[0030] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0031] According to an embodiment of the utility model, an electric tool is provided. Figures 1 to 8 , comprising: a tool body 1, on which a tool head 11 is mounted; a handle 2, which comprises a connecting component 21 sleeved on the tool body 1 and a holding component 22 connected to the connecting component 21, and the connecting component 21 is rotatably arranged around the axis of the tool body 1; a limiting component 3, which is respectively connected to the tool body 1 and the connecting component 21 to limit the rotation of the handle 2.
[0032] By providing the limiting component 3, the handle 2 is stopped and positioned, so that the handle 2 and the tool body 1 remain relatively fixed, thereby avoiding relative sliding when the electric tool is in operation.
[0033] Through the above-mentioned setting, the handle 2 can be rotated relative to the tool body 1 and the tool head 11, so that the direction of the handle 2 can be adjusted. Different rotation angles can be selected according to the user's usage requirements to improve the comfort and convenience of operation, improve the user's usage experience, and solve the technical problem in the related technology that the handle of the electric tool cannot change direction.
[0034] As described in the background technology, medical equipment in the prior art usually installs an electric tool on a robotic arm, and positions the electric tool through the robotic arm. After the electric tool reaches the specified position, the doctor holds the handle 2 to manipulate the electric tool for treatment. At this time, the tool body 1 is fixedly connected to the robotic arm, and the electric tool has been positioned. If the structure of the fixed handle is maintained, the doctor may hold the handle 2 in an awkward posture during the operation, affecting the doctor's user experience and work efficiency.
[0035] When the electric tool of this embodiment is applied to medical equipment, the doctor can rotate the handle 2 according to actual needs to change the direction of the handle 2 and perform surgical operations in a comfortable posture, thereby improving the doctor's operating comfort and the convenience of using the electric tool.
[0036] In the electric tool of this embodiment, see Figure 3The tool body 1 contains a driving component 4 connected to the tool head 11, and a starting component 5 for controlling the driving component 4 is installed on the handle 2. The starting component 5 is connected to the handle 2; the handle 2 has an initial position and a rotation position connected to the tool body 1. When the handle 2 is in the initial position and the rotation position, the starting component 5 can control the opening and closing of the driving component 4. Through the above arrangement, the starting component 5 rotates with the handle 2. The electric tool in this embodiment can be opened and closed freely without being affected by the rotation angle. Not only in the initial position, when the handle 2 is in the rotation position, the driving component 4 can be controlled to open or close by the starting component 5 to complete the surgical operation, thereby improving the convenience of operation.
[0037] Preferably, the driving component 4 is a motor, and when the driving component 4 is turned on, the tool head 11 can be controlled to rotate relative to the tool body 1 .
[0038] It can be understood that the tool head 11 in this embodiment includes but is not limited to tools such as an electric drill and a screwdriver.
[0039] In the electric tool of this embodiment, see Figure 3-4 The tool body 1 includes a sensing part 41, and the sensing part 41 is connected to the driving part 4 by signal; the starting part 5 includes a starting part 51 corresponding to the sensing part 41, and when the starting part 51 is connected to the sensing part 41, the driving part 4 is turned on; when the handle 2 is in the initial position and the rotation position, the starting part 51 and the sensing part 41 can be connected. Through the above arrangement, when the handle 2 is in the initial position or the rotation position, the starting part 51 and the sensing part 41 can be connected, and the starting part 51 is controlled to be connected to the sensing part 41, so that the sensing part 41 is triggered, thereby obtaining the start signal of the driving part 4, and the driving part 4 drives the tool head 11 to work.
[0040] In the electric tool of this embodiment, see Figure 4 The starting part 51 includes an induction magnet 511. When the induction magnet 511 is close to the induction part 41, the starting part 51 is connected to the induction part 41, and the driving component 4 can be turned on.
[0041] Preferably, the sensing part 41 is a Hall sensor. When the handle 2 is in the initial position or the rotation position, the sensing magnet 511 approaches the sensing part 41, thereby triggering the sensing part 41. There is no need for the starting part 51 to directly contact the sensing part 41, thereby avoiding interference from structures such as cables during the rotation of the handle 2.
[0042] It is understandable that the sensing portion 41 of this embodiment may also be other types of non-contact sensors in addition to the Hall sensor.
[0043] Specifically, the electric tool includes a mounting sleeve inserted into the tool body 1, a sensing part 41 is installed between the mounting sleeve and the inner wall of the tool body 1, the sensing part 41 and the starting part 51 are separated by the side wall of the tool body 1, the sensing part 41 and the driving component 4 are connected through a circuit, and the mounting sleeve is clamped to the inner wall of the tool body 1 through a positioning boss to prevent relative rotation between the mounting sleeve and the tool body 1, thereby ensuring that the sensing part 41 and the starting part 51 can correspond accurately.
[0044] In the electric tool of this embodiment, see Figure 6 The start component 5 includes: a lifting component 52, a start part 51 is installed at one end of the lifting component 52 close to the tool body 1, and the lifting component 52 is movably arranged along the radial direction of the tool body 1 to connect or disconnect the sensing part 41 with the start part 51; a start button 53, the start button 53 is installed on the handle 2, and the start button 53 is used to control the movement of the lifting component 52. Through the above arrangement, the lifting component 52 is movably arranged, and by controlling the start button 53, the lifting component 52 is moved close to the tool body 1, thereby triggering the sensing part 41, and the lifting component 52 is controlled to be away from the tool body 1, thereby disconnecting the start part 51 from the sensing part 41, and at the same time, it is prevented that the start part 51 collides with the tool body 1 during the rotation process.
[0045] Specifically, the induction magnet 511 is embedded in the starting portion 51 , and the starting portion 51 is protrudingly disposed at the end of the lifting component 52 to improve the triggering effect.
