Description of the Invention: [Technical Field of the Invention] The present invention is a screwdriver having a torque controller having the features of the third aspect of the patent application. [Prior Art] A known screwdriver has a handle including a torque controller and a rod mounted in the handle and coaxial with the handle. The rod can be rotated around the handle and torque-fitted via a torque controller. The manner is connected to the handle, wherein each relative rotation between the pole and the handle that achieves at least one characteristic angle represents a switching operation cycle. The advantage of a screwdriver with a torque controller is that it can be used to lock the screw with a constant force. This force ensures the reliability of the screw connection and on the other hand avoids excessive thread loading. The lever is dry to rotate within the handle, and the second::: disassembles the torque controller. When the handle is transmitted to the two-two "over-torque" through the connector, the torque controller will be disengaged, and the same cup will rotate at least one special 5 around the handle! # ^ λ .

The angle between the two adjacent engaging elements according to an advantageous embodiment of the invention, or the number of cams, etc., is an integer ratio of the number of wounds between the flying bowl and the engaging element. In this way, the pole and handle are established. The direct correlation between the number of times of the switch operation cycle is as follows. [Embodiment] 4 The description of the present invention will be made. The first wide view of the first figure to the skirt of the hairpin H) shows the handle of the present invention having a handle 20, and has a root/crossing example. The torque controller is integrated in the hand. A rod 3 inside and coaxial with the handle. The 201244888 torque controller is not part of the present invention, and can be a variety of different types of torque controllers. What is important is that the rod 3〇 is axially rotatable in the handle 2〇, and the torque control of the 4 1 4 acts on the handle 20, and a connection 11” of the device is transmitted to the pole: The compression spring composed of the coil spring =, that is, the wheel-to-dust force of the contraction 88 is engaged, and the connector 78 has the first connector member 8 and the second connector member 84. The first connection The member is coupled to the lever 3q in a non-rotatable manner, and the second connector 84 is coupled to the handle 2A in a non-rotatable manner. For example, the two connectors 80, 84 may have the same number of teeth as the brake teeth 82 1 ' In order to cause the brake teeth to be sprayed to each other when engaged with the connector 。. If the torque transmitted from the handle 2G to the rod % via the connector 78 exceeds a prescribed limit value, the connector 78 is removed by the force of the compression magazine 88. Positioned so that the handle 2〇 can be moved relative to the rod 3. For example, the 'brake teeth 82, 86 slide up and down each other until the 78 is re-engaged. It is also possible to replace the brake teeth 82, 86 with other shaped coupling elements. Made of balls or other similar components The indented component. A switch operating cycle is between the lever 30 and the handle 2: a minimum possible rotation angle. After the connector 78 is moved out of the engaged position, this angle of rotation is necessary until the connector 78 By re-engagement, the present embodiment refers to the angular distance between two adjacent brake teeth of the first connecting element or the angular distance between two adjacent brake teeth of the second connecting element. The screwdriver 10 has a counter that counts the number of switching operation cycles. The counter that counts the number of switching operation cycles can be an active ' 6 - 201244888 component or passive component. In the screwdriver 10 shown in Figs. 1 to 3, an active member composed of the Hall effect sensor 40 and a disk 50 having a plurality of magnetic members 52 are counted. It is also possible to replace the Hall effect sensor 40 with a passive element such as a reed contact. The Hall effector 40 is coupled to the handle 20 in a non-rotatable manner. The disc 50 is connected to the rod in a non-rotatable manner, and in particular, the amount of the rod member 50 is preferably equal to the number of the engaging members, that is, the brake teeth 8 2, 8 6 of the connector 78. Quantity. For example, the connected first connecting element 80 has nine brake teeth 82 and the second connection 84 has nine brake teeth 86. In this case, there are nine magnetic elements 52 in the disc 50 (see Fig. 3). The magnetic element is preferably made of a plastic. The magnetic element 52 can be placed and secured to the disc. The magnetic element 52 and the disc 50 are preferably integrally formed, especially in magnetic plastic. The direction of the Hall effect sensor 40 is axially aligned with the longitudinal axis of the rod 30, and it can be discerned whether or not there is a gap between the magnetic element 52 or the magnetic elements 52 of the two located within its detection range. The Hall sensor 40 is coupled to an electronic calculator that counts the number of times the magnetic element 52 passes through the Hall effect sensor 40. It is also possible to calculate the number of switching operations of the connector 78. The power required by the Hall sensor 40 and the electronic calculator comes from a battery or the like. A display not shown in the figure is provided on the handle 20. The number of switching operation cycles calculated by the calculator can be displayed on the device, and the sensing is 丨. The magnetic is equal to the 78 component of the device also with a magnetic 50 ° is a flat adjacent effect can be used for this effect on the electronic display -7- 201244888. In addition, this display can also display the state of the battery that is powered by the Hall effect sensor, and the set torque when the torque of the torque controller of the screwdriver is changed. When the torque exceeds the specified limit, the display will show the number of switching cycles or the set torque. The display will give a warning or warning indication when the battery is running out. Figures 4 through 9 show a screwdriver 1 〇 ' of another embodiment. The main difference between the screwdriver 10 and the screwdriver shown in Figures i to 3 is the construction of the counter for calculating the number of times the switch operates, and the torque controller is substantially the same. The screwdriver has 1 〇 and has a counter for counting the number of times the switch operates. This counter has a cam disc 70 and a key 6 〇. The cam plate 7 is coupled to the 'sub 30' in a non-rotatable manner, and the electric key 60 is coupled to the hand ^ in a non-rotatable manner. A cam 72 is provided on the cam plate 70. The number of cams 72 is preferably equal to the number of engaging elements of the connector 78. In the present embodiment, ten cams 72 are provided on the cam plate 70 (see Fig. 9, a pair of armatures 75' parallel to the longitudinal axis of the rod 3' is provided between the cam plate 70 and the electric key 6'. Therefore, the electric button 6 can be disposed radially in the cam plate 70 and axially spaced from the cam plate to make the carcass structure more compact. When the cam plate 7 is slid along with the lever 3 and the handle 2: When the relative rotation is rotated, the cam 72 will flip the operating element, and the end of the element 75 facing the cam 72 will be pressed. The electronic calculator connected by a number m will calculate the number of times the key 6 is pressed. The number of times of switch operation of 1〇 and 接78. The display 9设置 set on the handle 20 of the screwdriver can display the number of 201244888 of the switch operation cycle and other important information required by the user.
