Description

Tool with impact driver and universal screwdriver function

The present invention primarily discloses a tool having an impact driver and a universal driver function.

The screwdriver tool is used to turn the screw lock. When the screw lock is too tight, jammed or rusted, the screw can not be loosened by manual rotation, so the impact lock must be used to turn the screw.

Refer to China Patent Certificate No. M426473 "Improved Impactor Structure", which consists of a grip, a bushing, an elastic member, a tool head and a plug; the grip has an axial capacity at one end. The groove is provided, and the periphery of the grip is provided with a pin hole extending through the accommodating groove, and the grip is provided with a small diameter portion at the outer periphery of the pin hole, and the small diameter portion is provided for the bushing setting position, and the accommodating groove is provided for The elastic member and the tool head are mounted, and the outer periphery of the tool head is provided with a radial through hole, the jack has a first position and a second position, respectively, and the tool head is pressed against the elastic member, and the socket of the tool head can be The plug is passed through; wherein the tool head is provided with a ring recess on the outer periphery of the jack; thereby not only ensuring smooth operation, but also causing the tool head to be stuck, and no need to consume any pneumatic force, and having better labor-saving operation effect.

The aforementioned patent provides an impact driver with an impact effect, which can solve the screw lock when the screw lock is too tight, jam or rust. When the impact driver can drive the screw, the user must use a general screwdriver tool. It is indeed the purpose of loosening the screw lock to complete the disassembly. On the contrary, the screw lock is initially used first. After the lock, the impact method is used to strengthen the tight lock to prevent loosening. Therefore, during use, the user must alternate the impact screwdriver with the general screwdriver. For the user, a screwdriver tool cannot be used simultaneously for the impact screw screw and the complete screw screw, in the screw lock. In the process of the piece, the screwdriver tool needs to be replaced. The function end of the screwdriver is divided into a cross, a hexagonal type, a star type, and a size and a size. If the tool head has an impact screwdriver at the same time, the tool head with a general screwdriver is indeed complicated. It is inconvenient and wastes resources, but it is really inconvenient and necessary to improve.

The inventors have sought a solution in view of the lack of prior art.

The technical problem to be solved by the present invention is to provide a tool having an impact driver and a universal driver function, which can provide a screw-type screw lock which is convenient for the user.

The main technical improvement of the invention is that the tool of the invention has the functions of an impact driver and a universal screwdriver. During use, the user can simultaneously use the impact screw and the complete screw screw with a single tool. There is provided that the user does not need to have two screwdrivers for the impact driver and the universal screwdriver. The user avoids the inconvenience of replacing the screwdriver, and the user does not need to prepare two screwdrivers, which can really increase the convenience of use.

The technical means for the secondary improvement of the present invention is that the switching mode of the control loop is simple, and the user can move the control loop and rotate the control loop to complete the switching.

Another technical means for improving the present invention is that the control loop is limited by the limit. The bit groove limits the protrusion to achieve a true limit effect, so that the control ring is indeed in the first position without automatic switching.

Another technical means for improvement of the present invention is that when the control ring is in the first position, because the protrusion is restricted to the limit groove, at this time, rotating the control ring can drive the drive member to rotate synchronously, so that the control The ring can be used as a booster and has the utility of a universal screwdriver when used as an impact driver.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.

When the control ring 40 is in the first position, because the protrusion 304 is restricted to the limiting groove 413, the rotation of the control ring 40 can drive the driving member 30 to rotate synchronously, so that the control ring 40 can be regarded as When the aid is used and the tool 1 is used as an impact driver, it still has the function of a universal screwdriver.

The control ring 40 is axially moved to disengage the limit group 302 of the control ring 40 from the annular groove 42. The protrusion 304 is disengaged from the limiting groove 413, and the control ring 40 is rotated to position the protrusion 304. Bottom 411, the control ring 40 The second end surface 45 of one end of the control ring 40 is disposed at the first end surface 15 of the grip 10 , and the flat bottom portion 411 of the other end of the control ring 40 is disposed at the protrusion 304 , and the limit group 302 is separated from the ring groove 42 . The position group 302 and the blocking group 303 are disposed on the inner circumference of the control ring 40, so that the control ring 40 is restricted between the grip 10 and the driving member 30. At this time, the control ring 40 is located at the second position. In position, and the control ring 40 does not automatically disengage from the second position, the second end surface 45 of the control ring 40 is attached to the first end surface 15 of the grip 10, and the tool 1 is used as a universal screwdriver.

The control ring 40 has a simple switching mode, and the user can move the control ring 40 axially and rotate the control ring 40, that is, the switching can be completed. The control ring 40 limits the protrusion 304 by the limiting groove 413 to achieve a positive limit effect, so that the control ring 40 is indeed in the first position without automatic switching.

Referring to FIG. 9 , FIG. 10 and FIG. 11 , a schematic diagram of a tool for accepting an adapter with an impact driver and a universal screwdriver function is provided. The drive head end 31 of the drive member 30 of the tool 1 can receive the adapter 2, and the adapter 2 receives the driver head 3.

The driving head end 31 has a square head shape, and is capable of receiving various types of adapters 2 of different specifications, and each type of adapter 2 is capable of receiving different types of the driver heads 3, respectively.

Referring to FIG. 12, FIG. 13 and FIG. 14 , a schematic diagram of a tool having an impact driver and a universal starter function as an impact driver according to the present invention is shown. When the control ring 40 of the tool 1 is in the first position, the gap A is formed between the second end face 45 of the control ring 40 and the first end face 15 of the grip 10.

The driving member 30 is disposed on the elastic member 20, and the first insertion end 101 The first stop end portion 351. The user hits the impact end face 18 of the grip 10 with the hoe 4, and the grip 10 is moved toward the driving member 30. The first spigot 101 moves synchronously to drive the driving member 30 to rotate. The first stopping end The portion 351, the second stopping end portion 352 and the turning portion 353 selectively correspond to the first insertion end 101. When the driving member 30 rotates, the adapter 2 is rotated, and the adapter 2 synchronously drives the driver's head. 3 turns.

Referring to Fig. 15, Fig. 16 and Fig. 17, a schematic diagram of a tool having an impact driver and a universal starter function as a universal screwdriver is used. When the control ring 40 of the tool 1 is in the second position, the second end surface 45 of the control ring 40 abuts against the first end surface 15 of the grip 10 , and the protrusion 304 is limited to the flat bottom 411 .

When the user holds the grip 10 of the tool 1 , the first plug 101 of the grip 10 is idly rotated to the rotating guide groove 35 to abut the first stop end 351 or the second stop end. 352 (see FIG. 2), when the grip 10 rotates, the driving member 30 is further rotated, and the adapter 2 is rotated, and the adapter 2 synchronously drives the driver 3 to rotate.

As far as the above is concerned, it can be concluded that the present invention has the following advantages:
