The specific embodiment

By reference to the accompanying drawings, the utility model is described in further detail.

As shown in the figure, the utility model iron hammer is characterized in that: described spherical tup has comprised tup 10 and handle 12, and hammer 10 has a nape and tup belly 14, the critical wider striking face 16 in its termination and spherical tup 18; Also have impact groove and groove on the described spherical tup, groove has sidewall 1, sidewall 2 24, rear wall 26 and cuts down cross section central area 28; One end of described handle 12 places handle to hold in 34, and an end places in the groove, and the four sides of groove is to have carried out well suiting the position that makes handle 12 and striking face 16 be in balance with angle point 36; Described plastic bushing 40 is to be made by the resin of bump resistance in the local moulding of handle 12 and groove handing-over.Described groove part is oval-shaped, and handle 12 angle points 38 make the fine of itself and cross section break-in, and handle 12 is movable at the groove two ends of tup.Described reduction cross section central area 28 is to comprise on the transverse plane figure that clashes into axis.The groove part of described handle 12 is continuously unified with the intersection cross section of tup central recess.Described handle 12 is and a match pole 32 of length of unified cross section, is that the galss fiber reinforced resin that elongates is made.

As shown in the figure, the part of the indication number representational tool in the picture.This utility model comprises a spherical tup, and this spherical tup has comprised tup 10 and handle 12.The bump axis of tup (for example, the concentrated bump axis striking work of main strength) roughly extends towards the center of impact component to the summit of spherical tup from the center of striking face.No matter this axis remains unchanged the use of striking face or spherical tup.Set forth to some extent in an embodiment, the bump axis will be positioned at the line 3-3 position of figure 1 substantially.Central recess or central eye will be passed tup along the bump axis fully.As what see in figure 1 and 2, central recess has level and smooth sidewall 22, sidewall 24 and rear wall 26.Centrum is inwardly converged from the end of relative central recess, cuts down cross section central area 28 roughly on the bump axis thereby make.As showing in the image 3 that central area 28 presents ellipse.The port of export of central recess and arrival end may be rectangular shape or other shapes that can adapt to it.Yet, be the shape of generally adopting at the length ellipse of central recess.

In preferential embodiment, handle 12 is and a match pole 32 of length of unified cross section in fact, is that the galss fiber reinforced resin that elongates is made, and wraps in the suitable flexible lever 34.Handle has tetragonal cross section, can be unmovable on the intersection cross section of tup central recess, thus drop on groove.This characteristic is very important, and though be to the control of size and with the saving of the straight-bar of taper drift on, or all very important on the handle strength performance.Although the glass fiber resin pole is tetragonal, it has put on display the slight mobile curvature in sidewall.In figure 3, show, suppose that pole is that the shape that is fit to of tetragonal words may be determined by the concrete size of the central eye of the size of pole and iron hammer.Yet the angle point 36 of the pole of central recess should interference fit central recess 28, and central recess 28 has minimum intersection opening, and these angle points also should done good break-in with cinclides on the degree of friction He on the angle.This helps the adjustment of relevant with the longitudinal axis of handle to a certain extent tup angle, and this adjustment can avoid large-scale production to the defective brought on the impact component and on handle.Angle point by unique handle and sidewall central recess on degree of friction on all directions intimately agree with very important to a certain extent.Be actually on their whole length at the narrowest central recess, the wall of handle and central recess keep spacing.In addition, because this ellipse, the sidewall of the main bump axis with opposition of contact point and rear wall 24,26 are together.Thereby, between the quadrangle in the center line hole of handle and wall, set up direct and intimate contact.So just provide a fulcrum to make the versatility of universal joint also can make the striking face relevant with iron hammer handle and handle carry out multi-direction adjustment.Except uncertainty and the defective of central recess or impact component or handle subdivision, the equilbrium position of handle can reach the position of balance by above-mentioned adjustment.

Be understandable that adjustable interconnection can guarantee that power makes at handle and holds on 34 but not the part of the central recess of handle between the handle of new and improved mistake and the tup.By such mode, the position that determines correct handle to hold position and user's hand will have precedence over the step that connects handle and tup.Thus, can guarantee fully that with striking face or in the tram that the handle of the contact-making surface of this related elements is held with handle subsequent operation can not influence the center equilibrium relation between striking face and the implement handle.After handle 12 was inserted the central recess of striking face with effective distance, the position of front end can far exceed the bump axis of impact component, and front end can be in its position of closing on.But handle and striking face may because of embed the rear end produce spin or angle on the transformation of position, this transformation can provide the relevant position exercise of wanting.Thus, to seal by the material tyre bead 38 that is used for sealing at the central recess of entrance, for example suchlike material such as organic siliconresin.So, handle just can be buckled together tightly with tup, fully prevents in pothole, and the suitable impact resistance resin material around central fovea cell wall and the tup for example epoxy resin etc. has defined the boundary of this pothole.After these material cured, the central recess with the handle two ends in the central recess circle forms sleeve pipe 40.Epoxy resin bushing 40 only can block at the angle point 36 of handle and the intersection of cross section 28 parts.The essence of resin has determined resin to fill up pothole at leisure, flows to the opposite end in hole, forms at last and the pothole sleeve pipe that is harmonious, thereby has strengthened thickness.

So as can be seen, implement handle was closely joined together when this utility model made impact component and bump from above-mentioned detailed description.This associating handle and striking face are in safety and position accurately, and component and the feel of giving the tool focus balance, also meet the standard of defined in mass production of products clauses and subclauses and the technology simultaneously.
