Description

Beat nail depth adjustment mechanism in the palm

Technical field

The utility model relates in a kind of palm hammer, hammers into shape in especially a kind of palm that has a mechanism that the nailing depth-adjustment connects.

Background technology

The nailing degree of depth of hammering into shape in the present palm on the market all is a fixed value, but actual environment for use often needs the different nailing degree of depth.Owing to little, the compact conformation of the own volume of hammer in the palm, be difficult to realize the scalable of the nailing degree of depth.U.S. Pat 7,316,342B2 discloses in a kind of palm of the scalable nailing degree of depth and has hammered into shape, and the hammer body below is connected with pin through the horizontal annular groove regulates seat, and therefore adjusting can horizontally rotate around hammer body.The contact site of regulating seat and hammer body is provided with and rotates gear mechanism, and described rotation gear mechanism comprises cooperating of the decorative pearl on top of an official cap that is provided with spring and groove, makes the rotation of regulating seat have gear to feel with this, in the nailing process, is unlikely rotation voluntarily.The striker that is used to impact nail passes the described axial line of regulating seat, also is with control panel, spring, fairlead on the striker from top to bottom, the lower end of fairlead pass the bottom of regulating seat be enclosed within nail around.Hold out against hammer body above the control panel, the following top that when nailing, holds out against fairlead of control panel.The following step that along the circumferential direction is arranged with of control panel; Described fairlead is connected rotation simultaneously with the adjusting seat through axle key; When rotating the adjusting seat, different step on the top touch controls dish of fairlead has axial displacement between fairlead and the hammer body; Thereby changed the size that striker exposes fairlead, influenced the nailing degree of depth.

Although this United States Patent (USP) has tentatively been realized the adjusting of the nailing degree of depth, because the restriction of hammer self size in the palm, control panel is very little; Can only set up the step of finite progression; Generally have only below 3 grades, have only the nailing degree of depth of finite progression to select, can not satisfy actual needs.

Summary of the invention

The utility model will overcome in the palm the few shortcoming of regulation stall of beating nail degree of depth mechanism, provides in a kind of palm that can realize the electrodeless adjusting nailing degree of depth to beat nail depth adjustment mechanism.

Beat nail depth adjustment mechanism in the described palm of the utility model; Comprise hammer body, fairlead, adjusting seat; The cylinder of described hammer body below is connected with pin through the horizontal annular groove regulates seat; The described contact site of regulating seat and hammer body is provided with and rotates gear mechanism, and described rotation gear mechanism comprises cooperating of the decorative pearl on top of an official cap that is provided with spring and groove, constitutes the gear of the rotation of adjusting; The lower end that is used to be enclosed within the fairlead around the nail passes the bottom of regulating seat; The striker that is used to impact nail hits nail along described fairlead and the axial line of regulating seat, its characteristic for fear of: the inner surface of the cylinder of described hammer body is with the swivel nut that has been threaded; Described swivel nut also is connected with described adjusting seat key; The end face of described swivel nut constitutes the axially movable limiting faces of described fairlead, is provided with spring between described swivel nut and the described fairlead.

Further, the cylinder of described hammer body below is provided with the horizontal annular groove, and described pin passes the locating hole that connects on the adjusting seat and embeds in the described groove.

Through rotating regulating sleeve, swivel nut rotates thereupon, because being threaded between swivel nut and the hammer body, swivel nut moves vertically.Because the end face of swivel nut constitutes the axially movable limiting faces of fairlead, the axial limit position of fairlead also changes, and then influences the size that striker exposes fairlead, and the degree of depth of nailing is able to regulate.

The advantage of the utility model is: can the electrodeless adjustment nailing degree of depth, and compact conformation, easy to use.

The specific embodiment

With reference to accompanying drawing:

Beat nail depth adjustment mechanism in the described palm of the utility model; Comprise hammer body 1, fairlead 3, regulate seat 4; The cylinder 11 of described hammer body 1 below is connected with pin 8 through horizontal annular groove 12 regulates seat 4; The described contact site of regulating seat 4 and hammer body 1 is provided with and rotates gear mechanism, and described rotation gear mechanism comprises cooperating of the decorative pearl on top of an official cap 6 that is provided with spring 5 and pit 41, constitutes the gear of regulating a rotation of 4; The lower end that is used to be enclosed within the fairlead 3 around the nail passes the bottom of regulating seat 4; The striker that is used to impact nail is along described fairlead 3 and the axial line strike nail of regulating seat 4, and the inner surface of the cylinder 11 of described hammer body 1 is with the swivel nut 2 that has been threaded; Described swivel nut 2 also is connected with described adjusting seat 4 keys; The end face of described swivel nut 2 constitutes the axially movable limiting faces of described fairlead 3, and 3 of described swivel nut 2 and described fairlead are provided with spring.

The cylinder 11 of described hammer body 1 below is provided with horizontal annular groove 12, and described pin 8 passes and connects in the described groove of regulating on the seat 4 12 of locating hole 9 embeddings.So, regulate between seat 4 and the hammer body 1 and can only relatively circumferentially rotate, and can not move axially.The end face that adjusting seat 4 contacts with hammer body 1 is provided with pit 41, and spring top bead 13 is housed on the hammer body 1, when seat 4 rotates shift feeling is arranged when regulating, and adjusting seat 4 can not rotate voluntarily when nailing.

Be provided with screw thread 21 between the inner surface of the cylinder 11 of swivel nut 2 and hammer body 1, swivel nut 2 also is connected with described adjusting seat 4 keys.The alleged key of this specification connects the flat side's connection that comprises like accompanying drawing 5 and is connected with the key shown in the accompanying drawing 6, also comprises the forms such as shaft shoulder connection of connection circular motion commonly used.

Through rotating regulating sleeve 4, swivel nut 2 rotates thereupon, because being threaded between swivel nut 2 and the hammer body 1, swivel nut 2 is mobile vertically.Because the end face of swivel nut 2 constitutes the axially movable limiting faces of fairlead 3, the axial limit position of fairlead 3 also changes, and then influences the size that striker exposes fairlead 3, and the degree of depth of nailing is able to regulate.

The described content of this specification embodiment only is enumerating the way of realization of utility model design; The scope of the protection of the utility model should not be regarded as and only limit to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
