[0026] A hand-held tool refers to a tool that is held and used by a user. The most common hand-held tool is a screwdriver. Hand-held tools are essential for repairing various sizes of mechanical and electronic equipment. In the case of a screwdriver, there are various types of screwdrivers with long and short handles and large and small heads. Usually, multiple screwdrivers need to be equipped to meet the applications in various usage scenarios.
[0027] Among them, the screwdriver used for repairing electronic equipment is a commonly used tool. When in use, the user will hold the handle of the screwdriver and drive the tip to rotate by rotating the handle to tighten or loosen the screw.
[0028] In the prior art, when a user uses a screwdriver for repairing an electronic device, the palm of the user's hand will abut against one end of the tool handle away from the tool tip, and the tool handle is rotated by the thumb, index finger, middle finger, etc. to tighten or loosen the screw. However, due to the different sizes of users' hands, it is not convenient to rotate the tool handle whether the hand is too large or too small. In addition, since some screw holes of the electronic device are located in relatively deep positions, the tool tip of the screwdriver needs to be inserted into the relatively deep screw hole, and currently only a special long tool tip screwdriver can be used for operation, and an ordinary screwdriver cannot be inserted into the relatively deep screw hole.
[0029] To solve the above problems, the present patent provides a handheld tool, aiming to enable the user to make adjustments when using the handheld tool and adjust it to the most suitable position for holding.
[0030] For ease of understanding, the following will describe in detail the specific implementation manners of the embodiments of the present application with reference to the accompanying drawings.
[0031] Please refer to Figure 1-2 , a handheld tool, including a tool handle 100 and a tool tip 200. The tool handle 100 includes a handle body 110 and a holding portion 120 sleeved on the handle body 110; the holding portion 120 is circumferentially fixed to the handle body 110; the holding portion 120 and the handle body 110 can slide relative to each other axially to change the relative position between the handle body 110 and the holding portion 120; the tool tip 200 is fixed to the handle body 110; the handle body 110 is provided as a cylinder or has a cylindrical part, and the cross-section of the handle body 110 or its cylindrical part perpendicular to the axial direction of the handle body 110 is non-circular; the holding portion 120 is adapted to the outer peripheral surface of the handle body 110 or its cylindrical part.
[0032] In this embodiment, the tool tip 200 refers to the part that can enter a narrow space and plays the main role of the tool, such as the part of a crowbar for prying an object and the part of a cutter for cutting an object, etc., and it is not limited to the tool tip 200 of the screwdriver. The holding portion 120 is circumferentially fixed to the handle body 110, so that the holding portion 120 is not easy or cannot rotate relative to the handle body 110. The holding portion 120 can slide axially relative to the handle body 110, so that the user can move the holding portion 120 to different positions of the handle body 110 according to actual needs. For example, if the user's hand is relatively large, the holding portion 120 can be moved to a position close to the tool tip 200. The position-variable holding portion 120 enables the user to make adjustments according to their own needs and adjust to the most suitable position for holding. By finally driving the tool tip 200 to rotate through the holding portion 120, the diameter of the handle body 110 can be set to be smaller. In the embodiment where the tool tip 200 is fixed to the handle body 110, the distance from the tool tip 200 to the holding portion 120 can be extended by moving the holding portion 120 upward. And the relatively thin handle body 110 can be inserted into a smaller hole, so it is equivalent to extending the tool tip 200 and making it can be used as a long tool tip tool.
[0033] The cross-section of the handle body 110 or the cylindrical part of the handle body 110 (the cross-section is perpendicular to the axial direction of the handle body 110) is non-circular, so that the holding part 120 is not easy or unable to rotate relative to the handle body 110. In this embodiment, the implementation manner of the cross-section is not limited. Preferably, it can be a polygon, an ellipse, a wavy shape, a petal shape, etc. The holding part 120 is adapted to the outer peripheral surface of the handle body 110 or the cylindrical part of the handle body 110, so that when the holding part 120 moves relative to the handle body 110, it will not be hindered by the handle body 110. In addition, anti-slip grooves are provided on the outer surface of the holding part 120 for the user to twist the holding part 120.
[0034] It should be noted that based on the technical solution that the holding part 120 and the handle body 110 can slide relative to each other along the axial direction, further, there is a technical problem of how to keep the holding part 120 in place after it moves to the required position.
[0035] To solve the above problems, the present application provides two preferred implementation manners.
[0036] Method 1.
[0037] Optionally, the holding part 120 is made of a soft material.
[0038] In this embodiment, the holding part 120 is made of a soft material, so that a large maximum static friction force can be generated between the holding part 120 and the handle body 110. Thus, after the holding part 120 moves to the required position, it can stay in that position. Only when an additional large axial force is applied can its position be changed. During normal use, its position remains fixed relative to the handle body 110.
[0039] Method 2.
