Those skilled in the art will realize that the application is readily applicable to other embodiments and / or combinations of parts well known in the art, and numerous modifications and changes in detail can be made without departing from the spirit of the application. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive. DETAILED DESCRIPTION

[0040] In the work of assembling or repairing electronic products such as mobile phones, computers, watches, etc., precision screwdrivers are usually used. In the related art, some precision screwdrivers include a handle, the front part of the handle is provided with an anti-skid section, and the tail end of the handle is provided with a rotatable tail cover. When a user uses the precision screwdriver, one method is that the screwdriver head is placed against a screw to be disassembled, the tail cover is placed in the palm of the user, the little finger, ring finger and middle finger of the user are held on the tail cover and the tail part of the handle, and the thumb and index finger of the user are pinched on the anti-skid section of the handle and the anti-skid section is rotated, that is, the handle is rotated, so as to disassemble the screw. In the related art, in order to make the user use the precision screwdriver comfortably, the length of the handle is usually set according to the size of the user's hand, so the length of the handle is usually not too short. If the length of the handle is too short, the user will not use the precision screwdriver comfortably, and if the length of the handle is too long, the precision screwdriver will occupy a large space and is inconvenient to store.

[0041] Therefore, the present application sets a chuck between the tail cover of the screwdriver and the pinching part for the user to pinch, and sets a telescopic extension rod in the chuck, so that the length between the pinching part and the tail cover is adjustable. Thus, in the storage state, the extension rod is stored in the chuck and the pinching part, so the overall length of the handle of the screwdriver is shorter and the precision screwdriver occupies a small space when stored, which is convenient to store. When used, the user can adjust the length of the extension rod according to the size of the user's hand, and after the length of the extension rod is adjusted, the chuck locks the position of the extension rod. The user adjusts the length of the handle of the screwdriver according to the size of the user's hand, so that the user can use the handle of the screwdriver more comfortably, which greatly improves the comfort of the user using the handle of the screwdriver.

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0043] As Figure 1 , Figure 2 and Figure 3As shown, the screwdriver handle provided by the embodiment of the application comprises a holding part 100, an extension rod 300 and a chuck 200. The holding part 100 is used for being held and rotated by a user. The holding part 100 has opposite first and second ends 110 and 120. The first end 110 is provided with a first insertion hole 130. The first insertion hole 130 is configured to be inserted with a tool head 400. The shape of the first insertion hole 130 matches that of an insertion end of the tool head 400. The second end 120 is provided with a mounting hole 140. That is, the first insertion hole 130 is an insertion hole of the tool head 400. The tool head 400 is exemplarily a screwdriver head (drill bit), a sleeve or the extension rod 300. When the tool head 400 is exemplarily a screwdriver head (drill bit), a sleeve or the extension rod 300, the insertion end of the tool head 400 is a hexagonal structure. The first insertion hole 130 is a hexagonal structure matching the tool head 400. After the tool head 400 is inserted into the first insertion hole 130, the tool head 400 cannot rotate axially around the first insertion hole 130 in the first insertion hole 130. The tool head 400 can also be of other special-shaped structures such as a quadrilateral structure or a pentagonal structure.

[0044] In the embodiment, the extension rod 300 has opposite third and fourth ends 310 and 320. The third end 310 is provided with a tail cover 330. The chuck 200 is connected to the holding part 100. The chuck 200 is provided with a through hole 210. The through hole 210 and the mounting hole 140 are through. The through hole 210 and the mounting hole 140 are configured to be inserted with the extension rod 300. The chuck 200 has a locking mechanism. In an unlocked state of the locking mechanism, the extension rod 300 can move axially in the through hole 210. In a locked state of the locking mechanism, the position of the extension rod 300 is locked. That is, the extension rod 300 can be inserted into the through hole 210 and the mounting hole 140. The extension rod 300 can be telescoped in the through hole 210. In a storage state, the extension rod 300 is stored in the through hole 210 and the mounting hole 140. Thus, the overall length of the screwdriver handle is relatively short. The screwdriver handle occupies a small space when stored and is convenient to store. When used, the user can adjust the length of the extension rod 300 extending out of the through hole 210 according to the size of his hand. After the length of the extension rod 300 extending out is adjusted, the chuck 200 locks the position of the extension rod 300. The user adjusts the length of the screwdriver handle according to the size of his hand. Thus, the user can use the screwdriver handle more comfortably. The comfort of the user using the screwdriver handle is greatly improved.

