Description

The torque alarming structure of switching hand-held tool

Technical field

It is espespecially a kind of to deform and send the sound using shell fragment the present invention relates to a kind of switching hand-held tool Reach the torque alarming structure of the switching hand-held tool of warning function.

Background technology

Switching hand-held tool is pulled using lever principle to screw tightening, reaches what is tightened or unscrew Effect, so as to which the spare part of all kinds of industries, general industry finished product are assembled, combined by screw tightening Various screw tightening is needed to use because of architectural difference, strong and weak different torsion assembling is imposed and fixes, It is insufficient or too big such as to pull the power of screw tightening, is likely to cause structure to lose effect with screw tightening With or damage, and switching hand-held tool is exactly the key for playing the part of control torsion, therefore switching hand-held tool The design relevant with torsion control is always the emphasis of industry exploitation, and market is just released frequently New structure.

The torque alarming structure of switching hand-held tool in currently available technology, there is composition structure mostly The shortcomings that part is more, complicated, assembling inconvenience, and manufacturing cost is high, and make it that switching is manual Specific product is big, is not easy to store and carries, therefore truly has the necessity improved.

The content of the invention

The present invention has in view of in order to solve the torque alarming structure of switching hand-held tool in the prior art Have manufacturing cost high and bulky shortcoming, there is provided one kind deform and send using shell fragment the sound with Reach the torque alarming structure of the switching hand-held tool of warning function.

The present invention provides a kind of torque alarming structure of switching hand-held tool, manual applied to a switching Tool, the switching hand-held tool have at least one trigger piece that switching hand-held tool can be driven to carry out switching action, The trigger piece is provided with a fulcrum and an at least point of application in a plane, and the torque alarming structure includes An at least shell fragment, an at least shell fragment is the trigger piece for being separately provided or being stacked and placed on the switching hand-held tool It is fixed at least on a point of application, the shell fragment is provided with a pushing portion and a contact site, utilization this support Height change between pushed section and contact site, makes the pushing portion and contact site have a difference in height, should The contact site of shell fragment contacts with the point of application of trigger piece；Thus, pushing portion drive can be pushed to pull Instrument rotation is changed hands, is tightened or unscrewed the switching action of screw tightening, and when screw tightening is turned round It is tight to predetermined elasticity cause the strength for pushing the pushing portion to be more than the deformation resistance of shell fragment when, bullet Sector-meeting is forced to be deformed and sends a sound, has the function that warning.

The main object of the present invention, it is that it is arranged at pulling for switching hand-held tool with an at least shell fragment Fixed on the point of application of handle, composition component is few, simple in construction, easy to assembly, reaches and is manufactured into This is low, meets the purpose of economic benefit.

Pulling for switching hand-held tool is arranged at an at least shell fragment it is another object of the present invention to it It is fixed on the point of application of handle, hardly increase switching hand-held tool volume, and be easy to store and carry.

Embodiment

Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are referred to, the present invention is a kind of torsion of switching hand-held tool Caution structure, applied to a switching hand-held tool 1, the switching hand-held tool 1 have can drive switching hand Instrument 1 carries out two trigger pieces 11 of switching action, and two trigger pieces 11 are in parallel side-by-side, wherein One trigger piece 11 is provided with a fulcrum 111 and a point of application 112 in a plane 113, the fulcrum 111 A force arm d is formed between the point of application 112, formed with an accommodating sky between another two trigger pieces 11 Between 12, be pivoted in the accommodation space 12 multiple rod tools first 13, the torque alarming structure bag Containing an at least shell fragment 2 and a sheath 3, an at least shell fragment 2 is flexible circular lamellar body, Fixed (this is separately provided or is stacked and placed on the point of application 112 of the trigger piece 11 of the switching hand-held tool 1 Embodiment is two shell fragments 2, and two shell fragments 2 are the trigger piece for being stacked and placed on the switching hand-held tool 1 It is fixed on 11 point of application 112), the shell fragment 2 is provided with a pushing portion 21 and a contact site 22, Changed using the height between the pushing portion 21 and contact site 22, make the pushing portion 21 and contact site 22 have a difference in height h, and the contact site 22 of the shell fragment 2 connects with the point of application 112 of trigger piece 11 Touch, the sheath 3 is made by the soft materials such as rubber, silica gel, is arranged and is incorporated into trigger piece 11 On the point of application 112, and the outside of an at least shell fragment 2 is coated on, its one side is held provided with one Support 31 and the pairing of pushing portion 21 of shell fragment 2.

Accordingly, as shown in figure 5, the rod tool of switching hand-held tool 1 first 13 is pivoted during use It is extremely vertical with trigger piece 11, and with being intended to the screw tightening (not shown) fit of switching, pass through sheath 3 support 31 of holding pushes the pushing portion 21 of shell fragment 2 and drives switching hand-held tool 1 to rotate, and is turned round Switching action that is tight or unscrewing screw tightening, when screw tightening is tightened to predetermined elasticity, and make to push When the strength of the pushing portion 21 of shell fragment 2 is more than the deformation resistance of shell fragment 2, then shell fragment 2 will be as It is forced to be deformed and sends using the difference in height h of pushing portion 21 and contact site 22 shown in Fig. 6 One sound, has the function that warning, to avoid applying the torsion of exertin, causes structure to consolidate with spiral shell Part loses effectiveness or damage.

Furthermore as shown in Fig. 7, Fig. 8 and Fig. 9, the torque alarming knot of switching hand-held tool of the present invention Structure, the trigger piece 11 of its switching hand-held tool 1 also can be set a fulcrum 111 and the first point of application 112a, Second point of application 112b is in a plane 113, shape between the fulcrum 111 and first point of application 112a Into one first force arm d1, one second force is formed between the fulcrum 111 and second point of application 112b Arm d2, and first force arm d1 is less than second force arm d2, and the shell fragment 2 is individually set Put or be stacked and placed on the first point of application 112a and second point of application of the trigger piece 11 of the switching hand-held tool 1 Fixed on 112b, the sheath 3 is arranged the first point of application 112a and second for being incorporated into trigger piece 11 On point of application 112b, and the outside of an at least shell fragment 2 is coated on, its one side is provided with two Pushing portion 21 and second of the support 31 respectively with the shell fragment 2 on the first point of application 112a is held to exert a force The pairing of pushing portion 21 of shell fragment 2 on point 112b.

Accordingly, in use, optional pass through sheath 3 two hold support 31 and push the first force Shell fragment 2 on the point of application 112b of pushing portion 21 or second of shell fragment 2 on point 112a pushes Portion 21, because the first force arm d1 is different from the second force arm d2 length, is tightened or revolved During the switching action of loose screw tightening, shell fragment 2 can be caused by forced labor under different torsion situations The shape that changes simultaneously sends a sound, reaches the effect of two-part torque alarming.

In addition, it can also be applied in setting three or more than three on the trigger piece 11 of switching hand-held tool 1 Force, thus reach Multi-segment torsion warning function.
