ratchet circle is The cartridge 412 is inserted into the first palm ratchet sleeve 11 from left to right, and the boss cylinder 411 is stuck outside the first palm ratchet sleeve 11, facing the right at the right end of the boss cylinder 411, along the ratchet circle The outer surface of the cylinder 412 is provided with two first fixed teeth 413 corresponding to the position of the first fixed tooth slot 111. When the ratchet cylinder 412 is inserted into the first palm ratchet sleeve 11, the first fixed tooth 413 The inner diameter of the boss cylinder 411 can be just inserted into the first fixed tooth slot 111. The inner diameter of the boss cylinder 411 is larger than the inner diameter of the ratchet cylinder 412. Therefore, a support platform 414 is formed on the top surface of the ratchet cylinder 412 and the boss cylinder 411. A right-handed ratchet is provided on the right end surface of the ratchet cylinder 412. The finger ratchet 42 has a cylindrical shape extending in the left-right direction, and conforms to the outer diameter and the inner diameter of the ratchet cylinder 412, and a left-handed ratchet is provided on the left end surface of the finger ratchet 42. The ratchet teeth on the ratchet cylinder 412 and the ratchet teeth on the finger ratchet 42 can be engaged to form a ratchet mechanism that can only rotate in one direction after engagement, and the right end of the cylindrical outer surface of the finger ratchet 42 is provided with three equidistant distributions along the circumference. The convex card 421, the finger ratchet 42 is inserted into the finger ratchet sleeve 22 from the right side, and the convex card 421 is located in the positioning card slot 221, so that the finger ratchet 42 can only reciprocate axially along the positioning slot 221; the connecting shaft 43 includes The left end is a cylinder structure, a large diameter ring, and an unlocking button 431 adapted to the inner ring of the button sleeve 21, the right end is a cylindrical structure, the circumference diameter is small, and the ratchet cylinder 412 and the finger ratchet 42 inner diameter are adapted. The horizontal axis 432, the right end face of the finger ratchet 42 is closed, and only a through hole for the screw to pass through is provided at the center of the circle. The connecting shaft 43 is inserted through the spring 45 from the left side of the button sleeve 21, the button sleeve 21, and the first After the palm ratchet 41 (placed in the first palm ratchet sleeve 11), the horizontal axis 432 of the right end of the connecting shaft 43 is inserted into the finger ratchet 42 (placed in the finger ratchet sleeve 22), and the screw passes through the finger ratchet from right to left. 42 the hole of the right end surface is screwed on the right end surface of the horizontal axis 432, The connecting shaft 43 and the finger ratchet 42 are fixedly coupled together (as shown in FIG. 3 and FIG. 4); the spring 45 is disposed outside the horizontal axis 432 and is disposed in a compressed state between the right end surface of the unlocking button 431 and the supporting platform 414. Thus, the first palm ratchet 41 and the finger ratchet 42 are meshed together without an external force. Since the connecting shaft 43 is fixedly coupled to the finger ratchet 42, pressing the connecting shaft 43 to the right causes the finger ratchet 42 to move to the right, so that the first palm ratchet 41 and the finger ratchet 42 are disengaged.
具体地,第一手掌棘轮41通过第一固定齿413卡在第一固定齿卡槽111内,使第一手掌棘轮41和手掌部分1始终保持不可转动的连接,手指棘轮42通过凸卡421卡在定位卡槽221内,使手指部分2和手指棘轮42始终保持不可转动的连接,当人手向内握的时候,手指棘轮42左端面和第一手掌棘轮41右端面上啮合的棘齿使手指部分2以向内握的方向转动,而想要张开手指时,手指棘轮42左端面和第一手掌棘轮41右端面上啮合的棘齿卡住不能转动;连接轴43与手指棘轮42固定连接,向右按开锁按键431会带动手指棘轮42向右移动,进而使手指棘轮42左端面和第一手掌棘轮41右端面上的棘齿分离不再啮合,这时人手可张开;松开开锁按键431,弹簧45恢复弹性形变会以支撑平台414为基础,将连接轴43向左顶,使手指棘轮42左端面和第一手掌棘轮41右端面上的棘齿重新啮合。Specifically, the first palm ratchet 41 is caught in the first fixed tooth slot 111 by the first fixed tooth 413, so that the first palm ratchet 41 and the palm portion 1 are always kept in a non-rotatable connection, and the finger ratchet 42 is passed through the convex card 421 card. In the positioning card slot 221, the finger portion 2 and the finger ratchet 42 are always kept in a non-rotatable connection. When the hand is gripped inward, the ratchet of the left end face of the finger ratchet 42 and the right end face of the first palm ratchet 41 makes the finger The portion 2 is rotated in the direction of the inward grip, and when the finger is desired to be opened, the ratchet teeth engaged with the left end surface of the finger ratchet 42 and the right end surface of the first palm ratchet 41 cannot be rotated; the connecting shaft 43 is fixedly connected with the finger ratchet 42 Pressing the unlock button 431 to the right will move the finger ratchet 42 to the right, so that the left end face of the finger ratchet 42 and the ratchet on the right end face of the first palm ratchet 41 are no longer engaged, and the hand can be opened; Pressing the button 431, the spring 45 resumes the elastic deformation.
