Description
Technical field
The present invention relates to a kind of frame clamping structure for racket of racket threader.
Background technology
Racket such as tennis or shuttlecock must be fixed racquet frame with a clamping device earlier when threading, cooperates the setting of tension disk and drawing machine again, is worn racket string in racquet frame.
Be illustrated in figure 5 as existing threader frame clamping structure for racket (), it founds arm 91 and be arranged in the jig arm 92 of standing arm 91 tops by one forms, and on this upright arm 91 and jig arm 92, be respectively equipped with a hooked scarf 911 and two fixture blocks 921, inboard, major axis two ends by hooked scarf 911 grab racquet frame, and fixture block 921 clips the periphery outside of racquet frame, to reach the fixedly effect of racquet frame, but because the architrave of racket is not the structure of a Founder, moreover only with hook, the mode of folder and effectively fixing racquet frame, the influence of its pulling force when therefore causing the threader action and cause racquet frame unstable and rock, more severe patient makes racquet frame even can be out of shape and can't bear to use.
Other sees also Fig. 6, it is an another kind of existing racquet frame clamping device (two), be different from aforesaid frame clamping structure for racket, it is to be provided with a protruding seat 93 in upright arm 91, and this protruding seat 93 is provided with a press box spare 931 and two stop blocks 932, its fixedly the mode of racquet frame be that inboard, major axis two ends with racquet frame fastens in each stop block 932, and cooperate this press box spare 931 with should protruding seat time pressing mode clamping racquet frame more than 93.Yet, because this protruding seat 93 is to be based in this upright arm 91 inboards, can snap into this protruding seat 93 when resulting in racquet frame major axis end threading, and then smoothly threading in the racket end, therefore this clamping device is compared with aforesaid frame clamping structure for racket, though can increase the fixedly stability of racquet frame, can't reach the complete final purpose that makes racket threading.
See also Fig. 7 again, it shown in the figure another kind of frame clamping structure for racket (three), it comprises a upright arm 91, should be provided with jig arm 92 to both sides by upright arm 91, its characteristics are that each jig arm 92 is provided with a folder framework 94, each presss from both sides framework 94 and has a clip slot that Open Side Down 941, and the base surface that the architrave of racket is provided by jig arm 92, and with the folder framework 94 clip slot 941 grip the racquet frame periphery from top to bottom, though the clip slot 941 of folder framework 94 can meet the design of racket architrave, but because the base surface of this jig arm 92 is a plane, the racquet frame top is fixed when causing threading, and the below still has slippage, rock and situation such as instability.
See also Fig. 8 again, it is another kind of frame clamping structure for racket (four), it is to be provided with a pedestal 95 in jig arm 92, this pedestal 95 is provided with the nut 951 of an oblique setting, and is provided with a jaw 952 in these nut 951 ends, by precession or revolve and move back this nut 951, to reach urgent or to loosen racquet frame, yet because the section of racket is generally an ellipse, this structure still can't firmly make racquet frame be fixed by this clamping device.
When clamping device big more with the contact area of desiring gripping object, its chucking power is also just big relatively more, because of racquet frame is generally an elliptic jet, and the above-mentioned common disadvantage of racquet frame clamping device, be that itself and contacting of racquet frame are with Line To Line or with the mode clamping racquet frame in the face of line, and cause the chucking power deficiency, cause the racquet frame can't be by firm clamping.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcome the above-mentioned defective that prior art exists, and a kind of frame clamping structure for racket of racket threader is provided, the pulling force that it can avoid racquet frame to be produced when threading causes the unstable and situation of rocking of racquet frame.
The technical solution adopted for the present invention to solve the technical problems is:
