TW200906564A - Three-side clamping spanner - Google Patents

Abstract

Disclosed is a three-side clamping spanner, comprising a main body and a hold-on set, a clamping set, and a driving set arranged in the main body. The clamping set comprises three pawls extending through the hold-on set and a clamping opening defined among the pawls. The driving set comprises a driving piece that closes the main body and allows for rotations with limited angles. The driving piece moves the pawls circumferentially around an axis in an equal distant manner to reduce/expand the size of the clamping opening, making the pawls clamping a threaded member. As such, the present invention is suitable for threaded members of different sizes and specifications, making the present invention practical and convenient in operation.

Description

200906564 IX. Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a type of wrench that can be screwed or loose. The invention relates to a wrench capable of three-sided holding of a wrench release screw. [Prior Art] η 2 is an example of a soil containing a eagle and a shaft joint extending at the end of the body u-. Shuai ^ 可 可: Do not fit with the sleeve 2 of different jaw sizes, whereby the wrench ^ replaces the sleeve 2 of different operating specifications, and thus with different sizes of screws such as screw and bolt ) The purpose of tightening the screw is to achieve the purpose of tightening the screw. However, the wrench 1 can change the operating specifications, but it must be repeatedly disassembled and smashed into different sizes of sleeves 2' and equipped with a plurality of sleeves 2: Screws of different sizes will not only cause problems in carrying and storage, but the operation is quite inconvenient. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a wrench capable of three-sided clamping with an adjustable operating specification. - I then, the three-sided clamping wrench of the present invention comprises a body, a mountain brake set, a clamping set, and a drive set. The body has a body formed at one end. The consistent hole of 卩. The brake set is disposed within the through hole of the body. The clamping member has three jaws that pass through the brake group, and a jaw defined between the jaws. Each jaw has a clamping portion that passes through the body, and is placed at 4 The guide inside the body shell. The driving group has a _ driving member that closes the two holes of the body 200906564 and can be rotated at a limited angle, and the shaft member=the number of interlocking portions of the bottom surface that are contacted by the claw guiding portions, 1 :::::: The moving angle drives the jaws around the axis and the green: + The effect of listening is to borrow. A _h is called 丨 从 from the kiss, the caliber of the claws: use different specifications of the screw to improve the operation time. Convenience and practicality. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Referring to Figures 2, 3 and 4', a preferred embodiment of the present invention for a three-sided clamping wrench includes a body 3, a brake assembly 4, a clamping set 5, and a drive assembly 6. The body 3 has a head portion 31 formed at one end portion, a shank portion 32 formed at the other end portion, and a constant hole 33 extending through the head portion 31 along an axis X. The brake group 4 is disposed on the body The through hole 33 of the third hole 33 has a brake member 41, a ratchet gear 42, a three-pad block 43, and a three-bolt member 44. The brake member 41 is spaced apart from the upper and lower sides of the spur gear 42 and has three through holes 411 and 421 corresponding to the upper and lower sides, and an edge 412, 422. The perforations 411, 421 are respectively equiangularly distributed and extend from one end adjacent the axis X along a straight track to the other end adjacent the edges 412, 422. The spacers 43 are received between the ratchet gear 42 and the brake member 41. The bolts 44 are respectively threaded through the brake member 41 and the spacers 43 and are screwed with the 200906564 ratchet gear 42 to cause the brake member 41, the ratchet gear 42 and the pads to be screwed. Block 43 is consolidated into one. The two holding jaws have three jaws 51' and a clip 52 defined between the jaws 51. Each of the female jaws 5 has a guiding portion 5 ι which passes through the through hole 421 of the ratchet gear 42 and passes through the body 3, a guiding portion 512 that passes through the 33 and passes through the shaping hole 411, and is formed. ^ Holding. The two fins 513 between the cymbal 5U and the guide portion 512 and piercing the spur gears 411, 421 across the brake member 41. The drive group 6 has a right one V4. y: Λ 61β_ "wired member 61 and - pressing member 62. The body 3 has a through hole 33 and can be rotated at a limited angle, and has a number of recesses on the bottom surface and engaged with the guide portion M2 of the jaws 51: 612. The linking portion 611 is adjacent to the axis χ

Lr;: extending adjacent to the other end of the edge 612. The ^X amp& feed line X passes through the driving member 61, and has a starting portion 62 j' and a bud d 3 hai rushing member 61 exposed outside the driving member 61 and the smashing member 41 The limit of the screwing...the hinge portion 622 is hard...the starter portion 621 is fitted to the limit body 3. The actuating member 61 and the brake member 41 are fastened to the reference FIG. 4 and FIG. y_L. Λ. In use, the pressing member 62 and the moving portion 621 are only required to be rotated, and the pressing member 62 is released and released. In the case of the soil and the forced state, the driving member 61 can be tilted in the direction of the counter-needle in the case of the chasing member 62, the (four) moving member 61, and the counterclockwise side μ', without departing from the braking member 41. In the process, God's pride, * & 句 〇丄 捉 捉 、 、 、 粒 粒 粒 粒 粒 改变 改变 角 角 角 角 角 角 角 角 角 角 角 角 角 角 角 角 角 角 角 角 ' ' ' ' ' ' ' ' ' 亥 亥The axis X is the center and the like 7 200906564 = ::, and after the diameter of the jaw 52 is reduced to a predetermined size, the 5-sea pressing member 62 is tightened, and the life-stopping projection $ 621 is fitted with the limiting portion 022. The driving member 61 is tightly pressed, and the 61 and 5th brake members are fastened to the body 3, and the small diameter cavities 52 can be coupled with the screw 71 having a smaller outer diameter. The purpose of rotating the screw 71 is achieved by the clamping portion of the jaws 51 being forced to abut the screw circumference. The member 61 refers to: 2, 7 and 8 when the pressing member 62 is released.