[0040] Optionally, the holding part 120 includes an outer layer and an inner layer, and the inner layer of the holding part 120 is made of a soft material.
[0041] In this embodiment, the inner layer of the holding part 120 is made of a soft material, so that a large maximum static friction force can be generated between the holding part 120 and the handle body 110. Thus, after the holding part 120 moves to the required position, it can stay in that position. And the outer layer of the holding part 120 can be made of a hard material such as metal to obtain a better holding feel.
[0042] It should be noted that based on the technical solution that the tool head 200 is fixed to the handle body 110, further, there is a technical problem of how to fix the tool head 200 to the handle body 110. To solve the above problems, the present application provides a preferred implementation manner.
[0043] Please refer to Figure 3, the handle body 110 is set to be cylindrical, a tool head mounting portion 111 is provided at the lower end of the handle body 110, and the tool head 200 is fixed to the handle body 110.
[0044] In this embodiment, the tool head mounting portion 111 is provided at the lower end of the handle body 110, so that the tool head 200 can be fixed to the handle body 110.
[0045] It should be noted that, based on the technical solution that the tool head 200 is fixed to the lower end of the handle body 110, further, there is a technical problem of how to prevent the holding portion 120 from sliding out of the lower end of the handle body 110. To solve the above problem, the present application provides a preferred implementation.
[0046] Optionally, a stop portion is provided at the lower end of the handle body 110, and at least a part of the outer side surface of the stop portion protrudes from the outer side surface of the handle body 110.
[0047] In this embodiment, at least a part of the outer side surface of the stop portion protrudes from the outer side surface of the handle body 110, so that when the holding portion 120 slides to the position of the stop portion, the holding portion 120 will be blocked by the stop portion, and the holding portion 120 cannot continue to slide in this direction, thereby preventing the holding portion 120 from sliding out of the lower end of the handle body 110. In addition, in an embodiment without a stop portion or an embodiment with an adjustable stop portion, the holding portion 120 can be completely removed from the lower end of the handle body 110, which is convenient for replacing the holding portion 120 of different sizes to make it more in line with the user's usage habits.
[0048] It should be noted that in addition to the above implementation of the holding portion 120, there are other implementation manners for keeping the holding portion 120 in place after it moves to the desired position. The specific implementation manners to meet the above requirements are not limited in this embodiment. For the convenience of understanding, the present application provides a preferred implementation.
[0049] Optionally, the holding portion 120 is provided with a movable locking structure, and the locking structure is used to lock the holding portion 120 to the handle body 110 or release the holding portion 120 from the handle body 110.
[0050] In this embodiment, the holding portion 120 is provided with a movable locking structure, so that the holding portion 120 can be locked to the handle body 110, or released from the handle body 110 to slide relative to the handle body 110. Thus, when the holding portion 120 moves to the desired position, it can be kept in that position.
[0051] It should be noted that in a specific scenario, when a user uses a hand tool, it is necessary to rotate the hand tool while holding it against an object. This operation method is difficult and not easy for the user to perform. Therefore, the hand tool needs to be convenient for this operation. The specific implementation manners to meet the above requirements are not limited in this embodiment. For the convenience of understanding, the present application provides a preferred implementation.
[0052] See also Figure 1-2 The upper end of the handle body 110 is provided with a supporting portion 112 which can rotate relative to the handle body 110 .
[0053] In this embodiment, a supporting portion 112 is provided at the upper end of the handle body 110 and can rotate relative to the handle body 110, so that the user can use the palm of his hand to support the supporting portion 112, thereby supporting the hand tool. At the same time, the user can achieve the effect of rotating the hand tool by rotating the supporting portion 112. Furthermore, the cross section of the supporting portion 112 perpendicular to its axial direction can be set to be larger than the cross section of the handle body 110 perpendicular to its axial direction, so as to reduce the pressure of the user against the supporting portion 112. In addition, the supporting portion 112 is provided at the upper end of the handle body 110, which can also achieve the technical effect of preventing the grip portion 120 from slipping out of the upper end of the handle body 110.
[0054] In summary, the present invention provides a handheld tool, comprising a handle 100 and a blade head 200. The handle 100 comprises a handle body 110 and a gripping portion 120 sleeved on the handle body 110. The gripping portion 120 is circumferentially fixed to the handle body 110. The gripping portion 120 and the handle body 110 can slide relative to each other along the axial direction to change the relative position of the handle body 110 and the gripping portion 120. The blade head 200 is fixed to the handle body 110. The handle body 110 is configured to be cylindrical or has a cylindrical portion, and the cross section of the handle body 110 or its cylindrical portion perpendicular to the axial direction of the handle body 110 is non-circular. The gripping portion 120 is adapted to the outer circumference of the handle body 110 or its cylindrical portion. In this way, the user can adjust the handheld tool to the most suitable position for him / her when using it.
[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
