Background
Electric screwdriver is as an instrument commonly used in life, it is very extensive to use, the installation of screw has been made things convenient for, the efficiency of installing and removing the screw has been improved, but, to ordinary electric screwdriver, the user often can't the direct rotational speed of experiencing the motor, cause the motor too fast because of the rotational speed, thereby lead to the problem that the screw thread skidded, electric screwdriver is felt to current body, because the sensor that the price is expensive has been used, the price/performance ratio is low, though powerful, but not be applicable to the inside little maintenance of family, in addition, current electric screwdriver has few hands-off protect function, in case in use takes off the hand, electric screwdriver in work collides with other article, cause the unnecessary loss easily.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem among the prior art, provide the electric screwdriver of feedback is felt to a body.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a body feels electric screwdriver of feedback, it is including criticizing head, sleeve, motor, slip varistor structure, button, resilience structure, baffle and power module, criticize head, sleeve, motor, install the front portion at casing and bearing structure, the lateral surface at casing and bearing structure is installed to the button, slip varistor structure, resilience structure, baffle are installed at casing and bearing structure's medial surface, power module's wire links to each other with power module's power after establishing ties motor, slip varistor structure, installs the inside at casing and bearing structure.
Further, the batch head and the sleeve are magnetic, and the axial position of the batch head is determined by the sleeve.
Further, the cross section of the matching part of the batch head and the sleeve is polygonal, and the circumferential position of the batch head is determined by the sleeve.
Furthermore, the sleeve is matched with the motor, the position of the sleeve is determined by the extending shaft of the motor, and the motor is matched with a lead of the power supply module and is connected into a circuit.
Furthermore, the positions of the sliding rheostat structure, the button and the rebound structure are constrained by the baffle, the shell and the supporting structure, the button is matched with the rebound structure, the rebound structure is matched with the baffle, and the sliding end of the sliding rheostat structure is matched with the button and is connected into a circuit.
Further, the maximum resistance end of the sliding variable resistance structure access circuit is coated with a circle of insulating paint.
Further, the power supply of the power supply module is a rechargeable lithium battery.
Further, the motor has the functions of gear adjustment and forward and reverse rotation.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a power module supplies power, utilizes one set of simple mechanical-electrical conversion structure of constituteing by slip varistor structure and resilience structure, realizes perception and regulation to electric screwdriver motor speed, when the installation of messenger's screw is dismantled in-process and is needed high rotational speed, press the button resilience structure just can real-time improvement resilience force, when needing low rotational speed, loosen the button resilience structure just can real-time reduction resilience force, the convenience of customers perception.
The resistance is changed by sliding the rheostat structure, so that the change of the rotating speed of the motor is realized by changing the power, the rotating speed can be increased in real time by pressing the button screwdriver when the high rotating speed is needed in the process of mounting and dismounting the screw, and the rotating speed can be reduced in real time by loosening the button screwdriver when the low rotating speed is needed.
The mode of coating insulating paint at the maximum resistance end of the sliding rheostat structure access circuit realizes that the rebound structure automatically bounces when the user does not need or takes off the hand, the sliding end of the sliding rheostat structure slides to the insulating layer, and the motor automatically closes, so that the screwdriver is safer when in use.
Drawings
1. Fig. 1 is a schematic structural view of an electric screwdriver with somatosensory feedback according to the present invention, 1-screwdriver head, 2-sleeve, 9-shell and supporting structure.
2. Fig. 2 is a schematic diagram of the circuit connection of the electric screwdriver with somatosensory feedback, which is shown in the figure, and comprises a 3-motor, a 4-sliding rheostat structure, a 5-button, a 6-resilience structure, a 7-baffle and an 8-power supply module.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention. The embodiment is described with reference to fig. 1-2, and the electric screwdriver with somatosensory feedback comprises a screwdriver head (1), a sleeve (2), a motor (3), a sliding rheostat (4), a button (5), a spring (6), a baffle (7) and a lithium battery (8), wherein the screwdriver head (1), the sleeve (2) and the motor (3) are mounted at the front part of a shell and a supporting structure (9), the button (5) is mounted on the outer side surface of the shell and the supporting structure (9), the sliding rheostat (4), the spring (6) and the baffle (7) are mounted on the inner side surface of the shell and the supporting structure (9), and a wire of the lithium battery (8) is connected with a power supply of the lithium battery (8) after the motor (3) and the sliding rheostat (4) are connected in series and then mounted inside the shell and the supporting structure (9).
