Description

4 4 6 6 0 2 C7 D7 V. Creation instructions (/) The joints between the sockets of the socket wrenches in this case have the strength, especially the two types of ratcheting socket wrenches, which are press-type, roller-type and roller-type. The use of twisted teeth and backlash often causes poor operation. Scald disease is caused by the roller sleeve's torque transmission or improper silent trajectory, so that the control of the rolling force is selected from common steel balls. In view of this, the forward and reverse control is not applicable, and the price of the certificate after the test of the creation is expensive; of which, the main structure of the invention in this case is at the connector.

Objective I The internal rotation seat is combined with a roller, a reed, a resistive element composed of a roller and a reed, and the main socket is integrated into an integrated operation. * The operation effect is achieved by the Ministry of Economic Affairs, M-HiA / .; The strength and torque reach the force exerted by the wrench. Convenience refers to those between the handle and the higher torque and efficiency. The hand can be roughly divided into the trouble of the action of the spine to generate the operation, and it is often because the spine has no experience in using it. "Lang Jie's traditional design style of hand-sending torque transmission: hand is insufficient or angle The hand to be eliminated: it is the idling of the eye-column. It is effectively selected by the method of production. It is a clear choice of the person. It is a stable-type sleeve in the state of special force. The main reason is that the tooth strength is not good. With the use of rollers, the disadvantages of using the side-displacement steel balls to resist the fitting slippage are solved. The main expectation lies in the main socket, and the angle and position and the cutting angle are formed by this. It is difficult to smooth the arc-embedding phenomenon. The solution is the ideal effect: the elasticity of the resistance element is arranged between the socket wrenches, and the shift distance is not matched with the * edge. After experience, it has a solid ft. Trend. It is limited by the sleeve body and the internal rotation of the wrench. The paper size is applicable to the standard rate of the households (CNS > A4 size (210X297mm *)).智 ».: 91 谇 ^;: = 丄 printed by the cooperative 446 6 0 2 C7 D7 V. Creation Instructions (Part I) Γ—The second purpose of the invention in this case is the heaving structure of the socket wrench; of which In this case, the side of the stopper that blocks the internal rotation seat is generated by the bias of the moving piece.

The cabin is formed with a suitable section of thread 7 at the end of the rod body. The cover body 8 is sleeved on the rod body of the inner rotation seat 7 with a middle hole 81 and is inserted into the top of the main sleeve seat 2 by the lower ring portion 82. When the lock cover 9 is locked with the screw hole 9 1 and the thread 7 4 of the rod body, a pressure can be formed on the hole 81 in the cover body 8. By the combination of the above-mentioned components, the sleeve body 4 and the roller R 1 and the reed R 2 can be prevented from interlocking with the inner rotary seat 7 and the main socket 2, and the main socket 2 is provided with the inner rotary seat 7 The rotation of diligence, and the effective continuous action with high-strength torque and unlimited operating angle, "Advance, please cooperate with the instructions shown in Figures 3, 4, and 5, when the wrench is intended to operate When rotating in a clockwise direction (that is, in a forward rotation state), the spring fixing member 6 must first be rotated forward so that the torsion spring S can use the stretchability of the spring arm S 1 to push the movable plate 5 to deflect. The end of the movable piece 5 is suitable for blocking the reverse position of the internal rotation seat 7 and the block 7 3 (see the fourth figure, only forward rotation can be implemented). At this time, each roller R1 and reed R2, Will be shifted to the high point of the curved edge 7 1

Central Standard

The internal rotation seat 7 and the main socket 2 are integrated into one body (that is, no relative movement can be generated). Therefore, the main socket 2 will rotate in conjunction with the internal rotation seat 7 to achieve the purpose of torque transmission; It is driven by the reverse rotation of the inner rotary seat 7 to drive the roller r 1 and the reed R 2 away from the curved edge 7

I Cooperative

446602 C7 D7 V. The high point of the creation description (Γ) 1 'disengages the inner rotation seat 7 from the main socket 2. The combination thus loses the function of synchronous rotation, so the wrench will run idly when it is returned to the reverse direction, with or without Features of noise and unlimited displacement. When the wrench is intended to rotate counterclockwise (that is, in a reversed state) to apply force, it is reversed through the spring fixing member 6 so that the torsion spring S can also be extended and pushed by the spring arm s 1_push · movable piece 5 The second is through the 5 end of each moving piece to block the internal rotation seat. 7 block 7 3 in the forward position (as shown in the fifth figure, only reverse rotation ability), at this time each roller R 1 and The reed R .2 is also displaced to the high point of the curved edge 71, so that the inner rotation seat 7 and the main socket 2 are integrated into a reverse force application operation of the wrench, and the reverse displacement of the force application is reversed. Then, because the roller R. 1 breaks away from the high point and no longer squeezes the reed R2, the idling of the wrench assumes a 'sound shape'; using the upper elasticity of the reed R 2 to generate high torque: The inner wall of the sleeve 2 is inconsistent, and the completion force is effective. ^ Additionally, please cooperate with the sixth and seventh figures. If this case is used: when the moving film 5 and 5A of the same size and small, because of the moving film 5, 5A. The blocking effect is not formed synchronously, and it can generate a two-stage displacement positioning effect when the torque of unequal force is transmitted, so that the roller R 1 is not fixed: implementation of linkage control In particular can reduce the formation of concave-bit A chance to wear it, to avoid slipping into the roller R 1 A bit of wear concave (see shown in the seventh). To sum up, the structure of this case uses the deflection method of the moving film to control the rotation of the inner seat to apply force, so that the operation selection will never fail, and the smooth and smooth sliding of the edge will clearly distinguish the operation of the linkage from the linkage_ _ This paper size applies to the Chinese national standard (CNS > Ya 4 threats (210X297 public 5 :. 446602) 5.
