The end surfaces of the left housing 311 and the right housing 312 are fitted to each other, and together define a fitting space of the motor portion 20. The front part of the assembly space forms an installation cavity, and the rear part forms a battery compartment.
The electromotive part 20 includes: an actuator 21, a circuit board 22, and a power supply 23.
The power supply 23 supplies power to the transmission mechanism 21 and the circuit board 22, and the circuit board 22 controls the operation of the transmission mechanism 21. In the installation mode, the power supply 23 is arranged in the battery compartment at the rear part of the shell 30, and the transmission mechanism 21 is positioned in the installation cavity at the front part of the shell 30.
The transmission mechanism 21 is used for directly driving the batch head 10 to pivot, and comprises: an output shaft 211, a positioning sleeve 212, a shifting fork 213, a cylindrical pin 214 and a motor 215.
Wherein, one end of the output shaft 211 forms the output end of the electric part 20, and the batch head 10 is plugged on the output end. In order to facilitate the detachable insertion of the batch head 10, the output shaft 211 is hollow, the batch head 10 can be inserted into the output shaft 211, and the output shaft 211 is further provided with a magnet 216 capable of attracting the batch head 10, so as to prevent the batch head 10 from being detached from the output shaft 211.

In addition, a bearing 217 is provided between the output shaft 211 and the housing 30 in order to facilitate pivoting of the output shaft 211.
The shift fork 213 has a plurality of prongs 2131 and a shift block 2132 located between any adjacent prongs 2131. The shifting fork 213 is sleeved at the other end of the output shaft 211 through a plurality of fork legs 2131 and shifting blocks 2132, a cylindrical pin 214 is further arranged between any two adjacent fork legs 2131, the positioning sleeve 212 is sleeved on the fork legs 2131 of the shifting fork 213, and any cylindrical pin 214 abuts against the inner side face of the positioning sleeve 212 and the outer side face of the other end of the output shaft 211. Meanwhile, a motor 215 shaft of the motor 215 is in transmission connection with a special-shaped hole formed in the shifting fork 213.
In one embodiment, as shown in fig. 2 and 3, the inner surface of the prong 2131 of the shift fork 213 facing the output shaft 211 is a combination of an arc-shaped surface, a flat surface, and an arc-shaped surface. Two side surfaces of the fork leg 2131 are 2131A. The surface of the block 2132 connected to the prong 2131 on one side is 2132A, the surface connected to the prong 2131 on the other side is 2132B, and the surfaces 2132A and 3132B are inclined toward the center. The outer side surface of the other end of the output shaft 211 abutting against the cylindrical pin 214 is a combination of two flat surfaces 211A, 211B. In order to facilitate the assembly of the position sleeve 212, both sides of the position sleeve 212 are further provided with a stopper protrusion 2121 which is snapped into the housing 30.
Thus, as shown in fig. 4, 5, 6 and 7, when the motor 215 is in an operating state for driving the output torque, the shift fork 213 rotates in the forward or reverse direction, and simultaneously the shift blocks 2132A and 2132B engage with the output shafts 211A and 211B to push the output shaft 211 to rotate; at the same time, its prong 2131 pushes on the cylindrical pin 214, the cylindrical pin 214 now being centered on both sides 211A and 211B. Accordingly, the output can be achieved through the output shaft 211 regardless of whether the shift fork 213 is rotated in the forward or reverse direction.
When the cylindrical pin 214 is clamped between the positioning sleeve 212 and the output shaft 211, the output shaft 211 is locked by the positioning sleeve 212 because the cylindrical pin 214 is clamped, the reverse driving force of the output shaft 211 cannot be transmitted to the shifting fork through the output shaft 211 but is directly transmitted to the positioning sleeve 212, the positioning sleeve 212 has no relative freedom with the shell 30, and therefore the output shaft 211 can be directly driven through the shell 30. At this time, since the palm rest 50 is provided, the free rotation and the operation of the operation method of the electric screwdriver can be facilitated, and the practicability of the operation method of the electric screwdriver and the comfort in use can be improved.
In addition, when the motor 215 drives the shift fork 213 to rotate, as shown in fig. 4 and 5, the surfaces 2132A and 2132B of the shift block 2132 interact with the two planes 211A and 211B of the output shaft 211, so as to drive the output shaft 211 to operate. At this time, as shown in fig. 6 and 7, the cylindrical pin 214 is at the maximum clearance between the output shaft 211 and the positioning sleeve 212 due to the pushing of the side surface 2131A of the fork leg 2131, so that the cylindrical pin 214 can move easily along with the mechanism, and the rotation obstruction and the noise are reduced.
As shown in fig. 8, 9, 10 and 11, when the output shaft 211 is in the active state, i.e., the output shaft 211 is actively rotated, the manual mode is performed. The cylindrical pin 214 will be caught between the output shaft plane 4 and the inner arc surface of the positioning sleeve 212 to form a self-locking.
The circuit board 22 is located between the transmission mechanism 21 and the power supply 23, the power supply 23 is electrically connected with the circuit board 22 through a positive plate, the circuit board 22 is also electrically connected with the shell 30 through a negative plate, and the circuit board 22 is electrically connected with the transmission mechanism 21.
Wherein, circuit board 22 includes that arranged from top to bottom: a control circuit board 221 and a speed regulation circuit board 222. Specifically, the power supply 23 is electrically connected to the control circuit board 221 through the positive electrode tab 24, and the control circuit board 221 is also electrically connected to the case 30 through the negative electrode tab 25, so that a control loop is formed through the case 30.
In order to perform the forward and reverse rotation operation, the control circuit board 221 includes a forward rotation button 223 and a reverse rotation button 224 provided on one side of the housing 30, and the forward rotation button 223 and the reverse rotation button 224 can abut against corresponding contacts on the control circuit board 221. Meanwhile, the speed-adjusting circuit board 222 has a speed-adjusting push button 225 disposed at the other side of the housing 30, so as to facilitate speed-adjusting operation. Correspondingly, the speed-regulating push button 225 can abut against the corresponding contact on the speed-regulating circuit board 222.
The power supply 23 is embodied as a battery, and the positive electrode of the battery is connected to the circuit board 22 via the positive electrode tab 24. The positive plate 24 is accommodated in a pull plate 226, and the positive electrode of the battery can be connected with the positive plate 24 when extending into the pull plate 226, so that the battery cannot be connected when being placed in the reverse direction, and a protection effect is achieved.
