Description

M254304 V. Creative Instructions (i) [Technical Field] This creative department provides a replaceable ratchet wrench (1), especially a tool head with a control block, a lever, a positioning element, an elastic element, and a buckled ring for positioning. Products, the left, right and center positioning are directly generated by the control block, and the control lever uses the saddle-shaped structure of the locking pin and the control block to produce stable rotational positioning; therefore, the original wrench body can be quickly replaced with a variety of different ^ inches And style tool heads, and the positioning and operation of the tool heads are very stable. 0 With the increase in the use and exquisiteness of hand tools in the prior art, the requirements of hand tool functions have generally increased. Diversity ', but how to develop a wheel wrench that can make the operation of ratchet wrenches strong and polite ~ One of the most important issues at present. The stability has also increased, that is, most of the tools on the market today that have only a single specification can only lock components of one size (such as a ratchet wrench with screws ^), so the work is being carried out. ) Locking requires the preparation of multiple ratchet wrenches of different sizes in advance, ah, the user will replace it, and the applicability of this mainstream product is obviously inadequate; The control lever of the conventional product is M254304 V. Creation instructions (2) The operation pivot is set on the wrench body, but because the control lever will be continuously operated by the user, and the riveting part often receives a lot of rotational stress, the conventional control The problem of shedding and loosening caused by insufficient bonding strength often occurs in the riveted part of the rod. Another problem of conventional products is that the control elements between the control rod and the ratchet are larger and more complicated components, which cause high costs and difficult assembly. In addition, only one side of the tool head of a conventional product can work, and the other side is assembled in the body of a ratchet wrench. Therefore, the scope of application of conventional product tool heads is still not large; therefore, 'if a product with a single ratchet wrench body and various tool head accessories of different sizes can be developed, and it can produce a combination strength and stability that meets user needs , Then this innovative product can completely overcome the shortcomings mentioned above.

The purpose of this creation is to provide a replaceable ratchet wrench (1, the tool head can be positioned on the ratchet wrench body with the same size and different functions by the buckle, which effectively improves the ratchet. M254304 V. Creation Instructions (3 ) Into the end, the bayonet can not only restrict the positioning of the control block to operate in the ratchet wrench body, but the bayonet is also embedded in the groove of the control block, which can improve the control block and the lever during operation. Combining strength. Another purpose of this creation is to provide a replaceable ratchet wrench (1) that can stably position the control block in the left, right, and center positions. Because this work often replaces tool heads of different sizes and functions, Therefore, the 栌: In addition to the left and right positions of common products, it must have '疋 positioned in the central position (easy to disassemble the tool head), and this creative use ^: the manufacturing structure should correspond to the positioning element And the elastic element rotates and fixes the second H 5 ^ # against the central depression of the light structure, it will stably position the control block in the center.

The middle depression (6 3 1) ^ uy | ^, 〇 1 χ X ^ dagger; Han You depression guang q 3); the above is the main relationship position of this creative embodiment. Reciprocity of the mold [Implementation] In order to clearly explain the action and effect of this creation, please cooperate with the drawings and the following descriptions, I believe that we will have a deeper understanding of the substantial structural innovation of this creation: / Please refer to the second, As shown in the three pictures, after the user of this creative rotates the handle (4 1) of the control lever (40) to the left and right, the pivot (4 2) and the latch (50) of the control lever (40). ) Will synchronously drive the control block (60) to rotate, and the control block (60) is positioned by the positioning element (80) and will be positioned in an oblique left or right inclined state (the positioning element (80) is smooth) End against the left recess (6 3 2) or right recess (6 3 3) of the saddle structure (6 3) and the left latch teeth (6 1) or right latch of the two sides of the control block (60) The tooth (62) will also unilaterally couple the tool head (30), 2 ratchet teeth (31), so that this creation can be operated on one side under the stable positioning of the positioning element (80); it is worth mentioning that Due to the way that the latch (50) abuts against the abutment groove (65) of the control block (60), the control lever (40) and the control block (60) of this creation can be more Stable and stronger combined operation. Therefore, this creative joystick has a stronger binding degree than conventional products.

M254304 V. Creation instructions (7) Next, please refer to the fourth figure, 'When the user rotates the lever (4 1) of the control lever (40), the pivot of the control lever (40) The shaft (42) and the latch (50) will synchronously drive the control block (60) to rotate to the middle, and the control block (60) is positioned at the center by the positioning element (80) (the positioning element (8 0) The round end abuts against the middle depression (6 3 1) of the saddle structure (6 3). At this time, the left and right teeth (6 1) and the right teeth ( 6 2) are unable to engage the ratchet teeth (3 1) of the tool head (30), so the user can push against the tool head (3 0) with force to disengage the tool head (30) from the buckle (2 0), and let the tool head (30) be taken out from the pivot hole (1 1 2) of the accommodation space (1 1 1) of the wrench body (ι〇) (the tool head (3 0) is assembled Reversely insert into the pivot hole (1 1 2) for positioning); By doing this, the author can replace the tool heads with different sizes and different functions to meet the needs of the work, effectively improving the applicability of the ratchet wrench. Finally, please refer to the embodiment of the present invention shown in the sixth figure. In this case, a certain stand # (1 2 1) can be opened at the end of the handle (1 2) of the wrench body (10), and the positioning groove ( 1 2 1) A set is connected to a set of three-stage ^ wheels (90), and the three-stage ratchet (90) is composed of a core rod (2), a two-card block (9 2), a control ring (9 3) and a ratchet sleeve (9 4); a two-volume sample (9 1 1) formed by the mandrel (9 1) is used to pivot the clamping block (9 2) and use The control ring (9, 3) controls the swing angle of the card-making block (9 2), so that it has positive and negative directions.
