Description

A kind of electric hammer one button, four functional structure

Technical field

The utility model relates to electric tool, novel four functional structure of a button in especially a kind of electric hammer, hammer drill structure.

Background technique

Electric hammer, hammer drill are one kind using motor as power, drive a compression vacuum formula beater mechanism and a speed reducer Structure, output torque and impact energy make drill bit realize impact and cutting function, to reach in hard concrete, the materials such as rock The purpose to drill on material.The electric hammer, hammer drill of many types configure two switch knobs, all to reach in brill, hammer drill, hammer on the market Etc. switching use such as Fig. 1 between functions show, rear knob 1. with side cock 2. between be collocated with each other switching, brought not to user Just.Although there is the structure of some four functions of a button on the market at present, in the presence of structure is complicated, accessory assembles cumbersome ask Topic.

Utility model content

The utility model provides a kind of electric hammer one button, four functional structure, with two switch knobs of the prior art Switching is changed into the switching of a knob, by the cooperation of shift fork and the different location of clutch, to reach four function of a button Effect, with this come achieve the purpose that simplify operate and improve reliability.

The technical solution of the utility model is as follows:

A kind of electric hammer one button, four functional structure, including gear component, first gear component, second gear component, rotor； The gear component includes a mandrel, a shift fork, four gears, the first gear component from top to bottom include a tooth from Clutch spring, a tooth-like clutch, a tooth, the second gear component include two tooth-like clutch springs, two tooth-like clutch, two teeth, The rotor is set to a tooth, two tooth lower part；Four gears successively include four brill, hammer drill, neutral gear, hammer shelves Position；

One button, four functional structure stirs the switching that the shift fork realizes each function by the mandrel: two tooth Transmission is output to output shaft by two tooth-like clutch, transmission is output to defeated by a tooth by a tooth-like clutch Shaft, it is different that the rotation between them by the shift fork is respectively at two tooth-like clutch and a tooth-like clutch Switching between different function of the position to realize electric hammer.

Preferably, the rotor simultaneously with a tooth and two tooth engagement.

Preferably, four functional structure of a button can also be used in hammer drill structure.

Compared with prior art, the beneficial effects of the utility model are as follows:

The utility model mainly passes through brand-new design, and switching is changed into a knob with two switch knobs Switching to achieve the effect that four function of a button, reaches simplified by the cooperation of shift fork and the different location of clutch with this Operate and improve the purpose of reliability；The utility model using knob stirs single shift fork to realize the switching of each function simultaneously, It is smaller than volume with market structure, inner space can be saved, the monnolithic case of product is simplified.

Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.

Fig. 3 is the assembling schematic diagram of a button four functional structures axial direction of the utility model embodiment；

Wherein: 1- mandrel, 2- fork, mono- tooth-like clutch of 3-, 4 one teeth, 5 two teeth, 6 two tooth-like clutch, bis- tooth-like clutch of 7- Spring, clutch spring of 8-, 9- rotor.

Specific embodiment

The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate The utility model, rather than limit the protection scope of the utility model.Those skilled in the art are according to this in practical applications The modifications and adaptations that utility model is made, still fall within the protection scope of the utility model.

In order to better illustrate the utility model, the utility model is described in detail below with attached drawing.

Embodiment

Referring to Fig. 3 combination Fig. 2 (b), a kind of electric hammer one button, four functional structure, including gear component, first gear component, Second gear component, rotor；The gear component includes 2, four mandrel 1, shift fork gears, and the first gear component includes one Tooth-like clutch 3, a tooth 4, a tooth-like clutch spring 8, the second gear component include two tooth-like clutch 5, two teeth 6, two teeth from Clutch spring 7, the rotor 9 are set to a tooth 4 and two teeth, 6 lower part；Referring to fig. 2 (a), four gears are successively Including boring A, hammer drill B, neutral gear C, hammer tetra- gears of D；

One button, four functional structure stirs the switching that the shift fork 2 realizes each function: rotor 8 by the mandrel 1 Connection is engaged with a tooth 4, while rotor 8 engages connection with two teeth 5, rotation status, two teeth 5 are all kept when switching different function Transmission is output to output shaft by two tooth-like clutch 6, transmission is output to output shaft by a tooth-like clutch 3 by a tooth 4, they Between so that two tooth-like clutch 6 and a tooth-like clutch 3 is respectively at different positions to realize electric hammer not by the rotation of shift fork 2 Switching between congenerous.

When knob is directed toward A grade (brill), the mandrel 1 fluctuates the fork 2 and tilts to the left, make the clutch 3 and The gear 4 is detached from, and the two tooth-like clutch spring 7 compresses, and the gear 5 drives the clutch 6 to work in the position, is reached To only boring the function of not hammering.

When knob is directed toward B grades (hammer drill), the mandrel 1 stirs the shift fork 2 and is in free state, the tooth clutch Device spring 8 resets the clutch 3, and the clutch 3 and the gear 4, the clutch 6 are in the gear 5 Meshing state works at the same time, and reaches hammer drill function.

When knob is directed toward C grade (neutral gear), the mandrel 1 is stirred the shift fork 2 and is tilted to the right, the clutch 6 and The gear 5 is detached from, and the tooth-like clutch spring 9 compresses, and the clutch 3 is made to be in meshing state with the gear 4, Under the state, the resistance on head very little, directly with hand, that is, rotatable cylinder component, user it is expected chisel edge not when with flat chisel With position cope with different needs of work, thus user can be manually rotated drill bit in the state and have reached desired angle Degree.

When knob is directed toward D grades (hammer), the mandrel 1 is stirred the shift fork 2 and is tilted to the right, the clutch 6 and institute Gear 5 is stated after further increase, the clutch 6 is engaged with the stop part at other position, reaches the output end of electric hammer To complete lock state, the clutch 3 is in meshing state with the gear 4, reaches the function of only hammering.

The present embodiment is by brand-new design, and switching is changed into the switching of a knob with two switch knobs, By the cooperation of shift fork 2 and the different location of clutch, to achieve the effect that four function of a button, simplified operation is reached with this And improve the purpose of reliability；The present embodiment using knob mandrel 1 stirs single shift fork 2 to realize the switching of each function simultaneously, Volume wants small compared with the structure of market, can save inner space, simplifies the monnolithic case of product.

Certainly, this four functional structure of button can also be used in hammer drill structure, and principle and structure are referring to embodiment 1, herein not It repeats.

The preferred embodiment in the utility model disclosed above is only intended to help to illustrate the utility model.Preferred embodiment is simultaneously There is no the details that detailed descriptionthe is all, also not limiting the utility model is only the specific embodiment.Obviously, according to this theory The content of bright book can make many modifications and variations.These embodiments are chosen and specifically described to this specification, is in order to preferably The principles of the present invention and practical application are explained, so that skilled artisan be enable to better understand and utilize this Utility model.The utility model is limited only by the claims and their full scope and equivalents.