[0045] Exemplarily, the structure of the extension rod 300 matches the chuck 200, which can be the chuck 200 used for clamping the telescopic screwdriver rod at the front end of the screwdriver handle in the related art, that is, the screwdriver bit can be telescoped in the chuck 200 to adjust the length of the screwdriver bit extending out of the screwdriver handle (the chuck 200), that is, the chuck 200 includes an inner support, a sliding sleeve, a spring, and a ball, and the inner support has a through hole 210. The structure of the rod part of the extension rod 300 can be the structure of the rod part of the telescopic screwdriver rod in the related art, that is, a plurality of annular grooves are arranged at intervals in the length direction of the rod part. When the screwdriver handle and the telescopic screwdriver rod are used together in the related art, the telescopic screwdriver rod extends into the through hole 210, the sliding sleeve of the chuck 200 slides on the inner support, and the ball is controlled to extend into or move out of the annular groove to lock or unlock the telescopic screwdriver rod, that is, when the telescopic screwdriver rod needs to extend to a longer length, the sliding sleeve is moved inward, the telescopic screwdriver rod is pulled out, after the telescopic screwdriver rod is pulled out to a certain length, the sliding sleeve is loosened, the sliding sleeve is reset, and the telescopic screwdriver rod is locked. When the telescopic screwdriver rod needs to be retracted to reduce the length of the telescopic screwdriver rod extending out, the sliding sleeve is moved inward, the telescopic screwdriver rod is pushed inward, after the telescopic screwdriver rod is pushed inward to shorten to a certain length, the sliding sleeve is loosened, the sliding sleeve is reset, and the telescopic screwdriver rod is locked. Similarly, in this embodiment, when the extension rod 300 is used with the chuck 200, the extension rod 300 extends into the through hole 210, the sliding sleeve of the chuck 200 slides on the inner support, and the ball is controlled to extend into or move out of the annular groove to lock or unlock the extension rod 300. That is, when the chuck 200 is the chuck 200 in the related art, the sliding sleeve is moved inward to the first position, the locking mechanism is in the unlocked state, and the sliding sleeve is reset to move to the second position, the locking mechanism is in the locked state.

[0046] Exemplarily, the chuck 200 has an insertion shoulder end, which is inserted into the mounting hole 140 and connected with the side wall of the mounting hole 140 in an interference fit to realize the connection of the chuck 200 and the pinch part 100.

[0047] It should be noted that in this embodiment, the structure of the chuck 200 and the extension rod 300 can adopt other chuck 200 structures capable of clamping, locking, and unlocking the extension rod 300 in addition to the chuck 200 used for clamping the telescopic screwdriver rod at the front end of the screwdriver handle in the related art and the structure of the rod part of the telescopic screwdriver rod, which is not limited here.

[0048] Exemplarily, as shown in FIG. 6, the chuck 200 includes an inner support 210, a sliding sleeve 220, a spring 230, and a ball 240. Figure 3As shown, the tail cover 330 includes a support connecting part 332 and a cap 333 rotatably connected to the support connecting part 332, and the support connecting part 332 is connected to the third end 310 of the extension rod 300. The cap 333 is rotatably connected to the support connecting part 332, which makes the user more comfortable when using the screwdriver handle with a screwdriver handle, and the user can use the index finger or palm to press against the cap 333, rotate the pinch part 100, and facilitate positioning when using the screwdriver, and use more stably.

[0049] For example, the support connecting part 332 is provided with an annular groove, and a rotating ring 334 is arranged in the annular groove. The rotating ring 334 can rotate around the length direction of the extension rod 300, and the cap 333 is fixedly connected to the rotating ring 334 and rotates with the rotating ring 334. For example, the cap 333 is in interference connection with the rotating ring 334.

