Description

Ratchet wrench tool with reversible hands and electric operation mode

technical field

The utility model relates to a wrench tool, in particular to a ratchet wrench tool in which the user can choose to drive the tool head in a manual or electric operation mode for disassembly and assembly operations, and then achieve a switchable hand and electric operation mode for easy conversion operation.

Background technique

Please refer to Fig. 1, the ratchet wrench tool of existing power, it is that a ratchet handle 20 is fixedly set at handle 10 one end, and the front end of ratchet handle 20 then is a ratchet seat 21, has a drive by power source in the handle 10. The motor is used to drive the components in the ratchet seat 21 to move; please refer to Fig. 2 , there is a sectional groove 210 in the middle of the ratchet seat 21, so that the left and right clamping frames 211, 212 are formed on both sides, and the left clamping frame 211 is provided with a small-diameter perforation 213, the right clip frame 212 is provided with a large-diameter perforation 214, one end of a rotating shaft 22 is connected to the motor, and the other end has an eccentric shaft 221 to drive a driving block 222 to rotate, and a pulling member 23 is provided with a socket 231 and the inner The ring ratchet 232 uses the socket 231 to cover the driving block 222, so that when the rotating shaft 22 is rotating, the eccentric shaft 221 can drive the trigger member 23 to rotate and swing back and forth. A ratchet head 24 has an actuating column 241 at one end, The other end has a direction button 242, and the direction button 242 can control the catch 243 in the ratchet head 24, to control the braking direction of the inner ring ratchet 232 of the catch 243 and the puller 23, and select For forward rotation or reverse rotation, the ratchet head 24 has a spring washer 25 sleeved on the end of the direction button 242, which is pierced through the small-diameter perforation 213 of the left clamp frame 211, and a gasket 26 is sleeved on the end of the actuating column 241. , with a C buckle 27 fastened in the ring side groove 215 of the large-diameter perforation hole 214 of the right clamping frame to limit the position, and complete the assembly and positioning; please refer to Figure 3, when the rotating shaft 22 rotates, the pulling member 23 is turned forward When rotating and swinging, the actuating column 241 of the ratchet head 24 can be driven to rotate due to the engagement of the trigger member 243 with the inner ring ratchet 232, but when the trigger member 23 swings back in the opposite direction, the inner ring ratchet 232 is Push the stopper 243 to shrink inwardly, and do reverse idling stroke, and when the benefit is rotated forward again, it will drive the actuating column 241 of the ratchet head 24 to rotate. It is noteworthy that when the puller 23. When swinging back in reverse for idling travel, the ratchet head 24 must be fixed. Otherwise, it will not be able to loosen or tighten the workpiece with the reverse swing of the puller 23. However, the ratchet head 24 must be fixed. The way is to rely on the elastic force of the spring washer 25 to support the friction force generated by the inner wall surface 216 of the left clamping frame 211 and the C buckle 27, so that the ratchet head 24 is fixed, but when the puller 23 is positively When the swing of the ratchet head 24 works, the trigger member 23 is more likely to overcome the frictional force because it is locked with the trigger member 243, and then drives the actuating column 241 of the ratchet head 24 to rotate and perform work. In any case, the frictional force is Necessary, but can not be too large to affect the work of the puller 23 when it swings forward, so moderate friction is very important.

However, the above-mentioned power wrench tool still has the following disadvantages in terms of transmission or usage:

The rotating shaft 22 driven by the motor uses the eccentric shaft 221 to drive the puller 23 to reciprocate forward and reverse swings, and then through the ratchet locking effect of the locking member 243 and the inner ring ratchet 232, the locking is used to drive the contact with the ratchet. The idling reset alternately drives the ratchet head 24 to actuate, and the above-mentioned idling reset action causes power loss of the motor.

The motor that drives the rotating shaft 22 to rotate is very easy to control to make forward and reverse rotation changes, so that the ratchet head 24 can switch the steering action, but the design of the power wrench tool is based on the direction knob 242 and the catch 243 Cooperating with the ratchet locking effect of the inner ring ratchet 232, the switching steering action is achieved, which instead causes complexity in the switching control.

The power wrench tool is designed to be driven by a motor only, but when the power is insufficient to make the motor rotate, the power wrench tool will not work at all, and it is only applicable to the power operation mode , so the use efficiency is still insufficient.

In view of this, the inventor of the utility model has been engaged in research and development and production experience in related industries for many years, and has conducted in-depth research on the problems currently faced. After long-term hard research and trial production, he has finally created a convertible hand, electric The ratchet wrench tool of the operation mode is to greatly improve the existing disadvantages, which is the design purpose of the present utility model.
