And the control motor is positive and reverse by the touch handle of the wrench handle to control the movable clamp body to slide back and forth. The above-mentioned electric adjustable wrench designed to drive the displacement of the movable body by the positive and negative rotation of the motor, although it is convenient to change the size of the jaw, the instantaneous voltage of the movable body is relatively inconsistent with the need to replace the battery after two times. Economical efficiency, and the movable clamp body uses the 冋 voltage mode to start the moment, and it is easy to cause the active central body to move faster. If there is any repair, the finger pinch will occur or the structure of the high-speed Na and the _ component will be damaged. Even, touch The touch switch is set on the side of the handle of the movable wrench, and the other is changed by the positive and negative grip gestures, and the mistake is caused by the mistake. The problem is that the movable body and the docking part are not clamped and unloaded. Wait for the missing. Of course, the above-mentioned lack is also seen in the US Patent No. 4 5 12 2 21, which starts the voltage at a high moment, and the prior art has a lack of space in the flipping space because the motor system that drives the worm is housed in the neck. Highlighting Le, the design of the protrusion is often caused by Qing Lang Jianshi early encounter with the enemy, in fact, the coke 1660049 is ideal.叙'. The above-mentioned silk _ Ou Qian clothing high-power electric shackle is missing, 进步 more improved and approved as the US 6th DM 2 No. 1 patent case. The improved electric adjustable wrench is driven by a low current mode. The driving member of the bump is driven by the driving member to impact the worm to instantaneously rotate to control the displacement of the movable body. The electric adjustable wrench with low starting voltage can improve the battery life, but still exists for the motor. If the design of the department is missing, and the structure of the hard drive is broken, the structure damage caused by the impact, the loss of the life of the worm is shortened, and the overall design of the electric adjustable wrench developed by the industry has not been perfected, and it has been greatly improved. space.

And - touch _, the touch switch and through the sealed cover to perforate, turn, the smoker has to press the touch switch, so that the rotating motor drives the linkage and the secondary wheel body is rotated, and then by The transmission component design makes the main wheel body synchronize _ and the flexible member, which is turned into a parabolic component with large energy, will force the rotation to rotate with low current and high torque, and change the displacement of the movable clamp along the chute. The size of the jaws. [Embodiment] Referring to Figures 1-3, the present invention relates to an electric adjustable wrench that uses low current starting. The electric adjustable wrench mainly includes a body 10, and one end of the body 10 is the other end of the head ii. For the handle 12, the head 11 and the handle 12 are connected with a neck i 3 ; wherein a fixed clip body 111 is extended on one side of the head ii, and a chute 112 is opened in the lateral direction, and the chute 11 2 is provided for The activity of the continuous tooth portion 1131 at the bottom end is lost! 3 can be accommodated in a displaceable manner, and the first slot of the vertical connecting chute ii 2 is provided at the preset portion of the chat 1 2; the first opening of the 'handle 丄 2 and the neck i 3 is recessed-connected The space and the second open space 15 are separated from the first interval 丄4丄 of the communication receiving groove 114 by the protruding partition, and the second interval 14 communicating with the first interval. The third interval 14 3 of the body 1 13 and the fourth interval χ 4 4 of the adjacent second open space 15 are mainly four sections (the number of sections is increased or decreased depending on the actual situation); a worm member 21 ' The volute housed in the accommodating groove 114 is attached to the movable clamp 1306049. The detachable cover 50 is sealed by the screw 70 to seal the first and second open spaces. The extension portion 51 of the wheel body 2 2 and the main wheel body 2 2 of the wheel body 2 2 are stably accommodated in the accommodating groove 4, and the cover body is separately provided with a perforation 5 2 for a set of touch switches to facilitate The hand is worn by a person, and the end face of the switch 40 is touched and designed to be lower than the surface of the body or the cover body to prevent the switch 4 and the object from being touched when placed ( Or ground surface) is pressed against, and the motor 30 to start any operation. • - Electric > also 6 0 'to be directly accommodated in the second open space and electrically connected to the motor ' also has to be shown in the example of the cover body 5 〇 corresponding to the second open