[0046] In the electric tool of this embodiment, see Figure 6-7 The start component 5 includes a connecting rod 54, the extension direction of which is parallel to the axis of the tool body 1, one end of which is connected to the start button 53, and the other end of which is provided with a connecting pin 55; the lifting component 52 includes a lifting chute 521, which is slidably connected to the connecting pin 55, and the lifting chute 521 is tilted. When the start button 53 is pressed, the connecting rod 54 drives the connecting pin 55 to slide in the lifting chute 521, so that the lifting component 52 is close to the tool body 1. Through the above arrangement, the transmission direction of the pressure is changed, and the start button 53 can be set at the "trigger" of the electric tool. By pressing the start button 53, the lifting component 52 can be close to the tool body 1, thereby turning on the driving component 4, which improves the convenience and comfort of using the electric tool.
[0047] Specifically, along the direction away from the start button 53 , the lifting slot 521 gradually approaches the connecting rod 54 .
[0048] In the electric tool of this embodiment, see Figure 3The handle 2 includes a mounting groove 23, the mounting groove 23 is slidably connected to at least a part of the start button 53, and the start component 5 includes a first elastic member 56, one end of the first elastic member 56 abuts against the start button 53, and the other end of the first elastic member 56 abuts against the bottom surface of the mounting groove 23. Through the above arrangement, when the start button 53 is no longer pressed by the human hand, the first elastic member 56 in the compressed state pushes the start button 53 to automatically reset under the action of elastic force.
[0049] Specifically, the start button 53 is provided with a cavity for accommodating at least part of the first elastic member 56 . The first elastic member 56 is passed through the connecting rod 54 . The connecting rod 54 passes through the mounting groove 23 and the cavity for accommodating the first elastic member 56 and is fixedly connected to the start button 53 .
[0050] Specifically, see Figure 6 A stopper is provided at the end of the connecting rod 54, and a connecting pin 55 is provided on the stopper. The outer diameter of the stopper is larger than the outer diameter of the connecting rod 54. On the one hand, the structural strength of the connecting rod 54 can be increased. On the other hand, the stopper can be stopped by the outer wall of the mounting groove 23 to prevent the connecting pin 55 from being separated from the lifting slide groove 521.
[0051] In the electric tool of this embodiment, see Figure 3 , 5 The tool body 1 includes a limiting hole 12; the limiting component 3 includes a limiting portion 31, which is movably connected to the connecting component 21, and the limiting portion 31 is embedded in the limiting hole 12 to limit the rotation of the handle 2. Through the above arrangement, when the limiting portion 31 is embedded in the limiting hole 12, the handle 2 cannot rotate. When the limiting portion 31 is moved to leave the limiting hole 12, the handle 2 can rotate.
[0052] In the electric tool of this embodiment, see Figure 3 The limiting component 3 includes: a limiting slide groove 32, which is provided on the connecting component 21, and the limiting slide groove 32 is slidably connected to the limiting portion 31; a second elastic member 33, one end of the second elastic member 33 is connected to the limiting portion 31, and the other end of the second elastic member 33 is connected to the limiting slide groove 32, and the extension direction of the second elastic member 33 is parallel to the extension direction of the tool body 1; a limiting button 34, and the limiting button 34 is connected to the limiting portion 31 to control the movement of the limiting portion 31.
[0053] Through the above arrangement, when the limit button 34 is pushed along the extension direction of the tool body 1 to make the limit part 31 leave the limit hole 12, the handle 2 is out of the limit state and can rotate freely until the handle 2 rotates to the rotation position. When the human hand leaves the limit button 34, due to the elastic force of the second elastic member 33, the second elastic member 33 pushes the limit part 31 to automatically reset and snap into the limit hole 12.
[0054] Preferably, the start button 53 is located at the "trigger" and the limit button 34 is located on the opposite side of the start button 53. When the doctor holds the handle 2, the limit button 34 can be touched by the index finger to achieve one-handed operation. Of course, the limit button 34 can also be adjusted to a position on the handle 2, the side of the connecting component 21, etc. according to actual needs.
[0055] In the electric tool of this embodiment, see Figure 8 The limiting holes 12 include a plurality of limiting holes 12, which are distributed in a circular array around the axis of the tool body 1. Through the above arrangement, the handle 2 can have a plurality of rotation positions, and the positioning and stopping of the plurality of rotation positions can be achieved through the plurality of limiting holes 12.
[0056] Correspondingly, a plurality of sensing parts 41 are correspondingly provided so that the driving component 4 can be controlled to start when the electric tool is at different rotation positions.
[0057] Preferably, the limiting holes 12 and the sensing parts 41 each include four, the four limiting holes 12 are evenly distributed around the axis of the tool body 1, and the four sensing parts 41 are arranged in a one-to-one correspondence with the four limiting holes 12, that is, the handle 2 can be adjusted in four directions. When the handle 2 is rotated to any direction, the start button 53 can be pressed to control the electric tool to perform surgical operations.
[0058] It is understandable that the handle 2 can be adjusted in four directions, which can basically meet the use requirements of the power tool. The adjustment directions of the handle 2 can also be increased by increasing the number of limiting holes 12 and sensing parts 41.
[0059] In the medical device of this embodiment, the medical device includes the above-mentioned electric tool, and the medical device also includes a mechanical arm, and the mechanical arm is fixedly connected to the tool body 1 through a quick-release portion 6 .
[0060] The electric tool of this embodiment is applied to medical equipment, and the tool body 1 is fixedly connected to the robotic arm. The doctor can rotate the handle 2 according to actual needs to change the direction of the handle 2 and perform surgical operations in a comfortable posture, thereby improving the doctor's operating comfort and the convenience of using the electric tool.