[0050] For example, the outer side of the pinch part 100 is provided with anti-skid lines 150. The anti-skid lines 150 are arranged to facilitate the user to rotate the pinch part 100 and reduce slipping during rotation. When the user uses the operation method in the background art to operate the screwdriver, the length of the extension rod 300 can be adjusted according to the size of the user's hand to achieve comfortable operation of the screwdriver. Since the distance between the pinch part 100 and the tail cover 330 is adjustable, the length of the pinch part 100 only needs to meet the length of the user's pinch, and does not need to be too long. Therefore, the overall length of the screwdriver handle is relatively short, and the screwdriver handle is more compact and flexible, and is convenient to store. For example, the length of the anti-skid lines 150 in the axial direction of the first insertion hole 130 is 1.5 cm-2.5 cm. For example, the length of the anti-skid lines 150 is 1.5 cm, 2.0 cm or 2.5 cm.

[0051] In some embodiments of the present application, the third end 310 of the extension rod 300 is provided with a plug-in part 340, the plug-in part 340 is provided with a second insertion hole 341, the second insertion hole 341 is configured to be plugged into the tool head 400, and the shape of the second insertion hole 341 matches the insertion end of the tool head 400. For example, the insertion end of the tool head 400 is a regular hexagonal structure, and the second insertion hole 341 is a regular hexagonal structure matching the tool head 400. After the tool head 400 is inserted into the second insertion hole 341, the tool head 400 cannot rotate around the second insertion hole 341 in the axial direction of the second insertion hole 341. For example, the insertion end of the tool head 400 can also be other special-shaped structures, such as quadrilateral, pentagonal, etc. The tail cover 330 includes a plug-in rod 331 arranged on one side of the support connecting part 332, and the shape of the plug-in rod 331 is the same as that of the insertion end of the tool head 400. The tail cover 330 is plugged into the second insertion hole 341 through the plug-in rod 331, and the tail cover 330 can be plugged into the first insertion hole 130 through the plug-in rod 331. That is, the screwdriver handle provided by the embodiments of the present application has three states, such as Figure 1As shown, the first state is a storage state, that is, the extension rod 300 is stored in the through hole 210 and the mounting hole 140; as Figure 2 As shown, the second state is a holding and rotating use state, that is, the extension rod 300 is extended from the through hole 210 by a certain length, so as to be suitable for a user to operate the screwdriver handle by using the background technology operation method, or to use the holding operation method, that is, the screwdriver head is abutted on the screw to be disassembled, the tail cover 330 is abutted on the palm, the little finger, the ring finger and the middle finger cooperate with the palm to hold the tail part of the screwdriver handle, and the thumb and the middle finger are pinched in the holding part 100 and rotate the holding part 100, that is, rotate the handle, so as to disassemble the screw; as Figure 4 As shown, the third state is an extension use state, when some screws are disassembled, the user can pull out the tail cover 330 from the second insertion hole 341, and then insert the tail cover 330 into the first insertion hole 130, at this time, the second insertion hole 341 serves as the insertion hole of the tool head 400, at this time, the extension rod 300 serves as the lengthening rod of the tool head 400, and the tool head 400 cooperates with the extension rod 300 to lengthen the length of the tool head 400, so that the screwdriver can be used to disassemble some screws in a narrow space or a deep hole. The setting increases the function of the screwdriver handle, so that the screwdriver handle is suitable for more use scenarios and is more flexible and variable.

[0052] In some embodiments of the present application, a magnetic member is arranged at one end of the second insertion hole 341 away from the opening, and the magnetic member is used to adsorb the tool head 400 installed in the second insertion hole 341, so as to avoid the tool head 400 installed in the second insertion hole 341 from falling out of the second insertion hole 341.

[0053] In some embodiments of the present application, a magnetic member is arranged at one end of the first insertion hole 130 away from the opening, and the magnetic member arranged in the first insertion hole 130 is used to adsorb the tool head 400 installed in the first insertion hole 130, so as to avoid the tool head 400 installed in the first insertion hole 130 from falling out of the first insertion hole 130.

[0054] In order to make the length of the extension rod 300 extending out of the through hole 210 as long as possible, the length of the extension rod 300 is the sum of the first length and the second length, the first length is the axial length of the through hole 210, and the second length is the distance between one end of the through hole 210 away from the tail cover 330 and one end of the mounting hole 140 away from the tail cover 330. That is, the internal space of the holding part 100 is also utilized in the embodiment, so that a part of the extension rod 300 is stored in the internal space of the holding part 100, thereby the length of the extension rod 300 can be increased as much as possible.
