Description

Pin-mounting hand-held tool with damping spring

Technical Field

The utility model relates to a hand tool especially relates to a take damping spring's dress round pin hand tool, and it belongs to dress round pin equipment technical field.

Background

The pin installing tool is a manual pin installing tool and needs to be matched with a hammer for knocking, the conventional pin installing handheld tool is shown in figure 1, a user can hit a knocking part by the hammer after holding the handheld part, the hand of the user can be strongly vibrated and impacted in the using process, the hands and the arms of the user are numb and uncomfortable due to continuous operation, and safety accidents are easily caused. Therefore, there is a need for a pin-loading hand tool with a shock-absorbing design, which has a simple structure and a shock-absorbing function, and can reduce the influence of shock and impact force on the hand of a user, thereby improving ergonomics.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: for overcoming the not enough of existence among the prior art, the utility model provides a take damping spring's dress round pin hand-held tool, simple structure, the cost is with low costs, has good shock-absorbing function.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a take damping spring's dress round pin hand-held tool, includes the key seat, handheld portion and the portion of strikeing that connect gradually, handheld portion includes stamping rod, first spring, handle cover and second spring, the stamping rod sets up between key seat and the portion of strikeing, first spring, handle cover and second spring are established in proper order on stamping rod, key seat and handle cover are through first spring elastic connection, handle cover and the portion of strikeing pass through second spring elastic connection, handle cover can follow stamping rod axial motion.

Still further, the diameter of the punch stem is less than the diameter of the pin boss and the peened portion.

Furthermore, one side of the handle sleeve, which is close to the knocking part, is provided with a protective check ring.

Further, the diameter of the handle sleeve is smaller than that of the retainer ring.

Furthermore, the handle sleeve is made of rubber, and flanges which are integrally formed are arranged at two ends of the handle sleeve.

Furthermore, the knocking part and the punching rod are integrally formed, and the tail part of the knocking part is in the shape of a circular boss.

Furthermore, a positioning pin is arranged at the front end of the pin seat.

Compared with the prior art, the beneficial effects of the utility model are that: adopt the shock-absorbing structure design that depression bar, first spring, handle cover and second spring combine, improve the handheld portion, convenient to use has reduced in the use, and vibrations and impact force have improved human-machine engineering to the influence of user's hand. The utility model discloses simple structure, low in manufacturing cost is easily extensively promoted.

Drawings

FIG. 1 is a schematic diagram of a prior art structure;

fig. 2 is a schematic structural diagram of the present invention.

In the figure, 1, a pin boss; 2. a hand-held portion; 3. a knocking portion; 4. a stamping rod; 5. a first spring; 6. a handle sleeve; 7. a second spring; 8. a retainer ring; 9. a flange; 10. and a positioning pin.

Detailed Description

The principles and features of the present invention will be described with reference to the accompanying fig. 1-2, wherein the examples are provided for illustration only and are not intended to limit the scope of the invention.

As shown in figure 2, a take damping spring's dress round pin hand tool, including the round pin seat 1, handheld portion 2 and the portion of strikeing 3 that connect gradually, handheld portion 2 includes stamping rod 4, first spring 5, handle cover 6 and second spring 7, stamping rod 4 sets up between round pin seat 1 and the portion of strikeing 3, first spring 5, handle cover 6 and second spring 7 overlap in proper order and establish on stamping rod 4, round pin seat 1 and handle cover 6 are through first spring 5 elastic connection, handle cover 6 and portion of strikeing 3 are through second spring 7 elastic connection, 4 axial motion of stamping rod can be followed to handle cover 6, through this kind of shock-absorbing structure of handheld portion 2, reduce vibrations and the influence of impact force to user's hand.

The diameter of the punching rod 4 is smaller than that of the pin boss 1 and the knocking part 3, so that the first spring 5, the handle sleeve 6 and the second spring 7 are conveniently sleeved and limited between the pin boss 1 and the knocking part 3, and the first spring 5, the handle sleeve 6 and the second spring 7 are conveniently sleeved and limited between the pin boss 1 and the knocking part 3.

One side of the handle sleeve 6 close to the knocking part 3 is provided with a protective retainer ring 8. The diameter of the handle sleeve 6 is smaller than that of the retainer ring 8, so that the retainer ring 8 plays a role in protection and prevents hands holding the handle sleeve 6 from being injured.

The handle sleeve 6 is made of rubber, flanges 9 which are integrally formed are arranged at two ends of the handle sleeve, lines are arranged on the surface of the rubber, and a user can hold the handle sleeve 6 more stably and firmly; and the flanges 9 on the two sides of the handle sleeve 6 are designed, so that a user can hold the handle sleeve 6 conveniently, and the safety is improved.

Knocking part 3 and punching rod 4 integrated into one piece, the shape of its afterbody is circular boss, and the increase is hit and is beaten the contact surface, has improved the security.

And a positioning pin 10 is arranged at the front end of the pin seat 1.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
