Description

A kind of labour-saving multifunctional wrench

【Technical field】

Machining tools art is the utility model is related to, more particularly to a kind of labour-saving multifunctional wrench.

【Background technology】

Spanner is a kind of common installation and extracting tool.Bolt, screw, nut and other spiral shells are twisted using lever principle Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually formed with clamp holder in the one or both ends of shank Portion applies external force shank and applies external force, and the opening or sets of holes of bolt or nut are held with regard to that can twist bolt or nut.Along spiral shell during use Line direction of rotation applies external force in shank, with regard to that can twist bolt or nut.

Existing functions of wrench is relatively simple, and the spanner having use it is relatively elaborate, it is more effortless in order to more convenient Work, reached raising work efficiency, for this it is proposed that a kind of labour-saving multifunctional wrench.

【Utility model content】

The main purpose of the utility model is that providing a kind of labour-saving multifunctional wrench, background technology can be effectively solved Middle function is relatively simple, uses the problem of relatively elaborate.

To achieve the above object, the technical solution that the utility model is taken is：

A kind of labour-saving multifunctional wrench, including handle a, sleeve, internal angle wrench and shfting wrench, the top of the handle a Portion is provided with sleeve, and the outer wall lower end of the handle a offers through hole, and handle b is plugged with the through hole, the handle b's Right end is connected through through hole with the left end of handle c, and the right end of the handle c is connected with shfting wrench, and the left end of the handle b is opened Internal angle wrench is plugged with fluted a, the groove a, limited block, the right side of the handle b are arranged with the handle b outer walls End offers threaded hole.

Further, the upper end of the handle c is provided with bolt, and the bolt outer wall is provided with the internal thread with threaded hole The external screw thread being meshed, opens up fluted b at the top of the bolt, screwdriver is plugged with the groove b.

Further, the sleeve lining is placed equidistant with three shafts, and latch block is provided with the top of the shaft, described Spring shim is connected with the left of latch block, the left end of the spring shim is fixedly connected on fixed block, and the fixed block is consolidated Surely it is connected on sleeve lining, the right end of the latch block is connected with limited block, and the limited block is fixedly connected on sleeve lining On.

Further, the barrel bore is provided with gear, and the external tooth of the gear is engaged with latch block, the gear Outer wall offers five jiaos of through holes.

Compared with prior art, the utility model has the advantages that：The apparatus structure is simply easy to operation, due to Conventional functions of wrench is relatively simple, in use, the suitable spanner of searching that will be repeated, loses time, unexpected spanner power Arm is fixed, and use is harder, using a kind of labour-saving multifunctional wrench, by the spanner similar to ratchet in sleeve, reaches province The effect of power, by that can be slidably reciprocated in through hole by handle b and handle c, increases the arm of force, reaches labour-saving effect, the dress Putting not only can have box spanner to also have shfting wrench and internal angle wrench, function diversification.

【Embodiment】

To make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, below With reference to embodiment, the utility model is expanded on further.

As shown in Figs. 1-3, a kind of labour-saving multifunctional wrench, including handle a1, sleeve 2, internal angle wrench 8 and the survivor of a murder attempt pull Hand 5, is provided with sleeve 2 at the top of the handle a1, the outer wall lower end of the handle a1 offers through hole 3,3 interpolation of through hole The right end for being connected to handle b6, the handle b6 is connected through through hole with the left end of handle c21, the right end connection of the handle c21 There is shfting wrench 5, the left end of the handle b6, which is provided with groove a7, the groove a, is plugged with internal angle wrench 8, the handle b6 Limited block b20 is arranged with outer wall, the right end of the handle b6 offers threaded hole 4.

Wherein, the upper end of the handle c21 is provided with bolt 9, and 9 outer wall of bolt is provided with the interior spiral shell with threaded hole 4 The external screw thread 10 that line is meshed, the top of the bolt 9 open up fluted b11, screwdriver 12 are plugged with the groove b11.

Wherein, 2 inner wall of sleeve is placed equidistant with three shafts 16, and the top of the shaft 16 is provided with latch block 17, The left side of the latch block 17 is connected with spring shim 18, and the left end of the spring shim 18 is fixedly connected on fixed block 19, The fixed block 19 is fixedly connected on sleeve lining, and the right end of the latch block 17 is connected with limited block a15, the limited block A15 is fixedly connected on 2 inner wall of sleeve.

Wherein, 2 inner cavity of sleeve is provided with gear 13, and the external tooth of the gear 13 is engaged with latch block 17, the tooth The outer wall of wheel 13 offers five jiaos of through holes 14.

Operation principle：When staff carries out dismounting work, it is necessary to when using sleeve 2, sleeve is first placed on bolt On, the handle b6 to link together and handle c21 are pumped on one side, increases the arm of force, has reached labour-saving effect, made in sleeve 2 To be engaged by latch block 17 with gear 13, when firmly unloading, it is spacing that latch block 17 is limited block 20, so that rotated with moving gear 13, So that screw rotates, a circle can not be rotated because the arm of force is long, when no space is, 2 opposite direction of sleeve is rotated, is blocked at this time The meeting holddown spring of tooth block 17 gasket 18, so that latch block 17 will not be engaged with gear 13, so that gear will not be driven to rotate, Screw will not be tightened because opposite direction rotates, which can not only use sleeve 2, while when needing different size of spanner, Shfting wrench 5 can be used, while also has internal angle wrench 8 to use, internal angle wrench 8 is drawable, changes different size of grafting In in groove a7, while the screwdriver 12 of institute's band on handle c can be used, while screwdriver can replace variety classes, the dress Put simple in structure, easy to operation, the labour-saving effect reached, function diversification, saves the time, improves work efficiency.
