The advantage is that when the card block is not easy to be damaged, it has the advantage of being convenient and convenient to use. 、% ， Extended structure strengthening, [Prior technology] The type of ratchet wrench depends on the use situation and the eight different configurations, one of which is different according to the parts in the second picture ...) = (soil 2) When the position is equipped with a drive The head body (11 3) is provided with a turning knob (14,), and the driving head is set in the driving head (13) = the moving knob (14) can have an elastic post () on the side of the rod (1 5), Move, so that the card block (16) on the turn 5) side can be moved by 2 = turn lever " here-come, when the user = X ratchet (" ", such as (") drives the setting i = To make the lever rotate, the lever (1 7) under the technique * ^ ^ j) can be connected to the base and I ... 7) The sleeve can be turned to open and close the bolt. The knot 4 has the following: If the user uses it, if it is used for a long time, 1) dH1; 6) and the internal ratchet teeth (1 3 teeth) of the driving head (1 3), phase f = ί resistance, the palm groove of the card block (16) and The ratchet and jamming can only be absorbed by a single point. Relative to the block (i 6) p. 5 M258827 Mouth, creation instructions (2) Twisting the internal ratchet teeth (1 β finely reduced 'and bearing insufficient torque, resulting in insufficient use Application status' if in use In the case of cracking, the life span of the aforementioned single-point clamping force structure is greatly reduced due to the eccentricity of the internal ratchet (1 3 1 5). The creators have considered the shortcomings of the problem, and worked to completely solve the problem. [New content] This creation "The high-torsion type is evenly stressed, and the structure is to meet the requirements of the main body. The internal space of the main body is accommodated. The outer periphery of the drive head is on the opposite side. It is small, and the block can be mutually stable with the internal ratchet teeth 1) when it is on both sides, and it is shaped when it is hard to pull if it bears less stress. The resulting application is caused by the card block (the conventional ratchet wrench is used to test the stability of the force of the ratchet device. In the special space, the inner edge of the central block of the internal ratchet teeth is driven to achieve a philophilic structure. "High torque to As follows, the empty moving head is placed, and the pivots are placed at the position, and this block is symmetrically engaged; it can withstand or be the same 'only the point structure can be restrained, but) 16), the structure is irrelevant, and the final problem. The main internal ratchet V. Structure The driving head is provided with a card with a ratcheting mechanism on the outer periphery of the card. The torque is largely due to the small contact surface. It is suitable for low stress, but it may be improved due to the stress concentration. (16) The bearing is easy to cause the rotating rod (1 to generate stress concentration, so that the method can overcome the torque instability and successfully create this creative capacity: to provide a request; to achieve internal ratchet teeth, and a joint at the bottom of the body, such angles Triangular chamfered block, the edge of the block is slightly more toothed than the inner diameter of the internal ratchet, which is oscillating