space 丄 5 recessed a long shape The tank 60 is opened, and the battery 60 is accommodated therein, and is sealed by a cover sheet 54, that is, assembled into the electric adjustable wrench shown in FIG. The structural object of the operation and preset completion of the electric adjustable wrench of the present invention is further described in detail with the fourth and fifth figures: The electric adjustable wrench of the present invention emphasizes that the movable clamp body 13 13 is displaced in a low current manner, thereby achieving the activity. The opening size between the cool body 113 and the fixed clamp body 111, the user only needs to press the touch switch 4 with the left and right key forms to start the motor 30, and then drive the first and second joints. The linking member C of the members d and e rotates, and then the secondary wheel body 24 rotates, and the main wheel body 2 2 transmits the transmission element 25 between the secondary wheel body 24 and the rotating wheel, and the rotating main wheel body 2 2 The flexible member 23 is forced to be twisted to a preset state, thereby driving the volute member 2 i to rotate and the meshing movable body 113 is laterally slid along the sliding slot 112 to achieve the clamping target size of 1306049. Therefore, the electric adjustable wrench of the present invention is driven by the low current mode to activate the movable clamp body 113, and the problem of starting the movable clamp body 113 in order to overcome the low current cannot provide an instantaneous large voltage. Therefore, the worm gear 21 and the main wheel body 2 are added. The two flexible members 2 3 of the twistable state are designed to twist the flexible member 23 during the rotation of the main wheel body 2, thereby generating accumulated energy to the preset state in the flexible member 23. And the large torque value is released instantaneously, and the displacement of the movable body i3 can be started instantaneously, so that the movable clamp body 113 can quickly adjust the size of the jaws only in a low current mode. The invention realizes the novel idea of the flexible member 23 by using a low current motor with a transmission component and a twistable torsion spring, and the battery 6 can be extended by simultaneously starting the movable clamp body with a low current. The service life makes the battery 60 under the same voltage condition provide more times of the clamping size adjustment function; both, the flexible member 23 assists the low-current electric adjustable wrench to start the movable clamp body with a large torque moment. 13, can avoid the structural damage caused by multiple collisions between the volute 21 of the previous case and the main wheel body 2, in order to extend the service life of the electric adjustable wrench, while using the low current electric adjustable wrench, can also prevent inadvertent In the operation, the finger of the finger is injured. The electric adjustable wrench of the present invention is based on the design of the general adjustable wrench, and is designed to match the first and second open spaces of the body 1 recess. The necessary components for driving the movable clamp body 113 are accommodated therein, so that the electric adjustable wrench of the present invention keeps the general movable wrench easy to grip and exerts force, and does not protrude due to local protrusion during the rotation process. The view, which causes the early collision with the obstruction when the narrow space is turned, the 1306049 is time-consuming missing; the four, because of the starter motor 3, the touch switch 4 is placed in the body 1 of the existing neck 13 and touches The end face is lower than the body or cover design, even if the wrench is laid flat, it will not touch the switch. It can effectively prevent: during the operation, due to the grip of the hand or the start of the motor due to the operation of the workpiece, the motor is changed, causing the work to be lost. The above-mentioned electric adjustable wrench of the present invention smoothly starts the novel idea of the movable clamp body by the low current mode and the flexible member 2 3 , and completely eliminates the structural design loss of the three electric adjustable wrenches mentioned in the prior art, and obtains four advances foreseen in advance. Sexual efficacy can be described as an invention that conforms to novelty and progress. Referring to the sixth embodiment, a second embodiment of the present invention is mainly used for changing the touch switch of the up and down keys into a toggle switch F for left and right switching, and the dialing in the groove. The touch switch F is lower than the surface design of the cover body 50, and can also be switched by the left and right to achieve the motor 30 positive and negative control, thereby changing the size of the jaw. In summary, the present invention utilizes a low current to cooperate with a flexible member to activate the movable movable body of the movable member.
