Please read the first; after the 2-way idling, and then press the operation, moderately increase the ratchet teeth = In the case of the same volume, every time one of the four ratchet gears spanning one to four is Yingshisan 30 teeth, the free space is controlled in a limited space of 30 degrees in the opposite direction, and the square is rotated 12 degrees, at the same), and its Then the positive control operation can span two teeth (the more the number of teeth at 24 degrees, the more beneficial it is in the limited range: Cheng's. Therefore, the more the number of teeth of ratchet teeth 1 4 is, the more Many cases ::: operation ;, see Figure 3C, the degree of articulation of the moving block 1 2 A will be two: the smaller the tooth depth is, the better the eye is and the palm body 10 is biased toward the locking block i 2丄 In this way, the control block 1 2 A slips away from the coupling during the detent operation. Another: Side time: it will be more likely to cause the engine J. Therefore, a single detent block is used as M242334. V. Creation Instructions (3) -------- ---- ~~ .... I. Strict force = dynamic transmission, which is insufficient to increase the weight of the ratchet teeth.

Creation Instructions (4) ------ ~ —____ Because it is still a problem of using a single actuating block, especially in its The ratchet teeth 3 4 special movements will still produce insufficient torque and low degree of detent meshing, which will cause detents. When the number is large, the situation of slippage will be greatly reduced. The main purpose of this creation is to provide—the control body is provided with a double-symmetrical ratchet gear on the control body and a ratchet tooth meshing latch on the ratchet body, and a symmetrical latching element to rotate clockwise or counterclockwise, respectively. At that time, the control body of Fuzhong Yitian was linked by the handles to engage the two sides of the ratchet teeth: the symmetrical actuating elements of the group would be divided into symmetrical driving forces; by this, == both sides of the ratchet teeth At the same time, there is a gap between the bodies, resulting in a bias; the control body is in a state of being locked with the ratchet, and the two sides are symmetrical = the problem, which can ensure the stability of the resistance = 70 pieces of each The average load reverses the time load, that is, each single trigger in this creation can effectively reduce the negative -half 'of the trigger. Therefore, it can greatly increase the rotation operation. The load is only the other part of this creation. The purpose is to mention: = 2. When the ratchet wheel of the control body is clockwise f bi-symmetrical, the ratchet wheel is installed with one of the symmetrical detent elements 80 or counterclockwise, because it is on the side, it can ensure stable engagement. Based on the ratchet teeth, this creation can greatly increase the state of ratcheting two movements, on the premise of this; the curtain movement state, which can be in the opposite direction J f can still ensure a stable mouth ^ and improve the forward positive operation Time-, increase its rotatable angle for use.仃 程 ， 俾 利 Within a limited space [Embodiment]
